Selling a trailer in Michigan — what to know

Michigan made trailer life simple in one way — trailer plates are permanent, bought once and staying with the trailer owner — but that simplicity puts extra weight on the sale paperwork. Many utility trailers in Michigan circulate without a title, so when one is sold, the signed bill of sale is frequently the only document that proves the transfer happened. The Secretary of State (SOS) office will want it when the buyer registers.

Write the trailer’s details carefully: the VIN or serial number from the tongue plate, the empty weight if known, and the real price. Michigan collects 6% use tax on private vehicle sales at transfer, calculated from the price on your paperwork.

Michigan Trailer bill of sale — FAQ

Do I need a bill of sale to sell a trailer in Michigan?
Yes, practically speaking — with permanent plates staying with the owner and many trailers untitled, the bill of sale is the document the SOS relies on at registration.
Does Michigan require notarization?
No. Both parties’ signatures are sufficient.
Does the plate come with the trailer?
No — Michigan trailer plates are permanent to the owner who bought them. As a buyer, budget for a new permanent plate at the SOS.
What tax will the buyer pay?
Michigan collects 6% use tax on the purchase price when the trailer is registered. State the real price on the bill of sale — understating it is illegal.
