Washington's threshold, in its own words
WA DOR: more than $100,000 in combined gross receipts sourced or attributed to Washington in the current or prior calendar year; the 200-transaction threshold was eliminated in 2019 (DOR nexus page, updated April 2020). Marketplace facilitators must collect on facilitated sales (RCW 82.08.0531). Local rates vary; use the rate where the customer receives the goods or services. Some business services became subject to retail sales tax October 1, 2025 (ESSB 5814).
Washington has a marketplace facilitator law, so sales through a marketplace that collects for you are handled by the marketplace.
