How much is sales tax in Wyoming?
Wyoming's state sales tax is a flat 4%, a low starting point. Combined rates range from 4% to 6%, averaging 5.28% across only 209 taxing jurisdictions. Burns reaches the 6% ceiling, but the overall range is remarkably tight compared to most states.

What's taxed and what's exempt in Wyoming
Groceries are exempt from Wyoming sales tax, easing the cost of living for residents. Clothing is taxable, so you'll collect tax on apparel purchases. The grocery exemption is one of Wyoming's shopper-friendly policies.
SaaS and digital software are not taxable in Wyoming, so software vendors don't collect sales tax on subscriptions. Prescription medicines are exempt as well. Restaurant and prepared food are taxable—diners pay the combined rate on takeout and dining-out purchases.
Do you have to collect Wyoming sales tax? (Economic nexus)
Like most states after the 2018 Wayfair decision, Wyoming requires out-of-state sellers to register and collect once their sales into the state cross an economic-nexus threshold. That line is commonly around $100,000 of sales into Wyoming per year, and some states also count a number of separate transactions — but the exact figure, and whether the transaction count still applies, change from time to time. Confirm Wyoming's current threshold before you rely on it.
If you sell into Wyoming from out of state, the practical question is whether you've crossed that line. Watching your sales into each state is how you know when you're on the hook — and it's the kind of thing that's easy to miss until a notice shows up.

How to calculate Wyoming sales tax
The math itself is simple: multiply the taxable price by the combined rate for the buyer's location. A $100 order at 5.282% means about $5.28 in tax. The hard part is getting the right rate for every address, keeping it current as rates change, and doing it fast enough to run inside a checkout.
That's what Sefro does. One API call returns the combined state, county, city, and special-district rate for any US address, sourced from state Departments of Revenue and refreshed weekly.
