Motor Vehicle Computation

An excise at the rate of $25 per one thousand dollars of valuation (effective 1/1/81) is levied on each motor vehicle. Information on the value of a motor vehicle is accessed electronically through a data bank complete with valuation figures. Different sources provide the valuation figures depending upon whether the motor vehicle is an automobile, a truck, a motorcycle, or a trailer. For example, automobile valuations are derived from figures published in the National Automobile Dealers Association Official Used Car Guide (NADA), to which the Registry has electronic access. Most public libraries have copies of NADA and other motor vehicle official guides.

Figures are the manufacturers’ list prices for vehicles in their year of manufacture. Present market value, price paid, or condition are not considered for excise tax purposes. The excise tax law (M.G.L. c.60A, s.1) establishes its own formula for valuation for state tax purposes whereby only the manufacturer’s list price and the age of the motor vehicle are considered. The formula is as follows:

In the year preceding the model year
(brand new car released before model year)

50%

In the model year

90%

In the second year

60%

In the third year

40%

In the fourth year

25%

In the fifth and succeeding years

10%

Every motor vehicle owner must pay an excise tax based on valuation of at least ten percent of the manufacturer’s list price; thus, owners of vehicles older than five years should have a fixed excise tax bill for succeeding years of ownership.
