Income tax in South Carolina

  • Under Act 110 of 2026, South Carolina starts from federal AGI and taxes income at 1.99% on the first $30,000 and 5.21% above that, for every filing status.
  • Federal standard and itemized deductions no longer apply; instead the South Carolina Income Adjusted Deduction gives $15,000 single, $22,500 head of household or $30,000 joint, phasing out as federal AGI rises above $40,000, $60,000 or $80,000.
  • Social Security is exempt, and retirees can deduct up to $10,000 of retirement income at 65 or older ($3,000 under 65) plus an age 65 deduction of up to $15,000, reduced by the retirement deduction.
  • Nonrefundable credits include a state EITC of 125% of the federal credit capped at $200, a two wage earner credit for married couples, and a care credit of 7% of care expenses.
