Supplemental Motor Vehicles
- If a marker plate was transferred to a new vehicle from an old vehicle, credit will be given on the new vehicle and further adjusted by the number of months of ownership.

How we Value our Vehicles
The motor vehicle pricing schedule is established by the State of Connecticut – Secretary of the Office of Policy and Management. The following guides are used Connecticut State Statutes Section 12-71D (use the average retail value):
- N.A.D.A. Motorcycle / Snowmobile / ATV / Personal Watercraft Appraisal Guide
- N.A.D.A. Official Older Used Car Guide
- N.A.D.A. Official Used Car Guide (New England Edition)
- N.A.D.A. Recreational Vehicle Appraisal Guide
Disposed of a Motor Vehicle?
A motor vehicle that had been sold, junked, totaled or registered out of state after October 2, 2022. The bills for July 2023 are for vehicles registered from October 1, 2022 through September 30, 2023. If you got rid of a vehicle and canceled the license plates any time during that assessment year, in order to have your bill pro-rated we require copies of the canceled plate receipt and some form of documentation as to what happened to the vehicle such as a bill of sale. See the list of acceptable forms of proof below. If the marker plates are not canceled or not used on another vehicle, the DMV will continue to list that vehicle as having a valid plate and continue to include it on the tax rolls.
Please note that the DMV DOES NOT notify this office when a plate is canceled.
