Wisconsin's statewide sales tax is 5 percent
Wisconsin charges a 5 percent sales tax on most goods and services. This is the base rate that applies across the entire state. However, many counties and municipalities add their own local sales tax on top of the state rate, so what you actually pay at the register depends on where you are shopping.
The total sales tax you see on your receipt is the combination of the state rate plus any local additions. A purchase in Madison will have a different total tax than the same purchase in Milwaukee, even though the state portion is always 5 percent.
Key Takeaways
- Wisconsin's state sales tax rate is 5 percent on most purchases.
- Counties and cities can add local sales tax on top of the state rate, making your total tax anywhere from 5 to 5.6 percent depending on location.
- Groceries, prescription medications, and medical devices are exempt from sales tax in Wisconsin.
- You can find your exact local rate by entering your address on the Wisconsin Department of Revenue website or asking a retailer in your area.
How local taxes add to the state rate
Wisconsin allows counties to impose an additional sales tax of up to 0.5 percent, and some municipalities can add even more in specific circumstances. This means the total sales tax you pay ranges from 5 percent (state only) to as high as 5.6 percent in areas where both county and local taxes explore.
For example, if you live in a county that has added a 0.5 percent county tax, your total rate would be 5.5 percent. If your city or village has also added a local tax for a specific purpose—such as funding transit or a convention center—that gets added on top as well.
The easiest way to find your exact rate is to check the Wisconsin Department of Revenue's sales tax lookup tool on their website, or straightforward ask a cashier at any local store what the total rate is in your area.
What is and is not taxed in Wisconsin
Not everything you buy is subject to sales tax. Groceries (unprepared food you cook at home) are not taxed. Prescription medications are also exempt. Medical devices prescribed by a doctor are generally not taxed either.
Restaurant meals, prepared foods, and food you eat on premises are taxed. Clothing is taxed. Services like haircuts, repairs, and labor are generally taxed. Digital goods and software subscriptions are taxed. If you are unsure whether a specific item is taxed, the retailer or the Department of Revenue can tell you.
Sales tax on online and out-of-state purchases
If you order something online from a retailer that has a physical location in Wisconsin or meets certain sales thresholds, Wisconsin sales tax applies to that purchase. The retailer collects the tax based on the address where the item is being shipped.
If you order from a retailer with no Wisconsin presence and below the federal threshold for collecting sales tax, you may not see tax added at checkout. However, Wisconsin residents are technically required to pay use tax on such purchases when they file their state income tax return—though most people do not report these small amounts.
Finding your specific local sales tax rate
Your exact sales tax rate depends on your city or village, not just your county. The Wisconsin Department of Revenue maintains an online lookup tool where you can enter your address and see the precise rate that applies to your location.
You can also call your local city or village clerk's office, or straightforward ask a cashier at any store in your area. They will know the rate when ready. If you are shopping in a different part of the state, ask before you check out so you know what to expect.
Sales tax on vehicles and major purchases
Vehicle sales are subject to Wisconsin sales tax. When you buy a car, truck, or motorcycle from a dealer, the tax is calculated on the purchase price and collected at the time of sale. If you buy a vehicle from a private party, you still owe sales tax when you register it with the Wisconsin Department of Motor Vehicles.
The same applies to other major purchases like boats, recreational vehicles, and heavy equipment. The tax is based on the sale price and the location where the item will be registered or used in Wisconsin.
How sales tax is used in Wisconsin
The 5 percent state sales tax revenue goes into Wisconsin's general fund, which supports state services like education, transportation, and public safety. Local sales taxes collected by counties and municipalities fund specific projects or services in those areas, such as public transit, convention centers, or local infrastructure.
When you see a local sales tax on your receipt, that portion stays in your community rather than going to the state capital. Some communities use these funds for specific voter-approved projects, while others use them for general operations.
Frequently Asked Questions
What is the total sales tax rate where I live?
The state rate is always 5 percent, but your total depends on local additions. Use the Wisconsin Department of Revenue's online lookup tool with your address, or ask a local retailer. Rates range from 5 to 5.6 percent across the state.
Are groceries taxed in Wisconsin?
No. Unprepared groceries you buy to cook at home are not taxed. However, prepared foods, restaurant meals, and food you eat on premises are taxed. The distinction is whether you are buying ingredients or a ready-to-eat meal.
Do I pay sales tax on online purchases?
If the retailer has a Wisconsin location or meets federal sales thresholds, yes—tax is collected based on your shipping address. If the retailer has no Wisconsin presence and is below the threshold, tax may not be added, though you technically owe use tax when filing your state return.
Is sales tax added to the price shown on the shelf?

Yes. You owe sales tax on the purchase price when you register the vehicle with the Wisconsin Department of Motor Vehicles, even if you bought it from a private seller rather than a dealer.
