PEO Workers' Comp on a Subcontractor's COI: What It Covers and What to Check

By SubCover HQ · Updated Nov 2, 2026 · 3 min read

More small contractors now run payroll through a professional employer organization (PEO) or employee leasing company. The PEO becomes the co-employer and often provides workers' comp through its own master policy. When you ask that sub for a certificate, you may get one that lists the PEO, not the sub, as the insured, or lists both. Here's how to tell whether it actually covers the people on your job.

How PEO workers' comp works

The PEO buys a workers' comp policy covering employees on its payroll at its client companies. Your sub is one of those clients. Coverage usually extends to the sub's workers only while they're on the PEO's payroll, and the policy often uses an alternate employer endorsement (commonly ISO/NCCI form WC 00 03 01) to name the client company so it's protected as the employer too.

What to check on the certificate

  1. Your sub is named. The certificate should name your sub, for example in the insured field, the description box, or an attached client schedule, as a covered client or alternate employer. A certificate that names only the PEO, with no link to your sub, doesn't show your sub's crew is covered.
  2. The coverage is current. PEO relationships end. Check the policy dates, and ask the PEO to confirm the client relationship is active.
  3. The state matches. Confirm the policy covers work in the state where your job is.
  4. Employers' liability limits meet your contract.
  5. Waiver of subrogation in your favor, if you require it. PEO master policies can often add it, but ask.

The gaps to watch for

A simple request to send

Ask the sub to have the PEO issue a certificate that shows your sub as a covered client or alternate employer, the policy dates, the states covered, employers' liability limits, and any waiver of subrogation you require. Our free COI email templates include a request you can adapt.

Track both sources

A PEO sub means two sets of documents: the PEO's workers' comp certificate and the sub's own GL and auto certificate, often with different dates. SubCover HQ collects both, checks each against your requirements, and chases renewals with the right party, for $99/month.

Frequently asked questions

What is a PEO?

A professional employer organization co-employs a company's workers and handles payroll, benefits, and often workers' comp under its own policy.

Does a PEO certificate cover my subcontractor's whole crew?

Only workers on the PEO's payroll. Helpers paid on 1099s or others outside the PEO payroll may not be covered, so ask.

What is an alternate employer endorsement?

An endorsement, commonly NCCI form WC 00 03 01, that extends workers' comp protection to a named client company that co-employs the PEO's workers.

Does the PEO provide general liability too?

Usually not. You still need the sub's own general liability and auto certificate from its insurance agent.
