Connecticut Car Sales Tax Calculator – Fast, Free & Accurate

How Connecticut Car Sales Tax Works

Connecticut applies a state sales tax on vehicle purchases. The rules are straightforward, but with a few important details:

• Standard Rate: 6.35% applies to most vehicles under $50,000.
• Luxury Rate: 7.75% applies if the vehicle price is over $50,000.
• Trade-in Deductions: If you trade in a car, the trade-in value is subtracted from the purchase price before the tax is applied.
• Taxable Amount: The tax is only calculated on the net amount after subtracting trade-in value.

Example:
If you buy a $55,000 SUV and trade in a car worth $10,000:

• Taxable amount = $55,000 – $10,000 = $45,000
• Since the price is above $50,000, the luxury tax rate (7.75%) applies.
• Estimated tax = $45,000 × 7.75% = $3,487.50

• Avoiding Surprises – No last-minute shock at the dealership when taxes get added to your bill.

For example, two cars priced $49,500 vs. $50,500 may seem close, but the second one triggers the luxury tax rate—adding hundreds more in tax.
