How 401(h) Medical Benefits Work
Inside Qualified Plans
A practical resource for employers, plan sponsors, CPAs, and advisors exploring retiree medical benefit design inside qualified pension structures.
Introduction
Retiree healthcare costs can put real pressure on employers and business owners, especially when traditional plan design no longer feels flexible enough. A 401(h) arrangement is one way a qualified pension or annuity plan may provide medical benefits for retired employees, their spouses, and their dependents, provided the plan satisfies specific tax-qualification rules.
In plain English, a 401(h) account is a retiree medical benefit feature housed inside a qualified pension structure, not a standalone health plan and not a standard 401(k). It is commonly used in discussions about employer-sponsored retiree health benefits because it can help carve out a dedicated pool for qualified post-retirement medical expenses, subject to plan design, contribution limits, and compliance requirements.
For employers, plan sponsors, CPAs, and advisors, the key point is simple: 401(h) medical benefits can be powerful when they are designed carefully, documented properly, and coordinated with the rest of the retirement plan. Advanced planning materials in this space often evaluate 401(h) alongside broader retirement and tax-efficiency strategies for the right business-owner profile, but the medical feature still has to stand on its own legal and actuarial footing.
What Is a 401(h) Account?
A 401(h) account is a separate medical-benefit account maintained within a qualified pension or annuity plan. The governing rules allow that plan to pay benefits for sickness, accident, hospitalization, and medical expenses for retired employees, their spouses, and their dependents.
That "inside the plan" point matters. A 401(h) feature is not the same thing as a 401(k), and the IRS training material specifically notes that a 401(h) account is not permitted inside a profit-sharing plan, even though profit-sharing and 401(k) arrangements may be part of a broader coordinated strategy outside the 401(h) feature itself.
To qualify, the plan has to do more than mention retiree medical benefits. The regulations require the plan to specify the medical benefits that will be available and contain provisions for determining the amount that will be paid. The rules also require a separate account for recordkeeping, even though the assets do not have to be separately invested if earnings are allocated reasonably.
Eligibility is narrower than many people expect. Under the regulations, 401(h) medical benefits may be provided only for retired employees, their spouses, or their dependents, and an employee generally must be eligible for retirement benefits under the pension plan or be retired because of permanent disability.
How This Differs from More Familiar Options
| Feature | Description |
|---|---|
| Standard 401(k) | A defined contribution retirement arrangement. |
| 401(h) Account | A medical-benefit component that sits inside a qualified pension or annuity plan and is governed by separate qualification rules. |
| HSA | Individual accounts tied to high-deductible health plan eligibility, while a 401(h) arrangement is employer plan design inside a qualified retirement framework for retiree medical benefits. |
This page focuses on the 401(h) structure, because the design issues, funding rules, and compliance concerns are not the same.
How 401(h) Medical Benefits Work
At a practical level, the employer sets up a qualified pension plan document that includes a properly drafted 401(h) feature. The plan then maintains a separate account for the retiree medical portion, and contributions allocated to that account are intended to fund qualifying medical benefits under the terms of the plan.
The regulations allow contributions for 401(h) medical benefits on either a contributory or noncontributory basis. In other words, the medical portion may be funded entirely by employer contributions even if the retirement portion of the plan uses a different contribution structure.
Just as important, the money is restricted. Before all medical liabilities are satisfied, it must be impossible for the medical-benefit account to be used or diverted for purposes other than providing those medical benefits, aside from necessary administrative expenses attributable to the account.
The plan also has to respect the "subordinate" nature of the medical feature. The regulations and IRS guidance treat 401(h) medical benefits as ancillary to the retirement benefits, and the aggregate contributions for medical benefits, together with life insurance protection under the plan, generally cannot exceed 25 percent of aggregate contributions after the account is established, excluding contributions for past service credits.
That 25 percent test is a major design issue because it is cumulative, not just a one-year snapshot. The IRS training material explains that the subordination test looks at aggregate actual contributions made after the date the 401(h) account is established, which means timing, amendment dates, and contribution history matter.
Real-World Planning Scenario
Consider a successful professional services firm with $800,000 in annual owner income, stable revenue, and a desire to reduce current tax burden while building retiree healthcare reserves. The owner already sponsors a cash balance defined benefit plan and is exploring whether adding a 401(h) medical benefit feature makes sense.
The Planning Issue
Traditional 401(k) contributions are maxed out, and the owner wants to address both retirement income and future medical expenses in a tax-efficient way.
The 401(h) Consideration
If the firm's pension plan is amended to include a properly drafted 401(h) feature, a portion of the overall contribution can be allocated to a separate medical-benefit account. That account could potentially fund qualified retiree medical expenses down the road, but the design must satisfy the subordination test (generally limiting medical contributions to 25% of aggregate plan contributions), maintain separate accounting, specify covered benefits, and meet all nondiscrimination requirements.
The Outcome
After actuarial modeling and feasibility review, the firm determines that a coordinated approach using the pension plan with a 401(h) feature fits their long-term goals, cash flow capacity, and compliance readiness. A different firm with inconsistent revenue or simpler plan objectives might conclude that the administrative complexity outweighs the benefit.
