When you hire your first employee in South Carolina, you trigger a series of registration requirements at the federal and state level. Missing any of these steps can result in penalties, delayed payroll, and compliance headaches. This guide walks you through everything, in order.
Registration Overview
Here’s a checklist of what every new South Carolina employer needs:
- ☑ Federal Employer Identification Number (EIN)
- ☑ South Carolina state tax registration (South Carolina Department of Revenue)
- ☑ South Carolina SUI account (South Carolina Department of Employment and Workforce)
- ☑ Workers’ compensation insurance
- ☑ New hire reporting setup
- ☑ Payroll system or software
Step 1: Get Your Federal EIN
Your Employer Identification Number (EIN) is your federal tax ID. You need it for everything — federal tax filings, state registrations, opening a business bank account, and running payroll.
Apply online at IRS.gov/EIN. It’s free and you receive your EIN immediately.
Step 2: Register with South Carolina Department of Revenue
Visit the South Carolina Department of Revenue website to register for a state employer tax account. This allows you to withhold South Carolina state income tax from employee paychecks and remit it to the state.
💼 From the Payroll Desk
Don’t wait until your first payroll to register. State registrations can take days or weeks to process. Start the registration process as soon as you know you’ll be hiring.
Step 3: Register for SUI
Register for a State Unemployment Insurance account through the South Carolina Department of Employment and Workforce. You’ll be assigned:
- An employer account number
- Your initial SUI rate (0.55% for new employers)
- Quarterly filing requirements
SUI is an employer-paid tax on the first $14,000 of each employee’s wages. See our South Carolina SUI Rates 2026 guide for details.
Step 4: Workers’ Compensation Insurance
Most South Carolina employers are required to carry workers’ compensation insurance, which covers employees who are injured on the job. Requirements vary by state — some states require coverage from the first employee, while others have minimum thresholds.
You can obtain workers’ comp through private insurance carriers or, in some states, through a state fund. Compare quotes from multiple carriers to find the best rate for your industry classification.
Starting a Business?
If you’re also forming your business entity, consider ($39 + state fee) or for LLC/corporation formation.
Step 5: New Hire Reporting
Federal and South Carolina law require you to report every new hire within 20 days of their start date. This information is used to enforce child support orders and prevent fraud.
Most states allow online reporting through their new hire reporting website. See our New Hire Reporting guide for details.
Step 6: Set Up Payroll
With all registrations complete, you’re ready to set up your payroll system. For South Carolina small businesses, we recommend:
- — Best overall for small businesses. Automated tax filings, easy setup, starting at $40/mo + $6/employee.
- — Best for growing teams with dedicated support needs.
- — Best if you already use QuickBooks for accounting.
