Workers' Comp FAQ

Yes. South Carolina law (SC Code § 42-1-360) requires any employer with four or more employees to carry workers' compensation insurance. Part-time, seasonal, and temporary employees count toward that number. Certain agricultural workers and domestic servants are exempt. Sole proprietors and partners are automatically excluded but may elect to be covered. The penalty for operating without required coverage includes fines, stop-work orders, and personal liability for any claims that occur.

Workers' comp covers two main areas. First, medical benefits — all reasonable and necessary medical treatment for a work-related injury or illness, with no deductible or copay for the employee. Second, indemnity benefits — wage replacement if the employee misses more than seven days of work due to the injury (66⅔% of the employee's average weekly wage, up to the SC maximum). It also covers permanent disability benefits if the injury results in lasting impairment, vocational rehabilitation if the employee can't return to their prior job, and death benefits for surviving dependents.

Workers' comp does not cover injuries that are self-inflicted, caused by the employee being intoxicated or under the influence of drugs, or that occur while the employee is commuting to or from work (the “going and coming” rule). It also does not cover injuries that occur while an employee is violating a known safety rule, engaged in horseplay, or committing a crime. Independent contractors (1099 workers) are generally not covered unless misclassified or your state rules require their inclusion.

Not automatically — but this is one of the most misunderstood areas of workers' comp. In South Carolina, if a worker is a legitimate independent contractor with their own business, their own tools, and control over how they perform their work, they are not your employee and are not covered under your policy. However, if the carrier or a court determines the worker was misclassified, or if the contractor cannot provide a certificate of insurance showing their own coverage, their payments can be added to your auditable payroll at audit. When in doubt, require every contractor to show a current COI before they start work.

Four. SC uses the “Rule of Four” — if you have four or more employees at any point during the policy year, you are required to carry coverage. This includes part-time, seasonal, and temporary workers. Even if your employee count fluctuates, if you hit four at any time, you need a policy in place. Sole proprietors and LLC members are typically excluded by default from the count but may opt in.

The basic formula is: (Payroll ÷ 100) × Class Code Rate × Experience Mod × Schedule Credit/Debit = Manual Premium. The class code rate is set by NCCI and approved by the SC DOI — it represents the expected cost per $100 of payroll for that type of work. The experience mod adjusts that based on your actual claims history. And the schedule credit or debit is your underwriter's subjective adjustment based on factors like your safety program, management quality, and financial stability. The final number is your deposit premium — subject to audit at year end.

Your experience mod is a multiplier applied to your base premium based on how your actual claims history compares to what's expected for an employer of your size and industry. An experience mod of 1.0 means your losses are exactly average. A mod of 0.85 means you're paying 15% less than the base rate — you've had fewer or smaller claims than expected. A mod of 1.25 means you're paying 25% more. In South Carolina, your mod is calculated by NCCI using up to three prior policy years of data. A single large indemnity claim can drive your mod up significantly for three years.

Several things can cause a premium increase at renewal with no claims. NCCI periodically adjusts the base rates for class codes in SC — if your code's rate went up, your premium goes up. Your experience mod could have changed based on prior years' data rolling in or out of the calculation window. Your payroll may have grown. Or your carrier may have applied a less favorable schedule credit than the prior year. Ask your agent to provide a side-by-side comparison of the rating factors year over year so you can see exactly what changed.

A schedule credit or debit is a carrier underwriter's discretionary adjustment to your manual premium — typically ranging from -25% to +25%. Carriers use this to reflect factors not captured by class codes or the experience mod, such as your safety program quality, management experience, financial strength, loss control practices, and workplace culture. A strong safety record and documented safety program can help you negotiate a better schedule credit. It is not standardized — two carriers may apply very different adjustments for the same risk.

