How to Use an HSA for Retirement: 7 Strategies You May Be Overlooking

When you think about saving for retirement, a 401(k) or IRA probably comes to mind first.

Your Health Savings Account might not.

For many eligible individuals, an HSA is primarily viewed as a place to set aside money for this year’s doctor visits, prescriptions, deductibles, and other qualified medical expenses.

But an HSA can potentially serve another purpose: helping prepare for healthcare expenses later in life while providing valuable tax benefits along the way.

And research suggests many Americans may not be taking full advantage of that opportunity.

According to an August 2026 Barron’s article discussing research from the Employee Benefit Research Institute (EBRI), the average HSA balance reached $5,532 in 2024, an increase of nearly 17% from the prior year’s $4,747 average.

Yet the same research found that only 18% of HSA account holders invested their balances in something other than cash.

That doesn’t mean everyone should invest their HSA balance.

Someone expecting to use the money for near-term medical expenses may have a very different strategy from someone who can leave the account untouched for years.

But it does raise an important financial-planning question:

Are you treating your HSA only as a way to pay today’s healthcare bills when it could potentially play a larger role in your long-term financial plan?

What Is a Health Savings Account?

A Health Savings Account, or HSA, is a tax-advantaged account available to eligible individuals who meet applicable requirements, including coverage under a qualifying high-deductible health plan.

Unlike a traditional health insurance benefit that simply helps pay medical expenses, an HSA is an account you own.

Money contributed to the account can be used to pay qualified medical expenses, and unused HSA balances can generally remain in the account from year to year.

That last point is important.

You don’t necessarily have to spend your entire HSA balance during the year in which you contribute it.

For someone who remains eligible and continues accumulating HSA assets, the account may potentially grow into a resource for future healthcare expenses—including expenses incurred during retirement.

Why Are HSAs So Tax-Advantaged?

HSAs receive unusually favorable federal tax treatment.

Depending on how contributions are made and applicable tax rules:

• Eligible HSA contributions can generally be made on a pre-tax or tax-deductible basis;
• Earnings within the account generally aren’t subject to current federal income tax; and
• Withdrawals used for qualified medical expenses can generally be received free of federal income tax.

These three features are why HSAs are often described as having a “triple tax advantage.”

However, state tax treatment can differ, so the federal tax treatment of an HSA shouldn’t automatically be assumed to apply identically in every state.

The combination can nevertheless make an HSA worth considering as part of a broader tax and retirement strategy for eligible individuals.

HSA Strategy #1: Understand What the Account Can Do Before You Spend It

The first strategy isn’t complicated:

Understand the account you’re contributing to.

It’s easy to think of an HSA as a specialized checking account for healthcare.

You contribute money.

You go to the doctor.

You swipe the HSA card.

Done.

And there’s nothing inherently wrong with using an HSA that way.

Paying qualified medical expenses is one of the primary purposes of the account.

But automatically spending HSA dollars every time a medical bill arrives may mean overlooking the account’s longer-term potential.

If you don’t need to use all of the HSA balance today, unused dollars may remain available for qualified medical expenses in future years, subject to applicable HSA rules.

That can become increasingly valuable as retirement approaches because healthcare expenses don’t necessarily disappear when your paycheck does.

HSA Strategy #2: Know Whether You’re Eligible to Contribute

Before discussing contribution or investment strategies, there’s a more fundamental question:

Are you eligible to contribute to an HSA?

Simply having medical expenses doesn’t make someone eligible.

HSA contribution eligibility generally requires coverage under a qualifying high-deductible health plan and compliance with other applicable requirements.

Other health coverage can affect eligibility as well.

That’s why it’s important to distinguish between:

Owning an existing HSA

and

Being eligible to make new contributions to an HSA.

You may retain an HSA you’ve already established even if your circumstances later change, but that doesn’t necessarily mean you can continue making new contributions.

This distinction becomes particularly important as retirement and Medicare approach, which we’ll discuss later in this article.

HSA Strategy #3: Consider Whether You Need to Spend the HSA Today

Suppose you have a $1,000 qualified medical expense.

You also have $1,000 available in your HSA.

The obvious solution may seem to be paying the bill directly from the HSA.

That may be entirely appropriate.

