South Carolina uses a simplified three-tier income tax with a 0% bottom band and a 6% top rate. This South Carolina paycheck calculator combines federal income tax, Social Security, Medicare, and SC state income tax to show your real 2026 take-home pay.
How South Carolina state income tax works
South Carolina exempts the first $3,640 of taxable income, applies 3% from $3,640 to $18,230, and 6% on income above $18,230. The same thresholds apply to both single and joint filers — South Carolina does not double brackets for married filing jointly.
South Carolina offers a state standard deduction of $8,350 single / $16,700 joint, which the calculator subtracts from your wage base before applying brackets. Combined with the 0% bottom band, lower earners pay a meaningfully lower effective rate than the 6% top rate suggests.
