What is a Flexible Spending Account?

An FSA (or flexible spending account) is an employer-sponsored healthcare benefit that allows employees to set aside up to $3,200 (2024) annually to cover the cost of qualified medical expenses. It’s a lot like a savings account but used for qualified health-related costs. FSAs work on an annual plan year basis and are funded through regular payroll deductions on a pre-tax basis.

These funds are subject to a use-it-or-lose-it rule, which means that any funds that are unspent by the end of each plan year are forfeited to the account holder’s employer. That means you lose your remaining money if you miss the deadline for spending it all, so always keep track (hint: we have deadline reminders). But some accounts might have a lifeline as employers have the option of offering one of two deadline extensions: the FSA Grace Period or the $640 rollover.

Quick overview: The FSA Grace Period gives account holders up to 2.5 months after the end of their plan year to spend their remaining FSA dollars, while the $640 rollover allows employees to move up to $640 into next year’s account — not a bad deal if your plan has one of these options!

But not all plans have them. To be 100% sure about when you need to use your money, ask your HR department to give you more specifics about the plan.

What are the benefits of an FSA?

The key benefit of an FSA is that it withholds a portion of your taxable income, which is deposited tax-free into an account you can use to cover thousands of qualified medical expenses.

For instance, a household making the median U.S. household income of $74,580 that elects the full FSA contribution for 2024 ($3,200) would save about $1,000 in payroll taxes over the course of the year.

These tax-free funds can help you cover thousands of expenses you would usually pay for out-of-pocket. And they aren't limited to the account holder's personal medical expenses—you can also cover medical expenses for your spouse and qualifying dependents (children up to age 26 and adult dependents listed on your tax return).

But where FSAs really shine is in their ability to cover thousands of medical products and services.

What can I use my FSA for?

Short answer? A wide (and growing) selection of health and wellness products, ranging from things you probably use everyday, to highly specific diagnostic and treatment products. Pain relief products, baby health care essentials, healthy travel must-haves, you name it—if you have a medical need, chances are there’s some way you can benefit from an FSA.

Our comprehensive Eligibility List is a great place to learn exactly what is (and isn’t) FSA eligible.

What makes a product or service FSA eligible?

Let’s get a little technical here. The FSA eligibility of a product or service depends on whether it falls within the Internal Revenue Service’s (IRS) definition of “medical care.” This explanation has the catchy title of IRS Tax Code 213(d). But for our purposes, just know this:

“The term 'medical care' means amounts paid for the diagnosis, cure, mitigation, treatment, or prevention of disease, or for the purpose of affecting any structure or function of the body.”

Alright, so now that the official definition is out there, let’s look at some products or services that fall into that definition. With 2,500+ eligible products on our site alone, there’s obviously too many to list here (but not here) so for a quick overview, FSA funds can be used for:

Is an FSA worth it?

Today, managing an FSA is easier than ever. Most accounts provide online benefits portals to handle every aspect of account management, offer FSA cards to cover qualified health expenses at the point of sale, and can cover thousands of eligible medical products and services.

Dependent Care FSA

Aside from Health Care FSAs, there is also a Dependent Care FSA. The Dependent Care FSA, or DCAP or DCA, allows employees to set aside tax-free money toward dependent care costs. These costs could be toward daycare, care for elderly or disabled tax dependents, or toward before- and after-school care, to name a few. In order to qualify for a Dependent Care FSA, you and your spouse must be employed, searching for work, or attending school full-time. You can contribute $5,000 per household, or $2,500 if married and filing separately, to a Dependent Care FSA. Dependents include children up to age 13; your tax-dependent spouse or qualifying child; or relative who is incapable of self-care (mentally or physically).

Limited Purpose FSA

A Limited Purpose FSA is a type of FSA that only covers certain expenses that typically include vision, dental, or OTC dental and vision products. The employer limits the available expenses. A Limited Purpose FSA is often designed to be compatible with a Health Savings Account.
