Labor in most cases isn’t taxable in Wisconsin.  For instance, let’s say you broke the screen to your cell phone and take 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 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.

Sales tax reporting

How is sales tax collected?

When a business makes a sale of a taxable product or service, the business charges the appropriate sales tax rate to the customer.  This tax is collected by the business who then sends it to the Wisconsin Department of Revenue.

How much sales tax is charged?

The sales tax rate that is charged varies depending on the address of the business if the purchase is made in the store.  When shipping in-state, the sales tax is based on the address of the purchaser.

In addition to the statewide tax, there are additional local sales taxes that may be added by some counties.  To find sales tax rates, see the sales tax rates by zip code from the Wisconsin Department of Revenue.

 

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 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 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.

Sales tax on purchases for resale

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

Wholesalers and distributors will require a sales tax number and have the reseller to fill out a Wisconsin Sales Tax Exemption Certificate to document the items being purchased are for resale.
