Accumulated deferred income taxes and taxes accrued($4,734,737)($4,652,611)
Entergy’s estimated tax attributes carryovers and their expiration dates as of December 31, 2022 are as follows:
Carryover DescriptionCarryover AmountYear(s) of expiration
   
Federal net operating losses before 1/1/2018$6.2 billion2023-2027
Federal net operating losses - 1/1/2018 forward$20.1 billionN/A
State net operating losses$7.7 billion2023-2042
State net operating losses with no expiration$15.7 billionN/A
Other federal and state carryforwards$515.7 million2023-2027
Miscellaneous federal and state credits$90.1 million2023-2042

As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers, tax credit carryovers, and other tax attributes reflected on income tax returns. Entergy evaluates the available positive and negative evidence to estimate whether sufficient future taxable income of the appropriate character will be generated to realize the benefits of existing deferred tax assets. When the evaluation indicates that Entergy will not be able to realize the existing benefits, a valuation allowance is recorded to reduce deferred tax assets to the realizable amount.

Because it is more likely than not that the benefits from certain state net operating losses and other deferred tax assets will not be utilized, valuation allowances totaling $372 million as of December 31, 2022 and $325 million as of December 31, 2021 have been provided on the deferred tax assets related to federal and state jurisdictions in which Entergy does not currently expect to be able to utilize certain separate company tax return attributes, preventing realization of such deferred tax assets. As a result of incurring costs related to Hurricane Ida restoration, certain Utility operating companies are entitled to an accelerated tax deduction which generated a taxable loss in various taxing jurisdictions. This accelerated deduction has impaired the realizability of a limited term carryover tax attribute. Accordingly, the impairment contributed to the activity reflected for the valuation allowance disclosed above.

As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers and tax credit carryovers.

Unrecognized tax benefits

Accounting standards establish a “more-likely-than-not” recognition threshold that must be met before a tax benefit can be recognized in the financial statements.  If a tax deduction is taken on a tax return but does not meet the more-likely-than-not recognition threshold, an increase in income tax liability, above what is payable on the tax return, is required to be recorded.  A reconciliation of Entergy’s beginning and ending amount of unrecognized tax benefits is as follows:

The balances of unrecognized tax benefits include $3,254 million, $2,256 million, and $2,208 million as of December 31, 2022, 2021, and 2020, respectively, which, if recognized, would lower the effective income tax rates.  Because of the effect of deferred tax accounting, the remaining balances of unrecognized tax benefits of $3,140 million, $3,504 million, and $3,491 million as of December 31, 2022, 2021, and 2020, respectively, if disallowed, would not affect the annual effective income tax rate but would accelerate the payment of cash to the taxing authority to an earlier period.

Entergy accrues interest expense, if any, related to unrecognized tax benefits in income tax expense.  Entergy’s December 31, 2022, 2021, and 2020 accrued balance for the possible payment of interest is approximately $50 million, $52 million, and $44 million, respectively. Interest (net-of-tax) of ($2) million, $8 million, and ($4) million was recorded in 2022, 2021, and 2020, respectively.

Income Tax Audits

Entergy and its subsidiaries file U.S. federal and various state income tax returns.  IRS examinations are complete for years before 2016. All state taxing authorities’ examinations are complete for years before 2014. Entergy regularly defends its positions and works with the IRS to resolve audits.  The resolution of audit issues could result in significant changes to the amounts of unrecognized tax benefits in the next twelve months.

2014-2015 IRS Audit

The IRS completed its examination of the 2014 and 2015 tax years and issued its 2014-2015 RAR in November 2020. Entergy agreed to all proposed adjustments contained in the RAR. Entergy and the Registrant Subsidiaries recorded the effects of the adjustments associated with the audit in 2020.

In October 2015 two of Entergy’s Louisiana utilities, Entergy Gulf States Louisiana and Entergy Louisiana, combined their businesses into a legal entity which is identified as Entergy Louisiana herein. The structure of the business combination required Entergy to recognize a gain for income tax purposes which resulted in an increase in the tax basis of the assets for Entergy Louisiana. This resulted in recognition in 2015 of a $334 million permanent difference and income tax benefit, net of the uncertain tax position recorded on the transaction.

Primarily related to resolution of the business combination issues, completion of the 2014-2015 IRS audit in 2020 resulted in a $230 million reduction to deferred income tax expense for Entergy. This reduction to deferred income tax expense includes: Entergy Louisiana reversing its provision for uncertain tax position with respect to the business combination, which resulted in a reduction to deferred income tax expense of $383 million; Entergy Corporation recording an increase to deferred tax expense of $61 million and Entergy Wholesale Commodities recording an increase to deferred tax expense of $105 million from the re-measurement of deferred tax assets associated with the resolved uncertain tax position; and miscellaneous other individually insignificant benefits totaling $13 million.

The completion of the 2014-2015 tax audit also resulted in a $31 million reduction to income tax expense associated with Entergy Louisiana’s method of accounting related to the adoption of tangible property regulations. As a result of the settlement of the tangible property regulation tax position, Entergy Louisiana was required to record a $33 million ($24 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to customers pursuant to a prior regulatory settlement.

Finally, upon completion of the 2014-2015 tax audit, Entergy New Orleans recorded a reduction to income tax expense of $8 million associated with claims for mark-to-market deductions.

In the first quarter 2020, Entergy and the IRS agreed on the treatment of funds received by Entergy Louisiana in conjunction with the Act 55 financing of Hurricane Isaac storm costs, which resulted in a net reduction
of income tax expense of approximately $32 million. As a result of the settlement, the position was partially sustained, and Entergy Louisiana recorded a reduction of income tax expense of approximately $58 million primarily due to the reversal of a provision for uncertain tax positions in excess of the agreed-upon settlement. As a result of the IRS settlement, Entergy Louisiana recorded a $29 million ($21 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to customers pursuant to the LPSC Hurricane Isaac Act 55 financing order.

Additional effects of the completion of the 2014-2015 IRS tax audit are discussed below within Tax Accounting Methods.

State Income Tax Audits

As a result of income tax audit adjustments proposed by the Arkansas Department of Finance and Administration, an Entergy Wholesale Commodities subsidiary recorded a provision in third quarter 2022 for uncertain tax positions of approximately $21 million, which includes interest expense.

Other Tax Matters

Tax Cuts and Jobs Act (TCJA)

The most significant effect of the TCJA for Entergy and the Registrant Subsidiaries was the change in the federal corporate income tax rate from 35% to 21%, effective January 1, 2018.

TCJA also limited the deduction for net business interest expense to 30 percent of adjusted taxable income, which is similar to earnings before interest, taxes, depreciation, and amortization. The limitation does not apply to interest expense that is properly allocable to a trade or business classified as a regulated public utility. This was further modified by a temporary provision of the CARES Act resulting in an increase of the adjusted taxable income limitation from 30% to 50% for tax years that begin in 2019 or 2020.

The IRS issued final regulations which were effective for Entergy beginning with the 2021 tax year. The regulations provide that if 90% of a tax group’s consolidated assets consist of regulated utility property, the entire consolidated tax group will be treated as a regulated public utility and all of the consolidated group’s interest expense will be currently tax deductible. Entergy expects that its classification as a public utility will continue to apply to its business operations making the application of the interest expense limitation to Entergy unlikely. The provision has not resulted in Entergy having to report any significant business interest expense limitations on its tax returns.

With respect to the federal corporate income tax rate change from 35% to 21% in 2017, Entergy and the Registrant Subsidiaries recorded a regulatory liability associated with the decrease in the net accumulated deferred income tax liability, which is often referred to as “excess ADIT,” a significant portion of which has been paid to customers since 2019 in the form of lower rates. Entergy’s December 31, 2022 and December 31, 2021 balance sheets reflect a regulatory liability of $1.3 billion and $1.3 billion, respectively, as a result of the re-measurement of deferred tax assets and liabilities from the income tax rate change, amortization of excess ADIT, and payments to customers since the enactment of TCJA.
Entergy’s regulatory liability for income taxes includes a gross-up at the applicable tax rate because of the effect that excess ADIT has on the ratemaking formula. The regulatory liability for income taxes includes the effect of a) the reduction of the net deferred tax liability resulting in excess ADIT, and b) the tax gross-up of excess ADIT. The Registrant Subsidiaries’ December 31, 2022 and December 31, 2021 balance sheets reflect net regulatory liabilities for income taxes as follows:
20222021
(In Millions)
Entergy Arkansas$435 $432 
Entergy Louisiana$338 $338 
Entergy Mississippi$202 $212 
Entergy New Orleans$40 $42 
Entergy Texas$133 $171 
System Energy$111 $113 

Excess ADIT is generally classified into two categories: 1) the portion that is subject to the normalization requirements of the TCJA, referred to as “protected”, and 2) the portion that is not subject to such normalization provisions, referred to as “unprotected”. The TCJA provides that the normalization method of accounting for income taxes is required for excess ADIT associated with public utility property. The TCJA provides for the use of the average rate assumption method (ARAM) for the determination of the timing of the return of excess ADIT associated with such property. Under ARAM, the excess ADIT is reduced over the remaining life of the asset. Remaining asset lives vary for each Registrant Subsidiary, but the average life of public utility property is typically 30 years or longer. Entergy will amortize the protected portion of the excess ADIT in conformity with the normalization requirements. The Registrant Subsidiaries’ net regulatory liability for income taxes as of December 31, 2022 and December 31, 2021, includes protected excess ADIT as follows:
20222021
(In Millions)
Entergy Arkansas$453 $463 
Entergy Louisiana$675 $669 
Entergy Mississippi$226 $237 
Entergy New Orleans$53 $56 
Entergy Texas$201 $208 
System Energy$137 $148 

Payment of the unprotected excess accumulated deferred income taxes results in a reduction in the regulatory liability for income taxes and a corresponding reduction in income tax expense. This has a significant effect on the effective tax rate for the period as compared to the statutory tax rate. The Registrant Subsidiaries’ net regulatory liability for income taxes as of December 31, 2022 and December 31, 2021, includes unprotected excess ADIT as follows:
20222021
(In Millions)
Entergy Arkansas$27 $12 
Entergy Louisiana$135 $148 
Entergy Texas$— $26 
The return of unprotected excess accumulated deferred income taxes reduced Entergy’s and the Registrant Subsidiaries’ regulatory liability for income taxes as follows for 2022 and 2021:
20222021
(In Millions)
Entergy$53 $88 
Entergy Arkansas$— $8 
Entergy Louisiana$25 $33 
Entergy New Orleans$1 $1 
Entergy Texas$27 $28 
System Energy$— $18 

In addition to the protected and unprotected excess ADIT amounts, the net regulatory liability for income taxes includes other regulatory assets and liabilities for income taxes associated with AFUDC, which is described in Note 1 to the financial statements.

Included in the effect of the computation of the changes in deferred tax assets and liabilities is the recognition threshold and measurement of uncertain tax positions resulting in unrecognized tax benefits. The final economic outcome of such unrecognized tax benefits is generally the result of a negotiated settlement with the IRS that often differs from the amount that is recorded as realizable under GAAP. The intrinsic uncertainty with respect to all such tax positions means that the difference between current estimates of such amounts likely to be realized and actual amounts realized upon settlement may have an effect on income tax expense and the regulatory liability for income taxes in future periods.

Entergy anticipates that the effect of TCJA may continue to have ramifications that require adjustments in the future as certain events occur. These events include: 1) IRS audit adjustments to or amendments of federal and state income tax returns that include modifications to the computation of taxable income resulting from TCJA; and 2) additional guidance, interpretations, or rulings by the U.S. Department of the Treasury or the IRS. The potential exists for these types of events to result in future tax expense adjustments because of the difference in the federal corporate income tax rate between past and future periods and the effect of the tax rate change on ratemaking. In turn, these events also could potentially affect the regulatory liability for income taxes.

Coronavirus Aid, Relief, and Economic Security Act

In response to the economic impacts of the COVID-19 pandemic, President Trump signed the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) into law on March 27, 2020. The CARES Act provisions that result in the most significant opportunities for tax relief to Entergy and the Registrant Subsidiaries are (i) permitting a five-year carryback of 2018-2020 NOLs, (ii) removing the 80 percent limitation on NOLs carried to tax years beginning before 2021, (iii) increasing the limitation on interest expense deductibility for 2019 and 2020, (iv) accelerating available refunds for minimum tax credit carryforwards, modifying limitations on charitable contributions during 2020, and (v) delaying the payment of employer payroll taxes. Entergy deferred approximately $64 million of 2020 payroll tax payments, payable in equal installments over two years. The initial installment of $32 million was paid in December 2021. The second installment of $32 million was paid in December 2022.

Inflation Reduction Act of 2022

The Inflation Reduction Act of 2022, signed into law on August 16, 2022, significantly expanded federal tax incentives for clean energy production, including the extension of production tax credits to solar projects and certain qualified nuclear power plants. Additionally, the Inflation Reduction Act of 2022 enacted a 1% excise tax on the buyback of public company stock and a new corporate alternative minimum tax. There are no effects on the financial statements as of and for the year ended December 31, 2022 related to the enactment of the law. See the
Income Tax Legislation” section of Entergy Corporation and Subsidiaries Management’s Financial Discussion and Analysis for additional discussion of the effects of the Inflation Reduction Act of 2022.

Entergy Wholesale Commodities Restructuring

In the fourth quarter 2020, Entergy’s ownership of Palisades was restructured. The restructuring required Entergy to recognize Palisades’ nuclear decommissioning liability for income tax purposes resulting in a tax accounting permanent difference that reduced income tax expense, net of unrecognized tax benefits, by $9.2 million. The accrual of the nuclear decommissioning liability also required Entergy to recognize a gain for income tax purposes, a portion of which resulted in an increase in the tax basis of the assets. Recognition of the gain and the increase in the tax basis of the assets represents a tax accounting temporary difference.

Tax Accounting Methods

In the fourth quarter 2015, System Energy and Entergy Louisiana adopted a new method of accounting for income tax return purposes in which their nuclear decommissioning costs will be treated as production costs of electricity includable in cost of goods sold. The new method resulted in a reduction of taxable income of $1.2 billion for System Energy and $2.2 billion for Energy Louisiana.

In conjunction with the 2014-2015 IRS audit discussed above, the IRS issued proposed adjustments concerning the nuclear decommissioning tax position allowing System Energy to include $102 million of its decommissioning liability in cost of goods sold, and Entergy Louisiana to include $221 million of its decommissioning liability in cost of goods sold. Entergy, System Energy, and Entergy Louisiana agreed to the proposed adjustments included in the RAR.

As a result of System Energy being allowed to include part of its decommissioning liability in cost of goods sold, System Energy and Entergy recorded a deferred tax liability of $26 million at the time the matter was agreed upon. System Energy also recorded federal and state taxes payable of $402 million. However, on a consolidated basis, Entergy utilized tax loss carryovers to offset the federal taxable income adjustment and did not record federal taxes payable as a result of the outcome of this uncertain tax position.

As a result of Entergy Louisiana being allowed to include part of its decommissioning liability in cost of goods sold, Entergy Louisiana and Entergy recorded a deferred tax liability of $60 million at the time the matter was agreed upon. Both Entergy Louisiana and Entergy utilized tax loss carryovers to offset the taxable income adjustment and accordingly did not record taxes payable as a result of the outcome of this uncertain tax position.

The partial disallowance of this uncertain tax position to include the decommissioning liability in cost of goods sold resulted in a $1.5 billion decrease in the balance of unrecognized tax benefits related to federal and state taxes for Entergy. Additionally, both System Energy and Entergy Louisiana recorded a reduction to their balances of unrecognized tax benefits for federal and state taxes of $461 million and $1.1 billion, respectively.

Entergy Arkansas adopted the same method of accounting for its nuclear decommissioning costs which resulted in a $1.8 billion reduction in taxable income on its 2018 tax return.

In 2016, Entergy Louisiana elected mark-to-market income tax treatment for various wholesale electric power purchase and sale agreements, including Entergy Louisiana’s contract to purchase electricity from the Vidalia hydroelectric facility and from System Energy under the Unit Power Sales Agreement. The election resulted in a $2.2 billion deductible temporary difference. In 2017, Entergy New Orleans also elected mark-to-market income tax treatment for wholesale electric contracts which resulted in a $1.1 billion deductible temporary difference. In 2018, Entergy Arkansas and Entergy Mississippi accrued deductible temporary differences related to mark-to-market tax accounting for wholesale electric contracts of $2.1 billion and $1.9 billion, respectively. Additionally, in
2020, Entergy Texas elected mark-to-market income tax treatment for wholesale electric power purchase and sale agreements which resulted in a $2.5 billion deductible temporary difference.

Arkansas and Louisiana Corporate Income Tax Rate Changes

In April 2019, December 2021, and August 2022 the State of Arkansas enacted corporate income tax law changes that phased in rate reductions from the former rate of 6.5% to 6.2% in 2021, and 5.9% in 2022.  The August 2022 legislation accelerated the rate reduction to 5.3% for tax years beginning on or after January 1, 2023, accelerating the rate reductions that were originally scheduled to take effect in the 2025 tax year. As a result of the 2019 rate reduction, Entergy Arkansas computed a regulatory liability for income taxes as of December 31, 2020 of approximately $21 million, which includes a tax gross-up related to the treatment of income taxes in the retail and wholesale ratemaking formulas and has been included in the appropriate rate mechanisms. Entergy Arkansas recorded incremental regulatory liabilities of $11 million and $15 million associated with the rate reductions enacted in 2021 and 2022, respectively. The Arkansas tax law enactment also phases in an increase to the net operating loss carryover period from five to ten years.

