Wisconsin Reverse Sales Tax Calculator
Wisconsin has a 5% state sales tax, making it one of the lower-rate states in the Midwest. Counties can add up to 0.5%, and Milwaukee County adds a 0.1% baseball stadium district tax, bringing Milwaukee's total to 5.6%. Most of Wisconsin is in the 5.0–5.6% range. It's a relatively low-tax state for sales — significantly below Illinois, Ohio, or Tennessee.
Milwaukee is at 5.6%, Madison and most other counties with a county tax are at 5.5%, and the handful of counties without a local tax are at exactly 5.0%. The statewide average is around 5.42%. Wisconsin is one of the more affordable states from a sales tax perspective, especially for larger purchases like furniture or electronics.

What's Taxable in Wisconsin
Wisconsin exempts most unprepared food (groceries) from the 5% state sales tax. Prescription drugs are exempt. Clothing is taxable (no exemption like Massachusetts or New Jersey). Restaurant meals and prepared food are taxable at the full combined rate. Wisconsin taxes services more broadly than some states — certain repair services, installation services, and telecommunications are taxable.
Worked Example
You bought tools in Milwaukee. Total on the receipt: $98.74 at Milwaukee's rate of 5.6%.
$98.74 ÷ 1.056 = $93.50 (pre-tax price)
$98.74 − $93.50 = $5.24 (tax amount)
That's $5.24 in sales tax on a $93.50 purchase before tax. The main calculator handles this automatically — enter the total and select your rate, and the pre-tax price and tax amount appear instantly.
Frequently Asked Questions
Milwaukee has a combined rate of 5.6% — 5% state, 0.5% Milwaukee County, and 0.1% baseball stadium district tax. This is slightly higher than other Wisconsin cities like Madison (5.5%) or Green Bay (5.5%) because of the stadium levy. For Milwaukee purchases, divide your total by 1.056 to find the pre-tax price.
Most unprepared food for home consumption is exempt from Wisconsin's 5% sales tax. Prepared food, restaurant meals, candy, and soft drinks are taxable at the full combined rate. Prescription drugs are fully exempt. The grocery exemption covers standard supermarket food items but doesn't extend to ready-to-eat food from deli counters or restaurants.

Wisconsin's state rate is 5% with modest local additions — most of Wisconsin is in the 5.0–5.6% range. This makes cross-border shopping into Wisconsin attractive for residents of the Chicago area, particularly for large purchases.
Divide your total by (1 + rate as a decimal). For Milwaukee at 5.6%: $98.74 ÷ 1.056 = $93.50 pre-tax. Tax = $98.74 − $93.50 = $5.24. For Madison or Green Bay at 5.5%, divide by 1.055.
