Income Tax Disclosure [Abstract] |
Income Taxes | 10. Income Taxes We use the estimated effective tax rate method to calculate income taxes in interim periods. Certain items, including those deemed to be unusual, infrequent or that cannot be reliably estimated, are excluded from the estimated annual tax rate. In these cases, the actual tax expense or benefit is reported in the same period as the related item. As of September 30, 2025, and December 31, 2024, our current federal income tax liability primarily relates to applying the accounting standard for uncertainty in income taxes and is included as a component of other liabilities on our condensed consolidated balance sheets. See Note 9 for detail on the components of our other liabilities. As a mortgage guaranty insurer, we are eligible for a tax deduction, subject to certain limitations, under Internal Revenue Code Section 832(e) for amounts required by state law or regulation to be set aside in statutory contingency reserves. The deduction is allowed only to the extent that, in conjunction with quarterly federal tax payment due dates, we purchase non-interest bearing U.S. Mortgage Guaranty Tax and Loss Bonds issued by the U.S. Department of the Treasury in an amount equal to the tax benefit derived from deducting any portion of our statutory contingency reserves. As of September 30, 2025, and December 31, 2024, we held $1.0 billion and $921 million, respectively, of these bonds, which are included as prepaid federal income taxes on our condensed consolidated balance sheets. The corresponding deduction of our statutory contingency reserves resulted in the recognition of a net deferred tax liability. On July 4, 2025, the One Big Beautiful Bill Act (the “Act”) was enacted, which introduced permanent changes to the U.S. tax code. Among other items, and most relevant to Radian, the Act reinstates and makes permanent 100% bonus depreciation and restores the immediate expensing for domestic research and experimentation costs. This new legislation will not have a material impact on our consolidated financial statements. For information on income taxes related to discontinued operations, see Notes 2 and 3. For additional information on our income taxes, including our accounting policies, see Notes 2 and 10 of Notes to Consolidated Financial Statements in our 2024 Form 10-K.
