About these South Carolina figures: state tax here is calculated from a compiled 2025/2026 rate table using each jurisdiction's brackets and standard deduction — not from South Carolina's own published schedule, and not every entry has been confirmed against it. Treat the result as an estimate and check anything you are relying on with South Carolina's revenue department. Federal figures come from published IRS releases and are cited on the pages that use them. See how we calculate and what has been verified.
