Connecticut Income Tax Overview

Connecticut runs a progressive income tax with seven brackets, starting at 3% on the first slice of income and rising to a top rate of 6.99%. Only the dollars that fall inside each bracket are taxed at that bracket's rate, so reaching the top tier does not push your whole income to 6.99%. The Department of Revenue Services administers the tax, and most workers prepay it through paycheck withholding before reconciling on the Form CT-1040 each spring.

This state tax sits entirely on top of your federal bill rather than replacing any of it. Connecticut leans on a personal exemption that phases out as income rises instead of a standard deduction, and it layers in a recapture provision that nudges effective rates upward for high earners. Residents owe Connecticut tax on income from everywhere, while nonresidents who work in the state generally owe only on income earned here.

Connecticut Income Tax FAQ

What is Connecticut's top income tax rate?
The highest marginal rate is 6.99%, the top of a progressive schedule that begins at 3%. Because the brackets are marginal, only income above the top threshold is taxed at 6.99%; the rest is taxed at the lower rates that apply to the brackets beneath it.
Does Connecticut have a standard deduction?
No. Instead of a standard deduction, Connecticut uses a personal exemption that shrinks as income rises and phases out entirely at higher incomes. This is one reason a Connecticut return looks different from the federal return, where a standard deduction is the norm.
How does Connecticut income tax stack with federal tax?
They are separate and additive. You first owe federal income tax to the IRS, and then Connecticut applies its own rates on top through the Department of Revenue Services. The state tax does not reduce your federal tax, so your total income tax burden is the sum of both.
What is the Connecticut tax recapture provision?
Recapture is a feature that gradually claws back the benefit of the lower brackets for higher earners, effectively pushing their average rate closer to the top marginal rate. It means a high-income filer ends up paying more than a simple bracket calculation alone would suggest.
