Frequently Asked Questions
How much will my HSA grow to if I contribute $8,550/year?
$375,047 balance + $37,620 in tax savings. This assumes contributions are invested (not left in cash) at 7% average return over 20 years. The additional $37,620 in tax savings represents the deduction benefit at your 22% bracket.
What is the HSA triple tax advantage and how does it work?
(1) Contributions are pre-tax — reduces your taxable income by $8,550/year, saving $1,881 in federal tax annually. (2) Growth is tax-free — no capital gains or dividend tax while invested. (3) Withdrawals are tax-free for qualified medical expenses. No other account has all three benefits.
Should I invest my HSA or keep it in cash for medical expenses?
Invest and pay medical out-of-pocket now if you can afford it. Your HSA investment grows tax-free, and there's no time limit on reimbursing yourself — save receipts for years of medical expenses and reimburse yourself later when the balance is larger. This turns your HSA into a stealth retirement account.
Can I use HSA funds for non-medical expenses?
After age 65, yes — withdraw for any reason and pay ordinary income tax (same as a Traditional IRA). Before 65, non-medical withdrawals incur income tax plus a 20% penalty. The key is to treat it as a medical retirement account until 65, then it becomes a general retirement account.
