New Jersey paycheck calculator 2026
This New Jersey paycheck calculator estimates paycheck withholding only and does not calculate final tax liability. Federal income tax withholding follows IRS rules based on Form W-4 (2020+) and IRS Publication 15-T, and FICA covers Social Security and Medicare. New Jersey state payroll withholding is administered using official tables and methods that are not reproduced here, so state withholding shown by this tool is an estimate.

How it works
This paycheck estimate for New Jersey uses gross earnings and pay frequency as inputs prior to applying federal income tax withholding. Federal income tax withholding is estimated using IRS Publication 15-T methods tied to Form W-4 (2020+), and FICA includes Social Security and Medicare payroll taxes. New Jersey employers determine state withholding using official withholding tables and methods that depend on filing status, allowances, and pay frequency, so this tool presents the state portion as an estimate.
Examples
For a given paycheck, the calculator estimates reductions from gross pay based on federal withholding and FICA. New Jersey state withholding for regular wages relies on official tables and methods, so estimated take-home pay may differ from an employer-issued pay stub.
Limitations and important notes
This tool provides an estimate of paycheck withholding only and does not reproduce New Jersey’s official withholding tables, allowance values, or percentage-method calculations. Results may differ materially from actual payroll withholding. The estimate is not final tax liability.
