Aggregated ALE Group: Combination Tests, Reporting, and Penalties

An aggregated ALE group is a set of related businesses that the IRS treats as one employer when testing whether the Affordable Care Act’s employer mandate applies. If the combined full-time and full-time-equivalent headcount across the related entities reaches 50, every entity in the group becomes an ALE member, even one with a handful of workers on its own payroll. Each member then has to offer qualifying coverage and file its own information returns, and each faces its own penalty exposure if it doesn’t.¹

How the 50-Employee Count Works

An employer is an Applicable Large Employer for a calendar year if it averaged at least 50 full-time employees, including full-time equivalents, during the prior calendar year. A full-time employee is anyone averaging at least 30 hours of service per week or 130 hours per month.¹

Part-time hours count too, through the full-time-equivalent calculation. For each month, add the hours of service for all non-full-time employees (capping each worker at 120 hours), then divide the total by 120. Twenty part-timers logging 60 hours each in a month produce 1,200 hours, which divided by 120 gives 10 full-time equivalents added to the actual full-time headcount for that month.¹

One narrow off-ramp exists. A business that only crosses 50 because of seasonal hiring may avoid ALE status if the workforce exceeded 50 for no more than 120 days during the prior calendar year and every employee above the threshold during that window was a seasonal worker. The IRS defines seasonal workers by reference to the Department of Labor’s definition, plus retail workers employed exclusively during holiday seasons, and lets employers apply a reasonable, good-faith interpretation.²

Which Related Businesses Get Combined

A single business under 50 employees might assume the mandate doesn’t reach it. But if it shares common ownership or control with other entities, the IRS looks at all of them together. Companies related under the controlled group rules in Internal Revenue Code Section 414 are combined and treated as a single employer for ALE testing. When the combined count meets or exceeds 50, every member of the group is an ALE member, regardless of individual size.¹

The rules pull their definitions from IRC Section 1563 for corporations and parallel regulations for partnerships, sole proprietorships, and other unincorporated businesses under IRC Section 414(c). They exist precisely to keep owners from splitting a workforce across separate legal entities to stay under 50.³

Parent-Subsidiary Groups

A parent-subsidiary group exists when one corporation owns at least 80 percent of the voting power or share value of another. The parent must directly own 80 percent of at least one subsidiary, and each subsidiary in the chain must be 80 percent owned by one or more of the other group members. If Company A owns 85 percent of Company B and Company B owns 90 percent of Company C, all three form one controlled group.⁴

Brother-Sister Groups

A brother-sister group arises when five or fewer individuals, estates, or trusts own more than 50 percent of two or more corporations, counting only the ownership that is identical across each corporation. Identical ownership means the smallest stake each person holds in any of the corporations. When identical ownership across five or fewer people exceeds 50 percent, the corporations are a brother-sister group.⁴

Combined Groups

A combined group involves three or more corporations where at least one is a common parent in a parent-subsidiary group and is also a member of a brother-sister group. These structures show up in larger family businesses with overlapping ownership layers.⁴

Affiliated Service Groups

Controlled group rules are not the only route to aggregation. IRC Section 414(m) reaches affiliated service groups, which commonly affect professional practices and other service businesses. An affiliated service group forms when a service organization has a relationship with another organization that is a shareholder or partner in it and regularly performs services for or alongside it. A separate rule captures management organizations whose principal business is performing management functions on a regular basis for another entity. Either way, all employees across the group are treated as employed by a single employer.³

Beyond these categories, IRC Section 414(o) gives the IRS authority to issue regulations targeting arrangements that use separate organizations, employee leasing, or other structures designed to avoid coverage requirements. Creative restructuring to stay under 50 rarely holds up.³

What Each Member Owes Once the Group Is an ALE

Once a group crosses the threshold, each member has to offer affordable, minimum-value health coverage to at least 95 percent of its full-time employees and their dependents. Each member is individually responsible for its own shared responsibility payment. The IRS does not impose joint liability across the group, so if Company A fails to offer coverage while Company B complies, only Company A owes a penalty.⁵

