What you pay to register a car in Massachusetts

Massachusetts charges a registration fee based on the vehicle's age and value, not a flat rate. The Registry of Motor Vehicles (RMV) uses a sliding scale: newer and more valuable cars cost more to register each year, while older vehicles cost less. The fee covers the cost of issuing your registration certificate and plates, and it renews annually on your birthday month or the month you first registered the vehicle.

The registration fee is separate from the excise tax, which is a local property tax on vehicle ownership that you pay to your city or town. Many people confuse the two because they often arrive in the same bill. The RMV collects the registration fee; your local assessor collects the excise tax.

You must register your vehicle within 10 days of purchase or moving to Massachusetts. If you buy a used car from a dealer, the dealer may handle the initial registration. If you buy from a private seller, you handle it yourself through the RMV online, by mail, or in person at an RMV branch.

Key Takeaways

  • Massachusetts registration fees range based on vehicle value and age, with newer cars paying more than older ones each year.
  • The registration fee renews annually in your birthday month or the month you first registered, and you can renew online, by mail, or in person.
  • Registration fees and excise taxes are two separate charges; the RMV collects registration fees while your city or town collects excise tax.
  • You must register within 10 days of purchase or moving to Massachusetts, or you may face late fees and loss of registration.

How the registration fee is calculated

The RMV uses a formula based on the manufacturer's suggested retail price (MSRP) and the vehicle's model year. The fee is not a percentage of the car's current value—it is based on what the car cost new. A 2024 sedan with an MSRP of $35,000 will have a higher registration fee than a 2015 sedan with an MSRP of $28,000, even if the older car is worth more today.

The exact fee schedule is published by the RMV and updated annually. For most vehicles, the fee ranges from around $50 for older, lower-value cars to several hundred dollars for new luxury vehicles. Hybrid and electric vehicles receive a discount on registration fees as an incentive. The RMV website includes a fee calculator where you can enter your vehicle's year, make, and model to see the estimated fee.

If you own multiple vehicles, each one registers separately and costs the full fee. There is no discount for registering more than one car. Commercial vehicles, motorcycles, and trailers have different fee structures.

When and how to renew your registration

Your registration renews on the same date each year—typically your birthday month or the month you first registered the vehicle. The RMV sends a renewal notice about 30 days before your registration expires. You can renew online through the RMV website if your vehicle has passed inspection, you have no outstanding violations, and your insurance is current. Online renewal takes a few minutes and costs the same as renewing by mail or in person.

If you renew by mail, send the renewal notice with your payment to the RMV. If you renew in person, visit any RMV branch with your renewal notice and payment. You do not need to bring the vehicle itself unless you are registering it for the first time or it has been out of registration for more than a year.

If your registration expires before you renew, you cannot legally drive the vehicle. Driving with an expired registration can result in a fine. If your registration lapses for more than a year, you may need to pass a new inspection and pay a reinstatement fee in addition to the registration fee.

Registration fees versus excise tax

The registration fee and excise tax are often confused because they appear on the same bill from your city or town. The registration fee goes to the state RMV and covers the cost of issuing your plates and registration certificate. The excise tax is a local property tax on vehicle ownership that goes to your city or town and is based on the vehicle's assessed value, not its original price.

Excise tax rates vary by municipality. Some cities and towns charge around $25 per $1,000 of assessed value, while others charge less. The excise tax is due annually, usually in the same month as your registration renewal. If you move to a new state, you stop paying Massachusetts excise tax but must register your vehicle in the new state.

Both fees must be paid to keep your registration current. If you owe excise tax, the town can place a lien on your vehicle or prevent you from renewing your registration until you pay.

What happens if you do not register on time

If you do not register your vehicle within 10 days of purchase or moving to Massachusetts, you face a late fee of $50 plus the regular registration fee. Driving an unregistered vehicle is illegal and can result in a traffic citation and fine. Police can stop you for expired or missing registration plates.

If your registration lapses and you do not renew within 30 days of expiration, the RMV may suspend your registration. A suspended registration means you cannot legally drive the vehicle and cannot renew until you pay the registration fee, any late fees, and any outstanding excise tax or violations. In some cases, you may also need to pass a new inspection.

If you are unable to renew because of financial hardship, contact your local RMV branch to discuss options. Some branches can work with you on payment plans or may direct you to local resources, though this varies by location.

Special cases: Temporary plates, transfers, and out-of-state vehicles

If you buy a new car from a dealer, the dealer issues temporary plates that are valid for about 10 days while you complete registration. Temporary plates allow you to drive legally during this period. You must complete permanent registration before the temporary plates expire.

If you transfer ownership of a vehicle to another person, the new owner must register it in their name within 10 days. The previous owner is no longer responsible for registration or excise tax once the transfer is complete. The new owner pays the full registration fee, not a prorated amount.

If you move to Massachusetts from another state, you have 10 days to register your vehicle with the Massachusetts RMV. You will need your out-of-state title, proof of insurance, and a passing inspection. Your out-of-state registration is no longer valid once you establish residency in Massachusetts.

Where to handle registration and what documents you need

You can register or renew your vehicle online through mass.gov/rmv, by mail, or at any RMV branch. Online renewal is the fastest option if you are renewing an existing registration. For new registrations, you may need to visit a branch or mail in documents depending on your situation.

For a new registration, bring or mail the vehicle's title, proof of insurance, a passing inspection certificate, and proof of residency. For renewal, you typically only need the renewal notice and payment. If your vehicle has been out of registration for more than a year, you may need to bring the vehicle for a new inspection.

RMV branches are located throughout Massachusetts. Wait times vary by location and time of day. You can check wait times on the RMV website before you visit. Some branches accept walk-ins; others require an appointment. Calling ahead or checking the website for your local branch is recommended.

Frequently Asked Questions

Can I register a vehicle online if I just bought it?

Not for a first-time registration. You can only register a new-to-you vehicle online if you are transferring an existing Massachusetts registration from another vehicle. For a first-time registration, you must visit an RMV branch or mail in your documents, including the title and inspection certificate.

What if I sell my car before my registration expires?

Once you sell the vehicle, you are no longer responsible for the registration or excise tax. The new owner must register it in their name within 10 days. You do not receive a refund for the unused portion of your registration fee. Report the sale to the RMV to protect yourself from liability if the new owner gets a ticket or is in an accident.

Do I have to pay registration fees if my car is parked and not driven?

Yes. Registration fees are required annually regardless of whether you drive the vehicle. If you own the car and it is registered in Massachusetts, you must renew the registration each year. If you do not plan to drive the vehicle, you can let the registration lapse, but you cannot legally drive it until you renew.

Are there any discounts on registration fees?

Hybrid and electric vehicles receive a discount on registration fees. Some disabled veterans may be exempt from registration fees. Check the RMV website or contact your local RMV branch to see if you may have access to for any exemptions or discounts based on your vehicle type or status.

What if I move out of Massachusetts?

You must register your vehicle in your new state within the timeframe required by that state, typically 10 to 30 days. Once you establish residency elsewhere, you stop paying Massachusetts excise tax and registration fees. Notify the Massachusetts RMV of your move to avoid future bills.
