South Carolina — 2026

OfficialValues verified

2026 brackets are a full legislative replacement under Act 110 (H.4216), independently verified against SC DOR's H.4216 guidance -- not a 2025 carry-forward. Act 110 also decoupled SC from federal taxable income and substituted the South Carolina Income Adjusted Deduction ($15,000 single, phasing to $0 between $40,000 and $95,000 of federal AGI).
