How we checked: “IRS-certified” means at least one of the company’s legal entities is on the IRS list of certified PEOs (report dated August 7, 2026). “ESAC-accredited” means the company is listed in ESAC’s Find an Accredited PEO directory. Both were checked on October 14, 2026. NAPEO membership comes from each provider’s record. Check the IRS list yourself before you sign.

Questions about PEO companies

How many PEO companies are there in the US?

NAPEO, the PEO industry’s trade association, counted 502 PEOs in the United States at the end of 2025, serving about 233,000 client businesses (PEO Industry Footprint 2026). This list covers the PEOs in the PEOIQ directory and grows as providers are added.

Which PEO companies are IRS-certified?

The ones marked “IRS-certified” above. The IRS publishes its list of certified professional employer organizations (CPEOs) and updates it every quarter. Certification belongs to a legal entity, not a brand, and one PEO can hold several, so ask which entity will sign your contract and look that name up on the IRS list.

What does ESAC accreditation mean?

ESAC (the Employer Services Assurance Corporation) is an independent nonprofit that sets financial, operational and compliance standards for PEOs and checks that accredited PEOs keep meeting them. It is different from NAPEO membership, which means a PEO joined the industry’s trade association.

Does PEOIQ rank these companies?

No. The list is alphabetical and we don’t call any PEO the best: the right one depends on your headcount, the states you hire in, your industry and the benefits you need. If you want help narrowing it down, the consultation is free. If you sign with a PEO through our broker, the PEO pays the broker, and he shares part of his fee with us.

How do I choose between PEO companies?

Start with fit: the states you hire in, your headcount, your industry and the benefits you need. Then check certification and accreditation, and compare all-in pricing quoted on the same headcount. Our guides on how to choose a PEO and the questions to ask one walk through each step.
