How sales tax works in Connecticut
Connecticut levies a single statewide 6.35% rate with no local sales taxes, so the rate is the same everywhere in the state. Certain goods carry different rates — for example a 7.75% luxury rate on expensive vehicles, jewellery and clothing over a threshold.
Rates are the Tax Foundation’s figures as of January 1, 2026. Local rates change and vary by address; confirm the exact figure with the Connecticut department of revenue or a rate lookup by ZIP code before relying on it.

Method & sources
State base rates come from each state’s department of revenue; average combined (state + local) rates are population-weighted figures published by the Tax Foundation, as of January 1, 2026. Local rates can change every quarter and can differ between neighbouring ZIP codes, so treat the combined rate as an estimate and confirm the exact rate for a delivery address with the state revenue department.
Sales tax is applied to the price after any store discount. Manufacturer coupons and rebates are handled differently from state to state.
