The Triple-Tax Advantage for Health Costs in Retirement: How Business Owners Can Harness IRC §401(h)
Most business owners rely on standard Health Savings Accounts or post-tax withdrawals to prepare for medical costs late in life. However, IRC §401(h) provides a far more substantial path by allowing you to pre-fund retiree healthcare inside a qualified pension or defined benefit plan using tax-deductible dollars.
What the law actually says
Under IRC §401(h), a pension or annuity plan can provide medical benefits for retired employees, spouses, and dependents provided the structure meets five statutory requirements.
Subordinate Benefit Rule
Medical contributions cannot exceed 25% of total plan contributions made after the §401(h) feature is adopted.
Separate Accounting
§401(h) contributions must be tracked separately from the plan’s pension liabilities, even if assets are pooled for investment.
Exclusive Medical Use
§401(h) funds must be used only for eligible medical benefits and cannot be diverted to other plan purposes.
Reasonable & Ascertainable Coverage
Contributions must be actuarially determined to reasonably and necessarily fund future medical liabilities.
Mandatory Reversion
Once all medical liabilities are satisfied, any remaining balance reverts to the employer, rather than being distributed to employees.
Why It Matters for Business Owners
For business owners with substantial earnings, traditional pension and cash balance plans can provide significant upfront tax savings. However, standard retirement distributions are ultimately taxed as ordinary income. A §401(h) sub-account creates a separate tax-advantaged way to fund qualified healthcare costs in retirement.
Entity Benefit
Immediate Entity Deduction
Employer contributions to a §401(h) account are deductible under IRC §404(a), creating an immediate tax benefit for the business.
Growth
Tax-Free Growth
Assets in the §401(h) sub-account can grow without current federal or state income taxation while held within the plan trust.
Retirement
Tax-Free Medical Reimbursements
Qualified medical expenses paid from the account can be excluded from gross income, including eligible Medicare premiums, long-term care insurance premiums, and out-of-pocket medical costs.
Strategy in action
Consider a 55-year-old business owner earning consistent annual profits who operates an active Cash Balance Plan alongside a profit-sharing structure.
1
Funding Phase
The business amends its plan to add a §401(h) sub-account. The owner contributes $200,000 to the plan for the year, directing $40,000 (20%) into the §401(h) sub-account—comfortably below the 25% limit. The full $200,000 deduction lowers corporate taxable income immediately.
2
Growth Phase
Over 10 years, the $40,000 annual medical allocation grows tax-free within the plan trust, accumulating to roughly $550,000 by age 65.
3
Distribution Phase
At age 65, the owner retires and draws $30,000 per year from the §401(h) account to pay for Medicare Part B/D, long-term care insurance, and out-of-pocket medical costs. Because these reimbursements are non-taxable, the owner pays $0 in income tax on these distributions.
Common Misconceptions and Structural Pitfalls
Misconception 1
Reality
"It acts like a rollover HSA."
False. If an employee leaves before reaching retirement age, non-vested §401(h) assets do not move with them; they stay in the trust to fund future medical costs or reduce future employer contributions.
Misconception 2
Reality
"You can add money after you retire."
False. Contributions must occur during active employment service. Funding stops once you retire.
Misconception 3
Reality
"Unused funds can roll into an IRA."
False. §401(h) balances cannot roll into individual retirement accounts; remaining funds revert to the company as taxable income upon plan termination.
How ClairFi Thinks About This
At ClairFi, we treat health costs and portfolio strategies as combined balance sheet decisions. The §401(h) sub-account is an overlay for businesses utilizing or adding Defined Benefit or Cash Balance structures.
Because it involves actuarial calculations and annual Form 5500 filings, proper setup requires coordination between tax advisors, plan administrators, and ERISA counsel.
Key Takeaways
Triple-Tax Savings
Delivers tax deductions today, tax-free accumulation, and tax-free distributions for health expenses in retirement.
Cap Limits
Medical funding cannot exceed 25% of total plan contributions made after adopting the feature.
Ideal Fit
Built for business owners aged 50–65 with strong cash flow who use cash balance or pension plans.
Strict Allocation
Funds must cover IRC §213(d) health expenses; unused balances revert to the business, not the owner personally.
Tax Advantaged Retiree Healthcare Planning Under IRC §401(h)
The cost of healthcare in retirement represents one of the largest unmitigated liabilities for high-earning professionals and business owners. While standard planning relies heavily on Health Savings Accounts (HSAs) or post-tax distributions, Internal Revenue Code (IRC) §401(h) permits a far more powerful mechanism. By embedding a specialized medical reimbursement sub-account within a qualified pension or defined benefit plan, business owners can pre-fund retiree healthcare using deductible corporate dollars, accumulate investment growth tax-free, and execute tax-free distributions for qualified medical expenses.
