The 7.0% retail sales tax in Asotin County, Washington, is applied to most sales of personal property, retail sales, rental leases and on charges for selected services.

Manufacturers are exempt unless a product or service is used internally during the course of their operations. However, since July 1, 1995, manufacturing machinery and equipment is exempt. Also, the retail sales tax is not levied on the purchase of any raw materials or parts that become component parts or products manufactured for resale, nor is it levied on the purchase of any item for resale in the regular course of business.

All interstate and foreign sales from an in-state distribution facility are exempt from state and local retail sales taxes.
