  • 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.
