Connecticut’s luxury car tax applies a 7.75% sales tax rate to any passenger vehicle with a sales price above $50,000, replacing the standard 6.35% rate that covers less expensive vehicles.1Justia. Connecticut Code 12-408 – The Sales Tax The higher rate hits the entire purchase price, not just the amount over $50,000. Cross the threshold by a single dollar and your tax bill jumps on the full amount.
The $50,000 Threshold and Why One Dollar Matters
The statute uses the term “sales price,” meaning the actual transaction price you agree to pay. MSRP is not the reference point. If a vehicle’s sticker reads $52,000 but you negotiate down to $49,900, the standard 6.35% rate applies. Once the agreed-upon price crosses $50,000, the 7.75% rate takes over on every dollar of the taxable amount.
This is a cliff, not a marginal bracket. A $55,000 vehicle is taxed at 7.75% on the full $55,000, producing a tax of $4,262.50. A $49,999 vehicle is taxed at 6.35%, yielding $3,174.94.2Connecticut General Assembly. Luxury Tax and Electric Vehicles The two vehicles are essentially the same price. The tax bills differ by more than $1,000.
If you’re shopping close to the line, negotiate hard to land below it. A dealer who moves a price from $51,000 to $49,900 isn’t just cutting $1,100 off the sticker. They’re also dropping your tax rate by 1.4 percentage points across the entire purchase.
How Trade-Ins Affect the Tax
When you trade in a vehicle, its value comes off the sales price before tax is calculated.3Connecticut State Department of Revenue Services. PS 96(10) Sales and Use Tax Trade-In Allowance and Other Procedures in Connection with Leases of Motor Vehicles But there’s a wrinkle worth understanding: whether the luxury rate applies is determined by the gross sales price before the trade-in, while the rate itself is applied to the net amount after the trade-in.
Say you buy a $60,000 vehicle and trade in your old car for $15,000. The transaction still triggers the 7.75% rate because the gross price exceeds $50,000. But that 7.75% is calculated on $45,000, producing a tax of $3,487.50 rather than $4,650 on the full price. Make sure the trade-in value appears clearly on your bill of sale. The Department of Revenue Services needs the breakdown documented to accept the reduced taxable base.
Buying Out of State
Crossing into New Hampshire or another low-tax state won’t get you around Connecticut’s luxury rate. The state imposes a use tax at the same 7.75% on any vehicle over $50,000 brought into Connecticut for registration.4Justia. Connecticut Code 12-411 – The Use Tax
Connecticut does credit you for sales tax legitimately paid to another state. Buy in a state where you paid 4%, and you’ll owe the difference between that and 7.75% when you register at the DMV.5Connecticut Department of Motor Vehicles. Sales Tax and First Time Vehicle Registrations Bring the purchase invoice and the receipt showing what you paid the other state. Without those documents, the DMV charges the full Connecticut rate with no credit.
Leased Vehicles
Leasing works differently from buying outright. You don’t pay tax on the full vehicle value at signing. The tax is collected on each monthly payment across the life of the lease. If the acquisition cost of the vehicle exceeds $50,000, the 7.75% luxury rate applies to those payments instead of 6.35%.
Trade-ins also reduce the taxable base on a lease. If you trade in a vehicle you own when entering the lease, the trade-in value comes off the total taxable lease price, and tax is owed only on what remains.3Connecticut State Department of Revenue Services. PS 96(10) Sales and Use Tax Trade-In Allowance and Other Procedures in Connection with Leases of Motor Vehicles The luxury tax burden gets spread across the term rather than landing as one large expense at signing. If you exercise a purchase option at the end of the lease, additional tax may apply on the buyout price.
Vehicles That Don’t Get the Luxury Rate
Not every expensive vehicle triggers 7.75%. The statute exempts several categories regardless of price:
- Motor vehicles with a gross vehicle weight rating over 12,500 pounds.1Justia. Connecticut Code 12-408 – The Sales Tax
- Vehicles weighing 12,500 pounds or less that are designed or used for business purposes and carry a commercial registration from the DMV.2Connecticut General Assembly. Luxury Tax and Electric Vehicles
- Vehicles used directly in the agricultural process with a valid farmer tax exemption permit, which are exempt from sales tax entirely.6Connecticut Department of Motor Vehicles. Sales Tax Calculator
The commercial vehicle exemption is narrower than it sounds. The vehicle must actually be used for business purposes and be registered as commercial with the DMV. A personal SUV that occasionally sees business use doesn’t qualify. This exemption targets delivery trucks, work vans, and similar vehicles that happen to cost more than $50,000.
A Pending Change to Watch
The Connecticut General Assembly has introduced legislation in 2026, HB 5443, that would raise the luxury threshold from $50,000 to $75,000.7Connecticut General Assembly. sHB 5443 – An Act Concerning the Sales and Use Taxes Rate for Certain Motor Vehicles As of this writing, the $50,000 threshold remains current law. If you’re shopping in the $50,000 to $75,000 range, check with the Department of Revenue Services or the DMV for the current threshold before signing anything.
