Motor Vehicle Credits & Assessments

Reducing a Tax Bill for a Vehicle You No Longer Own:

Motor vehicles are assessed at 70 percent of their average retail value on each October 1st assessment date. Vehicles which have active registrations October 1st appear on the following January 31st grand list and bills are issued and due the following July.

Vehicles which are registered after October 1st, but prior to the following August 1st, appear on the supplemental grand list and are taxed from the month they are registered through the following September 30th. The bills for these 'supplemental motor vehicles' are issued and are due in January following the end of the assessment year.
