Washington Income Tax: No State Tax

Washington is one of the few states with no state income tax. Residents of Washington only pay federal income tax on their earnings. Washington has no state income tax but levies a 7% tax on capital gains over $250,000 (upheld by the state supreme court in 2023).

While Washington does not tax income, residents still owe federal income tax using the standard IRS brackets. The 2026 federal rates range from 10% to 37% depending on your taxable income and filing status. This calculator shows your complete federal tax breakdown for Washington residents.

Tax Advantages of Living in Washington

Without state income tax, Washington residents keep more of their earnings compared to states like California (13.3% top rate) or New York (10.9%). For someone earning $100,000, the difference can be $5,000 to $10,000 per year in savings. This makes Washington especially attractive for high earners, retirees, and remote workers choosing where to live.

However, Washington may offset the lack of income tax through higher property taxes, sales taxes, or other fees. It is important to consider your total tax burden, not just income tax, when comparing states.

Filing Tips for Washington Residents

Since there is no state return to file, Washington residents only need to submit their federal tax return. Focus your tax planning on maximizing federal deductions: contribute to a 401(k) or IRA, use your HSA, and take the higher of the standard or itemized deduction. The 2026 standard deduction is $15,700 for single filers and $31,400 for married filing jointly.
