Dependent Care FSA Is $7,500 in 2026: Why It Beats the Child Care Credit for High Earners
The dependent care FSA limit rose to $7,500 in 2026. For $250K+ households it can save about $2,600 to $3,300 a year, versus a $600 to $1,200 child care credit.

The dependent care FSA limit is $7,500 per household in 2026 ($3,750 if married filing separately), up from $5,000, and it stays $7,500 for plan year 2027 because the amount is not indexed. For a household earning $250,000 or more, running $7,500 of child care through the FSA saves roughly $2,600 to $3,300 a year in our worked examples, while the child and dependent care credit is worth only $600 to $1,200 at the 20% rate most high earners get.
The One Big Beautiful Bill Act (Public Law 119-21) raised the cap and also rebuilt the child care credit. The new credit helps middle-income families, but for $200K+ households the FSA still wins, and a full $7,500 election now eliminates the credit entirely. If your 2027 open enrollment is happening now, this is the decision to get right.
Key Facts: Dependent care FSA and child care credit for 2026
- Dependent care FSA exclusion: $7,500 per household ($3,750 married filing separately), effective for taxable years beginning after December 31, 2025
- The $7,500 is not indexed for inflation, so it is also the 2027 limit unless Congress acts
- Child and dependent care credit: 20% of up to $3,000 (one child) or $6,000 (two or more) once AGI exceeds $206,000 (joint) or $103,000 (other filers)
- Every FSA dollar reduces the credit’s expense limit dollar for dollar, so a full $7,500 election leaves $0 of credit
- FSA dollars skip federal income tax, Medicare tax, Social Security tax (below the $184,500 2026 wage base), and state tax in states that follow the federal exclusion
- Unused balances are forfeited; a plan may offer a grace period of up to 2 months and 15 days, but no carryover
What Changed: $5,000 to $7,500
A dependent care FSA is a dependent care assistance program (DCAP) under IRC section 129: you elect an amount at open enrollment, it comes out of pay before tax, and you are reimbursed for qualifying care.
Section 70404 of Public Law 119-21 changed the statutory cap in section 129(a)(2)(A) from $5,000 to $7,500, and from $2,500 to $3,750 for a married person filing separately, for taxable years beginning after December 31, 2025. The IRS confirms the new figures in Publication 15-B (2026).
Three details matter more than the headline number:
- It is not indexed. Section 129 has no cost-of-living adjustment. The health FSA limit rose to $3,400 for 2026 under Rev. Proc. 2025-32 because section 125(i) is indexed; the dependent care cap will sit at $7,500 until Congress changes it.
- It is a household cap for married couples. On a joint return, Form 2441 Part III totals the benefits in box 10 of your Forms W-2 against one limit, and the separate-return limit is exactly half.
- Your employer has to offer it. The statute caps what you can exclude; your employer’s written plan (section 129(d)(1)) caps what you can elect. Form 2441 says not to exclude more than “the maximum amount allowed under your dependent care plan.” The draft 2026 Form 2441 instructions add that your employer can tell you whether your plan was amended to raise the limit. Check your 2027 enrollment materials.
How the Credit Changed (and Why It Still Loses at High Incomes)
Section 70405 rewrote the credit’s applicable percentage in IRC section 21(a)(2), also for taxable years beginning after December 31, 2025. The statute now reads: 50%, reduced (not below 35%) by 1 point for each $2,000 or fraction of AGI above $15,000, then further reduced (not below 20%) by 1 point for each $2,000 ($4,000 on a joint return) or fraction above $75,000 ($150,000 joint).
The expense limits did not change: $3,000 for one qualifying person, $6,000 for two or more, and neither those limits nor the AGI thresholds are indexed. For comparison, the 2025 Form 2441 rate table drops to 20% at any AGI over $43,000.
| AGI (joint return) | AGI (single or head of household) | Credit rate | Max credit, 1 child | Max credit, 2+ children |
|---|---|---|---|---|
| $15,000 or less | $15,000 or less | 50% | $1,500 | $3,000 |
| $43,001 to $150,000 | $43,001 to $75,000 | 35% | $1,050 | $2,100 |
| $170,000 | $85,000 | 30% | $900 | $1,800 |
| $190,000 | $95,000 | 25% | $750 | $1,500 |
| $201,000 | $100,500 | 22% | $660 | $1,320 |
| Over $206,000 | Over $103,000 | 20% | $600 | $1,200 |
Rates computed from IRC section 21(a)(2) as amended. Between $15,000 and $43,000 the rate steps from 49% down to 36%. “Fraction thereof” means any amount over a step boundary costs the full point: joint AGI of $206,000 gets 21%, and $206,001 gets 20%.