But if you can comfortably pay the medical expense using other available cash flow, another option may be to leave the HSA assets in the account for future qualified medical expenses.

Why might someone consider doing that?

Because money remaining in an HSA may have additional time to potentially grow without current federal income taxation, depending on how the account is invested.

That can create an interesting planning trade-off:

Use the tax-advantaged dollars today, or preserve them for potential healthcare expenses later.

There isn’t one correct answer for everyone.

Someone with limited cash reserves may have good reason to use HSA dollars for current medical expenses.

Someone with sufficient cash flow and a long time horizon may decide that preserving some HSA assets better fits their broader plan.

The important point is that using the HSA immediately isn’t necessarily the only choice.

Why Healthcare Costs Make the HSA Relevant to Retirement Planning

Retirement planning often focuses on the expenses people look forward to:

• Travel;
• Hobbies;
• Time with family;
• A second home;
• Dining and entertainment; and
• Other lifestyle goals.

Healthcare is different.

It may not be the retirement expense you’re most excited to plan for, but it can be an important part of the budget.

Premiums, deductibles, copays, prescriptions, dental care, vision care, and other eligible expenses can continue throughout retirement.

That gives HSA dollars a potentially valuable long-term job.

Instead of viewing the account only as a way to pay medical bills during your working years, eligible individuals may also consider how accumulated HSA assets could help address qualified healthcare expenses later.

HSA Strategy #4: Decide Whether Some of Your HSA Should Be Invested

This is one of the most interesting findings in the EBRI research cited by Barron’s.

Only 18% of HSA account holders invested their HSA assets in something other than cash, according to the research discussed in the article.

EBRI observed that account holders appeared, on average, to be using HSAs more like specialized checking accounts than investment accounts, although that behavior tended to change the longer someone held the account.

Does that mean the other 82% should immediately invest their HSA balances?

No.

Once again, the purpose and time horizon of the money matter.

If you expect to need most of your HSA balance for medical expenses this year, exposing those dollars to significant market volatility may not fit your needs.

But if part of your HSA is intended for healthcare expenses 10, 20, or even 30 years from now, leaving the entire balance in cash may deserve another look.

Think of Your HSA in Terms of Time Horizon

One way to evaluate an HSA is to separate the account conceptually into different jobs.

Near-term HSA money may need to remain relatively liquid if you expect to use it for upcoming qualified medical expenses.

Longer-term HSA money may have a different purpose if you’re accumulating it for healthcare expenses later in life.

Those two pools don’t necessarily need to be managed identically.

For example, someone who expects $3,000 of qualified medical expenses during the coming year may want to think differently about that $3,000 than an additional HSA balance they don’t expect to touch for many years.

This is similar to the broader financial-planning principle we discussed in our article about how much cash to keep:

Money you need soon and money you don’t expect to need for decades have different jobs.

Investing an HSA Still Involves Investment Risk

The tax advantages of an HSA don’t eliminate investment risk.

If HSA assets are invested in securities, their value can fluctuate.

An investor who needs to withdraw money for a medical expense during a market decline could potentially be forced to sell an investment at an unfavorable time.

That’s why the question shouldn’t simply be:

“Can I invest my HSA?”

A better set of questions may be:

• When do I expect to need this money?
• How much should remain available for near-term healthcare costs?
• How much could potentially remain invested for longer-term needs?
• What investment choices does my HSA provider offer?
• What fees or minimum-balance requirements apply?
• How much investment risk am I comfortable taking?
• How does the HSA fit with my other retirement assets?

The answers may change over time.

Someone in their 30s with decades until retirement may view the account differently from someone who is approaching Medicare eligibility and expects significant healthcare spending.

An HSA Shouldn’t Be Viewed in Isolation

For someone trying to maximize retirement savings, the existence of an HSA can raise another question:

“Where should my next dollar go?”

Should it go to the HSA?

A 401(k)?

A Roth IRA?

A Traditional IRA?

A taxable investment account?

Or should the money be used for another financial priority?

There isn’t a universal order that’s appropriate for everyone.

Employer matching contributions, taxes, liquidity needs, debt, emergency savings, healthcare expenses, retirement goals, account eligibility, and other factors can all affect that decision.

