Frequently asked questions
How much is sales tax on a car in Connecticut?
The Connecticut state vehicle sales/use tax rate is 6.35%. Multiply it by the taxable purchase price (usually the price minus any trade-in credit). Counties and cities may add a local sales tax on top, so confirm your combined rate with Connecticut Department of Motor Vehicles.
Do I pay sales tax when buying a used car from a private seller in Connecticut?
In most states, sales or use tax on a private-party vehicle purchase is collected when you title and register the car, not at the point of sale. The rate is generally the same as a dealer sale. Confirm the private-sale rules with Connecticut Department of Motor Vehicles.
Does Connecticut give a sales tax credit for a trade-in?
Most states tax only the difference between the vehicle price and your trade-in value, which lowers the tax you owe. A handful of states tax the full price with no trade-in credit. Verify Connecticut's treatment before you rely on the estimate above.
Are there local or county car sales taxes in Connecticut?
Often, yes. The rate shown here is the Connecticut state rate only; many counties, cities, and transit districts add a local sales tax on vehicle purchases, so your combined rate can be higher. Connecticut Department of Motor Vehicles publishes the official combined rates.
