ACA Compliance During Mergers, Acquisitions, and Business Reorganizations

Mergers, acquisitions, divestitures, and corporate reorganizations often focus on financial, legal, and operational integration. However, these transactions can also create unexpected Affordable Care Act (ACA) compliance challenges. Changes to payroll systems, legal entities, employee classifications, or benefits administration can affect ACA reporting and increase the risk of inaccurate Forms 1095-C or potential IRS penalties.

Whether your organization is acquiring another company, selling a business unit, or simply restructuring operations, HR and Payroll should be involved early in the planning process.

Preserve Employee History

One of the most common ACA issues occurs when employee records are transferred to a new payroll or HR system. During a conversion, important historical information can be lost or inadvertently changed.

Before completing a system conversion, confirm that key data such as the following will be preserved:

• Original hire dates
• Employment status history
• Hours of service
• Full-time status determinations
• Offers of coverage
• Coverage effective dates

Incomplete historical data can make ACA reporting significantly more difficult at year-end.

Understand Who Is Responsible for Reporting

Business transactions often involve multiple legal entities and employer identification numbers (EINs). HR should confirm which entity is responsible for offering coverage and issuing Forms 1095-C.

Questions to consider include:

• Has responsibility for employees shifted to a different EIN?
• Are employees transferring between related employers?
• Will payroll and benefits administration remain under the same entity?

Identifying reporting responsibilities early helps avoid duplicate reporting or missed reporting obligations.

Review Employee Classification Changes

Organizational changes frequently affect how employees are classified.

For example:

• Employees may transfer between locations or entities.
• Part-time employees may become full-time.
• Seasonal or variable-hour employees may move into different positions.
• Employees may appear to be terminated and rehired when they have actually transferred within the organization.

These changes can affect eligibility tracking, offers of coverage, and ACA reporting.

Coordinate Payroll, HR, and Benefits Administration

ACA compliance depends on accurate data flowing between payroll, HR, and benefits administration systems. During a merger or reorganization, changes to payroll vendors, HRIS platforms, or benefits administrators increase the possibility of data inconsistencies.

Before year-end, employers should verify that:

• Employee demographic information is accurate.
• Payroll and eligibility files reconcile.
• Coverage elections transferred correctly.
• Employee contribution amounts remain accurate.
• Offer of coverage information is complete for the entire reporting year.

Identifying discrepancies early is much easier than trying to correct reporting errors after Forms 1095-C have been prepared.

Don’t Overlook Affordability

Corporate transactions sometimes result in new benefit plans, different employee contribution amounts, or changes to payroll frequencies. Employers should review whether employee contributions continue to satisfy the ACA affordability requirements under their selected affordability safe harbor.

Employer Takeaway

Corporate transactions involve much more than combining payrolls and benefit plans. They also require careful attention to the employee data used for ACA compliance and reporting. By involving HR, Payroll, Benefits, and your benefits administration partners early in the process, employers can help preserve historical information, maintain accurate reporting, and avoid unnecessary compliance issues at year-end.
