Connecticut is one of the states that taxes vehicles as personal property every year, not just at the time of purchase, which catches a lot of new residents and first-time car owners off guard. This Connecticut vehicle property tax calculator estimates your annual bill based on your car’s assessed value and your town’s mill rate, since rates vary by municipality across the state. Entering your vehicle’s approximate value gives you a realistic estimate of what to expect before your town sends the actual bill.

Property tax is separate from the one-time sales tax and registration fees you pay when you first buy or register a vehicle. If you’re comparing overall costs of owning a car in Connecticut versus another state, it’s worth factoring this annual tax into your total cost of ownership estimate, since it’s an ongoing expense many other states don’t charge at all.
