The Health Savings Account (HSA) is arguably the best tax-advantaged account in the American financial system — better than a 401(k) or Roth IRA in certain ways — and it's consistently underutilized. The reason: it's attached to a high-deductible health plan (HDHP), which many people avoid out of misunderstanding.
The triple tax advantage
2026 HSA contribution limits
| Coverage type | 2026 limit |
|---|---|
| Individual (self-only HDHP) | $4,300 |
| Family HDHP coverage | $8,550 |
| 55+ catch-up contribution | +$1,000 |
The stealth retirement account strategy
Here's the power move: max your HSA, invest it in index funds, and don't use it for current medical expenses if you can afford to pay out of pocket. Save all your medical receipts. After 65, you can withdraw for any reason (paying ordinary income tax, like a traditional IRA). Before 65, you withdraw tax-free for medical expenses from any year — including past expenses you paid out of pocket and kept receipts for.
