Do you need a bill of sale in Massachusetts?
For most private car sales in Massachusetts, a bill of sale is not legally required, but you should use one anyway. The Registry of Motor Vehicles transfers ownership through the certificate of title, not through the bill of sale. The bill of sale is your written proof of what was sold, to whom, for how much, and on what date.
Before completing the sale record, check our Massachusetts seller checklist for the order of the sale and handover steps.
There is one case where it stops being optional: vehicles from model year 1980 or older are exempt from titling in Massachusetts, and for those the RMV expects a bill of sale as the ownership document. If you are selling or buying a title-exempt classic, this piece of paper is the paper trail.
It also matters for taxes. The RMV calculates the 6.25 percent sales tax on the purchase price or the National Automobile Dealers Association value, whichever is higher. A clear bill of sale documents the real price you agreed on.

What a Massachusetts bill of sale must include
- Full legal names and addresses of the seller and the buyer
- Vehicle year, make, model, body style, and color
- The 17-character Vehicle Identification Number (VIN)
- Odometer reading at the time of sale
- Sale price in US dollars and the date of sale
- A statement that the vehicle is sold free of liens
- Signatures of both parties with dates
Notarization is not required in Massachusetts. Two signatures make the document valid. Both parties should keep a signed copy for at least a few years, since excise tax and insurance questions can surface long after the sale.
The bill of sale is step two. The title is step one.
A bill of sale alone does not transfer ownership. The seller must complete the assignment on the back of the certificate of title: buyer name and address, odometer reading, sale price, date, and both signatures. If you are unsure how that section works, our guide on how to transfer a car title in Massachusetts walks through it line by line.
The buyer then takes the assigned title, a completed Registration and Title Application stamped by their insurance agent, and payment for fees to the RMV. The full document stack is covered in our paperwork checklist for selling a car in Massachusetts.
Common mistakes that cause RMV problems
- Leaving the price blank. A blank price invites the RMV to tax the book value, and it invites disputes later. Write the real number.
- Rounding the odometer. The reading on the bill of sale should match the reading on the title assignment exactly.
- One copy for two people. Print two, sign both, each party keeps one.
- Using it instead of the title. For any vehicle from 1981 onward, the title does the legal work. The bill of sale supports it.
- Selling with a loan still on the car. The lien has to be released before the title can be assigned. Our guide on selling a car with a loan explains the payoff order.
Selling privately versus selling to a licensed buyer
A bill of sale protects you in a private sale, but it cannot make a stranger show up on time, pay what they promised, or handle the RMV steps correctly. If you would rather have the paperwork done for you, request a written offer from us. A local buying agent comes to you anywhere in Massachusetts, completes the title work and the bill of sale on the spot, and payment is made by business check or certified bank check at handover.

Can I write my own bill of sale in Massachusetts?
Yes. Massachusetts has no mandated form for private parties. Any document with the buyer, seller, vehicle, price, date, and signatures works. Our free template above covers all of it.
Does a Massachusetts bill of sale need to be notarized?
No. Signatures of the buyer and the seller are enough. Notarizing does no harm and can help if you expect any dispute, but it is not required.
Do I need a bill of sale to register a car in Massachusetts?
For a titled vehicle, the RMV registers the buyer using the assigned title and the RTA form. For a 1980-or-older vehicle without a title, the bill of sale acts as the ownership document and is required.
What if the car is a gift?
Write the word gift in the price field and use the matching Department of Revenue exemption form. We cover the process in our guide on gifting a car in Massachusetts.
Should I keep the bill of sale after the sale?
Yes. Keep your copy at least until the next excise tax cycle closes and the registration and insurance are fully sorted. Most people keep it for a few years.
