Income Tax in Washington
Washington (WA) has no state income tax for 2025. Residents pay only federal income tax and FICA taxes on their earned income.
Washington has no state income tax. Residents pay only federal income tax on wages and self-employment income; state revenue is collected through sales tax, property tax, severance taxes, or other non-income sources. The no-income-tax structure is a meaningful difference against high-tax peer states and is one of the largest single drivers of household after-tax income variation between states.
For households comparing Washington against other states, the full picture combines income tax (modeled by the calculator) with state and local sales tax, property tax, and any state-specific tax preferences. The compare tool on this site runs a side-by-side total-burden estimate; the per-state pages cover the income-tax piece in detail.
TaxCompare answers state and federal tax questions using the IRS Revenue Procedures and the Tax Foundation state-tax database — the authoritative current-year statutory sources. Every numeric answer on the site uses current-year brackets, deductions, and rates as published by those sources.
Two things to know. First, statutory rates and effective rates are different. A 6 percent state with deductions and credits can produce a lower effective tax than a 4 percent state with no deductions. The compare tool runs effective-rate calculations. Second, multi-state filers (work in one state, live in another) have residency rules the tool does not currently model; the output reflects single-state residence.
How Washington Income Tax Works
Washington is one of nine U.S. states with no broad-based personal income tax for tax year 2025. Wage and salary income earned by Washington residents is not subject to a state income tax line item; residents pay only federal income tax and FICA payroll taxes (Social Security and Medicare) on earned income. State revenue in Washington comes from a different mix — typically heavier reliance on sales tax, property tax, severance tax, or tourism-related excises depending on the state.
Compared to states with broad-based income taxes, Washington residents typically face higher sales and/or property tax to fund state government. Whether the no-income-tax structure leaves a household better off overall depends heavily on the household's spending and home-ownership profile, not just on its salary level.
Washington is one of nine U.S. states without a broad-based personal income tax. Residents keep more of each paycheck, but the state typically funds itself through higher sales tax, property tax, or severance tax. Whether the no-income-tax structure leaves a household better off depends on spending patterns and home ownership, not on salary level alone.
What This Page Cannot Tell You
The brackets and deductions above describe the statutory state-level rules. Your actual state tax liability depends on credits (earned-income credit, child credit, dependent credit), itemized deductions, retirement-income exclusions, local-government taxes (city or county income tax in some states), and federal taxable-income conformity rules. None of those interactions are computed here.
