Wyoming sales tax rates
Wyoming's state sales and use tax rate is 4% (general rate) on 2026-10-22, in the Streamlined Sales Tax rate file WYR2026Q4AUG20 the state posted for 2026Q4.
The file also lists 25 local rates: 23 counties, 0 cities, towns and villages and 2 special districts. The rate on a sale adds the state rate and every local rate that applies at the location, so look up an address or ZIP code to see which apply.
A published rate is not the tax due on a sale: taxability, sourcing, nexus and exemptions all change what is owed.
Data as of Oct 21, 2026 (Olympus publication) · Markdown version
- These are published sales and use tax rates by jurisdiction. They are not the tax due on a transaction and not a taxability determination: whether an item is taxable, which location's rate applies (sourcing), whether the seller must collect (nexus) and any exemption all change what is owed. Rates come from the Streamlined Sales Tax files the states publish or, where a result's source says so, from the state revenue department's own files and pages; confirm with the state before relying on them.
- Wyoming's boundary file assigns jurisdictions almost entirely by ZIP+4 and 5-digit ZIP; few address ranges are current.
