Co-Employment Explained for Brokers: What Changes When a Client Joins a PEO

Brokers who place a client with a PEO for the first time tend to get one of two surprises a few months later. Either the client calls asking why their old carrier sent a short-rate bill, or the client calls asking why the PEO's carrier is quoting them as if their experience mod does not exist. Both calls are avoidable. Both come from the same gap: nobody walked the client through what actually changes, legally and on the insurance side, the day they sign the client service agreement.

This post is the walk-through. It is written for brokers, but PEO sales reps should read it too, because the broker is usually the one setting the client's expectations and the PEO is usually the one living with them.

Who is the employer of what

Co-employment splits the employer role between two parties by contract. The PEO becomes the employer of record for a defined set of administrative functions: it runs payroll under its own tax identification numbers, files and remits employment taxes, administers benefits, and in most arrangements sponsors the workers' compensation coverage. The client retains direction and control of the work. Hiring, firing, scheduling, supervision, job assignments, and the actual operation of the business stay with the client.

That split is the whole point, and it is also where brokers should be precise with language. The PEO does not "take over" the employees. The client does not "outsource HR." Each party is an employer for the purposes the contract assigns, and the client service agreement is the document that defines who holds which obligation. A broker who has not read the CSA for the PEO they are recommending is recommending a contract they have not seen.

Two consequences follow for insurance. First, the PEO's carrier is underwriting the client's operations, not the PEO's office, so the client's class codes, payroll, and loss history still drive the price. Second, when the employment-law obligations are allocated to the PEO, the PEO's compliance performance becomes the client's exposure, which is why the quality of the PEO's payroll and HR operations is an underwriting question for the broker as much as a service question for the client.

How the coverage is actually written

This is where state rules matter and where a lot of broker explanations go wrong by generalizing from one state to another.

In NCCI states and many others, the common structure is a master policy. The PEO is the policyholder; the carrier adds each client as an insured under the master, the PEO reports payroll by client and class, and the client receives a certificate. The client never holds its own policy. Variations exist, including the multiple coordinated policy structure where each client has its own policy number under a PEO program, and client-secured coverage where the client keeps its own policy and the PEO is added to it.

California is different, and brokers placing California clients should know it. The WCIRB's Experience Rating Plan, Section V, Rule 4, requires that a separate workers' compensation policy be written for workers provided to a client under an employee leasing arrangement. The client's own experience modification applies to that policy, and the experience generated under it counts toward the client's future ratings, not the PEO's. A policy covering only the PEO's own staff must exclude the leased workers. The rule carves out short-term temporary staffing arrangements, which are treated differently.

The practical meaning is that in California a client's mod follows the client into and out of the PEO relationship. In a master-policy state, that is not always true, and a broker needs to ask the PEO how the program handles it, which brings us to the mod question.

What happens to the client's mod

Under a master policy, especially a large-deductible one where the PEO is retaining most of the loss, the carrier is pricing the PEO's aggregate book. The client's individual experience mod may not be applied at all; the PEO sets the client's rate inside its own pricing model, using the mod as an input to that model rather than as a multiplier on a manual rate. A client with a 0.78 mod may be told, truthfully, that the PEO's carrier does not use their mod, and a client with a 1.40 mod may be told the same thing. One of those clients is getting a good deal and one is subsidizing the book.

Brokers should ask three questions before placing a client. Does the carrier apply the client's mod to the client's premium, or does the PEO price the client internally? If the client leaves the PEO, what loss history will the next carrier see, and under whose name? And how does the PEO report the client's payroll and losses to the rating bureau, so that the client's rating record stays intact?

That last point is easy to overlook. A client that spends three years under a master policy in a state where the experience is reported under the PEO may come out the other side with a gap in its own rating history. The next carrier then rates the client on incomplete data, or with a unity mod that erases a good record. In California the separate-policy rule largely prevents this. Elsewhere, it depends on the program.

The mid-term cancellation problem

The client almost always has a workers' comp policy in force when it signs with a PEO, and that policy almost never expires on the PEO's start date. Something has to happen to it.

The clean path is to align the PEO start date with the existing policy's expiration, and brokers who control the timing should push for it. When that is not possible, the client cancels mid-term, and most carriers apply a short-rate penalty for insured-initiated cancellation. ICW Group's California short-rate disclosure, for example, states that the fee can run up to 100 percent of one year's premium and walks through the standard NCCI short-rate table, under which a cancellation about 30 days into the term carries roughly a 19 percent charge and one about 100 days in carries roughly 38 percent. The disclosure also shows the mechanics: annualize the earned premium, apply the table percentage, and the difference between that and the pro-rata earned premium is the penalty.

Whether a particular carrier applies short-rate, and whether it waives it for a PEO transition, varies. Some carriers treat a move to a PEO as pro-rata. Many do not. The broker should get the answer in writing from the incumbent carrier before the client signs anything, because the client will remember who told them the switch was free.

A note on the other direction: California Insurance Code section 676.8 limits the grounds on which an insurer can cancel a workers' comp policy mid-term to things like non-payment, failure to report payroll or submit to audit, material changes in operations, and misrepresentation, with ten or thirty days' notice depending on the ground. It does not address employer-initiated cancellation, so the short-rate question is a matter of the policy's own terms.

What else moves on day one

A few items that are not insurance but that brokers get asked about anyway.

Payroll taxes restart under the PEO's accounts, and in many states the wage-base clock restarts with them unless the PEO is operating under a successor arrangement; the client should ask the PEO how it handles FUTA and SUTA wage bases on a mid-year transition. Benefits plans move to the PEO's sponsored plans, which can mean a new deductible year for employees. Existing employee handbooks and policies may need to be reconciled with the PEO's requirements. And the client's own HR and payroll staff do not disappear; their jobs change, and clients with a payroll manager who has done it for fifteen years will have opinions about that.

None of these are reasons not to place the client. They are reasons to set expectations before the first payroll rather than after.

What a broker should set expectations on

If we had to reduce two decades of these conversations to a short list, it would be this.

The client keeps control of the work and the people. The PEO takes the administrative employer role. The CSA defines exactly which is which.

The client's workers' comp coverage will be written differently, and in California it will be a separate policy under the client's own mod. In other states, ask how the mod is applied and how the client's experience is reported.

The client's existing policy has to be cancelled or allowed to expire, and cancelling it early can cost real money. Get the incumbent carrier's short-rate position in writing.

If the client ever leaves the PEO, their loss history should be intact and attributable to them. Ask the PEO how it ensures that.

Brokers who cover those four points up front do not get the surprised phone calls, and PEOs that work with those brokers close faster because the client arrives already understanding what they are buying.

We built HALO IQ so that brokers and PEOs work the same deal from their own side of it, and the co-employment handoff is a good example of why that matters. The broker brings the client's policy dates, current carrier, and mod worksheet; the PEO brings its program structure and pricing. When both sets of facts sit in the same client workspace in ConnectIQ, the mid-term cancellation question and the mod question get answered before the proposal goes out, not after the first invoice.
