The state base rate and how local option taxes stack on top

Wyoming's statewide sales tax rate is 4%. Counties and municipalities can layer on local option sales taxes of up to 5% more, and across the state's roughly 105 local tax jurisdictions, the average local add-on runs about 1.34%, producing an average combined rate of about 5.36% -- genuinely low relative to most other states with a sales tax.

County rates range from 4% to 9%

Sublette County and Park County run the state's lowest combined rate at 4% (no local add-on), while Teton County runs the state's highest at 9%, reflecting the real revenue demands of a resort economy with a genuinely small, seasonal permanent tax base relative to its infrastructure and services needs. Most Wyoming counties fall somewhere in the 5%-6% range.

What's taxed, and what isn't

Wyoming's sales tax applies to most tangible retail goods and select services, with standard exemptions -- most notably groceries for home consumption, which are exempt from Wyoming sales tax statewide, a real, meaningful everyday-cost advantage relative to states that do tax groceries. Confirm current exemption specifics for any large purchase (vehicles, manufactured homes) directly with the Wyoming Department of Revenue, since those categories carry their own specific rules.
