How Connecticut Sales Tax Works

Connecticut charges a 6.35% state sales tax rate. On top of that, local jurisdictions (counties, cities, special districts) add their own taxes, bringing the average combined rate to 6.35%. That means on a $1,000 purchase, you'd pay approximately $63.50 in sales tax for a total of $1063.50.
The Connecticut state rate of 6.35% applies uniformly across the state, and there are no local sales tax additions. This makes the calculation straightforward — the state rate is what you pay everywhere.
Good news: Connecticut exempts groceries, prescription drugs, clothing from state sales tax. These exemptions can make a real difference in your annual spending, especially on groceries which are a recurring expense for every household.
Need to work backwards? If you have a total receipt and need to find the original price before tax, use the reverse sales tax formula: divide the total by (1 + tax rate). For example, a $1063.50 total with 6.35% tax means the original price was $1,000 ($1063.50 ÷ 1.635). This is useful for expense reports and bookkeeping.
Since the 2018 South Dakota v. Wayfair Supreme Court decision, online retailers must collect Connecticut sales tax on purchases shipped to CT residents. Most online purchases now include Connecticut sales tax based on the buyer's location, including any applicable local taxes.
