What's in the Connecticut rate file
Connecticut data ships inside every edition — we do not sell single-state files. Each row carries the ZIP code, county and city name, the rate at each jurisdiction level, the combined total, and whether shipping is taxable. The higher editions add district reporting codes, FIPS codes, effective dates and sales tax holiday windows.

How local tax works in Connecticut. No local sales taxes exist in Connecticut. DRS administers a single statewide tax.
Worth knowing. No rate lookup because there is no local tax, but the single 6.35% rate is overlaid with statutory special rates — 1% on computer and data processing services, 7.35% on meals, 7.75% on luxury goods, 9.35% on short-term vehicle rental.
Questions
Connecticut sales tax questions
What is the sales tax rate in Connecticut?
The statewide base rate is 6.35%. Connecticut has no local sales taxes, so the statewide rate is the rate everywhere — one of the few states where that is true.
Is shipping taxable in Connecticut?
Generally yes. In Connecticut a delivery charge is taxable whether you bill it on its own or roll it in with handling.
That distinction catches people out, which is why our file carries both flags — TAX_SHIPPING_ALONE and TAX_SHIPPING_AND_HANDLING_TOGETHER — on every row, for the specific jurisdiction. Your system doesn't have to encode the rule.
How many sales tax jurisdictions are there in Connecticut?
None — Connecticut has no county, city or district sales taxes, so the state rate is the entire rate across all 422 CT ZIP codes. That is rare, and it is why a single statewide number is safe here and almost nowhere else.
