How Washington administers sales tax

Rates are published by the Washington State Department of Revenue. Because local jurisdictions set their own increments, the correct rate depends on the delivery address rather than the seller's location for most remote sales. Confirm the current rate with the agency before filing — local increments frequently change on quarterly boundaries.
