How 401(h) Plans Can Help Fund Retiree Medical Expenses

Pre-funding retiree medical benefits brings discipline to one of retirement planning's biggest unknowns. Here's how 401(h) sub-accounts contribute to that picture.

Key takeaways

  • Retiree healthcare is one of the largest and least-predictable retirement costs.
  • 401(h) sub-accounts pre-fund a defined stream of retiree medical benefits.
  • What 401(h) can pay depends on plan terms and applicable law.
  • Funding is actuarial and ongoing — not a one-time deposit.

Why pre-funding matters

Retiree healthcare costs are one of the largest and most uncertain components of retirement planning. Pre-funding a defined portion through a structured benefit may reduce reliance on pay-as-you-go arrangements that depend on the sponsor's ongoing willingness — and ability — to pay.

What expenses may qualify

Qualified retiree medical expenses are defined by plan terms and applicable law, and frequently include:

  • Certain health insurance premiums for retirees, spouses, and dependents.
  • Qualifying out-of-pocket medical costs as defined in the plan.
  • Long-term care premiums and Medicare-related premiums where plan and law allow.

How money gets in

Employer contributions to the 401(h) sub-account are determined actuarially, tied to the plan's overall funding methodology and to the projected stream of medical benefits. The incidental-benefit rule constrains the ratio of medical-benefit funding to retirement-benefit funding over the life of the plan.

How money gets out

Once retirees become eligible, the 401(h) account pays defined medical benefits in accordance with the plan document. Recordkeepers typically administer claim review and reimbursement processes consistent with the plan's stated procedures.

What it does not do

A 401(h) sub-account does not turn medical bills into deductible personal expenses for owners outside the plan structure, and it does not guarantee that all future retiree medical costs will be covered. It is a tool for formalizing and pre-funding a defined portion of a known liability, not a universal solution.

Frequently asked questions

No. The benefit is for retired employees, their spouses, and their qualifying dependents, as defined by the plan.