That’s why an HSA can be an important part of a retirement strategy without automatically being the first or most important account everyone should fund.

The goal is to understand how the HSA works alongside the rest of your financial plan.

HSA Strategy #5: Keep Your Qualified Medical Expense Receipts

If you’re using an HSA as part of a longer-term strategy, good recordkeeping can become extremely important.

Here’s why.

Generally, there is no federal requirement that you reimburse yourself from an HSA in the same year you incur a qualified medical expense.

If an eligible medical expense was incurred after your HSA was established, you may be able to pay that expense using other funds, leave the HSA money in the account, and reimburse yourself from the HSA at a later date, provided the expense otherwise qualifies and you maintain appropriate documentation.

Consider a simple example.

Suppose you incur a $2,000 qualified medical expense this year.

You could use $2,000 from your HSA to pay the bill.

Or, if your financial situation allows, you could pay the bill with other available funds and leave the $2,000 in the HSA.

Years later, you may potentially reimburse yourself from the HSA for that previously unreimbursed qualified expense, assuming applicable requirements are satisfied and you have the records necessary to substantiate it.

Why would someone consider doing this?

Leaving money in the HSA can provide additional time for the assets to potentially grow on a tax-advantaged basis.

But this strategy comes with an important responsibility:

You need to keep good records.

What HSA Records Should You Keep?

If you’re planning to delay reimbursement, consider maintaining organized documentation of qualified medical expenses.

That may include:

• Medical bills;
• Receipts;
• Explanation of Benefits statements;
• Proof of payment;
• The date the expense was incurred;
• The individual for whom the expense was incurred; and
• Records showing whether the expense was reimbursed from another source.

You should also be able to establish that the expense occurred after the HSA was established and that you didn’t previously receive reimbursement for the same expense.

Simply having a bank or credit-card statement showing a payment may not provide all the information you eventually need.

And if you’re considering delaying reimbursement for many years, think about where those records will be stored.

A receipt you plan to use decades from now isn’t very helpful if you can’t find it.

HSA Strategy #6: Think About Healthcare Costs in Retirement

One reason an HSA can be relevant to retirement planning is straightforward:

Retirement doesn’t eliminate healthcare expenses.

Even after Medicare eligibility begins, retirees can continue to face premiums and out-of-pocket healthcare costs.

Depending on the expense and applicable HSA rules, accumulated HSA assets may be available to pay a variety of qualified medical expenses.

That can make the HSA different from simply accumulating another general-purpose retirement account.

The account can be positioned around a specific future need: healthcare.

For someone approaching retirement, it may therefore be helpful to think beyond the question:

“How much do I need to retire?”

and also ask:

“How will I pay for healthcare throughout retirement?”

What Can You Use an HSA for in Retirement?

HSA funds can generally continue to be used for qualified medical expenses after you retire.

Depending on applicable rules, qualified expenses may include certain:

• Deductibles and copayments;
• Prescription medications;
• Dental expenses;
• Vision expenses;
• Other eligible medical expenses; and
• Certain insurance premiums permitted under HSA rules.

Not every healthcare or insurance expense qualifies, so it’s important to verify an expense before assuming an HSA distribution will receive tax-free treatment.

That becomes especially important with insurance premiums because HSA rules generally limit which premiums qualify for tax-free reimbursement.

Can You Use an HSA to Pay Medicare Premiums?

After age 65, HSA funds can generally be used tax-free for certain Medicare premiums, assuming applicable requirements are satisfied.

For example, certain Medicare Part B, Part D, and Medicare Advantage premiums may qualify.

However, Medicare supplement insurance premiums generally do not qualify for tax-free HSA reimbursement.

Those distinctions matter because simply labeling an expense a “Medicare premium” doesn’t necessarily tell you whether it qualifies.

If you’re planning to use HSA assets for Medicare-related expenses, review the specific expense and current tax rules before taking the distribution.

HSA Strategy #7: Understand What Changes at Age 65

Age 65 is an important HSA milestone, but not because your HSA disappears.

Your HSA remains yours.

You can continue using the account for qualified medical expenses, and qualified withdrawals can generally continue to receive favorable federal income-tax treatment.

What changes is the treatment of certain nonmedical withdrawals.

