No. The IRS does not treat inherited money, real estate or personal items as income, so a beneficiary in Washington does not report them on a federal return when received. Two exceptions: an inherited retirement account (a 401(k) or a traditional IRA) is taxed as ordinary income as it is withdrawn, and earnings after the date of death are taxable. Inherited property takes a stepped-up basis, its value on the date of death, for any later capital gain.
When someone dies, the cost basis of the property they leave is reset to its fair market value on the date of death26 USC § 1014Verified Sep 15, 2026View source under IRC § 1014. A later sale is taxed on the gain above that stepped-up basis, not above what the original owner paid, so the appreciation of the owner's lifetime is never taxed. The rule is federal and applies in Washington as in every state.