The Affordability Standard for 2026

Coverage is “affordable” only if the employee’s required contribution for self-only coverage does not exceed a set percentage of household income. For plan years beginning in 2026, that percentage is 9.96 percent, up from 9.02 percent in 2025.⁶

Because employers rarely know an employee’s household income, three safe harbors substitute for the actual test. The W-2 safe harbor holds if the employee’s share of self-only premiums doesn’t exceed 9.96 percent of Box 1 wages. The rate-of-pay safe harbor uses the hourly rate times 130 hours per month for hourly workers, or monthly salary for salaried workers. The federal poverty line safe harbor uses the single-person poverty figure divided by 12. Satisfying any one protects the ALE member from an affordability penalty for that employee, even if coverage would technically be unaffordable against actual household income.

Reporting on Forms 1094-C and 1095-C

Every ALE member in an aggregated group has to file its own annual information returns, no matter how small it is on its own. Form 1095-C goes to the IRS for each full-time employee, reporting the coverage offered (or not) for each month. Form 1094-C is the transmittal that accompanies the batch and summarizes workforce data. Members of an aggregated group must check the aggregated group indicator on the 1094-C and list the other members in Part IV.⁷ Each member also has to furnish a copy of Form 1095-C to every full-time employee.⁸

For 2025 calendar year reporting filed in 2026, employee statements are due March 2, 2026. Paper filings with the IRS are also due March 2, 2026; electronic filings are due March 31, 2026.⁷ Any employer required to file 10 or more information returns during the year (all types combined, including W-2s) must file electronically, a bar virtually every ALE member clears because each full-time employee generates a separate 1095-C.⁹

What Noncompliance Costs in 2026

Failing to offer coverage triggers one of two penalty tracks under IRC Section 4980H, often called the “pay or play” provisions.⁵

Under Section 4980H(a), if an ALE member does not offer minimum essential coverage to at least 95 percent of its full-time employees and even one full-time employee enrolls in a marketplace plan with a premium tax credit, the 2026 penalty is $3,340 per full-time employee per year, minus the 30-employee reduction. Under Section 4980H(b), if the member does offer coverage but it fails the affordability test or does not provide minimum value, the 2026 penalty is $5,010 per year for each full-time employee who enrolls in marketplace coverage with a premium tax credit. The (b) penalty is capped at what the employer would have owed under (a). Both amounts adjust annually for inflation.¹⁰

The 30-Employee Reduction Is Shared

The 30-employee reduction is where aggregated group status really bites. The group gets one reduction of 30 employees, not one per member, and the IRS allocates it proportionally to each member’s full-time headcount. If Company A has 60 full-time employees and Company B has 40, Company A gets 18 of the 30 (60 percent) and Company B gets 12 (40 percent). A small member that expected the reduction to zero out its penalty may find it only receives a fraction of the 30.²

Reporting Penalties Are Separate

Independent of the coverage penalties, the IRS charges per-return penalties for late, missing, or incorrect 1094-C and 1095-C filings, and for failing to furnish correct statements to employees. For returns due in 2026: $60 per return if corrected within 30 days of the due date, $130 per return if corrected after 30 days but before August 1, and $340 per return if not corrected by August 1. Intentional disregard runs $680 per return with no annual cap.¹¹ Annual caps apply to the other tiers, and those caps are lower for employers with gross receipts under $5 million. An incorrect 1095-C filed for 200 workers can mean $68,000 in reporting penalties alone, separate from any coverage penalty.

When Group Membership Changes Mid-Year

Acquisitions and new entity formations can shift ALE status inside a calendar year. When an ALE acquires a non-ALE business, the acquired entity generally becomes an ALE member on the acquisition date, even if it keeps its own employer identification number. From that date, the new member has to comply with the mandate and the reporting rules for the rest of the year. A company with 30 employees that has never touched the ACA can find itself filing 1095-Cs because a larger group bought it. Any change of ownership at 80 percent or more, or a restructuring that creates common control, is worth an immediate ALE status review.
