Your HSA is being taxed because you withdrew money for something that doesn't count as a may have access to medical expense under IRS rules, or because you're over 65 and taking distributions for non-medical reasons

An HSA (Health Savings Account) grows tax-free and lets you withdraw money tax-free — but only for specific medical costs. The IRS publishes a list of what counts. If you take money out for anything else, you owe income tax on that withdrawal plus a 20% penalty, unless you're 65 or older (then you skip the penalty but still owe the income tax).

The tax bill arrives because your HSA custodian — the bank or financial company holding your account — reports the withdrawal to the IRS on Form 1099-SA. If the IRS later finds out the expense wasn't may have access to, you'll owe back taxes and penalties when you file your return, or the IRS may contact you directly.

Some withdrawals look medical but aren't covered. Others are covered but you didn't keep the right paperwork to prove it. A few people withdraw money by mistake or don't realize the rules have changed.

Key Takeaways

  • Withdrawals for non-may have access to expenses trigger both income tax and a 20% penalty if you're under 65, even if the money came from your own contributions.
  • Common non-may have access to expenses include cosmetic procedures, gym memberships, over-the-counter vitamins without a prescription, and dental work that your plan doesn't cover.
  • You can withdraw money tax-free for Medicare premiums, long-term care insurance premiums, and medical expenses after you turn 65, even if you're no longer working.
  • Keeping receipts and explanation of benefits documents for every withdrawal protects you if the IRS questions whether an expense was truly medical.
  • If you withdrew money for a non-may have access to expense by mistake, you may be able to return it to your HSA within a limited time frame to avoid the tax and penalty.

What counts as a may have access to medical expense

The IRS maintains a detailed list of may have access to medical expenses. They include doctor visits, hospital stays, prescription drugs, dental work (fillings, crowns, root canals), vision care (glasses, contacts, eye surgery), hearing aids, mental health treatment, and physical therapy. They also cover medical equipment like crutches, wheelchairs, and blood pressure monitors.

Over-the-counter medicines and supplies count only if you have a prescription from a doctor. Aspirin, cold medicine, antacids, and bandages without a prescription do not may have access to. Vitamins and supplements almost never may have access to unless a doctor prescribes them to treat a specific medical condition.

Expenses your health insurance doesn't cover can still be may have access to — for example, if your plan has a high deductible and doesn't pay for acupuncture, you can use HSA money for acupuncture if a doctor says it's medically necessary. The key is whether the IRS considers it medical, not whether your insurance does.

Common expenses that trigger HSA taxes

Cosmetic procedures are the most frequent source of HSA tax bills. Botox, teeth whitening, hair removal, and facelifts are not may have access to, even if a doctor performs them. Reconstructive surgery after an accident or illness is usually may have access to, but purely cosmetic work is not.

Gym memberships and fitness classes do not may have access to, even if your doctor recommends exercise. Weight loss programs and diet plans are not may have access to unless a doctor prescribes them to treat obesity as a medical condition, and even then only the medically necessary portion may count.

Dental work that your insurance doesn't cover is a gray area. If your plan excludes orthodontics, you cannot use HSA money for braces. If your plan excludes cosmetic bonding, you cannot use HSA money for that either. But if your plan covers fillings and you get a filling, that's may have access to even if you pay out of pocket.

Long-term care insurance premiums are may have access to, but life insurance premiums are not. Nursing home care is may have access to, but assisted living may not be, depending on whether the facility provides significant medical services.

How the IRS finds out about non-may have access to withdrawals

Your HSA custodian sends Form 1099-SA to the IRS every year, reporting the total amount you withdrew. The form does not say what you spent the money on — it just reports the number. The IRS matches this form to your tax return.

If you report the withdrawal as non-taxable on your return (which you should if it was truly may have access to), the IRS usually accepts it. If you don't report it at all, or if the IRS later learns the expense wasn't may have access to, you'll receive a notice asking you to pay the tax and penalty.

