Mississippi paycheck calculator 2026
This Mississippi paycheck calculator estimates paycheck withholding, not final tax liability. Federal withholding follows IRS Publication 15-T and Form W-4 (2020+), and FICA covers Social Security and Medicare. Mississippi state withholding is shown in estimate-mode because official guidance relies on pay-frequency tables and exemption-based adjustments that are not reproduced here.

How it works
A paycheck withholding estimate starts from gross pay for the selected pay frequency. Federal income tax withholding is calculated using IRS Publication 15-T with Form W-4 (2020+) inputs, and FICA payroll taxes include Social Security and Medicare. Mississippi requires employers to withhold state income tax from wages using official withholding tables that vary by payroll period and depend on the employee’s Mississippi exemption certificate and statutory adjustments.
Examples
With weekly or biweekly pay, federal withholding and FICA are estimated for that pay period based on your inputs. Mississippi withholding, in practice, is determined using the official table for the payroll period and the employee’s exemption information, so it does not reduce to a single flat percentage of gross wages.
Limitations and important notes
Mississippi state withholding for regular wages is not modeled numerically in this calculator. Official guidance uses pay-frequency withholding tables and exemption-based adjustments, and no general single flat rate is authorized for regular wages. As a result, this tool does not reproduce the official Mississippi withholding tables or output a numeric Mississippi state withholding amount. Actual withholding may differ materially from these estimates. This calculator does not include any local, county, or municipal wage or income taxes.
