Combined rates are among the highest in the country because there is no state income tax. Washington is strictly destination-sourced, so the rate follows the delivery address.
How the Washington Sales Tax Calculator works
Washington has no state income tax, and sales tax carries the load instead — combined rates in the Seattle area exceed 10%. It is strictly destination-sourced, so the rate follows the delivery address down to the individual location, not the city or ZIP code.
Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price — check the platform's current fee schedule before you price a product against it. This is not tax or business advice.
Frequently asked questions
What is the Washington sales tax rate?
6.5% state plus local taxes, giving combined rates typically between 7.5% and 10.6%. Seattle and surrounding areas are at the top of that range.
How does destination sourcing work?
The rate is set by where the customer receives the goods. Washington provides address-level rate lookup because jurisdiction boundaries do not follow ZIP codes, and using ZIP-level rates produces errors.
Is shipping taxable?
Yes. Delivery charges are part of the selling price for sales tax purposes when the goods are taxable.
What is B&O tax?
Washington's Business and Occupation tax, a gross receipts tax charged in addition to sales tax. It applies to your revenue regardless of profit, and it catches out-of-state sellers who only budgeted for sales tax.
