Vendor Sales Tax Info - Milwaukee, WI
Sales Tax Rate: 7.9%*
*Updated 4/30/25
We are required to send a list of all participating vendors to the state of Wisconsin, so they will be expecting you to register for a seller’s permit (if you do not already have one) and remit sales tax after the event.
All vendors must register for a seller’s permit here:
https://tap.revenue.wi.gov/btr/_/
Once you file your sales and use tax return, you can close your account by request here:
(608) 264-4582 or DORBusinessTax@wisconsin.gov
At check-in you will be required to fill out an S240 Form before you are allowed to load-in.
Please have your seller’s permit number with you.
Information for the vendors can be found on their website: https://www.revenue.wi.gov/Pages/HTML/tempsell.aspx#event1
