What this means for remote sellers
Wyoming uses a revenue-only economic nexus threshold. You establish nexus once your gross sales into Wyoming reach $100,000 during current or previous calendar year. The number of separate transactions does not affect the threshold.
How Wyoming compares to other states
Wyoming's $100,000 revenue threshold is the most common in the country — 42 jurisdictions use it. It is one of 29 jurisdictions that look at revenue only — the number of transactions does not count. Wyoming has joined the recent trend of states dropping the separate transaction-count test. Its 4% base sales-tax rate sits below the roughly 5.7% average state rate.
How the Wyoming threshold is measured
Wyoming measures the threshold over Current or previous calendar year. Gross sales generally include taxable and (in many states) exempt sales; rules on marketplace-facilitated sales vary. Verify the specifics with the Wyoming department of revenue.
Do marketplaces collect Wyoming sales tax?
Wyoming requires marketplace facilitators — platforms such as Amazon, Etsy, eBay, and Walmart — to collect and remit Wyoming sales tax on sales made through them. If you sell only through those marketplaces, the platform generally collects the tax for you. Sales you make directly — through your own website or store — still count toward your Wyoming economic nexus threshold and remain your responsibility. Whether marketplace-facilitated sales also count toward your own threshold varies, so confirm with the Wyoming Department of Revenue.
What to do if you've crossed it
- Register with the Wyoming Department of Revenue for a sales-tax permit.
- Begin collecting tax on taxable sales to Wyoming customers.
- File and remit on the schedule the state assigns.
- Confirm treatment of marketplace sales and any local taxes with a professional.
