General description only; the policy that is issued, its terms, and the carrier's determination control.
What the policy actually pays
Workers' compensation pays medical costs and a portion of lost wages when an employee is injured on the job, and it is the mechanism that generally keeps that injury from becoming a lawsuit against the business. Benefit amounts are set by North Carolina statute and the Industrial Commission, not by the agency and not by a number on this page. The issued policy, the class of injury, and the Commission's rules control what is paid. This is a general description only.
The three-employee rule, and how NC actually counts
North Carolina generally requires workers' compensation once a business regularly employs three or more people, or qualifies as self-insured. Part-time and seasonal workers generally count. Corporate officers count toward the three even if they later exclude themselves from coverage; a corporation with two officers and one employee is already at the line. Sole proprietors, partners, and LLC members generally are not counted unless they elect coverage. Radiation work is a one-employee exception. If you are near three people in any working arrangement, it is worth ten minutes to find out where you stand.
Class codes and payroll: what drives the price
Every type of work has a classification with its own rate. Roofing costs more than bookkeeping because the risk is different. Premium is calculated per $100 of payroll in each class code, so the bill moves with headcount, wages, and whether people were put in the right code. The wrong code means overpaying now or a surprise at audit. We do not publish an average cost, because a roofer and an office shop are not the same risk at the same payroll. Actual premium depends on underwriting, claims history, and (once you are large enough) the experience modifier.
Sole proprietors, ghost policies, and owner exclusion
Sole proprietors with no employees generally are not required to carry comp in NC, but general contractors often require a certificate from every sub anyway; otherwise that payroll can land on the GC's audit. That is what a ghost policy is for: an owner-excluded comp policy that satisfies the certificate when there is nobody to cover. It is a compliance tool. An excluded owner who gets hurt on a job has no comp benefits at all. We will tell you plainly whether a ghost policy fits or whether you actually need owner coverage. Trade businesses that also carry GL, tools, and trucks should see the rest of the package on our contractors insurance page.
1099 labor and uninsured subcontractors
Calling someone a 1099 contractor does not decide the question. How they actually work does. If the state finds they function as employees, they count. If a sub has no workers' compensation of their own, their payroll can be picked up as yours at audit. Collect a certificate from every sub, every time, and keep it. Misclassification is one of the most common and expensive comp mistakes in the Onslow County trades.
What happens at audit
Comp premiums are estimates settled at year end. The carrier audits actual payroll and class codes, then bills or credits the difference. The surprise bills come from three places: payroll grew faster than estimated, employees drifted into higher-rated work, or uninsured subcontractors were picked up as your payroll. The fix is boring and effective: realistic estimates up front, certificates collected from every sub, and a midyear check-in when headcount changes. We build that check-in into how we service the policy. Estimating low does not reduce what you owe; it moves the bill to the audit.
Experience modifier, once you are large enough
An experience mod is a multiplier applied to premium once the business is large enough to have one. It compares your claims history to similar businesses. A mod below 1.0 reduces premium relative to the manual rate; claims push it up. New shops usually do not have one on day one.