Pursuant to legislation enacted in 2021 and approved by Louisiana citizens by amendment to the state constitution, beginning January 1, 2022, federal income taxes paid will no longer be deductible for state income tax purposes, and the top Louisiana corporate income tax rate will be reduced from 8% to 7.5%. As a result of this change in Louisiana tax law, the Louisiana applicable tax rate increased by 0.85%. Accordingly, deferred tax assets and liabilities were adjusted to reflect the new applicable federal and state rates. Legislation enacted in 2021 also provides that Louisiana net operating losses generally have an indefinite carryover period.

Entergy recorded a net increase to its deferred tax asset of $27 million. Entergy Louisiana and Entergy New Orleans recorded net increases to their deferred tax liabilities before consideration of the tax gross-up of $77 million and $8 million, respectively, which were offset by regulatory assets for income taxes. Therefore, these increases had no effect on tax expense. However, the increase of deferred tax assets associated with certain assets reduced tax expense for Entergy Louisiana and Entergy New Orleans by $6 million and $2 million, respectively.

Stock Compensation

In accordance with stock compensation accounting rules, Entergy and the Registrant Subsidiaries recognized excess tax deductions as a reduction of income tax expense in the first quarter 2020. Due to the vesting and exercise of certain Entergy stock-based awards, Entergy recorded a permanent tax reduction of approximately $24.7 million, including $4.8 million for Entergy Arkansas, $8.6 million for Entergy Louisiana, $2.7 million for Entergy Mississippi, $1.5 million for Entergy New Orleans, $2.7 million for Entergy Texas, and $1.3 million for System Energy.

Act 293 Securitization

As described in Note 2 to the financial statements, Entergy Louisiana implemented a securitization authorized under Act 293 of the Louisiana legislature. Act 293 provides that the LURC contribute the net bond proceeds to a LURC-sponsored trust. Over the 15-year term of the Act 293 bonds, the storm trust will make distributions to Entergy Louisiana, a beneficiary of the storm trust, that will not be taxable to Entergy Louisiana. Additionally, Entergy Louisiana will not include the receipt of the system restoration charges in taxable income because the right to receive the system restoration charges has been granted directly to the LURC, and Entergy Louisiana only acts as an agent to collect those charges on behalf of the LURC.

Accordingly, the securitization provides for a tax accounting permanent difference resulting in a net reduction of income tax expense in second quarter 2022 of approximately $290 million, after taking into account a provision for uncertain tax positions, by Entergy Louisiana. Entergy’s recognition of reduced income tax expense
was offset by other tax charges resulting in a net reduction of income tax expense of $283 million, after taking into account a provision for uncertain tax positions.

In recognition of its obligations related to an LPSC ancillary order issued as part of the securitization regulatory proceeding, Entergy Louisiana recorded in second quarter 2022 a $224 million ($165 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to share the benefits of the securitization with customers. See Note 2 to the financial statements for discussion of the Entergy Louisiana securitization.

Entergy’s estimated tax attributes carryovers and their expiration dates as of December 31, 2022 are as follows:
Carryover DescriptionCarryover AmountYear(s) of expiration
   
Federal net operating losses before 1/1/2018$6.2 billion2023-2027
Federal net operating losses - 1/1/2018 forward$20.1 billionN/A
State net operating losses$7.7 billion2023-2042
State net operating losses with no expiration$15.7 billionN/A
Other federal and state carryforwards$515.7 million2023-2027
Miscellaneous federal and state credits$90.1 million2023-2042

As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers, tax credit carryovers, and other tax attributes reflected on income tax returns. Entergy evaluates the available positive and negative evidence to estimate whether sufficient future taxable income of the appropriate character will be generated to realize the benefits of existing deferred tax assets. When the evaluation indicates that Entergy will not be able to realize the existing benefits, a valuation allowance is recorded to reduce deferred tax assets to the realizable amount.

Because it is more likely than not that the benefits from certain state net operating losses and other deferred tax assets will not be utilized, valuation allowances totaling $372 million as of December 31, 2022 and $325 million as of December 31, 2021 have been provided on the deferred tax assets related to federal and state jurisdictions in which Entergy does not currently expect to be able to utilize certain separate company tax return attributes, preventing realization of such deferred tax assets. As a result of incurring costs related to Hurricane Ida restoration, certain Utility operating companies are entitled to an accelerated tax deduction which generated a taxable loss in various taxing jurisdictions. This accelerated deduction has impaired the realizability of a limited term carryover tax attribute. Accordingly, the impairment contributed to the activity reflected for the valuation allowance disclosed above.

As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers and tax credit carryovers.

Unrecognized tax benefits

Accounting standards establish a “more-likely-than-not” recognition threshold that must be met before a tax benefit can be recognized in the financial statements.  If a tax deduction is taken on a tax return but does not meet the more-likely-than-not recognition threshold, an increase in income tax liability, above what is payable on the tax return, is required to be recorded.  A reconciliation of Entergy’s beginning and ending amount of unrecognized tax benefits is as follows:

The balances of unrecognized tax benefits include $3,254 million, $2,256 million, and $2,208 million as of December 31, 2022, 2021, and 2020, respectively, which, if recognized, would lower the effective income tax rates.  Because of the effect of deferred tax accounting, the remaining balances of unrecognized tax benefits of $3,140 million, $3,504 million, and $3,491 million as of December 31, 2022, 2021, and 2020, respectively, if disallowed, would not affect the annual effective income tax rate but would accelerate the payment of cash to the taxing authority to an earlier period.

Entergy accrues interest expense, if any, related to unrecognized tax benefits in income tax expense.  Entergy’s December 31, 2022, 2021, and 2020 accrued balance for the possible payment of interest is approximately $50 million, $52 million, and $44 million, respectively. Interest (net-of-tax) of ($2) million, $8 million, and ($4) million was recorded in 2022, 2021, and 2020, respectively.

Income Tax Audits

Entergy and its subsidiaries file U.S. federal and various state income tax returns.  IRS examinations are complete for years before 2016. All state taxing authorities’ examinations are complete for years before 2014. Entergy regularly defends its positions and works with the IRS to resolve audits.  The resolution of audit issues could result in significant changes to the amounts of unrecognized tax benefits in the next twelve months.

2014-2015 IRS Audit

The IRS completed its examination of the 2014 and 2015 tax years and issued its 2014-2015 RAR in November 2020. Entergy agreed to all proposed adjustments contained in the RAR. Entergy and the Registrant Subsidiaries recorded the effects of the adjustments associated with the audit in 2020.

In October 2015 two of Entergy’s Louisiana utilities, Entergy Gulf States Louisiana and Entergy Louisiana, combined their businesses into a legal entity which is identified as Entergy Louisiana herein. The structure of the business combination required Entergy to recognize a gain for income tax purposes which resulted in an increase in the tax basis of the assets for Entergy Louisiana. This resulted in recognition in 2015 of a $334 million permanent difference and income tax benefit, net of the uncertain tax position recorded on the transaction.

Primarily related to resolution of the business combination issues, completion of the 2014-2015 IRS audit in 2020 resulted in a $230 million reduction to deferred income tax expense for Entergy. This reduction to deferred income tax expense includes: Entergy Louisiana reversing its provision for uncertain tax position with respect to the business combination, which resulted in a reduction to deferred income tax expense of $383 million; Entergy Corporation recording an increase to deferred tax expense of $61 million and Entergy Wholesale Commodities recording an increase to deferred tax expense of $105 million from the re-measurement of deferred tax assets associated with the resolved uncertain tax position; and miscellaneous other individually insignificant benefits totaling $13 million.

The completion of the 2014-2015 tax audit also resulted in a $31 million reduction to income tax expense associated with Entergy Louisiana’s method of accounting related to the adoption of tangible property regulations. As a result of the settlement of the tangible property regulation tax position, Entergy Louisiana was required to record a $33 million ($24 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to customers pursuant to a prior regulatory settlement.

Finally, upon completion of the 2014-2015 tax audit, Entergy New Orleans recorded a reduction to income tax expense of $8 million associated with claims for mark-to-market deductions.

In the first quarter 2020, Entergy and the IRS agreed on the treatment of funds received by Entergy Louisiana in conjunction with the Act 55 financing of Hurricane Isaac storm costs, which resulted in a net reduction
of income tax expense of approximately $32 million. As a result of the settlement, the position was partially sustained, and Entergy Louisiana recorded a reduction of income tax expense of approximately $58 million primarily due to the reversal of a provision for uncertain tax positions in excess of the agreed-upon settlement. As a result of the IRS settlement, Entergy Louisiana recorded a $29 million ($21 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to customers pursuant to the LPSC Hurricane Isaac Act 55 financing order.

Additional effects of the completion of the 2014-2015 IRS tax audit are discussed below within Tax Accounting Methods.

State Income Tax Audits

As a result of income tax audit adjustments proposed by the Arkansas Department of Finance and Administration, an Entergy Wholesale Commodities subsidiary recorded a provision in third quarter 2022 for uncertain tax positions of approximately $21 million, which includes interest expense.

Other Tax Matters

Tax Cuts and Jobs Act (TCJA)

The most significant effect of the TCJA for Entergy and the Registrant Subsidiaries was the change in the federal corporate income tax rate from 35% to 21%, effective January 1, 2018.

TCJA also limited the deduction for net business interest expense to 30 percent of adjusted taxable income, which is similar to earnings before interest, taxes, depreciation, and amortization. The limitation does not apply to interest expense that is properly allocable to a trade or business classified as a regulated public utility. This was further modified by a temporary provision of the CARES Act resulting in an increase of the adjusted taxable income limitation from 30% to 50% for tax years that begin in 2019 or 2020.

The IRS issued final regulations which were effective for Entergy beginning with the 2021 tax year. The regulations provide that if 90% of a tax group’s consolidated assets consist of regulated utility property, the entire consolidated tax group will be treated as a regulated public utility and all of the consolidated group’s interest expense will be currently tax deductible. Entergy expects that its classification as a public utility will continue to apply to its business operations making the application of the interest expense limitation to Entergy unlikely. The provision has not resulted in Entergy having to report any significant business interest expense limitations on its tax returns.

With respect to the federal corporate income tax rate change from 35% to 21% in 2017, Entergy and the Registrant Subsidiaries recorded a regulatory liability associated with the decrease in the net accumulated deferred income tax liability, which is often referred to as “excess ADIT,” a significant portion of which has been paid to customers since 2019 in the form of lower rates. Entergy’s December 31, 2022 and December 31, 2021 balance sheets reflect a regulatory liability of $1.3 billion and $1.3 billion, respectively, as a result of the re-measurement of deferred tax assets and liabilities from the income tax rate change, amortization of excess ADIT, and payments to customers since the enactment of TCJA.
Entergy’s regulatory liability for income taxes includes a gross-up at the applicable tax rate because of the effect that excess ADIT has on the ratemaking formula. The regulatory liability for income taxes includes the effect of a) the reduction of the net deferred tax liability resulting in excess ADIT, and b) the tax gross-up of excess ADIT. The Registrant Subsidiaries’ December 31, 2022 and December 31, 2021 balance sheets reflect net regulatory liabilities for income taxes as follows:
20222021
(In Millions)
Entergy Arkansas$435 $432 
Entergy Louisiana$338 $338 
Entergy Mississippi$202 $212 
Entergy New Orleans$40 $42 
Entergy Texas$133 $171 
System Energy$111 $113 

Excess ADIT is generally classified into two categories: 1) the portion that is subject to the normalization requirements of the TCJA, referred to as “protected”, and 2) the portion that is not subject to such normalization provisions, referred to as “unprotected”. The TCJA provides that the normalization method of accounting for income taxes is required for excess ADIT associated with public utility property. The TCJA provides for the use of the average rate assumption method (ARAM) for the determination of the timing of the return of excess ADIT associated with such property. Under ARAM, the excess ADIT is reduced over the remaining life of the asset. Remaining asset lives vary for each Registrant Subsidiary, but the average life of public utility property is typically 30 years or longer. Entergy will amortize the protected portion of the excess ADIT in conformity with the normalization requirements. The Registrant Subsidiaries’ net regulatory liability for income taxes as of December 31, 2022 and December 31, 2021, includes protected excess ADIT as follows:
20222021
(In Millions)
Entergy Arkansas$453 $463 
Entergy Louisiana$675 $669 
Entergy Mississippi$226 $237 
Entergy New Orleans$53 $56 
Entergy Texas$201 $208 
System Energy$137 $148 

Payment of the unprotected excess accumulated deferred income taxes results in a reduction in the regulatory liability for income taxes and a corresponding reduction in income tax expense. This has a significant effect on the effective tax rate for the period as compared to the statutory tax rate. The Registrant Subsidiaries’ net regulatory liability for income taxes as of December 31, 2022 and December 31, 2021, includes unprotected excess ADIT as follows:
20222021
(In Millions)
Entergy Arkansas$27 $12 
Entergy Louisiana$135 $148 
Entergy Texas$— $26 
The return of unprotected excess accumulated deferred income taxes reduced Entergy’s and the Registrant Subsidiaries’ regulatory liability for income taxes as follows for 2022 and 2021:
20222021
(In Millions)
Entergy$53 $88 
Entergy Arkansas$— $8 
Entergy Louisiana$25 $33 
Entergy New Orleans$1 $1 
Entergy Texas$27 $28 
System Energy$— $18 

In addition to the protected and unprotected excess ADIT amounts, the net regulatory liability for income taxes includes other regulatory assets and liabilities for income taxes associated with AFUDC, which is described in Note 1 to the financial statements.

Included in the effect of the computation of the changes in deferred tax assets and liabilities is the recognition threshold and measurement of uncertain tax positions resulting in unrecognized tax benefits. The final economic outcome of such unrecognized tax benefits is generally the result of a negotiated settlement with the IRS that often differs from the amount that is recorded as realizable under GAAP. The intrinsic uncertainty with respect to all such tax positions means that the difference between current estimates of such amounts likely to be realized and actual amounts realized upon settlement may have an effect on income tax expense and the regulatory liability for income taxes in future periods.

Entergy anticipates that the effect of TCJA may continue to have ramifications that require adjustments in the future as certain events occur. These events include: 1) IRS audit adjustments to or amendments of federal and state income tax returns that include modifications to the computation of taxable income resulting from TCJA; and 2) additional guidance, interpretations, or rulings by the U.S. Department of the Treasury or the IRS. The potential exists for these types of events to result in future tax expense adjustments because of the difference in the federal corporate income tax rate between past and future periods and the effect of the tax rate change on ratemaking. In turn, these events also could potentially affect the regulatory liability for income taxes.

Coronavirus Aid, Relief, and Economic Security Act

In response to the economic impacts of the COVID-19 pandemic, President Trump signed the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) into law on March 27, 2020. The CARES Act provisions that result in the most significant opportunities for tax relief to Entergy and the Registrant Subsidiaries are (i) permitting a five-year carryback of 2018-2020 NOLs, (ii) removing the 80 percent limitation on NOLs carried to tax years beginning before 2021, (iii) increasing the limitation on interest expense deductibility for 2019 and 2020, (iv) accelerating available refunds for minimum tax credit carryforwards, modifying limitations on charitable contributions during 2020, and (v) delaying the payment of employer payroll taxes. Entergy deferred approximately $64 million of 2020 payroll tax payments, payable in equal installments over two years. The initial installment of $32 million was paid in December 2021. The second installment of $32 million was paid in December 2022.

Inflation Reduction Act of 2022

The Inflation Reduction Act of 2022, signed into law on August 16, 2022, significantly expanded federal tax incentives for clean energy production, including the extension of production tax credits to solar projects and certain qualified nuclear power plants. Additionally, the Inflation Reduction Act of 2022 enacted a 1% excise tax on the buyback of public company stock and a new corporate alternative minimum tax. There are no effects on the financial statements as of and for the year ended December 31, 2022 related to the enactment of the law. See the
Income Tax Legislation” section of Entergy Corporation and Subsidiaries Management’s Financial Discussion and Analysis for additional discussion of the effects of the Inflation Reduction Act of 2022.

Entergy Wholesale Commodities Restructuring

In the fourth quarter 2020, Entergy’s ownership of Palisades was restructured. The restructuring required Entergy to recognize Palisades’ nuclear decommissioning liability for income tax purposes resulting in a tax accounting permanent difference that reduced income tax expense, net of unrecognized tax benefits, by $9.2 million. The accrual of the nuclear decommissioning liability also required Entergy to recognize a gain for income tax purposes, a portion of which resulted in an increase in the tax basis of the assets. Recognition of the gain and the increase in the tax basis of the assets represents a tax accounting temporary difference.

Tax Accounting Methods

In the fourth quarter 2015, System Energy and Entergy Louisiana adopted a new method of accounting for income tax return purposes in which their nuclear decommissioning costs will be treated as production costs of electricity includable in cost of goods sold. The new method resulted in a reduction of taxable income of $1.2 billion for System Energy and $2.2 billion for Energy Louisiana.

In conjunction with the 2014-2015 IRS audit discussed above, the IRS issued proposed adjustments concerning the nuclear decommissioning tax position allowing System Energy to include $102 million of its decommissioning liability in cost of goods sold, and Entergy Louisiana to include $221 million of its decommissioning liability in cost of goods sold. Entergy, System Energy, and Entergy Louisiana agreed to the proposed adjustments included in the RAR.

As a result of System Energy being allowed to include part of its decommissioning liability in cost of goods sold, System Energy and Entergy recorded a deferred tax liability of $26 million at the time the matter was agreed upon. System Energy also recorded federal and state taxes payable of $402 million. However, on a consolidated basis, Entergy utilized tax loss carryovers to offset the federal taxable income adjustment and did not record federal taxes payable as a result of the outcome of this uncertain tax position.

As a result of Entergy Louisiana being allowed to include part of its decommissioning liability in cost of goods sold, Entergy Louisiana and Entergy recorded a deferred tax liability of $60 million at the time the matter was agreed upon. Both Entergy Louisiana and Entergy utilized tax loss carryovers to offset the taxable income adjustment and accordingly did not record taxes payable as a result of the outcome of this uncertain tax position.

