Flexible spending accounts do not roll over—money you don't spend by the end of the plan year is forfeited

Flexible spending accounts (FSAs) operate under a "use-it-or-lose-it" rule set by the IRS. Any balance remaining in your FSA on December 31 (or your plan year's final day) cannot be carried into the next year. The money reverts to your employer, and you lose access to it. This is the core difference between FSAs and other retirement or health savings accounts: FSAs have no rollover option, no exceptions, and no way to recover unspent funds once the plan year ends.

The only partial exception is a grace period, which some employers offer. If your plan includes a grace period, you get an extra 2.5 months (typically through March 15) to spend money from the prior year. Not all employers offer this, and it is optional on their part. Even with a grace period, any money still unspent after that deadline is gone.

Key Takeaways

  • FSA balances do not roll over to the next year under any circumstances—the use-it-or-lose-it rule is set by federal tax law, not your employer.
  • A grace period (offered by some employers) gives you until mid-March to spend the prior year's FSA money, but this is optional and not may provide.
  • Carryover of up to $610 (as of 2024, adjusted annually) is allowed only in limited cases where your employer has adopted a carryover provision, and only if your plan document explicitly permits it.
  • You must estimate your annual healthcare expenses carefully when you enroll, because overestimating means losing money to the forfeiture rule.
  • If you leave your job or experience a may have access to life event, you may be able to withdraw remaining FSA funds, but this depends on your plan's rules and the reason for the change.

The use-it-or-lose-it rule and how it works

The IRS prohibits FSA balances from rolling over into the next plan year. This rule exists because FSAs are funded with pre-tax dollars—money that would otherwise be subject to income and payroll taxes. To prevent people from accumulating large tax-free reserves, the IRS requires that FSA plans include a forfeiture clause. Any money left unspent at the end of the plan year is forfeited and returned to the employer's general fund or used to offset plan administration costs.

The forfeiture happens automatically. You do not need to do anything, and your employer does not need to notify you in advance (though many do). On the last day of your plan year, your FSA account closes, and any remaining balance is gone. You cannot transfer it to a spouse's FSA, roll it into an IRA, or carry it forward in any form.

This rule applies to all FSAs, regardless of employer size or industry. It is a federal requirement, not a choice your employer makes.

Grace periods: the limited extension option

Some employers offer a grace period as part of their FSA plan design. A grace period extends the spending deadline by up to 2.5 months into the following calendar year. If your employer offers a grace period, you typically have until March 15 to spend money from the prior year's FSA balance.

Grace periods are entirely optional. Your employer can choose to include one or not, and they can change their decision year to year. Check your plan documents or ask your benefits administrator whether your FSA includes a grace period. If it does, the deadline will be listed in your plan summary or benefits guide.

Even with a grace period, any money still in your account after the grace period ends is forfeited. The grace period simply gives you more time to spend what you already contributed—it does not allow you to carry money forward into the next plan year.

Carryover provisions: a rare alternative

In 2013, the IRS introduced an alternative to the use-it-or-lose-it rule called a carryover provision. If your employer has adopted this option in their plan document, you may be able to carry over up to a certain dollar amount into the next plan year. As of 2024, that limit is $610, adjusted annually for inflation.

Carryover is not automatic and is not the default. Your employer must explicitly adopt it in the plan document, and you must be enrolled in a plan that includes this provision. Even then, you can only carry over up to the annual limit—any amount above that is still forfeited. Many employers do not offer carryover because it complicates plan administration.

To find out whether your FSA plan includes a carryover provision, check your plan summary or contact your benefits administrator directly. Do not assume your plan has carryover just because you work for a large employer; it depends entirely on what your employer chose to include.

What happens to your FSA money when you leave your job

If you leave your job mid-year, your FSA account typically closes on your last day of employment or your last day of coverage, whichever comes first. Any remaining balance is forfeited, even if you had planned to use it. The use-it-or-lose-it rule applies regardless of whether you left voluntarily or were terminated.

Some plans allow you to continue FSA coverage under COBRA (Consolidated Omnibus Budget Reconciliation Act), which means you can keep your account open and continue spending from it for a limited time. However, COBRA coverage is expensive because you pay the full premium plus an administrative fee, and you must elect it within 60 days of losing coverage. COBRA does not extend your FSA balance—it only extends the time you have to spend what remains.

If you change jobs and your new employer offers an FSA, you cannot transfer your old FSA balance to the new one. You start fresh with a new account at your new employer.

Strategies to avoid losing FSA money

The key to using your FSA effectively is estimating your annual healthcare expenses as accurately as possible during open enrollment. Review the past year's medical, dental, and vision bills to get a realistic picture of what you actually spend. Common may be able to access expenses include copays, deductibles, prescription medications, dental work, vision care, and certain over-the-counter items (with a prescription).

If you are unsure whether an expense qualifies, check the IRS Publication 502 or ask your FSA administrator before you enroll. Overestimating your expenses means money sits unused and gets forfeited. Underestimating means you pay for some healthcare costs with after-tax dollars, which is less efficient but safer than losing money.

If your employer offers a grace period, factor that into your calculation. You have extra time to spend money from the prior year, so you can be slightly more aggressive with your estimate. If your plan includes carryover, you have even more flexibility—you can carry over up to the annual limit, which reduces the pressure to spend everything by year-end.

Some employers also allow mid-year changes to your FSA contribution if you experience a may have access to life event (marriage, birth of a child, loss of coverage, significant change in healthcare costs). If your circumstances change during the year, ask your benefits administrator whether you can adjust your contribution.

FSA versus HSA: rollover differences

If you have access to a health savings account (HSA), the rollover rules are completely different. HSA balances roll over automatically from year to year with no limit. Money you contribute to an HSA in 2024 can sit in the account indefinitely and be spent years later. This makes HSAs much more flexible for long-term healthcare savings.

FSAs and HSAs serve different purposes. FSAs are designed for predictable, near-term healthcare expenses. HSAs are designed for long-term healthcare savings and can function as retirement accounts. If your employer offers both, an HSA is generally the better choice for building savings, but an FSA can be useful if you have consistent annual healthcare expenses you want to pay with pre-tax dollars.

Frequently Asked Questions

Can I roll my FSA balance into an IRA or 401(k)?

No. FSA balances cannot be transferred to any other account type, including IRAs, 401(k)s, or HSAs. The money is forfeited at the end of the plan year, period. There is no workaround or alternative method to preserve it.

What if I have money left in my FSA and I'm about to lose coverage?

Spend it before your coverage ends. Once your FSA coverage terminates, your account closes and any remaining balance is forfeited. If your employer offers COBRA, you can elect it to extend coverage and continue spending, but you must act within 60 days of losing coverage and you must pay the full premium yourself.

Does a grace period mean I can carry money over?

No. A grace period gives you extra time to spend money from the current plan year, but it does not carry the balance forward. After the grace period ends (typically March 15), any unspent money is forfeited. Only a carryover provision, if your plan includes one, allows you to move money into the next year.

Can I get my FSA money back if I don't use it?

No. Once the plan year ends and your balance is forfeited, there is no process to recover it. The money goes back to your employer. The only way to avoid this is to estimate your expenses carefully during enrollment and spend what you contribute before the deadline.

If my employer offers carryover, how much can I carry over?

The IRS limit for carryover is $610 as of 2024, adjusted annually for inflation. If your plan includes a carryover provision, you can carry over up to that amount. Any balance above the limit is still forfeited. Your employer sets the exact carryover amount in their plan document, so confirm the details with your benefits administrator.
