FSA money can only be spent on medical expenses that the IRS allows, and the rules are strict enough that many common health purchases don't may have access to
Your FSA (Flexible Spending Account) holds pre-tax dollars, which means the IRS controls what you can spend it on. You cannot use FSA funds for groceries, gym memberships, over-the-counter vitamins, or most wellness products — even if they seem health-related. The IRS publishes a specific list of may have access to medical expenses, and if an expense is not on that list, your FSA will reject the claim or you will owe taxes plus a penalty if you spend the money anyway.
The key rule: the expense must be for diagnosis, treatment, or prevention of a disease or condition, and it must be prescribed or recommended by a doctor. A bottle of ibuprofen you buy yourself does not may have access to. Ibuprofen prescribed by a doctor for a specific condition might. The difference matters because your FSA administrator will ask for documentation — a receipt, a prescription, or a letter from your doctor — before they reimburse you.
Key Takeaways
- Prescription medications, copays, deductibles, and coinsurance all may have access to, but over-the-counter drugs do not unless prescribed by a doctor.
- Medical equipment like crutches, wheelchairs, and blood pressure monitors qualifies, but fitness trackers and general wellness devices do not.
- Dental work, vision care, and hearing aids are covered, but cosmetic procedures and teeth whitening are not.
- You must keep receipts and be ready to prove that an expense was medically necessary — your FSA administrator can ask for documentation months later.
- FSA money does not roll over to the next year, so you lose any balance you do not spend by December 31 (or your plan's run-out date).
Prescription medications and pharmacy purchases
Prescription drugs are the clearest FSA purchase. Any medication your doctor prescribes — antibiotics, blood pressure pills, inhalers, birth control — qualifies. You pay with your FSA debit card at the pharmacy, and the transaction goes through without question in most cases.
Over-the-counter drugs are the trap. Aspirin, cold medicine, allergy pills, and antacids do not may have access to unless a doctor writes a prescription for them. Some people think "over-the-counter" means "not covered," but the real rule is "not prescribed." If your doctor writes a prescription for ibuprofen because you have a documented injury, that prescription version qualifies. The same ibuprofen you buy without a prescription does not.
Insulin is an exception: it qualifies even without a new prescription each time you buy it, because the IRS treats it as a standing prescription. Epinephrine auto-injectors (EpiPens) also may have access to without a new prescription each refill.
Doctor visits, tests, and medical procedures
Copays and coinsurance for doctor visits, urgent care, and emergency room visits all may have access to. If your insurance plan requires you to pay $30 at the doctor's office, you can use your FSA card to cover it. The same applies to the portion of a bill your insurance does not cover (coinsurance) — if you owe $200 after insurance pays its share, FSA money covers it.
Deductibles also may have access to. If your plan has a $1,500 deductible and you have not met it yet, FSA money can go toward that deductible. Once you have paid the deductible, FSA covers your copays and coinsurance going forward.
Lab work, X-rays, MRI scans, and other diagnostic tests are covered. Preventive care like annual physicals and cancer screenings qualifies too. Mental health visits — therapy, psychiatry, counseling — are covered the same way as physical health visits.
Dental and vision care
Dental work qualifies broadly: cleanings, fillings, root canals, extractions, and crowns are all covered. Orthodontics (braces) qualifies. Dental implants may have access to. The one major exception is cosmetic dentistry — teeth whitening, veneers purely for appearance, and cosmetic bonding do not may have access to unless they are part of reconstructive work after an injury or disease.
Vision care includes eye exams, glasses, contact lenses, and contact lens solution. Laser eye surgery (LASIK) qualifies. Sunglasses do not, even if you need them for a medical condition, because the IRS does not treat them as medical devices.
Hearing aids and hearing aid batteries may have access to. Hearing tests may have access to. Cochlear implants may have access to.
Medical equipment and supplies
Crutches, wheelchairs, walkers, canes, and braces all may have access to. Blood pressure monitors, glucose meters, and thermometers may have access to. Bandages, gauze, and medical tape may have access to. Compression stockings may have access to if prescribed for a medical condition.
The line between medical equipment and general wellness is where mistakes happen. A fitness tracker does not may have access to, even if it monitors your heart rate. A CPAP machine for sleep apnea qualifies. A mattress does not may have access to, even if you bought it because of back pain. A back brace prescribed by a doctor qualifies.
Crutches and wheelchairs must be for a medical condition — you cannot buy them speculatively. Keep the receipt and any documentation from your doctor showing why you needed the equipment.
