Maine Trailer Bill of Sale — What You Need to Know

Sales Tax Details

Maine's 5.5% Sales and Use Tax applies to private trailer sales, paid at the Maine BMV agent office at the time of registration. Maine has no county-level sales tax. Unlike motor vehicles, trailers are not subject to the annual Maine excise tax.

Exemption: Farm trailers used exclusively for agricultural purposes may qualify for registration exemptions or reduced fees under Maine law — consult the Maine BMV or Maine Department of Agriculture for eligibility.

Inspection Requirements

Maine does not require a safety inspection for trailers at the point of sale or registration. There is no emissions testing for trailers in Maine.

Registration

Registration for this vehicle type is handled by Maine Bureau of Motor Vehicles — title and registration processed simultaneously at authorized BMV agent offices — not the same agency that handles cars in Maine. Plan for separate filings.

Maine Trailer Sale — Step-by-Step Checklist

1. Verify the trailer's GVWR from the manufacturer's plate on the trailer tongue or frame. Trailers 3,000 lbs+ GVWR require a title transfer; trailers under 3,000 lbs GVWR require registration only.
2. For titled trailers: seller endorses the Maine Certificate of Title to the buyer, completing all fields including any applicable odometer disclosure.
3. For registration-only trailers: seller provides the current Maine registration certificate and a signed bill of sale — no title to transfer.
4. Both parties sign a bill of sale with the VIN (or serial number), GVWR, year, make, model, sale price, date, and both parties' full names, addresses, and signatures.
5. Seller removes Maine trailer registration plate — Maine plates belong to the seller.
6. Buyer visits a Maine BMV agent office with Form MVD-355 (for titled trailers), signed title or registration certificate, and bill of sale.
7. Buyer pays the 5.5% Maine Sales and Use Tax on the sale price plus applicable title and registration fees at the BMV agent office.
8. Buyer receives a new Maine title (for GVWR 3,000 lbs+ trailers) and new registration in their name.

Common Pitfalls

• Misidentifying the GVWR threshold: Maine's trailer title threshold is 3,000 lbs GVWR — higher than some other states. A seller who provides only a registration certificate for a trailer that actually exceeds 3,000 lbs will cause the buyer's registration to fail at the BMV agent because a title transfer is required.
• Confusing the trailer excise tax question: Maine's annual excise tax applies to motor vehicles — cars, trucks, motorcycles — but not to trailers. Buyers expecting a town-office excise tax step (as with car purchases) do not need to make that stop for a trailer. Only the 5.5% sales tax at the BMV agent applies.
• Missing or damaged VIN/serial number plate: older trailers sometimes have illegible or missing identifier plates. Maine BMV requires a verifiable VIN or serial number for title and registration. If the plate is missing, contact Maine BMV before listing to determine the process for obtaining an assigned identifier.
• Leaving the plate on the trailer: Maine trailer plates belong to the seller. Allowing the buyer to tow the trailer using the seller's plate means the seller's registration record remains tied to a trailer they no longer own — remove the plate on the day of sale.

Pro Tip

Maine trailer transactions are among the simpler sales in the state precisely because trailers are exempt from the annual excise tax that complicates car and motorcycle purchases in Maine. The buyer's only financial obligation at the BMV agent is the 5.5% Sales and Use Tax plus standard registration and title fees — no prior stop at the town office required. Sellers should focus on two pre-sale tasks: confirming the GVWR from the manufacturer's plate (which determines whether a title is involved), and ensuring any existing title is clean and free of outstanding liens before listing.
