Connecticut income tax at a glance
Connecticut has no standard deduction; its personal exemption phases out completely by $45,000 of AGI for single filers ($72,000 joint). Higher earners lose the benefit of the 2% bracket and pay “benefit recapture” amounts, so many high-income taxpayers effectively pay their top rate on all income. The low-income personal tax credit (1%–75%) is not modeled.

How Connecticut calculates your income tax
Connecticut starts from your federal adjusted gross income (AGI). There is no standard deduction in Connecticut. You also get a personal exemption of $15,000 ($24,000 joint).
- The personal exemption phases out between $30,000 and $45,000 of AGI for single filers.
- Above about $56,500 of AGI ($100,500 joint) the 2% bracket is phased out and recapture amounts are added; the calculator models both.

How to lower your Connecticut income tax
- Pre-tax retirement savings. Putting $10,000 into a traditional 401(k) on a $75,000 salary cuts Connecticut tax by about $600 on top of the federal savings.
- Claim state credits. Check the Connecticut return for earned-income, child, education and renter or property-tax credits that this estimate doesn’t include.
- Watch residency and work location. Days worked in another state and the date you move in or out change how much each state can tax.
- Time large income. Bonuses, stock sales and Roth conversions all land on your state return too.
