Income Tax Disclosure [Abstract]
INCOME TAXES	11. INCOME TAXES ASC Topic 740, Income Taxes requires the use of an estimated annual effective tax rate for purposes of determining the income tax provision during interim reporting periods. In calculating its estimated annual effective tax rate, NJR considers forecasted annual pre-tax income and estimated permanent book versus tax differences, as well as investment tax credits associated with solar asset investment. For investment tax credits, the estimate is based on solar projects that are probable of being completed and placed in service during the current fiscal year based on the best information available at each reporting period. Adjustments to the effective tax rate and management's estimates will occur as information and assumptions change. Changes in tax laws or tax rates are recognized in the financial reporting period that includes the enactment date, the date in which the act is signed into law. In May 2019, the Company received a favorable ruling from the IRS regarding a change to its tax method of accounting for the capitalization of certain costs associated with self-constructed property placed in service during fiscal years prior to September 30, 2016. The self-constructed property to which these costs relate is considered qualified energy property as defined under the Internal Revenue Code. As such, the Company is eligible to claim a 30 percent ITC on the increase in the depreciable cost basis of the property through the filing of an amended tax return in the year of change. As a result of the favorable IRS ruling, in June 2019, the Company recorded a benefit from income taxes of approximately $10 million from the additional ITC recognized, net of deferred taxes. NJR evaluates its tax positions to determine the appropriate accounting and recognition of potential future obligations associated with unrecognized tax benefits. A tax benefit claimed, or expected to be claimed, on a tax return may be recognized if it is more likely than not that the position will be upheld upon examination by the applicable taxing authority. Interest and penalties related to unrecognized tax benefits, if any, are recognized within income tax expense and accrued interest, and penalties are recognized within other noncurrent liabilities on the Unaudited Condensed Consolidated Balance Sheets. As of June 30, 2020, the Company had a reserve of $4.9 million for a portion of tax benefits that are uncertain at this time, which is included in deferred income taxes on the Unaudited Condensed Consolidated Balance Sheets. The tax benefits relate to fiscal tax years open to examination by the IRS and may be subject to subsequent adjustment. As of June 30, 2019, there were no reserves associated with uncertain tax positions. Effective Tax Rate The forecasted effective tax rates were (1.2) percent and (4.6) percent, for the nine months ended June 30, 2020 and 2019, respectively. The increase in the effective tax rate, when compared with the prior fiscal year, is due primarily to a combination of an increase in forecasted pre-tax income and a decrease in forecasted tax credits for the fiscal year ending September 30, 2020. Forecasted tax credits, net of deferred income taxes, were $37.5 million and $46.3 million for fiscal 2020 and 2019, respectively. To the extent there are discrete tax items that are not included in the forecasted effective tax rate, the actual effective tax rate will differ from the estimated annual effective tax rate. During the nine months ended June 30, 2020 and 2019, discrete items totaled $2.3 million and $5.4 million, respectively, related to a revaluation of certain state deferred tax assets and liabilities as a result of a change in the New Jersey state apportionment factor and excess tax benefits associated with the vesting of share-based awards. NJR’s actual effective tax rate was (2.8) percent and (8.5) percent during the nine months ended June 30, 2020 and 2019, respectively. CARES Act On March 27, 2020, the President of the United States signed the CARES Act, which is aimed at providing emergency assistance and health care for individuals, families, and businesses affected by the COVID-19 pandemic and generally supporting the U.S. economy. The CARES Act, among other things, includes several business tax provisions which include, but are not limited to modifications of federal net operating loss carrybacks and deductibility, changes to prior year refundable alternative minimum tax liabilities, increase of limitations on business interest deductions from 30 percent to 50 percent of earnings before interest, taxes, depreciation, and amortization, technical corrections of the classification of qualified improvement property making them eligible for bonus depreciation, increase of the limits on charitable contribution deductions from 10 percent to 25 percent of adjusted taxable income, modifications of the treatment of federal loans, loan guarantees, and other investments, suspension of industry specific excise taxes, deferral of the company portion of OASDI, and implementation of a refundable employee retention tax credit. The CARES Act provides for the delay in the required deposit of the employer portion of the OASDI payroll tax from the date of enactment through the end of 2020. Of the taxes that the Company can defer, 50 percent of the deferred taxes are required to be deposited by the end of 2021 and the remaining 50 percent