The 2025 FSA limits, and the dependent care number that did not move

The 2025 health FSA contribution limit is $3,300, up $100 from 2024. The Dependent Care FSA limit did not move at all — it held at $5,000 per household, exactly where it has sat since 1986. The two accounts look similar on a benefits enrollment form, but they are governed by completely different rules, and only one of them adjusts for inflation.

Every 2025 FSA figure in one table

The health FSA figures come from the IRS's Revenue Procedure 2024-40, released in October 2024. The Dependent Care FSA limit is not in that document at all — it is set separately, in the tax code itself.

Why the health FSA moved and the dependent care limit did not

The health FSA limit is inflation-indexed under Section 125(i) of the tax code, so the IRS recalculates it every year alongside dozens of other thresholds published in the same annual revenue procedure — tax brackets, the standard deduction, HSA limits, and more. That is why it rose to $3,300 for 2025.

The Dependent Care FSA limit is a different animal. It is set under Section 129(a)(2)(A), and Congress wrote that provision as a flat dollar figure rather than one tied to inflation. The number has been $5,000 since the Tax Reform Act of 1986 — not because nobody noticed inflation, but because nothing in the statute triggers a change. The IRS's own guidance confirms the $5,000 cap for 2025 is the same figure that applied decades earlier, only eroded by nearly four decades of inflation in real terms.

What the carryover actually buys you

A health FSA is use-it-or-lose-it by design, but a plan can optionally allow a carryover of unused funds into the next year — up to $660 for 2025 — instead of, not in addition to, a grace period. Not every employer plan offers a carryover at all; some instead give a grace period of up to two and a half extra months to spend the prior year's balance, and some offer neither. It is worth checking your own plan document before assuming either flexibility applies, since $660 is only a ceiling on what a plan is allowed to permit, not a guarantee that it does.

What the Dependent Care FSA actually covers

A Dependent Care FSA reimburses work-related care costs for a child under 13, or for a spouse or dependent who is physically or mentally incapable of self-care — daycare, before- and after-school programs, and summer day camp all typically qualify; overnight camp does not. The $5,000 limit is per household, not per spouse, so two working parents each with access to a Dependent Care FSA through their own employer still share a single $5,000 cap between them, and contributing to both accounts beyond that combined limit creates taxable income.

The Dependent Care FSA and the dependent care tax credit are not stackable

A separate benefit, the Child and Dependent Care Credit, applies to the same category of care expenses — but the two cannot both apply to the same dollar. Any amount reimbursed through a Dependent Care FSA reduces the pool of expenses left over to claim for the credit, dollar for dollar. For most moderate-to-higher earners the FSA is worth more, because it lowers both income and payroll tax at the source, while the credit is a smaller percentage of expenses that phases down as income rises. For a lower-income household the credit can sometimes come out ahead instead. Running both options against your own numbers before electing an amount is worth the extra ten minutes, since the FSA election is generally locked in for the full plan year.

The enrollment mechanics that catch people out

Both FSA types generally run on a calendar plan year and require an active election during open enrollment — nothing carries forward automatically, and an employee who does nothing is typically enrolled in neither account for the following year. Mid-year changes are usually restricted to a qualifying life event: a birth or adoption, marriage or divorce, a spouse's job change, or a change in daycare cost or provider. After the plan year ends, most plans allow a run-out period, commonly 90 days, to submit claims for expenses that were actually incurred during the year — a separate window from the grace period or carryover that extends when money can be spent, not just when it can be claimed.

What changes in 2026 — and what does not, yet

A provision of the law signed July 4, 2025 raises the Dependent Care FSA limit to $7,500 ($3,750 married filing separately) for tax years beginning after December 31, 2025 — the first change to that number since it was set. It is permanent, not a temporary boost, and it is not indexed to inflation either, so it will presumably sit at $7,500 for years before Congress revisits it again. None of this affects 2025 contributions, and the increase is optional for employers: a plan has to be amended to offer the higher limit, so it is worth confirming with your own benefits team once 2026 open enrollment arrives rather than assuming the new number applies automatically.

What maxing out both accounts is worth in 2025

Take a household in the 22% federal tax bracket that maxes out both a $3,300 health FSA and a $5,000 Dependent Care FSA in 2025 — $8,300 total, all pre-tax:

That is an illustration, not a guarantee — the real number depends on your actual marginal federal rate, whether your state taxes FSA contributions the same way (most follow the federal treatment, but not all), and whether you would have spent the full $8,300 on qualifying costs regardless. FSA money not spent by the plan's deadline is typically forfeited, so the tax benefit only holds if the spending was going to happen anyway.
