Sales Tax By State
Wisconsin Sales Tax Guide for E-Commerce Retailers
Where Wisconsin sets its economic nexus threshold, when you have to register, and where the official answers live.
Am I required to collect sales tax in Wisconsin?
Businesses with an employee, a location or inventory in Wisconsin are required to register for a sales tax permit and collect sales tax from buyers in the state.
E-commerce businesses with economic nexus in Wisconsin are also required to register and collect. You have economic nexus in Wisconsin if you made more than $100,000 in gross sales into the state in the previous or current calendar year. Wisconsin removed its 200-transaction threshold effective February 20, 2021, so the dollar figure is the only trigger, and marketplace sales count toward it.
Once you cross the threshold, Wisconsin expects you to be registered before your next taxable sale. Our economic nexus chart keeps the state-by-state detail in one place.
How to register for a Wisconsin sales tax permit
You register with the Wisconsin Department of Revenue, or we register for you: permits filed in every state where you owe, with the state fees passed through at cost.
How to collect Wisconsin sales tax
Most Wisconsin counties add a 0.5% county tax. Milwaukee County’s is 0.9%, and the City of Milwaukee adds a 2% city tax.
Filing and due dates
Wisconsin assigns your filing frequency when you register, and each return has its own due date. Miss one and the penalty is automatic, whether or not you owed anything that period. If you would rather not track any of that, sales tax filings is the service where we file and pay every return on your schedule.
Not sure where you stand?
A Nexus Analysis tells you where you owe, Wisconsin included, before a state tells you first.
