Can I pay the lower 6.35% rate?

You can buy a car under $50,000 to calculate lower tax, but remember tangible products like car alarms will affect the sales tax rate in CT. If the car is $49,750 and the alarm is $300, then the sales tax rate would increase to 7.75% for the entire purchase. The car alarm would actually cost $879 with the additional sales tax.

Dealer document fees are added to the price for taxation so if the doc fee is $500, then the car must be $49,500 or less to qualify for the lower 6.35% tax rate.

Extended warranties and maintenance plans are always taxed at 6.35% and will not cause the tax rate to increase.
Does CT give tax credit for trade-in vehicles?

Yes. The trade vehicle value is subtracted from the taxable value in Connecticut.

For example, if the selling vehicle costs $30000 and the trade value is $10000 then the tax owed would be 6.35% of $20000, which equals $1270 tax.

Adjust the CT car tax calculator to see how the trade lowers the tax.
What is the non-resident military car tax rate in Connecticut?

Active-duty military in Connecticut that are residents of another state are taxed at 4.5%. There are no changes to the rate over $50,000 for out-of-state military.
