Washington tax on stocks and ETFs

Washington uses a special rule: 7% tax on long-term capital gains above the annual threshold. stocks and ETFs gains still follow federal character first.

Federal rules for stocks and ETFs: Broker sales generally report on Form 1099-B and flow to Form 8949 and Schedule D. Wash-sale disallowance can apply if you repurchase a substantially identical security within 30 days. Holding period still matters for LTCG vs STCG except where a longer QSBS or real-estate test applies.

Open the parent Washington calculator for a generic sale, or the national Stocks lander for asset-only copy. Nearby states below keep the same stocks preset so you can compare residency. Estimates are not tax advice.

A stock or ETF loss can be disallowed if you buy the same or a substantially identical security inside the 30-day wash-sale window. This illustration does not turn that disallowance on.

This calculator models Washington long-term capital gains at 7% above $262,000. It does not apply a 9.9% tier on gain above $1 million, and it does not inflation-adjust the $262,000 figure for 2026.

Only long-term gain is run through that surtax. Short-term gain is not taxed by Washington in this model. A $50,000, $100,000, or $250,000 long-term gain sits under the $262,000 threshold, so the illustrated Washington line is $0. Gain above $262,000 is taxed at 7% on the excess only.
