What You Need to Do to Register a Car in Massachusetts

To register a car in Massachusetts, you submit documents to the Registry of Motor Vehicles (RMV) — either in person at a branch office, by mail, or through their online portal for renewals. For a new registration, you'll need proof of ownership (the title or bill of sale), proof of Massachusetts residency, your driver's license or ID, and proof of insurance. The RMV processes most registrations within two to four weeks if submitted by mail, or when ready if you go in person and all documents are correct.

Massachusetts requires registration before you can legally drive on public roads. The state issues a registration certificate and a set of license plates (or a single plate if you're registering a motorcycle). Your registration is valid for two years from the issue date, after which you'll need to renew it.

Key Takeaways

  • You must bring or mail proof of ownership, proof of Massachusetts residency, a valid ID, and proof of insurance to the RMV to register a car.
  • New registrations take two to four weeks by mail or can be completed the same day in person at an RMV branch if your documents are in order.
  • Massachusetts registration is valid for two years; after that you'll renew by mail, online, or in person.
  • The RMV accepts registrations at 20 branch locations across the state, or you can mail documents to the main office in Boston.

Documents You Need for a New Registration

Start with proof of ownership. If you bought the car from a dealer, you'll have a title (the official ownership document). If you bought it from a private seller, you'll have a bill of sale signed by both parties. If the title is from another state, bring that — the RMV will issue a Massachusetts title as part of the registration process.

Proof of Massachusetts residency can be a utility bill, lease agreement, mortgage statement, or bank statement dated within the last 60 days showing your name and address. A driver's license with a Massachusetts address counts as both ID and residency proof.

You'll also need proof of insurance. Massachusetts requires all registered vehicles to carry liability insurance. Bring your insurance card or a declaration page from your insurer showing your policy number, coverage dates, and the vehicle identification number (VIN). Your insurance company can email or mail this to you if you don't have it yet.

Finally, bring a valid photo ID — your Massachusetts driver's license, out-of-state driver's license, passport, or state ID card. If someone else is registering the vehicle on your behalf, they'll need a signed power of attorney from you and their own ID.

Where and How to Submit Your Registration

The RMV operates 20 branch offices across Massachusetts. You can find the nearest one and check hours on the RMV website (mass.gov/rmv). Bring all your documents in person and the staff will process your registration on the spot — you'll leave with your registration certificate and plates the same day if everything is complete.

If you prefer to mail your documents, send them to the RMV's main office at 630 Washington Street, Boston, MA 02111. Include a completed process for Registration (Form REG-1), which you can read from the RMV website or pick up at any branch. Mail takes two to four weeks; the RMV will send your registration certificate and plates by mail once approved.

For renewals only, you can use the RMV's online portal at mass.gov/rmv if your registration is current and you haven't had any address changes. Online renewals are processed when ready and you can print a temporary registration while you wait for your new plates and certificate by mail.

Registration Fees and What They Cover

Massachusetts registration fees depend on the vehicle's weight and whether it's a passenger car, truck, or motorcycle. For a passenger car under 3,500 pounds, the fee is typically $50 for a two-year registration. Heavier vehicles, trucks, and commercial vehicles cost more. Motorcycles have a separate, lower fee structure.

Your registration fee covers the two-year registration period and includes one set of license plates (or one plate for motorcycles). If you need replacement plates because yours are damaged or lost, that's an additional fee of around $25 per plate.

Some vehicles may have access to for reduced fees. If you own a vehicle that's over 25 years old, you may register it as a historic vehicle at a lower rate. Disabled veterans and people with disabilities may also may have access to for fee reductions — ask at the RMV branch or check the website for current programs.

Special Cases: Leased Cars, Out-of-State Titles, and Salvage Vehicles

If you're leasing a car, the leasing company typically handles registration and you won't register it yourself. Check your lease agreement to confirm. If you do need to register a leased vehicle, bring the lease agreement along with the other standard documents.

If your car has an out-of-state title, you can still register it in Massachusetts. Bring the out-of-state title, and the RMV will issue a Massachusetts title as part of the registration process. If the title is from a state that doesn't issue titles for older vehicles, bring a bill of sale instead.

If you're buying a salvage vehicle (one that's been declared a total loss by an insurance company), it will have a salvage title. You can register a salvage vehicle in Massachusetts, but it must pass a safety inspection first. Schedule an inspection at an RMV-authorized inspection station, then bring the passing inspection report along with your other documents when you register.

What Happens After You Register

Once your registration is approved, you'll receive a registration certificate (also called a reg sticker or registration card) and license plates. Keep the registration certificate in your vehicle at all times — you're required to show it to police if stopped. The plates go on the front and back of your vehicle.

Your registration is valid for two years from the issue date. About 60 days before it expires, the RMV will mail you a renewal notice. You can renew by mail, online (if you're may be able to access), or in person at an RMV branch. If you miss the expiration date, you can still renew, but you may face a late fee.

If you sell the car, notify the RMV within 10 days by submitting a Notice of Sale (Form REG-14). This protects you from liability if the new owner gets a ticket or is involved in an accident. If you move to a new address, update your registration within 10 days as well.

Frequently Asked Questions

Can I register a car online in Massachusetts?

Online registration is available only for renewals of current registrations with no address changes. New registrations must be done in person at an RMV branch or by mail. If you're renewing online, you can print a temporary registration when ready while you wait for your new plates and certificate by mail.

How long does it take to get my registration if I go in person?

If you bring all required documents to an RMV branch and everything is correct, you'll receive your registration certificate and plates the same day. Processing takes about 30 minutes to an hour depending on how busy the branch is. Check the RMV website for current wait times at your nearest location.

What if I bought my car from a private seller and don't have a title yet?

If the seller has the title, they can sign it over to you and you bring it to the RMV. If the seller has lost the title, they can request a duplicate from the RMV in the state where the car is currently titled. Until you have the title or a bill of sale, you cannot register the vehicle in Massachusetts.

Do I need to register my car if I only drive it on private property?

No. Registration is required only for vehicles driven on public roads. If you keep your car on private property and never drive it on public streets or highways, you don't need to register it. However, most people register their vehicles because they drive on public roads at least occasionally.

What if my insurance lapses between when I register and when I renew?

Your registration remains valid, but driving without insurance is illegal in Massachusetts and you can be fined. If your insurance lapses, notify the RMV when ready — they may suspend your registration. Maintain continuous coverage to avoid penalties and keep your registration active.
