General Liability vs. Workers' Comp: What Illinois Contractors Actually Need

New contractors — and experienced ones bidding a new type of job — often ask the same question: "Don't I already have insurance? Why does this GC want a certificate for something else?" Here's the short version: general liability and workers' compensation cover completely different risks, and most Illinois contractors need both.

General Liability Insurance

Covers claims from people outside your business — a customer, a passerby, another trade on site. Typical claims include a client tripping over equipment, your crew damaging a client's existing structure, or a completed job later causing property damage.

Workers' Compensation Insurance

Covers your own employees if they're injured doing their job. In Illinois, this is legally required for nearly every business with employees. It covers medical treatment, lost wages during recovery, disability benefits, and death benefits for a workplace fatality.

Why Contractors Get These Confused

Both show up on a Certificate of Insurance (COI), and GCs typically require proof of both before a sub sets foot on a job site — but they insure completely different exposures.

Do 1099 Subcontractors Need Workers' Comp?

Generally, true independent contractors don't need to carry workers' comp on themselves, but many GCs will still require a certificate — either your own policy or proof of coverage under the hiring contractor's policy — to avoid liability if you're later reclassified as an employee.

The Bottom Line

If you have employees, you need both general liability and workers' comp. Metropolitan Insurance Service Consultants can review your current policies and flag any gaps before they cost you a bid.

FAQ: General Liability vs. Workers' Comp

  • Do I need both general liability and workers' comp?

    If you have employees, yes — Illinois law requires workers' comp for employees, and most GCs separately require general liability before allowing you on a job site.

  • Which one covers a client's property if my crew damages it?

    General liability. Workers' compensation only covers injuries to your own employees, not damage to a third party's property.

  • What happens if I don't carry required workers' comp coverage?

    Operating without required workers' comp coverage in Illinois can result in fines, stop-work orders, and personal liability for injury costs that would otherwise have been covered.

  • Can one policy cover both?

    No — general liability and workers' compensation are separate policy types, though Metropolitan Insurance Service Consultants can often bundle them together for convenience and savings.
