How much is the car sales tax rate in Wisconsin?

The statewide sales tax in Wisconsin is 5%, which applies to any car purchase, new or used. Depending on your county or local sales tax, you may have to pay more on top of the base tax.
You can find the highest combined sales tax rate in the cities of Baraboo, Wisconsin Dells, and Lake Delton in Sauk County at 6.75%.

Multiple Wisconsin counties only collect an extra 0.5% in sales tax, making the lowest combined sales tax 5.5%.

How are car trade-ins taxed in Wisconsin? 

Most dealerships will allow you to
trade in an old vehicle
for credits towards a new car with them. Since the trade-in value of your car is not subject to taxes in Wisconsin, this means you will only pay sales tax on your final ticket price. 
For example, you’re upgrading to a
Tesla Model S
worth $95,000 in
the city of Milwaukee
, and you’re trading in your old
Tesla Model 3
for a $9,500 credit. You’ll only have to pay Milwaukee County’s 5.5% combined state and local sales tax on $85,500 of the purchase. 
Dealer rebates and incentives are unfortunately not exempt from sales tax, meaning it will still be applied to the full price of the vehicle before dealer incentives.
