1. What is motor vehicle excise tax?: It is an annual tax for the privilege of registration. Anyone who registers a vehicle with the Registry of Motor Vehicles (RMV) will be billed based on the information supplied to the RMV on the registrant's application. Chapter 60A of the Mass. General laws imposes an excise on the privilege of registering a motor vehicle or a trailer in the Commonwealth of Massachusetts. Non-registered vehicles remain subject to taxation as personal property. The excise is levied by the city or town where the vehicle is principally garaged and the revenues becomes part of the local community treasury. The RMV prepares data for excise bills according to the information on the motor vehicle registration and sends it to the Town Assessors. Bills are then prepared based on the excise data sent by the RMV.

3. What is the rate?: The rate is $25 per thousand of the valuation. This is the standard rate for the entire Commonwealth.

Based on valuation rates set by the state, vehicles are valued as follows:

50% of manufacturer's list price in the year preceding the designated year of manufacture (brand new car released before model year)
90% of manufacturer's list price (1st year)
60% of manufacturer's list price (2nd year)
40% of manufacturer's list price (3rd year)
25% of manufacturer's list price (4th year)
10% of manufacturer's list price (5th year)

5. How often will I get an excise tax bill?: Excise taxes are assessed annually on a calendar year basis by the Assessors of the town in which the vehicle is garaged as of January 1. If the motor vehicle is registered after January 31st, it is taxed for the period extending from the 1st day of the month in which it is registered to the end of the calendar year. For example, if a vehicle is registered on April 30, it will be taxable as of April 1, for the nine months of the year (April through December) and the excise due therefore, will be 9/12 of the full excise. In no event shall the excise be assessed for less than $5 nor shall an abatement or refund reduce an excise to less than $5.

12. How does non-payment of motor vehicle excise affect license and registration?: If the service warrant demanding final payment is ignored, the Deputy Collector may then notify the RMV of such non-payment, including all interest and fees. The Registry may then mark the individual's registration preventing the renewal of the vehicle registration and the owner's driver's license until such time any outstanding accounts are paid.