The partial disallowance of this uncertain tax position to include the decommissioning liability in cost of goods sold resulted in a $1.5 billion decrease in the balance of unrecognized tax benefits related to federal and state taxes for Entergy. Additionally, both System Energy and Entergy Louisiana recorded a reduction to their balances of unrecognized tax benefits for federal and state taxes of $461 million and $1.1 billion, respectively.

Entergy Arkansas adopted the same method of accounting for its nuclear decommissioning costs which resulted in a $1.8 billion reduction in taxable income on its 2018 tax return.

In 2016, Entergy Louisiana elected mark-to-market income tax treatment for various wholesale electric power purchase and sale agreements, including Entergy Louisiana’s contract to purchase electricity from the Vidalia hydroelectric facility and from System Energy under the Unit Power Sales Agreement. The election resulted in a $2.2 billion deductible temporary difference. In 2017, Entergy New Orleans also elected mark-to-market income tax treatment for wholesale electric contracts which resulted in a $1.1 billion deductible temporary difference. In 2018, Entergy Arkansas and Entergy Mississippi accrued deductible temporary differences related to mark-to-market tax accounting for wholesale electric contracts of $2.1 billion and $1.9 billion, respectively. Additionally, in
2020, Entergy Texas elected mark-to-market income tax treatment for wholesale electric power purchase and sale agreements which resulted in a $2.5 billion deductible temporary difference.

Arkansas and Louisiana Corporate Income Tax Rate Changes

In April 2019, December 2021, and August 2022 the State of Arkansas enacted corporate income tax law changes that phased in rate reductions from the former rate of 6.5% to 6.2% in 2021, and 5.9% in 2022.  The August 2022 legislation accelerated the rate reduction to 5.3% for tax years beginning on or after January 1, 2023, accelerating the rate reductions that were originally scheduled to take effect in the 2025 tax year. As a result of the 2019 rate reduction, Entergy Arkansas computed a regulatory liability for income taxes as of December 31, 2020 of approximately $21 million, which includes a tax gross-up related to the treatment of income taxes in the retail and wholesale ratemaking formulas and has been included in the appropriate rate mechanisms. Entergy Arkansas recorded incremental regulatory liabilities of $11 million and $15 million associated with the rate reductions enacted in 2021 and 2022, respectively. The Arkansas tax law enactment also phases in an increase to the net operating loss carryover period from five to ten years.

Pursuant to legislation enacted in 2021 and approved by Louisiana citizens by amendment to the state constitution, beginning January 1, 2022, federal income taxes paid will no longer be deductible for state income tax purposes, and the top Louisiana corporate income tax rate will be reduced from 8% to 7.5%. As a result of this change in Louisiana tax law, the Louisiana applicable tax rate increased by 0.85%. Accordingly, deferred tax assets and liabilities were adjusted to reflect the new applicable federal and state rates. Legislation enacted in 2021 also provides that Louisiana net operating losses generally have an indefinite carryover period.

Entergy recorded a net increase to its deferred tax asset of $27 million. Entergy Louisiana and Entergy New Orleans recorded net increases to their deferred tax liabilities before consideration of the tax gross-up of $77 million and $8 million, respectively, which were offset by regulatory assets for income taxes. Therefore, these increases had no effect on tax expense. However, the increase of deferred tax assets associated with certain assets reduced tax expense for Entergy Louisiana and Entergy New Orleans by $6 million and $2 million, respectively.

Stock Compensation

In accordance with stock compensation accounting rules, Entergy and the Registrant Subsidiaries recognized excess tax deductions as a reduction of income tax expense in the first quarter 2020. Due to the vesting and exercise of certain Entergy stock-based awards, Entergy recorded a permanent tax reduction of approximately $24.7 million, including $4.8 million for Entergy Arkansas, $8.6 million for Entergy Louisiana, $2.7 million for Entergy Mississippi, $1.5 million for Entergy New Orleans, $2.7 million for Entergy Texas, and $1.3 million for System Energy.

Act 293 Securitization

As described in Note 2 to the financial statements, Entergy Louisiana implemented a securitization authorized under Act 293 of the Louisiana legislature. Act 293 provides that the LURC contribute the net bond proceeds to a LURC-sponsored trust. Over the 15-year term of the Act 293 bonds, the storm trust will make distributions to Entergy Louisiana, a beneficiary of the storm trust, that will not be taxable to Entergy Louisiana. Additionally, Entergy Louisiana will not include the receipt of the system restoration charges in taxable income because the right to receive the system restoration charges has been granted directly to the LURC, and Entergy Louisiana only acts as an agent to collect those charges on behalf of the LURC.

Accordingly, the securitization provides for a tax accounting permanent difference resulting in a net reduction of income tax expense in second quarter 2022 of approximately $290 million, after taking into account a provision for uncertain tax positions, by Entergy Louisiana. Entergy’s recognition of reduced income tax expense
was offset by other tax charges resulting in a net reduction of income tax expense of $283 million, after taking into account a provision for uncertain tax positions.

In recognition of its obligations related to an LPSC ancillary order issued as part of the securitization regulatory proceeding, Entergy Louisiana recorded in second quarter 2022 a $224 million ($165 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to share the benefits of the securitization with customers. See Note 2 to the financial statements for discussion of the Entergy Louisiana securitization.

Entergy’s estimated tax attributes carryovers and their expiration dates as of December 31, 2022 are as follows:
Carryover DescriptionCarryover AmountYear(s) of expiration
   
Federal net operating losses before 1/1/2018$6.2 billion2023-2027
Federal net operating losses - 1/1/2018 forward$20.1 billionN/A
State net operating losses$7.7 billion2023-2042
State net operating losses with no expiration$15.7 billionN/A
Other federal and state carryforwards$515.7 million2023-2027
Miscellaneous federal and state credits$90.1 million2023-2042

As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers, tax credit carryovers, and other tax attributes reflected on income tax returns. Entergy evaluates the available positive and negative evidence to estimate whether sufficient future taxable income of the appropriate character will be generated to realize the benefits of existing deferred tax assets. When the evaluation indicates that Entergy will not be able to realize the existing benefits, a valuation allowance is recorded to reduce deferred tax assets to the realizable amount.

Because it is more likely than not that the benefits from certain state net operating losses and other deferred tax assets will not be utilized, valuation allowances totaling $372 million as of December 31, 2022 and $325 million as of December 31, 2021 have been provided on the deferred tax assets related to federal and state jurisdictions in which Entergy does not currently expect to be able to utilize certain separate company tax return attributes, preventing realization of such deferred tax assets. As a result of incurring costs related to Hurricane Ida restoration, certain Utility operating companies are entitled to an accelerated tax deduction which generated a taxable loss in various taxing jurisdictions. This accelerated deduction has impaired the realizability of a limited term carryover tax attribute. Accordingly, the impairment contributed to the activity reflected for the valuation allowance disclosed above.

As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers and tax credit carryovers.

Unrecognized tax benefits

Accounting standards establish a “more-likely-than-not” recognition threshold that must be met before a tax benefit can be recognized in the financial statements.  If a tax deduction is taken on a tax return but does not meet the more-likely-than-not recognition threshold, an increase in income tax liability, above what is payable on the tax return, is required to be recorded.  A reconciliation of Entergy’s beginning and ending amount of unrecognized tax benefits is as follows:

The balances of unrecognized tax benefits include $3,254 million, $2,256 million, and $2,208 million as of December 31, 2022, 2021, and 2020, respectively, which, if recognized, would lower the effective income tax rates.  Because of the effect of deferred tax accounting, the remaining balances of unrecognized tax benefits of $3,140 million, $3,504 million, and $3,491 million as of December 31, 2022, 2021, and 2020, respectively, if disallowed, would not affect the annual effective income tax rate but would accelerate the payment of cash to the taxing authority to an earlier period.

Entergy accrues interest expense, if any, related to unrecognized tax benefits in income tax expense.  Entergy’s December 31, 2022, 2021, and 2020 accrued balance for the possible payment of interest is approximately $50 million, $52 million, and $44 million, respectively. Interest (net-of-tax) of ($2) million, $8 million, and ($4) million was recorded in 2022, 2021, and 2020, respectively.

Income Tax Audits

Entergy and its subsidiaries file U.S. federal and various state income tax returns.  IRS examinations are complete for years before 2016. All state taxing authorities’ examinations are complete for years before 2014. Entergy regularly defends its positions and works with the IRS to resolve audits.  The resolution of audit issues could result in significant changes to the amounts of unrecognized tax benefits in the next twelve months.

2014-2015 IRS Audit

The IRS completed its examination of the 2014 and 2015 tax years and issued its 2014-2015 RAR in November 2020. Entergy agreed to all proposed adjustments contained in the RAR. Entergy and the Registrant Subsidiaries recorded the effects of the adjustments associated with the audit in 2020.

In October 2015 two of Entergy’s Louisiana utilities, Entergy Gulf States Louisiana and Entergy Louisiana, combined their businesses into a legal entity which is identified as Entergy Louisiana herein. The structure of the business combination required Entergy to recognize a gain for income tax purposes which resulted in an increase in the tax basis of the assets for Entergy Louisiana. This resulted in recognition in 2015 of a $334 million permanent difference and income tax benefit, net of the uncertain tax position recorded on the transaction.

Primarily related to resolution of the business combination issues, completion of the 2014-2015 IRS audit in 2020 resulted in a $230 million reduction to deferred income tax expense for Entergy. This reduction to deferred income tax expense includes: Entergy Louisiana reversing its provision for uncertain tax position with respect to the business combination, which resulted in a reduction to deferred income tax expense of $383 million; Entergy Corporation recording an increase to deferred tax expense of $61 million and Entergy Wholesale Commodities recording an increase to deferred tax expense of $105 million from the re-measurement of deferred tax assets associated with the resolved uncertain tax position; and miscellaneous other individually insignificant benefits totaling $13 million.

The completion of the 2014-2015 tax audit also resulted in a $31 million reduction to income tax expense associated with Entergy Louisiana’s method of accounting related to the adoption of tangible property regulations. As a result of the settlement of the tangible property regulation tax position, Entergy Louisiana was required to record a $33 million ($24 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to customers pursuant to a prior regulatory settlement.

Finally, upon completion of the 2014-2015 tax audit, Entergy New Orleans recorded a reduction to income tax expense of $8 million associated with claims for mark-to-market deductions.

In the first quarter 2020, Entergy and the IRS agreed on the treatment of funds received by Entergy Louisiana in conjunction with the Act 55 financing of Hurricane Isaac storm costs, which resulted in a net reduction
of income tax expense of approximately $32 million. As a result of the settlement, the position was partially sustained, and Entergy Louisiana recorded a reduction of income tax expense of approximately $58 million primarily due to the reversal of a provision for uncertain tax positions in excess of the agreed-upon settlement. As a result of the IRS settlement, Entergy Louisiana recorded a $29 million ($21 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to customers pursuant to the LPSC Hurricane Isaac Act 55 financing order.

Additional effects of the completion of the 2014-2015 IRS tax audit are discussed below within Tax Accounting Methods.

State Income Tax Audits

As a result of income tax audit adjustments proposed by the Arkansas Department of Finance and Administration, an Entergy Wholesale Commodities subsidiary recorded a provision in third quarter 2022 for uncertain tax positions of approximately $21 million, which includes interest expense.

Other Tax Matters

Tax Cuts and Jobs Act (TCJA)

The most significant effect of the TCJA for Entergy and the Registrant Subsidiaries was the change in the federal corporate income tax rate from 35% to 21%, effective January 1, 2018.

TCJA also limited the deduction for net business interest expense to 30 percent of adjusted taxable income, which is similar to earnings before interest, taxes, depreciation, and amortization. The limitation does not apply to interest expense that is properly allocable to a trade or business classified as a regulated public utility. This was further modified by a temporary provision of the CARES Act resulting in an increase of the adjusted taxable income limitation from 30% to 50% for tax years that begin in 2019 or 2020.

The IRS issued final regulations which were effective for Entergy beginning with the 2021 tax year. The regulations provide that if 90% of a tax group’s consolidated assets consist of regulated utility property, the entire consolidated tax group will be treated as a regulated public utility and all of the consolidated group’s interest expense will be currently tax deductible. Entergy expects that its classification as a public utility will continue to apply to its business operations making the application of the interest expense limitation to Entergy unlikely. The provision has not resulted in Entergy having to report any significant business interest expense limitations on its tax returns.

With respect to the federal corporate income tax rate change from 35% to 21% in 2017, Entergy and the Registrant Subsidiaries recorded a regulatory liability associated with the decrease in the net accumulated deferred income tax liability, which is often referred to as “excess ADIT,” a significant portion of which has been paid to customers since 2019 in the form of lower rates. Entergy’s December 31, 2022 and December 31, 2021 balance sheets reflect a regulatory liability of $1.3 billion and $1.3 billion, respectively, as a result of the re-measurement of deferred tax assets and liabilities from the income tax rate change, amortization of excess ADIT, and payments to customers since the enactment of TCJA.
Entergy’s regulatory liability for income taxes includes a gross-up at the applicable tax rate because of the effect that excess ADIT has on the ratemaking formula. The regulatory liability for income taxes includes the effect of a) the reduction of the net deferred tax liability resulting in excess ADIT, and b) the tax gross-up of excess ADIT. The Registrant Subsidiaries’ December 31, 2022 and December 31, 2021 balance sheets reflect net regulatory liabilities for income taxes as follows:
20222021
(In Millions)
Entergy Arkansas$435 $432 
Entergy Louisiana$338 $338 
Entergy Mississippi$202 $212 
Entergy New Orleans$40 $42 
Entergy Texas$133 $171 
System Energy$111 $113 

Excess ADIT is generally classified into two categories: 1) the portion that is subject to the normalization requirements of the TCJA, referred to as “protected”, and 2) the portion that is not subject to such normalization provisions, referred to as “unprotected”. The TCJA provides that the normalization method of accounting for income taxes is required for excess ADIT associated with public utility property. The TCJA provides for the use of the average rate assumption method (ARAM) for the determination of the timing of the return of excess ADIT associated with such property. Under ARAM, the excess ADIT is reduced over the remaining life of the asset. Remaining asset lives vary for each Registrant Subsidiary, but the average life of public utility property is typically 30 years or longer. Entergy will amortize the protected portion of the excess ADIT in conformity with the normalization requirements. The Registrant Subsidiaries’ net regulatory liability for income taxes as of December 31, 2022 and December 31, 2021, includes protected excess ADIT as follows:
20222021
(In Millions)
Entergy Arkansas$453 $463 
Entergy Louisiana$675 $669 
Entergy Mississippi$226 $237 
Entergy New Orleans$53 $56 
Entergy Texas$201 $208 
System Energy$137 $148 

Payment of the unprotected excess accumulated deferred income taxes results in a reduction in the regulatory liability for income taxes and a corresponding reduction in income tax expense. This has a significant effect on the effective tax rate for the period as compared to the statutory tax rate. The Registrant Subsidiaries’ net regulatory liability for income taxes as of December 31, 2022 and December 31, 2021, includes unprotected excess ADIT as follows:
20222021
(In Millions)
Entergy Arkansas$27 $12 
Entergy Louisiana$135 $148 
Entergy Texas$— $26 
The return of unprotected excess accumulated deferred income taxes reduced Entergy’s and the Registrant Subsidiaries’ regulatory liability for income taxes as follows for 2022 and 2021:
20222021
(In Millions)
Entergy$53 $88 
Entergy Arkansas$— $8 
Entergy Louisiana$25 $33 
Entergy New Orleans$1 $1 
Entergy Texas$27 $28 
System Energy$— $18 

In addition to the protected and unprotected excess ADIT amounts, the net regulatory liability for income taxes includes other regulatory assets and liabilities for income taxes associated with AFUDC, which is described in Note 1 to the financial statements.

Included in the effect of the computation of the changes in deferred tax assets and liabilities is the recognition threshold and measurement of uncertain tax positions resulting in unrecognized tax benefits. The final economic outcome of such unrecognized tax benefits is generally the result of a negotiated settlement with the IRS that often differs from the amount that is recorded as realizable under GAAP. The intrinsic uncertainty with respect to all such tax positions means that the difference between current estimates of such amounts likely to be realized and actual amounts realized upon settlement may have an effect on income tax expense and the regulatory liability for income taxes in future periods.

Entergy anticipates that the effect of TCJA may continue to have ramifications that require adjustments in the future as certain events occur. These events include: 1) IRS audit adjustments to or amendments of federal and state income tax returns that include modifications to the computation of taxable income resulting from TCJA; and 2) additional guidance, interpretations, or rulings by the U.S. Department of the Treasury or the IRS. The potential exists for these types of events to result in future tax expense adjustments because of the difference in the federal corporate income tax rate between past and future periods and the effect of the tax rate change on ratemaking. In turn, these events also could potentially affect the regulatory liability for income taxes.

Coronavirus Aid, Relief, and Economic Security Act

In response to the economic impacts of the COVID-19 pandemic, President Trump signed the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) into law on March 27, 2020. The CARES Act provisions that result in the most significant opportunities for tax relief to Entergy and the Registrant Subsidiaries are (i) permitting a five-year carryback of 2018-2020 NOLs, (ii) removing the 80 percent limitation on NOLs carried to tax years beginning before 2021, (iii) increasing the limitation on interest expense deductibility for 2019 and 2020, (iv) accelerating available refunds for minimum tax credit carryforwards, modifying limitations on charitable contributions during 2020, and (v) delaying the payment of employer payroll taxes. Entergy deferred approximately $64 million of 2020 payroll tax payments, payable in equal installments over two years. The initial installment of $32 million was paid in December 2021. The second installment of $32 million was paid in December 2022.

