What is the wisconsin sales tax calculator?
In short
Wisconsin charges a 5% state sales tax; with local taxes the statewide average reaches 5.7%. On $100 that is $5.00 in tax for an $105.00 total. Wisconsin pairs its 5% state rate with a 0.5% county tax in most counties; Milwaukee is the outlier at 2.9% local, so the total at the register varies meaningfully from county to county.
This calculator applies Wisconsin's 5% state base rate to any price and shows the tax and total instantly. Because Milwaukee and other localities can differ, it also lets you enter your exact combined rate. Wisconsin has one of the five lowest average combined sales-tax rates in the country at 5.70%.

Worked example
The scenario
A $500 purchase in Milwaukee, Wisconsin, where the combined rate is 7.9%.
The result
At the 5% state base rate the state tax is $25.00 ($525.00 total); at Milwaukee's 7.9% combined rate you'd pay more once local tax is added.
Common use cases
- Estimating the out-the-door cost of a Wisconsin purchase before you buy
- Comparing tax on a big-ticket item between Milwaukee (7.9%) and a lower-rate locality
- Seeing why your receipt differs from the 5% headline — the 2024 Milwaukee city and county increases were authorised by 2023 Wisconsin Act 12, partly to address local pension obligations.
- wisconsin exempts unprepared food but specifically taxes candy and soda — and draws the line by whether an item contains flour (flour-containing items are not 'candy')
Limitations & assumptions
- This tool uses the Wisconsin state base rate (5%); combined local rates vary — a 0.5% county tax in most counties; Milwaukee is the outlier at 2.9% local.
- Most groceries — meat, produce, dairy, bakery — are exempt, while prepared foods, candy, soft drinks and dietary supplements remain taxable.
- Rates change: Effective Jan 1, 2024, the City of Milwaukee added a new 2% city sales tax and Milwaukee County raised its rate to 0.9%, pushing the city's combined rate to 7.9%. Confirm with the Wisconsin Department of Revenue before filing.
- Use it to estimate costs — it isn't a substitute for professional tax advice.
