A Health Savings Account (HSA) offers three unparalleled tax benefits: 1) Contributions are 100% tax-deductible (saving Federal, FICA 7.65%, and State taxes); 2) All investment growth, interest, and dividends compound 100% tax-free; and 3) Withdrawals for qualified medical expenses are completely tax-free at any age.
Once you turn 65, the 20% non-medical withdrawal penalty disappears entirely. You can withdraw funds for any reason (housing, travel, general living) penalty-free, taxed just like a Traditional IRA. For medical expenses, withdrawals remain 100% tax-free for life.
Savvy investors pay for current medical expenses out of pocket with a rewards credit card, save and scan the digital receipts, and let their entire HSA balance compound aggressively in stock index funds. Decades later in retirement, they can reimburse themselves tax-free for all accumulated historical medical receipts in a massive lump sum.
For 2026, the statutory contribution limit is projected at $4,300 for individual (self-only) coverage and $8,550 for family coverage. Individuals aged 55 and older can contribute an additional $1,000 catch-up contribution.
