If you own a Motor Vehicle in Connecticut on October 1st of any year, you are liable for property taxes on your motor vehicle. The Assessor's Office values all vehicles at 70% of current market value using State recommended price guides and available market data.
Adjustments to Your Motor Vehicle Tax
A prorated credit may be processed by the Assessor's Office if the vehicle was stolen and not recovered, totally destroyed, sold or registered in another state after October 1st, when written documentation is provided.
If the vehicle is replaced by another using the same registration plates, a credit will be applied automatically to your Supplemental Tax bill for the replacement vehicle the following January.
