Connecticut sales tax rate
Connecticut's sales and use tax rate is 6.35% statewide on 2026-10-22 (general rate, from the Connecticut Department of Revenue Services). There is no general local sales tax, so it is the general rate at every address in Connecticut; special rates (such as meals or lodging) are not included.
A published rate is not the tax due on a sale: taxability, sourcing, nexus and exemptions all change what is owed.

- These are published sales and use tax rates by jurisdiction. They are not the tax due on a transaction and not a taxability determination: whether an item is taxable, which location's rate applies (sourcing), whether the seller must collect (nexus) and any exemption all change what is owed. Rates come from the Streamlined Sales Tax files the states publish or, where a result's source says so, from the state revenue department's own files and pages; confirm with the state before relying on them.
- Connecticut: one statewide rate (6.35%); there are no local sales taxes. Meals (7.35%), luxury items (7.75%) and other special rates are not returned.
- Boundary from Census, rate from the state: the county (or state) was found from the ZIP's Census 2020 ZIP Code Tabulation Area, not from the state. ZCTAs approximate USPS ZIP areas; a ZIP that crosses a county line returns one candidate per county set with its land share, and PO-box or unique ZIPs have no ZCTA. Confirm the county for an address near a county line.
