How South Carolina State Income Tax Works

South Carolina underwent a major tax reform with H. 4216 (Act 110), signed into law on March 30, 2026, effective for the 2026 tax year. The law replaced the previous three-bracket system (0%/3%/6%) with a simplified two-rate structure. Taxpayers are subject to a 1.99% rate on the first $30,000 of taxable income and a 5.21% rate on taxable income above $30,000.

The law also decoupled South Carolina from federal deductions by starting with federal Adjusted Gross Income (AGI) rather than federal taxable income. A new South Carolina Income Adjusted Deduction (SCIAD) replaces the federal standard deduction: $15,000 for single filers, $22,500 for head of household, and $30,000 for married filing jointly. The SCIAD phases out at higher income levels.

Key features of South Carolina state income tax:

  • Two-rate structure: 1.99% on income up to $30,000, 5.21% on income over $30,000
  • New SCIAD deduction replaces federal standard/itemized deductions
  • Starting point is federal AGI (not federal taxable income)
  • Future rate reductions tied to state revenue growth
  • State EITC capped at $200

Federal Tax and FICA Deductions

This calculator applies the 2026 federal income tax brackets based on your filing status. The standard deduction for 2026 is $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for head of household. FICA taxes include Social Security at 6.2%, Medicare at 1.45%, and Additional Medicare at 0.9% for high earners.

Pre-Tax Deductions

Contributions to a traditional 401(k), HSA, and pre-tax health insurance premiums reduce your taxable income. This calculator accounts for these deductions to give you a more accurate take-home pay estimate.

How This Is Calculated

This calculator is based on 2026 IRS federal tax brackets and FICA, plus South Carolina's new two-rate income tax structure under H. 4216.