Inflation Reduction Act of 2022

The Inflation Reduction Act of 2022, signed into law on August 16, 2022, significantly expanded federal tax incentives for clean energy production, including the extension of production tax credits to solar projects and certain qualified nuclear power plants. Additionally, the Inflation Reduction Act of 2022 enacted a 1% excise tax on the buyback of public company stock and a new corporate alternative minimum tax. There are no effects on the financial statements as of and for the year ended December 31, 2022 related to the enactment of the law. See the
Income Tax Legislation” section of Entergy Corporation and Subsidiaries Management’s Financial Discussion and Analysis for additional discussion of the effects of the Inflation Reduction Act of 2022.

Entergy Wholesale Commodities Restructuring

In the fourth quarter 2020, Entergy’s ownership of Palisades was restructured. The restructuring required Entergy to recognize Palisades’ nuclear decommissioning liability for income tax purposes resulting in a tax accounting permanent difference that reduced income tax expense, net of unrecognized tax benefits, by $9.2 million. The accrual of the nuclear decommissioning liability also required Entergy to recognize a gain for income tax purposes, a portion of which resulted in an increase in the tax basis of the assets. Recognition of the gain and the increase in the tax basis of the assets represents a tax accounting temporary difference.

Tax Accounting Methods

In the fourth quarter 2015, System Energy and Entergy Louisiana adopted a new method of accounting for income tax return purposes in which their nuclear decommissioning costs will be treated as production costs of electricity includable in cost of goods sold. The new method resulted in a reduction of taxable income of $1.2 billion for System Energy and $2.2 billion for Energy Louisiana.

In conjunction with the 2014-2015 IRS audit discussed above, the IRS issued proposed adjustments concerning the nuclear decommissioning tax position allowing System Energy to include $102 million of its decommissioning liability in cost of goods sold, and Entergy Louisiana to include $221 million of its decommissioning liability in cost of goods sold. Entergy, System Energy, and Entergy Louisiana agreed to the proposed adjustments included in the RAR.

As a result of System Energy being allowed to include part of its decommissioning liability in cost of goods sold, System Energy and Entergy recorded a deferred tax liability of $26 million at the time the matter was agreed upon. System Energy also recorded federal and state taxes payable of $402 million. However, on a consolidated basis, Entergy utilized tax loss carryovers to offset the federal taxable income adjustment and did not record federal taxes payable as a result of the outcome of this uncertain tax position.

As a result of Entergy Louisiana being allowed to include part of its decommissioning liability in cost of goods sold, Entergy Louisiana and Entergy recorded a deferred tax liability of $60 million at the time the matter was agreed upon. Both Entergy Louisiana and Entergy utilized tax loss carryovers to offset the taxable income adjustment and accordingly did not record taxes payable as a result of the outcome of this uncertain tax position.

The partial disallowance of this uncertain tax position to include the decommissioning liability in cost of goods sold resulted in a $1.5 billion decrease in the balance of unrecognized tax benefits related to federal and state taxes for Entergy. Additionally, both System Energy and Entergy Louisiana recorded a reduction to their balances of unrecognized tax benefits for federal and state taxes of $461 million and $1.1 billion, respectively.

Entergy Arkansas adopted the same method of accounting for its nuclear decommissioning costs which resulted in a $1.8 billion reduction in taxable income on its 2018 tax return.

In 2016, Entergy Louisiana elected mark-to-market income tax treatment for various wholesale electric power purchase and sale agreements, including Entergy Louisiana’s contract to purchase electricity from the Vidalia hydroelectric facility and from System Energy under the Unit Power Sales Agreement. The election resulted in a $2.2 billion deductible temporary difference. In 2017, Entergy New Orleans also elected mark-to-market income tax treatment for wholesale electric contracts which resulted in a $1.1 billion deductible temporary difference. In 2018, Entergy Arkansas and Entergy Mississippi accrued deductible temporary differences related to mark-to-market tax accounting for wholesale electric contracts of $2.1 billion and $1.9 billion, respectively. Additionally, in
2020, Entergy Texas elected mark-to-market income tax treatment for wholesale electric power purchase and sale agreements which resulted in a $2.5 billion deductible temporary difference.

Arkansas and Louisiana Corporate Income Tax Rate Changes

In April 2019, December 2021, and August 2022 the State of Arkansas enacted corporate income tax law changes that phased in rate reductions from the former rate of 6.5% to 6.2% in 2021, and 5.9% in 2022.  The August 2022 legislation accelerated the rate reduction to 5.3% for tax years beginning on or after January 1, 2023, accelerating the rate reductions that were originally scheduled to take effect in the 2025 tax year. As a result of the 2019 rate reduction, Entergy Arkansas computed a regulatory liability for income taxes as of December 31, 2020 of approximately $21 million, which includes a tax gross-up related to the treatment of income taxes in the retail and wholesale ratemaking formulas and has been included in the appropriate rate mechanisms. Entergy Arkansas recorded incremental regulatory liabilities of $11 million and $15 million associated with the rate reductions enacted in 2021 and 2022, respectively. The Arkansas tax law enactment also phases in an increase to the net operating loss carryover period from five to ten years.

Pursuant to legislation enacted in 2021 and approved by Louisiana citizens by amendment to the state constitution, beginning January 1, 2022, federal income taxes paid will no longer be deductible for state income tax purposes, and the top Louisiana corporate income tax rate will be reduced from 8% to 7.5%. As a result of this change in Louisiana tax law, the Louisiana applicable tax rate increased by 0.85%. Accordingly, deferred tax assets and liabilities were adjusted to reflect the new applicable federal and state rates. Legislation enacted in 2021 also provides that Louisiana net operating losses generally have an indefinite carryover period.

Entergy recorded a net increase to its deferred tax asset of $27 million. Entergy Louisiana and Entergy New Orleans recorded net increases to their deferred tax liabilities before consideration of the tax gross-up of $77 million and $8 million, respectively, which were offset by regulatory assets for income taxes. Therefore, these increases had no effect on tax expense. However, the increase of deferred tax assets associated with certain assets reduced tax expense for Entergy Louisiana and Entergy New Orleans by $6 million and $2 million, respectively.

Stock Compensation

In accordance with stock compensation accounting rules, Entergy and the Registrant Subsidiaries recognized excess tax deductions as a reduction of income tax expense in the first quarter 2020. Due to the vesting and exercise of certain Entergy stock-based awards, Entergy recorded a permanent tax reduction of approximately $24.7 million, including $4.8 million for Entergy Arkansas, $8.6 million for Entergy Louisiana, $2.7 million for Entergy Mississippi, $1.5 million for Entergy New Orleans, $2.7 million for Entergy Texas, and $1.3 million for System Energy.

Act 293 Securitization

As described in Note 2 to the financial statements, Entergy Louisiana implemented a securitization authorized under Act 293 of the Louisiana legislature. Act 293 provides that the LURC contribute the net bond proceeds to a LURC-sponsored trust. Over the 15-year term of the Act 293 bonds, the storm trust will make distributions to Entergy Louisiana, a beneficiary of the storm trust, that will not be taxable to Entergy Louisiana. Additionally, Entergy Louisiana will not include the receipt of the system restoration charges in taxable income because the right to receive the system restoration charges has been granted directly to the LURC, and Entergy Louisiana only acts as an agent to collect those charges on behalf of the LURC.

Accordingly, the securitization provides for a tax accounting permanent difference resulting in a net reduction of income tax expense in second quarter 2022 of approximately $290 million, after taking into account a provision for uncertain tax positions, by Entergy Louisiana. Entergy’s recognition of reduced income tax expense
was offset by other tax charges resulting in a net reduction of income tax expense of $283 million, after taking into account a provision for uncertain tax positions.

In recognition of its obligations related to an LPSC ancillary order issued as part of the securitization regulatory proceeding, Entergy Louisiana recorded in second quarter 2022 a $224 million ($165 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to share the benefits of the securitization with customers. See Note 2 to the financial statements for discussion of the Entergy Louisiana securitization.

Entergy’s estimated tax attributes carryovers and their expiration dates as of December 31, 2022 are as follows:
Carryover DescriptionCarryover AmountYear(s) of expiration
   
Federal net operating losses before 1/1/2018$6.2 billion2023-2027
Federal net operating losses - 1/1/2018 forward$20.1 billionN/A
State net operating losses$7.7 billion2023-2042
State net operating losses with no expiration$15.7 billionN/A
Other federal and state carryforwards$515.7 million2023-2027
Miscellaneous federal and state credits$90.1 million2023-2042

As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers, tax credit carryovers, and other tax attributes reflected on income tax returns. Entergy evaluates the available positive and negative evidence to estimate whether sufficient future taxable income of the appropriate character will be generated to realize the benefits of existing deferred tax assets. When the evaluation indicates that Entergy will not be able to realize the existing benefits, a valuation allowance is recorded to reduce deferred tax assets to the realizable amount.

Because it is more likely than not that the benefits from certain state net operating losses and other deferred tax assets will not be utilized, valuation allowances totaling $372 million as of December 31, 2022 and $325 million as of December 31, 2021 have been provided on the deferred tax assets related to federal and state jurisdictions in which Entergy does not currently expect to be able to utilize certain separate company tax return attributes, preventing realization of such deferred tax assets. As a result of incurring costs related to Hurricane Ida restoration, certain Utility operating companies are entitled to an accelerated tax deduction which generated a taxable loss in various taxing jurisdictions. This accelerated deduction has impaired the realizability of a limited term carryover tax attribute. Accordingly, the impairment contributed to the activity reflected for the valuation allowance disclosed above.

As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers and tax credit carryovers.

Unrecognized tax benefits

Accounting standards establish a “more-likely-than-not” recognition threshold that must be met before a tax benefit can be recognized in the financial statements.  If a tax deduction is taken on a tax return but does not meet the more-likely-than-not recognition threshold, an increase in income tax liability, above what is payable on the tax return, is required to be recorded.  A reconciliation of Entergy’s beginning and ending amount of unrecognized tax benefits is as follows:

The balances of unrecognized tax benefits include $3,254 million, $2,256 million, and $2,208 million as of December 31, 2022, 2021, and 2020, respectively, which, if recognized, would lower the effective income tax rates.  Because of the effect of deferred tax accounting, the remaining balances of unrecognized tax benefits of $3,140 million, $3,504 million, and $3,491 million as of December 31, 2022, 2021, and 2020, respectively, if disallowed, would not affect the annual effective income tax rate but would accelerate the payment of cash to the taxing authority to an earlier period.

Entergy accrues interest expense, if any, related to unrecognized tax benefits in income tax expense.  Entergy’s December 31, 2022, 2021, and 2020 accrued balance for the possible payment of interest is approximately $50 million, $52 million, and $44 million, respectively. Interest (net-of-tax) of ($2) million, $8 million, and ($4) million was recorded in 2022, 2021, and 2020, respectively.

Income Tax Audits

Entergy and its subsidiaries file U.S. federal and various state income tax returns.  IRS examinations are complete for years before 2016. All state taxing authorities’ examinations are complete for years before 2014. Entergy regularly defends its positions and works with the IRS to resolve audits.  The resolution of audit issues could result in significant changes to the amounts of unrecognized tax benefits in the next twelve months.

2014-2015 IRS Audit

The IRS completed its examination of the 2014 and 2015 tax years and issued its 2014-2015 RAR in November 2020. Entergy agreed to all proposed adjustments contained in the RAR. Entergy and the Registrant Subsidiaries recorded the effects of the adjustments associated with the audit in 2020.

In October 2015 two of Entergy’s Louisiana utilities, Entergy Gulf States Louisiana and Entergy Louisiana, combined their businesses into a legal entity which is identified as Entergy Louisiana herein. The structure of the business combination required Entergy to recognize a gain for income tax purposes which resulted in an increase in the tax basis of the assets for Entergy Louisiana. This resulted in recognition in 2015 of a $334 million permanent difference and income tax benefit, net of the uncertain tax position recorded on the transaction.

Primarily related to resolution of the business combination issues, completion of the 2014-2015 IRS audit in 2020 resulted in a $230 million reduction to deferred income tax expense for Entergy. This reduction to deferred income tax expense includes: Entergy Louisiana reversing its provision for uncertain tax position with respect to the business combination, which resulted in a reduction to deferred income tax expense of $383 million; Entergy Corporation recording an increase to deferred tax expense of $61 million and Entergy Wholesale Commodities recording an increase to deferred tax expense of $105 million from the re-measurement of deferred tax assets associated with the resolved uncertain tax position; and miscellaneous other individually insignificant benefits totaling $13 million.

The completion of the 2014-2015 tax audit also resulted in a $31 million reduction to income tax expense associated with Entergy Louisiana’s method of accounting related to the adoption of tangible property regulations. As a result of the settlement of the tangible property regulation tax position, Entergy Louisiana was required to record a $33 million ($24 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to customers pursuant to a prior regulatory settlement.

Finally, upon completion of the 2014-2015 tax audit, Entergy New Orleans recorded a reduction to income tax expense of $8 million associated with claims for mark-to-market deductions.

In the first quarter 2020, Entergy and the IRS agreed on the treatment of funds received by Entergy Louisiana in conjunction with the Act 55 financing of Hurricane Isaac storm costs, which resulted in a net reduction
of income tax expense of approximately $32 million. As a result of the settlement, the position was partially sustained, and Entergy Louisiana recorded a reduction of income tax expense of approximately $58 million primarily due to the reversal of a provision for uncertain tax positions in excess of the agreed-upon settlement. As a result of the IRS settlement, Entergy Louisiana recorded a $29 million ($21 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to customers pursuant to the LPSC Hurricane Isaac Act 55 financing order.

Additional effects of the completion of the 2014-2015 IRS tax audit are discussed below within Tax Accounting Methods.

State Income Tax Audits

As a result of income tax audit adjustments proposed by the Arkansas Department of Finance and Administration, an Entergy Wholesale Commodities subsidiary recorded a provision in third quarter 2022 for uncertain tax positions of approximately $21 million, which includes interest expense.

Other Tax Matters

Tax Cuts and Jobs Act (TCJA)

The most significant effect of the TCJA for Entergy and the Registrant Subsidiaries was the change in the federal corporate income tax rate from 35% to 21%, effective January 1, 2018.

TCJA also limited the deduction for net business interest expense to 30 percent of adjusted taxable income, which is similar to earnings before interest, taxes, depreciation, and amortization. The limitation does not apply to interest expense that is properly allocable to a trade or business classified as a regulated public utility. This was further modified by a temporary provision of the CARES Act resulting in an increase of the adjusted taxable income limitation from 30% to 50% for tax years that begin in 2019 or 2020.

The IRS issued final regulations which were effective for Entergy beginning with the 2021 tax year. The regulations provide that if 90% of a tax group’s consolidated assets consist of regulated utility property, the entire consolidated tax group will be treated as a regulated public utility and all of the consolidated group’s interest expense will be currently tax deductible. Entergy expects that its classification as a public utility will continue to apply to its business operations making the application of the interest expense limitation to Entergy unlikely. The provision has not resulted in Entergy having to report any significant business interest expense limitations on its tax returns.

With respect to the federal corporate income tax rate change from 35% to 21% in 2017, Entergy and the Registrant Subsidiaries recorded a regulatory liability associated with the decrease in the net accumulated deferred income tax liability, which is often referred to as “excess ADIT,” a significant portion of which has been paid to customers since 2019 in the form of lower rates. Entergy’s December 31, 2022 and December 31, 2021 balance sheets reflect a regulatory liability of $1.3 billion and $1.3 billion, respectively, as a result of the re-measurement of deferred tax assets and liabilities from the income tax rate change, amortization of excess ADIT, and payments to customers since the enactment of TCJA.
Entergy’s regulatory liability for income taxes includes a gross-up at the applicable tax rate because of the effect that excess ADIT has on the ratemaking formula. The regulatory liability for income taxes includes the effect of a) the reduction of the net deferred tax liability resulting in excess ADIT, and b) the tax gross-up of excess ADIT. The Registrant Subsidiaries’ December 31, 2022 and December 31, 2021 balance sheets reflect net regulatory liabilities for income taxes as follows:
20222021
(In Millions)
Entergy Arkansas$435 $432 
Entergy Louisiana$338 $338 
Entergy Mississippi$202 $212 
Entergy New Orleans$40 $42 
Entergy Texas$133 $171 
System Energy$111 $113 

Excess ADIT is generally classified into two categories: 1) the portion that is subject to the normalization requirements of the TCJA, referred to as “protected”, and 2) the portion that is not subject to such normalization provisions, referred to as “unprotected”. The TCJA provides that the normalization method of accounting for income taxes is required for excess ADIT associated with public utility property. The TCJA provides for the use of the average rate assumption method (ARAM) for the determination of the timing of the return of excess ADIT associated with such property. Under ARAM, the excess ADIT is reduced over the remaining life of the asset. Remaining asset lives vary for each Registrant Subsidiary, but the average life of public utility property is typically 30 years or longer. Entergy will amortize the protected portion of the excess ADIT in conformity with the normalization requirements. The Registrant Subsidiaries’ net regulatory liability for income taxes as of December 31, 2022 and December 31, 2021, includes protected excess ADIT as follows:
20222021
(In Millions)
Entergy Arkansas$453 $463 
Entergy Louisiana$675 $669 
Entergy Mississippi$226 $237 
Entergy New Orleans$53 $56 
Entergy Texas$201 $208 
System Energy$137 $148 

Payment of the unprotected excess accumulated deferred income taxes results in a reduction in the regulatory liability for income taxes and a corresponding reduction in income tax expense. This has a significant effect on the effective tax rate for the period as compared to the statutory tax rate. The Registrant Subsidiaries’ net regulatory liability for income taxes as of December 31, 2022 and December 31, 2021, includes unprotected excess ADIT as follows:
20222021
(In Millions)
Entergy Arkansas$27 $12 
Entergy Louisiana$135 $148 
Entergy Texas$— $26 
The return of unprotected excess accumulated deferred income taxes reduced Entergy’s and the Registrant Subsidiaries’ regulatory liability for income taxes as follows for 2022 and 2021:
20222021
(In Millions)
Entergy$53 $88 
Entergy Arkansas$— $8 
Entergy Louisiana$25 $33 
Entergy New Orleans$1 $1 
Entergy Texas$27 $28 
System Energy$— $18 

In addition to the protected and unprotected excess ADIT amounts, the net regulatory liability for income taxes includes other regulatory assets and liabilities for income taxes associated with AFUDC, which is described in Note 1 to the financial statements.

