How Connecticut paycheck tax works
Connecticut has a graduated income tax for 2026 with rates from 2% to 6.99%. Withholding is driven by a CT-W4 'withholding code' (filing status); it subtracts a personal exemption that phases down as income rises, applies the bracket tax, then multiplies by a personal tax-credit factor that lowers withholding for lower earners, with a benefit-recapture add-back for higher earners. Connecticut publishes no flat supplemental/bonus rate; bonuses are combined with regular wages for withholding.
A few other items come out of the same check. Employees pay a Connecticut Paid Leave (CT Paid Leave) contribution of 0.5% of wages, up to the Social Security wage base. It is withheld from pay but is not state income tax.
The calculator annualizes your pay, then runs Connecticut's 2026 graduated withholding alongside federal income tax and FICA. It's a close estimate rather than an exact match: your actual paycheck can differ from your employer's payroll, which may use exact per-period tables.
