Motor Vehicles Assessments
Motor Vehicles are assessed according to State Statutes at 70% of the clean retail value through the use of the National Automobile Dealers Association (NADA) guides and other resources.
The uniform Assessment date is October 1st in Connecticut. Vehicles registered as of October 1st will be part of the October 1st Grand List. Vehicles registered after October 1st, but prior to August 1st, will be on the Supplemental list.
Disposal of a Vehicle
If you disposed of a vehicle and did not transfer the plates you may be eligible for a tax credit. The City is not informed when plates are canceled, so it is the taxpayer’s responsibility to provide the required documentation within the time limits. In accordance with CT State Statute application for tax credit needs to be made within 27 months of the assessment date.

If you transferred your plates from one vehicle to another you are not entitled to an adjustment. The bill you receive for the vehicle that was registered as of October 1st will be paid in full. You will receive a Supplemental bill for the new vehicle the plates were transferred to with a credit from the previous vehicle that was paid for in full.
