ICHRA vs PEO

What is a PEO?

A professional employer organization enters a co-employment relationship with your business, becoming the employer of record for certain purposes. Through that arrangement, the PEO pools your employees with those of other clients to offer group health insurance, and typically bundles payroll, HR administration, workers' compensation, and compliance support — for a fee, often a percentage of payroll or a per-employee charge.

It is a large, established industry. NAPEO's industry footprint report counts 523 PEOs in the United States serving more than 208,000 clients with 4.5 million worksite employees and $308 billion in payroll (2022 data, published 2023). Roughly 17% of all businesses with 10–99 employees use one, and the average client has about 22 worksite employees — which is to say the PEO's core customer is the same small employer that considers an ICHRA.

"PEO insurance" usually means the health coverage that comes with that co-employment relationship, though the phrase also gets used for the rest of the bundle — workers' compensation and employment practices liability written under the PEO's policies. On the health side, the PEO is the plan sponsor and the policyholder of a master group contract; your employees enroll as members of the PEO's pooled group, not as a plan your business owns. That is the structural fact that drives everything else on this page: the plan menu, the renewal pricing, and what happens to coverage if you leave are all decided at the PEO level.

What is an ICHRA?

An Individual Coverage HRA is not a co-employment arrangement or a bundled service. It's a benefit: you set a monthly allowance, employees buy their own individual health plans, and you reimburse them tax-free. You remain the sole employer, and you control the benefits budget directly.

The core difference

A PEO gives you access to a pooled group health plan and a suite of outsourced HR services under co-employment. An ICHRA gives you a fixed, tax-free budget to fund individual coverage your employees choose, with no co-employment and no bundled services. One outsources employment administration; the other modernizes just the health benefit.

What PEO health insurance actually costs

A PEO's health benefit has two layers, and employers often see only one on the invoice. The first is the premium for the PEO's pooled group plan. Because the PEO is the plan sponsor, that plan renews on the PEO's terms: the rate action is set by the carrier and the PEO's pool, not by your own claims, and it lands with the same annual renewal increases as any group plan — the KFF 2025 survey put the average family premium for employer coverage at $26,993, up 6% in a year. The second layer is the PEO's service fee, charged as a percentage of payroll or a per-employee-per-month amount. Ask for it broken out; a percentage-of-payroll fee rises automatically with every raise you give.

An ICHRA has one layer you set — the allowance — plus administration. Most ICHRA administrators charge in the range of $14 to $85 per employee per month, sometimes with a setup fee (see our ICHRA administration cost guide). There is no payroll-linked fee, and there is no renewal, because there is no group plan to renew.

How the administrative layer is priced varies, and it changes what health coverage really costs you. Some PEOs charge a flat per-employee-per-month fee; others charge a percentage of total payroll, which means the cost of the same benefits rises every time you give a raise. Health premiums are then re-rated by the PEO at each renewal, and because your group is inside their pool, your own claims experience is not what sets your rate — the pool's is. Ask for the two layers separately in writing before comparing a PEO against an ICHRA, where the allowance is the only number and you set it.

Health coverage: pooled vs. individual

With a PEO, employees enroll in the PEO's group plan — a defined menu chosen by the PEO. With an ICHRA, employees choose any individual plan in their area, so coverage is personalized and portable. If broad plan choice matters to your team, ICHRA has the edge; if you want a single managed plan handled for you, a PEO's group option may appeal.

Why employers leave a PEO's health plan — and what it takes

Because the PEO is the plan sponsor, your employees' health coverage is tied to the co-employment contract. That creates the three situations that push employers out. The first is a renewal you cannot negotiate: the PEO's pool took a rate action, and your only levers are to accept it, shift cost to employees, or leave. The second is a workforce the pooled plan does not fit — remote or multi-state staff outside the plan's network, part-time or seasonal workers who fail participation rules, or a team that has simply outgrown one carrier menu. The third is the fee itself, once payroll has grown enough that a percentage-of-payroll charge outstrips the HR work it buys.

Leaving is a benefits event, not just a vendor change. When the co-employment ends, so does the group plan, so the exit has to be sequenced: new payroll live, a new health benefit in place with its own enrollment window, and — if that benefit is an ICHRA — the plan document adopted and the employee notice delivered before the plan year starts. Loss of the PEO's group coverage is a qualifying event that opens a special enrollment period for individual plans, which is what makes a PEO-to-ICHRA move workable mid-year. The HRA Council's Vol. 5 report (August 2026) notes that nearly a third of small employers adopting an ICHRA came from the small-group market; a PEO's pooled plan is a form of that market.

Control and flexibility

An ICHRA gives you direct control over the benefits budget and lets you vary allowances by employee class. A PEO trades some of that control for convenience — you get bundled services, but you're inside the PEO's systems, plan menu, and pricing, and leaving a PEO can mean untangling payroll and benefits.

HR and payroll services

This is the PEO's real strength. Beyond health insurance, a PEO handles payroll, HR compliance, workers' comp, and often benefits administration in one package. An ICHRA does none of that — it's purely a health benefit. If you want to outsource HR broadly, that's a point for the PEO; if you only need a better health benefit, the ICHRA is far more focused.

When a PEO makes sense

A PEO can be a good fit if you want to outsource HR, payroll, and compliance as a bundle, value access to a pooled group plan, and are comfortable with co-employment and the associated fees. Businesses that want to hand off employment administration wholesale often choose a PEO.

When an ICHRA wins

An ICHRA tends to win when your priority is the health benefit itself: predictable, controllable cost, employee choice, no participation minimums, and no co-employment. Employers who already have payroll handled — or who don't want to bundle it — often find an ICHRA a simpler, more flexible, and more transparent way to offer coverage.

Can you use both?

In some cases, yes — a business might use a PEO for HR and payroll while offering an ICHRA for health benefits, though not every PEO supports it and the setup needs care to avoid conflicts. If you like your PEO's services but not its group plan, it's worth asking whether an ICHRA can sit alongside it.
