What sales tax adds at the register
At the average combined rate of 5.39%:
| Price | Sales tax | Total |
|---|---|---|
| $25 | $1.35 | $26.35 |
| $100 | $5.39 | $105.39 |

Wyoming vs. the national average and its neighbors
The average combined state-and-local sales tax across the 50 states is about 6.66%. Wyoming's 5.39% is 1.27 points below that — on a $30,000 car, about $381 less than the national average buyer pays. Combined with no state income tax, that shapes how Wyoming funds itself — see the Wyoming paycheck calculator for the payroll side.
Border shopping is real: here's what the same purchases cost across state lines, at each state's average combined rate.
| State | Combined rate | Tax on $250 | Tax on $30,000 |
|---|---|---|---|
| Wyoming | 5.39% | $13.48 | $1,617 |
| Montana | 0% | $0.00 | $0 |
| Idaho | 6.03% | $15.08 | $1,809 |
| South Dakota | 6.11% | $15.28 | $1,833 |
| Nebraska | 6.98% | $17.45 | $2,094 |
| Utah | 7.42% | $18.55 | $2,226 |
| Colorado | 7.89% | $19.73 | $2,367 |
Vehicle purchases are usually taxed by the state where the car is registered, not where it's bought — so the car column shows the rate you'd owe as a resident, not a border-shopping opportunity.
Reading a Wyoming receipt
A Wyoming receipt typically shows tax as a single line at the combined rate, even though the money is split between the state and one or more local jurisdictions. To check a receipt: multiply the taxable subtotal by 0.0539 (the 5.39% average) — if the tax line is meaningfully higher, you're in a locality above the average, up to 7%; if lower, some items were exempt (groceries and prescriptions are exempt or reduced in most states). The reverse mode on the calculator above recovers the pre-tax price from any total.
