Washington Sales Tax Calculator

You can use our Washington Sales Tax Calculator to look up sales tax rates in Washington by address / zip code. The calculator will show you the total sales tax amount, as well as the county, city, and special district tax rates in the selected location.

Washington has a 6.5% statewide sales tax rate, but also has 180 local tax jurisdictions (including cities, towns, counties, and special districts) that collect an average local sales tax of 2.438% on top of the state tax. This means that, depending on your location within Washington, the total tax you pay can be significantly higher than the 6.5% state sales tax.

For example, here is how much you would pay inclusive of sales tax on a $200.00 purchase in the cities with the highest and lowest sales taxes in Washington:

You can use our Washington sales tax calculator to determine the applicable sales tax for any location in Washington by entering the zip code in which the purchase takes place. You may also be interested in printing a Washington sales tax table for easy calculation of sales taxes when you can't access this calculator.

Keep in mind that some purchases may be exempt from sales tax, and others others may be subject to special sales tax rates. Sales tax jurisdiction rules can sometimes be too complicated to describe rate areas by zip code, so this calculator is provided for reference purposes only.
