In Massachusetts, a bill of sale is required for every first-time boat registration and for most private vehicle sales, and it’s optional but strongly advisable for other personal property. Whether you need a separate document for a car depends on what’s printed on the title.
When a Vehicle Sale Requires One
Most Massachusetts vehicles carry a certificate of title with an assignment section on the back. When a private seller fills that section out completely — sale date, price, both parties’ names, addresses and signatures, and the odometer reading — the RMV treats the title itself as the record of sale, and a separate bill of sale isn’t strictly necessary.1Mass.gov. Private Party Car Sales If the title has no field for the sales price, the RMV won’t process the registration without a bill of sale showing what the buyer paid.2Mass.gov.

Older vehicles that are exempt from Massachusetts titling have no certificate at all. For those, the RMV needs both the previous owner’s registration and a bill of sale as proof of ownership before it will register the vehicle in your name.3Mass.gov. Transfer Your Registration to a Vehicle or Trailer Purchased From an Individual This is where most private-sale problems come up: the sale happens on a handshake, and the buyer later can’t register the car.
Even when the title covers it, a standalone bill of sale is worth keeping. Titles get lost, ink fades, and memories blur.
Boat Sales Always Require One
Massachusetts requires registration for any motorized boat and any boat used on public waterways, including motorized canoes, sailboats with motors, and jet skis.4Mass.gov. Boat Registration The Boat and Recreation Vehicle Registration and Titling Bureau requires a bill of sale for every first-time registration, with no exceptions.5Mass.gov. First-Time Boat Registration
The document must show the seller’s name, address, and signature. If you bought from a business, it has to be on company letterhead.5Mass.gov. First-Time Boat Registration Mass.gov offers a downloadable sample you can use as a template.4Mass.gov. Boat Registration
Furniture, Electronics, and Other Personal Property
No Massachusetts statute requires a bill of sale for everyday personal property. A written record is still worth the five minutes it takes. If a buyer later claims the item was stolen, or a seller tries to reclaim it, a signed document settles the question quickly. For cash transactions especially, the bill of sale may be the only proof that money ever changed hands.
What to Put on a Massachusetts Bill of Sale
For vehicles, the RMV expects the title assignment or a separate bill of sale to include the date of sale, purchase price, buyer’s and seller’s full names, addresses, and signatures, and the odometer reading. The vehicle description should cover make, model, year, color, and VIN.1Mass.gov. Private Party Car Sales
For boats, include the hull identification number (HIN), make, model, and length along with the same buyer and seller information.
For other personal property, there’s no official form. Cover the basics: both names and addresses, a clear description of the item, the price, the date, and both signatures. An “as-is” clause, a note of any known defects, and a statement that the item is free of liens can head off later disputes.
Signing, Deadlines, and Filing
Massachusetts does not require notarization. Both parties sign, and each keeps a copy.
For vehicles, you must apply for a certificate of title within 10 days of taking ownership.6General Court of Massachusetts. Massachusetts Code Chapter 90D Section 4 – Application for Certificate of Title Bring the completed Registration and Title Application, proof of ownership (the signed title, or for title-exempt vehicles the previous owner’s registration and your bill of sale), and payment to an RMV Service Center.2Mass.gov. Apply for a Registration and Title for a Vehicle Purchased From an Individual
For boats, submit the bill of sale and registration documents to the Boat and Recreation Vehicle Registration and Titling Bureau in person or by mail. Cash is not accepted.5Mass.gov. First-Time Boat Registration
For everything else, keep the signed original with your records. Nothing gets filed with the state.
A Note on Sales Tax
Massachusetts charges a 6.25% use tax on private vehicle sales, calculated on either the actual purchase price or the vehicle’s clean trade-in book value, whichever is higher.7Mass.gov. Motor Vehicle and Trailer Sales and Use Tax Writing a lower number on the bill of sale won’t reduce the tax owed if the book value is higher, and understating the price can create problems if the transaction is later scrutinized.2Mass.gov.

Gifts and Family Transfers
A vehicle received as a gift can be exempt from the 6.25% tax. The giver completes Form MVU-24, and the recipient pays a non-refundable $25 gift transfer fee plus standard title and registration fees.8Mass.gov. Family/Gift Transfers
Family transfers use a separate exemption on Form MVU-26, and it’s limited to transfers between a parent, sibling, spouse, or child. Grandparents, cousins, aunts, and uncles don’t qualify.8Mass.gov. Family/Gift Transfers Even when no money changes hands, a bill of sale documenting the transfer is still worth having.
