What a certified professional employer organization is, how IRS certification differs from an ordinary PEO, what it changes for federal employment taxes, and how to check a provider’s status before you sign.
A professional employer organization enters a co-employment arrangement with your business. You keep running day-to-day work, while the PEO handles payroll, files employment taxes under its own tax ID and usually offers benefits, workers’ compensation and HR support. Because a PEO pays your employees, a natural question is who is responsible if employment taxes are not paid. For an ordinary PEO, the answer under federal law has historically been that the client business can remain liable. Certification was designed to address that uncertainty.

The Stephen Beck, Jr., Achieving a Better Life Experience Act of 2014 directed the IRS to create a voluntary certification program for PEOs, now found in sections 3511 and 7705 of the Internal Revenue Code. To be certified, a PEO applies to the IRS and must meet requirements that include background and tax compliance checks on responsible individuals, audited financial statements, a bond and ongoing reporting. The IRS publishes a list of certified PEOs and also lists organizations whose certification has been suspended or revoked. Certification is voluntary, so many legitimate PEOs are not certified.
| Topic | Ordinary PEO | CPEO, under a qualifying contract |
|---|---|---|
| Who is treated as employer for federal employment taxes on wages paid | Rules depend on the facts; client may remain liable | CPEO is generally treated as the employer |
| Liability for those federal employment taxes | Client may remain liable if the PEO does not pay | CPEO is generally solely liable |
| IRS screening | None specific to PEOs | Background, financial and bonding requirements |
| Certain tax credits | Availability depends on the arrangement | The law generally preserves certain credits for the client as if it paid the wages |
These points apply to federal employment taxes such as income tax withholding, Social Security and Medicare taxes and federal unemployment tax. State taxes, state unemployment insurance and other obligations follow state law, which varies. Confirm details in current IRS guidance or with a tax professional.
Whether or not your PEO is certified, it can only pay people correctly if you send accurate hours. For hourly employees that means daily and weekly hours worked, overtime, breaks where state law requires them, and any job or location codes your pay rules depend on. Errors in time data become errors in pay and tax filings. A clean, approved time record each period, with corrections documented, protects you and makes the PEO relationship smoother. See our employer payroll taxes glossary entry for background.
A 45-employee restaurant group compares two PEOs with similar pricing and benefits. One is on the IRS list of certified PEOs and the other is not. The owners’ accountant explains that, under a qualifying contract, the certified PEO would generally be solely liable for federal employment taxes on the wages it pays. The group chooses the CPEO, confirms the exact legal entity on the IRS list, and sets up a weekly export of approved hours so payroll runs cleanly from the first period.
EZTime is not a PEO and does not process payroll. It gives your team accurate hours to send to your PEO or payroll provider: mobile, web, kiosk and NFC clock-in, break tracking, labor rule alerts, timecard corrections with an audit trail and reports in PDF and Excel.

A PEO certified by the IRS under the voluntary program in Internal Revenue Code sections 3511 and 7705, with screening, bonding and reporting requirements.
Not necessarily for service or price. Certification mainly affects federal employment tax liability and adds IRS screening.
Under a qualifying contract, the CPEO is generally solely liable for federal employment taxes on wages it pays to worksite employees. State rules vary.
Look up the exact legal entity on the IRS public list of certified PEOs, and check the suspended and revoked list.
No. You still direct the work and remain responsible for many workplace laws, including wage and hour and safety rules.
Yes. The PEO pays based on the hours you report, so accurate time records are essential.
EZTime does not run payroll, but it exports payroll-ready reports to Excel and PDF so approved hours reach your payroll provider without retyping. Small teams pay the $20 monthly minimum; larger teams pay from $2 per employee.
