Wisconsin Sales Tax Rate Range 2025

Wisconsin has a state sales tax rate of 5%. Additionally, counties can impose up to a 0.9% tax.

For instance, Prairie Du Chien City has a sales tax rate of 5.5%. This rate includes the Wisconsin state sales tax of 5% and the 0.5% Crawford County sales tax.

How to Calculate Sales Tax in Wisconsin

To calculate your sales tax in Wisconsin, you’ll have to add these rates:

• State sales tax
• County sales tax
• City sales tax

For instance, let’s calculate the total sales tax in the City of Milwaukee, in Milwaukee County :

• Wisconsin state sales tax rate of 5%
• Milwaukee County sales tax of 0.9%
• Milwaukee City sales tax rate of 2%

This brings the total sales tax rate to 7.9%, the state's highest sales tax rate.

Collecting Wisconsin Sales Tax from Customers

Let’s explore how you can collect Wisconsin state sales tax.

Do I Have to Collect Wisconsin Sales Tax from Customers?

If you meet these two requirements, then you’re liable to collect tax on sales revenue in Wisconsin: 

• You have sales tax nexus in Wisconsin.
• You sell taxable products or services in Wisconsin.

What Creates a Sales Tax Nexus in Wisconsin?

You have sales tax nexus in Wisconsin if you meet one of the following conditions:

• Economic Nexus: Out-of-state businesses whose gross sales into Wisconsin exceed $100,000 in the previous or current calendar year. 
• Physical Location: Businesses with employees or other personnel, a physical location, inventory, and other in-state business activities. 
• Events:  An out-of-state seller making sales at a temporary event in Wisconsin is liable for sales and use tax on its taxable sales. If the seller has no further business activity in the state after the end of their tax year, they may inactivate their Wisconsin seller’s permit. If a seller does not make any sales at the event itself but promotes future sales, the seller is still liable for tax on Wisconsin sales through the end of the seller’s tax year. A seller with an active seller’s permit remains liable for Wisconsin sales tax.

Do I Have to Collect Sales Tax from Wisconsin Customers if I Sell on Amazon, Walmart, Ebay, or Etsy?

No.

Wisconsin has a marketplace facilitator law, which means that marketplaces like Etsy or Amazon are required to collect sales tax on behalf of third-party sellers on their platforms. 

If you have a sales tax nexus in Wisconsin, remember you still need to collect sales tax on your other non-marketplace Wisconsin sales.

FAQs on Paying and Filing Wisconsin Sales Tax

What Is Use Tax?

You’ll need to pay use tax on items purchased without sales tax. Additionally, if the items are used, stored, or consumed in a county or city that imposes local taxes, you’ll have to pay the combined sales tax as use tax.

For example, if the item is used in Milwaukee City, Milwaukee County, you’ll have to pay the combined sales tax rate of 7.9%.

I Didn’t Collect any Wisconsin Sales Tax During this Period. Do I still Need to File a Return?

Yes. 

You should still file a “zero” return with the state even if you didn’t collect any sales tax over the taxable period.  

What Is the Penalty for Filing and/or Paying Wisconsin Sales Tax Late?

If your return is not filed by the due date, you will be subject to interest on the total sales and use taxes due at the rate of 1.5% per month until the tax is paid. 

Returns filed after the due date are subject to a $20 late filing fee and a negligence penalty equal to 5% of the total sales and use taxes due for each month or a fraction of a month the return is late, with a maximum penalty of 25%.

If a return is not filed and the Wisconsin DOR (Department of Revenue) estimates that you have sales tax due, an estimated assessment may be issued, and the assessment will include a penalty of 25% of the estimated tax.

Additionally, there is interest of 18% per year on any unpaid taxes that are delinquent.

What Is a Retailer’s Discount?

A retailer can deduct a portion of the sales tax they report on a sales and use tax return to cover the costs of reporting and collecting the tax.
