How North Carolina Sets Workers' Compensation Rates
North Carolina workers' compensation rates are determined by the State Workers' Compensation Insurance Rating Bureau (SWCIRB) using a classification system that matches job duties to risk categories. Employers report payroll by class code, and the bureau applies a base rate that reflects the average cost of claims for that occupation. The final premium equals the base rate multiplied by the employer's payroll, adjusted for experience rating, state assessments, and any applicable discounts.

Key Factors That Influence the Rate
Several variables shape the final rate for each employer:
- Classification code: Each job type has a specific code and associated base rate.
- Payroll size: Larger payrolls increase the premium proportionally.
- Experience modification factor (EMR): Employers with fewer or less severe claims receive a lower EMR, reducing their rate.
- State assessments: The NC Department of Labor adds a fixed assessment per $100 of payroll.
- Discounts and surcharges: Safety programs, voluntary compliance, or high-risk activities can adjust the rate.
Current Base Rate Table (2024)
The table below lists the most common classification codes and their 2024 base rates per $100 of payroll. Rates are subject to annual review.
| Class Code | Occupation | Base Rate (2024) |
|---|---|---|
| 8810 | Clerical Office Employees | $0.38 |
| 8742 | Construction – General | $2.15 |
| 8815 | Retail Salespersons | $0.62 |
| 8743 | Construction – Heavy & Highway | $3.45 |
| 8816 | Food Service Workers | $0.79 |
Calculating Your Employer Premium
To estimate the premium, follow these steps:
For example, a retailer with $200,000 payroll classified under 8815 and an EMR of 0.92 would calculate: ($200,000 ÷ 100) × $0.62 = $1,240 base premium; $1,240 × 0.92 = $1,140.80 adjusted; plus $140 assessment = $1,280.80 before discounts.
Where to Find Official Rate Information
The North Carolina Department of Labor publishes the annual workers' compensation rate book on its website. Employers can also access up‑to‑date tables through licensed insurance carriers or the SWCIRB portal. Regularly reviewing these sources ensures compliance and helps identify opportunities to lower costs through safety initiatives.
