401(h) Account Funding Strategies: How Money Gets In
Funding a 401(h) is an actuarial decision, not a number you pick. Here are the strategies that drive how money flows into the sub-account over time.
Contents
Key takeaways
- Funding flows from the actuarial valuation, not from a flat contribution form.
- The incidental-benefit rule caps medical funding relative to retirement funding.
- Sponsor cash-flow profile drives the choice between level and accelerated funding.
- Demographics — especially retiree class age — materially affect the funding number.
Start from the projected benefit
Funding starts with the projected stream of retiree medical benefits the plan promises. That stream is converted into a present-value funding requirement using the plan's actuarial assumptions — return, mortality, medical-cost trend, and turnover.
Level vs accelerated funding
Sponsors with stable cash flow often prefer level funding spread across the working lives of the eligible class. Sponsors with episodic profits sometimes use front-loaded strategies — within the incidental-benefit ceiling — to lock in deduction value during high-income years.
Coordination with the underlying plan
401(h) contributions sit alongside the retirement-benefit contributions. The actuary models both streams together to ensure the incidental-benefit ratio holds across plan years.
Risks to model
Funding strategy is sensitive to:
- Medical-cost trend assumption changes.
- Retiree-class demographic shifts.
- Investment performance vs assumed return.
- Sponsor cash-flow disruption.