Included in the effect of the computation of the changes in deferred tax assets and liabilities is the recognition threshold and measurement of uncertain tax positions resulting in unrecognized tax benefits. The final economic outcome of such unrecognized tax benefits is generally the result of a negotiated settlement with the IRS that often differs from the amount that is recorded as realizable under GAAP. The intrinsic uncertainty with respect to all such tax positions means that the difference between current estimates of such amounts likely to be realized and actual amounts realized upon settlement may have an effect on income tax expense and the regulatory liability for income taxes in future periods.

Entergy anticipates that the effect of TCJA may continue to have ramifications that require adjustments in the future as certain events occur. These events include: 1) IRS audit adjustments to or amendments of federal and state income tax returns that include modifications to the computation of taxable income resulting from TCJA; and 2) additional guidance, interpretations, or rulings by the U.S. Department of the Treasury or the IRS. The potential exists for these types of events to result in future tax expense adjustments because of the difference in the federal corporate income tax rate between past and future periods and the effect of the tax rate change on ratemaking. In turn, these events also could potentially affect the regulatory liability for income taxes.

Coronavirus Aid, Relief, and Economic Security Act

In response to the economic impacts of the COVID-19 pandemic, President Trump signed the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) into law on March 27, 2020. The CARES Act provisions that result in the most significant opportunities for tax relief to Entergy and the Registrant Subsidiaries are (i) permitting a five-year carryback of 2018-2020 NOLs, (ii) removing the 80 percent limitation on NOLs carried to tax years beginning before 2021, (iii) increasing the limitation on interest expense deductibility for 2019 and 2020, (iv) accelerating available refunds for minimum tax credit carryforwards, modifying limitations on charitable contributions during 2020, and (v) delaying the payment of employer payroll taxes. Entergy deferred approximately $64 million of 2020 payroll tax payments, payable in equal installments over two years. The initial installment of $32 million was paid in December 2021. The second installment of $32 million was paid in December 2022.

Inflation Reduction Act of 2022

The Inflation Reduction Act of 2022, signed into law on August 16, 2022, significantly expanded federal tax incentives for clean energy production, including the extension of production tax credits to solar projects and certain qualified nuclear power plants. Additionally, the Inflation Reduction Act of 2022 enacted a 1% excise tax on the buyback of public company stock and a new corporate alternative minimum tax. There are no effects on the financial statements as of and for the year ended December 31, 2022 related to the enactment of the law. See the
Income Tax Legislation” section of Entergy Corporation and Subsidiaries Management’s Financial Discussion and Analysis for additional discussion of the effects of the Inflation Reduction Act of 2022.

Entergy Wholesale Commodities Restructuring

In the fourth quarter 2020, Entergy’s ownership of Palisades was restructured. The restructuring required Entergy to recognize Palisades’ nuclear decommissioning liability for income tax purposes resulting in a tax accounting permanent difference that reduced income tax expense, net of unrecognized tax benefits, by $9.2 million. The accrual of the nuclear decommissioning liability also required Entergy to recognize a gain for income tax purposes, a portion of which resulted in an increase in the tax basis of the assets. Recognition of the gain and the increase in the tax basis of the assets represents a tax accounting temporary difference.

Tax Accounting Methods

In the fourth quarter 2015, System Energy and Entergy Louisiana adopted a new method of accounting for income tax return purposes in which their nuclear decommissioning costs will be treated as production costs of electricity includable in cost of goods sold. The new method resulted in a reduction of taxable income of $1.2 billion for System Energy and $2.2 billion for Energy Louisiana.

In conjunction with the 2014-2015 IRS audit discussed above, the IRS issued proposed adjustments concerning the nuclear decommissioning tax position allowing System Energy to include $102 million of its decommissioning liability in cost of goods sold, and Entergy Louisiana to include $221 million of its decommissioning liability in cost of goods sold. Entergy, System Energy, and Entergy Louisiana agreed to the proposed adjustments included in the RAR.

As a result of System Energy being allowed to include part of its decommissioning liability in cost of goods sold, System Energy and Entergy recorded a deferred tax liability of $26 million at the time the matter was agreed upon. System Energy also recorded federal and state taxes payable of $402 million. However, on a consolidated basis, Entergy utilized tax loss carryovers to offset the federal taxable income adjustment and did not record federal taxes payable as a result of the outcome of this uncertain tax position.

As a result of Entergy Louisiana being allowed to include part of its decommissioning liability in cost of goods sold, Entergy Louisiana and Entergy recorded a deferred tax liability of $60 million at the time the matter was agreed upon. Both Entergy Louisiana and Entergy utilized tax loss carryovers to offset the taxable income adjustment and accordingly did not record taxes payable as a result of the outcome of this uncertain tax position.

The partial disallowance of this uncertain tax position to include the decommissioning liability in cost of goods sold resulted in a $1.5 billion decrease in the balance of unrecognized tax benefits related to federal and state taxes for Entergy. Additionally, both System Energy and Entergy Louisiana recorded a reduction to their balances of unrecognized tax benefits for federal and state taxes of $461 million and $1.1 billion, respectively.

Entergy Arkansas adopted the same method of accounting for its nuclear decommissioning costs which resulted in a $1.8 billion reduction in taxable income on its 2018 tax return.

In 2016, Entergy Louisiana elected mark-to-market income tax treatment for various wholesale electric power purchase and sale agreements, including Entergy Louisiana’s contract to purchase electricity from the Vidalia hydroelectric facility and from System Energy under the Unit Power Sales Agreement. The election resulted in a $2.2 billion deductible temporary difference. In 2017, Entergy New Orleans also elected mark-to-market income tax treatment for wholesale electric contracts which resulted in a $1.1 billion deductible temporary difference. In 2018, Entergy Arkansas and Entergy Mississippi accrued deductible temporary differences related to mark-to-market tax accounting for wholesale electric contracts of $2.1 billion and $1.9 billion, respectively. Additionally, in
2020, Entergy Texas elected mark-to-market income tax treatment for wholesale electric power purchase and sale agreements which resulted in a $2.5 billion deductible temporary difference.

Arkansas and Louisiana Corporate Income Tax Rate Changes

In April 2019, December 2021, and August 2022 the State of Arkansas enacted corporate income tax law changes that phased in rate reductions from the former rate of 6.5% to 6.2% in 2021, and 5.9% in 2022.  The August 2022 legislation accelerated the rate reduction to 5.3% for tax years beginning on or after January 1, 2023, accelerating the rate reductions that were originally scheduled to take effect in the 2025 tax year. As a result of the 2019 rate reduction, Entergy Arkansas computed a regulatory liability for income taxes as of December 31, 2020 of approximately $21 million, which includes a tax gross-up related to the treatment of income taxes in the retail and wholesale ratemaking formulas and has been included in the appropriate rate mechanisms. Entergy Arkansas recorded incremental regulatory liabilities of $11 million and $15 million associated with the rate reductions enacted in 2021 and 2022, respectively. The Arkansas tax law enactment also phases in an increase to the net operating loss carryover period from five to ten years.

Pursuant to legislation enacted in 2021 and approved by Louisiana citizens by amendment to the state constitution, beginning January 1, 2022, federal income taxes paid will no longer be deductible for state income tax purposes, and the top Louisiana corporate income tax rate will be reduced from 8% to 7.5%. As a result of this change in Louisiana tax law, the Louisiana applicable tax rate increased by 0.85%. Accordingly, deferred tax assets and liabilities were adjusted to reflect the new applicable federal and state rates. Legislation enacted in 2021 also provides that Louisiana net operating losses generally have an indefinite carryover period.

Entergy recorded a net increase to its deferred tax asset of $27 million. Entergy Louisiana and Entergy New Orleans recorded net increases to their deferred tax liabilities before consideration of the tax gross-up of $77 million and $8 million, respectively, which were offset by regulatory assets for income taxes. Therefore, these increases had no effect on tax expense. However, the increase of deferred tax assets associated with certain assets reduced tax expense for Entergy Louisiana and Entergy New Orleans by $6 million and $2 million, respectively.

Stock Compensation

In accordance with stock compensation accounting rules, Entergy and the Registrant Subsidiaries recognized excess tax deductions as a reduction of income tax expense in the first quarter 2020. Due to the vesting and exercise of certain Entergy stock-based awards, Entergy recorded a permanent tax reduction of approximately $24.7 million, including $4.8 million for Entergy Arkansas, $8.6 million for Entergy Louisiana, $2.7 million for Entergy Mississippi, $1.5 million for Entergy New Orleans, $2.7 million for Entergy Texas, and $1.3 million for System Energy.

Act 293 Securitization

As described in Note 2 to the financial statements, Entergy Louisiana implemented a securitization authorized under Act 293 of the Louisiana legislature. Act 293 provides that the LURC contribute the net bond proceeds to a LURC-sponsored trust. Over the 15-year term of the Act 293 bonds, the storm trust will make distributions to Entergy Louisiana, a beneficiary of the storm trust, that will not be taxable to Entergy Louisiana. Additionally, Entergy Louisiana will not include the receipt of the system restoration charges in taxable income because the right to receive the system restoration charges has been granted directly to the LURC, and Entergy Louisiana only acts as an agent to collect those charges on behalf of the LURC.

Accordingly, the securitization provides for a tax accounting permanent difference resulting in a net reduction of income tax expense in second quarter 2022 of approximately $290 million, after taking into account a provision for uncertain tax positions, by Entergy Louisiana. Entergy’s recognition of reduced income tax expense
was offset by other tax charges resulting in a net reduction of income tax expense of $283 million, after taking into account a provision for uncertain tax positions.

In recognition of its obligations related to an LPSC ancillary order issued as part of the securitization regulatory proceeding, Entergy Louisiana recorded in second quarter 2022 a $224 million ($165 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to share the benefits of the securitization with customers. See Note 2 to the financial statements for discussion of the Entergy Louisiana securitization.

Entergy’s estimated tax attributes carryovers and their expiration dates as of December 31, 2022 are as follows:
Carryover DescriptionCarryover AmountYear(s) of expiration
   
Federal net operating losses before 1/1/2018$6.2 billion2023-2027
Federal net operating losses - 1/1/2018 forward$20.1 billionN/A
State net operating losses$7.7 billion2023-2042
State net operating losses with no expiration$15.7 billionN/A
Other federal and state carryforwards$515.7 million2023-2027
Miscellaneous federal and state credits$90.1 million2023-2042

As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers, tax credit carryovers, and other tax attributes reflected on income tax returns. Entergy evaluates the available positive and negative evidence to estimate whether sufficient future taxable income of the appropriate character will be generated to realize the benefits of existing deferred tax assets. When the evaluation indicates that Entergy will not be able to realize the existing benefits, a valuation allowance is recorded to reduce deferred tax assets to the realizable amount.

Because it is more likely than not that the benefits from certain state net operating losses and other deferred tax assets will not be utilized, valuation allowances totaling $372 million as of December 31, 2022 and $325 million as of December 31, 2021 have been provided on the deferred tax assets related to federal and state jurisdictions in which Entergy does not currently expect to be able to utilize certain separate company tax return attributes, preventing realization of such deferred tax assets. As a result of incurring costs related to Hurricane Ida restoration, certain Utility operating companies are entitled to an accelerated tax deduction which generated a taxable loss in various taxing jurisdictions. This accelerated deduction has impaired the realizability of a limited term carryover tax attribute. Accordingly, the impairment contributed to the activity reflected for the valuation allowance disclosed above.

As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers and tax credit carryovers.

Unrecognized tax benefits

Accounting standards establish a “more-likely-than-not” recognition threshold that must be met before a tax benefit can be recognized in the financial statements.  If a tax deduction is taken on a tax return but does not meet the more-likely-than-not recognition threshold, an increase in income tax liability, above what is payable on the tax return, is required to be recorded.  A reconciliation of Entergy’s beginning and ending amount of unrecognized tax benefits is as follows:

The balances of unrecognized tax benefits include $3,254 million, $2,256 million, and $2,208 million as of December 31, 2022, 2021, and 2020, respectively, which, if recognized, would lower the effective income tax rates.  Because of the effect of deferred tax accounting, the remaining balances of unrecognized tax benefits of $3,140 million, $3,504 million, and $3,491 million as of December 31, 2022, 2021, and 2020, respectively, if disallowed, would not affect the annual effective income tax rate but would accelerate the payment of cash to the taxing authority to an earlier period.

Entergy accrues interest expense, if any, related to unrecognized tax benefits in income tax expense.  Entergy’s December 31, 2022, 2021, and 2020 accrued balance for the possible payment of interest is approximately $50 million, $52 million, and $44 million, respectively. Interest (net-of-tax) of ($2) million, $8 million, and ($4) million was recorded in 2022, 2021, and 2020, respectively.

Income Tax Audits

Entergy and its subsidiaries file U.S. federal and various state income tax returns.  IRS examinations are complete for years before 2016. All state taxing authorities’ examinations are complete for years before 2014. Entergy regularly defends its positions and works with the IRS to resolve audits.  The resolution of audit issues could result in significant changes to the amounts of unrecognized tax benefits in the next twelve months.

2014-2015 IRS Audit

The IRS completed its examination of the 2014 and 2015 tax years and issued its 2014-2015 RAR in November 2020. Entergy agreed to all proposed adjustments contained in the RAR. Entergy and the Registrant Subsidiaries recorded the effects of the adjustments associated with the audit in 2020.

In October 2015 two of Entergy’s Louisiana utilities, Entergy Gulf States Louisiana and Entergy Louisiana, combined their businesses into a legal entity which is identified as Entergy Louisiana herein. The structure of the business combination required Entergy to recognize a gain for income tax purposes which resulted in an increase in the tax basis of the assets for Entergy Louisiana. This resulted in recognition in 2015 of a $334 million permanent difference and income tax benefit, net of the uncertain tax position recorded on the transaction.

Primarily related to resolution of the business combination issues, completion of the 2014-2015 IRS audit in 2020 resulted in a $230 million reduction to deferred income tax expense for Entergy. This reduction to deferred income tax expense includes: Entergy Louisiana reversing its provision for uncertain tax position with respect to the business combination, which resulted in a reduction to deferred income tax expense of $383 million; Entergy Corporation recording an increase to deferred tax expense of $61 million and Entergy Wholesale Commodities recording an increase to deferred tax expense of $105 million from the re-measurement of deferred tax assets associated with the resolved uncertain tax position; and miscellaneous other individually insignificant benefits totaling $13 million.

The completion of the 2014-2015 tax audit also resulted in a $31 million reduction to income tax expense associated with Entergy Louisiana’s method of accounting related to the adoption of tangible property regulations. As a result of the settlement of the tangible property regulation tax position, Entergy Louisiana was required to record a $33 million ($24 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to customers pursuant to a prior regulatory settlement.

Finally, upon completion of the 2014-2015 tax audit, Entergy New Orleans recorded a reduction to income tax expense of $8 million associated with claims for mark-to-market deductions.

In the first quarter 2020, Entergy and the IRS agreed on the treatment of funds received by Entergy Louisiana in conjunction with the Act 55 financing of Hurricane Isaac storm costs, which resulted in a net reduction
of income tax expense of approximately $32 million. As a result of the settlement, the position was partially sustained, and Entergy Louisiana recorded a reduction of income tax expense of approximately $58 million primarily due to the reversal of a provision for uncertain tax positions in excess of the agreed-upon settlement. As a result of the IRS settlement, Entergy Louisiana recorded a $29 million ($21 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to customers pursuant to the LPSC Hurricane Isaac Act 55 financing order.

Additional effects of the completion of the 2014-2015 IRS tax audit are discussed below within Tax Accounting Methods.

State Income Tax Audits

As a result of income tax audit adjustments proposed by the Arkansas Department of Finance and Administration, an Entergy Wholesale Commodities subsidiary recorded a provision in third quarter 2022 for uncertain tax positions of approximately $21 million, which includes interest expense.

Other Tax Matters

Tax Cuts and Jobs Act (TCJA)

The most significant effect of the TCJA for Entergy and the Registrant Subsidiaries was the change in the federal corporate income tax rate from 35% to 21%, effective January 1, 2018.

TCJA also limited the deduction for net business interest expense to 30 percent of adjusted taxable income, which is similar to earnings before interest, taxes, depreciation, and amortization. The limitation does not apply to interest expense that is properly allocable to a trade or business classified as a regulated public utility. This was further modified by a temporary provision of the CARES Act resulting in an increase of the adjusted taxable income limitation from 30% to 50% for tax years that begin in 2019 or 2020.

The IRS issued final regulations which were effective for Entergy beginning with the 2021 tax year. The regulations provide that if 90% of a tax group’s consolidated assets consist of regulated utility property, the entire consolidated tax group will be treated as a regulated public utility and all of the consolidated group’s interest expense will be currently tax deductible. Entergy expects that its classification as a public utility will continue to apply to its business operations making the application of the interest expense limitation to Entergy unlikely. The provision has not resulted in Entergy having to report any significant business interest expense limitations on its tax returns.

