Workers' Comp Insurance
United StatesWorkers' Compensation Insurance — U.S.
Issued by State Workers' Comp Board / NCCI
Valid for 12 months (policy term)
What is Workers' Comp Insurance?
Workers' Compensation Insurance covers medical costs and lost wages for employees injured on the job. In the U.S., workers' comp is regulated state-by-state (Texas being the lone opt-out state). Premium rates are set through the National Council on Compensation Insurance (NCCI) in most states, with California, New York, and a handful of others operating their own rating bureaus. Construction classifications (like 5403 carpentry, 5645 roofing, 5022 masonry) carry some of the highest rates in the system.
Every U.S. construction company with employees needs workers' comp coverage. Most states require it at the first employee; a few allow small-employer exemptions. Sole proprietors without employees can often opt out but may still need to show proof of coverage (or a valid exemption) to work on a GC's site. Every subcontractor is expected to produce a current Certificate of Workers' Compensation when asked.
Why Expiration Tracking Matters
Workers' comp policies are annual. A lapsed policy exposes the employer to catastrophic out-of-pocket liability if a worker is injured, and most GCs block any sub without current coverage from the gate. Several states levy steep fines (per-day-per-employee) for operating without active coverage. Renewal typically involves a premium audit based on actual vs. projected payroll, which can produce surprise bills if growth wasn't reported during the year.
State & Federal Requirements
Each state sets its own rules. California and New York have their own state rating bureaus (WCIRB and NYCIRB). Ohio, Washington, Wyoming, and North Dakota operate monopolistic state funds. Texas allows opt-out (with strict substitute-employer-liability rules). Florida requires coverage at the first employee for construction. Always verify state-specific requirements before starting work in a new state.
Renewal Process
Your broker coordinates renewal 60-90 days before policy expiration. Expect a premium audit reconciling actual payroll against projections. Notify the broker of significant workforce changes mid-year to avoid large audit bills. Request the updated Certificate of Workers' Compensation immediately after renewal and distribute it to every active GC.
Common Mistakes to Avoid
- Forgetting to update coverage when adding employees in a new state — interstate work often requires per-state policies
- Missing the audit window after renewal and eating a surprise premium true-up
- Relying on a subcontractor's word rather than verifying their workers' comp certificate
- Not tracking the exemption status of 1099 contractors state-by-state

www.ncci.comFrequently Asked Questions
Most states allow sole proprietors without employees to opt out, but many GCs require either an active policy or a formal state-issued exemption on file before allowing access. Rules vary significantly by state — always check before starting work.
Most states use NCCI's classification and rating system. California, New York, Delaware, Massachusetts, Michigan, Minnesota, New Jersey, North Carolina, Pennsylvania, Texas, and Wisconsin operate their own rating bureaus with their own class codes and rates. The same construction trade can carry different rates in different states.
No. Canadian WCB coverage does not satisfy U.S. workers' comp requirements. If you're crossing the border to do construction work, you need a U.S. policy from a state-admitted carrier in the states where work happens.
