When Does It Make Sense to Leave a PEO?

When Does It Make Sense to Leave a PEO?

This is for companies with 20 to 99 employees that are in a PEO today.

Nobody should leave a PEO because of an article. Including this one.

A PEO, or professional employer organization, is a company that becomes a co-employer of your team on paper. It runs payroll, files the payroll taxes, carries the workers’ compensation cover and puts your people on its own benefit plans.

Unwinding is the word for leaving one. It means ending the agreement and setting the company up on its own payroll, its own benefit plans and its own workers’ compensation policy.

There is no headcount where a PEO stops making sense. There is no year where it flips. There are only moments when the question is worth asking properly. Here are six of them.

1) You are much bigger than when you signed

This is the big one.

What made sense at 12 employees may not make sense at 42. Not because anything went wrong. Because your size changes what the market will offer you.

At 12 people, your choices were limited. At 42, more doors are open than were open before. That is worth knowing even if you walk through none of them.

2) You hired somebody who can own this

When you joined, maybe nobody could run payroll or answer an HR question.

Now you may have an office manager, a controller or an HR person who could.

That changes the math. A large part of what you pay for is somebody doing a job. If a person on your team is already doing part of that job, you are paying for it twice.

3) You use only part of the bundle

A PEO bundles many services together. The handbook. The advice line. The training. The app. Benefits sign-up.

When you were small you probably used most of it. Now you might use three of those things.

Or the opposite may be true. You might lean on them far more than you realise. That is just as useful to find out.

4) You want more say over the health plan

Inside a PEO you usually pick from the plans the PEO offers. That is simple and simple has real value.

It also means the plan was built for a group of companies, not for yours. If your team keeps asking for something the plan does not do, that is a signal worth following.

5) Your people are in one or two states

Multi-state payroll and compliance is genuinely hard work. If your team is spread across the country, a PEO is carrying something heavy for you.

If everyone sits in New Jersey and Pennsylvania, that particular job is a lot smaller.

6) Nobody has ever compared your renewal

This is the honest one and it applies at any size.

Most owners have never once seen their own company priced on its own, side by side. Not a guess. Not a sales deck. The actual comparison.

You cannot make a good decision about something you have never priced.

What leaving actually involves

If the numbers do point outward, here is the real work. None of it is a reason on its own. All of it needs planning.

The health plan starts over. You buy your own. It is priced for your company alone, not for a whole book of business.

Deductibles can reset. Say you move in the middle of the plan year. What your employees have already paid towards a deductible may not carry across. Some carriers will give credit for it if you ask up front. Ask up front.

Payroll comes home. The company files its own payroll tax returns again, under its own employer identification number.

A certified PEO means a filing. A certified PEO is one that has passed the IRS certification programme. Form 8973 tells the IRS when a contract with a certified PEO starts and when it ends. So the exit has paperwork attached to it.

Workers’ compensation becomes your own policy. Inside a PEO the cover usually sits on the PEO’s policy. Outside, the company buys its own.

Unemployment depends on your state. Experience rating is the score your state gives your company for unemployment insurance, based on claims made by former employees. Inside a PEO, the rate you see usually reflects the PEO’s record rather than only your own. What happens on the way out depends on your state. It also depends on how long you have been in the arrangement. Ask that question early and never assume the answer.

HR, compliance and technology get replaced or bought. Handbook, onboarding, advice, the payroll system, benefits administration, time tracking. Some of it you may already own.

Timing matters more than people expect

The cleanest exits line up with the end of the benefit plan year. That way deductibles do not reset in the middle of it.

An exit also has to respect whatever notice your agreement requires. That is in your contract, not in an article. Read it before you pick a date.

One more thing worth knowing. The rules are not the same in every state. New Jersey registers these companies by name and calls them employee leasing companies. A registered leasing company and its client company are treated as co-employers of the covered employees for wages and benefits.

The answer is sometimes no

Plenty of comparisons come back saying stay. That is a real answer and a good one.

Leaving is not better. Staying is not better. One of them is better for your company this year. The only way to know is to see both.

The thing that actually costs money

Not the PEO. Not leaving the PEO.

Renewing for another year without ever running the numbers.

That is the Cost of Doing Nothing. Nothing breaks. Nobody complains. The invoice arrives, it is a bit higher, somebody approves it and the year starts again.

Where to start

Two documents and you probably have both.

Your latest PEO invoice or renewal. And your employee census, which is just a list of your team with dates of birth, zip codes and who they cover. No conditions, no Social Security numbers.

The census goes through pennworth.com/secure-upload, never by email. It holds personal information about your people, so it travels the safe way.

Send those two and you get a PEO Benchmark Analysis. That is a side-by-side report. What your company pays and gets inside the PEO, against what the same company would look like outside it.

No switching. No notice. No decision at the end of it unless you want one.
