Washington Capital Gains Tax Calculator

Washington State enacted a 7% excise tax on long-term capital gains under RCW 82.87, which took effect for gains realized on or after January 1, 2022 and was upheld by the Washington Supreme Court in 2023. The tax applies strictly to long-term capital gains from the sale of financial assets like stocks, bonds, crypto, and business equity exceeding a statutory standard deduction ($262,000 for 2026). Real estate, retirement accounts, and small family businesses are statutorily exempt. This calculator computes your exact Washington excise tax alongside federal capital gains brackets.
