Wisconsin car sales tax calculator

How does Wisconsin tax a car, and which county and city taxes apply?

Wisconsin has no special car tax. A car pays the general sales and use tax: the state’s 5%, plus a county tax and, in the City of Milwaukee, a city tax. The county and city taxes follow where the car will be customarily kept, which is the buyer’s address, not the dealer’s. Most counties charge 0.5%. Milwaukee County charges 0.9%, and Waukesha and Winnebago counties charge none. The City of Milwaukee’s 2.0% is the only city sales tax in the state, so a car kept in the city pays 7.9% in all. The dealer collects all three at the sale. The tax is on the price with delivery and prep, the doc fee, add-ons and a service contract, less a trade-in. A premier resort area tax does not reach a car dealer’s sales.

Is there a limit on the Wisconsin dealer doc fee?

We found no dollar limit in Wisconsin law. Wisconsin calls the doc fee a service fee: a dealer may charge it for completing sales-related inspections or forms required by law, if it has made full disclosure. The rule says the fee is not required by law and must be reasonable, and WisDOT reserves the right to audit fees to see whether they are. Once disclosed, the fee may not be increased, but it may be reduced. An ad may leave it out of the price only if the ad clearly says the price does not include the optional service fee. The fee is taxed. Separately, a dealer that uses an outside vendor’s system may charge an optional electronic processing fee of up to $38, which is not taxed. Complaints go to WisDOT’s Dealer and Agent Section.

Do a trade-in and a rebate lower Wisconsin sales tax on a car?

A trade-in does, in full, with no cap, if the sale and the trade-in are one transaction. Selling your old car separately gives no credit, and neither do insurance proceeds for a totalled car. A trade-in worth more than the new car brings the taxable amount to zero, but the extra cannot offset a service contract sold with it. If you owe more than the trade-in is worth, the full allowance still comes off, and the debt the dealer takes on is not taxed. A maker’s rebate does not lower the tax: you still owe tax on the rebate’s amount. A dealer’s own discount, coupon or rebate does lower it.

What are Milwaukee's wheel taxes, and do other Wisconsin places charge one?

A wheel tax is a yearly flat registration fee a municipality or county can set for cars customarily kept there. WisDOT collects it at the first registration and at each renewal. The City of Milwaukee charges $41 and Milwaukee County $30, and a car kept in the city pays both. WisDOT’s list names many other places with a wheel tax, but they are not in our tables yet, so we have no figure for them. Outside the City of Milwaukee, the calculator shows a wheel tax line marked not included, with no amount. Check WisDOT’s list of current wheel tax jurisdictions for yours.

What do title and registration cost in Wisconsin?

The first title is $207, plus a supplemental title fee of $7.50. The title fee rose from $157 on October 1, 2025. Registration for an automobile is $85 a year. The amount is in the statute; the date it took effect is not confirmed. New plates cost $6 each, $12 for two, and are not charged when plates are transferred. Noting a lien on the title is $10. A hybrid adds $75 a year, and an electric car adds $175: a surcharge of $100 and an additional $75. Any wheel tax where the car is kept comes on top.

I bought a car out of state. What do I pay in Wisconsin?

A Wisconsin resident owes Wisconsin state, county and city use tax, for where the car is kept, when titling it, less credit for sales or use tax properly paid to another state. The credit covers state and local tax paid in another state or DC, up to the Wisconsin amount, but not tax paid to another country. A Wisconsin dealer that delivers the car outside the state as a courtesy delivery still collects the state and local use tax. A new resident owes no use tax on a car bought for personal use 90 days or more before moving in with a change of domicile. The title, at $214.50, and registration still apply. A nonresident who buys from a Wisconsin dealer and takes the car out of the state is exempt.