With respect to the federal corporate income tax rate change from 35% to 21% in 2017, Entergy and the Registrant Subsidiaries recorded a regulatory liability associated with the decrease in the net accumulated deferred income tax liability, which is often referred to as “excess ADIT,” a significant portion of which has been paid to customers since 2019 in the form of lower rates. Entergy’s December 31, 2022 and December 31, 2021 balance sheets reflect a regulatory liability of $1.3 billion and $1.3 billion, respectively, as a result of the re-measurement of deferred tax assets and liabilities from the income tax rate change, amortization of excess ADIT, and payments to customers since the enactment of TCJA.
Entergy’s regulatory liability for income taxes includes a gross-up at the applicable tax rate because of the effect that excess ADIT has on the ratemaking formula. The regulatory liability for income taxes includes the effect of a) the reduction of the net deferred tax liability resulting in excess ADIT, and b) the tax gross-up of excess ADIT. The Registrant Subsidiaries’ December 31, 2022 and December 31, 2021 balance sheets reflect net regulatory liabilities for income taxes as follows:
20222021
(In Millions)
Entergy Arkansas$435 $432 
Entergy Louisiana$338 $338 
Entergy Mississippi$202 $212 
Entergy New Orleans$40 $42 
Entergy Texas$133 $171 
System Energy$111 $113 

Excess ADIT is generally classified into two categories: 1) the portion that is subject to the normalization requirements of the TCJA, referred to as “protected”, and 2) the portion that is not subject to such normalization provisions, referred to as “unprotected”. The TCJA provides that the normalization method of accounting for income taxes is required for excess ADIT associated with public utility property. The TCJA provides for the use of the average rate assumption method (ARAM) for the determination of the timing of the return of excess ADIT associated with such property. Under ARAM, the excess ADIT is reduced over the remaining life of the asset. Remaining asset lives vary for each Registrant Subsidiary, but the average life of public utility property is typically 30 years or longer. Entergy will amortize the protected portion of the excess ADIT in conformity with the normalization requirements. The Registrant Subsidiaries’ net regulatory liability for income taxes as of December 31, 2022 and December 31, 2021, includes protected excess ADIT as follows:
20222021
(In Millions)
Entergy Arkansas$453 $463 
Entergy Louisiana$675 $669 
Entergy Mississippi$226 $237 
Entergy New Orleans$53 $56 
Entergy Texas$201 $208 
System Energy$137 $148 

Payment of the unprotected excess accumulated deferred income taxes results in a reduction in the regulatory liability for income taxes and a corresponding reduction in income tax expense. This has a significant effect on the effective tax rate for the period as compared to the statutory tax rate. The Registrant Subsidiaries’ net regulatory liability for income taxes as of December 31, 2022 and December 31, 2021, includes unprotected excess ADIT as follows:
20222021
(In Millions)
Entergy Arkansas$27 $12 
Entergy Louisiana$135 $148 
Entergy Texas$— $26 
The return of unprotected excess accumulated deferred income taxes reduced Entergy’s and the Registrant Subsidiaries’ regulatory liability for income taxes as follows for 2022 and 2021:
20222021
(In Millions)
Entergy$53 $88 
Entergy Arkansas$— $8 
Entergy Louisiana$25 $33 
Entergy New Orleans$1 $1 
Entergy Texas$27 $28 
System Energy$— $18 

In addition to the protected and unprotected excess ADIT amounts, the net regulatory liability for income taxes includes other regulatory assets and liabilities for income taxes associated with AFUDC, which is described in Note 1 to the financial statements.

Included in the effect of the computation of the changes in deferred tax assets and liabilities is the recognition threshold and measurement of uncertain tax positions resulting in unrecognized tax benefits. The final economic outcome of such unrecognized tax benefits is generally the result of a negotiated settlement with the IRS that often differs from the amount that is recorded as realizable under GAAP. The intrinsic uncertainty with respect to all such tax positions means that the difference between current estimates of such amounts likely to be realized and actual amounts realized upon settlement may have an effect on income tax expense and the regulatory liability for income taxes in future periods.

Entergy anticipates that the effect of TCJA may continue to have ramifications that require adjustments in the future as certain events occur. These events include: 1) IRS audit adjustments to or amendments of federal and state income tax returns that include modifications to the computation of taxable income resulting from TCJA; and 2) additional guidance, interpretations, or rulings by the U.S. Department of the Treasury or the IRS. The potential exists for these types of events to result in future tax expense adjustments because of the difference in the federal corporate income tax rate between past and future periods and the effect of the tax rate change on ratemaking. In turn, these events also could potentially affect the regulatory liability for income taxes.

Coronavirus Aid, Relief, and Economic Security Act

In response to the economic impacts of the COVID-19 pandemic, President Trump signed the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) into law on March 27, 2020. The CARES Act provisions that result in the most significant opportunities for tax relief to Entergy and the Registrant Subsidiaries are (i) permitting a five-year carryback of 2018-2020 NOLs, (ii) removing the 80 percent limitation on NOLs carried to tax years beginning before 2021, (iii) increasing the limitation on interest expense deductibility for 2019 and 2020, (iv) accelerating available refunds for minimum tax credit carryforwards, modifying limitations on charitable contributions during 2020, and (v) delaying the payment of employer payroll taxes. Entergy deferred approximately $64 million of 2020 payroll tax payments, payable in equal installments over two years. The initial installment of $32 million was paid in December 2021. The second installment of $32 million was paid in December 2022.

Inflation Reduction Act of 2022

The Inflation Reduction Act of 2022, signed into law on August 16, 2022, significantly expanded federal tax incentives for clean energy production, including the extension of production tax credits to solar projects and certain qualified nuclear power plants. Additionally, the Inflation Reduction Act of 2022 enacted a 1% excise tax on the buyback of public company stock and a new corporate alternative minimum tax. There are no effects on the financial statements as of and for the year ended December 31, 2022 related to the enactment of the law. See the
Income Tax Legislation” section of Entergy Corporation and Subsidiaries Management’s Financial Discussion and Analysis for additional discussion of the effects of the Inflation Reduction Act of 2022.

Entergy Wholesale Commodities Restructuring

In the fourth quarter 2020, Entergy’s ownership of Palisades was restructured. The restructuring required Entergy to recognize Palisades’ nuclear decommissioning liability for income tax purposes resulting in a tax accounting permanent difference that reduced income tax expense, net of unrecognized tax benefits, by $9.2 million. The accrual of the nuclear decommissioning liability also required Entergy to recognize a gain for income tax purposes, a portion of which resulted in an increase in the tax basis of the assets. Recognition of the gain and the increase in the tax basis of the assets represents a tax accounting temporary difference.

Tax Accounting Methods

In the fourth quarter 2015, System Energy and Entergy Louisiana adopted a new method of accounting for income tax return purposes in which their nuclear decommissioning costs will be treated as production costs of electricity includable in cost of goods sold. The new method resulted in a reduction of taxable income of $1.2 billion for System Energy and $2.2 billion for Energy Louisiana.

In conjunction with the 2014-2015 IRS audit discussed above, the IRS issued proposed adjustments concerning the nuclear decommissioning tax position allowing System Energy to include $102 million of its decommissioning liability in cost of goods sold, and Entergy Louisiana to include $221 million of its decommissioning liability in cost of goods sold. Entergy, System Energy, and Entergy Louisiana agreed to the proposed adjustments included in the RAR.

As a result of System Energy being allowed to include part of its decommissioning liability in cost of goods sold, System Energy and Entergy recorded a deferred tax liability of $26 million at the time the matter was agreed upon. System Energy also recorded federal and state taxes payable of $402 million. However, on a consolidated basis, Entergy utilized tax loss carryovers to offset the federal taxable income adjustment and did not record federal taxes payable as a result of the outcome of this uncertain tax position.

As a result of Entergy Louisiana being allowed to include part of its decommissioning liability in cost of goods sold, Entergy Louisiana and Entergy recorded a deferred tax liability of $60 million at the time the matter was agreed upon. Both Entergy Louisiana and Entergy utilized tax loss carryovers to offset the taxable income adjustment and accordingly did not record taxes payable as a result of the outcome of this uncertain tax position.

The partial disallowance of this uncertain tax position to include the decommissioning liability in cost of goods sold resulted in a $1.5 billion decrease in the balance of unrecognized tax benefits related to federal and state taxes for Entergy. Additionally, both System Energy and Entergy Louisiana recorded a reduction to their balances of unrecognized tax benefits for federal and state taxes of $461 million and $1.1 billion, respectively.

Entergy Arkansas adopted the same method of accounting for its nuclear decommissioning costs which resulted in a $1.8 billion reduction in taxable income on its 2018 tax return.

In 2016, Entergy Louisiana elected mark-to-market income tax treatment for various wholesale electric power purchase and sale agreements, including Entergy Louisiana’s contract to purchase electricity from the Vidalia hydroelectric facility and from System Energy under the Unit Power Sales Agreement. The election resulted in a $2.2 billion deductible temporary difference. In 2017, Entergy New Orleans also elected mark-to-market income tax treatment for wholesale electric contracts which resulted in a $1.1 billion deductible temporary difference. In 2018, Entergy Arkansas and Entergy Mississippi accrued deductible temporary differences related to mark-to-market tax accounting for wholesale electric contracts of $2.1 billion and $1.9 billion, respectively. Additionally, in
2020, Entergy Texas elected mark-to-market income tax treatment for wholesale electric power purchase and sale agreements which resulted in a $2.5 billion deductible temporary difference.

Arkansas and Louisiana Corporate Income Tax Rate Changes

In April 2019, December 2021, and August 2022 the State of Arkansas enacted corporate income tax law changes that phased in rate reductions from the former rate of 6.5% to 6.2% in 2021, and 5.9% in 2022.  The August 2022 legislation accelerated the rate reduction to 5.3% for tax years beginning on or after January 1, 2023, accelerating the rate reductions that were originally scheduled to take effect in the 2025 tax year. As a result of the 2019 rate reduction, Entergy Arkansas computed a regulatory liability for income taxes as of December 31, 2020 of approximately $21 million, which includes a tax gross-up related to the treatment of income taxes in the retail and wholesale ratemaking formulas and has been included in the appropriate rate mechanisms. Entergy Arkansas recorded incremental regulatory liabilities of $11 million and $15 million associated with the rate reductions enacted in 2021 and 2022, respectively. The Arkansas tax law enactment also phases in an increase to the net operating loss carryover period from five to ten years.

Pursuant to legislation enacted in 2021 and approved by Louisiana citizens by amendment to the state constitution, beginning January 1, 2022, federal income taxes paid will no longer be deductible for state income tax purposes, and the top Louisiana corporate income tax rate will be reduced from 8% to 7.5%. As a result of this change in Louisiana tax law, the Louisiana applicable tax rate increased by 0.85%. Accordingly, deferred tax assets and liabilities were adjusted to reflect the new applicable federal and state rates. Legislation enacted in 2021 also provides that Louisiana net operating losses generally have an indefinite carryover period.

Entergy recorded a net increase to its deferred tax asset of $27 million. Entergy Louisiana and Entergy New Orleans recorded net increases to their deferred tax liabilities before consideration of the tax gross-up of $77 million and $8 million, respectively, which were offset by regulatory assets for income taxes. Therefore, these increases had no effect on tax expense. However, the increase of deferred tax assets associated with certain assets reduced tax expense for Entergy Louisiana and Entergy New Orleans by $6 million and $2 million, respectively.

Stock Compensation

In accordance with stock compensation accounting rules, Entergy and the Registrant Subsidiaries recognized excess tax deductions as a reduction of income tax expense in the first quarter 2020. Due to the vesting and exercise of certain Entergy stock-based awards, Entergy recorded a permanent tax reduction of approximately $24.7 million, including $4.8 million for Entergy Arkansas, $8.6 million for Entergy Louisiana, $2.7 million for Entergy Mississippi, $1.5 million for Entergy New Orleans, $2.7 million for Entergy Texas, and $1.3 million for System Energy.

Act 293 Securitization

As described in Note 2 to the financial statements, Entergy Louisiana implemented a securitization authorized under Act 293 of the Louisiana legislature. Act 293 provides that the LURC contribute the net bond proceeds to a LURC-sponsored trust. Over the 15-year term of the Act 293 bonds, the storm trust will make distributions to Entergy Louisiana, a beneficiary of the storm trust, that will not be taxable to Entergy Louisiana. Additionally, Entergy Louisiana will not include the receipt of the system restoration charges in taxable income because the right to receive the system restoration charges has been granted directly to the LURC, and Entergy Louisiana only acts as an agent to collect those charges on behalf of the LURC.

Accordingly, the securitization provides for a tax accounting permanent difference resulting in a net reduction of income tax expense in second quarter 2022 of approximately $290 million, after taking into account a provision for uncertain tax positions, by Entergy Louisiana. Entergy’s recognition of reduced income tax expense
was offset by other tax charges resulting in a net reduction of income tax expense of $283 million, after taking into account a provision for uncertain tax positions.

In recognition of its obligations related to an LPSC ancillary order issued as part of the securitization regulatory proceeding, Entergy Louisiana recorded in second quarter 2022 a $224 million ($165 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to share the benefits of the securitization with customers. See Note 2 to the financial statements for discussion of the Entergy Louisiana securitization.

Entergy’s estimated tax attributes carryovers and their expiration dates as of December 31, 2022 are as follows:
Carryover DescriptionCarryover AmountYear(s) of expiration
   
Federal net operating losses before 1/1/2018$6.2 billion2023-2027
Federal net operating losses - 1/1/2018 forward$20.1 billionN/A
State net operating losses$7.7 billion2023-2042
State net operating losses with no expiration$15.7 billionN/A
Other federal and state carryforwards$515.7 million2023-2027
Miscellaneous federal and state credits$90.1 million2023-2042

As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers, tax credit carryovers, and other tax attributes reflected on income tax returns. Entergy evaluates the available positive and negative evidence to estimate whether sufficient future taxable income of the appropriate character will be generated to realize the benefits of existing deferred tax assets. When the evaluation indicates that Entergy will not be able to realize the existing benefits, a valuation allowance is recorded to reduce deferred tax assets to the realizable amount.

Because it is more likely than not that the benefits from certain state net operating losses and other deferred tax assets will not be utilized, valuation allowances totaling $372 million as of December 31, 2022 and $325 million as of December 31, 2021 have been provided on the deferred tax assets related to federal and state jurisdictions in which Entergy does not currently expect to be able to utilize certain separate company tax return attributes, preventing realization of such deferred tax assets. As a result of incurring costs related to Hurricane Ida restoration, certain Utility operating companies are entitled to an accelerated tax deduction which generated a taxable loss in various taxing jurisdictions. This accelerated deduction has impaired the realizability of a limited term carryover tax attribute. Accordingly, the impairment contributed to the activity reflected for the valuation allowance disclosed above.

As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers and tax credit carryovers.

Unrecognized tax benefits

Accounting standards establish a “more-likely-than-not” recognition threshold that must be met before a tax benefit can be recognized in the financial statements.  If a tax deduction is taken on a tax return but does not meet the more-likely-than-not recognition threshold, an increase in income tax liability, above what is payable on the tax return, is required to be recorded.  A reconciliation of Entergy’s beginning and ending amount of unrecognized tax benefits is as follows:

The balances of unrecognized tax benefits include $3,254 million, $2,256 million, and $2,208 million as of December 31, 2022, 2021, and 2020, respectively, which, if recognized, would lower the effective income tax rates.  Because of the effect of deferred tax accounting, the remaining balances of unrecognized tax benefits of $3,140 million, $3,504 million, and $3,491 million as of December 31, 2022, 2021, and 2020, respectively, if disallowed, would not affect the annual effective income tax rate but would accelerate the payment of cash to the taxing authority to an earlier period.

Entergy accrues interest expense, if any, related to unrecognized tax benefits in income tax expense.  Entergy’s December 31, 2022, 2021, and 2020 accrued balance for the possible payment of interest is approximately $50 million, $52 million, and $44 million, respectively. Interest (net-of-tax) of ($2) million, $8 million, and ($4) million was recorded in 2022, 2021, and 2020, respectively.

Income Tax Audits

Entergy and its subsidiaries file U.S. federal and various state income tax returns.  IRS examinations are complete for years before 2016. All state taxing authorities’ examinations are complete for years before 2014. Entergy regularly defends its positions and works with the IRS to resolve audits.  The resolution of audit issues could result in significant changes to the amounts of unrecognized tax benefits in the next twelve months.

2014-2015 IRS Audit

The IRS completed its examination of the 2014 and 2015 tax years and issued its 2014-2015 RAR in November 2020. Entergy agreed to all proposed adjustments contained in the RAR. Entergy and the Registrant Subsidiaries recorded the effects of the adjustments associated with the audit in 2020.

In October 2015 two of Entergy’s Louisiana utilities, Entergy Gulf States Louisiana and Entergy Louisiana, combined their businesses into a legal entity which is identified as Entergy Louisiana herein. The structure of the business combination required Entergy to recognize a gain for income tax purposes which resulted in an increase in the tax basis of the assets for Entergy Louisiana. This resulted in recognition in 2015 of a $334 million permanent difference and income tax benefit, net of the uncertain tax position recorded on the transaction.

Primarily related to resolution of the business combination issues, completion of the 2014-2015 IRS audit in 2020 resulted in a $230 million reduction to deferred income tax expense for Entergy. This reduction to deferred income tax expense includes: Entergy Louisiana reversing its provision for uncertain tax position with respect to the business combination, which resulted in a reduction to deferred income tax expense of $383 million; Entergy Corporation recording an increase to deferred tax expense of $61 million and Entergy Wholesale Commodities recording an increase to deferred tax expense of $105 million from the re-measurement of deferred tax assets associated with the resolved uncertain tax position; and miscellaneous other individually insignificant benefits totaling $13 million.

The completion of the 2014-2015 tax audit also resulted in a $31 million reduction to income tax expense associated with Entergy Louisiana’s method of accounting related to the adoption of tangible property regulations. As a result of the settlement of the tangible property regulation tax position, Entergy Louisiana was required to record a $33 million ($24 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to customers pursuant to a prior regulatory settlement.

Finally, upon completion of the 2014-2015 tax audit, Entergy New Orleans recorded a reduction to income tax expense of $8 million associated with claims for mark-to-market deductions.

