As a business, do I need to collect sales tax in Wyoming?

Businesses are required to collect sales tax in Wyoming if they have a sales tax nexus in the state. This includes having a physical presence or reaching a specific sales level, which establishes an economic nexus. This is why understanding Wyoming state sales tax obligations is crucial for compliance.


Do I have a physical nexus in Wyoming?

A physical nexus in the state of Wyoming is established if your business has a physical presence in the state, like an office, warehouse, or store. Even temporary physical presence, like participating in trade shows or craft fairs, can create a nexus.

In Wyoming, physical nexus is triggered by employees or contractors in any role — including back-office, administrative, and support functions, not just customer-facing roles.


How do I know if I have an economic nexus in Wyoming?

An economic nexus in Wyoming is determined by your sales volume. If your enterprise meets the threshold, you must register for a Wyoming sales tax permit, collect tax on sales shipped to Wyoming, and remit that tax to Wyoming Department of Revenue.

In Wyoming, economic nexus is established if your sales in the state exceed $100,000 OR the number of transactions exceeds 200, based on Current or Previous Calendar Year.

Marketplace sales (e.g., Amazon, eBay) are excluded when calculating whether you've exceeded the Wyoming economic nexus threshold.

Sales made for resale are included in the nexus threshold calculation for Wyoming.
