Unlike some healthcare FSAs, which the IRS allows to carry over a limited amount, dependent care FSAs (DCFSAs) don't get that same treatment. If your employer's plan includes a grace period, you may have a short window to spend down last year's balance. But the specific deadlines, and whether a grace period even exists, depend entirely on your plan.
This article breaks down the real distinctions that matter: rollover versus grace period versus run-out period, the deadlines for incurring expenses and filing claims, and whether you can adjust your contributions mid-year if your care situation changes.
Key Takeaways
- Dependent care FSA funds are forfeited at year-end unless your plan includes a grace period or another permitted extension.
- A grace period extends time to incur expenses; a run-out period only extends time to submit claims for expenses already incurred.
- Confirm your plan year, grace-period end date, and claims deadline directly with HR or your FSA administrator.
- Mid-year contribution changes require a qualifying event and plan approval, not just a change in your childcare needs.
Does a Dependent Care FSA Roll Over?
The IRS applies a "use it or lose it" rule to dependent care FSAs. Any funds left in the account after the plan year, or after an adopted grace period, must be forfeited. They can't be carried forward, and they can't be cashed out.
This surprises a lot of people because the rules changed for healthcare FSAs. Some health FSA plans now permit a limited carryover amount into the next year. Dependent care FSAs don't get that option.
IRS Notice 2021-15 confirms that a Section 125 cafeteria plan may not adopt a carryover feature for a dependent care assistance program.
What Can Actually Happen to Unused Funds
After the plan year closes, there are really only three outcomes:
- Forfeiture — the default outcome if the plan has no grace period or the money isn't used in time.
- Use during a grace period — if the employer's plan includes one.
- Claims run-out — extra time to submit receipts for expenses already incurred during the plan year, only if the plan document includes it.
Here's the part that matters most: your employer decides whether the plan offers a grace period. It's not a choice you make at enrollment, and it's not automatic. Some employers build one in; others don't.
Don't guess. Check your Summary Plan Description, open-enrollment materials, or benefits portal before assuming your plan works one way or another.
Example (hypothetical dates, not a universal rule): Say your plan year runs January 1 to December 31 with no grace period. Any unused balance is forfeited on January 1.
Compare that to a plan with a grace period through March 15. That same employee gets an extra 2.5 months to incur new eligible expenses with last year's leftover funds. Same benefit, very different outcome — entirely a matter of plan design.
How the Grace Period and Deadlines Work
A dependent care FSA grace period is an optional plan feature. It gives you extra time to incur new eligible care expenses with money left from the prior plan year.
If your employer offers one, it can't exceed 2.5 months. Per IRS Notice 2005-42, the deadline can't run later than the 15th day of the third calendar month after the plan year ends. That's a hard ceiling—some employers offer a shorter window or skip the grace period entirely.
Grace Period vs. Run-Out Period
These two terms get confused constantly, and the mix-up costs people money.
| Feature | Grace Period | Run-Out Period |
|---|---|---|
| What it extends | Time to incur new care expenses | Time to submit claims for care already received |
| Optional or required | Optional plan feature | Set by the employer's plan |
| Maximum length | 2.5 months (if adopted) | No single federal limit; plan-specific |
| Common mistake | Treating leftover funds as spendable all next year | Thinking you can still incur new care in this window |
A grace period only extends when new expenses can happen. A run-out period is only about claim paperwork for care that already took place.
Building Your Deadline Checklist
Before your plan year ends, confirm these items with HR or your administrator:
- Final date to incur care — last day a service can be provided and still use last year's funds
- Final date to submit a claim — filing deadline, often later than the incur date
- Post-termination deadline — separate cutoff if you leave the company mid-year
- Required documentation — provider name, address, and taxpayer ID (IRS Publication 503)
Paying a provider early does not make an expense eligible. The care itself must be provided during the eligible period. Prepaying December daycare for January does not hit this year's balance, and it does not pull next year's care forward either.
Example timeline: Plan year ends December 31. Grace period runs through March 15 (2.5 months). Run-out for filing claims might extend to April 30. Care must be provided by March 15; you may have until April 30 to file paperwork for expenses from the plan year or grace period. Always verify your plan's actual dates.
What Happens to Unused Dependent Care FSA Funds?
If there's no grace period, or if the grace period passes without the money being used, the remaining balance is forfeited. That's the ordinary outcome under the use-it-or-lose-it rule.
Forfeiture and an unsubmitted claim are not the same problem:
- Forfeited funds: Care was never provided, so there's nothing to claim.
- Unsubmitted claims: Care was provided on time, but the paperwork hasn't been filed yet. If you're still inside the run-out period, that money isn't lost—you just need to submit it.
Steps to Take Before the Deadline
- Review which care expenses actually qualify (after-school programs count; occasional weekend babysitting for date night generally doesn't).
