Connecticut Paycheck Calculator
Work out Connecticut take-home pay from gross, pay frequency, filing status and pre-tax deductions. Federal and FICA are estimated for you; enter the CT...
Estimate pay before Connecticut state and local withholding, then enter the amount from current official state guidance.
Connecticut state withholding is not calculated automatically. Enter the amount for this pay period from an official worksheet or genuine payroll record to include it; leave it blank to see pay before state withholding. You can enter a known local withholding amount separately. Only federal withholding and FICA are estimated on this page; Connecticut income tax withholding and the paid family and medical leave contribution appear solely as amounts you supply from a pay statement or from the Department of Revenue Services' published calculation rules. This calculator is an estimate workspace, not a payroll filing service. Verify every assumption with current official instructions.
Why a Connecticut figure cannot be produced here
The Department of Revenue Services sets out how employers calculate Connecticut withholding in its Withholding Calculation Rules, Form TPG-211, and in the Circular CT employer's tax guide. That method annualizes wages and then works through several tables keyed to the withholding code an employee reported: an initial tax calculation, a phase-out add-back, a recapture amount and a personal tax credit factor applied at the end. This page asks for a filing status, not a withholding code, and runs none of those tables. The Connecticut field stays empty unless you enter a pay period amount from payroll or from the published rules.
The paid leave contribution sits outside the tax line
A second Connecticut deduction is missing from the estimate for the same reason: the paid family and medical leave contribution, administered by the Paid Family and Medical Leave Insurance Authority. It is not income tax, so it does not belong in the Connecticut withholding field. Put it under other deductions, using the amount printed on a statement for the same pay period, and it comes off the estimate once. Changing the pay frequency here empties the boxes you filled in, which is deliberate: a monthly contribution left sitting beside weekly gross pay would quietly overstate what comes out of the check.
Frequently asked questions
What exactly goes in the Connecticut withholding field?
One pay period's Connecticut income tax withholding, copied from a genuine pay statement or worked out from the Department of Revenue Services' Withholding Calculation Rules for the year concerned. Do not enter a year-to-date total, and do not fold in the paid family and medical leave contribution. If you leave the field empty, the heading above the result says so plainly: the figure shown is pay before Connecticut withholding, not take-home pay.
Why does changing my filing status not move the Connecticut number?
Because Connecticut withholding is driven by the withholding code an employee reports to the employer on Form CT-W4 and by the tables the Department of Revenue Services publishes around it, none of which this page implements. The filing status you pick here feeds the federal estimate only. That is also why two people with the same gross pay and the same filing status can see different Connecticut amounts on their real statements.
