HSA vs FSA ended by saying the Dependent Care FSA was not covered there. Since then the 2026 limit has risen from $5,000 to $7,500 — $2,500 more, half as much again.
1. Same name, different container. A Health FSA is $3,400 and a Dependent Care FSA is $7,500 — 2.2 times. They do not share a limit either.
2. Filing separately is exactly half. $3,750 — and it was half in 2025 too, at $2,500.
3. Earnings cap the limit. The source is explicit: “the smaller of the earned income of either the employee or employee’s spouse” — whoever earns less sets the ceiling.
The 2026 limit went up
Publication 503 for 2025 read “For 2025, the maximum amount that can be excluded… is $5,000 ($2,500 if married filing separately)”. Publication 15-B for 2026 says “up to $7,500 ($3,750 if married filing separately)”.
Filing separately stays exactly half in both years (our calculation). What changed is the $2,500 on top.
Both say “FSA”, and the sizes differ
Benefits paperwork calls both of them an FSA, which is where they get mixed up. They pay for different things and the limits differ.
| Health FSA | Dependent Care FSA | |
|---|---|---|
| 2026 limit | $3,400 | $7,500 |
| Pays for | Medical care | Care for a dependent |
| Carryover | Up to $680 | Not in Publication 503 |
| Earnings limit | None | Yes — up to the lower earner |
One person can hold both. They do not share a limit — $3,400 for medical care and $7,500 for dependent care are separate containers.
Earnings cap the limit
This condition attaches only to the Dependent Care FSA. In the source’s own words — “the exclusion can’t be more than the smaller of the earned income of either the employee or employee’s spouse”.
So the lower-earning spouse’s earned income is the ceiling. If one of you has taken time off and has no earned income, the $7,500 limit does not help you take that much out.
There is one exception (an earlier version said we could not verify one). Publication 15-B says “Special rules apply to determine the earned income of a spouse who is either a student or not able to care for themselves” and points to Publication 503, which treats that spouse’s earned income as “each month … at least $250 if there is one qualifying person … or at least $500 if there are two or more”. A full year of that is $3,000 or $6,000 — still short of $7,500 (our arithmetic). A spouse off work for other reasons gets no such rule.
And anything received above the limit is included in wages. The excess is simply taxed; there is no separate penalty on top.
The higher limit left no room for the credit
It does not end at “$2,500 more, so $2,500 better off”. Every dollar excluded is a dollar the dependent care credit can no longer count. Form 2441 says it directly: “the amount of the excluded benefits… reduces the dollar limit”.
The expense cap for two or more qualifying people is $6,000. In 2025 an exclusion of $5,000 still left $1,000 for the credit to work with. In 2026 the $7,500 exclusion goes past the cap, so nothing is left (our calculation). With one child, at $3,000, there was nothing left in either year.
Which of the two suits you depends on your income and your rate — this piece does not make that call. It records only that “the limit went up, so put the maximum in” does not follow automatically.
The law behind the increase
This is the gap where we wrote that we could not identify the legislation. It is P.L. 119-21, section 70404 — the IRS writes: “P.L. 119-21, section 70404, increased the maximum amount of the exclusion to $7,500 beginning in 2026.”
And note where that sentence appears: in a correction notice. The IRS itself printed $5,000 in the 2026 W-2 instructions and had to put it right. So if your employer’s handbook still says $5,000, that is not surprising — the 2026 figure is $7,500.
Questions this leaves
If both spouses enrol, is it $7,500 each?
The source states only “$7,500, or $3,750 if married filing separately”. That separate-return figure being exactly half reads as a household limit, but we could not find the source addressing “what if both enrol” directly. Check your plan document and a tax professional.
Is there a carryover or a grace period?
A grace period exists if your plan allows it. The sentence missing from Publications 503 and 15-B is in the Form 2441 instructions: “your employer may have permitted you to carry forward any unused amount from 2024 to use during a grace period in 2025, as described in Notice 2005–42” (checked 27 September 2026). So the basis is Notice 2005-42, and whether it applies is your employer plan’s choice. The $680-style carryover still appears only under the Health FSA heading (Publication 15-B). Check the length and availability in your plan document.
Can I take the tax credit as well?
Every excluded dollar reduces the expenses the credit can use. Form 2441: “If you exclude dependent care benefits from your income, the amount of the excluded benefits… reduces the dollar limit.” The caps are $3,000 for one qualifying person and $6,000 for two or more — so a $7,500 exclusion in 2026 takes both to zero (see above).
Why did it rise to $7,500?
P.L. 119-21, section 70404 raised it (see above). What this piece still does not cover is the legislative history — how that section came to be included.
Sources and where to check
IRS Publication 15-B (2026) — Employer’s Tax Guide to Fringe Benefits. “An employee can generally exclude from gross income up to $7,500 ($3,750 if married filing separately) of benefits received under a DCAP each year.” · “the exclusion can’t be more than the smaller of the earned income of either the employee or employee’s spouse” · for the Health FSA, “a cafeteria plan may not allow an employee to request salary reduction contributions for a health FSA in excess of $3,400”. (irs.gov)
IRS Publication 503 (2025) — Child and Dependent Care Expenses. “For 2025, the maximum amount that can be excluded from an employee’s income through a dependent care assistance program is $5,000 ($2,500 if married filing separately).” Source for the 2025 figures compared here. (irs.gov)
Our own calculation — the $2,500 increase, “exactly half for a separate return”, and the 2.2 times against a Health FSA are worked out from the figures above. The $3,400 Health FSA limit and the $680 carryover match what we confirmed in HSA vs FSA.
IRS correction notice — dependent care benefits exclusion in the 2026 Forms W-2 and W-3 instructions — “P.L. 119-21, section 70404, increased the maximum amount of the exclusion to $7,500 beginning in 2026.” It corrects the $5,000 printed in those instructions. (irs.gov)
IRS Form 2441 instructions — “If you exclude dependent care benefits from your income, the amount of the excluded benefits… reduces the dollar limit”, with caps of $3,000 for one qualifying person and $6,000 for two or more. The $1,000 and $0 left over are our own subtraction. (irs.gov)
What we could not verify — how it works when both spouses enrol, and whether a Dependent Care FSA has a carryover or grace period. On the second we did confirm that Publication 503 carries no such sentence. Neither has been filled in by guesswork.
As of August 2026, federal only. Not tax advice. The medical-side accounts are in HSA vs FSA. What happens when an HSA is spent on something that does not qualify is in non-qualified HSA withdrawals.
