FAQ
What is the vehicle sales tax in Connecticut?
Connecticut charges a state-level rate of 6.35% on vehicle purchases. No local additions apply to vehicles. Trade-in value is deductible from the taxable basis.
Does Connecticut give a trade-in tax credit?
Yes. In Connecticut, the value of your trade-in is subtracted from the purchase price before sales tax is calculated. On a $20,000 car with a $5,000 trade-in, you only pay tax on $15,000.
What is the title transfer fee in Connecticut?
Connecticut charges approximately $25 for title transfer. Dealer documentation ("doc") fees typically range up to $449, though these are dealer-set and negotiable on most transactions.
How do I calculate out-the-door price in Connecticut?
Out-the-door = purchase price + (taxable amount × effective rate) + title fee + registration. Taxable amount equals purchase price minus trade-in (where allowed). Effective rate is state plus local. Use the calculator above for an exact figure on your specific purchase.
