In today’s increasingly complex benefits environment, offering retiree medical benefits through a 401(h) plan is not just a generous gesture—it’s a strategic advantage. However, employers considering or administering a 401(h) sub-account must be fully versed in its intricate legal and regulatory framework. Missteps in compliance can jeopardize the tax-qualified status of the entire retirement plan and expose the business to financial penalties and fiduciary risks.
At Wittrock Financial Group, we believe employers deserve expert guidance in navigating these complexities. This comprehensive guide explains the 401h Plans Legal and Regulatory landscape and illustrates how meticulous plan design and administration can both safeguard compliance and deliver substantial long-term value.
What Is a 401(h) Plan?
A 401(h) plan is a retiree medical benefits account established within a defined benefit or money purchase pension plan. Contributions made to this sub-account are used exclusively to pay for post-retirement healthcare expenses. Because these contributions receive favorable tax treatment, the IRS places significant restrictions on their use and administration.
Key benefits of a 401(h) account include:
- Tax-deductible employer contributions
- Tax-free earnings on plan assets
- Tax-free distributions for qualifying medical expenses
But these benefits are contingent on strict compliance with IRS rules, ERISA fiduciary standards, and associated federal regulations.
The Legal Foundation of 401(h) Plans
401(h) plans derive their authority from multiple federal laws and regulatory bodies. Understanding these sources of law is crucial for compliance.
1. Internal Revenue Code (IRC) – Section 401(h)
The IRS governs how 401(h) accounts are structured and funded. Employers must follow rules such as:
- Funds can only be used for reasonable and necessary retiree medical expenses.
- Contributions must be subordinate to pension benefits.
- 401(h) contributions must not exceed 25% of the total contributions to the pension plan.
These rules are non-negotiable and form the core of legal compliance.
2. Employee Retirement Income Security Act (ERISA)
ERISA sets fiduciary standards for managing retirement and health benefits. Fiduciaries must:
- Act in the exclusive interest of participants,
- Avoid conflicts of interest,
- Follow the plan document, and
- Provide disclosures via Form 5500 and Summary Plan Descriptions (SPDs).
ERISA violations can result in civil penalties and personal liability.
3. Health Insurance Portability and Accountability Act (HIPAA)
Because 401(h) plans handle health information, employers must ensure compliance with HIPAA privacy and security provisions.
4. Department of Labor (DOL) Regulations
The DOL enforces ERISA and supplements it with interpretative guidance on fiduciary duties, benefit disclosures, and plan operations.
Core 401h Plans Legal and Regulatory Requirements
Let’s explore the key mandates every employer must satisfy to maintain a compliant 401(h) plan:
A. Contribution Limits (25% Rule)
The 401(h) sub-account must not receive contributions exceeding 25% of total cumulative contributions to the pension plan. This limit is cumulative—not annual—and must be tracked meticulously. Exceeding this cap could trigger IRS excise taxes and risk plan disqualification.
B. Subordinate Account Status
The 401(h) account must remain clearly secondary to the primary retirement benefit. It cannot overshadow or replace the core retirement component.
C. Exclusive Benefit Use
Funds must be used only for post-retirement medical care—including for retirees, spouses, and dependents. Any diversion of assets for other purposes is a serious compliance breach.
D. Separate Accounting
Assets allocated to the 401(h) plan must be segregated and tracked independently from pension funds. Failure to maintain accurate, distinct records may lead to audit findings and tax penalties.
E. Nondiscrimination Testing
Benefits must not disproportionately favor highly compensated employees. Employers must conduct annual testing to confirm compliance.
F. Reporting and Disclosure
401(h) plans must be disclosed in the pension plan’s Form 5500 filings. Participants must receive SPDs and Summary of Material Modifications (SMMs) detailing the medical benefit component.
What Happens When Employers Get It Wrong?
The risks associated with non-compliance are substantial and can severely impact both the plan and the organization:
- Plan Disqualification: A violation in the 401(h) account can disqualify the entire pension plan, resulting in retroactive taxation of contributions and distributions.
- Excise Taxes: The IRS may levy excise taxes for excess contributions or misuse of funds.
- Fiduciary Liability: ERISA fiduciaries can be held personally liable for losses due to non-compliance.
- Reputational Harm: Compliance failures can undermine employee trust and attract regulatory scrutiny.
