What Is the Sales Tax Rate in Wisconsin?
Wisconsin charges a 5% state sales tax on most purchases. On top of that, most counties add a 0.5% county sales tax, which brings the typical combined rate to somewhere around 5.5% to 5.6% across most of the state. A handful of areas have carried small additional stadium or special-district taxes historically, which can push a local total slightly higher.
USACalculator built this Wisconsin version because the rate you actually pay depends on the county you're shopping in, not just the state's flat 5% base. Pick your rate below and the calculator applies it to your purchase automatically.
Using the Calculator
Wisconsin is preselected in the dropdown with a representative combined rate. Enter the price of what you're buying, or swap in your own county's exact combined rate if you know it, and the total updates immediately. Planning a bigger purchase, like a vehicle? Wisconsin taxes those under the same general sales tax framework, so it's worth checking our Wisconsin Car Loan Calculator to see the full cost picture.
How the Calculation Works
The formula is simple: multiply your purchase price by the combined tax rate to get the tax owed, then add that to the original price for your total. Wisconsin applies the state's 5% base plus the county rate tied to where the sale happens, which is why two purchases in different counties can post different totals even at the same sticker price.
Wisconsin-Specific Sales Tax Information
State Sales Tax
The base rate is 5% statewide, set by the Wisconsin Department of Revenue and applied to most tangible goods and many services.
County Sales Tax
Most Wisconsin counties add a 0.5% county sales tax on top of the state rate. This isn't universal, so a small number of counties stick with the base 5% rate alone, and the exact figure depends on the county where the purchase legally takes place.
Combined Rate
Across most of Wisconsin, the combined state and county rate typically lands around 5.5% to 5.6%. A few areas historically carried extra stadium district taxes on top of that, though those specific add-ons have shifted over time, so it's worth confirming the current local rate for large purchases.
Tax Exemptions
Most unprepared grocery food and prescription drugs are exempt from Wisconsin sales tax. Prepared food, restaurant meals, and many over-the-counter items generally remain taxable. General clothing purchases are not exempt in Wisconsin the way groceries and prescriptions are.
Example Calculation
Say you're buying a $250 item in a county with the typical combined rate of 5.5%. The math looks like this:
| Item | Amount |
| Purchase Price | $250.00 |
| Sales Tax (5.5%) | $13.75 |
| Total Price | $263.75 |
Buy the same item in a county without the extra 0.5% add-on, and the total drops slightly, even though the state's 5% base never changes.

Common Mistakes to Avoid
- Assuming the whole state pays the same 5.5% rate. Some counties skip the extra 0.5% add-on.
- Forgetting that vehicle purchases generally follow the same state-plus-county combined rate as other goods.
- Treating grocery exemptions as covering restaurant meals or prepared hot food, which stay taxable.
- Assuming clothing is exempt the way groceries are. It generally isn't in Wisconsin.