Key Rules, Limitations, and Compliance Considerations
Several compliance points deserve close attention.
Core Requirements
Benefits must be for retired employees, their spouses, and their dependents, with retirement-status rules defined by the regulations.
A separate account must be established and maintained for the medical-benefit portion.
The plan must specify the medical benefits available and how the amount paid will be determined.
Medical benefits must remain subordinate to retirement benefits, with the contribution test generally measured against the 25 percent aggregate threshold.
Assets in the medical account cannot be diverted to another purpose before all medical liabilities are satisfied.
After all liabilities tied to the medical-benefit portion are satisfied, remaining amounts in that separate account must revert to the employer under the terms of the plan.
Nondiscrimination and Key-Employee Issues
A plan providing 401(h) medical benefits cannot discriminate in favor of officers, shareholders, supervisory employees, or highly compensated employees with respect to coverage, contributions, or benefits, and the determination is made by looking at both the retirement and medical portions of the plan together. The rules also include special separate-account requirements for key employees when benefits are payable to them and their families.
Administrative Realities
This is not a "set it and forget it" design. The IRS training material emphasizes document review, amendment language, date-of-establishment issues, and operational consistency, all of which can affect whether the arrangement satisfies the qualification rules.
That matters because a 401(h) issue is not just a side feature. IRS guidance describes section 401(h) as a qualification provision, meaning a failure in form or operation can affect the qualified status of the broader pension plan and trust.
Potential Advantages for Employers and Participants
When the design fits, employers may see several practical benefits:
- 1A dedicated structure for retiree medical benefits inside a qualified pension framework.
- 2A way to prefund retiree medical obligations rather than relying purely on pay-as-you-go treatment, which the IRS training material contrasts with unfunded approaches outside a trust.
- 3Better strategic coordination with broader retirement and tax planning for some high-income business owners, especially in designs where actuarial modeling and multi-year planning discipline are already part of the conversation.
For participants, the appeal is usually simpler: more intentional planning around healthcare costs in retirement. For employers and advisors, the appeal is usually strategic: aligning retirement funding, tax-sensitive planning, and retiree benefit design in a more deliberate way.
When This Strategy May Be Worth Exploring
A 401(h) strategy is often worth a closer look when an employer already sponsors, or is open to sponsoring, a pension-based design and wants to think more seriously about retiree medical funding. It can also make sense when the business has stable cash flow, a long-term planning mindset, and a leadership team willing to handle the extra design and compliance work.
Good-Fit Indicators
- Annual business income typically above $300,000, with stable or predictable cash flow
- Existing or planned defined benefit or cash balance pension plan
- Interest in prefunding retiree medical obligations rather than relying on out-of-pocket expenses in retirement
- Willingness to work with actuaries, CPAs, and plan administrators on ongoing compliance
- Multi-year planning discipline and commitment to structured retirement strategy
When It May Not Fit
- The employer wants the simplest possible retirement plan with minimal administrative burden
- Business revenue or cash flow is inconsistent year to year
- The organization is not prepared for the documentation, separate accounting, and monitoring required
- No existing pension plan structure and no interest in sponsoring one
Because the subordination rules, account structure, eligibility conditions, and nondiscrimination issues all matter, a feasibility review is usually the right starting point.
Employer Decision Checklist
Before moving forward, employers and advisors should ask:
- Do we have a qualified pension or annuity plan structure that could support a 401(h) feature?
- Are the intended covered individuals actually within the retiree, spouse, and dependent categories allowed under the rules?
- Can the plan satisfy the cumulative subordination test over time, not just this year?
- Has the plan document clearly defined the medical benefits, payment method, and coordination with any other benefit source?
- Are administration, recordkeeping, and actuarial support in place to keep the arrangement compliant?
Frequently Asked Questions
A 401(h) plan is not a separate standalone plan in the usual sense. It is a medical-benefit feature inside a qualified pension or annuity plan that may pay sickness, accident, hospitalization, and medical expenses for retired employees, their spouses, and their dependents if the statutory and regulatory requirements are met.
A 401(k) is a defined contribution retirement arrangement. A 401(h) account is a retiree medical-benefit account inside a qualified pension or annuity plan, with its own eligibility, funding, separate-account, and subordination rules.
Yes, that is the core purpose of the arrangement. The rules permit payment of medical benefits for retired employees, their spouses, and dependents, and the account must be used only for those benefits until all liabilities are satisfied.
Only retired employees, their spouses, and their dependents may receive these benefits under the regulation, subject to the plan's terms and the retirement-status rules.
Tax treatment depends on the specific benefit design, the type of expense, how reimbursements are structured, and the applicable tax rules in effect at the time. Because those details are fact-sensitive, employers and participants should not assume a result without plan-specific review.
No. A 401(h) feature is only available within a qualified pension or annuity plan structure, and the arrangement has to satisfy detailed qualification requirements on design and operation.
