Washington has no state income tax. Your only income tax obligations are federal brackets. Calculate your exact marginal and effective federal tax rate below. Formula shown, sources cited — no account required.
Washington has no individual income tax, so residents face only federal brackets and payroll taxes. For a household earning the state median of $99,389, the federal effective rate typically runs around 15–17%, with no state return required. Washington funds state services through its high sales tax — averaging 9.51% combined — and business and occupation taxes on gross business revenue rather than profits. In 2022, the state added a 7% capital gains excise tax on long-term gains above $250,000 per year, which applies to stocks, bonds, and other capital assets but explicitly excludes real estate. That tax has been legally contested but remains in effect. For the vast majority of wage earners, the overall state-level tax burden remains low compared to states with full income taxes. High earners and investors with large capital gains should factor in the new excise tax when modeling Washington returns. Use a federal tax bracket calculator to identify your federal marginal rate and determine the most valuable pre-tax contributions for your situation.
Washington Tax Brackets Explained: No State Tax, Federal Only
Washington is one of the nine US states with no state income tax. Residents only pay federal income tax and FICA payroll taxes. This makes Washington attractive for high earners — a $200,000 income that would face 9–10% state tax in California or New York faces zero additional state burden here.
The median household in Washington earns $99,389/year. At that income (single filer), the federal effective rate is approximately 12–14%, bringing total income tax (federal + state) to roughly 12–14%.
How Marginal vs. Effective Rate Works
The marginal rate is the rate on your last dollar of income — it does not apply to all income. The effective rate is your total tax divided by total income. For example, someone earning $100,000 in Washington has a 22% federal marginal rate but an effective federal rate of roughly 15%, because the first $44,725 (2024) is taxed at 10% and 12%, not 22%.
