Your FSA card covers medical expenses, not groceries or gas
Your Flexible Spending Account (FSA) card works like a debit card, but it only works at pharmacies, medical offices, and stores selling medical equipment. You cannot use it for food, toiletries, gym memberships, or anything else. The IRS sets a specific list of what counts as a medical expense, and the card's system is programmed to block purchases that fall outside it.
When you swipe your FSA card, the merchant's system checks whether the item is on the IRS-approved list. If it is not, the transaction declines — even if you are at a pharmacy buying both insulin and shampoo. You would need to pay for the shampoo separately with another payment method.
The money in your FSA is pre-tax dollars your employer set aside for you. That tax break comes with a rule: you can only spend it on things the IRS classifies as medical care. Breaking that rule means penalties and taxes owed back.
Key Takeaways
- FSA cards work only at pharmacies, doctor offices, and medical supply stores, and the card declines if you try to buy something not on the IRS medical list.
- Prescription medications, over-the-counter drugs with a prescription, medical equipment, and copays all count; food, cosmetics, and wellness items do not.
- Some items are ambiguous — like sunscreen or first aid kits — and whether they work depends on the reason you are buying them and the merchant's coding.
- If your card declines, you can pay out of pocket and request reimbursement from your FSA plan administrator with a receipt and proof the expense was medical.
- Unused FSA money does not roll over to next year; most plans have a grace period or let you carry forward a small amount, but rules vary by employer.
What the FSA card will approve
Prescription medications are always approved. So are over-the-counter drugs if you have a prescription from a doctor — this includes pain relievers, allergy medicine, cold medicine, and stomach remedies when prescribed. Without a prescription, over-the-counter drugs usually decline.
Medical equipment and supplies approved include blood glucose monitors, test strips, lancets, bandages, crutches, braces, heating pads, and compression sleeves. Copays and coinsurance at doctor visits, dental work, and vision care all count. Prescription glasses, contact lenses, and lens solution work. Mental health copays and therapy sessions covered by insurance are approved.
Dental work — fillings, cleanings, root canals, orthodontia — is approved. Hearing aids and batteries are approved. Prescription inhalers and EpiPens are approved. Fertility treatments, including some medications and procedures, are approved in most plans.
What the FSA card will decline
Cosmetics and personal care items decline, even at a pharmacy. This includes toothpaste, deodorant, shampoo, soap, lotion, and makeup. Vitamins and supplements decline unless they treat a specific medical condition and you have a doctor's letter saying so. General wellness items — gym memberships, fitness classes, diet programs — decline.
Food and beverages decline, including protein bars marketed as meal replacements and sports drinks. Sunscreen declines in most cases because it is considered cosmetic, not medical. Condoms decline. Pregnancy tests decline. Menstrual products decline. Wigs decline, even if prescribed for hair loss from medical treatment.
Over-the-counter medications without a prescription decline — this includes aspirin, ibuprofen, acetaminophen, antihistamines, and decongestants bought without a doctor's order. Pet medications decline. Childcare and babysitting decline. Massage therapy declines unless prescribed by a doctor for a specific medical condition.
The gray zone: items that sometimes work
Some purchases depend on context or how the merchant codes the item. Sunscreen might work if a dermatologist prescribes it for a skin condition. A first aid kit might work if you buy it at a medical supply store but decline at a drugstore, depending on how the store categorizes it. Elastic bandages, ace wraps, and athletic tape work at medical supply stores but may decline at sporting goods stores.
Orthopedic shoes work if prescribed by a doctor for a foot condition, but regular shoes decline. Maternity support belts work if prescribed. Seat cushions work if prescribed for a medical condition like sciatica. The rule is: if a doctor prescribed it or it is sold primarily as medical equipment, it is more likely to work.
When you are unsure, ask the merchant before you check out, or call your FSA plan administrator — the phone number is on the back of your card. They can tell you whether a specific item will work before you buy it.
What to do when your card declines
If your card declines at checkout, you have two options. You can pay out of pocket with another payment method and then request reimbursement from your FSA plan. You will need to submit the receipt and often a form from your doctor or the merchant stating the item was medically necessary.
The reimbursement process usually takes one to two weeks. You mail or upload the receipt and any required documentation to your plan administrator — check your plan's website or the card's customer service number for the submission portal. Some plans let you submit through a mobile app.
Keep all receipts for FSA purchases for at least three years. The IRS can audit FSA spending, and you need documentation to prove the money went to approved medical expenses.
How much you can spend and what happens to leftover money
The IRS sets an annual limit on how much you can put into an FSA. For 2024, that limit is $3,300 per person; for 2025, it is $3,300. Your employer may set a lower limit. You choose the amount when you enroll, usually once a year during open enrollment.
FSA money does not roll over to the next year — this is called the "use-it-or-lose-it" rule. However, many employers offer either a grace period (usually two and a half months into the next year to spend the previous year's money) or a carryover of up to $640 (for 2024 and 2025). Check your plan documents to see which option your employer offers.
Because of this rule, many people estimate conservatively and put in less than the maximum. If you think you will spend $2,000 on medical expenses next year, put in $2,000, not $3,300. Unused money is forfeited.
How to know what your specific plan covers
Your FSA plan is set up by your employer, and some employers add their own restrictions beyond what the IRS allows. Your plan documents — usually available on your employer's benefits website or from your HR department — list exactly what is and is not covered under your plan.
Call the customer service number on the back of your FSA card. The representatives can tell you whether a specific item or service will work before you buy it. This is faster than guessing and having your card decline.
Your plan administrator's website usually has a searchable database of approved items. Some plans publish a full list of approved and denied items. If you cannot find the answer, email your plan administrator with the item name and they will respond within a few business days.
Frequently Asked Questions
Can I use my FSA card to buy over-the-counter pain relievers?
Only if you have a prescription from a doctor. Without a prescription, over-the-counter pain relievers like ibuprofen and acetaminophen decline. If your doctor writes a prescription for over-the-counter medication, the pharmacy can fill it and your FSA card will work.
What happens if I use my FSA card for something that is not approved?
The transaction should decline at the point of sale. If it goes through by mistake, your plan administrator may ask you to repay the amount or it could be treated as a taxable distribution, meaning you owe income tax and possibly a penalty on that money.
Can I use my FSA card at any pharmacy?
Most major pharmacy chains and independent pharmacies accept FSA cards. Some smaller stores or online retailers may not have the system set up to process FSA payments. Call ahead or check the merchant's website if you are unsure.
Do I have to use my FSA card, or can I pay out of pocket and get reimbursed?
You can do either. Some people pay out of pocket and request reimbursement later, especially if they are unsure whether an item will be approved. Keep your receipt and submit it to your plan administrator with any required documentation.
Can I buy prescription glasses or contacts with my FSA card?
Yes. Prescription eyeglasses, contact lenses, and contact lens solution are all approved FSA expenses. Frames and lens coatings are also approved. Non-prescription sunglasses decline, but prescription sunglasses work.
