What is the Washington income tax rate for 2026?
Washington does not levy a broad personal income tax on wages. In this site’s `us-tax-brackets.json` file, `stateRates.WA` is 0.00 — so the calculator shows federal income tax and FICA only for wage earners. Washington does impose a separate excise on certain long-term capital gains above a threshold (often discussed as a 7% rate on gains over $250,000 for individuals), which is not modeled in this wage-income tool.
