You cannot roll over FSA money — the funds you don't spend by the end of the year are forfeited

Flexible Spending Accounts operate under a use-it-or-lose-it rule. Any money you contribute but don't spend on may be able to access medical or dependent care expenses by the end of the plan year is gone. Your employer cannot return it to you, and you cannot move it to a savings account or another type of account.

The only exception is a grace period, which some employers offer. If your plan includes one, you get an extra 2.5 months after the plan year ends to spend down your remaining FSA balance. This is not a rollover — it is extra time to use the same money. If you still have funds after the grace period ends, those funds are forfeited.

Key Takeaways

  • FSA funds do not roll over to the next year under any circumstances; unspent money is forfeited at the end of the plan year.
  • A grace period, offered by some employers, gives you an additional 2.5 months to spend your FSA balance, but this is not a rollover.
  • You can carry over a maximum of $640 into the next plan year only if your employer offers a carryover option instead of a grace period, and only up to that amount.
  • To avoid losing money, track your FSA spending throughout the year and adjust your contributions during open enrollment.
  • If you leave your job, your FSA balance is forfeited when ready unless you have unused funds during an active grace period.

The $640 carryover option: what it actually is

Some employers offer a carryover option as an alternative to a grace period. Under this option, you can carry over up to $640 of unused FSA funds into the next plan year. This is the only way FSA money moves forward, and it is capped at that amount by federal law.

Your employer chooses whether to offer a carryover option, a grace period, both, or neither. You cannot choose between them — your plan design is set by your employer. Check your FSA plan documents or ask your benefits administrator which option your employer uses.

If your employer offers both a grace period and a carryover option, you typically use the grace period first. Any money left after the grace period ends can then be carried over, up to the $640 limit.

How the grace period works in practice

A grace period extends your spending window by 2.5 months after the plan year ends. If your plan year runs January through December, the grace period would run January 1 through March 15 of the following year. You can submit claims for expenses incurred during the grace period and draw from your previous year's FSA balance to pay them.

The grace period applies to the same types of expenses your FSA normally covers. For a medical FSA, that means doctor visits, prescriptions, dental work, and other may have access to medical expenses. For a dependent care FSA, it means daycare and after-school care costs.

If you have money left after the grace period ends, it is forfeited. There is no second chance, no rollover, and no way to recover it.

Why FSA money cannot roll over like other accounts

The use-it-or-lose-it rule exists because FSAs are tax-advantaged accounts. When you contribute to an FSA, that money comes out of your paycheck before taxes are calculated. This saves you money on federal income tax, Social Security tax, and Medicare tax. In exchange, the IRS requires that you actually use the money for may be able to access expenses — you cannot treat it as a savings account or a way to accumulate tax-free funds year after year.

This is different from a Health Savings Account (HSA), which does allow rollovers and can accumulate indefinitely. HSAs have stricter may be able to access rules and higher deductibles, but they offer this flexibility in exchange.

What happens to your FSA if you leave your job

If you terminate employment, your FSA balance is forfeited when ready. You lose access to any unspent funds, even if you are in the middle of a grace period. The only exception is if you are actively using the grace period — in that case, you may be able to submit claims for expenses incurred before your termination date, but this depends on your plan's rules.

If you are leaving a job and have FSA funds remaining, try to spend them on may be able to access expenses before your last day. Stock up on over-the-counter medications, contact lens solution, or other may be able to access items if you have time.

How to avoid losing FSA money

The best strategy is to estimate your medical and dependent care expenses carefully during open enrollment and contribute only what you expect to spend. Many people contribute too much and lose money at year-end.

Track your FSA spending throughout the year using your account's online portal or mobile app. Most FSA administrators provide real-time balance updates. By mid-year, you should have a clear picture of how much you have spent and how much you have left.

If you realize you will not spend your full balance, you can sometimes adjust your contribution during a may have access to life event — a change in dependent care costs, a change in health insurance, or a significant change in medical expenses. Open enrollment also gives you a chance to lower your contribution for the next year based on what you learned this year.

FSA carryover versus grace period: which is better

A grace period is generally more useful because it gives you 2.5 extra months to spend the money without any cap. A carryover option limits you to $640, which may not be enough if you have a large balance.

However, a carryover option is better if you consistently have leftover funds and want to preserve them. With a grace period alone, any money not spent by the important date is lost. With a carryover, you get a second chance in the next plan year.

The ideal situation is having both: a grace period to spend most of your balance, and a carryover option to preserve up to $640 if you still have funds left. But this depends entirely on what your employer offers.

Frequently Asked Questions

Can I move my FSA balance to an HSA?

No. FSA and HSA are separate accounts with different rules. You cannot transfer money between them. However, you can have both accounts at the same time if you are enrolled in a high-deductible health plan. You would contribute to each independently.

What if I have a medical emergency and need my FSA money after the plan year ends?

If your plan includes a grace period, you can submit claims for expenses incurred during that period. If there is no grace period and the plan year has ended, you cannot access the funds. This is why it is important to know whether your plan offers a grace period.

Can my employer give me the unused FSA money as a bonus or paycheck?

No. Federal law prohibits this. Unspent FSA funds must be forfeited or, if your plan allows, carried over up to $640. Your employer cannot convert them to cash or any other form of compensation.

Do I lose my FSA if I take unpaid leave or go on disability?

Your FSA continues as long as you remain employed and enrolled in the plan. If you take unpaid leave, your contributions typically pause, but your account remains active. If you are on disability, the rules depend on your employer's policy and whether you continue to be considered an active employee.

What counts as an may be able to access FSA expense I should spend money on before year-end?

may be able to access expenses include copays, deductibles, prescriptions, dental work, vision care, hearing aids, and over-the-counter medications (with a prescription). For dependent care FSAs, may be able to access expenses are daycare, preschool, and after-school care. Check your plan documents for the complete list, as some employers restrict certain items.
