You can use HSA funds for medical expenses you pay out of pocket, but the list is narrower than most people think

A Health Savings Account lets you spend pre-tax money on may have access to medical expenses. The IRS publishes a specific list of what counts, and it includes obvious things like doctor visits and prescriptions—but also some surprises like dental work, vision care, and certain over-the-counter items. The catch: if you spend HSA money on something that isn't on the IRS list, you owe income tax on that amount plus a 20% penalty.

The expenses have to be for you, your spouse, or your dependents. You cannot use HSA funds to pay for someone else's medical care, even if you're helping them out. And the expense has to be incurred after you open the account—you cannot retroactively reimburse yourself for medical bills from before your HSA existed.

Key Takeaways

  • Doctor visits, hospital stays, prescription drugs, and dental and vision care are all may have access to HSA expenses.
  • Many over-the-counter items count—including pain relievers, allergy medicine, and first-aid supplies—but only if you have a prescription or doctor's note for them.
  • Cosmetic procedures, gym memberships, and general wellness products do not count, even if they improve your health.
  • You can withdraw HSA money tax-free only for may have access to medical expenses; non-may have access to withdrawals trigger income tax plus a 20% penalty.
  • Keep receipts and documentation for every HSA withdrawal in case the IRS asks you to prove the expense was may have access to.

Doctor visits, hospital care, and prescription drugs

Copays, coinsurance, and deductibles for doctor visits all count as may have access to expenses. So do hospital stays, emergency room visits, and urgent care. If your insurance plan requires you to pay part of the bill, HSA money covers your share.

Prescription medications are always may have access to. Over-the-counter drugs are may have access to only if a doctor prescribes or recommends them in writing—a verbal suggestion does not count. For example, if your doctor writes a prescription for ibuprofen or an antihistamine, you can use HSA funds. If you buy the same product off the shelf without that documentation, you cannot.

Mental health treatment, including therapy and psychiatric medications, is covered. So are lab tests, X-rays, and diagnostic imaging ordered by a doctor.

Dental, vision, and hearing care

Dental work is a major may have access to expense category. This includes cleanings, fillings, root canals, crowns, extractions, and orthodontia like braces. Dental insurance copays and deductibles count too. If you pay out of pocket for dental work, HSA funds cover the full cost.

Vision care includes eye exams, glasses, contact lenses, and contact lens solution. Laser eye surgery (LASIK and PRK) is may have access to. Hearing aids and hearing tests are covered as well.

Over-the-counter items and medical supplies

Many over-the-counter products count as may have access to expenses, but only with a prescription or written doctor's note. Pain relievers, allergy medicine, cold medicine, antacids, and anti-diarrheal medication all may have access to if documented. Bandages, gauze, thermometers, blood pressure monitors, and glucose meters are may have access to without a prescription because they are medical devices, not drugs.

Crutches, wheelchairs, walkers, and other mobility aids are may have access to. Heating pads and ice packs count. Pregnancy tests and contraceptives are may have access to. Sunscreen does not count—it is considered a cosmetic or general wellness product, not a medical treatment.

What does not count as a may have access to expense

Cosmetic procedures are not may have access to, even if they are performed by a doctor. Botox, teeth whitening, hair removal, and elective plastic surgery do not count. The exception is cosmetic surgery to repair an injury or birth defect, which is considered reconstructive rather than cosmetic.

Gym memberships, fitness classes, and general wellness programs are not may have access to, even if your doctor recommends exercise. Weight loss programs and diet supplements do not count. Vitamins and nutritional supplements are not may have access to unless prescribed by a doctor for a specific medical condition.

Insurance premiums themselves are not may have access to HSA expenses—you cannot use HSA money to pay your monthly health insurance bill. The exception is COBRA continuation coverage and long-term care insurance premiums, which are may have access to in limited circumstances.

Childcare, maternity clothes, and baby products are not may have access to. Travel to receive medical care is not may have access to, even if the trip is necessary. Marijuana, even in states where it is legal, is not a may have access to expense under federal tax law.

How to document and track your spending

Keep receipts and invoices for every HSA withdrawal. The IRS does not require you to submit documentation when you withdraw money, but you must be able to prove the expense was may have access to if you are audited. A receipt showing the date, amount, and what was purchased is the standard proof.

For prescription medications and over-the-counter drugs that require a prescription, keep the prescription itself or a letter from your doctor stating the medical reason. For medical devices and supplies, the receipt is usually enough if it clearly describes the item.

Some HSA providers offer a debit card that you can use at pharmacies and medical providers. When you swipe the card, the provider may ask you to categorize the expense. Answer accurately—if you misclassify a non-may have access to expense as may have access to, you are still liable for the tax and penalty if audited.

What happens if you spend HSA money on a non-may have access to expense

If you withdraw HSA funds for something that is not on the IRS list, you owe income tax on that amount at your ordinary tax rate, plus a 20% penalty. For example, if you withdraw $500 for a non-may have access to expense and you are in the 22% tax bracket, you owe $110 in income tax plus $100 in penalty—$210 total on top of the $500 you already spent.

After age 65, the penalty goes away. You still owe income tax on non-may have access to withdrawals, but not the 20% penalty. This makes HSA a useful retirement savings tool if you have money left over after paying medical expenses.

The HSA provider does not automatically catch non-may have access to expenses. It is your responsibility to track what you spend and report it correctly on your tax return. If the IRS audits you and finds non-may have access to withdrawals, you will owe back taxes, penalties, and interest.

Frequently Asked Questions

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

Yes, if your spouse is covered under your health plan or if you file taxes jointly. You can use HSA funds for your spouse's doctor visits, prescriptions, dental work, and other may have access to medical expenses. You cannot use HSA funds for a dependent's expenses if that dependent is not claimed on your tax return.

Is a prescription required for all over-the-counter medications?

A prescription or written doctor's note is required for over-the-counter drugs like pain relievers and allergy medicine. Medical supplies like bandages and thermometers do not need a prescription because they are classified as devices, not drugs. When in doubt, ask your doctor to document the recommendation in writing.

Can I use HSA money for my gym membership if my doctor recommends exercise?

No. Gym memberships and fitness classes are not may have access to expenses, even with a doctor's recommendation. The IRS treats them as general wellness, not medical treatment. If your doctor prescribes physical therapy for an injury, that is may have access to—but a gym membership is not.

What if I accidentally spend HSA money on something non-may have access to?

You owe income tax plus a 20% penalty on the non-may have access to amount. Report it on your tax return in the year you withdrew it. If you catch the mistake before filing, you can redeposit the money into your HSA within a certain timeframe, though rules vary by provider—contact your HSA administrator immediately.

Can I use my HSA after I turn 65?

Yes. After 65, you can withdraw HSA money for any reason without the 20% penalty, though non-medical withdrawals are still subject to income tax. Many people use HSA as a retirement savings account because the money rolls over year to year and grows tax-free if invested.
