Do You Need Workers Comp in South Carolina? A Guide for Small Businesses and the Self-Employed

Reviewed by Vic Morgano, independent insurance agent in Greenville, SC. Updated October 31, 2026.

South Carolina generally requires workers compensation insurance when a business regularly employs four or more employees, subject to exemptions, under the South Carolina Workers’ Compensation Act (Title 42 of the SC Code of Laws) enforced by the SC Workers’ Compensation Commission. Businesses with fewer than four employees, along with some sole proprietors and independent contractors, can be exempt depending on structure and the type of work performed. The Morgano Agency, an independent insurance agency in Greenville, SC, helps Upstate business owners figure out exactly where they land on that four-employee line before it turns into a compliance problem.

Nobody Googles workers comp rules for fun. You’re here because something changed. You hired your first employee. Or a general contractor won’t let you on the job site without proof of coverage. Or you work for yourself and you’re not sure the rules even apply to you. The question underneath all of it is simple: does South Carolina require workers compensation insurance for a business like yours? SC workers comp rules can turn on employee count, business structure, and the kind of work being performed. Sometimes the answer is yes. Sometimes you’re completely off the hook. It comes down to how many people work for you and what kind of work you do. If you do need coverage, you can skip ahead to a commercial quote or start at the broader business insurance hub.

The rest of this page is for the people who usually get the murkiest answers: the self-employed and small businesses with a handful of workers. We start with the rule that decides almost everything, the four-employee threshold, then get into workers compensation for the situations the state does not spell out clearly.

What Are South Carolina’s Workers Compensation Requirements for Employers?

As a general rule under the South Carolina Workers’ Compensation Act (Title 42 of the SC Code of Laws), businesses that regularly employ four or more employees in South Carolina must carry workers compensation insurance, subject to exemptions. This is enforced by the South Carolina Workers’ Compensation Commission.

Here is what counts toward that four-employee threshold:

• Part-time employees count. South Carolina counts part-time workers toward the four-employee threshold. Two full-time employees and two part-time employees equals four.
• Family members count. If your spouse or children work in the business, they are counted as employees under SC workers comp law.
• Seasonal and temporary workers may count. Whether the business regularly employs the required number depends on its circumstances.

Figures current as of July 2026. Whether a general contractor or a subcontractor with fewer than 4 employees must separately carry coverage is decided case by case by the SC Workers’ Compensation Commission, not by a flat rule.

Do Sole Proprietors and the Self-Employed Need Workers Comp in SC?

If it is just you and nobody on payroll, South Carolina does not require you to carry workers compensation insurance. A sole proprietor, a single-member LLC, a freelancer, an independent contractor working solo, none of them are forced into a policy by the state. The four-employee rule simply has not reached you yet.

That is the legal answer. The practical answer is where it gets interesting. Plenty of self-employed people in Greenville carry workers comp even though nobody made them. The reason is usually a general contractor who won’t let them onto a commercial site without a certificate of insurance proving coverage. A regular health plan generally won’t pay for an injury that happened on the job either, which leaves a solo worker exposed. Get hurt swinging a hammer with no employees and no policy, and every dollar of that bill is yours.

Owner coverage and elections depend on business structure and policy terms. Ask your insurer or the Commission whether an owner may be included and what the coverage would cost.

Workers Compensation for Greenville Businesses by Industry

The general four-employee rule applies across industries, subject to exemptions. Certain industries in the Greenville area may have distinct workplace risks:

Workers Comp Exemptions in South Carolina

South Carolina exempts certain categories of workers from the workers compensation requirement:

• Employers with fewer than four employees (statutory-employer responsibilities for subcontractors can be fact-specific)
• Employers with total annual payroll under $3,000 in the previous calendar year
• Casual employees not in the employer’s usual course of business
• Agricultural workers
• Federal government employees (covered by federal workers comp programs)
• Railroad workers (covered by the Federal Employers Liability Act)
• Licensed real estate agents paid solely by commission

Owner elections and exclusions depend on business structure; confirm with your insurer or the Commission.

SC Workers Comp Penalties: What Happens Without Coverage

The exclusive remedy protection is one of the most important reasons to carry workers comp even if you are just at the threshold. Under workers comp, an injured employee receives benefits (medical expenses, lost wages, disability) but generally cannot sue the employer in civil court. Without workers comp, that protection disappears, and a serious injury can become a business-threatening expense.

NCCI Class Codes and Workers Comp Premium Calculation in SC

Workers compensation premiums in South Carolina are based on three factors:

1. NCCI class code. The National Council on Compensation Insurance (NCCI) assigns a classification code to every type of work. Office workers have a different class code (and much lower rate) than roofers. Each code has a base rate per $100 of payroll.
2. Payroll. Your premium is calculated per $100 of payroll for each class code. More employees and higher wages mean higher premiums. This is why construction companies pay more than accounting firms.
3. Experience modification rate (EMR). Your EMR is a multiplier based on your company’s claims history compared to similar businesses. A clean claims history gives you an EMR below 1.0, which lowers your premium. Multiple claims push it above 1.0. A high EMR can make it difficult to bid on commercial contracts because many general contractors require subs to have an EMR under 1.0.

An independent insurance agent can help you make sure your employees are classified under the correct NCCI codes. Incorrect classification is one of the most common reasons businesses overpay for workers compensation insurance. A restaurant owner whose servers are classified under the kitchen staff code pays more than necessary. An agent who understands the classification system catches these errors.

Subcontractor Workers Comp Liability in South Carolina

This is where workers comp in South Carolina gets complicated for Greenville business owners, especially in construction.

General contractor liability

Under SC law, a general contractor may have workers compensation responsibility for employees of a subcontractor, depending on statutory conditions and the facts. Review contracts, the parties’ coverage and applicable law; do not assume that every injury will be paid by the general contractor’s policy.

This is why general contractors in Greenville require certificates of insurance (COIs) from every subcontractor before they step on a job site. If you are a sub, not having workers comp limits the GCs you can work with.

Independent contractors (1099 workers)

Classifying workers as independent contractors (1099) does not automatically exempt you from workers comp. The SC Workers’ Compensation Commission looks at the actual working relationship, not just the tax classification. If you control when, where, and how someone does their work, they may be classified as an employee regardless of how you pay them.

If you rely on 1099 workers, have your insurance agent review the relationship so you do not accidentally create a workers comp exposure.

What Greenville Employers Need To Do After a Workplace Injury

When an employee gets hurt, the employer process matters first. Report the injury internally right away, get the worker appropriate medical attention, and document what happened while the details are still fresh.

Promptly report a workplace injury to your insurer or claims administrator and confirm the applicable Commission reporting obligations and deadlines. Form 12A is the first report of injury. Quick reporting helps the claim move cleanly and reduces avoidable delays, disputes, and paperwork problems.

If your business has trouble finding coverage in the standard market, the state’s assigned risk program may be the fallback. Your policy still needs the right class code, payroll estimate, and claims handling process in place before an injury happens.

For Greenville business owners, workers comp is about more than checking a compliance box. It protects cash flow, keeps jobs moving, and helps you stay eligible for contracts that require proof of coverage.
