The HSA: The Most Underused Wealth-Building Account in Your Benefits Package

By David Samuel

Every fall, millions of employees click through open enrollment screens, glance at the Health Savings Account option, and file it away as “the account I use for band-aids and doctor copays.” That’s a shame, because the HSA isn’t just a health expense account — it’s arguably the single best wealth-building tool hiding in your benefits package, and almost nobody treats it that way.

A Triple Tax Advantage Nothing Else Matches

No other account in the U.S. tax code offers what an HSA offers: a deduction going in, tax-free growth while invested, and tax-free withdrawals when used for qualified medical expenses. Compare that to a 401(k) or traditional IRA, where you get the deduction and the growth but pay taxes on the way out. Or a Roth IRA, where you pay taxes going in but get tax-free growth and withdrawals. The HSA is the only account that wins on all three fronts simultaneously — which is why some financial planners quietly call it the best retirement account available, better even than a 401(k) match in certain scenarios.

For 2026, an eligible individual with self-only high-deductible health plan (HDHP) coverage can contribute up to $4,400, and those with family coverage can put in up to $8,750, with an additional $1,000 catch-up contribution allowed if you’re 55 or older. To qualify, your HDHP needs a minimum deductible of $1,700 for self-only or $3,400 for family coverage, with out-of-pocket maximums capped at $8,500 and $17,000 respectively.

Why Most People Use It Wrong

Here’s the disconnect: most HSA holders treat the account like a checking account for medical bills. They contribute just enough to cover the year’s copays and prescriptions, then spend it down to zero by December. That’s not wrong exactly — but it’s leaving enormous long-term value on the table.

The smarter play, if your cash flow allows it, is to pay current medical expenses out of pocket whenever possible and let your HSA balance sit and grow, invested in mutual funds or ETFs just like a 401(k). Most major HSA custodians let you invest balances above a small cash threshold. Left untouched for 10, 20, or 30 years, even modest contributions compound into a genuinely significant sum — tax-free the entire way.

The Receipt Strategy

This is the part that surprises most people: there’s no deadline on reimbursing yourself for a qualified medical expense. If you pay a $200 dental bill out of pocket today and simply save the receipt, you can reimburse yourself from your HSA five, ten, or twenty years from now — tax-free — regardless of how much the account has grown in the meantime. That means every medical expense you can afford to pay from your regular budget today is effectively a future tax-free withdrawal you’ve banked for later. Keep a simple folder or spreadsheet of qualified expenses and receipts, and you’ve built yourself an on-demand, tax-free withdrawal option for whenever you actually need the cash.

It Doesn’t Expire, and It Follows You

Unlike a Flexible Spending Account, HSA funds never expire and there’s no “use it or lose it” pressure. The account is yours — it stays with you if you change jobs, change insurance, or retire. And once you turn 65, the rules loosen even further: you can withdraw HSA funds for any purpose, not just medical expenses, and you’ll simply pay ordinary income tax on non-medical withdrawals, the same way you would from a traditional IRA. Used for qualified medical expenses, withdrawals remain tax-free for life, including in retirement when healthcare costs typically climb the fastest.

The Bottom Line

If you have access to an HSA-eligible health plan, the account deserves the same strategic attention you give your 401(k) — not an afterthought during open enrollment. Maximize contributions if you can, invest the balance instead of holding it in cash, save your medical receipts, and let compounding do the rest. Few benefits packages hand employees a better-engineered wealth-building tool than this one. The only thing standing between you and that advantage is treating the HSA like what it actually is: a long-term investment account that happens to also cover your medical bills.
