How Local Sales Tax Works in Connecticut
Connecticut has no county or municipal sales tax. The 6.35% state rate applies uniformly across the state, which makes rate calculation unusually simple. Connecticut does apply higher special rates to a small number of categories, including certain luxury goods, short-term vehicle rentals and computer and data processing services.
Which Connecticut Rate Should You Charge?
Because there is a single statewide rate with no local add-ons, sourcing rarely changes the rate you charge on a Connecticut sale. The rate that matters is whether a special category rate applies to the item rather than where the buyer is.
What Connecticut Taxes — and What It Doesn’t
Groceries and prescription drugs are exempt. Connecticut taxes a comparatively broad list of services, including many repair, maintenance and business services that neighbouring states leave untaxed — so check the service list rather than assuming services are exempt.
