Frequently Asked Questions — Connecticut State Taxes
Does Connecticut have a state income tax?
Yes. Connecticut levies a state individual income tax in 2022. The rates and brackets shown above apply to residents filing as single or married filing jointly. No standard deduction; personal exemption phases out for high earners. Estate tax on estates over $13.61M.
How do Connecticut tax brackets work?
Like federal taxes, Connecticut uses a marginal (progressive) tax system. Only the income within each bracket is taxed at that rate — not all your income. For example, if Connecticut has a 5% top rate, you pay 5% only on income above the top bracket threshold, not on your entire salary.
What is the difference between marginal and effective tax rate in Connecticut?
Your marginal tax rate is the rate on your highest dollar of income. Your effective tax rate is your total state tax bill divided by your gross income — always lower than your marginal rate. For example, a worker at the top bracket in Connecticut may have a marginal rate of 7.0% but an effective rate several points lower due to income in lower brackets.
