The Health Savings Account Is the Most Misunderstood Account in Your Financial Life

Open enrollment arrives once a year. Most people spend more time picking a streaming show than evaluating their health savings account. They see "HSA," they understand it as a health expense account, and they move on.

That assumption may be costing them more than they realize.

The HSA is the only account in the U.S. tax code that offers a genuine triple tax advantage: contributions go in pre-tax, the money grows tax-free, and qualified withdrawals come out tax-free. Not two of those. All three. No other account works this way.

Good stewardship means using what's available wisely. The HSA is worth understanding in full.

‍

What Is a Health Savings Account, Really?

A health savings account is a tax-advantaged account for people enrolled in a qualifying High Deductible Health Plan (HDHP). Contributions go in pre-tax, and the money can be withdrawn tax-free for qualified medical expenses: doctor visits, prescriptions, dental care, vision, and a fairly broad list of other eligible costs.

But the better frame is this: the HSA is a health investment account. The money doesn't have to be spent this year. It can be invested, held for decades, and given opportunity to grow into a meaningful reserve. The word "savings" in the name undersells what it can do.

One thing that catches people off guard: the HSA differs from the FSA in that the HSA funds belong to you, not your employer. Like a 529 plan for education, the account goes with you when you change jobs, and you can transfer it to a different custodian if you want better investment options or lower fees. Some employer-linked HSAs limit fund choices or charge monthly fees. If yours does, you may have better options available.

The Triple Tax Advantage: No Other Account Does All Three

This is where most people's eyes widen, and with good reason.

A traditional 401(k) gives you a tax deduction going in and taxes you on the way out. A Roth IRA reverses the order: taxed going in, tax-free coming out. Both offer tax-free growth inside the account. That's two advantages each.

The HSA: tax deduction going in, tax-free growth inside, tax-free withdrawals for qualified medical expenses. Three advantages, no asterisks.

The IRS rarely gives you something for nothing. When it does, faithful stewardship means paying attention.

‍

Do You Qualify?

Eligibility comes down to one primary requirement: you must be enrolled in a qualifying High Deductible Health Plan on the first day of the month you want to contribute.

For 2026, a qualifying HDHP must carry a minimum annual deductible of $1,700 (self-only) or $3,400 (family), with maximum out-of-pocket limits of $8,500 and $17,000 respectively. (Source: IRS Rev. Proc. 2025-19.) If your plan doesn't meet these thresholds, you're not eligible to contribute, even if you have an HSA account open.

You're also ineligible if you're enrolled in Medicare, if you're claimed as a dependent on someone else's return, or if you have other disqualifying coverage outside the HDHP. There are limited exceptions, including rules around telehealth coverage that Congress has adjusted in recent years. If you're unsure whether your current plan qualifies, your plan's Summary Plan Description or your HR team can confirm it.

One important clarification: you can own and use an existing HSA even after you're no longer eligible to contribute. If you switch off an HDHP mid-career, the money already saved stays yours, continues to grow, and can still be withdrawn tax-free for qualified medical expenses.

‍

How Do You Open One?

If your employer's benefits package includes an HSA, they'll point you to a custodian. That's a reasonable starting point, but not necessarily the final word. Some employer-linked HSAs carry fees or offer limited investment options. You're allowed to transfer your balance to a different institution, and it may be worth comparing before you assume you're stuck.

For 2026, contribution limits are $4,400 (self-only) or $8,750 (family). If you're 55 or older, a $1,000 catch-up contribution is available on top of that. (Source: IRS Rev. Proc. 2025-19.)

Contributions made through payroll are pre-tax and avoid FICA taxes in addition to income tax, a small but real additional advantage over contributing directly and deducting on your return. Either method works; payroll is typically more efficient.

Note: Some states do not conform to the federal HSA deduction. If you live in one of those states, the state-level tax treatment is different. Ask your CPA or tax professional.

‍

Should You Max It Out?

In most cases, yes, if the cash flow supports it.

Here's the logic. If you invest your HSA contributions rather than spending them down each year, and pay routine medical costs out of pocket, the account can compound over time into a meaningful reserve. A family maxing contributions for 20 years, earning a 7-8% average return, could accumulate well over $200,000. That's a significant asset, one that went in pre-tax and grew without a tax bill along the way.

‍

Should I pay with my HSA or with cash?

Here’s the simple way to think about it:

• If you need the cash, use the HSA to pay the bill.
• If you don’t need the cash, pay out of pocket and keep the HSA invested — but save the receipt (see below).

Why? Because paying out of pocket doesn’t “waste” the HSA benefit. You can pay with cash now and reimburse yourself later.

There is no time limit on reimbursing yourself for past qualified medical expenses, as long as the expense occurred after you opened the HSA and hasn't been reimbursed from another source.

That’s so monumental I want to say it again: you can use your HSA funds to reimburse yourself for past qualified medical expenses (that haven’t been reimbursed elsewhere and occurred after you opened the HSA) no matter how long ago those expenses were incurred.

So, if you opened an HSA 10 years ago, that means a receipt from a dental procedure 6 years ago can support a tax-free withdrawal 10 years from now. The IRS does not impose a deadline. Keep the documentation, and the math works whenever you need it.

This reframes the question. Instead of choosing between "spend the HSA now" or "let it grow," you can do both: pay medical expenses out of pocket today, save the receipts, and take a tax-free reimbursement in a future year when it serves you better. For anyone who can absorb routine medical costs from cash flow, this is a meaningful long-term advantage.