Medications and treatments that do not may have access to
Vitamins and supplements do not may have access to unless prescribed by a doctor for a specific deficiency or condition. A multivitamin you take for general health does not may have access to. Vitamin D prescribed because your doctor found you deficient might may have access to — check with your FSA administrator and bring the prescription.
Weight loss drugs and appetite suppressants do not may have access to unless prescribed for a diagnosed medical condition (not just weight loss for appearance). Cosmetic procedures — Botox, fillers, hair removal, tattoo removal — do not may have access to. Teeth whitening does not may have access to unless it is part of reconstructive dentistry.
Gym memberships, fitness classes, and personal training do not may have access to, even if your doctor recommends exercise. Massage therapy does not may have access to unless prescribed by a doctor for a specific injury or condition. Acupuncture does not may have access to unless prescribed by a doctor.
Sunscreen does not may have access to. Skincare products do not may have access to. Over-the-counter pain relievers, cold medicine, and allergy pills do not may have access to unless prescribed.
How to document and submit FSA claims
Most FSA debit cards work like regular debit cards at pharmacies and medical offices — you swipe, and the transaction is approved or denied based on the merchant category. Pharmacies and doctor offices are coded in a way that usually triggers automatic approval. You do not need to submit a receipt for these routine transactions.
For other expenses — medical equipment, out-of-pocket costs, or anything unusual — you will need to submit a claim. Your FSA plan provides a website or mobile app where you upload a receipt and a form explaining the expense. Some plans also accept paper claims by mail. The process usually takes one to two weeks.
Keep all receipts for at least three years. The IRS can audit FSA claims years after you make them, and your FSA administrator can ask you to prove that an expense was medically necessary. A receipt alone is usually enough, but for borderline expenses (like a back brace), a note from your doctor saying why you needed it strengthens your case.
If your FSA administrator denies a claim, you can appeal. Ask them in writing why the expense was denied and provide additional documentation if you have it. Some denials are final, but others are reversed with the right paperwork.
Planning your FSA spending before the year ends
FSA money does not roll over. Whatever you do not spend by December 31 (or your plan's end date, which varies by employer) is forfeited. This is the "use it or lose it" rule, and it applies to almost all FSA plans. A small number of plans allow a grace period (usually 2.5 months into the next year) or a carryover of up to $610 (the amount changes yearly), but most do not.
In November and December, review your FSA balance and plan how to spend it. Schedule dental work, eye exams, or other routine care you have been putting off. Stock up on prescription refills. Buy medical equipment you know you will need. If you have a high balance and no obvious medical expenses, talk to your doctor about preventive care or screenings you could do before year-end.
Do not spend FSA money on non-may have access to expenses just to use the balance. If you buy something that does not may have access to and your FSA administrator catches it, you will owe taxes on that money plus a 20% penalty. It is better to lose the balance than to face a tax bill.
Frequently Asked Questions
Can I use my FSA card at the grocery store to buy healthy food?
No. Groceries do not may have access to, even if they are organic or labeled as healthy. FSA money is for medical expenses only. The only exception is if your doctor prescribes a specific medical food for a diagnosed condition (like a special formula for an allergy), in which case you might be able to claim it — but this is rare and requires documentation.
Does my FSA cover over-the-counter pain relievers if I have a prescription for them?
Yes. If your doctor writes a prescription for ibuprofen, acetaminophen, or any other over-the-counter drug, the prescription version qualifies for FSA reimbursement. You will need to show the prescription to your pharmacy or FSA administrator. Without a prescription, over-the-counter drugs do not may have access to.
What happens if I spend FSA money on something that does not may have access to?
If you use your FSA debit card at a merchant that is not coded as medical, the transaction may be declined. If it goes through and your FSA administrator later reviews it, they will ask you to prove it was a may have access to expense. If you cannot, you will owe taxes on that amount plus a 20% penalty. It is better to ask your FSA administrator before you spend if you are unsure.
Can I use FSA money for my spouse's or child's medical expenses?
Yes, as long as they are your tax dependents or spouse. You can use your FSA to pay for their doctor visits, prescriptions, dental work, and other may have access to medical expenses. You do not need to be the one receiving the care.
What should I do with leftover FSA money in December?
Spend it on may have access to medical expenses before December 31. Schedule a dental cleaning, buy prescription refills, or purchase medical equipment you know you will need. If your plan allows a grace period or carryover, check your plan documents — but most plans do not. Any balance you do not spend is forfeited.