The credit is nonrefundable and married couples generally must file jointly. For most readers, the bottom row applies: 20% of at most $6,000, or $1,200.
The Coordination Rule That Kills the Credit
Section 21(c) says the $3,000 or $6,000 expense limit “shall be reduced by the aggregate amount excludable from gross income under section 129.” IRS Publication 503 puts it plainly: if you exclude dependent care benefits, “you must subtract that amount from the dollar limit that applies to you.” On Form 2441, line 27 is $3,000 or $6,000, line 28 is your excluded benefits, and line 29 tells you to stop if the difference is zero or less.
| Children in care | Credit expense limit | FSA election | Remaining credit base | Credit at 20% |
|---|---|---|---|---|
| 1 | $3,000 | $0 | $3,000 | $600 |
| 1 | $3,000 | $7,500 | $0 | $0 |
| 2 or more | $6,000 | $0 | $6,000 | $1,200 |
| 2 or more | $6,000 | $5,000 | $1,000 | $200 |
| 2 or more | $6,000 | $7,500 | $0 | $0 |
Under the old $5,000 cap, a two-child family kept a $1,000 credit base, worth $200 at 20%. At $7,500 that disappears, but the extra $2,500 of FSA room is worth far more than $200 at high-earner tax rates.
What the FSA Actually Saves You
FSA dollars are excluded from more than income tax. Publication 15-B lists dependent care assistance (up to the limit) as exempt from federal income tax withholding, Social Security and Medicare tax, and FUTA. That stacks up to:
- Federal income tax at your marginal bracket (2026 brackets from Rev. Proc. 2025-32)
- Social Security tax of 6.2%, but only on wages below the 2026 wage base of $184,500 (Publication 15)
- Medicare tax of 1.45%, plus the 0.9% Additional Medicare Tax if Medicare wages exceed $250,000 on a joint return, $125,000 married filing separately, or $200,000 for all other filers (Topic 560)
- State income tax, in states that follow the federal exclusion
| Situation | Federal rate | Social Security | Medicare | State (assumed) | Savings per $1,000 of FSA | Credit per $1,000 (20%) |
|---|---|---|---|---|---|---|
| 22% bracket, under wage base, no Add’l Medicare | 22% | 6.2% | 1.45% | 5% | $346.50 | $200 |
| 24% bracket, under wage base, Add’l Medicare | 24% | 6.2% | 2.35% | 5% | $375.50 | $200 |
| 35% bracket, over wage base, Add’l Medicare | 35% | 0% | 2.35% | 5% | $423.50 | $200 |
| 37% bracket, over wage base, Add’l Medicare | 37% | 0% | 2.35% | 5% | $443.50 | $200 |
The 5% state rate is an illustrative assumption; in a no-income-tax state, subtract $50 per $1,000. If your state does not follow the federal exclusion, or conforms to the Internal Revenue Code as of a fixed date and has not adopted the $7,500 increase, ask your payroll team or CPA.
Worked Examples
Assumptions for all examples: 2026 tax law; the standard deduction ($32,200 joint, $24,150 head of household); each worker defers $24,500 to a traditional 401(k) (the 2026 limit in Notice 2025-67); no other income or adjustments; a flat 5% state tax that follows the federal exclusion; enough tax liability to use the full credit; and at least $7,500 of qualifying care. No one crosses a bracket line, so each saving is a flat percentage of $7,500.
Example 1: $400,000 MFJ, two kids in daycare
- Spouse A earns $250,000; Spouse B earns $150,000. Two children, ages 2 and 4, in full-time daycare at $30,000 a year.
- AGI: $400,000 minus $49,000 of 401(k) deferrals = $351,000. Taxable income: $351,000 minus $32,200 = $318,800, in the 24% bracket ($211,400 to $403,550). With the FSA, taxable income is $311,300, still 24%.
- Credit rate at $351,000 joint AGI: 20%.
Credit only: 20% x $6,000 = $1,200.
FSA of $7,500 through Spouse B’s employer:
| Tax avoided | Math | Savings |
|---|---|---|
| Federal income tax | 24% x $7,500 | $1,800.00 |
| Social Security (B is under $184,500) | 6.2% x $7,500 | $465.00 |
| Medicare | 1.45% x $7,500 | $108.75 |
| Additional Medicare (household Medicare wages over $250,000) | 0.9% x $7,500 | $67.50 |
| State (5% assumption) | 5% x $7,500 | $375.00 |
| Total FSA savings | 37.55% x $7,500 | $2,816.25 |
| Remaining credit | ($6,000 minus $7,500) is below $0 | $0.00 |
FSA beats the credit by $2,816.25 minus $1,200 = $1,616.25.
