Connecticut paycheck calculator 2026
This Connecticut paycheck calculator estimates paycheck withholding, not final tax liability. Connecticut wage withholding is determined using official withholding tables and calculation rules that depend on pay frequency and employee inputs (such as the Connecticut withholding code). Because those tables and multi-step rules are not reproduced here, Connecticut state withholding is shown in estimate-mode.

How it works
Connecticut paycheck estimates are calculated from gross pay for the selected pay period using federal withholding methods defined by the IRS. Federal income tax withholding follows IRS Publication 15-T and Form W-4 (2020+) inputs, and FICA covers Social Security and Medicare payroll taxes. Connecticut state wage withholding is normally computed using state withholding tables and calculation rules that annualize wages and apply table-driven steps based on the employee’s Connecticut withholding inputs, then convert the result back to a per-paycheck amount. This calculator does not reproduce those official tables and multi-step rules.
Examples
A biweekly paycheck estimate typically includes federal income tax withholding and FICA withheld from gross pay. Connecticut state withholding can vary materially for the same annual salary because official withholding depends on the employee’s Connecticut withholding inputs and pay frequency tables.
Limitations and important notes
Results are estimates of paycheck withholding and are not final tax liability or an exact match to an employer payroll system. Connecticut state withholding is shown in estimate-mode because official guidance relies on pay-frequency tables, withholding codes, and multi-step calculation rules that are not reproduced here. This calculator does not include any county, city, or municipal income taxes.
