South Carolina restructured its income tax for 2026 under Act 110 (H.4216). Income up to $30,000 is taxed at 1.99%, and income above that at 5.21%. It replaced the federal standard deduction with a new SC Income Adjusted Deduction of $15,000 single / $30,000 married-jointly that phases out at higher incomes.
Note on 2026 figures: The SC Income Adjusted Deduction phases out with income (single $40,000 to $95,000, head of household $60,000 to $142,500, joint $80,000 to $190,000). The full deduction is used here; taxpayers above those ranges receive a smaller amount.
