How This Calculator Works
Calculation methodology and assumptions
Washington's state sales tax rate is 6.5%. Local jurisdictions (cities and counties) may add up to 4%, bringing the maximum combined rate to 10.50%. Washington exempts most groceries (unprepared food for home consumption) from state sales tax. Prepared/restaurant food is still taxable. Washington taxes clothing at the same 6.5% general rate — there's no clothing-specific exemption. Select "Groceries" or "Clothing" as the item type above to apply these rules automatically. Sourced from Tax Foundation's state sales tax data, ITEP's State Tax Watch, and primary state Department of Revenue guidance, verified 2026-07.

Example Calculation
What would you pay in sales tax on a $500 purchase in Washington?
On a $500 purchase in Washington, the calculator multiplies by the combined state + average local sales tax rate. Washington's state rate is 6.5%, and local add-ons can push the combined rate to roughly 8.10%, sales tax would be about $41 for a total of $541.
Result: The difference between the highest and lowest taxable states matters most for big purchases. On a $30,000 car, sales tax alone can range from $0 in no-sales-tax states to well over $2,500 in the highest-rate states. Five states have no state sales tax: Oregon, Montana, Delaware, New Hampshire, and Alaska (though Alaska allows local taxes).
