Simplify ACA Reporting with Our Affordable and Accurate Solution

Applicable Large Employers (ALEs) with over 50 full-time employees face Affordable Care Act (ACA) compliance mandates. This includes offering affordable, minimum essential coverage with minimum value to full-time employees and their dependents. Additionally, distributing 1095 forms to all full-time and covered employees and transmitting information to the IRS through Form 1094 are essential components of ACA compliance.

Controlled Group Considerations:

For small employers affiliated with larger organizations, ACA requirements may apply if the small employers are part of a controlled group. Understanding the ACA controlled group rules is important for organizations with multiple employer identification numbers (EINs) to identify which EINs fall under ACA requirements. In a controlled group scenario, all employees across the group members are counted in determining the 50 full-time employee threshold for ALE status.

Employer Shared Responsibility and Controlled Groups:

The employer shared responsibility rules consider an employer part of a controlled group if there is a common owner or another form of relation. Controlled groups fall into three categories: Parent/Subsidiary, Brother/Sister, and Combined.

  • Parent-Subsidiary Controlled Group: Linked through stock ownership with a common parent, this group requires 80% of the stock of each company to be owned by one or more group members. The parent must own at least 80% of one other company.
  • Brother-Sister Controlled Group: Formed when one or more companies hold a controlling interest of 80% or more in the stock of each corporation. Alternatively, a brother-sister group may arise when there is effective control, and more than 50% of the stock of each corporation is jointly owned.
  • Combined Controlled Group: Comprising three or more companies organized such that each is a member of either a parent-subsidiary or brother-sister group, with at least one corporation serving as the common parent of both groups.

Reviewing Affiliated Companies:

Employers initially categorized as small employers should diligently review their affiliated companies to determine if they fall under the controlled group classification and are therefore subject to ACA requirements.

In navigating the intricate landscape of ACA compliance and controlled group considerations, employers must stay informed, conduct comprehensive reviews, and adhere to the guidelines to ensure proper adherence to the Affordable Care Act.
