Why Your HSA Withdrawals Are Being Taxed and How to Avoid It

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

An HSA (Health Savings Account) grows tax-free and lets you withdraw money tax-free — but only for specific medical costs. If you take money out for anything else, the IRS taxes that withdrawal as ordinary income and adds a 20% penalty on top. The tax bill arrives when you file your return the following year, not when you make the withdrawal.

The most common reason for unexpected taxes is withdrawing for something you thought was medical but the IRS does not count that way. Gym memberships, cosmetic procedures, over-the-counter vitamins, and teeth whitening are frequent culprits. Less obvious: some dental work, vision correction, and mental health services only count if you meet specific conditions.

If you withdrew for a non-may have access to expense by mistake, you may be able to put the money back into your HSA within a limited window. If you withdrew for a may have access to expense but did not keep the right paperwork, you can still fix it — the IRS just needs proof you spent the money correctly.

Key Takeaways

• HSA withdrawals are taxed as income plus a 20% penalty if spent on anything other than IRS-may have access to medical expenses.
• Common non-may have access to expenses include gym memberships, cosmetic procedures, over-the-counter vitamins without a prescription, and teeth whitening.
• If you withdrew money by mistake, you can return it to your HSA within 60 days of the withdrawal and avoid the tax and penalty.
• Keeping receipts and explanations of what you spent on is the only way to prove to the IRS that a withdrawal was for a may have access to expense.

What counts as a may have access to medical expense

The IRS publishes a list of may have access to medical expenses in Publication 969. The broad categories are: insurance premiums (some types), doctor and dentist visits, hospital care, prescription drugs, medical equipment, and vision and hearing care. But the details matter — a dental crown counts, but teeth whitening does not. A prescription for vitamin D counts, but buying vitamin D off the shelf does not.

Mental health and therapy are may have access to expenses, but only if provided by a licensed practitioner. Massage therapy counts only if prescribed by a doctor for a specific medical condition, not for general wellness. Physical therapy counts. Acupuncture counts if performed by a licensed acupuncturist. Chiropractic care counts.

Over-the-counter medicines and supplies are a gray area. Bandages, pain relievers, allergy medicine, and antacids count. Vitamins and supplements do not count unless a doctor prescribes them for a diagnosed deficiency. Sunscreen does not count. Toothpaste and mouthwash do not count, but dental work does.

The tax and penalty that applies to non-may have access to withdrawals

When you withdraw money from your HSA for a non-may have access to expense, two things happen. First, the amount you withdrew is added to your taxable income for that year, and you pay income tax on it at your ordinary tax rate — which could be 12%, 22%, 24%, or higher depending on your income bracket. Second, the IRS adds a flat 20% penalty on top of the withdrawal amount itself.

Example: You withdraw $500 for a gym membership. That $500 becomes taxable income. If you are in the 22% tax bracket, you owe $110 in income tax. You also owe a $100 penalty (20% of $500). Your total bill is $210 for a $500 withdrawal. You do not pay this when ready — it shows up on your tax return when you file the following year.

The 20% penalty does not explore if you are over 65, disabled, or no longer covered by a high-deductible health plan. But the income tax still applies. If you are retired and on Medicare, withdrawals for non-may have access to expenses are still taxed and penalized.

How to prove a withdrawal was for a may have access to expense

The IRS does not automatically know what you spent your HSA money on. You need to keep records. The best record is a receipt from the provider — a doctor's bill, a pharmacy receipt, a hospital statement, a dental invoice. The receipt should show the date, the provider's name, what service or product you received, and the amount.

If the receipt does not clearly describe what you paid for, keep a note explaining it. For example, if a receipt just says "Dr. Smith — $150," write down that it was for an office visit for a sprained ankle. If you paid for multiple things on one bill, mark which items were medical and which were not.

