Should I register for sales tax in Wyoming?
Before you register for sales tax in Wyoming, check whether you actually have to. Registering when you don't owe just adds a recurring return — here's exactly when Wyoming requires it.
Confidence: moderate
Parts of this page (often the trailing-nexus timing) are still being verified, so our confidence here is moderate rather than high. Confirm anything you act on with Wyoming Department of Revenue – Excise Tax Division or a tax professional before you register or deregister.

You must register in Wyoming if you have physical presence there (inventory, staff, an office) or you cross $100,000 in sales (previous or current calendar year). Below that, with no physical presence, you generally don't have to.

When registration is required in Wyoming
Wyoming requires registration once you cross $100,000 in sales, measured over previous or current calendar year. Wyoming used to trigger nexus at 200 transactions but removed that count in July 2024 — only the sales figure matters now.
Physical presence registers you regardless of sales. Standard physical nexus triggers apply: physical location, employees, agents, representatives, delivery vehicles, and inventory stored in the state (including third-party fulfillment centers such as Amazon FBA warehouses) all create physical nexus immediately, regardless of sales volume.
The marketplace nuance most sellers miss
If you sell only through a marketplace like Amazon or Etsy, the marketplace facilitator generally collects and remits Wyoming tax for you, so you may not need your own permit. In Wyoming, facilitated sales do not count toward your own threshold.
How to register in Wyoming
Register through Wyoming Internet Filing System (WYIFS); the fee is $60. Wyoming is a full member of the Streamlined Sales Tax (SST) Agreement since January 1, 2008.
Don't over-register
Most over-registered sellers signed up defensively across many states after 2018. If you're under Wyoming's threshold with no physical presence, registering early just creates a recurring zero-dollar return. Register when you truly must — and track the states where you can stop.
Where TrailingZero fits
TrailingZero connects to your store read-only, maps where you actually have nexus state by state, and flags when you genuinely cross Wyoming's threshold — and where you've already dropped below and can deregister. 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.
