How is My Bill Computed?
Excise tax on Motor Vehicles principally garaged in Westport is levied by the Town of Westport and revenues become part of the community treasury.
Excise Tax Bill Computation
Excise Tax is assessed at the rate of $25.00 per thousand dollars of taxable value. The value of a motor vehicle is determined by the Commissioner of Revenue, based on the manufacturer’s list price (MSRP). Condition and market value are not considered in determining value. Percentages are determined as follows:
- In the Year Prior to Model Year: 50%
- In the Year of Manufacture (Model Year): 90%
- Second Year: 60%
- Third Year: 40%
- Fourth Year: 25%
- Fifth Year, Each Year Thereafter: 10%
