How the Calculation Works

HSA (Health Savings Account) is the only US tax-advantaged account with TRIPLE tax benefit: (1) pre-tax contribution (reduces W-2 wages), (2) tax-free growth (no capital gains, no dividends tax), (3) tax-free withdrawal for qualified medical expenses. Strategy: invest contributions, pay current medical expenses out-of-pocket, save receipts, withdraw decades later tax-free.

Benchmarks and Use Cases

2026 HSA limits: $4,400 self-only HDHP, $8,750 family HDHP. Catch-up $1,000 at 55+. Eligible if covered by HDHP (min deductible $1,650 single / $3,300 family, max OOP $8,300 / $16,600). HSA stays with you across jobs and rolls forever. At 65+, withdrawals for non-medical purposes treated like IRA (taxable but no penalty).

Common Mistakes and Limitations

Common mistakes: (1) Using HSA for current medical bills instead of investing. (2) Choosing non-investment HSA (HealthEquity charges $3/mo until $1k, Fidelity HSA is free with full Vanguard fund access). (3) Failing to save medical receipts — IRS allows withdrawal years later for past unreimbursed medical with documentation. (4) Skipping the catch-up contribution at 55+.
