INCOME TAXES

The provision for income taxes for continuing operations for the years ended December 31, 2021, 2020 and 2019 consisted of the following:

	Years Ended December 31,
	2021		2020		2019
Current tax expense (benefit):
Federal	$	50	$	—	$	(6)
State	111		30		26
	161		30		20
Deferred tax expense (benefit):

State	(17)		4		—
	250		(127)		140
	$	411	$	(97)	$	160

A reconciliation between the amount of reported income tax expense (benefit) and the amount computed by multiplying income from continuing operations before income taxes by the statutory federal income tax rate is shown below. State income tax expense for the year ended December 31, 2021 includes $2 million of expense related to the write‑off of expired or worthless unutilized state net operating loss carryforwards and other deferred tax assets for which a full valuation allowance had been provided in prior years. A corresponding tax benefit of $2 million is included for the year ended December 31, 2021 to reflect the reduction in the valuation allowance. Foreign pre-tax loss was $5 million for the year ended December 31, 2021, $13 million for the year ended December 31, 2020, and $6 million for the year ended December 31, 2019.

The COVID Acts included a significant number of tax provisions applicable to individuals and businesses. For businesses, the COVID Acts made changes to the U.S. tax code relating to, among other things: (1) the business interest expense disallowance rules for 2019 and 2020; (2) net operating loss rules; (3) charitable contribution limitations; and (4) the realization of corporate alternative minimum tax credits. As a result of the change in the business interest expense disallowance rules, we recorded an income tax benefit of $88 million during the year ended December 31, 2020 to decrease the valuation allowance for interest expense carryforwards due to the additional deduction of interest expense.

In September 2020, we filed an application with the Internal Revenue Service (“IRS”) to change our method of accounting for certain capitalized costs on our 2019 tax return. This change in tax accounting method resulted in additional interest expense being allowed on the 2019 and 2020 tax returns. We reduced our valuation allowance by an additional $126 million in the year ended December 31, 2020 related to the change in accounting method.

Deferred income taxes reflect the tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amount used for income tax purposes. The following table discloses those significant components of our deferred tax assets and liabilities, including any valuation allowance:

	December 31, 2021				December 31, 2020

Below is a reconciliation of the deferred tax assets and liabilities and the corresponding amounts reported in the accompanying Consolidated Balance Sheets.

Deferred income tax assets	$	65	$	325
Deferred tax liabilities	(36)		(29)
Net deferred tax asset	$	29	$	296

During the year ended December 31, 2021, the valuation allowance increased by $2 million, including an increase of $2 million due to limitations on the tax deductibility of interest expense, a decrease of $2 million due to the expiration or worthlessness of unutilized state net operating loss carryovers, and an increase of $2 million due to changes in expected realizability of deferred tax assets. The balance in the valuation allowance as of December 31, 2021 was $57 million. During the year ended December 31, 2020, the valuation allowance decreased by $226 million, including a decrease of $211 million due to limitations on the tax deductibility of interest expense, a decrease of $1 million due to the expiration or worthlessness of unutilized state net operating loss carryovers, and a decrease of $14 million due to changes in expected realizability of deferred tax assets. The remaining balance in the valuation allowance at December 31, 2020 was $55 million. During the year ended December 31, 2019, the valuation allowance increased by $133 million, including an increase of $130 million due to limitations on the tax deductibility of interest expense, a decrease of $2 million due to the expiration or worthlessness of unutilized state net operating loss carryovers, and an increase of $5 million due to changes in expected realizability of deferred tax assets. The remaining balance in the valuation allowance as of December 31, 2019 was $281 million. Deferred tax assets relating to interest expense limitations under Internal Revenue Code Section 163(j) have a full valuation allowance because the interest expense carryovers are not expected to be utilized in the foreseeable future.

We account for uncertain tax positions in accordance with FASB ASC 740-10-25, which prescribes a comprehensive model for the financial statement recognition, measurement, presentation and disclosure of uncertain tax positions taken or expected to be taken in income tax returns. The following table summarizes the total changes in unrecognized tax benefits in continuing operations during the years ended December 31, 2021, 2020 and 2019. There were no such changes in discontinued operations. The additions and reductions for tax positions include the impact of items for which the ultimate deductibility is

highly certain, but for which there is uncertainty about the timing of such deductions. Such amounts include unrecognized tax benefits that have impacted deferred tax assets and liabilities at December 31, 2021, 2020 and 2019.

	Continuing Operations
Balance At December 31, 2018	$	45
Reductions due to a lapse of statute of limitations	(14)
Balance At December 31, 2019	$	31
Reductions due to a lapse of statute of limitations	—
Balance At December 31, 2020	$	31
Increases due to tax positions taken in prior periods	3
Balance At December 31, 2021	$	34

The total amount of unrecognized tax benefits as of December 31, 2021 was $34 million, of which $32 million, if recognized, would affect our effective tax rate and income tax benefit from continuing operations. Income tax expense in the year ended December 31, 2021 included expense of $3 million in continuing operations attributable to an increase in our estimated liabilities for uncertain tax positions, net of related deferred tax effects. The total amount of unrecognized tax benefits as of December 31, 2020 was $31 million, of which $29 million, if recognized, would affect our effective tax rate and income tax benefit from continuing operations. In the year ended December 31, 2020, there was no change in our estimated liabilities for uncertain tax positions. The total amount of unrecognized tax benefits as of December 31, 2019 was $31 million, of which $29 million, if recognized, would affect our effective tax rate and income tax expense from continuing operations. Income tax expense in the year ended December 31, 2019 included a benefit of $11 million in continuing operations attributable to a decrease in our estimated liabilities for uncertain tax positions, net of related deferred tax effects.

Our practice is to recognize interest and penalties related to income tax matters in income tax expense in our consolidated statements of operations. We did not have any interest or penalties on unrecognized tax benefits accrued at December 31, 2021.

The IRS has completed audits of our tax returns for all tax years ended on or before December 31, 2007. All disputed issues with respect to these audits have been resolved and all related tax assessments (including interest) have been paid. Our tax returns for years ended after December 31, 2007 and USPI’s tax returns for years ended after December 31, 2017 remain subject to audit by the IRS.

As of December 31, 2021, no significant changes in unrecognized federal and state tax benefits are expected in the next 12 months as a result of the settlement of audits, the filing of amended tax returns or the expiration of statutes of limitations.

At December 31, 2021, our carryforwards available to offset future taxable income consisted of (1) federal net operating loss (“NOL”) carryforwards of approximately $194 million pre‑tax, $13 million of which expires in 2026 to 2036 and $181 million of which has no expiration date, (2) general business credit carryforwards of approximately $9 million expiring in 2034 through 2038, (3) charitable contribution carryforwards of approximately $90 million expiring in 2024 through 2025 and (4) state NOL carryforwards of approximately $3.333 billion expiring in 2022 through 2041 for which the associated deferred tax benefit, net of valuation allowance and federal tax impact, is $49 million. Our ability to utilize NOL carryforwards to reduce future taxable income may be limited under Section 382 of the Internal Revenue Code if certain ownership changes in our company occur during a rolling three‑year period. These ownership changes include purchases of common stock under share repurchase programs, the offering of stock by us, the purchase or sale of our stock by 5% shareholders, as defined in the Treasury regulations, or the issuance or exercise of rights to acquire our stock. If such ownership changes by 5% shareholders result in aggregate increases that exceed 50 percentage points during the three‑year period, then Section 382 imposes an annual limitation on the amount of our taxable income that may be offset by the NOL carryforwards or tax credit carryforwards at the time of ownership change.