Which spouse elects matters. Spouse A’s $250,000 is above the Social Security wage base before and after a $7,500 reduction, so running the FSA through Spouse A’s payroll saves no Social Security tax: $2,816.25 minus $465.00 = $2,351.25. If both employers offer a DCAP, elect through the spouse who stays under $184,500.
Example 2: $250,000 MFJ, one child in preschool
- Both spouses earn $125,000. One child, age 3, in preschool at $15,000 a year (preschool below kindergarten counts as care).
- AGI: $250,000 minus $49,000 = $201,000. Taxable income: $201,000 minus $32,200 = $168,800, in the 22% bracket ($100,800 to $211,400). With the FSA, $161,300, still 22%.
- Credit rate at $201,000 joint AGI: AGI exceeds $150,000 by $51,000; $51,000 / $4,000 = 12.75, which rounds up to 13 points under “or fraction thereof”; 35% minus 13 = 22%.
This household sits inside the new phase-down band, where the OBBBA credit got richer. It still loses.
Credit only: 22% x $3,000 = $660.
FSA of $7,500: federal 22% ($1,650.00) + Social Security 6.2% ($465.00, both spouses under $184,500) + Medicare 1.45% ($108.75) + state 5% ($375.00) = 34.65% x $7,500 = $2,598.75. No Additional Medicare Tax applies because combined Medicare wages are not over $250,000. Remaining credit: $3,000 minus $7,500 is below zero, so $0.
FSA beats the credit by $2,598.75 minus $660 = $1,938.75. Even if this family had two children and a $1,320 credit (22% x $6,000), the FSA would win by $1,278.75.
Example 3: $500,000 single parent, above the wage base
- Head of household earning $500,000 in salary. One child, age 6, in kindergarten. Kindergarten tuition does not count, but after-school care, a summer day camp, and a part-time nanny’s wages plus the employer payroll taxes on them total well over $7,500.
- AGI: $500,000 minus $24,500 = $475,500. Taxable income: $475,500 minus $24,150 = $451,350, in the 35% head-of-household bracket ($256,200 to $640,600). With the FSA, $443,850, still 35%.
- Credit rate: AGI is over $103,000, so 20%.
Credit only: 20% x $3,000 = $600.
FSA of $7,500: federal 35% ($2,625.00) + Medicare 1.45% ($108.75) + Additional Medicare 0.9% ($67.50, wages over $200,000) + state 5% ($375.00) = 42.35% x $7,500 = $3,176.25. Social Security saves nothing because wages stay above $184,500 even after the reduction.
FSA beats the credit by $3,176.25 minus $600 = $2,576.25.
For a fourth data point, a $1,000,000 joint household with both spouses above the wage base and two children (taxable income $1,000,000 minus $49,000 minus $32,200 = $918,800, in the 37% bracket) saves 37% + 2.35% + 5% = 44.35% x $7,500 = $3,326.25, against a $1,200 credit.
Annual tax savings: $7,500 dependent care FSA vs. the credit alone

The Rules That Decide Whether You Can Use It
Who counts as a qualifying person
Under IRC section 21(b)(1), which section 129 borrows, care must be for:
- Your dependent child who is under 13 when the care is provided
- A dependent who is physically or mentally unable to care for themselves and lives with you more than half the year
- Your spouse who is physically or mentally unable to care for themselves and lives with you more than half the year
Expenses after a child’s 13th birthday stop qualifying, so a child turning 13 mid-year means a smaller election.
What expenses qualify
| Expense | Qualifies? | Source note |
|---|---|---|
| Daycare center or family daycare | Yes | Care so you can work |
| Preschool, nursery school, pre-K | Yes | Programs below kindergarten are care (Pub 503) |
| Kindergarten or higher-grade tuition | No | Pub 503: not expenses for care |
| Before or after school care (K and up) | Yes | Pub 503 |
| Day camp | Yes | Pub 503 |
| Overnight camp | No | Excluded by IRC section 21(b)(2) |
| Nanny or au pair wages | Yes | Care in your home |
| Employer payroll taxes you pay on a nanny | Yes | Pub 503: taxes on wages for care are work-related |
| Payments to your own child under 19, your spouse, or anyone you can claim as a dependent | No | IRC section 129(c), Pub 503 |
Prepaid care counts in the year the care is provided, not the year you pay. The exclusion follows the same rule: section 129(a)(2) applies the cap to care “provided during a taxable year,” and any excess is taxable in the year the care was provided.