Generally, you cannot externally finance a workers' comp policy the way you might finance a commercial auto or general liability policy. Most premium finance companies will not finance workers' comp because the policy is subject to audit and the final premium is unknown at inception. However, most carriers provide built-in installment options — typically monthly or quarterly payments — often with a modest installment fee. If upfront cash is a concern, ask your agent specifically about installment plans at binding. Pay-as-you-go programs (see below) are another effective solution for cash flow management.

Pay As You Go is a workers' comp payment structure where your premium is calculated and billed each payroll cycle based on your actual wages paid that period — rather than estimating your full annual payroll upfront and paying a large deposit. Instead of guessing what your payroll will be for the year, you report actual payroll to the carrier (often integrated directly with your payroll provider) and pay the corresponding premium at each cycle. The benefits are significant: no large upfront deposit, no surprise audit bill at year end (because you've already been paying on actual payroll), and better cash flow alignment. It is particularly valuable for businesses with seasonal or variable payrolls.

No. Most carriers offer installment billing — typically a down payment (often 25–33% of estimated annual premium) at policy inception, with the balance paid monthly or quarterly. Some carriers charge a small installment fee for this convenience. If you're enrolled in a Pay As You Go program, there may be little to no upfront deposit at all. Ask your agent to show you the installment options before you bind coverage.

If you miss a payment, the carrier will typically send a notice of cancellation after a short grace period (usually 10–30 days). If the policy cancels for non-payment, you are uninsured — and any injury that occurs during a lapse in coverage is your personal financial liability. In South Carolina, operating without required WC coverage also exposes you to regulatory penalties and stop-work orders. If you're struggling with premium, contact your carrier before missing a payment — many will work out a payment arrangement. Lapsing the policy is almost always the worse outcome.

Yes, but there are financial consequences. Most policies have a “short rate” cancellation penalty if you cancel before the policy anniversary — meaning you receive less than a pro-rata refund of unearned premium. The policy also goes to audit at cancellation, and you may owe additional premium if your payroll ran ahead of estimates. If you're canceling to switch carriers, make sure the new policy is fully bound before canceling the old one — even a single day without coverage creates risk.

Get the employee medical attention first — that is always the priority. In South Carolina, you as the employer have the right to direct medical care under WC, which means you choose the authorized treating physician (unless it is a life-threatening emergency). After care is arranged, document the incident thoroughly: written incident report, witness statements, photos of the scene if applicable. Report the claim to your carrier promptly — most policies require notice “as soon as practicable,” and delays in reporting can complicate the claim. Notify your HR team and keep records of all communications.

Workers' comp claims affect your experience modification factor, which directly impacts your premium at renewal. The impact depends on the type and size of the claim. Indemnity claims (those involving lost wages) carry more weight in the mod calculation than medical-only claims. Large claims hurt more than small ones, but NCCI's formula caps any single claim's impact to some degree. A single significant indemnity claim can raise your experience mod for three policy years. This is why return-to-work programs, prompt reporting, and proactive claim management are so important — getting an injured employee back to work quickly reduces indemnity costs and limits the mod impact.

In most cases, workers' comp is the exclusive remedy — meaning an injured employee cannot sue you in civil court for a workplace injury if you have a valid WC policy in place. This is the fundamental “grand bargain” of workers' comp: employees give up the right to sue in exchange for guaranteed benefits regardless of fault. However, there are limited exceptions: if you intentionally cause harm, in certain cases involving dual capacity, or in states that allow certain types of third-party actions. Employer's Liability (Part B of your WC policy) provides coverage for these edge cases.

A medical-only claim involves just medical costs — no lost wages because the employee was able to return to work within the waiting period (in SC, the first seven days of lost time are not compensable). Medical-only claims are discounted in the experience mod calculation — they carry only about 30% of the weight of an indemnity claim. An indemnity claim involves both medical costs and wage replacement payments. These claims are weighted fully in the mod calculation and have a larger and longer-lasting impact on your premium.

