Field guide

Washington’s sales tax, explained.

Washington has no state income tax, which shifts more of the state and local revenue burden onto sales tax (and the state's separate business & occupation tax). The state base sales tax rate is 6.5%, with cities and counties adding local rates on top.

Among the highest average combined rates in the country

Local additions in Washington can add roughly 2–3% on top of the 6.5% state rate, and the statewide average combined state + local rate lands around 9% — consistently ranked among the highest average combined sales tax rates of any U.S. state, a direct consequence of leaning on sales tax in place of an income tax.

Worked example

Say you make a $175 purchase at Washington’s 6.5% state base rate. The tax comes to $11.38, for a total of $186.38$175.00 pre-tax plus $11.38 in tax. Use the calculator above to re-run this at your actual combined (state + local) rate if it differs.

Disclaimer

The rate above is Washington’s 2026 state base rate and updates slowly; combined state + local rates change more often and vary by county or city. For tax filings or large purchases, confirm the exact combined rate with Washington’s Department of Revenue or an up-to-date ZIP-code lookup.