The earned income limit
The exclusion cannot exceed your earned income or, if married, your spouse’s earned income, whichever is less (section 129(b)). If one spouse does not work, the exclusion is generally $0. The exception: a spouse who is a full-time student or incapable of self-care is treated as earning $250 a month with one qualifying person or $500 a month with two or more (section 21(d)(2)). The deemed amount applies only for months the spouse is a full-time student or incapable of self-care, so a spouse with no other earnings who is a full-time student in all 12 months, with two kids in care, is deemed to earn $500 x 12 = $6,000, which caps the household exclusion at $6,000.
Use it or lose it, with an optional grace period
Money left in the account after the plan year is forfeited. A plan may add a grace period of up to 2 months and 15 days after the plan year ends, during which new expenses can be paid from last year’s balance (Notice 2013-71, citing Notice 2005-42). The carryover option, now up to $680 for 2026, applies only to health FSAs. Grace period spending shows up on Form 2441 for the following year, and it counts against that year’s $7,500 because the cap follows the year the care is provided.
Changing your election mid-year
Elections are generally locked for the plan year. Treas. Reg. section 1.125-4 lets a plan permit changes for events such as marriage, divorce, birth, adoption, or a change in employment, and for dependent care, a cost change imposed by a provider who is not a relative. Your plan document decides which of these it allows.
The Employer Side: HCE Caps and the August 2026 Proposed Rules
This is the part that catches high earners. Section 129(d) requires a DCAP not to discriminate in favor of highly compensated employees. The best-known test, section 129(d)(8), requires that the average benefits provided to non-HCEs be at least 55% of the average benefits provided to HCEs; plans funded by salary reduction may disregard employees earning under $25,000. For 2026 testing, Publication 15-B defines an HCE as a 5% owner or an employee who received more than $160,000 in pay for the preceding year (the employer may limit the pay test to the top 20% by pay). Notice 2025-67 keeps the section 414(q) threshold at $160,000 for 2026.
If the plan fails, non-HCEs keep their exclusion and HCEs lose theirs (section 129(d)(1)). One way an employer can head that off is to limit HCE elections below the plan maximum; that is a plan design choice, not a statutory rule, so whether and when your employer does it depends on your plan. A higher cap can make the 55% test harder to pass if HCEs elect the new $7,500 maximum while other employees elect less, so check whether your plan caps HCEs for 2027.
The IRS has now proposed regulations for these tests. REG-101355-26, published in the Federal Register on August 11, 2026 and reprinted in Internal Revenue Bulletin 2026-37, would:
- Count an employee in the 55% test’s average only if that employee received more than $0 of benefits during the plan year, rather than averaging over every eligible employee
- Restate the statutory rule (section 129(d)(9)) that employees who have not reached age 21 and completed one year of service, plus certain collectively bargained employees, are excluded from the eligibility and 55% tests
- Let a failing plan be treated as passing for HCEs if, by the Form W-2 furnishing deadline, the employer includes the affected HCEs’ excess benefits in their gross income
The rules are proposed, not final. They would apply to plan years beginning on or after publication of final regulations, but employers may rely on them now. The notice scheduled a public hearing for October 15, 2026, to be cancelled if no one asked to speak by September 25, 2026. Practically, an employer that re-runs its test under the proposed method may land on a different HCE cap than before, and if the plan still fails, the proposal’s fix is to treat the excess as taxable income for the affected HCEs.
When the FSA Makes Sense (and When It Does Not)
Max it out if: both spouses work (or the non-working spouse is a full-time student or disabled), you will spend at least $7,500 on qualifying care in the plan year, and your employer offers the full $7,500.
Elect less if: your qualifying expenses will be lower (a child turning 13, or moving from preschool into kindergarten where tuition stops counting), the lower earner’s earned income is under $7,500, or your employer caps HCE elections.
Skip it if: your only caregiver is someone you claim as a dependent, your own child under 19, or your spouse; one spouse has no earned income and is not a student or disabled; or your costs are only overnight camp and kindergarten tuition.
Common Mistakes
- Both spouses electing $7,500. The cap is per household on a joint return, so the second $7,500 becomes taxable income on Form 2441 line 26.