Before age 65, an HSA distribution used for something other than a qualified medical expense is generally subject to ordinary income tax and may also be subject to an additional 20% tax.

After age 65, the additional 20% tax generally no longer applies.

A nonqualified withdrawal can still be subject to ordinary income tax, but the additional penalty generally goes away.

This creates an important distinction:

After age 65, an HSA can generally be used for nonmedical purposes without the additional 20% tax, but that does not make the withdrawal tax-free.

Qualified medical withdrawals and nonmedical withdrawals still receive different tax treatment.

What Happens to Your HSA When You Enroll in Medicare?

This is one of the most important HSA planning issues for people approaching retirement.

You generally cannot continue contributing to an HSA once you’re enrolled in Medicare.

But that doesn’t mean you lose the HSA you’ve already accumulated.

You can continue owning the account.

You can continue investing HSA assets if your account permits it.

And you can continue taking distributions for qualified medical expenses.

The issue is generally your eligibility to make new contributions.

Medicare enrollment can also involve timing considerations, particularly for individuals who delay Medicare while continuing to work. In some circumstances, Medicare Part A coverage can be retroactive, which can affect HSA contribution eligibility for earlier months.

Because of that potential overlap, someone approaching Medicare enrollment may want to coordinate HSA contributions carefully rather than assuming contributions can continue through the date they submit a Medicare application.

Don’t Wait Until Medicare Enrollment to Review Your HSA

If you’re approaching age 65, HSA planning ideally begins before Medicare enrollment.

Questions to consider may include:

• When do I expect to enroll in Medicare?
• When should HSA contributions stop?
• Am I eligible to make a full contribution for the year?
• Do I have an employer contribution that needs to be considered?
• How much of the HSA should remain liquid?
• How much, if any, should remain invested?
• Do I have unreimbursed qualified medical expenses from prior years?
• How might I use the HSA during retirement?

The answers can depend on your employment, health coverage, Medicare enrollment date, tax situation, and other circumstances.

For that reason, Medicare and HSA decisions shouldn’t necessarily be made independently from one another.

HSA vs. FSA: What’s the Difference?

Health Savings Accounts and Flexible Spending Accounts are both associated with healthcare expenses, but they’re not interchangeable.

Understanding the distinction is particularly important if you’re deciding how healthcare benefits fit into your broader financial plan.

Feature	HSA	Health FSA
Who owns it?	The individual owns the HSA.	The FSA is generally an employer-sponsored benefit.
Can unused money remain available?	HSA balances generally carry forward from year to year.	FSA rules differ. A plan may provide certain carryover or grace-period provisions, subject to applicable rules.
Can the account follow you when you change jobs?	Generally, yes. The HSA belongs to you.	Generally not in the same way because the FSA is tied to the employer’s plan.
Can the money potentially be invested?	Some HSA providers allow investing once applicable account requirements are met.	Health FSA balances generally aren’t investment accounts.
Does eligibility depend on health coverage?	Yes. HSA contribution eligibility generally requires qualifying coverage and satisfaction of other requirements.	Eligibility is determined by the employer’s benefit plan and applicable FSA rules.

One of the biggest differences is that an HSA can potentially become a long-term asset.

Unused HSA money can generally remain in the account, and the account belongs to the individual.

That makes an HSA potentially relevant not just to annual healthcare spending but also to longer-term financial and retirement planning.

Does an HSA Expire When You Retire?

No.

Retiring doesn’t, by itself, cause your HSA balance to disappear.

The account belongs to you, and unused funds generally remain available.

What can change is your ability to make additional contributions.

For example, Medicare enrollment generally makes you ineligible to make new HSA contributions, but you can continue using previously accumulated HSA assets.

That’s an important distinction for someone who has spent years building an HSA balance specifically for retirement healthcare costs.

Can You Have an HSA and a 401(k) or IRA?

Yes, assuming you otherwise meet the requirements applicable to each account.

An HSA doesn’t necessarily replace a 401(k), IRA, or other retirement account.

They serve different purposes and have different contribution limits, withdrawal rules, eligibility requirements, and tax characteristics.

For some households, the more useful planning question isn’t:

“Which account is best?”

It’s:

“How should these accounts work together?”

