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: Social Security is 6.2% up to the 2026 wage base of $184,500, Medicare is 1.45% on all covered wages, and Additional Medicare Tax of 0.9% is withheld after wages exceed $200,000 in the calendar year. South Carolina's 2026 withholding uses the WH-1603F annual formula path with graduated brackets at 0%, 3%, and 6% after personal allowances and standard deduction. H.4216, signed March 30, 2026, would change rates to 1.99% below $30,000 and 5.21% above (minus $966) for tax year 2026, but that structure is not yet reflected in this calculator's engine data. South Carolina does not have a separate statewide employee SDI or paid family leave payroll deduction. Estimates assume standard 2026 withholding, single filing status, and no pre-tax deductions; actual paycheck may differ.
