No — your employer cannot refund unused FSA money to you. Federal law prohibits it. Any balance left in your Flexible Spending Account at the end of the plan year is forfeited to the plan under the "use it or lose it" rule.
A Flexible Spending Account (FSA) is designed so that money left unspent at the end of the plan year stays with the plan, not with you. This is a federal rule built into how FSAs work, not something your employer chose. The money does not roll over to next year, does not transfer to your paycheck, and does not come back as a refund. Once the plan year ends, any balance you did not spend on may have access to medical or dependent care expenses is forfeited.
The only exception is a small carryover amount — up to $640 in 2024 for medical FSAs (the limit changes yearly) — that some employers choose to allow. Even then, that money carries over to the next plan year; it is not refunded to you. Dependent care FSAs have no carryover option at all.
Key Takeaways
- FSA money you do not spend by the end of the plan year is forfeited to the plan — your employer cannot refund it to you because federal law prohibits it.
- A small carryover (up to $640 for medical FSAs in 2024) may be available if your employer's plan includes this feature, but the money still belongs to the plan and must be spent in the next year.
- Dependent care FSAs have no carryover option; any unused balance is lost at year-end.
- You can request a refund only if you made a mistake during enrollment or if you were charged for contributions you did not authorize.
Why FSA money cannot be refunded
The "use it or lose it" rule exists because FSAs are funded with pre-tax dollars. When you contribute to an FSA, that money is deducted from your paycheck before federal income tax is calculated. In exchange for that tax break, the IRS requires that FSA funds be spent only on may have access to expenses within the plan year. Money left over cannot be returned to you as a refund because doing so would let you keep the tax benefit on money you did not actually spend on medical or dependent care.
This rule applies to all FSAs, regardless of employer size or plan design. Your employer has no legal authority to refund unused FSA money to you, even if they want to. The money goes to the plan's general fund, where it typically offsets the plan's administrative costs or is redistributed among remaining participants.
Carryover options for medical FSAs only
Starting in 2014, the IRS allowed employers to offer a carryover feature for medical FSAs. If your employer's plan includes this option, you can carry over up to $640 (in 2024; this amount increases slightly most years) from one plan year to the next. However, this is still not a refund — the money remains in your FSA and must be spent on may have access to medical expenses in the following year.
Not all employers offer carryover. Check your plan documents or ask your benefits administrator whether your medical FSA includes this feature. If it does, you will usually see the carryover amount posted to your account in January or whenever your new plan year begins. Dependent care FSAs never have a carryover option; any unused balance is lost.
When you might get money back from your FSA
A refund is possible only in specific situations where you were charged incorrectly or enrolled by mistake. If you were deducted FSA contributions without your consent, or if you were enrolled in the wrong plan type, contact your benefits administrator or HR department immediately. They can investigate whether a refund is warranted and process it if the error is confirmed.
Another scenario is if you experience a may have access to life event — such as a divorce, birth, or loss of dependent care — that allows you to change your FSA election mid-year. If you reduce your contribution amount, you stop losing money going forward, but you do not recover what was already deducted. Some plans allow you to submit claims for expenses you incurred before the change to use up the remaining balance.
How to avoid losing FSA money
The best strategy is to estimate your medical or dependent care expenses carefully before you enroll. For medical FSAs, think about copays, deductibles, prescriptions, dental work, and vision care you expect to pay out of pocket in the coming year. For dependent care FSAs, calculate the cost of daycare, after-school programs, or summer camps. Be conservative — it is better to contribute less and have money left over than to contribute too much and forfeit it.
Keep receipts and invoices for all FSA-may be able to access expenses throughout the year. Many people forget about smaller expenses like over-the-counter medications, first aid supplies, or co-insurance amounts. Reviewing your records in November or December can help you identify expenses you have not yet claimed. Some FSA providers also allow you to submit claims for expenses incurred in December even if you submit them in January, so check your plan's deadline rules.
If you have a health savings account (HSA) instead of or in addition to an FSA, remember that HSAs do roll over year to year and can be invested. FSAs and HSAs have different rules, so do not assume they work the same way.
Requesting a refund for enrollment or billing errors
If you believe you were charged FSA contributions in error, start by contacting your employer's benefits or HR department. Provide documentation of the error — such as payroll records showing the deduction, your enrollment confirmation, or written proof that you did not authorize the contribution. Ask them to investigate and explain what happened.
If your employer cannot resolve it, contact your FSA plan administrator directly. The plan administrator's name and contact information should be on your FSA card or in your plan documents. Request a written explanation of the charges and ask whether a refund or credit is possible. Keep copies of all correspondence.
If the error involved a significant amount and your employer or plan administrator refuses to address it, you may file a complaint with your state's Department of Insurance or the U.S. Department of Labor. However, this process is slow, so try to resolve it directly with your employer first.
What to do with leftover FSA funds before year-end
If you have a balance remaining in your FSA with only weeks left in the plan year, you have a short window to spend it. Submit claims for any medical or dependent care expenses you have already paid out of pocket. If you need new glasses, dental work, or prescriptions, schedule appointments before the year ends and pay with your FSA card or submit the receipt for reimbursement.
Some FSA providers offer a grace period — usually 2.5 months into the new year — during which you can submit claims for expenses incurred in the previous plan year. Check your plan documents to see if this applies to you. If it does, you have a bit more time, but do not rely on it; submit claims as soon as you have the receipts.
If you truly cannot spend the remaining balance, accept that the money will be forfeited. Do not spend it on non-may have access to expenses just to use it up; that defeats the purpose of the tax savings and could trigger an audit if the plan administrator questions the claims.
Frequently Asked Questions
Can my employer give me the unused FSA money as a bonus or extra paycheck?
No. Federal law prohibits this. Any attempt to refund FSA money to you as pay would violate the tax rules that make FSAs possible. Your employer cannot convert the money into wages or any other form of compensation.
What if I leave my job mid-year with FSA money left in my account?
You lose the remaining balance. FSA funds are tied to your employment and your employer's plan. When you leave, your FSA account closes, and any unspent money is forfeited. You cannot take it with you or roll it into a new employer's FSA.
Can I get a refund if I did not use my dependent care FSA because my child started school?
No, but you may be able to reduce your contribution for the next plan year. A change in your child's school status is usually considered a may have access to life event, which allows you to change your FSA election outside the normal enrollment period. Contact your benefits administrator to request a mid-year change.
Is there any way to get my FSA money back if I did not spend it?
Not through a refund. Your only options are to submit claims for expenses you have already paid, use the carryover feature if your plan offers it, or accept the loss. The "use it or lose it" rule is built into FSA law and cannot be waived.
Do HSAs work the same way as FSAs with unused money?
No. Health Savings Accounts (HSAs) roll over year to year, and the money is yours to keep. You can invest it and let it grow. FSAs do not roll over (except for the small carryover some employers offer), and the money belongs to the plan, not to you. If you have a choice between an HSA and an FSA, the HSA's rollover feature is a significant advantage.
