FSAFEDS is not a health savings account — it's a different type of account called a flexible spending account
FSAFEDS (the Federal Employees Health Benefits Program Flexible Spending Account) and an HSA are both accounts that let you set aside pre-tax money for medical costs, but they work differently and have different rules. The biggest difference: an HSA is a savings account you own and keep forever, while FSAFEDS is a spending account tied to your job that you lose if you leave federal employment. FSAFEDS also has a "use it or lose it" rule — money you don't spend by the end of the year is gone, whereas HSA money rolls over indefinitely.
If you're a federal employee, you may have access to FSAFEDS through your benefits package. If you're not a federal employee, FSAFEDS is not available to you. This guide explains how FSAFEDS works and how it differs from an HSA so you can understand which account type you have or might have access to.
Key Takeaways
- FSAFEDS is a flexible spending account for federal employees only, while HSAs are available to anyone enrolled in a high-deductible health plan through any employer or the individual market.
- FSAFEDS money must be spent within the plan year or you lose it, but HSA money stays in your account indefinitely and grows tax-free.
- FSAFEDS contributions come directly from your paycheck before taxes, just like HSA contributions, but FSAFEDS is managed by the federal government for federal workers.
- You can have both an FSAFEDS account and an HSA at the same time if you meet the requirements for each, though the rules about what you can spend them on overlap.
- If you leave federal employment, you lose access to FSAFEDS, but any HSA you have belongs to you and moves with you to your next job or into retirement.
How FSAFEDS works and who can use it
FSAFEDS is a benefit offered only to federal employees and retirees through the Federal Employees Health Benefits Program (FEHBP). You enroll during the federal benefits open season, usually in November, and the money you choose to set aside comes out of your paycheck before federal income tax is calculated. For 2024, federal employees can set aside up to $3,300 per year in an FSAFEDS account, though this amount may change year to year.
You use FSAFEDS money to pay for out-of-pocket medical, dental, and vision costs that your health plan doesn't cover — things like copays, deductibles, and procedures your insurance won't pay for. You submit receipts and claims to the FSAFEDS administrator (usually a third-party company hired by the federal government) and they reimburse you from your account. The money comes from your own contributions, not from your employer or the government.
If you are not a federal employee or retiree, you cannot open an FSAFEDS account. You may have access to a similar account called a Dependent Care FSA (for childcare costs) or a regular FSA through a private employer, but those are different programs with different rules.
The "use it or lose it" rule and how it differs from HSAs
The most important difference between FSAFEDS and an HSA is what happens to money you don't spend. With FSAFEDS, if you don't use the money in your account by the end of the plan year (usually December 31), you lose it. There is a grace period of up to 2.5 months into the next year in some cases, but any money left after that is forfeited. This is called the "use it or lose it" rule, and it's built into how FSAs work.
An HSA has no use-it-or-lose-it rule. Money you contribute stays in your account and earns interest or investment returns. You can let it grow for years and spend it whenever you need to, even in retirement. This makes HSAs much more flexible for long-term savings, while FSAFEDS is designed for spending money you know you'll need within the current year.
Because of this difference, FSAFEDS works best if you have predictable medical costs you know you'll incur — regular prescriptions, ongoing therapy, dental work you've already scheduled. If your medical costs are unpredictable or you want to save for future healthcare, an HSA is a better fit.
Can you have both FSAFEDS and an HSA at the same time?
Yes, you can have both accounts open at the same time if you meet the requirements for each. However, there are limits on how much you can contribute to each, and the rules about what you can spend them on overlap.
If you have FSAFEDS and an HSA, you can use each account to pay for different expenses, or you can use one account for some costs and the other for others. For example, you might use FSAFEDS for your regular copays and deductibles, and use your HSA to save for larger medical costs or future healthcare. Just keep careful records of which account you're using for which expense, because you cannot claim the same expense twice.
The main reason to have both is that FSAFEDS has a lower contribution limit and a use-it-or-lose-it important date, while an HSA lets you save larger amounts over time. If you're a federal employee with access to FSAFEDS and you also have a high-deductible health plan that qualifies for an HSA, it may make sense to use FSAFEDS for predictable costs and HSA for savings.
What happens to FSAFEDS when you leave federal employment
When you leave a federal job, you lose access to FSAFEDS when ready. Any money left in your account at the time you leave is forfeited — you cannot take it with you or roll it over to another account. This is one of the biggest disadvantages of FSAFEDS compared to an HSA: the account is tied to your employment, not to you.
If you have an HSA through a federal employee health plan, that account is yours to keep. You own it, and it moves with you to your next job, to the individual insurance market, or into retirement. You can continue to use it to pay for medical costs for the rest of your life.
Before you leave federal employment, it's worth spending down your FSAFEDS balance if you can, since any remaining money will be lost. You might schedule dental work, vision exams, or other planned medical care in the weeks before your last day to use up the balance.
How FSAFEDS contributions and reimbursement work
When you enroll in FSAFEDS during the federal benefits open season, you decide how much to contribute for the year. This amount is divided by the number of pay periods remaining in the year, and that amount is deducted from each paycheck before federal income tax is calculated. This reduces your taxable income, which is why contributing to FSAFEDS saves you money on taxes.
To get reimbursed, you submit a claim form and receipts or an explanation of benefits (EOB) from your insurance company to the FSAFEDS administrator. The administrator reviews the claim to make sure the expense is covered under FSAFEDS rules, and if it is, they reimburse you from your account balance. Some FSAFEDS accounts come with a debit card that you can use at the point of sale, which speeds up the process and eliminates the need to submit receipts for every small purchase.
The reimbursement process typically takes one to two weeks, though it can be faster if you use a debit card. Keep all receipts and documentation for at least three years in case the administrator asks for proof of an expense.

Frequently Asked Questions
Can I use FSAFEDS money to pay for my spouse's or children's medical costs?
Yes. FSAFEDS money can be used for may have access to medical costs for you, your spouse, and your dependents, as long as you claim them on your federal tax return. The money doesn't have to be spent only on your own healthcare.
What happens if I don't spend all my FSAFEDS money by the end of the year?
You lose it. FSAFEDS has a strict use-it-or-lose-it rule. Some plans offer a grace period of up to 2.5 months into the next year, but after that, any remaining balance is forfeited. Check your plan documents to see if your FSAFEDS account has a grace period.
Can I change my FSAFEDS contribution amount during the year?
No, not unless you have a may have access to life event — such as a change in your health plan, birth of a child, marriage, or divorce. Outside of open season and may have access to events, your contribution amount is locked in for the year.
Is FSAFEDS the same as a Health Savings Account?
No. FSAFEDS is a flexible spending account, which is a different type of account. The main differences are that FSAFEDS has a use-it-or-lose-it rule, is only for federal employees, and is tied to your job. HSAs have no use-it-or-lose-it rule, are available to anyone with a high-deductible plan, and belong to you permanently.
Can I roll over unused FSAFEDS money to an HSA?
No. FSAFEDS money cannot be rolled over or transferred to an HSA or any other account. If you leave federal employment or don't spend your FSAFEDS balance by the end of the year, that money is lost.
