How Your SC Paycheck Works
South Carolina paychecks include federal income tax withholding calculated using Form W-4 and IRS Publication 15-T.
FICA applies separately under the current IRS and SSA payroll rules encoded in the tax data bundle.
South Carolina employer withholding follows SCDOR Form WH-1603F for 2026. The formula uses the employee's SC W-4 allowance count to determine whether personal-allowance and standard-deduction adjustments apply before the source-backed withholding brackets.
South Carolina does not have a separate statewide employee SDI or paid family leave payroll deduction. Actual paycheck withholding may differ if payroll inputs do not match the employee's SC W-4.
