ASO Workers' Compensation: What Administrative Services Only Means for Comp Coverage

An Administrative Services Only (ASO) arrangement outsources payroll processing, tax filing, and HR administration to a third-party provider, but unlike a PEO, the client remains the sole employer of record and workers' compensation coverage stays entirely separate. There is no co-employment relationship and no shared master policy. The ASO handles the paperwork; the client still has to secure and manage its own comp policy independently.

ASO vs. PEO: Where Comp Coverage Actually Sits

This is the single most common point of confusion in the market, and it costs real money when it goes wrong. An agent recommends a PEO expecting workers' comp to come bundled with the arrangement, then discovers after bind that the provider is actually structured as an ASO, and the client still has no comp policy in place. Before recommending either option, confirm in writing whether the provider carries a master workers' comp policy for its clients or whether comp placement remains a separate, standalone task.

Who Uses an ASO Instead of a PEO

An ASO makes the most sense for employers with clean workers' comp loss history who do not need a co-employment workaround to manage their mod, larger operations, generally 500 or more employees, where PEO economics get less attractive at scale, and businesses that specifically want to keep workers' comp separate, whether to maintain a relationship with a preferred carrier or to manage a captive or alternative-risk program. For these clients, standalone placement paired with outsourced payroll and HR is usually the better structure.

How CPR Places Standalone Comp for ASO Clients

CPR reviews the loss history, payroll basis, and target states before recommending a market, then places the workers' comp policy directly with a carrier that fits the account's mod and class mix, independent of whatever ASO or payroll vendor the client uses. Because the policy sits outside the ASO relationship, it stays in place even if the client switches administrative providers later. Agents get a dedicated point of contact for submissions and renewals rather than routing everything through a general marketing email.

Frequently Asked Questions

Does an ASO client need a separate workers' comp policy?

Yes. An ASO does not carry a master policy, so the client must secure and maintain its own standalone workers' compensation coverage, typically through an agent or broker.

Is workers' comp coverage ever included in ASO pricing?

No. ASO fees cover payroll processing, tax filing, and HR administration only. Workers' comp premium is billed separately by the carrier holding the policy.

Can a business switch from a PEO to an ASO without losing workers' comp coverage?

Not automatically. Leaving a PEO's master policy means the business needs its own standalone policy in place before the transition date, or coverage will lapse.

How is premium determined for a standalone ASO client's policy?

The same way as any standalone account: audited payroll, class codes, and experience mod, priced directly by the carrier rather than allocated across a master policy's pooled group.
