Professional Employer Organization

How a PEO works

You sign a client service agreement with the PEO. Your employees become worksite employees of the PEO for specific purposes, and you remain their employer for everything else. This shared arrangement is called co-employment.

In a typical setup the PEO:

• Runs payroll and, in most arrangements, reports wages and remits payroll taxes under its own tax ID
• Sponsors health, dental, vision and retirement plans that your employees join
• Carries or arranges workers' compensation coverage
• Provides HR policies, an employee handbook, compliance help and often an HR platform
• Handles unemployment claims and some state registrations

You keep control of who you hire and fire, what people do, how much you pay them, and the culture of your workplace. You must already have a legal business entity. A PEO does not let you employ people in a place where you have no entity; that is what an employer of record does.

PEO benefits for employers

The biggest draw is benefits. A 40-person company buying health insurance alone has little negotiating power and limited plan choice. Pooled into a PEO's large group, the same company can often offer plans that look like those of a much larger employer. Sometimes premiums are lower; more often, plan options and stability are better. Check the actual quotes rather than assuming savings.

Other practical benefits:

• Admin time back. One person is no longer running payroll, chasing benefits enrollment and answering leave questions alone.
• Compliance support. Help with state registrations, required notices, harassment training and multi-state payroll when you hire remote staff.
• Workers' comp. Pay-as-you-go premiums based on actual payroll instead of an annual estimate and audit.
• HR expertise on call. Useful for a company with no dedicated HR person or a single generalist.

This is why PEOs are most common in companies with roughly 10 to 150 employees. Past a few hundred employees, most organizations build in-house HR and buy employee benefits directly.

What a PEO costs

There are two common pricing models:

• Per employee per month (PEPM): commonly around $100 to $200 per employee per month for full-service PEOs, before benefit premiums.
• Percentage of payroll: often 2% to 12% of gross payroll, which may bundle in workers' comp and other costs.

Worked example: a 35-person dental group with $2.1 million in annual payroll gets a PEPM quote of $145. That is 35 × $145 × 12 = $60,900 a year in admin fees. The practice manager estimates the PEO saves her 20 hours a month of payroll and benefits work and replaces a $9,000 payroll software contract and an outside HR consultant billing about $15,000 a year. Whether $60,900 is worth it depends mostly on the benefits quote: if the PEO plan saves $1,000 per enrolled employee per year across 28 enrollees, it nearly pays for itself.

Ask for a line-item breakdown. Bundled percentage pricing can hide a large markup on workers' comp or state unemployment rates.

PEO vs EOR

Both handle payroll and benefits, so people mix them up.

• Legal entity: a PEO requires you to have one. An EOR does not.
• Employer status: a PEO is a co-employer and you remain the primary employer. An EOR is the sole legal employer.
• Where it is used: PEOs are mostly a US product for domestic employees. EORs are used mostly for hiring in other countries.
• Control: with both, you direct the employee's work.

If you are a US company hiring US staff and want better benefits and less admin, look at a PEO. If you want to hire one engineer in Portugal without opening a company there, use an EOR.

Certified PEOs and compliance notes

The IRS runs a certification program for PEOs, created by the Tax Increase Prevention Act of 2014. A certified PEO (CPEO) must meet financial, background and reporting requirements. When a CPEO pays wages to worksite employees, it is treated as the employer for federal employment tax purposes, meaning it takes on liability for those federal employment taxes. With a non-certified PEO, the client can remain liable if the PEO fails to remit taxes. Ask any provider whether it is IRS-certified.

Co-employment does not move all legal responsibility to the PEO. You are still responsible for workplace safety, how managers treat people, wage and hour decisions you make and compliance with anti-discrimination laws. State rules on PEO licensing and unemployment insurance also vary, so check your states.

Common mistakes and when to leave a PEO

• Assuming the PEO owns compliance. It gives advice and handles filings. Your managers still make the decisions that create legal risk.
• Not reading the exit terms. Leaving a PEO mid-year can reset deductibles for employees and require new state unemployment accounts. Plan exits for year-end.
• Paying for services you do not use. Many companies on a top-tier PEO plan use only payroll and benefits.
• Staying past the point it makes sense. Once you have an HR team of two or three and enough headcount for strong benefit rates on your own, compare the PEO fee with the cost of an HRIS, a benefits broker and a payroll provider.
