Neither state has a transaction-count trigger — only the dollar threshold matters.

Texas — nexus note

Texas sales tax nexus and SaaS taxability: economic nexus applies to remote sellers with $500,000 or more in total Texas revenue during the preceding twelve calendar months. After crossing that safe harbor, Texas requires a permit and sales/use tax collection no later than the first day of the fourth month after the threshold-crossing month. Texas treats data processing as a taxable service and the Comptroller says data processing providers include software-as-a-service sellers and application service providers; 20% of a data-processing charge is exempt, so SaaS treated as data processing is generally taxed on 80% of the invoice amount. Marketplace-only sellers whose marketplace provider certifies Texas collection generally do not need a Texas tax permit, but sellers must keep marketplace-sales records for at least four years.

Washington — nexus note

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.
