What an HSA covers and what it doesn't

You can use your HSA to pay for medical expenses that your health insurance does not cover, but only those that the IRS has approved. The IRS publishes a list of may have access to medical expenses, and if an expense is not on that list, you cannot use HSA money for it without owing taxes and a penalty on the withdrawal.

may have access to expenses include doctor visits, hospital stays, prescription drugs, dental work, vision care, mental health treatment, and medical equipment like wheelchairs or hearing aids. They also include some over-the-counter items—but only if you have a prescription for them. For example, you can buy aspirin with HSA money if your doctor writes a prescription, but you cannot buy it off the shelf without one.

You cannot use HSA money for health insurance premiums (with three exceptions: COBRA continuation coverage, Medicare premiums, and long-term care insurance). You also cannot use it for cosmetic procedures, gym memberships, vitamins, or anything the IRS classifies as general wellness rather than treatment of a specific condition.

Key Takeaways

  • The IRS maintains a specific list of may have access to medical expenses, and using HSA money for anything outside that list triggers taxes and a 20% penalty on the amount withdrawn.
  • Over-the-counter medications and supplies require a prescription from your doctor to be paid for with HSA funds, even if they are sold without one at the pharmacy.
  • You can use your HSA to pay for dental and vision care, mental health treatment, and medical equipment, but not for cosmetic procedures or general wellness products.
  • If you withdraw HSA money for a non-may have access to expense before age 65, you owe income tax plus a 20% penalty; after 65, you owe only income tax.

How to pay for medical expenses with your HSA

Most HSAs come with a debit card that you can use at the pharmacy, doctor's office, or hospital. When you swipe it, the transaction is recorded and the money comes directly from your HSA balance. This is the fastest way to pay and requires no paperwork at the time of purchase.

If you do not have a debit card, or if the provider does not accept it, you can pay out of pocket and then request reimbursement from your HSA administrator. You will need to submit a receipt or invoice showing the date, amount, and type of expense. The reimbursement usually arrives within one to two weeks, though some administrators are slower.

Keep all receipts and medical bills for at least three years. The IRS can audit your HSA and ask you to prove that the money you withdrew was spent on may have access to expenses. If you cannot show documentation, the IRS will treat the withdrawal as non-may have access to and assess taxes and penalties retroactively.

Non-may have access to withdrawals and what they cost

If you use HSA money for something that is not on the IRS list, you owe income tax on the amount withdrawn, plus a 20% penalty. This penalty applies only to the non-may have access to portion of the withdrawal, not to your entire HSA balance.

For example, if you withdraw $500 to pay for a cosmetic procedure, you owe income tax on that $500 (at your marginal tax rate) plus $100 in penalties. If your tax bracket is 22%, you would owe $110 in tax plus $100 in penalties, for a total of $210 out of the $500 you withdrew. That leaves you $290 to pay for the procedure, and you have lost $210 to taxes and penalties.

After age 65, the 20% penalty goes away, but you still owe income tax on non-may have access to withdrawals. This makes an HSA a useful retirement savings tool if you do not spend all the money on medical expenses while you are working.

Using your HSA for family members and dependents

You can use your HSA to pay for the medical expenses of your spouse and any dependent children, even if they are not covered by your health insurance plan. You do not need to be the one receiving the treatment—the expense just needs to be for someone you can claim as a dependent on your tax return.

This applies to dental and vision care as well. If your child needs braces or your spouse needs glasses, you can pay for those with your HSA. The same rules about may have access to expenses and documentation apply: you need receipts, and the expense must be on the IRS list.

If you have a dependent adult child or parent living with you, you may also be able to use HSA money for their medical expenses, depending on whether you can claim them as a dependent. Check your specific tax situation or ask your HSA administrator if you are unsure.

Common expenses people try to pay for and get wrong

Over-the-counter pain relievers, allergy medicine, and cold medicine are may have access to expenses only if you have a prescription. Many people buy these at the pharmacy without a prescription and then try to reimburse themselves from their HSA, which triggers an audit flag. If you use these regularly, ask your doctor for a prescription so you can use HSA money without penalty.

Sunscreen, toothpaste, and other personal hygiene products are not may have access to, even if they prevent health problems. Vitamins and supplements are also not may have access to unless they treat a specific diagnosed condition and your doctor prescribes them. Protein powder, meal replacement shakes, and other nutritional products fall into the same category: not may have access to, even if they are medically necessary for weight loss or recovery.

Gym memberships and fitness classes are not may have access to, even if your doctor recommends exercise. However, if you have a specific condition like cardiac rehabilitation after a heart attack, and your doctor prescribes a medically supervised program, that program may be may have access to. The key is that it must be treatment of a diagnosed condition, not general wellness.

Cosmetic procedures—including teeth whitening, Botox, and elective surgery—are not may have access to. However, if the procedure is medically necessary (for example, reconstructive surgery after an accident or to correct a breathing problem), it may be may have access to. You will need documentation from your doctor stating that the procedure is medically necessary, not cosmetic.

What happens if you use your HSA incorrectly

If you withdraw money for a non-may have access to expense, you have until the tax filing deadline to correct the mistake. You can redeposit the money into your HSA, and if you do so before you file your taxes, you can avoid the penalty. However, you still owe income tax on the amount, and you must report the correction on your tax return.

If you do not correct the mistake before filing, the IRS will assess the 20% penalty when they process your return or if they audit you later. If you are audited and cannot produce receipts for the expenses you claimed, the IRS will treat all of those withdrawals as non-may have access to and assess penalties on the entire amount.

Some HSA administrators flag suspicious transactions automatically. If you try to use your debit card for something that does not look like a medical expense—for example, at a grocery store or gas station—the transaction may be declined or flagged for review. This is a built-in safeguard to prevent accidental misuse.

Frequently Asked Questions

Can I use my HSA to pay for my health insurance deductible?

What if my doctor says I need something but my insurance won't cover it?

If the expense is on the IRS list of may have access to medical expenses, you can use your HSA to pay for it, regardless of whether your insurance covers it. You will need documentation from your doctor showing that it is medically necessary. If the expense is not on the IRS list, HSA money cannot be used.

Can I use my HSA to pay for my spouse's medical expenses if they are not on my health plan?

Yes, as long as you can claim your spouse as a dependent on your tax return. You do not need to be enrolled in the same health insurance plan. Keep receipts showing the expense and your spouse's name.

Do I have to spend my HSA money every year or do I lose it?

No. Unlike a flexible spending account (FSA), an HSA does not have a "use it or lose it" rule. Money rolls over from year to year and stays in your account indefinitely. You can accumulate it and use it whenever you have a may have access to medical expense.

What if I use my HSA debit card by mistake for something that is not may have access to?

Contact your HSA administrator immediately and ask them to reverse the transaction. If they reverse it before you file your taxes, you can avoid the penalty. If the reversal happens after you file, you may need to file an amended return to correct the error.
