The formulas

  • Sales tax = sale x (4% + local rate)
  • Nexus when counted sales are more than $100,000 in the current or immediately preceding calendar year

How it works

Figures current as of November 2026.

The state rate is 4 percent: a 3 percent tax plus an additional 1 percent under W.S. 39-15-104(b). The tool multiplies the sale amount by the statewide base rate plus the local rate you enter (county sales tax for the delivery address) and shows the state and local parts separately. The local rate depends on where the goods are delivered.

A seller with no physical presence in Wyoming must register and collect once it has more than $100,000 of gross revenue from sales delivered into Wyoming in the current or immediately preceding calendar year. Enrolled Act 38 of 2024 (HB 197) removed the 200-transaction test effective July 1, 2024.

A seller with a physical presence in Wyoming, such as staff, an office or inventory, must collect regardless of the threshold. The tool does not decide whether a product is taxable or exempt; enter the taxable price.
