The formulas

  • Sales tax = sale x (5% + local rate)
  • Nexus when counted sales are more than $100,000 in the previous or current calendar year
  • Counted sales = direct sales + marketplace sales

How it works

Figures current as of November 2026.

The state rate is 5 percent. The tool multiplies the sale amount by the statewide base rate plus the local rate you enter (county sales tax, plus the City of Milwaukee tax, for the delivery address) and shows the state and local parts separately. The local rate depends on where the goods are delivered.

A seller with no physical presence in Wisconsin must register and collect once it has more than $100,000 of gross sales into Wisconsin, including resale, taxable and exempt sales in the previous or current calendar year. The 200-transaction test was removed effective February 20, 2021. Sales you make through a marketplace facilitator count toward your own Wisconsin threshold, together with your direct sales.

A seller with a physical presence in Wisconsin, such as staff, an office or inventory, must collect regardless of the threshold. The tool does not decide whether a product is taxable or exempt; enter the taxable price.
