Motor Vehicle Valuation

Motor vehicles are valued using the pricing guides from J.D. Power (formerly the National Automobile Dealers Association (NADA)), as recommended by the State of Connecticut Office of Policy and Management.

Motor Vehicle Assessment Credit Documentation

Motor Vehicle tax bills are issued July 1^st and encompass the period from the preceding October 1^st to the next September 30^th. Assessments for Connecticut registered motor vehicles may be prorated if the vehicle was (1) sold, (2) totally damaged, (3) stolen not recovered or (4) removed from this state and registered in another state by such person who concurrently ceases to be a resident of this state.

For grand list years prior to 2023, documentation supporting an assessment proration for a motor vehicle must be provided within twenty-seven months of the date of assessment. For example, documentation to support a proration for the October 1^st, 2022 Grand List must be provided by December 31^st, 2024.

For grand list years 2023 and later, documentation supporting an assessment proration for a motor vehicle must be provided within three years from tax due date. For example, documentation to support a proration for the October 1^st, 2023 Grand List must be provided by July 1^st, 2027.

If the vehicle was replaced and the plates were transferred to another vehicle, the credit is applied to the replacement vehicle. The bill for the original vehicle is to be paid in full.

The Department of Motor Vehicles does not inform the City when plates are returned or when vehicles are disposed of. It is the taxpayer’s responsibility to provide the required documentation within the statutory time limit.

Please note that motor vehicles which are no longer registered, are taxable and must be declared annually on a personal property declaration.

Change in Residence

Connecticut registered motor vehicles are generally assessed in the town in which the owner of the vehicle resides as of October 1^st. There is no proration when you move from one Connecticut town to another. If you moved to another Connecticut town prior to October 1^st and neglected to update your registration with the Department of Motor Vehicles, your assessment may be removed and forwarded to your town of residence. 

You must provide documentation from the list below to prove residency. These documents must:

• Show your name and your Connecticut residence address.
• Be dated before October 1^st of the Grand List year in question.
• Be computer generated (typed). 

Documents to show residence in another Connecticut town: 

• Bill from a bank or mortgage company, utility company, credit card company, doctor, or hospital.
• Bank statement showing the bank’s name and mailing address.
• Pre-printed pay stub showing your employer’s name and address.
• Valid homeowner’s or renter’s insurance policy.
• Residential mortgage, lease, or rental contract.

You must update your registration with the Department of Motor Vehicles. Failure to do so will require you to go through the same process in subsequent grand list years.

Vehicles Not Registered in Connecticut

Motor vehicles that are not registered with the Connecticut Department of Motor Vehicles that are primarily located in Connecticut are required to be declared as personal property annually by November 1^st.

To obtain a residential parking permit New Haven taxes must be paid. If your vehicle is registered out of state, please visit the Assessor’s Office with your Driver’s License and a copy of your registration. Your vehicle will be assessed in order to determine your tax liability.
