CPEO certification: what it actually covers

A Certified Professional Employer Organisation is an entity that has satisfied the Internal Revenue Service certification programme establishing that the PEO, not the client, is solely liable for federal employment taxes on wages it pays. The IRS publishes the roster of active CPEOs and posts suspension notices when a certification lapses.\n\nCertification differs from accreditation. A CPEO passes IRS financial, background, and reporting requirements; an accredited PEO passes ESAC's industry standards. Some PEOs hold both. See what co-employment means in practice for the underlying legal doctrine, ESAC for the accreditation regime, and per-head monthly pricing for the pricing model many CPEOs quote in. A prospective client verifying CPEO status can pull the roster directly from the IRS site without vendor cooperation, which makes it one of the cheaper independent checks available at contract stage. The help hub collects further reading, and the PEO regulatory hub publishes state-level regulatory detail.\n\n## What this doesn't cover\n\nCPEO status speaks to federal-tax indemnification only; state unemployment, workers' compensation, and benefits liability are separately governed by state statute and the PEO service agreement.
