Tax Credit Carryforwards
As of December 31, 2025, IDACORP had $70.9 million of Idaho investment tax credit carryforward which expires from 2034 to 2039.
Uncertain Tax Positions
IDACORP and Idaho Power believe that they have no material income tax uncertainties for 2025 and prior tax years. Both companies recognize interest accrued related to unrecognized tax benefits as interest expense and penalties as other expense.
IDACORP and Idaho Power are subject to examination by their major tax jurisdictions - United States federal and the State of Idaho. The open tax years for examination are 2023 through 2025 for federal and 2022 through 2025 for Idaho. In May 2009, IDACORP formally entered the U.S. Internal Revenue Service Compliance Assurance Process (CAP) program for its 2009 tax year and has remained in the CAP program for all subsequent years.
About Income Taxes Disclosures
The income tax disclosure reveals how much a company actually pays in taxes versus what the statutory rate would predict. Analysts focus on the effective tax rate (ETR) reconciliation, which breaks down every item driving the gap between the 21% federal rate and the company's reported ETR — including R&D credits, foreign rate differentials, and state taxes. Deferred tax assets (DTAs) and their valuation allowances signal management's confidence in future profitability: a rising allowance suggests the company doubts it can use accumulated tax benefits. Uncertain tax benefit (UTB) reserves quantify exposure to IRS challenges on aggressive positions.
Key signals to watch: sudden ETR drops without clear operational reasons, large increases in valuation allowances, growing UTB balances, and significant unremitted foreign earnings. Post-TCJA, pay attention to GILTI and BEAT provisions that affect multinational tax structures. Compare the cash taxes paid (from the cash flow statement) against the income tax provision to gauge earnings quality.
