As retirees face rising healthcare costs, many employers seek ways to offer stronger support beyond basic Medicare. That’s where 401(h) plans come in—offering a powerful, tax-advantaged tool to pre-fund retiree medical expenses. But how do 401(h) plans and Medicare work together? When properly coordinated, they provide a stronger safety net for retirees and a smarter funding strategy for employers.
What Are 401(h) Plans and Medicare?
The Role of a 401(h) Plan
A 401(h) plan is a special medical account established under a defined benefit pension or 401(a) plan. Its primary purpose is to cover post-retirement medical expenses with tax advantages:
- Tax-Free Growth: Employer contributions are tax-deductible, assets grow tax-free, and distributions for qualified medical costs are also tax-free.
- Pre-Funding Strategy: It allows employers to proactively fund long-term retiree healthcare liabilities.
- IRS Subordination Rule: Contributions to the 401(h) account must not exceed 25% of total contributions to the base plan.
Medicare Basics
Medicare is a federal insurance program for people aged 65+, younger individuals with disabilities, and those with End-Stage Renal Disease (ESRD). It has four key parts:
- Part A: Covers hospital and inpatient care.
- Part B: Covers outpatient services and doctor visits.
- Part C: Also called Medicare Advantage, includes A, B, and often D.
- Part D: Covers prescription drugs.
How 401(h) Plans and Medicare Work Together
When retirees qualify for Medicare, the 401(h) plan typically becomes a secondary payer, covering expenses that Medicare does not fully pay.
Understanding Payer Order
| Situation | Primary Payer | Secondary Payer |
|---|---|---|
| Retired, Age 65+ | Medicare | 401(h) Plan |
| Retired, Under 65 | 401(h) Plan | N/A |
| Working, Age 65+ with GHP | Group Plan | Medicare / 401(h) Plan |
Covered Expenses After Medicare Eligibility
- Premiums for Medicare Parts A (if applicable), B, C, and D
