Sales tax calculator
This webpage is to assist out-of-state dealers (not licensed in Connecticut) and third-party titling services to calculate the sales tax that is due when they mail in the transactions to DMV's Vehicle and Business Regulation office for processing. The sales tax calculator should be used on every out-of-state dealer transaction. (Please note: this does not apply to leased vehicles.)
Please note: Cap cost reductions and cash down payments are not listed as taxable items since they are already included in the purchase price of the vehicle.
Tax rates:
- Sales tax is charged at a rate of 6.35% (vessels and trailers that transport vessels are at 2.99% sales tax rate), except for those vehicles that are exempt from sales tax.
- Sales tax is charged at a rate of 7.75% for any vehicle registered as passenger or combination when the total cost of the vehicle more than $50,000.
- When any of the below taxable items are added to the selling price of the vehicle and it brings the vehicle selling price over $50,000, the sales tax rate of 7.75% is charged.
