Paying unemployment insurance (UI) in South Carolina
On top of withholding federal taxes such as Medicare and Social Security taxes, you are also responsible for withholding and paying certain South Carolina state taxes from your employee’s payroll. These taxes together are referred to as employer payroll taxes or payroll withholding. One of the taxes you will need to pay is unemployment insurance (UI).
Unemployment insurance is a national program administered by the US Department of Labor. The program provides temporary payments to people who are unemployed through no fault of their own. Employers can manage their South Carolina unemployment insurance through the online portal.
For more information on paying your unemployment insurance, refer to the South Carolina Department of Employment and Workforce.
South Carolina state unemployment insurance (SUI) tax rates
South Carolina’s unemployment insurance rates are determined annually based on the employer’s experience rating and the state’s Unemployment Insurance Trust Fund balance. Employers can access their specific tax rates through the South Carolina Department of Employment and Workforce’s online portal.
Experience rating | Minimum rate | Maximum rate |
---|---|---|
New employer | 0.55% | 2.35% |
Lowest rate | 0.06% | 0.06% |
Highest rate | 5.46% | 5.46% |
Employers are responsible for paying unemployment insurance contributions based on these rates. Contributions help maintain the unemployment fund, supporting employees in times of job loss.
Withholding personal income tax from your South Carolina employee
Employers are also responsible for withholding certain South Carolina state taxes from their employee’s payroll. Personal income tax, also known as individual income tax or state income tax, is a tax on the income of South Carolina residents. Employers must deduct the tax from the employee’s wages and withhold it.
After you withhold the tax from your employee, you are responsible for paying the amount you withheld to the state. You can file and pay the withholding amount online.
For more information on paying the withholding amount, refer to the South Carolina Department of Revenue.

Workers’ compensation is a type of insurance that covers wages and medical benefits for employees who are injured while performing their job. The state of South Carolina provides information online to help you find a qualified commercial carrier. Employers should verify that their workers’ compensation insurance complies with the state’s regulations for workers’ compensation.
