How Connecticut Sales Tax Works
Sales tax in Connecticut is collected at the point of sale on most tangible goods and some services.

Certain items like groceries and prescription medications may be exempt or taxed at reduced rates.

What Is and Is Not Taxed in Connecticut
Unprepared groceries are exempt from Connecticut state sales tax — meals and prepared food are taxed at a higher 7.35% rate.
Prescription medicines are exempt in Connecticut, as they are in every state that levies a sales tax; over-the-counter drugs and most medical supplies are treated separately and are frequently taxable.
Out-of-state sellers must register and collect Connecticut tax once they cross the state's economic nexus threshold, a rule that follows from the 2018 Supreme Court decision in South Dakota v. Wayfair. Below that threshold, the buyer technically owes use tax instead.
