Taxes
How a Health Savings Account can be deductible, grow tax-free, and come out tax-free for medical costs. 2027 contribution limits are $4,500 self-only / $9,000 family plus $1,000 at 55+ (Rev. Proc. 2026-24). Open-enrollment choice of HDHP vs copay plan lives in the HSA vs FSA guide.

Contributions are pre-tax (or deductible). Growth is tax-free. Qualified medical withdrawals are tax-free. After 65, non-medical withdrawals are taxed like a traditional IRA — still usable, just not magic.
That combination does not exist in a 401(k) or a brokerage account. If you have a real HDHP and can stand the deductible, maxing the HSA often beats extra IRA money.
You can reimburse yourself years later for qualified expenses you paid in cash, as long as the expense happened after the HSA was opened. Keep PDFs. This is how people use the HSA as a long-term compounding vehicle.

You need a qualifying high-deductible health plan, you cannot be enrolled in Medicare, and you generally cannot be claimed as a dependent. Confirm HDHP minimum deductibles for the year with IRS Pub 969.
Most custodians let you invest above a cash threshold. If you can pay current medical bills from cash and keep receipts, the HSA can act like a stealth retirement account.
