Frequently asked questions

What is the auto sales tax rate in Connecticut?
Connecticut's statewide base sales tax rate is 6.35%. Counties, cities, and special districts can add local sales taxes on top of the state rate, so the combined rate at your address may be higher. Verify the exact rate with the Connecticut state tax authority or your local DMV.
Does Connecticut allow a trade-in tax credit?
Yes. Connecticut allows a trade-in tax credit — your trade-in value is deducted from the taxable amount before tax is computed. For example, on a $40,000 car with a $10,000 trade-in, sales tax is computed on $30,000.
How is out-the-door price calculated in Connecticut?
Out-the-door price = vehicle price + sales tax + documentation, title, registration, and dealer fees − rebates. Use the calculator above to estimate yours.
Is this an official Connecticut DMV tax estimate?
No. This is an educational estimate. Actual taxes and fees vary by county, city, dealer, vehicle type, and timing. Confirm exact amounts with your dealer and the Connecticut DMV before signing.
