Massachusetts Title Transfer in a Private Sale: RTA, 10-Day Rule and Fees

To transfer a title after a Massachusetts private sale, the seller signs over the title with the mileage and sale price filled in, and you (the buyer) take it to a licensed Massachusetts insurance agent, who completes and stamps the Registration and Title Application (the RTA). Then you bring that packet to an RMV Service Center within 10 days of the purchase. Plan on a $75 title fee, a registration fee (the standard passenger plate is $60 for two years), 6.25 percent sales tax on the price or the NADA trade-in value, whichever is higher, and an inspection sticker within 7 days of registering.

I went through the RMV's private-purchase pages and the Department of Revenue's motor vehicle tax guide on October 16, 2026. Massachusetts trips up people moving in from other states because you do not start at the RMV. You start at an insurance agency, because the RTA has to carry the agent's stamp and signature before the RMV will touch it.

What the seller fills in on the title

The RMV page for vehicles purchased from an individual says federal and state law require the seller to state the mileage at transfer, and both buyer and seller hand print their names, sign and date. If the title has a space for the sale price, it must be filled in. If it does not, you need a bill of sale showing the price. Mass.gov's private party car sales guide lists what goes in the assignment on the back: date, price, both names, addresses and signatures, and the odometer reading.

Be picky here. The RMV says erasures, white-out and alterations will not be accepted, and the application has to be printed on plain white 8.5 by 11 paper. A title with a crossed-out date may bounce, and chasing a seller for a fresh signature after they have your cash is miserable.

The 10-day title rule and the 7-day plate transfer

There are two different clocks, and people mix them up. The first is the title deadline. Chapter 90D, Section 4 of the General Laws, says whoever acquires a vehicle must apply for a certificate of title within ten days, and the RMV's own page repeats it for motor vehicles and trailers over 3,000 pounds.

The second clock only matters if you already own a registered car. The RMV's 7-day transfer rule lets you move your existing plates to the car you just bought for up to seven calendar days after you sell or dispose of the old one. You must be 18 or older, the new car must be the same type with the same number of wheels, and you carry the transfer paperwork in it. With no registered vehicle now, there is no grace period, and the RMV issues no temporary plates. That is the honest negative here: a first-time owner needs a tow or a trailer.

What it costs: title, plates, sales tax and excise

The RMV lists the certificate of title at $75. Registration depends on plate type; the RMV Schedule of Fees shows a normal passenger plate at $60, renewed every two years. The bigger number is sales tax. For a private sale, the RMV calculates 6.25 percent of the purchase price or the NADA trade-in value, whichever is higher. So if you pay $8,000 for a sedan that NADA trades in at $8,000 or less, the tax is $500. Write $3,000 on the title for that car and the RMV still taxes book value, so the lowball-on-paper trick saves nothing.

Then there is the excise, which surprises a lot of new residents. Chapter 60A, Section 1, sets it at $25 per $1,000 of valuation, where the value is a shrinking share of the original list price, down to 10 percent from the fifth year on. A $30,000-list car in year five or later is about $75 a year. The RMV generates the bill, but you pay your city or town within 30 days of the issue date, and you owe it even if the bill never shows up in your mailbox.

Inspection, and the 7-day refund right

You need an inspection sticker within 7 days of the registration date. The fee schedule lists the annual inspection at $35. Do it fast for another reason too. The same guide says you may be entitled to a refund if the car fails inspection within seven days of the purchase date and the estimated repairs exceed 10 percent of what you paid. Separately, if a defect impairs safety or use and you can prove the seller knew and kept quiet, you can cancel the sale within 30 days, with the refund reduced by 15 cents a mile. Proving the seller knew is the hard part, so keep the ad and the texts.

One more thing. Under the used vehicle warranty law in Chapter 90, Section 7N1/4, anyone who sold more than three used cars in the past 12 months counts as a dealer. A "private seller" with four cars parked on the lawn is probably a curbstoner, and you lose the dealer warranty protections by buying from him as if he were your neighbor.

Check the history before you visit the agent

The RMV checks paperwork. It does not tell you the car sat in floodwater in another state two years ago. Match the VIN on the dash and door jamb to the title using our VIN verification for title transfer guide and search NMVTIS for brands. If anything comes back salvage or reconstructed, read our Massachusetts salvage and rebuilt title rules before you hand over money. Our CARFAX for private-party sales post covers what a report shows with no dealer involved, and used car sales tax compares Massachusetts with other states.

So, about that seller who texts you a PDF "CARFAX" and says it is all you need. Pull your own. CarVins is a licensed CARFAX and AutoCheck reseller, not affiliated with CARFAX, AutoCheck or Experian, and in mid October 2026 one report runs around $5.50 as a guest or $4.50 for members, with both reports on one VIN near $6.75, versus roughly $39.99 to $44.99 buying direct. Checkout shows the real total. CARFAX's own overview shows what a genuine report contains.
