Employers committed to supporting their retirees with long-term healthcare funding often turn to 401(h) accounts. These sub-accounts, part of a qualified pension or profit-sharing plan, provide a structured and tax-efficient mechanism for covering post-retirement medical expenses. Yet, with this benefit comes a complex and highly regulated environment that employers must navigate carefully.

At Full Focus Financial, we help businesses understand and comply with the intricate 401h Plans Legal and Regulatory requirements. These plans represent more than a financial vehicle—they are a reflection of a company’s commitment to its workforce and must be structured with utmost precision to preserve both tax advantages and regulatory standing.
The Structure and Purpose of a 401(h) Plan
A 401(h) account operates as a medical benefit funding vehicle within an existing qualified plan, such as a defined benefit pension or money purchase plan. It allows employers to fund retiree healthcare on a tax-deferred basis, with the following benefits:
- Tax-deductible contributions
- Tax-free withdrawals for qualified healthcare expenses
- Tax-deferred investment growth
But to realize these benefits and protect the integrity of the retirement plan, employers must stay within the boundaries of federal law.
The Governing Bodies and Laws Behind 401(h) Accounts
Multiple regulatory authorities and statutes oversee the legality and administration of 401(h) plans. Employers must comply with all of them to maintain qualified plan status:
Internal Revenue Service (IRS)
The IRS is the primary authority on the tax treatment of 401(h) contributions and distributions. Section 401(h) of the Internal Revenue Code lays out specific contribution and funding requirements.
Employee Retirement Income Security Act (ERISA)
ERISA governs fiduciary standards, reporting, and disclosures. Employers must operate the 401(h) component in line with ERISA’s requirements to protect participants and avoid fiduciary breaches.
Department of Labor (DOL)
The DOL ensures employers fulfill their ERISA obligations, particularly in reporting, disclosure, and fiduciary accountability.
HIPAA and State Insurance Laws
Since 401(h) accounts are used for retiree healthcare, HIPAA privacy rules may apply when handling personal health information. Some state laws may also affect how medical benefits are delivered or funded.
Legal Requirements for 401(h) Compliance
To ensure legal integrity and maintain tax-qualified status, a 401(h) account must meet specific structural and operational standards.
1. Subordinate Account Status
The 401(h) account must always remain subordinate to the main retirement benefit. It cannot exceed a certain threshold of total contributions, ensuring the focus remains on retirement income.
2. 25% Contribution Limitation
Perhaps the most well-known rule: total contributions to the 401(h) cannot exceed 25% of the aggregate employer contributions to the main retirement plan. This is not an annual cap, but a cumulative limit over time—requiring rigorous tracking and record-keeping.
3. Segregated Accounting
Employers must maintain entirely separate accounting for the 401(h) portion of the plan. These assets cannot be co-mingled with general plan funds and must be used solely for retiree healthcare.
4. Non-Reversion of Funds
Funds in the 401(h) cannot revert to the employer, under any condition. They are exclusively for the benefit of plan participants, their spouses, and eligible dependents.
5. Nondiscrimination Testing
401(h) benefits must not disproportionately favor highly compensated employees. Employers must perform nondiscrimination testing annually and adjust benefits or eligibility criteria accordingly.
6. Reporting and Disclosure
Employers must include 401(h)-related financials in their Form 5500 filings and provide comprehensive participant disclosures via Summary Plan Descriptions (SPDs) and any applicable Summary of Material Modifications (SMMs).
The Consequences of Non-Compliance
The legal consequences of non-compliance can be severe, and they often extend beyond the 401(h) sub-account:
- Plan Disqualification: Violating IRS regulations may cause the entire pension plan to lose its tax-qualified status.
- Excise Taxes: Excess contributions or prohibited uses of 401(h) assets can trigger significant IRS penalties.
- Fiduciary Liability: ERISA violations may expose fiduciaries to personal liability and civil penalties.
- Tax Losses: Contributions may become non-deductible, and distributions could lose their tax-free status.
- Reputational Harm: Regulatory failures can lead to audits, public scrutiny, and diminished employee trust.
Real-World Compliance in Action
