What the numbers mean
For ordinary taxable purchases, you generally do not need to choose between a state average and a city rate. The 6.35% statewide rate is the main number to use, though product exemptions and special taxes can still change a receipt.
Connecticut's 6.35% combined rate ranks #33 from highest to lowest among the 50 states. The absence of a general local add-on makes reverse calculations more consistent across the state.
Confirm product exemptions and exact local rates before filing or billing.
