Motor Vehicle Excise Tax

FY2026 Bill Announcement

Three Important Reminders

  1. A bill for a vehicle that is no longer owned should not be ignored
  2. When a motor vehicle is registered, a motor vehicle excise bill is generated and the owner is responsible for its payment. If the owner moves within Massachusetts or out of state, if he or she sells or trades the motor vehicle, or if it is stolen, s/he needs to make every effort to obtain the bill, to pay it, and then to apply for an abatement if they are eligible. Filing an application down not stay the collection of your excise bill. To avoid interest, charges and collection action, including non-renewal of your registration, you must pay the bill in full within 30 days of its issue date. You will receive a refund if the abatement is granted.
  3. To avoid not receiving an excise bill on time, the owner should keep the Registry of Motor Vehicles aware of the current mailing address. There are several online transactions which can be performed at the Massachusetts Registry of Motor Vehicles website.

If You No Longer Own the Vehicle

If you no longer own the vehicle for which you have received an excise tax bill, you should contact the Assessor's office to apply for an abatement. We recommend that you pay the bill and then apply for an abatement to avoid late fees and penalties on any balances that are not abated. The Assessor's phone number is 617-993-2630.

Calculating Excise Bills

The amount of excise tax that is attributed to each vehicle is based upon a formula that begins with the list price of the vehicle when it was new. The excise tax is calculated by taking the list price value at a certain percentage, which depends on the age of the car, and multiplying that adjusted value by $25 per thousand.

Here's the table that the Registry of Motor Vehicles uses (Example of Tax Calculation for a List Price of $35,000):

Age of VehicleCalculation PercentageBill Valuation CalculationBill Amount (Valuation ÷ by 1000 × Rate)
In the year of manufacture90%$35,000 x 90% = $31,500$31.50 x 25 = $787.50
In the second year60%$35,000 x 60% = $21,000$21.00 x 25 = $525.00
In the third year40%$35,000 x 40% = $14,000$14.00 x 25 = $350.00
In the fourth year25%$35,000 x 25% = $8,750$8.75 x 25 = $218.75
In the fifth and succeeding years10%$35,000 x 10% = $3,500$3.50 x 25 = $87.50


Cars 5 Years or Older

Once your car is five years old or older, the excise tax amount does not change anymore, no matter how long the car is on the road and no matter what the actual value of the car. If you have an old car that was very expensive when it was new, and a newer car that is more economical, it is possible to pay a higher excise tax bill on the older car than you are paying on your new car.
