Motor Vehicle Information

Motor vehicles are assessed at 70% of their "clean retail" value as published in the October Eastern Edition of the National Automobile Dealers Association (NADA) price guides. Vehicles which have active registrations on October 1st will appear on the Grand List (of the given year) and are taxed for the time period from October 1st to September 30th. These bills are due in July of the given tax year. Vehicles registered after October 1 of the given year but prior to August 1 of the following year appear on the Supplemental Grand List and are taxed from the month they are registered through to September 30. These bills are due in January of the following year.


If a vehicle has been disposed of during the described period, an owner may apply for an adjustment to their tax bill.