What the law actually says
Under IRC §401(h), a pension or annuity plan may provide for the payment of benefits for sickness, accident, hospitalization, and medical expenses of retired employees, their spouses, and their dependents.
Subordinate Benefit Rule
Medical benefits must remain subordinate to retirement benefits, with contributions limited to 25% of total plan contributions.
Separate Accounting
§401(h) contributions must be tracked separately from pension liabilities, even when assets are pooled for investment.
Impossibility of Diversion
§401(h) funds must be used exclusively for medical benefits until all liabilities are satisfied.
Reasonable & Ascertainable Coverage
Contributions must be actuarially determined to be reasonable and necessary to cover future medical liabilities under the plan.
Mandatory Reversion
Once all retiree medical liabilities are satisfied, any remaining balance must revert to the employer and cannot be distributed to employees as retirement income.
Why It Matters for High Earners and Business Owners
For high-income professionals and closely held business owners, tax planning often focuses on maximizing qualified retirement plan contributions. While traditional defined benefit and cash balance distributions are taxable in retirement, a §401(h) sub-account can provide a tax-advantaged way to fund qualified healthcare costs.
Contribution
Deduction at the Entity Level
Employer contributions to a §401(h) account are fully deductible under IRC §404(a) as ordinary and necessary business expenses.
Growth
Tax-Free Compounding
Assets in the §401(h) sub-account grow free of federal and state income tax while held in trust.
Distribution
Tax-Free Extraction
Qualified medical reimbursements under IRC §213(d) are excluded from gross income, including eligible Medicare, Medigap, long-term care, and out-of-pocket medical costs.
Strategy in Action: A Case Scenario
Consider a closely held enterprise where the owner is 55, generates strong predictable cash flow, and maintains an active Cash Balance Plan alongside a qualified profit-sharing plan.
1
Funding Phase
The company adds a §401(h) retiree medical account. It contributes $200,000 annually, with $40,000 (20%) allocated to the §401(h) sub-account—within the 25% limit. The full contribution reduces the business’s taxable income for the year.
→
Tax Result:Tax Result: The full $200,000 contribution reduces the business's taxable income for the year. At a combined top marginal rate, this yields immediate tax savings on the operational profit.
2
Growth Phase
Over 10 years, the $40,000 annual §401(h) allocations are invested within the plan trust and compound tax-free, growing to approximately $550,000 by age 65.
3
Distribution Phase
At age 65, the owner begins using the §401(h) account to reimburse qualified healthcare costs, including long-term care insurance premiums and out-of-pocket medical expenses.
→
Tax Result:Tax Result: The owner receives $30,000 per year in medical reimbursements tax-free. Unlike distributions from standard IRAs or defined benefit allocations, these distributions do not increase adjusted gross income (AGI), preventing higher Medicare Part B/D surcharges (IRMAA) and eliminating income tax liability on those funds.
Common Misconceptions and Structural Pitfalls
Misconception 1
Reality
"A 401(h) operates just like a rollover HSA."
Unlike an HSA, §401(h) funds are tied to a qualified pension plan. Non-vested balances may be forfeited upon separation and remain in the plan trust.
Misconception 2
Reality
"You can fund a 401(h) after you retire."
§401(h) contributions must be made before retirement. Once retired, funding stops and the account enters its payout phase.
Misconception 3
Reality
"Unused funds can be rolled into an IRA at plan termination."
§401(h) funds cannot be rolled into an IRA or 401(k). Any remaining balance after plan termination reverts to the employer as taxable income.
How ClairFi Thinks About This
At ClairFi, we treat health capital and investment capital as interconnected balance sheet items. The §401(h) provision is not a standalone product; it is an advanced structural overlay for businesses that already have, or are candidates for, Defined Benefit or Cash Balance pension structures.
Because of the mandatory actuarial calculations, 25% subordination cap testing, and annual Form 5500 compliance reporting, implementing IRC §401(h) requires tight integration between third-party administrators (TPAs), ERISA attorneys, and tax advisors. When executed correctly, it serves as one of the few remaining mechanisms to achieve triple-tax advantages on large-scale capital.
Key Takeaways
Triple-Tax Structure
Delivers tax-deductible contributions, tax-deferred growth, and tax-free distributions for qualified retiree healthcare costs.
Subordinate Limit
Funding for the 401(h) feature cannot exceed 25% of total aggregate plan contributions made after the feature is adopted.
Entity Fit
Ideal for established business owners and high-income professionals aged 50–65 with high profits who utilize Defined Benefit or Cash Balance structures.
Strict Usage
Funds must reimburse valid IRC §213(d) expenses; unspent balances upon plan termination revert to the business entity, not the individual.
