How To Register For A Wisconsin Seller’s Permit

Most businesses starting in Wisconsin that are selling a product or offering certain services will need to register for a seller’s permit.  This is commonly referred to as a sales tax permit, sales tax license, sales tax number, or sales tax registration.   

The seller’s permit is obtained through the Wisconsin Department of Revenue as a part of applying for the Wisconsin Business Tax Registration.  In addition to the seller’s permit, the Business Tax Registration allows a business to register for withholding tax and Use Tax Certificate.

Who needs a seller’s permit in Wisconsin?

A business must register for a seller’s permit in Wisconsin when making retail sales (this includes not only stores but selling locally at festivals, trade shows, and other events), leases, or rentals of tangible personal property or taxable services in Wisconsin unless all sales are exempt from sales or use tax.

What products and services are taxable in Wisconsin?

Physical products

There are a few exceptions, but almost all physical products are taxable when sold at retail in Wisconsin.  Common examples include:

  • General merchandise like furniture, appliances, and clothing
  • Titled or registered items like vehicles

Certain manufacturing and agriculture equipment, diaper services, some groceries, prescription medicine, and medical devices are tax-exempt.

Labor, in most cases, isn’t taxable in Wisconsin.  For instance, let’s say you broke the screen of your cell phone and took it to a cell phone repair shop to have it fixed.  Sales tax would be added to the selling price of the new screen and any additional parts to fix the phone.  The labor to replace the screen isn’t taxable.  However, a business that makes furniture will indirectly have a sales tax on labor.  In this instance, let’s say this business is building a dining room table for a customer.  Through labor, the pieces of wood are shaped, sanded, and painted to build this piece of furniture.  While the labor isn’t directly taxable, sales tax is charged to the final selling price of the table.

When are Wisconsin sales tax returns due?

The Department of Revenue will determine a filing frequency based on the expected volume of sales, which will be monthly, quarterly, or annually.  Generally, a business selling over $400 each month will file monthly. 

Filings are due on the last day of the month following the reporting period unless the last day of the month falls on a weekend or federal holiday, in which case it would move to the next business day.

Even if the business had no sales during the reporting period, a filing is still required indicating no sales occurred.

How do I get a wholesale license in Wisconsin?

A business can purchase items to resell without paying the retail sales tax.  The tax liability is passed from the wholesaler or distributor to the retailer, who will then charge state sales tax to the end-user of the item. 

Wholesalers and distributors will require a sales tax number, and the reseller will fill out a Wisconsin Sales Tax Exemption Certificate (also referred to as a resale certificate or seller’s permit) to document that the items being purchased are for resale. 


If you have questions about the seller’s permit, the Department of Revenue has Publication 201 – Wisconsin Sales and Use Tax Information. You can also contact them by calling 608-266-2776 or emailing DORBusinessTax@wisconsin.gov.