It depends on your business structure. In South Carolina: Sole proprietors and general partners are automatically excluded but may elect to be covered. Corporate officers (C-Corp, S-Corp) are included by default but may exclude up to two officers by filing the proper exclusion form with the carrier in writing. LLC members are generally treated like corporate officers. Ghost policies are common for sole proprietors in construction — they purchase a policy with themselves excluded, producing a COI that satisfies general contractor requirements without providing actual coverage. If you want an exclusion, it must be formally documented with the carrier — verbal agreements don't count and will not hold up at audit.

A ghost policy is a workers' compensation policy in which the only insured is an owner who has excluded themselves from coverage. The policy technically exists and produces a valid certificate of insurance — which many general contractors require before allowing a sub to work — but it provides zero actual coverage because the only person on the policy is excluded. Ghost policies are legal in South Carolina and widely used by sole proprietor subcontractors in construction. The premium is typically very low (often a few hundred dollars per year) because there is no payroll and no actual coverage. The risk is that if someone is injured on the job, there is no WC coverage to respond.

Loss runs are a report from your current or prior insurance carrier showing your workers' comp claims history — claim dates, types of injuries, amounts paid, and amounts reserved for future payments. When you apply for WC coverage, virtually every carrier will ask for three to five years of loss runs. Good loss history (few claims, closed claims with low total cost) puts you in a strong negotiating position. Poor loss history may limit your carrier options or result in higher rates. You have the right to request loss runs from your current carrier at any time — they are required to provide them within a reasonable timeframe.

Yes, but it requires canceling your current policy and going through a short-rate penalty, and the old policy will still go to final audit. Practically speaking, most employers switch at renewal rather than mid-term. If you're switching mid-term because of a rate dispute or service issue, make sure the new policy is bound before you cancel the old one, verify your experience mod carries over correctly, and confirm the audit with the old carrier is properly handled. Your agent should coordinate this transition.

For most standard risks, a workers' comp policy can be bound in 24–48 hours once the application is completed and underwriting approves it. More complex risks — high-hazard industries, poor loss history, very large payrolls — may take several days to a week for the carrier to review and price. In urgent situations (you have a job starting tomorrow that requires a certificate), most carriers can accommodate same-day or next-day binding for straightforward risks. Having your loss runs, payroll by class code, and FEIN ready will speed up the process significantly.

South Carolina's workers' compensation law (SC Code § 42-1-360) requires coverage when an employer has four or more employees. Unlike some states that count only full-time workers, South Carolina counts all employees — full-time, part-time, seasonal, and temporary — toward the threshold. If you hit four employees at any point during the year, you need a WC policy. Subcontractors are not counted unless they lack their own coverage (in which case, they may be treated as your employees for WC purposes).

The consequences in South Carolina are serious. Without required WC coverage, you are personally liable for the full cost of the employee's medical treatment and lost wages — with no cap. The SC Workers' Compensation Commission can issue a stop-work order forcing you to shut down operations until coverage is obtained. You can be fined up to $100 per day for each day you operated without required coverage. The injured employee can also sue you directly in civil court, which may result in damages significantly beyond what WC would have paid. There is no scenario where going without required coverage is the financially rational choice.

Workers' comp in South Carolina is regulated jointly by the South Carolina Department of Insurance (SC DOI) — which regulates carriers, rates, and policy forms — and the South Carolina Workers' Compensation Commission (SCWCC) — which oversees claims, disputes, and settlements between employers, employees, and carriers. NCCI (the National Council on Compensation Insurance) sets the class codes and statistical rules. If you have a dispute with your carrier over a policy or audit matter, the SC DOI is your regulator. If you have a dispute over a claim, the SCWCC is the adjudicating body.

No — not initially. In South Carolina, the employer has the right to direct medical care, meaning you or your carrier selects the authorized treating physician. The employee must treat with the authorized physician for their care to be compensated under WC. If the employee chooses to see their own doctor without authorization, those costs are generally not covered. There are exceptions for emergency care and, in some cases, the employee may request a change of physician through the SCWCC. This is an important and often misunderstood aspect of SC WC law — make sure injured employees understand the process immediately after an injury.
