How Your CT Paycheck Works

Connecticut paychecks begin with federal income tax withholding under IRS Publication 15-T, using the employee's Form W-4, taxable wages, payroll period, and IRS withholding tables. FICA is separate: employees pay 6.2% Social Security tax up to the 2026 wage base of $184,500, plus 1.45% Medicare tax on all covered wages, and employers withhold an additional 0.9% Medicare surtax after an employee's Medicare wages exceed $200,000 in a calendar year. Connecticut uses its own Form CT-W4 withholding code system. The 2026 DRS calculation rules annualize wages, subtract the applicable personal exemption, and apply Connecticut's graduated income tax rates from 2.00% to 6.99%, with a tax-rate phase-out and recapture for higher incomes. Connecticut also has a statewide employee payroll deduction for CT Paid Leave: the 2026 contribution rate is 0.5% of pay, applied until the employee reaches the Social Security contribution limit of $184,500. CT Paid Leave is not included in this calculator's withholding computation. Estimates assume standard 2026 withholding, single filing status, and no pre-tax deductions; actual paycheck may differ.