In the first quarter 2020, Entergy and the IRS agreed on the treatment of funds received by Entergy Louisiana in conjunction with the Act 55 financing of Hurricane Isaac storm costs, which resulted in a net reduction
of income tax expense of approximately $32 million. As a result of the settlement, the position was partially sustained, and Entergy Louisiana recorded a reduction of income tax expense of approximately $58 million primarily due to the reversal of a provision for uncertain tax positions in excess of the agreed-upon settlement. As a result of the IRS settlement, Entergy Louisiana recorded a $29 million ($21 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to customers pursuant to the LPSC Hurricane Isaac Act 55 financing order.

Additional effects of the completion of the 2014-2015 IRS tax audit are discussed below within Tax Accounting Methods.

State Income Tax Audits

As a result of income tax audit adjustments proposed by the Arkansas Department of Finance and Administration, an Entergy Wholesale Commodities subsidiary recorded a provision in third quarter 2022 for uncertain tax positions of approximately $21 million, which includes interest expense.

Other Tax Matters

Tax Cuts and Jobs Act (TCJA)

The most significant effect of the TCJA for Entergy and the Registrant Subsidiaries was the change in the federal corporate income tax rate from 35% to 21%, effective January 1, 2018.

TCJA also limited the deduction for net business interest expense to 30 percent of adjusted taxable income, which is similar to earnings before interest, taxes, depreciation, and amortization. The limitation does not apply to interest expense that is properly allocable to a trade or business classified as a regulated public utility. This was further modified by a temporary provision of the CARES Act resulting in an increase of the adjusted taxable income limitation from 30% to 50% for tax years that begin in 2019 or 2020.

The IRS issued final regulations which were effective for Entergy beginning with the 2021 tax year. The regulations provide that if 90% of a tax group’s consolidated assets consist of regulated utility property, the entire consolidated tax group will be treated as a regulated public utility and all of the consolidated group’s interest expense will be currently tax deductible. Entergy expects that its classification as a public utility will continue to apply to its business operations making the application of the interest expense limitation to Entergy unlikely. The provision has not resulted in Entergy having to report any significant business interest expense limitations on its tax returns.

With respect to the federal corporate income tax rate change from 35% to 21% in 2017, Entergy and the Registrant Subsidiaries recorded a regulatory liability associated with the decrease in the net accumulated deferred income tax liability, which is often referred to as “excess ADIT,” a significant portion of which has been paid to customers since 2019 in the form of lower rates. Entergy’s December 31, 2022 and December 31, 2021 balance sheets reflect a regulatory liability of $1.3 billion and $1.3 billion, respectively, as a result of the re-measurement of deferred tax assets and liabilities from the income tax rate change, amortization of excess ADIT, and payments to customers since the enactment of TCJA.
Entergy’s regulatory liability for income taxes includes a gross-up at the applicable tax rate because of the effect that excess ADIT has on the ratemaking formula. The regulatory liability for income taxes includes the effect of a) the reduction of the net deferred tax liability resulting in excess ADIT, and b) the tax gross-up of excess ADIT. The Registrant Subsidiaries’ December 31, 2022 and December 31, 2021 balance sheets reflect net regulatory liabilities for income taxes as follows:
20222021
(In Millions)
Entergy Arkansas$435 $432 
Entergy Louisiana$338 $338 
Entergy Mississippi$202 $212 
Entergy New Orleans$40 $42 
Entergy Texas$133 $171 
System Energy$111 $113 

Excess ADIT is generally classified into two categories: 1) the portion that is subject to the normalization requirements of the TCJA, referred to as “protected”, and 2) the portion that is not subject to such normalization provisions, referred to as “unprotected”. The TCJA provides that the normalization method of accounting for income taxes is required for excess ADIT associated with public utility property. The TCJA provides for the use of the average rate assumption method (ARAM) for the determination of the timing of the return of excess ADIT associated with such property. Under ARAM, the excess ADIT is reduced over the remaining life of the asset. Remaining asset lives vary for each Registrant Subsidiary, but the average life of public utility property is typically 30 years or longer. Entergy will amortize the protected portion of the excess ADIT in conformity with the normalization requirements. The Registrant Subsidiaries’ net regulatory liability for income taxes as of December 31, 2022 and December 31, 2021, includes protected excess ADIT as follows:
20222021
(In Millions)
Entergy Arkansas$453 $463 
Entergy Louisiana$675 $669 
Entergy Mississippi$226 $237 
Entergy New Orleans$53 $56 
Entergy Texas$201 $208 
System Energy$137 $148 

Payment of the unprotected excess accumulated deferred income taxes results in a reduction in the regulatory liability for income taxes and a corresponding reduction in income tax expense. This has a significant effect on the effective tax rate for the period as compared to the statutory tax rate. The Registrant Subsidiaries’ net regulatory liability for income taxes as of December 31, 2022 and December 31, 2021, includes unprotected excess ADIT as follows:
20222021
(In Millions)
Entergy Arkansas$27 $12 
Entergy Louisiana$135 $148 
Entergy Texas$— $26 
The return of unprotected excess accumulated deferred income taxes reduced Entergy’s and the Registrant Subsidiaries’ regulatory liability for income taxes as follows for 2022 and 2021:
20222021
(In Millions)
Entergy$53 $88 
Entergy Arkansas$— $8 
Entergy Louisiana$25 $33 
Entergy New Orleans$1 $1 
Entergy Texas$27 $28 
System Energy$— $18 

In addition to the protected and unprotected excess ADIT amounts, the net regulatory liability for income taxes includes other regulatory assets and liabilities for income taxes associated with AFUDC, which is described in Note 1 to the financial statements.

Included in the effect of the computation of the changes in deferred tax assets and liabilities is the recognition threshold and measurement of uncertain tax positions resulting in unrecognized tax benefits. The final economic outcome of such unrecognized tax benefits is generally the result of a negotiated settlement with the IRS that often differs from the amount that is recorded as realizable under GAAP. The intrinsic uncertainty with respect to all such tax positions means that the difference between current estimates of such amounts likely to be realized and actual amounts realized upon settlement may have an effect on income tax expense and the regulatory liability for income taxes in future periods.

Entergy anticipates that the effect of TCJA may continue to have ramifications that require adjustments in the future as certain events occur. These events include: 1) IRS audit adjustments to or amendments of federal and state income tax returns that include modifications to the computation of taxable income resulting from TCJA; and 2) additional guidance, interpretations, or rulings by the U.S. Department of the Treasury or the IRS. The potential exists for these types of events to result in future tax expense adjustments because of the difference in the federal corporate income tax rate between past and future periods and the effect of the tax rate change on ratemaking. In turn, these events also could potentially affect the regulatory liability for income taxes.

Coronavirus Aid, Relief, and Economic Security Act

In response to the economic impacts of the COVID-19 pandemic, President Trump signed the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) into law on March 27, 2020. The CARES Act provisions that result in the most significant opportunities for tax relief to Entergy and the Registrant Subsidiaries are (i) permitting a five-year carryback of 2018-2020 NOLs, (ii) removing the 80 percent limitation on NOLs carried to tax years beginning before 2021, (iii) increasing the limitation on interest expense deductibility for 2019 and 2020, (iv) accelerating available refunds for minimum tax credit carryforwards, modifying limitations on charitable contributions during 2020, and (v) delaying the payment of employer payroll taxes. Entergy deferred approximately $64 million of 2020 payroll tax payments, payable in equal installments over two years. The initial installment of $32 million was paid in December 2021. The second installment of $32 million was paid in December 2022.

Inflation Reduction Act of 2022

The Inflation Reduction Act of 2022, signed into law on August 16, 2022, significantly expanded federal tax incentives for clean energy production, including the extension of production tax credits to solar projects and certain qualified nuclear power plants. Additionally, the Inflation Reduction Act of 2022 enacted a 1% excise tax on the buyback of public company stock and a new corporate alternative minimum tax. There are no effects on the financial statements as of and for the year ended December 31, 2022 related to the enactment of the law. See the
Income Tax Legislation” section of Entergy Corporation and Subsidiaries Management’s Financial Discussion and Analysis for additional discussion of the effects of the Inflation Reduction Act of 2022.

Entergy Wholesale Commodities Restructuring

In the fourth quarter 2020, Entergy’s ownership of Palisades was restructured. The restructuring required Entergy to recognize Palisades’ nuclear decommissioning liability for income tax purposes resulting in a tax accounting permanent difference that reduced income tax expense, net of unrecognized tax benefits, by $9.2 million. The accrual of the nuclear decommissioning liability also required Entergy to recognize a gain for income tax purposes, a portion of which resulted in an increase in the tax basis of the assets. Recognition of the gain and the increase in the tax basis of the assets represents a tax accounting temporary difference.

Tax Accounting Methods

In the fourth quarter 2015, System Energy and Entergy Louisiana adopted a new method of accounting for income tax return purposes in which their nuclear decommissioning costs will be treated as production costs of electricity includable in cost of goods sold. The new method resulted in a reduction of taxable income of $1.2 billion for System Energy and $2.2 billion for Energy Louisiana.

In conjunction with the 2014-2015 IRS audit discussed above, the IRS issued proposed adjustments concerning the nuclear decommissioning tax position allowing System Energy to include $102 million of its decommissioning liability in cost of goods sold, and Entergy Louisiana to include $221 million of its decommissioning liability in cost of goods sold. Entergy, System Energy, and Entergy Louisiana agreed to the proposed adjustments included in the RAR.

As a result of System Energy being allowed to include part of its decommissioning liability in cost of goods sold, System Energy and Entergy recorded a deferred tax liability of $26 million at the time the matter was agreed upon. System Energy also recorded federal and state taxes payable of $402 million. However, on a consolidated basis, Entergy utilized tax loss carryovers to offset the federal taxable income adjustment and did not record federal taxes payable as a result of the outcome of this uncertain tax position.

As a result of Entergy Louisiana being allowed to include part of its decommissioning liability in cost of goods sold, Entergy Louisiana and Entergy recorded a deferred tax liability of $60 million at the time the matter was agreed upon. Both Entergy Louisiana and Entergy utilized tax loss carryovers to offset the taxable income adjustment and accordingly did not record taxes payable as a result of the outcome of this uncertain tax position.

The partial disallowance of this uncertain tax position to include the decommissioning liability in cost of goods sold resulted in a $1.5 billion decrease in the balance of unrecognized tax benefits related to federal and state taxes for Entergy. Additionally, both System Energy and Entergy Louisiana recorded a reduction to their balances of unrecognized tax benefits for federal and state taxes of $461 million and $1.1 billion, respectively.

Entergy Arkansas adopted the same method of accounting for its nuclear decommissioning costs which resulted in a $1.8 billion reduction in taxable income on its 2018 tax return.

In 2016, Entergy Louisiana elected mark-to-market income tax treatment for various wholesale electric power purchase and sale agreements, including Entergy Louisiana’s contract to purchase electricity from the Vidalia hydroelectric facility and from System Energy under the Unit Power Sales Agreement. The election resulted in a $2.2 billion deductible temporary difference. In 2017, Entergy New Orleans also elected mark-to-market income tax treatment for wholesale electric contracts which resulted in a $1.1 billion deductible temporary difference. In 2018, Entergy Arkansas and Entergy Mississippi accrued deductible temporary differences related to mark-to-market tax accounting for wholesale electric contracts of $2.1 billion and $1.9 billion, respectively. Additionally, in
2020, Entergy Texas elected mark-to-market income tax treatment for wholesale electric power purchase and sale agreements which resulted in a $2.5 billion deductible temporary difference.

Arkansas and Louisiana Corporate Income Tax Rate Changes

In April 2019, December 2021, and August 2022 the State of Arkansas enacted corporate income tax law changes that phased in rate reductions from the former rate of 6.5% to 6.2% in 2021, and 5.9% in 2022.  The August 2022 legislation accelerated the rate reduction to 5.3% for tax years beginning on or after January 1, 2023, accelerating the rate reductions that were originally scheduled to take effect in the 2025 tax year. As a result of the 2019 rate reduction, Entergy Arkansas computed a regulatory liability for income taxes as of December 31, 2020 of approximately $21 million, which includes a tax gross-up related to the treatment of income taxes in the retail and wholesale ratemaking formulas and has been included in the appropriate rate mechanisms. Entergy Arkansas recorded incremental regulatory liabilities of $11 million and $15 million associated with the rate reductions enacted in 2021 and 2022, respectively. The Arkansas tax law enactment also phases in an increase to the net operating loss carryover period from five to ten years.

Pursuant to legislation enacted in 2021 and approved by Louisiana citizens by amendment to the state constitution, beginning January 1, 2022, federal income taxes paid will no longer be deductible for state income tax purposes, and the top Louisiana corporate income tax rate will be reduced from 8% to 7.5%. As a result of this change in Louisiana tax law, the Louisiana applicable tax rate increased by 0.85%. Accordingly, deferred tax assets and liabilities were adjusted to reflect the new applicable federal and state rates. Legislation enacted in 2021 also provides that Louisiana net operating losses generally have an indefinite carryover period.

Entergy recorded a net increase to its deferred tax asset of $27 million. Entergy Louisiana and Entergy New Orleans recorded net increases to their deferred tax liabilities before consideration of the tax gross-up of $77 million and $8 million, respectively, which were offset by regulatory assets for income taxes. Therefore, these increases had no effect on tax expense. However, the increase of deferred tax assets associated with certain assets reduced tax expense for Entergy Louisiana and Entergy New Orleans by $6 million and $2 million, respectively.

Stock Compensation

In accordance with stock compensation accounting rules, Entergy and the Registrant Subsidiaries recognized excess tax deductions as a reduction of income tax expense in the first quarter 2020. Due to the vesting and exercise of certain Entergy stock-based awards, Entergy recorded a permanent tax reduction of approximately $24.7 million, including $4.8 million for Entergy Arkansas, $8.6 million for Entergy Louisiana, $2.7 million for Entergy Mississippi, $1.5 million for Entergy New Orleans, $2.7 million for Entergy Texas, and $1.3 million for System Energy.

Act 293 Securitization

As described in Note 2 to the financial statements, Entergy Louisiana implemented a securitization authorized under Act 293 of the Louisiana legislature. Act 293 provides that the LURC contribute the net bond proceeds to a LURC-sponsored trust. Over the 15-year term of the Act 293 bonds, the storm trust will make distributions to Entergy Louisiana, a beneficiary of the storm trust, that will not be taxable to Entergy Louisiana. Additionally, Entergy Louisiana will not include the receipt of the system restoration charges in taxable income because the right to receive the system restoration charges has been granted directly to the LURC, and Entergy Louisiana only acts as an agent to collect those charges on behalf of the LURC.

Accordingly, the securitization provides for a tax accounting permanent difference resulting in a net reduction of income tax expense in second quarter 2022 of approximately $290 million, after taking into account a provision for uncertain tax positions, by Entergy Louisiana. Entergy’s recognition of reduced income tax expense
was offset by other tax charges resulting in a net reduction of income tax expense of $283 million, after taking into account a provision for uncertain tax positions.

In recognition of its obligations related to an LPSC ancillary order issued as part of the securitization regulatory proceeding, Entergy Louisiana recorded in second quarter 2022 a $224 million ($165 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to share the benefits of the securitization with customers. See Note 2 to the financial statements for discussion of the Entergy Louisiana securitization.

Entergy’s estimated tax attributes carryovers and their expiration dates as of December 31, 2022 are as follows:
Carryover DescriptionCarryover AmountYear(s) of expiration
   
Federal net operating losses before 1/1/2018$6.2 billion2023-2027
Federal net operating losses - 1/1/2018 forward$20.1 billionN/A
State net operating losses$7.7 billion2023-2042
State net operating losses with no expiration$15.7 billionN/A
Other federal and state carryforwards$515.7 million2023-2027
Miscellaneous federal and state credits$90.1 million2023-2042

As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers, tax credit carryovers, and other tax attributes reflected on income tax returns. Entergy evaluates the available positive and negative evidence to estimate whether sufficient future taxable income of the appropriate character will be generated to realize the benefits of existing deferred tax assets. When the evaluation indicates that Entergy will not be able to realize the existing benefits, a valuation allowance is recorded to reduce deferred tax assets to the realizable amount.

Because it is more likely than not that the benefits from certain state net operating losses and other deferred tax assets will not be utilized, valuation allowances totaling $372 million as of December 31, 2022 and $325 million as of December 31, 2021 have been provided on the deferred tax assets related to federal and state jurisdictions in which Entergy does not currently expect to be able to utilize certain separate company tax return attributes, preventing realization of such deferred tax assets. As a result of incurring costs related to Hurricane Ida restoration, certain Utility operating companies are entitled to an accelerated tax deduction which generated a taxable loss in various taxing jurisdictions. This accelerated deduction has impaired the realizability of a limited term carryover tax attribute. Accordingly, the impairment contributed to the activity reflected for the valuation allowance disclosed above.

As a result of the accounting for uncertain tax positions, the amount of the deferred tax assets reflected in the financial statements is less than the amount of the tax effect of the federal and state net operating loss carryovers and tax credit carryovers.

Unrecognized tax benefits

Accounting standards establish a “more-likely-than-not” recognition threshold that must be met before a tax benefit can be recognized in the financial statements.  If a tax deduction is taken on a tax return but does not meet the more-likely-than-not recognition threshold, an increase in income tax liability, above what is payable on the tax return, is required to be recorded.  A reconciliation of Entergy’s beginning and ending amount of unrecognized tax benefits is as follows:

The balances of unrecognized tax benefits include $3,254 million, $2,256 million, and $2,208 million as of December 31, 2022, 2021, and 2020, respectively, which, if recognized, would lower the effective income tax rates.  Because of the effect of deferred tax accounting, the remaining balances of unrecognized tax benefits of $3,140 million, $3,504 million, and $3,491 million as of December 31, 2022, 2021, and 2020, respectively, if disallowed, would not affect the annual effective income tax rate but would accelerate the payment of cash to the taxing authority to an earlier period.

