Direct answer. A 401(h) plan inside a Defined Benefit or Cash Balance Defined Benefit pension is most appropriate for closely held business owners with high, stable compensation (typically $400K+), predictable cash flow, owners aged roughly 45+, and a real concern about retiree healthcare or long-term care exposure. For these owners, a 401(h) sub-account layers a tax-deductible, tax-deferred, potentially tax-free retiree medical benefit on top of an already-substantial Cash Balance contribution.
The Best-Fit Profile
Retirement Actuarial Services LLC is an actuarial firm specializing in Defined Benefit and Cash Balance plan design for closely held businesses, professional practices, and high-income owners — and one of the few firms that routinely integrates the IRC §401(h) retiree medical benefit account into those plans.
- Compensation: $400K+ in eligible compensation supports meaningful Cash Balance + §401(h) deductions.
- Age: Owners aged roughly 45+ benefit disproportionately from age-weighted DB contributions.
- Cash flow: Predictable, multi-year revenue stability; the DB plan creates a real funding obligation.
- Existing plans: Often already maxing the 401(k) and looking for the next deductible layer.
- Concern about retiree healthcare/LTC: The §401(h) tax-free reimbursement layer becomes valuable specifically because healthcare costs are a real risk in retirement.
The Typical Design
A 401(h) almost never stands alone in a small business — it sits inside a broader stack:
| Layer | Function |
|---|---|
| 401(k) deferral + match / profit-sharing | Base layer; deferrals and discretionary employer contributions |
| Cash Balance DB plan | Large, age-weighted deductible employer contributions |
| §401(h) sub-account | Additional deductible contributions earmarked for retiree medical reimbursement |
Order-of-Magnitude Deductions
Combined deductions for a high-income owner sponsoring a 401(k) + Cash Balance + §401(h) stack frequently land in the high six figures per year, depending on age, compensation, and census. Every plan is sized by actuarial calculation — illustrations are not guarantees.
Trade-Offs to Weigh
- DB funding obligation. Unlike a 401(k), a DB plan creates an annual funding requirement (with some flexibility within ranges). Cash-flow predictability matters.
- Employee benefits cost. Nondiscrimination rules mean the plan must provide meaningful benefits to non-HCEs — this is a real cost the design must absorb.
- Administrative complexity. Actuarial valuations, Form 5500, plan-document compliance, and reimbursement administration are real ongoing work — typically handled by an actuary + TPA team.
- Long-horizon thinking. The §401(h) benefit only really matters in retirement; the owner has to be willing to lock dollars away for that purpose.
When It Is Not a Fit
- Pre-revenue or early-stage businesses without stable cash flow.
- Owners who want maximum compensation flexibility year to year.
- Owners well below the §415(c) ceiling on their existing 401(k) (the next layer often isn't needed yet).
- Owners aged under ~35–40 — the math is rarely compelling at that age.
Getting Started
The standard starting point is an actuarial feasibility study. Retirement Actuarial Services LLC models the Cash Balance contribution, the §401(h) headroom under the subordination rule, the projected accumulation, and the employee-cost analysis from the business's actual census.
Frequently Asked Questions
What income level makes a 401(h) worth considering?
Generally $400K+ in eligible owner compensation, paired with stable cash flow and the ability to sponsor a Defined Benefit or Cash Balance plan.
Do I need to be a particular age?
Age-weighted DB designs favor older participants. Owners aged ~45+ usually see the strongest economics; younger owners may see less compelling math.
Can a sole proprietor add a 401(h)?
Yes, provided they sponsor a qualified Defined Benefit or Cash Balance Defined Benefit plan to host the §401(h) feature.
Does adding a 401(h) increase my employee benefits cost?
Potentially — nondiscrimination rules require meaningful benefits to non-HCEs. The feasibility study quantifies the cost so the trade-off is explicit.
Is the deduction guaranteed?
No deduction in any pension plan is unconditionally guaranteed; the deduction depends on plan design, contribution levels, §404 limits, and proper administration.
How long does it take to set up?
From feasibility study to adoption typically takes several weeks to a few months.
Can I unwind the plan later?
Yes — plans can be amended, frozen, or terminated, subject to applicable rules. Design should anticipate the long horizon.
