Understanding Sales Tax in Connecticut
Connecticut has a statewide sales tax rate of 6.35% with no local sales taxes added on top. This makes Connecticut unusual among US states — its total combined rate is simply the state rate of 6.35% everywhere in the state. There is no county or city sales tax, and there are no special district sales taxes in Connecticut.
The simplicity of Connecticut's system makes it one of the easiest states for both businesses and consumers to navigate. Every sale in Connecticut — from Bridgeport to Hartford to New Haven — is subject to the same 6.35% rate. This eliminates the confusion of different rates for different cities that plagues states like California, Texas, or Colorado.
Connecticut applies several special rates for specific goods. Motor vehicles are taxed at 6.35% on the first $50,000 of purchase price, but the excess above $50,000 is taxed at 7.75%. Luxury goods priced above $50,000 (boats, jewelry, clothing, and furniture) are also subject to a higher 7.75% rate. This progressive luxury tax structure is somewhat unique among US states.
Most essential goods are exempt from Connecticut sales tax: food for human consumption (not restaurant meals), prescription drugs, and residential energy fuels. Services are generally not taxable in Connecticut, but there are exceptions for services such as telecommunications, computer and data processing, and certain digital services.
The Connecticut Department of Revenue Services (DRS) administers the state sales tax. Returns are typically filed monthly for large sellers and quarterly or annually for smaller businesses. Connecticut is known for being an active sales tax auditor, particularly for businesses in retail, hospitality, and the service sector.
