Free Wisconsin Car Bill of Sale

Wisconsin routes car titles through the Department of Transportation — there is no standalone DMV and the Secretary of State has no vehicle role, a structure that regularly misdirects newcomers' paperwork. Form MV1 is the title/registration application, the bill of sale is optional (WisDOT includes a sample in Form MV2928), and the tax lands at 5% state plus 0.5% county in most places (Milwaukee County charges 0.9%, and the City of Milwaukee adds a 2% city tax). Emissions testing is a southeast-corner affair: seven counties including Milwaukee test most 1996-and-newer vehicles every other year (and may require a test within 45 days of a purchase), while the rest of the state never sees a testing station. Wisconsin is also a plates-to-owner state — the seller's plate comes off at the sale.

Wisconsin Requirements: If the vehicle will be operated, WisDOT says the buyer should title and register it within two business days after purchase (Wis. Stat. §341.04(1)(bm)2). 5% sales tax.

Wisconsin Car Bill of Sale — FAQs

Which Wisconsin counties need emissions testing?
Seven SE Wisconsin counties: Kenosha, Milwaukee, Ozaukee, Racine, Sheboygan, Washington, and Waukesha. Emissions is biennial, not annual. No statewide safety inspection.
Do I keep my plates in Wisconsin?
Yes — Wisconsin is a plates-to-owner state. Remove the plates when selling and transfer them to your next vehicle, or keep them — WisDOT says not to return the plates to the DMV.
How much is sales tax on a car in Milwaukee?
In Milwaukee County outside the city, the total is 5.9% (5% state + 0.9% county). Inside the City of Milwaukee, the 2% city tax brings it to 7.9%. Most other WI counties are 5.5% (5% + 0.5%). Madison (Dane County): 5.5%.
Do you need a bill of sale for a car in Wisconsin?
No. WisDOT says a bill of sale is not a required form. It offers form MV2928, Instructions for Selling a Vehicle, as an optional record you can copy for the buyer. You can also write your own. WisDOT suggests it list the make, year, model, VIN and odometer reading, plus the name, address and phone number of both the buyer and the seller.
Should I return my old plates to the Wisconsin DMV?
No. WisDOT says not to return plates to the DMV. Take them off any car or light truck of 8,000 pounds or less. You can move unexpired plates to a similar vehicle titled to you, your spouse or your domestic partner. If you won't reuse them, cut them up. There is no refund for unused registration time. If you forgot them on the car you sold, file a License Plates Cancellation Application.
Who signs when two people are on a Wisconsin title?
Look at the word between the names. If it says 'and', every owner listed must sign as seller. If it says 'or', any one of the owners may sign.
Can I sell a car in Wisconsin that is not titled in my name?
No. WisDOT says the car must be titled in your name before you sell it, even if you never drove it. If there is a loan, you must pay it off and get the title first. If you lost the title, apply for a replacement and sign that one over, even if the original turns up later. Destroy the original if you find it. Anyone who sells more than five vehicles in 12 months needs a dealer license.
Which local sales tax rate applies to a private car sale in Wisconsin?
The rate where the car will usually be kept, not where you buy it. A private seller does not collect the tax; the buyer pays it when titling. Since January 1, 2024, Milwaukee County's rate is 0.9% and the City of Milwaukee adds its own 2%, on top of the 5% state rate.
