How Washington nexus works

Washington sales tax nexus and economic nexus threshold: $100,000 in gross receipts sourced or attributed to Washington in the current or prior year (eff. 2020-01-01). The transaction-count threshold was eliminated when this unified threshold took effect. Crossing the threshold registers a remote seller for both retail sales tax AND Business & Occupation (B&O) tax — Washington classifies remote-seller revenue under the Retailing B&O classification, and a "No Local Activity" deduction is available when the seller has no in-state physical B&O nexus. Marketplace facilitator law (RCW 82.08.0531; marketplace facilitator defined at RCW 82.08.010(15)) applies the same $100,000 Washington-receipts threshold to marketplaces — Amazon, Etsy, eBay, and Walmart collect and remit Washington sales tax on third-party transactions they facilitate, and have provided monthly Washington-sales reports to their sellers since 2019-07-01. Direct-to-consumer Washington sales you make outside any marketplace continue to count toward your own $100,000 economic-nexus calculation.

Filing frequency

Filing frequency in Washington depends on your sales tax liability. Higher-volume sellers file monthly; lower-volume sellers typically file quarterly or annually. The state will assign a frequency when you register.

Marketplace facilitator law
