401(h) Plans and Form 5500: What Gets Reported and Where

A critical aspect of 401(h) plans is that they do not operate as independent entities for reporting purposes. Instead, a 401(h) account is always an incidental feature of an underlying qualified pension or annuity plan. This means that when it comes to annual reporting to the Department of Labor (DOL) and the IRS, the 401(h) doesn't file its own separate Form 5500.

All the necessary information regarding the 401(h) — including its assets, liabilities, and benefit payments — is woven into the Form 5500 filing of the primary qualified plan. This integrated approach simplifies reporting by avoiding redundant filings but requires careful coordination to ensure all aspects of the 401(h) are accurately represented within the larger plan's disclosure.

Given its integrated nature, the financial and actuarial details of a 401(h) plan are reported across various schedules within the main plan's Form 5500. Understanding these specific touch points is essential for accurate reporting and compliance.

For instance, the plan's asset schedules will reflect the balances specifically allocated to the 401(h) account. These assets are segregated within the trust but are reported as part of the total plan assets. Similarly, actuarial schedules are crucial for capturing the projected liability stream associated with the retiree medical benefits provided through the 401(h). This includes assumptions about healthcare costs, participant demographics, and benefit payout patterns.

Finally, benefit-payment schedules will incorporate the actual retiree medical benefits paid out from the 401(h) account during the plan year. These payments are distinct from retirement plan distributions but are reported alongside other plan disbursements, clearly identified as medical benefits.

A fundamental rule for 401(h) plans is the strict requirement for a segregated account. While the 401(h) is part of the broader qualified plan for reporting, its assets must be held in a separate account within the plan's trust, distinct from the pension or annuity assets. This segregation is critical for several reasons:

Firstly, it ensures that the funds designated for retiree medical benefits cannot be diverted to provide pension benefits, and vice-versa. This protects both benefit streams. Secondly, it facilitates precise tracking of contributions, earnings, and distributions attributable solely to the 401(h), which is vital for accurate Form 5500 reporting. The segregated account's financial activities are what populate the specific lines on the asset and benefit schedules.

Contributions to a 401(h) account are subject to specific IRS limits, which also impact how they are reflected on Form 5500 schedules. The most significant rule is that annual employer contributions to the 401(h) portion cannot exceed 25% of the employer's total contributions to the pension or annuity plan (excluding contributions to fund past service credit) for the same year. This limit is a critical factor in plan design and ongoing compliance.

Exceeding these contribution limits can lead to adverse tax consequences and jeopardize the qualified status of the 401(h) component. When reported on Form 5500, these contribution amounts are carefully tracked and must align with the prescribed limits, ensuring both deductibility for the employer and the tax-advantaged status of the participant benefits. Actuarial certifications often confirm adherence to these funding rules.

Despite the integrated nature of 401(h) reporting, several common issues can lead to errors and compliance challenges on Form 5500. One primary source of problems is inconsistencies between actuarial and Third-Party Administrator (TPA) records. Actuaries typically provide the medical liability valuations and contribution recommendations, while TPAs handle the day-to-day administration, asset tracking, and benefit payments.

Discrepancies can arise if these two parties are not in constant communication or if their data doesn't reconcile. For example, asset balances reported by the TPA might not match the assumptions used by the actuary, or benefit payments might be misclassified. Another frequent issue involves inconsistencies between operational practice and the plan document. If the way benefits are administered or contributions are handled deviates from what is formally stated in the plan's legal document, it creates a compliance risk that can surface during a Form 5500 audit. Regular reconciliation and robust internal controls are essential to mitigate these risks.

For larger plans, an independent qualified public accountant (IQPA) audit is often required as part of the Form 5500 filing. This audit extends to the 401(h) component, verifying the accuracy of financial statements, asset allocations, benefit payments, and statutory compliance. The auditor will review the segregated account's activity, ensuring it adheres to plan provisions and IRS regulations.

Furthermore, actuarial certifications play a vital role in validating the funding status of the 401(h) account. An enrolled actuary will certify that the contributions are sufficient to provide the promised medical benefits, that the actuarial assumptions are reasonable, and that contribution limits are respected. These certifications are critical supporting documents for the Form 5500 and provide assurance of the plan's long-term viability and compliance.
