Washington Tax Calculator
Washington has no state income tax — but the highest combined sales tax rate in the US at ~10.29%.
Washington levies no individual income tax but has the highest combined state-local sales tax rate in the nation: a 6.5% state rate plus local additions that bring the combined rate to approximately 10.29% in Seattle, Tacoma, and other metro areas, and as high as 10.6% in parts of the Puget Sound region. Property taxes are below the national mean at ~0.84%, but Washington's capital gains tax — enacted in 2021 and upheld by the state Supreme Court in 2023 — applies a 7% tax on long-term capital gains above $262,000 annually, functioning in practice like a partial income tax for high earners. The state has no estate or inheritance tax and offers a working families tax credit. Washington's tax structure relies heavily on consumption taxes and a major corporate sector — Amazon, Microsoft, Boeing, and Starbucks all generate substantial B&O tax revenue. The state's no-income-tax model has driven population growth but has raised regressive concerns.
