How it works
Enter your pay and what’s on your W-4 to see each paycheck after taxes in Connecticut. Federal income tax is figured with the IRS percentage method for 2026, the same tables payroll software uses, plus Social Security (6.2%) and Medicare (1.45%).
Connecticut uses the withholding code on your CT-W4. Your code sets a personal exemption that phases out as pay rises, the rate table (2% to 6.99%), two add-backs for higher earners, and a personal credit of up to 75% of the tax for lower earners. Your paycheck also shows CT Paid Leave, which is withheld for state programs.
Traditional 401(k) and 403(b) contributions lower your federal and Connecticut income tax but not Social Security and Medicare. Pre-tax health insurance and HSA payroll contributions lower all of them.
Withholding is an estimate of your tax, paid as you go. Whether you get a refund depends on your full-year income, deductions and credits; the tax refund calculator estimates that. To compare states, use the paycheck calculator.
Formula
Take-home = gross pay − federal withholding − Social Security − Medicare − Connecticut withholding − state payroll programs − pre-tax deductions

Questions people ask
How much Connecticut income tax comes out of a $60,000 salary?
About $89.13 per paycheck, or $2,318 a year, for a single filer paid every two weeks with the default allowances. Take-home pay comes to about $1,837.40 per paycheck after federal tax, Social Security and Medicare as well.
Does Connecticut have local income taxes?
No. Connecticut cities and counties don’t tax wages, so your paycheck has only federal and state withholding.
Why is my real paycheck different?
Employers round to the cent or dollar, some benefits change which wages are taxed, and bonuses are often withheld at a flat supplemental rate. Social Security also stops for the year once your wages pass $184,500. Use your pay stub to check, and this page to see how a change would affect it.
