Wisconsin Trailer Bill of Sale Overview
In Wisconsin, a trailer bill of sale is an essential document for any private party trailer transaction. The Wisconsin Department of Transportation requires a bill of sale to process trailer ownership transfers. Wisconsin requires titles for trailers with a GVWR over 3,000 lbs. Lighter trailers may be exempt from titling but still require registration. Whether you are selling a utility trailer, enclosed cargo trailer, travel trailer, or any other type, a properly completed bill of sale protects both parties and is needed to complete the transfer at the WI DMV.
Wisconsin charges a 5% state sales tax on trailer purchases (plus county tax (0-0.5%)). Wisconsin does not impose a strict transfer deadline, but completing the transfer promptly is recommended. The bill of sale serves as the primary record of the sale price, which is used to calculate any applicable sales tax. Both parties should keep copies of the signed bill of sale for their records.

Enter Seller Information
Include the seller's full legal name as it appears on the trailer title, current Wisconsin mailing address, and phone number.
Enter Buyer Information
Include the buyer's full legal name, current Wisconsin address, and phone number. The buyer's county of residence may determine where the transfer is processed and what local tax rate applies.
Describe the Trailer
Enter the year, make, model, trailer type (utility, enclosed, travel, flatbed, etc.), and color. Record the full VIN or serial number from the trailer's identification plate. Include the GVWR, overall length, number of axles, and hitch type.
