South Carolina Workers' Comp Requirements: The 4-Employee Rule and Its Exceptions

If you hire people to work in South Carolina, workers' compensation coverage is often mandatory, and the rule is simpler than many owners expect. The real questions are how many people you regularly employ, how you pay them, and whether an exemption fits your business. This guide explains how South Carolina applies the four-employee threshold, which workers are exempt, and which filings the South Carolina Workers' Compensation Commission (WCC) expects from employers.

This article is informational, not legal or tax advice. Workers' comp rules turn on specific facts. Confirm your situation with the WCC, an attorney, or a qualified insurance agent before you rely on it.

The four-employee rule

South Carolina requires workers' compensation coverage for a business that regularly employs four or more people in the state. The count is broader than full-time payroll. Part-time workers count, and so do family members who work in the business. A shop with two full-time employees, one part-time counter worker, and a family member on the payroll has four employees for this purpose.

The word "regularly" matters. Count the people you employ on an ongoing basis, not the peak number you reach once during a busy season. If your headcount is hovering at three or four, check the rule before you hire the next person, not after an injury happens.

Because the count is ongoing, the obligation can start the day your headcount crosses the threshold. Build a coverage check into your hiring process so that the policy is in place before the new employee starts work.

Who is exempt

The four-employee threshold is not the only test. South Carolina law exempts several categories of workers and businesses. The following are generally exempt, but each has conditions, and a worker's status depends on the facts of the job, not the job title:

• Casual employees, meaning workers hired for occasional, incidental work rather than ongoing employment. Whether a role is truly casual is a judgment call, so confirm it with the WCC before you depend on it.
• Businesses with fewer than four employees, or with an annual payroll under $3,000.
• Agricultural employees.
• State and county fair associations.
• Railroads.
• Federal employees, who fall under federal compensation programs instead of the state system.
• Owner-operator drivers, who run their own trucks or equipment and are not employees for this purpose.
• Certain commission-paid real estate agents.

If you think one of these exemptions covers you, get the answer in writing from the WCC or your attorney. Owners who guess at an exemption and turn out to be wrong often learn about it only after a worker is hurt.

Paying workers on a 1099 does not avoid coverage

Workers' comp follows the actual working relationship. A 1099 form does not make someone a contractor. If you pay a person on a 1099 but set their hours, supply their tools, direct how the work gets done, and can fire them at will, that person may be treated as an employee and counted toward your total.

Review the relationship, not the paperwork. Ask who controls the schedule, who provides the equipment, whether the worker serves other clients, and whether the work is part of your regular operations. A genuine independent contractor usually answers those questions very differently from a person who works for you like any other staff member. Misclassification also creates tax exposure, so a CPA should review any worker you are unsure about.

Subcontractors and statutory employer liability

This is where many contractors get hurt. Under South Carolina law, a general contractor can be treated as the statutory employer of a subcontractor's workers. If the subcontractor has no workers' compensation coverage and one of its workers is injured on your project, the general contractor may be responsible for the benefits.

That is why general contractors demand a certificate of insurance before a subcontractor begins work. Treat the certificate as the start of the check, not the end of it:

• Collect a certificate from every subcontractor before work starts, and keep copies in the project file.
• Confirm the policy is active on the dates the work will happen, not just on the date the certificate was issued.
• Check that the coverage matches the work. A certificate for a different trade or location may not protect you.
• If a subcontractor cannot produce a certificate, do not let its crew start on site until the coverage question is resolved.

Subcontractor agreements should also require the sub to keep coverage in place for the full project and to notify you if the policy lapses.

Sole proprietors, partners, and corporate officers

Owners are treated differently from employees, and the rules here are more flexible.

• Sole proprietors and partners are not automatically covered by a workers' comp policy, but they may elect to be covered. Electing in can protect the owner who is injured on the job, and it is worth weighing against the premium cost for a one-person operation.
• Corporate officers may reject coverage for themselves. An officer who opts out is not counted in the same way as a regular employee, but the decision has real consequences if that officer is injured. Document the decision and keep it with your corporate records.

An owner who elects in or withdraws should confirm the change with the WCC and with the insurance carrier. Coverage that is not properly elected or rejected can leave a gap that surfaces only after an injury.

WCC filings and Form 38

The South Carolina Workers' Compensation Commission handles the state's workers' comp filings and rules. The filing you are most likely to need as an owner is Form 38, the form used to elect into coverage or to withdraw from it. Sole proprietors, partners, and corporate officers use the election process described above, so check Form 38 whenever your ownership or coverage status changes.

Other WCC filings, including reports of work-related injuries, have their own forms and deadlines. Do not rely on a deadline from another state or from an old checklist. Download the current forms from the WCC and confirm the filing rules with the agency directly.

How to check your status

Work through these steps in order before you hire, or whenever your headcount changes:

1. Count everyone on the payroll regularly, including part-time workers and family members.
2. Classify each worker by the actual relationship, looking at control, tools, and independence rather than the form used to pay them.
3. Test each exemption against your facts. Do not assume an exemption applies because the business is small or the work is informal.
4. Get coverage or written confirmation. If you are at or near four employees, or an exemption is borderline, buy the policy or get the exemption confirmed in writing before the question becomes urgent.
5. Collect certificates from every subcontractor and verify that the coverage is active for the project dates.
6. Calendar your WCC filings, including any Form 38 election or withdrawal, and review them whenever ownership changes.

Common situations and what to check

Situation	What to check
Four people on the payroll, three full-time and one part-time	Part-time workers count toward the total. Coverage is generally required, so confirm with the WCC if you believe an exemption applies.
Two employees plus one 1099 worker who keeps set hours and uses your tools	The 1099 label does not control. The worker may be an employee and counted toward the threshold.
Hiring a subcontractor that cannot show a certificate	As a general contractor, you may be responsible for an injured sub worker if the sub lacks coverage. Hold off on starting the sub's crew.
Sole owner who wants no coverage for herself or himself	Sole proprietors may elect coverage. Confirm the choice and the filing with the WCC and your carrier.
Corporate officer who wants to opt out	Officers may reject coverage. Document the decision and keep it with corporate records.

Where to get help

Start with the South Carolina Workers' Compensation Commission for rules, forms, and filing questions. For exemption questions, ask the WCC in writing so you have a record of the answer.

Your insurance agent can explain how the policy handles your payroll, your subcontractors, and any owner elections. A workers' comp carrier can also tell you how your classification codes affect your premium.

If you are building a business plan around a small team or a subcontractor model, the South Carolina Small Business Development Centers offer advising that can help you think through the structure before you commit to hires. For disputes, lapsed coverage, or a claim that is already open, talk to an attorney who handles South Carolina workers' compensation. For tax consequences of worker classification, consult a CPA.
