Tax-free growth — Investment gains, interest, and dividends inside the HSA are never taxed while in the account.
Tax-free withdrawals — Distributions used for qualified medical expenses are completely tax-free.

Contribution deadline April 15, 2027 for tax year 2026.
Employer contributions count toward the annual limit.
If you become HSA-eligible mid-year, you can use the "last-month rule" to contribute the full annual amount (but must remain eligible through December of the following year).

Short-term needs (using for medical expenses this year): Keep in cash or money market.
Medium-term (3-5 years): Target-date funds or balanced funds.
Long-term / Shoebox strategy (10+ years): Invest aggressively in low-cost index funds (total market, S&P 500, international).

Pay medical expenses out of pocket instead of using your HSA.
Save every receipt (digitally — photo or scan). Store in a dedicated folder (Google Drive, Dropbox, etc.).
Let your HSA grow tax-free for years or decades.
Reimburse yourself anytime — There is no time limit on reimbursement. The IRS confirms you can reimburse yourself for expenses incurred at any point after the HSA was established.
The expense must have been incurred after the HSA was opened.
Keep documentation (receipts, EOBs) indefinitely.
No deadline to submit for reimbursement.

Medical expenses Still tax-free (same as always).
Non-medical expenses Withdrawals for any purpose are taxed as ordinary income (like a Traditional IRA) but with no 10% penalty. Before 65, non-medical withdrawals incur a 20% penalty plus income tax.
Medicare premiums You can pay Medicare Parts B, C, and D premiums tax-free from your HSA. You cannot pay Medigap (supplemental) premiums.
No RMDs Unlike a 401(k) or Traditional IRA, HSAs have no required minimum distributions. You can let the money grow indefinitely.
Spousal inheritance If your spouse inherits the HSA, it becomes their HSA with full benefits. Non-spouse beneficiaries receive the balance as taxable income.
