Wyoming economic nexus threshold
Wyoming's economic nexus rule decides when out-of-state sellers must collect sales tax. Here's the current threshold, how it's measured, and how the transaction-count rule has changed.

What is economic nexus in Wyoming?
Economic nexus means you can owe sales tax in Wyoming based purely on your sales volume there — no physical presence required. It traces to the 2018 South Dakota v. Wayfair decision. Wyoming's threshold took effect February 2019.
Today the threshold is $100,000 in sales, measured over previous or current calendar year.
The transaction-count history
Wyoming used to trigger nexus at 200 transactions but removed that count in July 2024 — only the sales figure matters now.
That matters because the 200-transaction prong used to catch very small sellers — 200 orders can be just a few thousand dollars of sales. If transactions were the only reason you registered in Wyoming, that trigger is gone.
What counts toward the threshold
gross sales of tangible personal property, taxable and exempt services, and admissions into the state; marketplace sales facilitated by a registered marketplace facilitator are excluded from the remote seller's own threshold calculation
Marketplace-facilitated sales do not count toward your own Wyoming threshold.

TrailingZero connects to your store read-only, maps where you actually have nexus state by state, and tracks your sales against Wyoming's threshold so you register only when you truly cross it — and deregister when you fall below. During any wind-down it can file the zero-dollar returns so nothing lapses — and you only pay for the states you genuinely keep. Run a free audit anytime; this page is free education either way.
