What Is Flexible Savings Account?

A Flexible Spending Account, often called an FSA, is a tax-advantaged account you set up through your employer. It lets you set aside pre-tax money from your paycheck to pay for eligible medical expenses, and in some cases, dependent care costs. The main benefit is that you reduce your taxable income, which means you pay less in taxes overall and effectively get a discount on your health care expenses.

Think of it as a dedicated wallet for health costs. You decide at the start of the year how much to contribute. That money is deducted from your pay before taxes are taken out. When you need to pay for a doctor’s visit, a prescription, or new glasses, you use those funds. The trade-off is that most FSAs are “use it or lose it,” meaning you must spend the money within the plan year or lose what remains.

What Is Flexible Savings Account and How Does It Work?

An FSA is a benefit offered by many employers as part of their benefits package. You enroll during open enrollment, typically in the fall, and choose an annual contribution amount. This amount is divided evenly across your paychecks for the year.

The money is taken out of your paycheck before federal, state, and Social Security taxes are calculated. This lowers your taxable income. For example, if you earn $50,000 and contribute $2,000 to an FSA, you are only taxed on $48,000. The savings come from not paying income tax or payroll tax on that $2,000.

You then use the funds to pay for qualified medical expenses. These expenses include things like copays, deductibles, prescription drugs, and medical supplies. You can also use the funds for many over-the-counter items, such as pain relievers and cold medicine, though the rules have changed over the years and now generally require a prescription for some items.

Many plans provide a debit card linked to your FSA. You can swipe it at the pharmacy or doctor’s office, and the funds are drawn directly from your account. Some expenses may require you to submit a claim form and a receipt for reimbursement.

What Can You Buy With an FSA?

The IRS defines what counts as an eligible medical expense. The list is long and covers most things a doctor would recommend. Common eligible expenses include doctor visits, hospital care, dental treatments, vision care, and mental health counseling.

Prescription medications are covered. So are many over-the-counter drugs. Since 2020, you can use FSA funds for over-the-counter medicines without a prescription. This includes pain relievers, allergy medication, and cough syrup. You can also buy menstrual care products, which became eligible in 2020.

Medical equipment and supplies are covered as well. This includes items like blood pressure monitors, crutches, bandages, and diagnostic tests. Some readers, contact lens solution, and sunscreen are also eligible.

There are important exclusions. You cannot use FSA funds for cosmetic procedures, most cosmetic surgery, or items that are only for general health, like most vitamins and supplements. You also cannot use the funds to pay for health insurance premiums, though there are limited exceptions for certain plans.

A note on dental and vision: these are commonly covered. Braces, teeth whitening prescribed by a dentist, eyeglasses, contact lenses, and LASIK surgery are all eligible. If you wear glasses or contacts, an FSA can be a practical way to reduce the cost.

What Are the Different Types of FSAs?

There are two main types of FSAs, and it helps to know which one your employer offers. The most common is a health care FSA. This covers medical, dental, and vision expenses as described above.

The second type is a dependent care FSA. This account covers child care and elder care expenses. You can use it to pay for daycare, preschool, summer camp, and care for an elderly dependent who lives with you. The rules are different from a health care FSA. The money is still pre-tax, but the eligible expenses are limited to care that allows you and your spouse to work or attend school.

A dependent care FSA has a separate contribution limit from a health care FSA. You can contribute to both in the same year. The funds in a dependent care FSA are also subject to a “use it or lose it” rule, though the grace period rules may differ.

Some employers offer a limited-purpose FSA. This type is designed for people who have a high-deductible health plan with a Health Savings Account, or HSA. A limited-purpose FSA only covers dental and vision expenses until you meet your deductible. After that, it can cover other medical costs. This type of FSA allows you to save for dental and vision care without interfering with your HSA eligibility.

How Much Can You Contribute to an FSA?

The IRS sets annual contribution limits for FSAs. These limits can change each year to account for inflation. For health care FSAs, the limit has been around $3,000 to $3,200 in recent years. For dependent care FSAs, the limit is higher, typically around $5,000 per household.

Your employer may set a lower limit than the IRS maximum. Some employers cap health care FSA contributions at $2,500 or $2,000. You can only contribute the amount your employer allows, up to the IRS limit.

It is important to be realistic when choosing your contribution amount. If you contribute too much, you risk losing money at the end of the year. If you contribute too little, you miss out on tax savings. A good approach is to review your spending from the previous year on prescriptions, copays, and dental work, and use that as a starting point.

What Happens to Unused FSA Money at the End of the Year?

This is the most important rule to understand. Most FSAs are “use it or lose it.” Any money left in your account after the plan year ends is forfeited to your employer. You do not get it back.

There are two options that can help you avoid losing money. The first is a grace period. Some employers offer a grace period of up to 2.5 months after the plan year ends. During this time, you can still spend the previous year’s funds on eligible expenses. For example, if your plan year ends on December 31, you might have until March 15 to use the remaining money.

The second option is a carryover. Some employers allow you to carry over up to a certain amount into the next plan year. The IRS allows a carryover of up to $610 for health care FSAs, though your employer may set a lower amount. This money does not count against your next year’s contribution limit.

Your employer chooses whether to offer a grace period, a carryover, or neither. They cannot offer both in the same plan year. This is a key detail to check when you enroll. If your employer offers neither, you need to plan your spending carefully.

FSA vs. HSA: What Is the Difference?

People often confuse FSAs with Health Savings Accounts, or HSAs. They are similar in that both offer tax advantages for medical expenses, but they are quite different in practice.

An HSA is only available if you have a high-deductible health plan. The money you contribute is pre-tax, and it rolls over from year to year. There is no “use it or lose it” rule. The money is yours to keep, even if you leave your job. An HSA is often described as a retirement account for health expenses because the funds can grow tax-free over time.

An FSA is tied to your employer. You generally lose the account if you change jobs. The funds do not roll over, and you cannot invest them. The main advantage of an FSA is that you can use it with any type of health plan, not just a high-deductible one.

You cannot have both a health care FSA and an HSA at the same time, with one exception. A limited-purpose FSA that only covers dental and vision does not disqualify you from contributing to an HSA. This is a useful combination for people who want to save for dental work while building an HSA.

Is an FSA Right for You?

An FSA makes sense if you have predictable medical expenses. If you know you will need glasses, have regular prescriptions, or have planned dental work, the tax savings are real. You are essentially paying for these expenses with pre-tax dollars, which can save you 20 to 40 percent depending on your tax bracket.

An FSA is a poor fit if you cannot predict your spending. If you rarely visit the doctor and have no regular prescriptions, you may struggle to use the funds before the deadline. The risk of losing money at the end of the year may outweigh the tax benefit.

Be honest with yourself about your spending habits. The money in an FSA is not a savings account. It is a spending account with a deadline. If you are disciplined about using the funds, it is one of the simplest ways to reduce your health care costs.

One practical tip: if you have a health care FSA, schedule appointments and buy supplies early in the plan year. Do not wait until December. Pharmacies and clinics get busy at year-end, and you do not want to lose money because you ran out of time.