The IRS can also audit your HSA account directly, especially if you take large withdrawals or if your account shows a pattern of withdrawals that don't match typical medical spending. An audit request will ask you to provide receipts and documentation proving the expenses were may have access to.

What happens if you can't prove an expense was may have access to

If the IRS questions a withdrawal and you cannot produce a receipt or explanation of benefits showing the expense was medical, the IRS will treat it as non-may have access to. You'll owe income tax on the amount at your ordinary tax rate, plus a 20% penalty.

For example, if you withdrew $1,000 and cannot prove it was for a may have access to expense, and your tax bracket is 22%, you'll owe $220 in income tax plus $200 in penalty, for a total of $420. You'll also owe any interest that accrued while the tax was unpaid.

The penalty does not apply if you're 65 or older. After 65, you can withdraw HSA money for any reason and owe only income tax, not the 20% penalty. This makes an HSA function like a traditional IRA once you reach retirement age.

How to fix a non-may have access to withdrawal

If you withdrew money for a non-may have access to expense by mistake, you may be able to return it to your HSA within 60 days. This is called a return of funds or reversal. Contact your HSA custodian immediately and ask whether they allow reversals and what documentation they need.

Not all custodians permit reversals, and the rules vary. Some allow reversals only if you catch the mistake within days; others give you the full 60 days. Some require a written statement explaining why the withdrawal was non-may have access to. If your custodian allows it, the reversal erases the withdrawal from your account and from the Form 1099-SA, so no tax is owed.

If you've already filed your tax return and reported the withdrawal as non-may have access to, you can file an amended return (Form 1040-X) to correct it if you later return the money to your HSA. Keep documentation of the reversal from your custodian to attach to the amended return.

How to avoid HSA taxes going forward

Keep a receipt or explanation of benefits for every HSA withdrawal, even small ones. Store them in a folder or digital file organized by year. The IRS does not require you to submit receipts with your tax return, but you must have them if the IRS ever asks.

Before you withdraw money, check the IRS's Publication 502, which lists all may have access to medical expenses. If you're unsure whether an expense qualifies, call your HSA custodian or ask your doctor whether they can prescribe it (which often makes it may have access to).

If you're paying for something your health insurance doesn't cover, verify with your insurance company that it's truly not covered before using HSA money. Some people assume an expense isn't covered when it actually is, then use HSA money unnecessarily.

Track your HSA balance and withdrawals throughout the year. If you notice withdrawals you don't remember making, contact your custodian right away. Fraudulent or erroneous withdrawals should be reported and reversed as soon as possible.

Frequently Asked Questions

Can I use HSA money for my spouse's medical expenses?

Yes. You can use your HSA to pay for may have access to medical expenses for your spouse and any dependent children, even if they're not on your health insurance plan. The expense must still be may have access to — cosmetic procedures and non-medical items don't count just because a family member incurred them.

What if my doctor says an expense is medically necessary but the IRS doesn't cover it?

The IRS rules, not your doctor's opinion, determine whether an expense is may have access to. If the IRS doesn't list it in Publication 502, it's not may have access to, even if your doctor prescribes it. You can ask the IRS for a private letter ruling on an unusual expense, but this is slow and expensive.

Do I owe the 20% penalty if I'm over 65?

No. Once you turn 65, you can withdraw HSA money for any reason without the 20% penalty. You'll owe income tax on non-medical withdrawals, but not the penalty. This is why many people use HSA accounts as retirement savings vehicles.

Can I get my money back if I already paid the tax and penalty?

If you filed a return and paid tax and penalty on a withdrawal that was actually may have access to, you can file an amended return (Form 1040-X) within three years to request a refund. You'll need documentation proving the expense was may have access to. If you paid without filing a return, contact the IRS to discuss your options.

What if my HSA custodian made a mistake on the Form 1099-SA?

Contact your custodian immediately and ask them to issue a corrected Form 1099-SA (Form 1099-SA with a corrected indicator). Once they file the corrected form with the IRS, the error should be resolved. Keep a copy of the corrected form for your records.
