Washington State Income Tax Overview
Washington has no state income tax on wages, salaries, or retirement income, which makes it attractive to workers and retirees — but it comes with an important nuance. Since 2022 Washington has levied a capital gains excise tax on large long-term investment gains: 7% on gains above an inflation-adjusted annual deduction (about $278,000 in 2025), rising to 9.9% on gains exceeding $1 million. The tax, upheld by the Washington Supreme Court in 2023, exempts most people — it does not touch wages, retirement accounts, or the sale of your home — but high earners with large investment gains are affected, and a separate high-earner income tax has been enacted to begin in 2028, so the picture continues to evolve. Washington funds its government largely through one of the higher combined sales tax rates in the country, around 9%, plus a business gross-receipts tax (the B&O tax) instead of a corporate income tax. Property taxes are moderate. Washington does levy a state estate tax, with a $3 million exemption and rates up to 35% — among the highest in the nation — so larger estates need planning. For a typical resident earning $100,000 in wages, the state income tax bill is still $0, versus roughly $6,000 or more in neighboring Oregon or California. Federal income tax applies to all taxable income using the same nationwide brackets.
