Add Wyoming's 4% state sales tax onto a price, or reverse a tax-inclusive total back to the pre-tax price.
Wyoming's state base sales tax rate is pre-filled at 4% (as of September 17, 2026, per the Tax Foundation and U.S. Department of Labor). Most cities/counties add local sales tax on top, so your actual combined rate at checkout is often higher -- edit the rate below if you know your local combined rate, and always verify at your state's department of revenue for anything that matters.
Wyoming's state-level base sales tax rate is 4% (as of September 17, 2026, per the Tax Foundation and U.S. Department of Labor). Most cities and counties in Wyoming add their own local sales tax on top of this state rate, so the combined rate you actually pay at checkout is often higher -- this tool pre-fills the 4% state rate as a starting point, editable to your exact local combined rate.
Enter a pre-tax amount to add Wyoming's sales tax onto it, or switch to "Reverse" mode and enter a tax-inclusive total to back out the pre-tax price. The rate field is pre-filled but fully editable.
Among the 51 jurisdictions in this data set, Wyoming's 4% state rate ranks number 41 from the top. 5 jurisdictions charge no state sales tax, and among the ones that do, the simple unweighted average state rate is about 5.66% -- Wyoming sits 1.66 points below that figure.
Jurisdictions with the state rates closest to Wyoming's are Alabama (4%), Georgia (4%), Hawaii (4%). 4 other jurisdictions (Alabama, Georgia, Hawaii, New York) charge exactly the same state rate. Keep in mind that a state rate is only the first layer: the number that matters for a real purchase is the combined rate at the spot where you buy.
For context, Wyoming's general minimum wage is $7.25/hour -- see the Wyoming minimum wage calculator for how far that goes after this tax.
At Wyoming's 4% state rate, the state portion of the tax works out like this:
Now suppose the city or county where you shop adds a hypothetical 1.5% local tax, for a combined rate of 5.5%. The same $500.00 purchase would then cost $27.50 in tax instead of $20.00 -- a difference of $7.50 that the state-rate-only number would have missed. Use the rate field to enter your actual combined rate.
Reverse mode works backwards from a receipt. If a receipt in Wyoming shows $107.25 and only the 4% state tax was applied, the pre-tax price was 107.25 ÷ 1.0400 = $103.13, and the tax portion was $4.13. Dividing by one plus the rate (not subtracting the rate from the total) is the step people most often get wrong.
Taxable spending of $12,000.00 in a year carries $480.00 of Wyoming state sales tax. Taxable spending of $24,000.00 in a year carries $960.00 of Wyoming state sales tax. Taxable spending of $36,000.00 in a year carries $1,440.00 of Wyoming state sales tax. For comparison, the same three spending levels at the 5.66% average state rate among taxing jurisdictions would come to $679.30, $1,358.61, $2,037.91 respectively, so Wyoming residents pay $398.61 less per year on $24,000 of taxable spending than the average. Only a share of household spending is actually taxable (groceries, rent, and services are often exempt or taxed differently), so treat these as ceilings for planning rather than predictions of your real bill.
The 4% figure here is Wyoming's state-level rate only, pulled from a single published table -- it doesn't capture city/county add-on taxes where Wyoming permits them, special district taxes, or the product-specific rules that tax groceries, clothing, prepared food, or digital goods differently from ordinary merchandise. For a large purchase like a vehicle or appliances, look up the exact combined rate for the delivery address with Wyoming's own tax agency and enter that in the rate field instead. Businesses collecting and remitting sales tax have their own separate registration and filing requirements this calculator doesn't cover.
Not necessarily -- 4% is Wyoming's state-level rate only. Local city/county sales taxes commonly add more on top, so your real combined rate at checkout may be higher. Edit the rate field if you know your exact local combined rate.
Your state's Department of Revenue (or equivalent) publishes the current official rate and any local rate lookups -- always verify there for anything that matters, since rates can change.
At the 4% state rate, a $100.00 purchase carries $4.00 of state sales tax, for a total of $104.00 before any local tax.
Divide the total by 1.0400 (one plus the rate). For example, a $104.00 total at 4% was $100.00 before tax. Use the calculator's reverse mode to do this for any amount.
Wyoming sets its base sales tax at 4%. Compared with the 5.106% average across 51 jurisdictions, Wyoming is 1.106% below the average and ranks tied for 41st highest of 51 jurisdictions (with 4 others). 5 of them charge no state sales tax at all.
Wyoming's general minimum wage is $7.25 an hour -- see the Wyoming minimum wage calculator for how far that goes after this tax.
| Purchase price | State sales tax | Total at the state rate |
|---|---|---|
| $20 | $0.80 | $20.80 |
| $50 | $2.00 | $52.00 |
| $100 | $4.00 | $104.00 |
| $500 | $20.00 | $520.00 |
| $1,000 | $40.00 | $1,040.00 |
| $10,000 | $400.00 | $10,400.00 |
This is the state rate only. Many cities and counties add their own tax on top, and some items (groceries, clothing, medicine) are taxed differently, so the rate at your register can be higher than the figure above.
