It is an annual tax for the privilege of registration. Every motor vehicle and trailer registered in Massachusetts is subject to excise tax unless expressly exempted. Registering a motor vehicle automatically triggers an excise tax. The city or town where the vehicle is principally garaged levies the excise annually. The Registry of Motor Vehicles prepares data for excise bills according to the information on the motor vehicle registration and sends it to the City or Town. Cities and Towns then prepare bills based on the excise data provided by the Registry of Motor Vehicles.

Additional information regarding excise taxes may be obtain on the web site of the Secretary of the Commonwealth of Massachusetts Citizens Information Service
