Washington Tax Calculator

The Washington (WA) Tax Calculator is updated for the 2026/27 tax year. Since Washington has no state income tax, this calculator focuses on estimating your federal income tax, FICA, and Medicare contributions. It helps residents and workers in Washington determine accurate take-home pay, accounting for all federal withholdings.

Although there is no personal income tax, Washington does apply other taxes such as sales tax, property tax, and the Business & Occupation (B&O) tax on certain income types. Use this tool to understand how federal and payroll deductions affect your total compensation.
