SC Code 42-1-360 compliance, NCCI class codes, and experience modification rates for Greenville employers
Under SC Code Section 42-1-360, every employer in South Carolina with four or more employees must carry workers compensation insurance. This is not optional. The South Carolina Workers' Compensation Commission enforces this requirement, and employers who fail to comply face fines up to $100 per day of non-compliance, personal liability for employee injuries, and potential criminal charges for willful violations.
Greenville County is home to thousands of businesses across manufacturing, construction, healthcare, hospitality, and professional services. BMW Manufacturing in Greer, Michelin's North American headquarters, Prisma Health, and hundreds of contractors and restaurants all carry workers comp coverage. If your Greenville business has four or more employees on payroll, you need a workers compensation policy.
The Morgano Agency Inc has written workers compensation policies for Greenville businesses since 1998. As an independent insurance agency, the firm works with multiple workers comp carriers to find the most competitive rate for your industry classification and claims history.
Every workers compensation policy in South Carolina is rated using NCCI (National Council on Compensation Insurance) class codes. Each class code corresponds to a specific type of work and carries a base rate per $100 of payroll. Office workers (class code 8810) have a low rate because their injury risk is minimal. Roofing contractors (class codes 5551 or 5552) have high rates because falls and injuries are more common on roofing jobs.
| Industry Example | Typical NCCI Code | Risk Level |
|---|---|---|
| Office / Clerical | 8810 | Low |
| Restaurant / Food Service | 9082 / 9083 | Moderate |
| Plumbing Contractor | 5183 | Moderate-High |
| Electrical Wiring | 5190 | Moderate-High |
| Carpentry / Framing | 5403 | High |
| Roofing | 5551 | Very High |
| Trucking / Delivery | 7219 / 7228 | Moderate-High |
| Manufacturing | Varies by product | Varies |
Your class code determines your base rate, but it is not the only factor. Your experience modification rate, payroll size, state rates, and any scheduled credits or debits from the carrier also affect your final premium. The Morgano Agency reviews your class code assignments during every policy renewal to make sure employees are classified correctly. Misclassification leads to overpaying or underpaying, and both create problems at audit time.
Your experience modification rate, often called your EMR or MOD, is a multiplier that adjusts your workers comp premium based on your actual claims history compared to the average for businesses in your class code. A new business starts with a MOD of 1.0. If your claims are lower than average, your MOD drops below 1.0 and you pay less. If your claims are higher, your MOD rises above 1.0 and you pay more.
For Greenville contractors, the EMR directly affects your ability to win contracts. General contractors, property managers, and government agencies routinely require subcontractors to have an EMR below 1.0 or 1.2 as a condition of the contract. A high MOD does not just cost you in premium. It costs you in lost work.
Every workers compensation policy in South Carolina is subject to a premium audit. Your initial premium is based on estimated payroll at the start of the policy year. At the end of the policy period, the carrier audits your actual payroll records to determine the final premium. If your actual payroll was higher than estimated, you owe additional premium. If it was lower, you receive a credit.
The audit also verifies that employees are classified under the correct NCCI codes. If a clerical employee (8810) was doing warehouse work (8018), the auditor will reclassify that employee's payroll to the higher-rated code. This is why accurate job descriptions and payroll records matter.
The Morgano Agency advises Greenville clients on audit preparation, helps review audit results for accuracy, and files disputes when auditors make classification errors. Audit disputes are not uncommon, and an experienced agent can save a business thousands of dollars by catching mistakes.
In South Carolina, sole proprietors and partners are not automatically included in a workers comp policy. They can elect to include themselves, which adds their payroll to the policy and provides coverage if they are injured on the job. Many sole proprietors in Greenville choose to include themselves because their general liability carrier or a general contractor they work for requires it.
Corporate officers are automatically included in the workers comp policy in South Carolina. However, officers can file an exemption form with the SC Workers' Compensation Commission to exclude themselves. LLC members who do not perform operational work may also be excluded depending on how the business is structured.
A ghost policy is a workers compensation policy with no employees on the payroll. It exists solely to provide a certificate of insurance showing workers comp coverage. In Greenville's construction industry, general contractors require every subcontractor to carry workers comp, even if the sub is a sole proprietor with no employees. If the sub does not have coverage, the general contractor's policy picks up the exposure, which increases the GC's premium.
The Morgano Agency writes ghost policies for sole-proprietor subcontractors in Greenville. The annual premium is typically the state minimum, and it gives you the certificate of insurance you need to work on job sites across Greenville County.
The South Carolina Workers' Compensation Commission administers the state's workers comp system, including claims, hearings, and settlements. Employer obligations are defined in SC Code Title 42, which requires coverage for businesses with four or more employees. The National Council on Compensation Insurance (NCCI) sets classification codes and calculates experience modification rates used to determine premiums in South Carolina.
