Most 401(h) work boils down to three buckets: document, design, administer. This checklist helps advisors keep all three honest.

Key takeaways

  • Document the structure before debating the details.
  • Design the participant class deliberately.
  • Integrate actuarial work end-to-end.
  • Build an administration cadence that survives staff turnover.

Documentation

Confirm the underlying qualified plan exists and that the 401(h) provisions are explicit, complete, and current.

  • Plan amendment establishing the 401(h) sub-account.
  • Eligible participant class clearly defined.
  • Qualifying retiree medical benefits defined.
  • Funding, forfeiture, and reversion mechanics addressed.
  • Summary Plan Description updated.

Design

Make the structural choices before the spreadsheet choices.

  • Which retirees are covered, and on what eligibility terms?
  • Which medical benefits or premium categories are in scope?
  • How are spouses and dependents treated?
  • How does the design satisfy nondiscrimination?

Funding

Funding is actuarial and ongoing, not a moment-in-time deposit.

  • Unified actuarial valuation covering DB/CB and 401(h) streams.
  • Documented funding policy.
  • Incidental-benefit monitoring methodology.
  • Cash-flow review against business reality.

Administration

Set the cadence and document the procedures.

  • Annual valuation, Form 5500, and operational review.
  • Claims procedure and substantiation standards.
  • Vendor list with documented responsibilities.
  • Restatement calendar.
  • Participant communications cycle.

Frequently asked questions

Typically a lead partner or designated advisor, with named backups in operations. Single-point-of-failure ownership is itself a risk.