You do not have to send receipts to the IRS when you file your return. But if the IRS audits your HSA withdrawals, you will need to produce them. Many people discover they are missing receipts only when they get an audit notice. Keeping a folder — digital or paper — with all HSA receipts and a straightforward list of what you spent on each month makes this much easier.

Returning money to your HSA if you made a mistake

If you withdrew money for a non-may have access to expense, you can put it back into your HSA within 60 days of the withdrawal. This is called a return of funds. When you return the money within that window, the withdrawal is treated as if it never happened — no tax, no penalty.

To return the money, contact your HSA custodian (the bank or financial company that holds your account) and ask how they handle returns of funds. Some custodians let you transfer money back online. Others require a form. You will need to tell them the date of the original withdrawal and the amount you are returning.

The 60-day window is strict. If you return the money on day 61, the IRS does not recognize it as a valid return, and you will owe tax and penalty on the full amount. Mark your calendar when you make a withdrawal you are unsure about, so you know your important date.

When the IRS taxes your HSA on your tax return

You do not receive a tax bill from the IRS when ready after a non-may have access to withdrawal. Instead, your HSA custodian reports the withdrawal to the IRS on a Form 1099-SA, which they send to you and the IRS by January 31 of the following year. When you file your tax return, you report the withdrawal and explain which part was may have access to (not taxed) and which part was non-may have access to (taxed).

If you do not report the non-may have access to withdrawal on your return, the IRS will eventually notice the Form 1099-SA and send you a bill for the tax and penalty. This can happen months or even years after you made the withdrawal. If you owe back taxes, you will also owe interest on top of the tax and penalty.

If you are unsure whether a withdrawal was may have access to, it is safer to report it as non-may have access to on your return and include a note explaining the situation. The IRS is more likely to work with you if you disclose the issue yourself than if they discover it during an audit.

HSA withdrawals after age 65 and Medicare

Once you turn 65, the rules change slightly. You can still withdraw money for may have access to medical expenses tax-free. But if you withdraw for a non-may have access to expense, you only owe income tax — the 20% penalty goes away. This makes non-may have access to withdrawals less expensive, but they are still taxed.

If you enroll in Medicare, your HSA does not automatically close, and you can keep using it. However, you cannot contribute new money to an HSA once you are on Medicare. You can withdraw money for may have access to expenses (including Medicare premiums, copays, and deductibles) tax-free. Non-may have access to withdrawals are taxed but not penalized.

Frequently Asked Questions

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

Yes. Your spouse does not have to be covered by your HSA or your health plan. As long as you are married and file taxes jointly, you can pay for your spouse's may have access to medical expenses with your HSA money tax-free. Keep receipts in your spouse's name to document the expense.

What if I withdrew for a may have access to expense but lost the receipt?

You can still prove the expense without the original receipt. A credit card or bank statement showing a charge to a doctor, pharmacy, or hospital is acceptable proof. A letter from the provider confirming the date and amount of the service also works. The IRS wants evidence that the money went to a may have access to provider for a medical purpose.

Does my HSA custodian tell me if a withdrawal is non-may have access to?

No. Your custodian processes the withdrawal without checking whether it is may have access to. They report all withdrawals to the IRS on Form 1099-SA. It is your responsibility to track what you spent the money on and report it correctly on your tax return.

If I am audited on an HSA withdrawal, how do I prove it was may have access to?

Bring receipts, invoices, or bank statements showing the date, provider, and amount. A letter from the provider describing the service also counts. If you cannot produce documentation, the IRS will treat the withdrawal as non-may have access to and assess tax and penalty. This is why keeping records is critical.

Can I appeal an HSA tax bill if I think the IRS made a mistake?

Yes. If you receive a bill for tax and penalty on an HSA withdrawal you believe was may have access to, you can file a Form 12203 (Request for Appeals Conference) or respond to the IRS notice with documentation of the may have access to expense. You have the right to dispute the assessment if you have proof the withdrawal was for a may have access to medical expense.
