    Connecticut charges 6.35% sales and use tax on a vehicle bought from a dealer, which is $1,587.50 on a $25,000 purchase with no trade-in.

    When you buy from a licensed dealer, the tax is based on the price after full trade-in credit. There is no separate city or county sales tax on a vehicle, so the state rate is the whole rate everywhere in Connecticut.

    A higher 7.75% rate applies to the portion of a vehicle's price above $50,000, which this calculator does not model; it applies the standard 6.35% rate to the whole price.

    Connecticut Car Title and Registration Fees

    Connecticut's DMV charges a $25 title fee and $120 for a standard 2-year passenger vehicle registration.

    How Connecticut Car Sales Tax Is Calculated

    1. Start with the purchase price from your dealer.
    2. Subtract your trade-in allowance.
    3. Multiply the result by the state rate of 6.35%.
    4. Add the $25 title fee and the $120 two-year registration fee to reach your out-the-door price.

    For a private-party sale, Connecticut bases the tax on the higher of the NADA average trade-in value or the price on the bill of sale, not simply what you paid.

    A higher 7.75% rate applies only to the slice of a vehicle's price above $50,000; this calculator applies the standard 6.35% rate across the whole price.

    If your vehicle's price is above $50,000, the portion above that threshold is taxed at 7.75% instead of 6.35%, which this calculator does not add in; use the DMV's sales tax calculator for an exact figure on a higher-priced vehicle.
