The 2026 FSA limits, and the biggest Dependent Care FSA jump since 1986

The 2026 health FSA contribution limit is $3,400, a routine inflation step up from $3,300 in 2025. The bigger story sits next to it: the Dependent Care FSA limit jumped to $7,500 for single filers and married couples filing jointly, up from $5,000 — the first change to that number since 1986. Both accounts shelter money from taxes before it hits a paycheck, but they work by different rules, and the gap between them matters more than usual this year.

The 2026 limits, side by side

The health FSA figures come from the IRS's 2026 inflation-adjustment announcement, the same release that set the 2026 tax brackets. The Dependent Care FSA figures are confirmed in the IRS's own Employer's Tax Guide to Fringe Benefits (Publication 15-B) for 2026, which sets out the new $7,500 exclusion for employer-provided dependent care assistance.

Why the health FSA number moves a little every year

The health FSA limit is adjusted for inflation annually, the same mechanism behind the standard deduction and tax bracket updates — a formula applied to prior-year figures, not a policy decision made fresh each year. That is why it tends to move by a comparatively small, predictable amount: $100 for 2026, following a $100 increase for 2025. The carryover limit moves with it, since it is set at 20% of the contribution limit — $680 is exactly 20% of $3,400. A plan can offer the carryover, a grace period of up to two and a half months to spend leftover funds, or neither, but not both together; check your own employer's plan document, since the choice is theirs, not a federal default.

Why the Dependent Care FSA number did something unusual

The $5,000 Dependent Care FSA limit was not adjusted for inflation the way the health FSA is — it was a fixed dollar figure written into the tax code in 1986 and left untouched for essentially four decades, aside from a temporary, one-year pandemic-era increase to $10,500 that expired after 2021. The increase to $7,500 for 2026 is a permanent statutory change, not an inflation formula catching up — Congress set the new figure directly. That distinction matters going forward: unlike the health FSA limit, there is no guarantee the $7,500 figure moves again next year unless a future law changes it, since nothing in the current provision ties it to inflation the way the health FSA limit is tied.

The rule that trips people up: no Dependent Care FSA carryover

A health FSA and a Dependent Care FSA are easy to confuse because they are enrolled in together during the same open enrollment and paid out of the same kind of payroll deduction, but they behave differently at year end. A health FSA can offer a $680 carryover into the next year. A Dependent Care FSA cannot — by law, unused funds are forfeited at year end unless the employer's plan offers a grace period (typically up to two and a half extra months) to spend down what is left, and even then nothing carries forward to add to next year's contributions. With the cap $2,500 higher for 2026, overestimating childcare costs and losing the excess is a more expensive mistake than it used to be.

What the increase is worth on a real childcare bill

Take a married couple filing jointly with two children in full-time daycare, comfortably spending more than $7,500 a year on care. Maxing the new 2026 limit instead of the old $5,000 cap shelters an extra $2,500 of income from both federal income tax and payroll (FICA) tax:

That total ignores state income tax, which would add more in most states that tax wages. It also assumes the couple actually spends the full $7,500 on qualifying dependent care — money contributed but not spent, remember, is forfeited rather than carried over, so this only pays off if the childcare bill is real and documented.

One more rule: the Dependent Care Tax Credit still exists, but not on the same dollars

A separate federal tax break, the Child and Dependent Care Credit, also covers daycare costs — but the same dollar of spending cannot be run through a Dependent Care FSA and claimed for the credit too. Money reimbursed through the FSA is simply subtracted before the remaining eligible expenses (if any, up to the credit's own separate cap) are considered for the credit. For most households with access to an employer Dependent Care FSA and a marginal tax rate above roughly 12%, the FSA route saves more, because it avoids both income tax and FICA rather than just producing a partial credit — but a household with lower income, or no employer plan on offer, may come out ahead relying on the credit instead. Comparing the two directly, for your specific income and spending, is worth doing before committing to a full year of FSA payroll deductions you cannot easily undo mid-year.

A health FSA usually rules out a Health Savings Account

One more limit worth checking before enrolling: a standard, general-purpose health FSA is not compatible with a Health Savings Account (HSA) in the same year for the same person, because HSA eligibility requires being covered only by a qualifying high-deductible health plan with no other disqualifying coverage, and a general-purpose FSA counts as disqualifying coverage. Employers who want to offer both typically use a "limited-purpose" FSA instead, restricted to dental and vision expenses only, which does not conflict with HSA eligibility. The $3,400 2026 limit applies to a limited-purpose FSA the same way it applies to a general-purpose one, but the two accounts are used very differently — anyone choosing between them, or weighing an HSA-eligible health plan against a traditional one with a general-purpose FSA, should confirm with their employer's plan documents which version is actually on offer, since the wrong assumption can mean an accidental HSA contribution error to unwind later. The IRS lays out the compatibility rules in Publication 969.