- Contact your provider for the documentation you'll need: name, address, and tax ID.
- Submit claims early enough to fix rejected or incomplete paperwork before the run-out deadline closes.
- Follow up with your administrator on any pending claims to confirm they've been received and processed.
Juggling providers, receipts, and deadlines makes the claims process tedious for working parents. Helpr connects care payments to a DCFSA workflow so employees can pull booking receipts from the app and submit them straight to their FSA vendor.
If you've changed jobs or your plan terms changed mid-year, don't assume a standard federal number of days applies. IRS guidance doesn't set one universal run-out length—your written plan document controls that timeline.
Temporary pandemic-era relief provisions from 2020–2022 no longer apply to current plan years.
Can You Stop or Change Contributions Mid-Year?
Once you elect a contribution amount, it generally stays locked in for the plan year. Realizing your childcare costs went up (or down) isn't, by itself, a reason the IRS lets you change your election. That said, cafeteria plans may allow a change if a qualifying event occurs and your specific change is consistent with that event.
Qualifying Events That May Allow a Change
Under 26 CFR 1.125-4, permitted election changes generally require one of these triggers:
- Change in marital status — marriage, divorce, legal separation, annulment, or death of a spouse.
- Change in number of dependents — birth, adoption, placement for adoption, or death.
- Employment status change — for you, your spouse, or a dependent, including starting or ending a job, or certain leave changes.
- Dependent-care cost change — if imposed by a provider who isn't your relative.
- Dependent-care coverage change — such as switching providers or a change in care hours. Note that a qualifying child must be a dependent under age 13, and a qualifying person 13 or older must be unable to care for themselves and live with you more than half the year. Two things matter beyond the event itself: your specific plan document has to permit that type of change, and you have to request it within the plan's deadline. The regulation is permissive, not automatic. Stopping future contributions is different from recovering money already contributed. You can potentially halt payroll deductions going forward after a qualifying event, but funds already in the account remain subject to the same eligible-expense and deadline rules as before. Report a potential qualifying event to HR promptly, and bring supporting documentation (like a new job offer letter or a provider's rate change notice) when you request the change. For benefits teams, clear communication matters most. Employees whose care arrangements shift unexpectedly (a nanny who quits, a daycare that closes) need guidance on election-change windows and year-end deadlines before they're scrambling. Some employers pair DCFSA education with a backup-care benefit, such as Helpr's family-care platform, so employees have an immediate option when regular care falls through. That backup care is separate from the DCFSA itself. Helpr services aren't automatically reimbursable through a dependent care FSA, so employees still need to confirm eligibility with their plan administrator.
How to Avoid Losing Dependent Care FSA Funds
A little planning at enrollment prevents most year-end scrambling.
- Estimate conservatively. Base your contribution on care you're confident you'll use, not a best-case guess.
- Monitor your balance. Check mid-year, then again a few weeks before your plan-year or grace-period deadline—not the week claims close.
- Confirm eligibility before paying. After-school care that runs until your workday ends generally qualifies; weekend sitters for personal plans usually don't.
- Keep provider details on hand. Name, address, and taxpayer ID, per IRS Publication 503, so claims don't get rejected for missing information.
- File early. Submitting claims with time to spare lets you fix errors before the deadline actually closes.
Five Questions to Ask HR or Your Administrator
- Does our plan offer a grace period, and if so, what's the end date?
- What's the last date care can be provided and still count toward this year's funds?
- What's the separate deadline for submitting claims?
- What happens to my balance if I leave the company?
- Can I change my election after a qualifying event, and what's the request deadline?

Frequently Asked Questions
What happens to unused dependent care FSA funds?
Unused funds don't roll over and are forfeited unless your plan offers a grace period. Check your Summary Plan Description for the exact deadlines that apply to you.
Can I stop contributing to my dependent care FSA mid-year?
Mid-year changes are generally restricted, but they may be allowed after a qualifying life event, like a job change or marriage, if your plan permits it. Contact HR promptly to start the request.
Does a dependent care FSA have a grace period?
A grace period is optional and set by the employer, not guaranteed by law. If adopted, it can give you up to 2.5 additional months to incur eligible care expenses after the plan year ends.
What is the difference between a grace period and a run-out period?
A grace period gives extra time to incur new eligible expenses. A run-out period only gives extra time to submit claims for expenses you already incurred during the plan year or grace period.
What is the deadline to use dependent care FSA funds?
There's no single universal deadline. Check your plan year end date, any grace-period cutoff, and the separate claims-filing deadline, since all three vary by employer.
What happens to my dependent care FSA if I change jobs?
New contributions typically stop once you leave your employer's plan, but you may still be able to file claims for eligible expenses incurred before your termination date. Confirm the post-employment claims window with your former employer's administrator.