Entergy accrues interest expense, if any, related to unrecognized tax benefits in income tax expense.  Entergy’s December 31, 2022, 2021, and 2020 accrued balance for the possible payment of interest is approximately $50 million, $52 million, and $44 million, respectively. Interest (net-of-tax) of ($2) million, $8 million, and ($4) million was recorded in 2022, 2021, and 2020, respectively.

Income Tax Audits

Entergy and its subsidiaries file U.S. federal and various state income tax returns.  IRS examinations are complete for years before 2016. All state taxing authorities’ examinations are complete for years before 2014. Entergy regularly defends its positions and works with the IRS to resolve audits.  The resolution of audit issues could result in significant changes to the amounts of unrecognized tax benefits in the next twelve months.

2014-2015 IRS Audit

The IRS completed its examination of the 2014 and 2015 tax years and issued its 2014-2015 RAR in November 2020. Entergy agreed to all proposed adjustments contained in the RAR. Entergy and the Registrant Subsidiaries recorded the effects of the adjustments associated with the audit in 2020.

In October 2015 two of Entergy’s Louisiana utilities, Entergy Gulf States Louisiana and Entergy Louisiana, combined their businesses into a legal entity which is identified as Entergy Louisiana herein. The structure of the business combination required Entergy to recognize a gain for income tax purposes which resulted in an increase in the tax basis of the assets for Entergy Louisiana. This resulted in recognition in 2015 of a $334 million permanent difference and income tax benefit, net of the uncertain tax position recorded on the transaction.

Primarily related to resolution of the business combination issues, completion of the 2014-2015 IRS audit in 2020 resulted in a $230 million reduction to deferred income tax expense for Entergy. This reduction to deferred income tax expense includes: Entergy Louisiana reversing its provision for uncertain tax position with respect to the business combination, which resulted in a reduction to deferred income tax expense of $383 million; Entergy Corporation recording an increase to deferred tax expense of $61 million and Entergy Wholesale Commodities recording an increase to deferred tax expense of $105 million from the re-measurement of deferred tax assets associated with the resolved uncertain tax position; and miscellaneous other individually insignificant benefits totaling $13 million.

The completion of the 2014-2015 tax audit also resulted in a $31 million reduction to income tax expense associated with Entergy Louisiana’s method of accounting related to the adoption of tangible property regulations. As a result of the settlement of the tangible property regulation tax position, Entergy Louisiana was required to record a $33 million ($24 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to customers pursuant to a prior regulatory settlement.

Finally, upon completion of the 2014-2015 tax audit, Entergy New Orleans recorded a reduction to income tax expense of $8 million associated with claims for mark-to-market deductions.

In the first quarter 2020, Entergy and the IRS agreed on the treatment of funds received by Entergy Louisiana in conjunction with the Act 55 financing of Hurricane Isaac storm costs, which resulted in a net reduction
of income tax expense of approximately $32 million. As a result of the settlement, the position was partially sustained, and Entergy Louisiana recorded a reduction of income tax expense of approximately $58 million primarily due to the reversal of a provision for uncertain tax positions in excess of the agreed-upon settlement. As a result of the IRS settlement, Entergy Louisiana recorded a $29 million ($21 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to customers pursuant to the LPSC Hurricane Isaac Act 55 financing order.

Additional effects of the completion of the 2014-2015 IRS tax audit are discussed below within Tax Accounting Methods.

State Income Tax Audits

As a result of income tax audit adjustments proposed by the Arkansas Department of Finance and Administration, an Entergy Wholesale Commodities subsidiary recorded a provision in third quarter 2022 for uncertain tax positions of approximately $21 million, which includes interest expense.

Other Tax Matters

Tax Cuts and Jobs Act (TCJA)

The most significant effect of the TCJA for Entergy and the Registrant Subsidiaries was the change in the federal corporate income tax rate from 35% to 21%, effective January 1, 2018.

TCJA also limited the deduction for net business interest expense to 30 percent of adjusted taxable income, which is similar to earnings before interest, taxes, depreciation, and amortization. The limitation does not apply to interest expense that is properly allocable to a trade or business classified as a regulated public utility. This was further modified by a temporary provision of the CARES Act resulting in an increase of the adjusted taxable income limitation from 30% to 50% for tax years that begin in 2019 or 2020.

The IRS issued final regulations which were effective for Entergy beginning with the 2021 tax year. The regulations provide that if 90% of a tax group’s consolidated assets consist of regulated utility property, the entire consolidated tax group will be treated as a regulated public utility and all of the consolidated group’s interest expense will be currently tax deductible. Entergy expects that its classification as a public utility will continue to apply to its business operations making the application of the interest expense limitation to Entergy unlikely. The provision has not resulted in Entergy having to report any significant business interest expense limitations on its tax returns.

With respect to the federal corporate income tax rate change from 35% to 21% in 2017, Entergy and the Registrant Subsidiaries recorded a regulatory liability associated with the decrease in the net accumulated deferred income tax liability, which is often referred to as “excess ADIT,” a significant portion of which has been paid to customers since 2019 in the form of lower rates. Entergy’s December 31, 2022 and December 31, 2021 balance sheets reflect a regulatory liability of $1.3 billion and $1.3 billion, respectively, as a result of the re-measurement of deferred tax assets and liabilities from the income tax rate change, amortization of excess ADIT, and payments to customers since the enactment of TCJA.
Entergy’s regulatory liability for income taxes includes a gross-up at the applicable tax rate because of the effect that excess ADIT has on the ratemaking formula. The regulatory liability for income taxes includes the effect of a) the reduction of the net deferred tax liability resulting in excess ADIT, and b) the tax gross-up of excess ADIT. The Registrant Subsidiaries’ December 31, 2022 and December 31, 2021 balance sheets reflect net regulatory liabilities for income taxes as follows:
20222021
(In Millions)
Entergy Arkansas$435 $432 
Entergy Louisiana$338 $338 
Entergy Mississippi$202 $212 
Entergy New Orleans$40 $42 
Entergy Texas$133 $171 
System Energy$111 $113 

Excess ADIT is generally classified into two categories: 1) the portion that is subject to the normalization requirements of the TCJA, referred to as “protected”, and 2) the portion that is not subject to such normalization provisions, referred to as “unprotected”. The TCJA provides that the normalization method of accounting for income taxes is required for excess ADIT associated with public utility property. The TCJA provides for the use of the average rate assumption method (ARAM) for the determination of the timing of the return of excess ADIT associated with such property. Under ARAM, the excess ADIT is reduced over the remaining life of the asset. Remaining asset lives vary for each Registrant Subsidiary, but the average life of public utility property is typically 30 years or longer. Entergy will amortize the protected portion of the excess ADIT in conformity with the normalization requirements. The Registrant Subsidiaries’ net regulatory liability for income taxes as of December 31, 2022 and December 31, 2021, includes protected excess ADIT as follows:
20222021
(In Millions)
Entergy Arkansas$453 $463 
Entergy Louisiana$675 $669 
Entergy Mississippi$226 $237 
Entergy New Orleans$53 $56 
Entergy Texas$201 $208 
System Energy$137 $148 

Payment of the unprotected excess accumulated deferred income taxes results in a reduction in the regulatory liability for income taxes and a corresponding reduction in income tax expense. This has a significant effect on the effective tax rate for the period as compared to the statutory tax rate. The Registrant Subsidiaries’ net regulatory liability for income taxes as of December 31, 2022 and December 31, 2021, includes unprotected excess ADIT as follows:
20222021
(In Millions)
Entergy Arkansas$27 $12 
Entergy Louisiana$135 $148 
Entergy Texas$— $26 
The return of unprotected excess accumulated deferred income taxes reduced Entergy’s and the Registrant Subsidiaries’ regulatory liability for income taxes as follows for 2022 and 2021:
20222021
(In Millions)
Entergy$53 $88 
Entergy Arkansas$— $8 
Entergy Louisiana$25 $33 
Entergy New Orleans$1 $1 
Entergy Texas$27 $28 
System Energy$— $18 

In addition to the protected and unprotected excess ADIT amounts, the net regulatory liability for income taxes includes other regulatory assets and liabilities for income taxes associated with AFUDC, which is described in Note 1 to the financial statements.

Included in the effect of the computation of the changes in deferred tax assets and liabilities is the recognition threshold and measurement of uncertain tax positions resulting in unrecognized tax benefits. The final economic outcome of such unrecognized tax benefits is generally the result of a negotiated settlement with the IRS that often differs from the amount that is recorded as realizable under GAAP. The intrinsic uncertainty with respect to all such tax positions means that the difference between current estimates of such amounts likely to be realized and actual amounts realized upon settlement may have an effect on income tax expense and the regulatory liability for income taxes in future periods.

Entergy anticipates that the effect of TCJA may continue to have ramifications that require adjustments in the future as certain events occur. These events include: 1) IRS audit adjustments to or amendments of federal and state income tax returns that include modifications to the computation of taxable income resulting from TCJA; and 2) additional guidance, interpretations, or rulings by the U.S. Department of the Treasury or the IRS. The potential exists for these types of events to result in future tax expense adjustments because of the difference in the federal corporate income tax rate between past and future periods and the effect of the tax rate change on ratemaking. In turn, these events also could potentially affect the regulatory liability for income taxes.

Coronavirus Aid, Relief, and Economic Security Act

In response to the economic impacts of the COVID-19 pandemic, President Trump signed the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) into law on March 27, 2020. The CARES Act provisions that result in the most significant opportunities for tax relief to Entergy and the Registrant Subsidiaries are (i) permitting a five-year carryback of 2018-2020 NOLs, (ii) removing the 80 percent limitation on NOLs carried to tax years beginning before 2021, (iii) increasing the limitation on interest expense deductibility for 2019 and 2020, (iv) accelerating available refunds for minimum tax credit carryforwards, modifying limitations on charitable contributions during 2020, and (v) delaying the payment of employer payroll taxes. Entergy deferred approximately $64 million of 2020 payroll tax payments, payable in equal installments over two years. The initial installment of $32 million was paid in December 2021. The second installment of $32 million was paid in December 2022.

Inflation Reduction Act of 2022

The Inflation Reduction Act of 2022, signed into law on August 16, 2022, significantly expanded federal tax incentives for clean energy production, including the extension of production tax credits to solar projects and certain qualified nuclear power plants. Additionally, the Inflation Reduction Act of 2022 enacted a 1% excise tax on the buyback of public company stock and a new corporate alternative minimum tax. There are no effects on the financial statements as of and for the year ended December 31, 2022 related to the enactment of the law. See the
Income Tax Legislation” section of Entergy Corporation and Subsidiaries Management’s Financial Discussion and Analysis for additional discussion of the effects of the Inflation Reduction Act of 2022.

Entergy Wholesale Commodities Restructuring

In the fourth quarter 2020, Entergy’s ownership of Palisades was restructured. The restructuring required Entergy to recognize Palisades’ nuclear decommissioning liability for income tax purposes resulting in a tax accounting permanent difference that reduced income tax expense, net of unrecognized tax benefits, by $9.2 million. The accrual of the nuclear decommissioning liability also required Entergy to recognize a gain for income tax purposes, a portion of which resulted in an increase in the tax basis of the assets. Recognition of the gain and the increase in the tax basis of the assets represents a tax accounting temporary difference.

Tax Accounting Methods

In the fourth quarter 2015, System Energy and Entergy Louisiana adopted a new method of accounting for income tax return purposes in which their nuclear decommissioning costs will be treated as production costs of electricity includable in cost of goods sold. The new method resulted in a reduction of taxable income of $1.2 billion for System Energy and $2.2 billion for Energy Louisiana.

In conjunction with the 2014-2015 IRS audit discussed above, the IRS issued proposed adjustments concerning the nuclear decommissioning tax position allowing System Energy to include $102 million of its decommissioning liability in cost of goods sold, and Entergy Louisiana to include $221 million of its decommissioning liability in cost of goods sold. Entergy, System Energy, and Entergy Louisiana agreed to the proposed adjustments included in the RAR.

As a result of System Energy being allowed to include part of its decommissioning liability in cost of goods sold, System Energy and Entergy recorded a deferred tax liability of $26 million at the time the matter was agreed upon. System Energy also recorded federal and state taxes payable of $402 million. However, on a consolidated basis, Entergy utilized tax loss carryovers to offset the federal taxable income adjustment and did not record federal taxes payable as a result of the outcome of this uncertain tax position.

As a result of Entergy Louisiana being allowed to include part of its decommissioning liability in cost of goods sold, Entergy Louisiana and Entergy recorded a deferred tax liability of $60 million at the time the matter was agreed upon. Both Entergy Louisiana and Entergy utilized tax loss carryovers to offset the taxable income adjustment and accordingly did not record taxes payable as a result of the outcome of this uncertain tax position.

The partial disallowance of this uncertain tax position to include the decommissioning liability in cost of goods sold resulted in a $1.5 billion decrease in the balance of unrecognized tax benefits related to federal and state taxes for Entergy. Additionally, both System Energy and Entergy Louisiana recorded a reduction to their balances of unrecognized tax benefits for federal and state taxes of $461 million and $1.1 billion, respectively.

Entergy Arkansas adopted the same method of accounting for its nuclear decommissioning costs which resulted in a $1.8 billion reduction in taxable income on its 2018 tax return.

In 2016, Entergy Louisiana elected mark-to-market income tax treatment for various wholesale electric power purchase and sale agreements, including Entergy Louisiana’s contract to purchase electricity from the Vidalia hydroelectric facility and from System Energy under the Unit Power Sales Agreement. The election resulted in a $2.2 billion deductible temporary difference. In 2017, Entergy New Orleans also elected mark-to-market income tax treatment for wholesale electric contracts which resulted in a $1.1 billion deductible temporary difference. In 2018, Entergy Arkansas and Entergy Mississippi accrued deductible temporary differences related to mark-to-market tax accounting for wholesale electric contracts of $2.1 billion and $1.9 billion, respectively. Additionally, in
2020, Entergy Texas elected mark-to-market income tax treatment for wholesale electric power purchase and sale agreements which resulted in a $2.5 billion deductible temporary difference.

Arkansas and Louisiana Corporate Income Tax Rate Changes

In April 2019, December 2021, and August 2022 the State of Arkansas enacted corporate income tax law changes that phased in rate reductions from the former rate of 6.5% to 6.2% in 2021, and 5.9% in 2022.  The August 2022 legislation accelerated the rate reduction to 5.3% for tax years beginning on or after January 1, 2023, accelerating the rate reductions that were originally scheduled to take effect in the 2025 tax year. As a result of the 2019 rate reduction, Entergy Arkansas computed a regulatory liability for income taxes as of December 31, 2020 of approximately $21 million, which includes a tax gross-up related to the treatment of income taxes in the retail and wholesale ratemaking formulas and has been included in the appropriate rate mechanisms. Entergy Arkansas recorded incremental regulatory liabilities of $11 million and $15 million associated with the rate reductions enacted in 2021 and 2022, respectively. The Arkansas tax law enactment also phases in an increase to the net operating loss carryover period from five to ten years.

Pursuant to legislation enacted in 2021 and approved by Louisiana citizens by amendment to the state constitution, beginning January 1, 2022, federal income taxes paid will no longer be deductible for state income tax purposes, and the top Louisiana corporate income tax rate will be reduced from 8% to 7.5%. As a result of this change in Louisiana tax law, the Louisiana applicable tax rate increased by 0.85%. Accordingly, deferred tax assets and liabilities were adjusted to reflect the new applicable federal and state rates. Legislation enacted in 2021 also provides that Louisiana net operating losses generally have an indefinite carryover period.

Entergy recorded a net increase to its deferred tax asset of $27 million. Entergy Louisiana and Entergy New Orleans recorded net increases to their deferred tax liabilities before consideration of the tax gross-up of $77 million and $8 million, respectively, which were offset by regulatory assets for income taxes. Therefore, these increases had no effect on tax expense. However, the increase of deferred tax assets associated with certain assets reduced tax expense for Entergy Louisiana and Entergy New Orleans by $6 million and $2 million, respectively.

Stock Compensation

In accordance with stock compensation accounting rules, Entergy and the Registrant Subsidiaries recognized excess tax deductions as a reduction of income tax expense in the first quarter 2020. Due to the vesting and exercise of certain Entergy stock-based awards, Entergy recorded a permanent tax reduction of approximately $24.7 million, including $4.8 million for Entergy Arkansas, $8.6 million for Entergy Louisiana, $2.7 million for Entergy Mississippi, $1.5 million for Entergy New Orleans, $2.7 million for Entergy Texas, and $1.3 million for System Energy.

Act 293 Securitization

As described in Note 2 to the financial statements, Entergy Louisiana implemented a securitization authorized under Act 293 of the Louisiana legislature. Act 293 provides that the LURC contribute the net bond proceeds to a LURC-sponsored trust. Over the 15-year term of the Act 293 bonds, the storm trust will make distributions to Entergy Louisiana, a beneficiary of the storm trust, that will not be taxable to Entergy Louisiana. Additionally, Entergy Louisiana will not include the receipt of the system restoration charges in taxable income because the right to receive the system restoration charges has been granted directly to the LURC, and Entergy Louisiana only acts as an agent to collect those charges on behalf of the LURC.

Accordingly, the securitization provides for a tax accounting permanent difference resulting in a net reduction of income tax expense in second quarter 2022 of approximately $290 million, after taking into account a provision for uncertain tax positions, by Entergy Louisiana. Entergy’s recognition of reduced income tax expense
was offset by other tax charges resulting in a net reduction of income tax expense of $283 million, after taking into account a provision for uncertain tax positions.

In recognition of its obligations related to an LPSC ancillary order issued as part of the securitization regulatory proceeding, Entergy Louisiana recorded in second quarter 2022 a $224 million ($165 million net-of-tax) regulatory charge and a corresponding regulatory liability to reflect its obligation to share the benefits of the securitization with customers. See Note 2 to the financial statements for discussion of the Entergy Louisiana securitization.
