We Are Several Entities Under Common Ownership. How Does That Work?
It is worth settling early, because the answer may not be the one the org chart implies.
Related companies can be treated as a single employer for some benefits purposes, which affects large-employer determination, reporting and testing even where the entities run independently and have separate plans. Getting that read right is usually a conversation with counsel or your accountants rather than a benefits question, and it is one of the few things genuinely worth doing before anything else.
What Is Actually True for Related Companies
What Is Actually True
- Businesses under common ownership are generally treated as one employer when the fifty-employee threshold is measured.
- Each member of the group carries the obligation in its own name, even though the count is combined.
- Nondiscrimination testing can run across the related group, which bites harder at the smaller entities.
- Separate payrolls and separate carriers do not change how the group is counted.
What CFH Does About It
- We map the entities and ask your counsel or accountants to confirm how they are grouped.
- We build the benefits calendar around the combined count.
- We design plans and contributions with the testing in mind.
- We coordinate reporting across the entities.
Where Common Ownership Matters
Four places the combined count shows up.
Three small entities may be one large employer for the mandate.
What we do about it: We count the group before we count the entity.
Each entity files in its own name, from a shared set of facts.
What we do about it: We keep the offer record consistent across them.
What one entity offers can affect testing for the others.
What we do about it: We design with the group in view.
A transaction changes the count, the carrier and sometimes the plan.
What we do about it: We plan the transition before the deal closes.
Questions We Hear From Related Employers
Do We Need One Plan or Several?
Either can work. The better question is what each choice does to cost, testing and administration, which we model for you.
Who Decides How We Are Grouped?
Your counsel or accountants. We bring the benefits consequences to that conversation.
Can One Carrier Cover All the Entities?
Often, yes, and sometimes it helps. We compare the options on the whole group.

Common Ownership: The Detail
Several companies with the same owners can be treated as one employer for benefits purposes. These are the rules that matter.
Controlled-Group Rules Aggregate Employers
Under federal tax rules, businesses with common ownership can be treated as a single employer. Whether a particular set of businesses counts as one employer depends on ownership details and the tax rules, so the determination belongs with the company’s attorney or tax adviser, not the benefits broker.
Headcount Is Combined for the ACA
Employees across the group are added together when deciding whether the 50-employee threshold is met. That combined count affects which employer obligations apply, so confirm the grouping with counsel before relying on any one entity’s headcount for planning. Ask for that confirmation in writing.
Each Entity Still Has Its Own Filings
Even when combined for the threshold, each entity has its own reporting responsibility. Plan for each entity’s own forms, deadlines and recordkeeping, and decide in advance who collects the information from each, so nothing is missed during the busy season. A shared calendar helps.
Plan Design Can Be Shared or Separate
Related companies can offer one plan or several, but nondiscrimination and offer rules still apply. Separate plans for different entities may raise fairness questions across the combined group, so review the design with benefits counsel before finalizing it. Keep a record of the reasoning behind the structure you choose.
Common Questions About Common Ownership
What is a controlled group?
A group of businesses linked by common ownership that the tax rules treat as one employer for certain purposes.
Does it affect ACA size?
Yes. Employees across the group are combined to decide whether you are an applicable large employer.
Who files Forms 1094-C and 1095-C?
Each member of the group files for its own employees.
Can we have one plan for all companies?
Yes, in many cases. Structure should be reviewed.
What about family-owned businesses?
Attribution rules can link family members’ ownership. Review is needed.
Does it matter for retirement plans?
Yes, coverage and testing rules also apply across the group.
How do we find out if we are in a controlled group?
Review the ownership structure with your attorney or CPA.
Can a controlled group avoid ACA penalties by splitting?
No, splitting entities does not avoid aggregation rules.
Can you help sort this out?
We can map the structure and the benefit implications. Your attorney confirms the legal determination.
