How a PEO Handles ACA Compliance: What the Employer Still Owes
A PEO can run a health plan and package the ACA paperwork, but the employer responsibility remains yours. Who is an applicable large employer, what you offered, and whether it met the bar are questions the PEO frames — not answers it supplies.
The structure this sits on
Under a PEO, the health offering runs through the PEO's benefit plans inside a co-employment arrangement. The PEO administers; the legal obligations for the mandate and reporting trace along the employer that the records actually describe. See co-employment for how those obligations split.
Who gets measured
The rules measure employees to decide whether you are an applicable large employer and which workers count as full-time. The key question is which entity each employee is treated as belonging to under the operation. In practice, that test falls on the worksite employer, not on the PEO that runs the paperwork.
The practical rule: the PEO runs the machinery, but determining your own count and deciding which offer you extend is a decision you own. Relying on the average to carry it is the mistake to avoid.
What the PEO actually handles
- Moves the benefit administration and carrier work off your desk.
- Collects enrollment data and can generate the ACA reporting records.
- Coordinates with you on what the filing reflects.
None of it changes the two numbers that matter: your headcount basis and whether your cost to the employee cleared the bar. A PEO cannot certify you are compliant; it can help you execute.
What you still own
- Your own headcount and any ALE determination, on your facts.
- The offer you actually make and its value to the employee.
- That the data in a PEO-managed filing matches your records.
If a PEO says it "owns all of it", that is the one claim the agreement cannot deliver — because the obligation is attached to the employer, not to the vendor.

Frequently asked
Does a PEO make me compliant with the ACA?
No. It administers the plan and can help with filings, but whether you are an applicable large employer and how you offered coverage is your responsibility as the employer of record.
Who issues the 1094 and 1095 forms?
Typically your PEO coordinates the filing. The data behind it - your full-time count and the offer details - has to be accurate on your side, because the report only reflects what it is fed.
Does the PEO absorb my ACA penalty exposure?
Not by itself. The mandate attaches to the employer interest. A PEO helps you comply but does not lift that obligation off you.
