Washington State Calculator

Washington is one of the few U.S. states without a personal income tax. However, that doesn’t mean residents are tax-free. From high sales taxes to potentially significant property and capital gains taxes, the Evergreen State has its own unique approach to taxation. To help Washingtonians (and those planning to move there) better understand their actual tax obligations, we’ve created a Washington State Tax Calculator — an intuitive tool designed to estimate your total tax burden based on your income type, location, and personal circumstances.

What Does the Washington State Tax Calculator Do?

This tool provides a comprehensive estimate of your tax liabilities in Washington State, including:

  • State Capital Gains Tax (for qualifying investment income)
  • Estimated Property Tax (based on homeownership and county)
  • Sales Tax (adjusted by income and dependents)
  • Total Tax Burden
  • Effective Tax Rate
  • Estimated Take-Home Income

It factors in various variables like your county, income type, filing status, and dependents to provide a highly personalized tax estimate. Whether you’re a business owner in King County or a retiree in Spokane, this calculator offers useful insight into your potential annual taxes.