are required to be deposited by the end of 2022. Additionally, The CARES Act provides a refundable tax credit, the employee retention tax credit, to certain employers who are ordered by a competent governmental authority to suspend or reduce business operations due to concern about the spread of COVID-19 or suffered a significant decline in the business during a calendar quarter during 2020 compared to the same calendar quarter during the previous year. As of June 30, 2020, the Company deferred $1.3 million related to the employer portion of the OASDI tax. The Company is currently investigating the applicability of the Employee Retention Tax credit. Other Tax Items As of June 30, 2020 and September 30, 2019, the Company had ITC carryforwards of approximately $184.7 million and $154.2 million, respectively, which each have a life of 20 years. When the Company carries back the federal net operating losses noted below, it expects to recapture investment tax credits totaling $24.1 million. These recaptured tax credits are in addition to the $184.7 million noted above and will be carried forward to offset future taxable income. The Company expects to utilize this entire carryforward, which would begin to expire in fiscal 2034. The Company had federal income tax net operating losses of approximately $134 million as of June 30, 2020 and September 30, 2019, respectively. Federal net operating losses incurred before the implementation of the Tax Act can generally be carried back two years and forward 20 years and will begin to expire in fiscal 2036, with the remainder expiring by 2038. The Company expects to exercise its ability to carryback federal net operating losses to offset taxable income in prior periods. For the net operating losses it expects to carryback, the Company estimated the portion considered refundable and recorded receivables of approximately $22.8 million for both June 30, 2020 and September 30, 2019, as a component of other noncurrent assets on the Unaudited Condensed Consolidated Balance Sheets. Upon filing amended federal income tax returns to carryback its remaining federal net operating losses the Company will recapture tax credits totaling $24.1 million, the Company will reduce its taxable income in those periods and recapture federal investment tax credits of the same amount that were previously utilized to offset taxable income. The Company had state income tax net operating losses of approximately $489.7 million and $340.2 million for June 30, 2020 and September 30, 2019, respectively. These state net operating losses have varying carry-forward periods dictated by the state in which they were incurred. These state carry forward periods range from seven to 20 years and would begin to expire in fiscal 2021, with the majority expiring after 2035. The Company expects to utilize this entire carryforward, other than as described below. In February 2019, Clean Energy Ventures finalized the sale of its remaining wind assets. As a result of the sale, it is more likely than not that a portion of certain state net operating loss carryforwards will not be realizable prior to their expiration. The Company had a valuation allowance of $1.8 million and $4 million for June 30, 2020 and September 30, 2019, respectively, related to state net operating loss carryforwards in Montana, Iowa and Kansas. The remaining state income tax net operating losses are expected to be utilized prior to expiration. As a result of changes to filing requirements in the State of New Jersey that require tax returns filed for periods ending on or after July 31, 2019 be filed on a combined basis when part of an affiliated group, the Company recorded a benefit from income taxes of approximately $15.3 million during the nine months ended June 30, 2020, resulting from the re-measurement of deferred income tax attributes. The Company also evaluated its New Jersey state net operating loss carryforwards on a post-apportionment basis and determined it is more likely than not that a portion of these net operating loss carryforwards may not be realizable prior to their expiration. As a result, the Company recorded a valuation allowance associated with New Jersey state net operating loss carryforwards of approximately $13.6 million as of June 30, 2020. The Consolidated Appropriations Act extended the 30 percent ITC for solar property that is under construction on or before December 31, 2019. The credit will decline to 26 percent for property under construction during 2020 and to 22 percent for property under construction during 2021. For any property that is under construction before 2022, but not placed in service before 2024, the ITC will be reduced to 10 percent. Projects placed in service after December 31, 2019, may also qualify for a 30 percent federal ITC if five percent or more of the total costs of a solar property are incurred before the end of the applicable year and there are continuous efforts to advance towards completion of the project, based on the IRS guidance around ITC safe harbor determination. The Company has taken steps to preserve the current ITC rates for solar projects that are completed after the scheduled reduction in rates, in accordance with IRS guidance. As of June 30, 2020, the IRS has an open examination of the Company's federal income tax return for fiscal 2016. All periods subsequent to those ended September 30, 2014, are statutorily open for both state and federal examinations.
