PayAdvisors vs a PEO: Co-Employment or Your Own Payroll Team
A PEO (professional employer organization) becomes a co-employer of your staff. It pays your people and usually reports payroll taxes under its own EIN, and it often bundles health benefits and workers' comp. PayAdvisors does not co-employ anyone. Our payroll team runs your payroll under your own EIN, you stay the only employer, and you approve every run.

In short
Which one fits you?
Choose a PEO if your main goal is access to a pooled health plan or workers' comp through a larger group, you have no HR person, and you are comfortable sharing the employer role and moving your people onto the PEO's payroll and plans.
Choose PayAdvisors if you want to stay the employer of record, keep your own EIN, benefits broker and plans, and you mainly need the payroll work done right every pay period, by a team, without hiring a payroll person.

IRS rules
Who files, and who is liable, under IRS rules
The IRS sorts outside payroll help into a few types, and the type decides whose EIN is on the returns and who carries the tax liability:
- Payroll service provider or reporting agent: files a separate return for each client using the client's own EIN, and deposits the client's taxes. The employer stays liable for making sure returns and deposits are on time.
- Certified PEO (CPEO): pays wages to the workers under a CPEO contract and files aggregate returns under the CPEO's own EIN, including the federal unemployment (FUTA) return. The IRS says a CPEO is generally solely liable for the employment taxes on wages it pays to worksite employees.
PayAdvisors works the first way: your payroll stays under your EIN, in your accounts. That is why there is nothing to move back if you ever change providers. See payroll tax filing and compliance.
Not every PEO is certified. Certification is a voluntary IRS program, and the IRS keeps a public list of certified PEOs. Ask any PEO whether it is certified and how it reports your taxes.
Fair view
When a PEO is the better fit
A PEO can make sense when access to a large-group health plan matters more to you than keeping the employer role, when you want payroll, benefits, workers' comp and HR in one contract, and when you have no one in-house for HR. NAPEO, the PEO industry association, says about 14 percent of employers with 20 to 499 employees use a PEO.
If what you really need is payroll done right, on time, by people who know your file, a PEO is more than you need. You can keep your own plans and broker, and hand us the payroll. Need HR help too? Our HR consulting comes from the same team. See also hire vs outsource payroll.
Leaving a PEO
Already in a PEO?
Leaving a PEO means new state tax accounts, a payroll platform and benefit deductions to set up before your first payroll on your own. We plan back from your PEO end date, register your state accounts and run the first payroll after the PEO. See PEO exit payroll and our state payroll tax registration guides.

PayAdvisors vs PEO questions
What is the difference between a PEO and a payroll service?
A PEO becomes a co-employer of your staff and usually reports payroll taxes under its own EIN, often with its own benefit plans and workers' comp. A payroll service like PayAdvisors runs your payroll under your EIN, and you stay the only employer.
Is PayAdvisors a PEO?
No. We do not co-employ anyone. Our payroll team runs your payroll, files your payroll taxes and handles agency notices, and you approve every run.
Can I keep my own health plan and broker with PayAdvisors?
Yes. You keep your plans and your broker. We handle the payroll deductions and coordinate with your broker so plan changes do not break payday.
Who is liable for payroll taxes with a PEO?
It depends on the arrangement. The IRS says a certified PEO is generally solely liable for employment taxes on wages it pays to worksite employees. With a payroll service provider, the employer remains liable for timely filings and deposits, which is why we build buffer time in before every deadline.
What happens to our state tax accounts if we leave a PEO?
If the PEO reported under its own accounts, you usually need your own state withholding and unemployment accounts before your first payroll on your own. We register them and track each one until it is issued. See PEO exit payroll.
Is there a minimum commitment with PayAdvisors?
No. Service is month to month, with no minimum term.
