Worked Example
$100 spent in Wyoming at the 5.44% combined rate adds $5.44 tax, for a total of $105.44. Wyoming's 4% state rate is one of the lowest in the country; county-level add-ons (typically 1–2%) bring combined rates to 5–6%. Wyoming has no state income tax — revenue comes from severance taxes on coal, oil, gas, and trona (Wyoming produces over 90% of the world's trona).

Wyoming's low population and broad base (mineral severance) keep the headline sales-tax rate modest. Use tax applies to out-of-state purchases.
Key Insight
Wyoming's low population and broad base (mineral severance) keep the headline sales-tax rate modest. Use tax applies to out-of-state purchases. The 4% Wyoming state rate gets layered with local jurisdictions to reach the 5.44% Tax Foundation combined figure — useful as a ballpark for Wyoming shoppers and a sanity check for Wyoming-bound sellers, but a multi-jurisdiction online retailer with Wyoming nexus needs the destination-specific rate per ZIP (via Avalara, TaxJar, Stripe Tax). Wyoming exempts most groceries (unprepared food). Prescription drugs exempt. Clothing fully taxable.
Why the 'combined' rate matters
U.S. sales tax is layered: a state statutory rate plus local add-ons (county, city, special districts). For Wyoming, the Tax Foundation publishes a single 'combined' figure by population-weighting all local rates — 5.44% as of January 2026.
This number is useful as a ballpark for consumer-side checkout estimation and statewide comparison, but it is NOT the rate you'd see at a specific store. Two stores in the same state, five miles apart, can have different combined rates because of district-level add-ons.
Wayfair (2018) and the destination-based rate
Before 2018, online sellers only collected sales tax in states where they had physical presence. South Dakota v. Wayfair changed that: a seller exceeding economic-nexus thresholds (typically $100k in sales or 200 transactions per state per year) must collect destination-based sales tax on shipments to that state.
Practical consequence for Wyoming: if you buy online from an out-of-state seller above the nexus threshold, they should charge YOUR Wyoming combined local rate, not theirs. If you're a seller, sales-tax automation (Avalara, TaxJar, Stripe Tax) handles the per-customer destination lookup.

In which Wyoming situations should I NOT trust this number?
