Do I need workers' compensation insurance? Requirements by state

For contractors and sole proprietors, the answer depends on three things — your state, whether you have employees, and what your customer requires. Here's how to think about it, plus state-by-state guides.

The short answer: two layers

Whether you "need" workers' comp comes down to two separate questions people constantly mix up:

Why customers insist (the audit mechanic): when a GC hires you and you don't show workers' comp, their carrier charges them premium on your payments at the annual audit — so an uninsured sub literally costs them money. That's why you'll hear "no workers' comp certificate, no work," even where the state doesn't require it.

If you hire subs, this lands on you too

If you subcontract any work out, the same audit logic points at you: if your subs don't carry workers' comp, your policy gets charged for them. So collect and verify a certificate from every sub. Our free verification checklist and COI Checker help, and the COI Request Generator writes the request to send them.

Track every sub's insurance in one place

CoverProof reads each certificate, checks workers' comp and the rest against your requirements, and chases renewals automatically.
