Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes Federal Income Tax Reform In December 2017, comprehensive changes in U.S. federal income taxes were enacted through legislation commonly known as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act made many significant modifications to the tax laws, including reducing the federal corporate income tax rate from 35% to 21% effective January 1, 2018. The Tax Act also eliminated federal bonus depreciation for utilities, limited interest deductibility for non-utility businesses and limited the deductibility of officer compensation. During 2020, the IRS issued final regulations related to certain officer compensation and, in January 2021, issued final regulations on interest deductibility that provide a 10% “de minimis” exception that allows entities with predominantly regulated activities to fully deduct interest expenses. In addition, in 2020, the IRS finalized regulations interpreting Tax Act amendments to depreciation provisions of the IRC that allowed the Company to claim a bonus depreciation deduction on certain construction projects placed in service subsequent to the third quarter of 2017. As a result of the change in the federal income tax rate, the Company re-measured and adjusted its deferred tax assets and liabilities as of December 31, 2017. The portion of that adjustment not related to PNM’s and TNMP’s regulated activities was recorded as a reduction in net deferred tax assets and an increase in income tax expense. The portion related to PNM’s and TNMP’s regulated activities was recorded as a reduction in net deferred tax liabilities and an increase in regulatory liabilities. Beginning February 2018, PNM’s NM 2016 Rate Case reflects the reduction in the federal corporate income tax rate, including amortization of excess deferred federal and state income taxes. In accordance with the order in that case, PNM is returning the protected portion of excess deferred federal income taxes to customers over the average remaining life of plant in service as of December 31, 2017 and the unprotected portion of excess deferred federal income taxes to customers over a period of approximately twenty-three years. Excess deferred state income taxes were returned to customers over a three-year period, which concluded in the first quarter of 2021. The approved settlement in the TNMP 2018 Rate Case includes a reduction in customer rates to reflect the impacts of the Tax Act beginning on January 1, 2019. PNMR, PNM, and TNMP amortized federal and state excess deferred income taxes of $24.5 million, $15.2 million, and $9.3 million in 2021. See additional discussion of PNM’s NM 2016 Rate Case and TNMP’s 2018 Rate Case in Note 17. As discussed in Note 17, the NM Supreme Court issued a decision in May 2019 on the appeal of the NM 2015 Rate Case resulting in pre-tax impairments of $150.6 million in the year ending December 31, 2019. The impairments were recognized as discrete items within regulatory disallowances and restructuring costs resulting in tax benefits of $45.7 million, which are reflected in income taxes on the Company’s Consolidated Statements of Earnings for the year ended December 31, 2019.

Included in the balance of unrecognized tax benefits at December 31, 2021 are $11.6 million, $8.6 million, and $0.1 million that, if recognized, would affect the effective tax rate for PNMR, PNM, and TNMP. The Company does not anticipate that any unrecognized tax expenses or unrecognized tax benefits will be reduced or settled in 2022. PNMR, PNM, and TNMP had no estimated interest income or expense related to income taxes for the years ended December 31, 2021, 2020, and 2019. There was no accumulated accrued interest receivable or payable related to income taxes as of December 31, 2021 and 2020. The Company files a federal consolidated and several consolidated and separate state income tax returns. The tax years prior to 2018 are closed to examination by either federal or state taxing authorities other than Arizona. The tax years prior to 2017 are closed to examination by Arizona taxing authorities. Other tax years are open to examination by federal and state taxing authorities and net operating loss carryforwards are open to examination for the years in which the carryforwards are utilized. At December 31, 2021, the Company has $196.2 million of federal net operating loss carryforwards that expire beginning in 2033 and $122.4 million of federal tax credit carryforwards that expire beginning in 2024. State net operating losses expire beginning in 2033 and vary from federal due to differences between state and federal tax law. The proposed Merger may impact the Company’s ability to utilize its federal net operating loss and tax credit carryforwards. In 2008, fifty percent bonus tax depreciation was enacted as a temporary two-year stimulus measure as part of the Economic Stimulus Act of 2008. Bonus tax depreciation in various forms has been extended since that time, including by the Protecting Americans from Tax Hikes Act of 2015. The 2015 act extended and phased-out bonus tax depreciation through 2019. As discussed above the Tax Act eliminated bonus depreciation for utilities effective September 28, 2017. However, in 2020 the IRS issued regulations interpreting Tax Act amendments to depreciation provisions of the IRC which allowed the Company to claim a bonus depreciation deduction on certain construction projects placed in service after the third quarter of 2017. As a result of the net operating loss carryforwards for income tax purposes created by bonus depreciation, certain tax carryforwards were not expected to be utilized before their expiration. In addition, as a result of Tax Act changes to the deductibility of officer compensation, certain deferred tax benefits related to compensation are not expected to be realized. The Company has impaired the deferred tax assets for tax carryforwards which are not expected to be utilized and for compensation that is not expected to be deductible. The Company earns investment tax credits for construction or purchase of eligible property. The Company uses the deferral method of accounting for these investment tax credits. The impairments after reflecting the expiration of carryforwards under applicable tax laws, net of federal tax benefit, for 2019 through 2021 are as follows:
