Money left in a dependent care FSA at the end of the plan year is forfeited to your employer, and the use-it-or-lose-it rule that governs these accounts allows only one possible extension: a grace period of up to two and a half months, and only if your employer’s plan specifically adopts it.1FSAFEDS. FAQs – What Is the Use or Lose Rule With the 2026 household contribution limit rising to $7,500, a miscalculated election can mean walking away from real money.2FSAFEDS. Dependent Care FSA
Why the Money Is Forfeited
A cafeteria plan under Section 125 of the Internal Revenue Code cannot let participants defer compensation from one year to the next.3Office of the Law Revision Counsel. 26 US Code 125 – Cafeteria Plans Because your DCFSA contributions are excluded from taxable income, letting a balance carry indefinitely would function as tax-free deferred pay. The IRS blocks that by requiring anything left in the account after the plan year (and any grace period) to be permanently lost. The agency’s own description is blunt: an FSA cannot provide a cumulative benefit beyond the plan year.4Internal Revenue Service. FAQs for Government Entities Regarding Cafeteria Plans
The Grace Period Is the Only Extension
Some employers offer a grace period that gives you an extra two and a half months after the plan year ends to spend down your balance. For a calendar-year plan, that means eligible expenses incurred through March 15 can be reimbursed from the prior year’s leftover funds, with no dollar cap on how much of the balance you can apply.1FSAFEDS. FAQs – What Is the Use or Lose Rule
The grace period is optional. Your employer has to formally adopt it in the plan documents, so check with your benefits administrator before assuming you have one. If your plan does not include it, December 31 (or whatever date your plan year ends) is the hard deadline.
One thing dependent care FSAs cannot do, no matter what your plan says: carry over a set dollar amount into the next year. That option exists for health FSAs but is not available for DCFSAs.5FSAFEDS. Dependent Care FSA Carryover – FAQs The grace period is the only extension in the toolbox.
Two Deadlines, Not One
Losing money to forfeiture is often less about the calendar than about which calendar. Two separate deadlines control whether you get reimbursed, and confusing them is a common way to lose otherwise-eligible funds.
The first is the incurring deadline. This is the last day eligible care can actually be provided. For most plans that’s December 31, or March 15 if your plan offers a grace period. Care delivered after that date cannot be paid from the prior year’s balance.
The second is the run-out period. This is an administrative window after the incurring deadline for submitting paperwork on expenses that were already incurred on time. Ninety days is typical, but each employer sets its own length. Miss the run-out deadline and the money tied to that claim is forfeited even though the expense itself happened during an eligible period. Plan administrators have to enforce the cutoff uniformly and cannot grant individual extensions. If you have receipts sitting in a drawer from the fall, don’t push submission to the last week.
Why Balances Pile Up at Year-End
A dependent care FSA does not work like a health FSA, and the differences matter for whether you end the year with a leftover balance.
Your full annual election is not available on day one. A DCFSA can only reimburse up to what has actually been deposited so far through payroll deductions.2FSAFEDS. Dependent Care FSA If you elected $7,500 for the year and only $2,000 has been contributed by March, your reimbursement ceiling that month is $2,000. Contributions catch up to elections as the year progresses, which is why unspent money tends to concentrate late in the year rather than early.
Reimbursement is also based on when care was provided, not when you paid for it. If your day care requires a deposit in August for September enrollment, you cannot submit a claim until September’s care has actually been delivered.6Internal Revenue Service. Publication 503 – Child and Dependent Care Expenses Prepaying does not accelerate anything. This matters most in December: you cannot prepay January tuition and charge it against the current plan year.
Where Forfeited Money Actually Goes
Forfeited DCFSA funds do not go to the IRS. They become what benefits professionals call experience gains and they revert to your employer. The employer can retain the money in general assets, use it to offset plan administration costs, reduce future salary contributions on a uniform basis, or return the funds to employees uniformly. What the employer cannot do is refund your specific balance directly to you, because that would unwind the tax structure of the plan.1FSAFEDS. FAQs – What Is the Use or Lose Rule
In practice, most employers use forfeitures to help cover the administrative fees they pay the third-party administrator. From your side of the ledger, once the plan year and any grace period close, the money is gone.
How to Avoid Forfeiting a Balance
Estimate Carefully at Enrollment
Because the DCFSA has no carryover and only a conditional grace period, your election needs to reflect care you are confident you will use. For 2026 the household maximum is $7,500 (or $3,750 if married filing separately), the first permanent increase to the limit since 1986, and it is not indexed for inflation.2FSAFEDS. Dependent Care FSA The cap applies per household, so if both spouses have DCFSA access at their respective employers, combined contributions cannot exceed $7,500. Electing to the maximum without a matching care budget is the fastest route to a year-end forfeiture.
Watch for a Child Turning 13
Once a child turns 13, expenses for their care no longer qualify, even if the care arrangement continues.6Internal Revenue Service. Publication 503 – Child and Dependent Care Expenses If your child ages out mid-year, only the pre-birthday portion of the year’s care is reimbursable, which can leave a balance behind if you elected based on a full year of expenses.
Know What Happens If You Leave Your Job
If you separate from your employer mid-year, payroll contributions stop, but you can generally continue submitting claims for eligible care incurred through the end of the plan year as long as the account has a balance. You lose access to the grace period, though, because it requires active employment through December 31.7FSAFEDS. Separation and Retirement – FAQs Dependent care FSAs are generally not subject to COBRA continuation, so once the existing balance is used up or the plan year closes, the account is finished. A new employer’s DCFSA starts fresh; nothing transfers.
Run the Numbers Against the Tax Credit
The Child and Dependent Care Tax Credit normally applies to up to $3,000 in expenses for one qualifying person or $6,000 for two or more. Any dependent care benefits you exclude through your FSA must be subtracted from those limits dollar for dollar.8Internal Revenue Service. Topic No. 602, Child and Dependent Care Credit For most two-child families the DCFSA exclusion beats the credit, but if you contribute the full $7,500 and have $10,000 in annual care costs, the $2,500 above the FSA cap gets no additional credit either, because the $7,500 exclusion already exceeds the $6,000 credit limit. Comparing your bracket to both benefits before open enrollment is time well spent.
Submit Claims Promptly
Because reimbursement is capped at your current deposited balance, submitting claims monthly (rather than saving them for a year-end batch) keeps you aware of how much room is left and gives you time to adjust care spending if a balance is building. If your plan has a grace period, use January through mid-March deliberately for eligible expenses; if it does not, treat December as the real deadline and file the paperwork inside the run-out window.
