Special Considerations for Connecticut Vehicle Sales Tax
Connecticut has several unique rules that impact how much tax you owe:
- Trade-Ins: When you trade in a vehicle to a dealer, you only pay sales tax on the difference between the new vehicle’s price and your trade-in value, which can reduce your tax liability.
- Private Party Sales: Sales tax is calculated based on the purchase price or the vehicle’s fair market value (whichever is higher), even if the sale is private.
- Out-of-State Purchases: If you buy a vehicle out of state but register it in Connecticut, you must pay Connecticut sales tax on the purchase price or fair market value.
- Exemptions: Some transactions, such as gifts between family members or vehicle transfers due to inheritance, may be exempt from sales tax.
How Vehicle Sales Tax Is Collected in Connecticut
In Connecticut, sales tax is generally paid directly to the Department of Motor Vehicles (DMV) at the time of vehicle registration. This means that even if you purchase a vehicle from an out-of-state dealer, you’ll need to pay the applicable sales tax when you register the vehicle in Connecticut.
