Will my heirs pay any tax on what they inherit in Oklahoma?

Not a Oklahoma state death tax — Oklahoma has no estate or inheritance tax. Inherited assets are generally not treated as taxable income to the heir at the federal level either, though income later earned on those assets (interest, dividends, gains) is taxable. Very large estates may owe federal estate tax. (Source: Tax Foundation 2025.)

What about federal estate tax?

This page covers Oklahoma state-level death taxes only. Separately, the federal estate tax applies to estates above $13,990,000 per person for 2025 (with portability between spouses), at federal rates up to 40%. Most estates fall under the federal exemption. (Source: IRS; Tax Foundation 2025.)
