What is the difference between federal and state payroll taxes?

Understanding the Difference Between Federal and South Carolina State Payroll Taxes

Payroll taxes are essential for business operations and compliance in South Carolina. They consist of both federal and state components, each serving different purposes and requiring distinct management.

Federal Payroll Taxes

• Purpose: Federal payroll taxes fund Social Security, Medicare, and federal unemployment insurance programs.
• Components: Employers and employees share Social Security and Medicare taxes, collectively known as FICA taxes. Employers also pay Federal Unemployment Tax Act (FUTA) taxes separately.
• Reporting and Payment: Employers report federal payroll taxes to the IRS using forms such as 941 or 944 and deposit payments electronically according to IRS schedules.

South Carolina State Payroll Taxes

• Purpose: State payroll taxes primarily fund state unemployment insurance and other state-specific workforce programs.
• Components: South Carolina requires employers to pay state unemployment insurance (SUI) taxes based on assigned rates. There is no state-level income tax withholding for unemployment, but employers must withhold state income taxes from employee wages.
• Reporting and Payment: Employers register with the South Carolina Department of Employment and Workforce (DEW) for unemployment tax accounts and report wages quarterly. State income tax withholding is reported and paid to the South Carolina Department of Revenue (SCDOR) regularly.

Operational Considerations for South Carolina Employers

• Registration: Register separately with federal agencies (IRS) and state agencies (SCDOR and DEW) to handle payroll tax obligations.
• Recordkeeping: Maintain accurate payroll records to support federal and state tax filings and audits.
• Compliance: Stay updated on tax rates and filing deadlines to avoid penalties. As of 2026, tax rates and reporting requirements may change.
• Automation: Use payroll software that integrates both federal and South Carolina state tax calculations and filings to streamline compliance.
