FedRateCalc is not a tax agency and this is not tax advice. The state tax agency’s own rate page and lookup tool are authoritative, and a seller’s receipt shows the tax actually charged.
Wyoming rate and local taxes

The statute section we read (W.S. 39-15-104) does not say whether local sales taxes apply, so check the state’s own lookup for the combined rate at an address. This site does not show an average local rate because no official source publishes one.
Official statute: W.S. 39-15-104.
Worked example
A $200.00 purchase at the 4% state rate: $200.00 × 4% = $8.00 of state tax, so the total is $200.00 + $8.00 = $208.00 before any local tax. To work backward from a total that includes tax, divide it by 1 plus the combined rate.
