How 401(h) Medical Benefits Work Inside Qualified Plans
A modern, professional, educational resource designed for trust, clarity, and strong consultation intent.
A 401(h) medical benefit is not a standalone retirement plan. It is a medical-benefit feature that can be built into a qualified pension or annuity plan to provide retiree medical benefits for eligible retired employees and, in many cases, their spouses and dependents, subject to plan terms and applicable rules.
For the right employer, this feature can support a broader retirement and post-retirement healthcare strategy. But it only works when the plan is designed carefully, funded properly, and administered in line with the special rules that apply to Section 401(h) arrangements.

For the right employer, this feature can support a broader retirement and post-retirement healthcare strategy. But it only works when the plan is designed carefully, funded properly, and administered in line with the special rules that apply to Section 401(h) arrangements.
What Is a 401(h) Benefit?
Section 401(h) allows a qualified pension or annuity plan to provide sickness, accident, hospitalization, and medical benefits for retired employees, their spouses, and their dependents.
That point matters because many employers assume a 401(h) account is a separate health plan. It is not. It exists only inside an otherwise qualified pension or annuity arrangement, which is why plan design and document language matter so much.
In plain English, a 401(h) feature gives an employer a way to set aside part of a qualified plan’s resources for retiree medical benefits rather than retirement income alone. That can make it worth evaluating for employers who want to address healthcare costs in retirement as part of a larger planning strategy.
How It Fits Inside a Qualified Plan
A 401(h) arrangement must be part of a qualified pension or annuity plan. It is commonly discussed in the defined benefit context because the medical-benefit piece sits inside the broader qualified plan structure rather than standing on its own.
An employee generally must be eligible for retirement benefits under the pension plan to receive 401(h) medical benefits, unless the employee retired because of permanent disability under the applicable rules.
That means employers are not simply adding a health reimbursement feature in isolation. They are working within a retirement-plan framework that carries its own eligibility, funding, documentation, and compliance obligations.
Who Can Receive Benefits
The core beneficiaries are retired employees. Coverage may also extend to spouses and dependents if the plan is written that way and the arrangement satisfies the governing requirements.
The benefits themselves can include medical-related costs such as sickness, accident, hospitalization, and other medical benefits described in the rules.
Recent IRS guidance also confirmed that retirees do not lose eligibility for 401(h) coverage simply because their pension benefits have been annuitized, which is an important practical point for plan sponsors evaluating long-term retiree health coverage design.
How the Separate Account Works
A separate account must be maintained for the 401(h) portion of the plan for recordkeeping purposes. That does not necessarily mean the assets must be invested in a completely separate pool, but the accounting for the medical-benefit feature has to be clear.
This is one of the most important operational points. If the employer cannot identify what has been contributed for 401(h) benefits and what liabilities those amounts support, the arrangement becomes harder to administer and defend.
The employer must also designate the portion of contributions allocated to the 401(h) medical-benefit funding. In other words, the plan cannot treat this as a vague side pocket; the funding allocation needs to be identified and documented.
How Funding Works
Funding a 401(h) arrangement is not as simple as deciding to contribute an extra amount whenever cash flow allows. Contributions for the medical-benefit portion must be reasonable and ascertainable under the rules.
There is also a key subordination rule. Medical benefits under 401(h), together with life insurance protection, must remain subordinate to the plan’s retirement benefits.
A commonly cited way this is tested is the 25 percent rule: aggregate contributions for 401(h) medical benefits and life insurance protection generally cannot exceed 25 percent of the aggregate contributions made after the feature is added, excluding contributions for past service credit.
That rule is one reason 401(h) planning is technical. Employers cannot simply maximize the medical-benefit side without considering the overall retirement plan, contribution history, and ongoing funding pattern.
Compliance Points Employers Should Understand
A 401(h) feature has to satisfy nondiscrimination requirements. It cannot favor officers, shareholders, supervisors, or highly compensated employees with respect to coverage, contributions, or benefits.
Plan assets set aside for 401(h) benefits also cannot be diverted to another purpose before liabilities for those medical benefits have been satisfied, other than appropriate administrative expenses.
The plan document should also address what happens if money remains in the 401(h) account after all liabilities have been satisfied, including the applicable reversion rules. That is not a drafting footnote; it is part of the structure that makes the arrangement workable and compliant.
This is why 401(h) design is not just about tax efficiency. It is also about recordkeeping, actuarial coordination, plan language, and long-range administration.
Where This Feature May Fit
A 401(h) feature may be worth evaluating for employers that already use, or are considering, a qualified pension structure and want to address retiree medical costs in a more deliberate way. That can include professional practices, closely held businesses, and other successful employers trying to coordinate tax planning, retirement benefits, and post-retirement healthcare strategy.
It may be especially relevant when the employer wants a more integrated approach rather than treating healthcare costs in retirement as a separate problem to solve later. In the right situation, a 401(h) feature can complement a broader retirement-plan design rather than compete with it.
It will not be the right fit for every business. Cash flow, workforce demographics, administrative complexity, and long-term commitment all matter, and the arrangement should be evaluated with qualified professionals before implementation.
A Simple Example
Consider a profitable medical or dental practice that already values long-term retirement planning and wants to think more strategically about retiree healthcare costs. Instead of looking only at retirement income design, the owners may evaluate whether a defined benefit structure with a 401(h) feature could support both retirement objectives and future medical-benefit planning.
The answer would depend on the plan’s design, the owner group, employee demographics, funding goals, and the compliance rules described above. But it shows why this is not just a technical pension topic. It can become part of a broader planning conversation for employers who want more than a basic off-the-shelf arrangement.
Why Advisors Should Understand It
For CPAs, EAs, tax preparers, and retirement advisors, 401(h) is one of those provisions that can easily be overlooked even though it may create a meaningful planning discussion in the right fact pattern. The value is not in forcing the strategy onto every client. The value is in recognizing when a client’s retirement plan, tax profile, and retiree medical goals may justify a closer look.
That is also where coordination matters. Retirement Actuarial Services positions its work around advanced retirement planning, tax-aware strategy, and collaboration with tax advisors, which makes this topic highly relevant for firms that serve business-owner clients and want practical implementation support rather than theory alone.

The rules describe sickness, accident, hospitalization, and medical benefits for retired employees and eligible family members.
It means the medical-benefit feature cannot overshadow the plan’s retirement purpose. A common way this is tested is the rule that aggregate contributions for 401(h) medical benefits and life insurance generally cannot exceed 25 percent of aggregate post-adoption contributions, excluding past service credit contributions.
Yes. A separate account must be maintained for the 401(h) portion for recordkeeping purposes, even if the assets are not maintained in a separately invested trust sleeve.
