What Is the Sales Tax Rate in Connecticut?
Connecticut charges a flat 6.35% state sales tax on most purchases, and that's the whole story. Cities and towns cannot add their own local sales tax on top, so the rate you pay in Hartford is the same rate you pay in a small shoreline town. That makes Connecticut simpler to plan around than most states, similar to how Massachusetts keeps a single statewide rate.
USACalculator built this Connecticut version because there's no city selector to worry about here. Enter a purchase price and the flat rate applies automatically, every time.
Using the Calculator
Connecticut is preselected in the dropdown with its 6.35% flat rate already loaded. Enter the price of what you're buying and the total updates immediately, since there's no local rate variation to account for. Planning a bigger purchase, like a vehicle? Check our Connecticut Car Loan Calculator, which factors in vehicle-specific tax rules.
How the Calculation Works
The formula is simple: multiply your purchase price by 6.35% to get the tax owed, then add that to the original price for your total. Because Connecticut has no local add-on anywhere in the state, this single multiplication gives an accurate answer regardless of which city or town the sale happens in.
Connecticut-Specific Sales Tax Information
State Sales Tax
The rate is 6.35% statewide, set by the Connecticut Department of Revenue Services and applied to most tangible goods and many services.
No Local Sales Tax
Unlike states where cities and counties stack their own rate on top of the state number, Connecticut law does not allow any local sales tax. The 6.35% figure is the final rate almost everywhere, which removes a layer of guesswork other states require.
Combined Rate
Since there's no local add-on, the combined rate is simply 6.35% statewide, one of the more predictable sales tax environments in the country for both shoppers and small business owners.
Tax Exemptions
Most unprepared grocery food and prescription medications are exempt from Connecticut sales tax. Some items, including certain clothing and footwear, have carried exemptions or reduced treatment at various points, so it's worth checking current Department of Revenue Services guidance before assuming an item is taxed the standard way.
Example Calculation
Say you're buying a $250 item anywhere in Connecticut. The math looks like this:
| Item | Amount |
| Purchase Price | $250.00 |
| Sales Tax (6.35%) | $15.88 |
| Total Price | $265.88 |
Buy the same item in a different Connecticut town, and the total stays exactly the same, since there's no local rate to shift the number up or down.

Common Mistakes to Avoid
- Assuming a local add-on exists, the way it does in many other states. Connecticut's rate is flat statewide.
- Forgetting to check current exemption rules for clothing and footwear, which have shifted over time.
- Treating grocery exemptions as covering restaurant meals or prepared hot food, which stay taxable.
- Assuming all vehicle purchases use the standard rate without checking rules for higher-value vehicles.
