Your Free Guide to FSA and HSA Cards

What Are FSA and HSA Cards and How Do They Work?

FSA and HSA cards are debit-style payment cards that let you spend money set aside for medical expenses. FSA stands for Flexible Spending Account, and HSA stands for Health Savings Account. Both accounts let you put pre-tax dollars into a dedicated account throughout the year, then use a card to pay for qualified health costs without paying income tax on that money.

Think of it this way: if you normally earn $50,000 per year and contribute $2,500 to an FSA, you only pay income taxes on $47,500. That $2,500 you set aside is not taxed at all. The FSA or HSA card makes it simple to spend that money—you just swipe it like a regular debit card at the pharmacy, doctor's office, or medical supply store.

The main difference between FSA and HSA cards comes down to who can use them and what happens to unused money. FSAs are offered by employers and have a "use-it-or-lose-it" rule: money you don't spend by the end of the plan year generally goes away. HSAs are individual accounts that you can open yourself if you have a high-deductible health insurance plan. HSA money rolls over year after year and can build up over time.

According to the IRS, about 30 million Americans use FSAs, and approximately 29 million people have HSAs as of recent data. Both accounts can help reduce the amount you actually pay for medical care by letting you use pre-tax dollars. The card itself is just the tool that makes spending from these accounts convenient.

Practical Takeaway: FSA and HSA cards work like regular debit cards but draw from special accounts filled with pre-tax money reserved for medical expenses. Understanding the basic mechanics helps you use the card confidently throughout the year.

Understanding FSA Cards and How to Use Them

FSA cards give you direct access to your employer's Flexible Spending Account. When your company sets up an FSA, it lets workers decide how much money they want to set aside from their paychecks each year for medical expenses. That money goes into your FSA account, and you receive a card to spend it. The money deducted from your paycheck is not subject to federal income tax, Social Security tax, or Medicare tax, which means you save money on taxes.

For 2024, the IRS allows workers to contribute up to $3,300 per year to an FSA (this amount changes yearly). If you have a family, you and your spouse can each open separate FSAs if both of your employers offer them. The average FSA contribution is around $1,600 per year, according to industry data.

Using an FSA card is straightforward. You can use it at pharmacies, medical supply stores, doctor offices, dental clinics, and vision centers. The card checks automatically whether each purchase qualifies as an eligible medical expense. If you buy something that doesn't qualify—like toothpaste or vitamins (unless prescribed)—the transaction will be denied and you'll need to pay with another payment method.

One key rule to remember: FSAs typically follow the "use-it-or-lose-it" principle. Money you don't spend by December 31 (or a short grace period if your employer allows) cannot be carried to the next year. However, some employers allow a small carryover of up to $640 per year, so check your plan documents. This means you should think carefully about how much to contribute—don't contribute more than you think you'll actually spend on medical costs.

Common qualified expenses include copays, deductibles, prescription medications, glasses and contacts, dental work, hearing aids, and over-the-counter medications (if you get a prescription from a doctor). You can also use FSA funds for things like crutches, bandages, and medical equipment.

Practical Takeaway: Plan your FSA contribution based on what you actually spent on medical care in the previous year, keeping in mind the "use-it-or-lose-it" rule. Start using your card early in the year so you have time to spend the money or find ways to use it before December.

How HSA Cards Differ and What You Should Know

HSA cards work differently from FSA cards in several important ways. An HSA (Health Savings Account) is your own personal account that you control and own, not something an employer controls. You can open an HSA yourself if you have a high-deductible health plan (HDHP) as your insurance. For 2024, a high-deductible plan for individuals has a deductible of at least $1,600, and for families, at least $3,200.

The biggest advantage of an HSA over an FSA is that money rolls over. If you contribute $2,000 to your HSA in 2024 and only spend $800, you still have $1,200 in your account in 2025. Your HSA balance can grow indefinitely as you contribute and save. Over time, many people build up thousands of dollars in their HSAs for future medical needs.

For 2024, you can contribute up to $4,150 per year to an HSA if you have individual coverage, or up to $8,300 for family coverage. If your employer offers an HSA, they may contribute money to your account as well. Some employers contribute $500 to $1,000 per year to worker HSAs. The money in your HSA is yours—if you leave your job, you keep the account and the money in it.

HSA cards can be used at the same places as FSA cards: pharmacies, doctor offices, dentists, vision centers, and medical supply stores. The same rules about qualified expenses apply. However, one extra feature of HSAs is that if you're age 65 or older, you can withdraw money from your HSA for any reason without penalty, though you'll pay income tax on non-medical withdrawals. Before age 65, withdrawals for non-medical expenses cost you a 20% penalty plus income taxes.

Some people think of HSAs as long-term savings accounts for healthcare. You don't have to spend the money every year. You could let it build up for years and use it to pay for medical expenses in retirement, when healthcare costs often increase. According to Fidelity, a 65-year-old couple retiring in 2024 might need approximately $315,000 in today's dollars to cover healthcare expenses in retirement—an HSA can help prepare for that.

Practical Takeaway: HSA cards give you money that stays with you year after year, making them powerful long-term savings tools. If your employer offers an HDHP and HSA, opening one can help you build healthcare savings over time while getting immediate tax benefits.

Qualified Medical Expenses You Can Pay With Your Card

Both FSA and HSA cards can pay for a wide range of medical expenses. The IRS has specific rules about what counts as "qualified," so it's important to know what you can and cannot purchase with your card. According to IRS Publication 502, qualified medical expenses are health care costs that are primarily to alleviate or treat an illness or condition.

Here are common expenses you can pay for with FSA or HSA cards:

• Doctor visits and copays—visits to primary care doctors, specialists, urgent care, and emergency room services
• Prescription medications—any medication prescribed by a doctor, filled at a pharmacy
• Over-the-counter medications—pain relievers, cold medicines, allergy medication, and other OTC drugs if you have a doctor's prescription
• Dental care—cleanings, fillings, root canals, orthodontics, extractions, and dental exams
• Vision care—eye exams, glasses, contact lenses, solution, and eye surgery like LASIK
• Mental health treatment—psychiatrist and psychologist visits, therapy sessions, and related treatment
• Medical equipment—crutches, bandages, heating pads, blood pressure monitors, and glucose monitors
• Hospital and surgical expenses—inpatient care, surgical procedures, and related hospital fees
• Physical therapy and rehabilitation—treatment following injury or illness
• Hearing aids