A financial plan may involve deciding how much to direct toward an employer retirement plan, HSA, IRA, taxable investments, emergency savings, debt reduction, and other priorities.

The appropriate mix depends on the individual household.

Should You Max Out Your HSA?

For an eligible individual, contributing the maximum allowed amount to an HSA can provide valuable tax benefits and additional resources for future qualified medical expenses.

But that doesn’t automatically mean maximizing an HSA should come before every other financial priority.

Before deciding how much to contribute, consider factors such as:

• Your available cash flow;
• Emergency savings;
• High-interest debt;
• Employer retirement-plan matching contributions;
• Expected medical expenses;
• Other retirement savings;
• Tax considerations;
• Your investment time horizon; and
• Your broader financial goals.

The maximum amount you’re legally allowed to contribute and the amount that makes sense for your financial plan aren’t necessarily the same thing.

Frequently Asked Questions About HSAs and Retirement

Can I use my HSA after I retire?

Yes. An existing HSA generally remains yours after retirement. You can continue using HSA funds for qualified medical expenses, subject to applicable rules.

Can I contribute to an HSA after enrolling in Medicare?

Generally, no. Medicare enrollment generally makes an individual ineligible to make new HSA contributions. However, previously accumulated HSA funds remain available.

What happens if I use HSA money for nonmedical expenses after age 65?

After age 65, nonqualified HSA distributions generally aren’t subject to the additional 20% tax that can apply at younger ages. However, the distribution is generally subject to ordinary income tax if it isn’t used for a qualified medical expense.

Does an HSA expire?

No. HSA balances generally carry forward from year to year, and the account belongs to the individual.

Do I lose my HSA if I change jobs?

Generally, no. An HSA is individually owned, so changing employers doesn’t ordinarily cause you to forfeit the account.

Can I invest the money in my HSA?

Some HSA providers allow account holders to invest some or all eligible HSA balances. Investment choices, minimum cash requirements, and fees vary by provider. Investing also introduces the possibility of loss, so time horizon and expected healthcare needs should be considered.

Can I reimburse myself years later for a medical expense?

Under current federal HSA rules, there generally isn’t a deadline requiring reimbursement in the same year an eligible expense is incurred. An expense generally must have been incurred after the HSA was established, must qualify under applicable rules, and must not have already been reimbursed or otherwise improperly claimed. Maintaining adequate documentation is important.

Can I use my HSA for Medicare premiums?

Certain Medicare premiums can generally qualify for tax-free HSA reimbursement after age 65, subject to applicable rules. However, Medicare supplement insurance premiums generally don’t receive the same treatment.

Are You Treating Your HSA Like a Checking Account?

The EBRI research discussed by Barron’s provides an interesting snapshot of how Americans are using HSAs.

Average balances are growing.

HSA enrollment has expanded.

Yet relatively few account holders in the research were investing their HSA balances beyond cash.

That doesn’t prove those account holders are doing anything wrong.

Many may need those dollars for current healthcare expenses.

But it does provide a reason to ask whether your own HSA strategy matches your circumstances.

Are you using the account primarily to pay today’s bills?

Are you accumulating money for future healthcare expenses?

Are you investing some of the balance for longer-term needs?

Are you keeping receipts for qualified expenses you may reimburse later?

Are you approaching Medicare without a plan for when HSA contributions should stop?

Those are very different uses of the same account.

An HSA Can Be More Than a Medical Spending Account

For eligible individuals, an HSA can potentially play several roles throughout a financial life.

It can help pay today’s qualified medical expenses.

It can provide a place to accumulate money for future healthcare needs.

It may provide investment opportunities for money with a longer time horizon.

And it can potentially become a resource for qualified healthcare expenses during retirement.

But the tax advantages alone don’t determine the right strategy.

Your healthcare needs, cash flow, investment horizon, Medicare timing, tax situation, and other financial priorities all matter.

That’s why the better question isn’t simply:

“Am I contributing to an HSA?”

It may be:

“Am I using my HSA in a way that supports the rest of my financial plan?”

How Does Your HSA Fit Into Your Retirement Plan?

Healthcare planning, retirement income, investments, and taxes don’t exist independently from one another.

A decision about whether to spend, save, or invest HSA assets can affect the resources available later in retirement.
