Washington sales tax rates

Cities, counties and transit authorities add local rates to the 6.5% state rate. Washington taxes by destination, so a business that delivers charges the rate at the buyer's address.

Sales tax is charged at the rate for the place where the buyer takes delivery, so a business that ships within Washington charges the rate at the customer's address.

How to calculate it

Sales tax = price × combined rate. At 10%, a $1,000 sale carries $100.00 of tax and the customer pays $1,100.00.

To take the tax out of a tax-included total, divide by one plus the rate: $110.00 ÷ 1.1 = $100.00. Subtracting 10% of the total instead gives the wrong answer, because the rate applies to the pre-tax price.

What is not taxed in Washington

Groceries and prescription drugs are exempt. Washington has no income tax, which is part of why its sales tax is high.

Rates and exemptions change, so confirm the rate for a specific address with the Washington State Department of Revenue before you file. This calculator does the arithmetic; it is not tax advice.