I’d be remiss not to mention one lesser-known provision—the Qualified HSA Funding Distribution (QHSAFD). But I need to forewarn, that besides being an impossible-to-pronounce acronym, this option has real complexity. You need to consult a professional for this one. The QHSAFD allows a once-in-a-lifetime direct transfer from a traditional or Roth IRA to your HSA, up to the annual contribution limit (active SEP and SIMPLE IRAs are not eligible). It can make sense in specific planning scenarios, for instance a year when cash flow doesn't allow a full HSA contribution but IRA assets could be redirected. It comes with a 12-month HDHP testing period and consequences for losing coverage during that window. It's not a casual move, and it's worth discussing with an advisor before attempting.

‍

What Happens at Age 65?

The most common objection: "What if I stay healthy and don't end up spending it?"

At 65, the HSA changes shape in a really cool way: the 20% penalty for non-medical withdrawals disappears. You can withdraw funds for any purpose and simply pay ordinary income tax, the same treatment you'd get from a traditional IRA or 401(k) distribution. No more 20% penalty on top.

Qualified medical withdrawals remain entirely tax-free, same as always.

This means the HSA functions in two modes after 65: a tax-free medical reserve and a penalty-free income source for everything else. If you reach retirement with a large balance and strong health, you have a flexible asset that either covers healthcare costs tax-free or provides income with one layer of taxation.

And the healthcare piece is worth taking seriously. Healthcare costs in retirement routinely run into the six figures for most retirees. A purpose-built, invested reserve for those costs is rarely wasted.

Using Your HSA to Pay Long-Term Care Premiums

One of the most overlooked qualified expenses under the HSA is also one of the most strategically relevant for retirement planning: long-term care insurance premiums.

Tax-qualified LTC insurance premiums are treated as qualified medical expenses under IRC §213(d), which means you can pay them tax-free from your HSA — up to an annual limit set by the IRS based on your age at year-end. Those limits increase as you get older:

Age at year-end2026 limit40 or under$50041–50$93051–60$1,86061–70$4,96071 or older$6,200

(Source: IRS Rev. Proc. 2025-32)

Consider what that means in practice. A 64-year-old paying $4,500 in annual LTC premiums can cover the entire premium tax-free from their HSA — money that went in pre-tax, grew tax-free, and came out tax-free to fund coverage that protects the family from one of retirement’s largest unplanned expenses. The triple tax advantage applied to a real planning problem.

A few rules worth knowing. First, you cannot do both: if you use HSA funds to pay LTC premiums, you cannot also claim those same dollars as an itemized deduction on Schedule A. The IRS does not allow double-dipping. Second, only tax-qualified policies under IRC §7702B are eligible. Most modern standalone LTC policies qualify; many hybrid life/LTC policies do not unless the LTC premium is separately identifiable in the contract. Third, the spousal angle is worth knowing: you can use your own HSA to pay LTC premiums for your spouse, subject to your spouse’s own age-based limit. For a couple where both have LTC coverage, that’s potentially double the tax-free coverage funding.

For anyone building an HSA with an eye toward retirement and wondering what to do with it before the estate planning question comes up — funding long-term care coverage is one of the most direct and tax-efficient uses available.

‍

What Happens When You Die With Money in It?

This is the question most people never think to ask. The answer matters for how you plan around the account — and it's where the stewardship lens gets interesting.

If your spouse is the named beneficiary, the transition is clean. The HSA becomes theirs at the moment of your death, retaining all tax advantages. No tax event. They can continue using it, investing it, and treating it as their own account.

If a non-spouse inherits the account (an adult child, a sibling), the rules are significantly harsher. The HSA ceases to be an HSA at the date of death. The full balance becomes taxable ordinary income to the beneficiary in the year of your death. On a $250,000 account, that can be an enormous tax bill, potentially pushing an heir into the highest marginal bracket in a single year.

This is importantly different from an inherited IRA, where non-spouse beneficiaries generally have up to 10 years to distribute the funds. With an HSA, there's no spreading the tax hit. The whole balance lands in one tax year.

One partial relief: a non-spouse beneficiary can reduce the taxable amount by paying the deceased's outstanding qualified medical expenses within 12 months of death. That deadline is firm. The IRS grants no extensions, so the estate needs to move quickly.

But here is a theologically interesting tax planning idea:

If you name a qualified 501(c)(3) organization as your HSA beneficiary, the tax event does not occur. Charities don't pay income tax. The full balance passes to the cause, untouched, exactly as intended.

For anyone who has already determined that part of their estate will go toward ministry, a church, or a cause they care about — the HSA may be the most efficient vehicle to fund that commitment. It can compound tax-free for decades and land exactly where you meant it to go, with nothing surrendered to taxes along the way.

Scripture doesn't have a lot to say about HSA beneficiary designations specifically, but it has quite a bit to say about the posture behind giving: "Each of you should give what you have decided in your heart to give, not reluctantly or under compulsion" (2 Cor. 9:7). Pre-planning the destination of your HSA is faithful stewardship in light of a your life’s expected time horizon.

The practical framework looks like this: if you're married, it’s almost always best to name your spouse as primary beneficiary. Full stop. If you want to leave money to your children, a brokerage account or Roth IRA treats non-spouse heirs far more kindly, so consider holding wealth intended for them in those vehicles instead. And if you have charitable intent, your HSA may be the best-fit account you have.

HSA vs. FSA: A Quick Note

These two accounts are easy to confuse. They work very differently.

A Flexible Spending Account (FSA) is employer-owned, subject to a use-it-or-lose-it rule with very limited rollover, and typically cannot be invested for long-term growth. It's a current-year budgeting tool for predictable medical costs.

An HSA belongs to you, rolls over indefinitely, can be invested, and follows you when you change jobs.

They typically can't coexist. Having a general-purpose FSA usually disqualifies you from contributing to an HSA in the same year. A "limited purpose" FSA covering only dental and vision can run alongside an HSA without disqualifying you. If your employer offers both, understand which type of FSA is on the table before enrolling.
