History & Fun Facts

Connecticut sales and use tax was first imposed effective July 1, 1947.

  • Connecticut is unusual in that it imposes a “luxury goods” tax on specified purchases. The tax rate on luxury goods is 7.75% and applies to sales of motor vehicles over $50,000, jewelry over $5000, and clothing, footwear and accessories over $1000 (information current as of August 2022)
  • At 7 days long, Connecticut’s annual back-to-school sales tax holiday runs much longer than the typical 2-3 days that you see in most other states with sales tax holidays.
  • Connecticut has an emphasis on safety. Safety apparel such as protective equipment or clothing including car seats and bicycle helmets are tax exempt.
