Connecticut Paycheck Tax Calculator
Connecticut uses a progressive income tax system with multiple brackets, reaching a top rate of 7.0% for high earners. Like the federal system, you only pay each rate on the income within that bracket — not on your entire income. Connecticut also offers a standard deduction that reduces your taxable income before brackets are applied. In addition to state income tax, Connecticut workers pay federal income tax at rates between 10% and 37%, plus 6.2% Social Security and 1.45% Medicare. Pre-tax deductions such as 401(k) contributions, health insurance, HSA, and FSA contributions reduce your taxable income and lower your overall tax burden.

How Connecticut paycheck taxes work
In addition to federal taxes, Connecticut workers have state income tax withheld from each paycheck. Connecticut uses progressive brackets — you pay a lower rate on your first dollars and a higher rate only on income above each threshold.
Federal income tax is also withheld, using 2025/2026 brackets from 10% to 37%. The federal standard deduction ($14,600 single, $29,200 MFJ) is separate from any Connecticut state deduction.
