A Minnesota trailer bill of sale is the written record of a private-party trailer sale that the buyer takes to a deputy registrar to transfer ownership, prove what was paid, and pay the 6.875% motor vehicle sales tax the state calculates from that price.1Minnesota Office of the Revisor of Statutes. Minnesota Code 297B.02 – Rate Whether the trailer also needs a formal title depends on its gross weight, but the bill of sale matters in every private transaction.
What the Document Has to Contain
Minnesota does not publish one mandatory statewide form. The document just needs enough detail for Driver and Vehicle Services (DVS) to process the transfer. Include:
- Full legal names and current addresses of the buyer and seller.
- Date of sale and the purchase price. The state uses this price to calculate the 6.875% sales tax, and understating it to reduce tax is illegal.
- Year, make, and model of the trailer.
- The Vehicle Identification Number (VIN) or serial number, which ties the paperwork to a specific unit in the state database. Manufacturers usually stamp the VIN into the frame near the tongue or on a riveted plate on the chassis.
- Signatures and the date from both parties.
Keep a copy for each side. Some county registrars publish their own fill-in forms, which is a good way to avoid missing a field.2Anoka County Minnesota. Trailer Bill of Sale Note significant damage or any equipment included in the sale so the document matches what actually changed hands. Notarization is not required.
Does the Trailer Need a Title or Just Registration?
Minnesota sorts trailers by gross vehicle weight (GVW), and the weight decides whether the state issues a certificate of title or only a registration.
Over 4,000 Pounds
Trailers with a GVW above 4,000 pounds get a certificate of title much like a car. In a private sale, the seller signs the existing title over to the buyer, and the buyer brings both the signed title and the bill of sale to a deputy registrar. The bill of sale backs up the title assignment and establishes the price for tax purposes.
4,000 Pounds or Less
The registrar does not issue a title for a trailer at 4,000 pounds GVW or less, unless a lienholder holds a security interest in it or a title was previously issued by any state.3Minnesota Office of the Revisor of Statutes. Minnesota Code 168A.03 – Exempt Vehicles For these lighter trailers, the bill of sale is the primary proof of ownership. Keep it permanently. Without a title on file with the state, it is what you will rely on for insurance claims or a future resale.
3,000 Pounds or Less: Permanent Registration
Utility trailers registered at 3,000 pounds GVW or less qualify for permanent registration, sometimes called a lifetime sticker. The one-time registration tax is $55 for a trailer being registered in Minnesota for the first time, and the registration stays valid for the life of the trailer as long as the registered weight does not change.4Minnesota Office of the Revisor of Statutes. Minnesota Code 168.013 – Rate of Tax No annual renewal, no stickers to track.
Deadline: 10 Days From the Sale
Buyers have 10 days from the date of sale to file the title transfer at a deputy registrar. Miss that window and any right to use the seller’s plates or take credit for taxes the seller already paid on the trailer expires.5Minnesota Office of the Revisor of Statutes. Minnesota Code 168.301 – Vehicle Transfer Deadline; Fees; Suspension Penalties escalate:
- After 10 days, a $2 late fee is added to the transfer cost.
- After 30 days, the commissioner can suspend the trailer’s registration. Reinstatement adds a $10 fee on top of what you already owe.
- If law enforcement stops you and the registration is suspended, you can avoid a violation by showing, within seven days of being cited, proof that you already filed the transfer and paid all taxes and fees.
The $2 fee is minor. A suspension is not. Get to the registrar inside the 10-day window and the process stays clean.
What You’ll Pay at the Counter

On a $2,000 utility trailer, the sales tax alone runs about $137.50, before the administrative fees.
Gifts Within the Family
If the trailer is a genuine gift rather than a sale, the transfer may be exempt from the 6.875% sales tax. Minnesota allows this exemption for gifts between spouses, between parents and children, and between grandparents and grandchildren.9Minnesota Department of Revenue. Nontaxable Transactions No money can change hands. The bill of sale should list the purchase price as $0 and identify the family relationship. Administrative fees still apply. Siblings, aunts, uncles, and cousins do not qualify.
Homemade Trailers Need a State VIN First
A trailer someone built themselves has no manufacturer VIN, and Minnesota will not register or transfer it without one. The owner must have the trailer inspected and assigned a state VIN before it can move through a normal sale. An authorized inspector checks lights, brakes, safety chains, coupler, tires, and fenders, and the assigned VIN has to be permanently displayed on the frame. If you are buying a homemade trailer, confirm the seller has already completed this. Without a state-assigned VIN, the trailer cannot legally be transferred into your name.
What the Seller Should Do After the Sale
Sellers have their own step that is easy to skip. Report the sale to DVS.10Minnesota Department of Public Safety. Vehicle Title Report Vehicle Sold, Donated or Removed From State This notice does not transfer ownership by itself, but it protects you: if the buyer never registers the trailer and later collects toll violations, parking tickets, or worse, those problems can find their way back to the registered owner. DVS will suspend the trailer’s registration if the ownership documents and fees are not submitted within 30 days of the sale.
