Does South Carolina have daily overtime?
No. Like most states, South Carolina follows the federal standard: overtime is owed only after 40 hours in a workweek, not for long single days, weekends, or holidays by themselves. Four states — California, Alaska, Nevada, and Colorado — add daily overtime; South Carolina is not one of them. Employer policy or a union contract can still provide extra premiums.
The federal rule that always applies in South Carolina
Under the federal Fair Labor Standards Act (FLSA), covered non-exempt employees in South Carolina must be paid at least 1.5 times their regular rate for every hour worked over 40 in a workweek. The math is two steps: overtime rate = regular rate × 1.5, then overtime pay = overtime rate × overtime hours. The authoritative federal reference is the U.S. Department of Labor overtime page. Rules change — confirm anything time-sensitive with South Carolina's state labor department before relying on it.
No tax on overtime in South Carolina
Overtime has never had a special higher tax rate — it is ordinary income. And under the 2025 federal law commonly called “no tax on overtime,” eligible workers in South Carolina can deduct the premium portion of FLSA overtime (the extra 0.5x) from federal taxable income, up to annual caps, for tax years 2025 through 2028. Because it is federal, it applies in South Carolina the same as every other state. Estimate what it is worth with the no tax on overtime calculator.
