The HSA is the only triple-tax-advantaged account in the U.S. tax code — deductible going in, tax-free growing, tax-free coming out for medical. Most people use it like a flexible spending account and miss the point entirely.
Real-world scenario
35-year-old maxes HSA for 25 years, invests it instead of spending
She contributes $4,300/year (self-only, 2025 limit), invests in low-cost index funds, and pays current medical bills out-of-pocket while saving receipts. At a 7% real return over 25 years, the HSA grows to ~$285,000 — every dollar tax-free for medical. At retirement, she reimburses herself for 25 years of saved receipts, completely tax-free.
The part most people miss
After 65, HSA withdrawals for any purpose are taxed like a traditional IRA — no 20% penalty. Combined with the medical-reimbursement-anytime rule, the HSA effectively becomes a better Traditional IRA. Almost no one treats it that way; they swipe the debit card at CVS and lose decades of tax-free growth.
