South Carolina Payroll Landscape
South Carolina has been reducing its income tax rates and offers a relatively straightforward payroll environment. The state has no local payroll taxes, a moderate SUI wage base of $14,000, and one of the lowest new employer SUI rates in the country. The top income tax rate of 6% kicks in at just $18,230, meaning most employees are at the top rate.
For startups, South Carolina's simplicity is a plus. Register for withholding with the Department of Revenue and for unemployment insurance with the Department of Employment and Workforce. The state has been growing as a tech and manufacturing hub, particularly in the Charleston and Greenville areas.
This guide breaks down each of South Carolina's employer obligations: registration requirements, 2026 tax rates and wage bases, filing deadlines, and the compliance pitfalls that catch expanding startups off guard.
