I
NCOME TAXES We file a consolidated federal income tax return. Income tax expense allocated to our subsidiaries is based upon their respective taxable incomes and tax credits. State income tax returns are filed on a separate company basis in most states where we have operations and/or are required to file. Our federal and state corporate income tax returns for tax years after 2022 are subject to examination.
For federal income tax purposes, we have investment tax credits of $9.0 million, which begin to expire in 2044. For state income tax purposes, we have NOL carryforwards in various states of $192.1 million and $99.3 million as of December 31, 2025 and 2024, respectively, almost all of which will expire in 2040. We have not recorded a valuation allowance to reduce the future benefit of the investment tax credits or NOL carryforwards because we believe they will be fully utilized prior to expiration.
Tax Law Changes
On December 22, 2017, the TCJA was signed into law. Substantially all of the provisions of the TCJA were effective for taxable years beginning on or after January 1, 2018. The provisions that significantly impacted us include the reduction of the corporate federal income tax rate from 35 percent to 21 percent. Our federal income tax expense for periods beginning on January 1, 2018 are based on the new federal corporate income tax rate. The TCJA included changes to the Internal Revenue Code, which materially impacted our 2017 financial statements. ASC 740, Income Taxes, requires recognition of the effects of changes in tax laws in the period in which the law is enacted. ASC 740 requires deferred tax assets and liabilities to be measured at the enacted tax rate expected to apply when temporary differences are to be realized or settled. During 2018, we completed the assessment of the impact of accounting for certain effects of the TCJA. At the date of enactment in 2017, we re-measured deferred income taxes based upon the new corporate tax rate. See Note 17, Rates and Other Regulatory Activities, for further discussion of TCJA’s impact on our regulated businesses.
See Note 2, Summary of Significant Accounting Policies, for more information on tax law updates.
