Workers compensation insurance in South Carolina: what the law actually requires
If you own a business in South Carolina and have employees on payroll, workers compensation insurance is almost certainly a legal requirement, not an optional benefit. Many small business owners assume the threshold is higher than it is, or that certain types of workers don't count. Those assumptions can lead to fines, lawsuits, and out-of-pocket medical bills that could sink an otherwise healthy business. This post breaks down the state rules, the real costs, and how to make sure you're covered correctly.
Who must carry workers comp in South Carolina
South Carolina law (S.C. Code Ann. Section 42-1-150) requires most private employers to carry workers compensation coverage once they have four or more employees , whether those employees are full-time, part-time, or seasonal. That four-person count includes owners and officers of the company in most cases.
A few categories are exempt or treated differently:
- Agricultural employers: farm operations with fewer than ten workers performing seasonal hand-harvest labor are generally exempt, though other agricultural workers may still be covered.
- Domestic service workers: household employees (cleaners, nannies, etc.) hired by private individuals fall outside the mandate, though voluntary coverage is still an option.
- Sole proprietors and partners: they are not automatically covered but can elect to include themselves on a policy.
- Corporate officers: officers of a corporation are counted as employees for the four-person threshold and are covered unless they formally opt out in writing.
- Certain casual laborers: one-time or truly incidental workers whose duties are unrelated to the business's trade may not count, but this is a narrow exception and often misapplied.
The safest position: if someone works for you regularly and you direct their work, assume they count toward the threshold. Misclassifying a worker as an independent contractor when the state or a court views them as an employee is one of the most common and expensive mistakes employers make.
What workers comp actually covers
Workers compensation is a no-fault system. An injured employee does not have to prove negligence to collect benefits, and in exchange, they give up the right to sue the employer for most work-related injuries. A standard policy covers:
- Medical expenses: all reasonable and necessary treatment for a work-related injury or illness, including emergency care, surgery, physical therapy, and prescription drugs.
- Lost wages (temporary total disability): if an injured worker cannot do any work, South Carolina pays 66.67% of the worker's average weekly wage , subject to a maximum set by the SC Workers' Compensation Commission each year (the 2024 maximum is $1,035.78 per week).
- Temporary partial disability: if the worker can return on light duty at reduced pay, a portion of the wage difference is covered.
- Permanent disability: benefits based on the severity of the permanent impairment, rated by body part under SC's scheduled loss chart.
- Vocational rehabilitation: job retraining when the worker cannot return to their prior occupation.
- Death benefits: dependents of a worker killed on the job receive a weekly benefit (same 66.67% formula) for up to 500 weeks, plus up to $2,500 toward burial costs.
Employers' liability coverage, typically packaged with the workers comp policy as "Part Two," applies if an employee sues the employer outside the workers comp system, such as a claim that the employer intentionally caused harm.
What it costs and what drives the premium
Workers compensation premiums in South Carolina are calculated using a standard formula: payroll (per $100) x class code rate x experience modifier . There is no flat fee. What you pay depends heavily on your industry and your claims history.
Class codes are assigned by the National Council on Compensation Insurance (NCCI) and reflect the relative risk of different job types. A few examples relevant to the Myrtle Beach and Grand Strand area:
- Restaurants (code 9082): typically between $1.50 and $3.00 per $100 of payroll in SC, depending on the carrier and experience mod.
- Retail stores (code 8017 or 8018): often in the $0.75 to $1.50 range.
- Roofing contractors (code 5551): among the highest in the state, sometimes $15 to $25 per $100 of payroll, which is why roofers sometimes operate without coverage (a costly gamble).
- Clerical staff (code 8810): very low risk, often under $0.25 per $100 of payroll.
The experience modification factor (experience mod or "e-mod") is a multiplier applied after three years of claims history. A 1.0 is average. A 0.85 means you've had fewer-than-average claims and pay 15% less. A 1.25 means your claims have been above average and you pay 25% more. Keeping that number below 1.0 is one of the most direct ways small businesses control their premium year over year.
South Carolina also participates in the NCCI's assigned risk plan (the SC Assigned Risk Pool) for employers who cannot find coverage in the voluntary market, usually because of a poor loss history. Rates in the assigned risk pool are higher, so maintaining a clean record keeps more carriers willing to compete for your business.
Penalties for non-compliance in South Carolina
Operating without required workers comp coverage in South Carolina is not a technicality. The penalties are real:
- Civil fines: the SC Workers' Compensation Commission can assess fines up to $100 per employee per day of non-compliance. A small crew of six employees uninsured for 30 days adds up to $18,000 in fines alone.
- Stop-work orders: the Commission has authority to shut down a business until coverage is obtained and fines are paid.
- Personal liability: if an uninsured employer is found liable for a worker's injury, the employer pays all medical costs, lost wages, and potential damages directly out of pocket. A single serious back injury can easily exceed $100,000.
- Criminal exposure: willful failure to maintain coverage can rise to a criminal misdemeanor under SC law.
The Commission does conduct audits, and complaints from workers or competitors trigger investigations. Non-compliance rarely goes unnoticed for long, especially in higher-visibility industries like construction, where subcontractors are regularly asked to provide certificates of insurance.
Special situations South Carolina employers often overlook
Subcontractors and independent contractors
If you hire an uninsured subcontractor and a court determines that worker is actually an employee, you are on the hook for any injury. General contractors in South Carolina routinely require subcontractors to provide a certificate of insurance showing their own workers comp coverage. If the subcontractor doesn't have it, the general contractor's policy may cover them, and the general contractor gets charged for it at audit. Always collect certificates before work begins.
Seasonal tourism businesses
The Grand Strand economy runs on hospitality, retail, and outdoor recreation, all of which spike from April through September. When you add seasonal staff, your payroll estimate changes and your premium adjusts at audit. Underestimating seasonal payroll at the start of the policy year means a larger-than-expected audit bill at the end. Build honest seasonal projections into your application to avoid that surprise.
Remote employees working in South Carolina
If your business is headquartered outside South Carolina but you have even one employee regularly working from home in the state, South Carolina workers comp requirements may apply to that worker. Multi-state coverage endorsements handle this, but you need to confirm your policy actually lists SC.
Executive officers electing out
SC allows corporate officers to formally exclude themselves from coverage, which reduces the payroll base and lowers the premium. An officer who opts out has no workers comp protection if injured. This is a trade-off worth thinking through carefully, particularly for working owners in physically demanding roles.
How to get the right coverage for your business
Workers comp is one of those lines where shopping multiple carriers genuinely matters. Rates, class code interpretations, and audit procedures vary more across carriers than most business owners realize. Working with an independent commercial insurance agent means someone is comparing options from multiple insurers on your behalf rather than steering you toward a single company's product.
Come to that conversation with a few things ready:
- Total annual payroll by job type: accurate payroll figures by employee classification make the quote accurate and reduce audit surprises.
- Loss runs for the past three to five years: if you've had prior coverage, your claims history follows you. Loss runs let carriers see your actual experience, not just your e-mod.
- Description of operations: what your employees actually do day-to-day, not just your general industry category. A restaurant with delivery drivers has different exposure than one without.
- Safety programs in place: documented safety training, return-to-work programs, and drug testing can influence both the carrier's willingness to write your policy and the premium they charge.
Pairing workers comp with a broader business policy also makes sense for most small businesses. A Business Owner's Policy (BOP) bundles general liability and commercial property into one cost-effective package, and understanding how those pieces fit together helps you spot gaps before something happens, not after.