- Electing through the wrong spouse. If one spouse is above the $184,500 Social Security wage base and the other is not, electing through the lower earner adds 6.2% x $7,500 = $465 of savings.
- Assuming the new credit beats the FSA. The OBBBA credit headline says 50%, but that rate applies only at AGI of $15,000 or less. Above $206,000 joint AGI it is 20%, the same rate high earners got in 2025.
- Counting kindergarten tuition or overnight camp. Neither qualifies. Before and after school care and day camp do.
- Over-electing. Unused money is forfeited. Elect only for care you are confident you will use.
- Skipping Form 2441. If you received dependent care benefits, Form 2441 requires Part III and Part I’s care provider name, address, and SSN or EIN. Get your provider’s taxpayer ID now, not in April.
- Forgetting household employment taxes. If your nanny is your household employee, you may owe employment taxes (Schedule H). Those taxes are themselves qualifying expenses.
What to Do This Open Enrollment
- Check your 2027 plan maximum. Confirm your employer’s dependent care election cap is $7,500 and whether HCE elections are capped lower.
- Pick the right spouse’s plan. If both employers offer a DCAP, elect through the spouse who stays under the $184,500 Social Security wage base. Do not elect at both.
- Size the election to 2027 care. Map out daycare, preschool, after-school, and summer day camp costs, and note any child who turns 13 or starts kindergarten.
- Spend down your 2026 balance. Submit claims for 2026 care before your plan’s run-out deadline, and find out whether you have a grace period into 2027.
- If you elected only $5,000 for 2026, you can still claim the credit on up to $1,000 more with two or more children ($6,000 minus $5,000), worth $200 at 20%.
- Line up the rest of open enrollment. The same window is when you set 401(k) deferrals and HSA elections; see the W-2 Tax Playbook for the full checklist, and pair the FSA with 529 plans if you are saving for school costs that the FSA cannot cover.
Frequently Asked Questions
What is the dependent care FSA limit for 2026?
$7,500 per household ($3,750 if married filing separately), up from $5,000 ($2,500). Public Law 119-21, section 70404, amended IRC section 129 for taxable years beginning after December 31, 2025. Your employer’s plan must also allow $7,500, since the plan sets what you can elect.
Is the $7,500 dependent care FSA limit per person or per household?
Per household for married couples. On a joint return, the $7,500 cap applies to both spouses’ dependent care benefits combined, which is why the separate-return limit is half ($3,750). If each spouse elects $7,500 at a different employer, the extra $7,500 becomes taxable income on your return.
Will the dependent care FSA limit go up in 2027?
No. Section 129 has no inflation adjustment, so the cap stays $7,500 for 2027 unless Congress changes the law. The health FSA limit ($3,400 for 2026) is indexed; the dependent care limit is not.
Can I use a dependent care FSA and the child and dependent care credit in the same year?
Yes, but every dollar of excluded FSA benefits reduces the credit’s $3,000 (one child) or $6,000 (two or more) expense limit dollar for dollar. A full $7,500 FSA election wipes out the credit base entirely, even with two or more children, because $6,000 minus $7,500 is below zero.
What is the child and dependent care credit percentage for high earners in 2026?
20% once AGI exceeds $206,000 on a joint return or $103,000 for other filers. The OBBBA rate starts at 50%, falls to 35%, holds there until AGI exceeds $150,000 joint ($75,000 other), then drops 1 point per $4,000 joint ($2,000 other) to 20%. At 20%, the maximum credit is $600 for one child or $1,200 for two or more.
How much does a $7,500 dependent care FSA save a high earner?
$2,598.75 to $3,326.25 a year in our worked examples, assuming 5% state tax. The FSA avoids federal income tax (22% to 37% in the examples), Medicare tax of 1.45% (2.35% with the Additional Medicare Tax), 6.2% Social Security tax below the $184,500 wage base, and state tax where your state follows the federal exclusion. The credit alone is worth $600 to $1,200 at 20%.
What child care expenses qualify for a dependent care FSA?
Care for a child under 13 (or a spouse or dependent who cannot care for themselves) so you can work: daycare, preschool and other programs below kindergarten, before and after school care, day camps, and nanny wages including the employment taxes you pay on them. Kindergarten tuition, overnight camp, and payments to your own child under 19 or to someone you can claim as a dependent do not qualify.
What happens to unused dependent care FSA money?
You forfeit it under the use-or-lose rule. Your plan may offer a grace period of up to 2 months and 15 days after the plan year ends to incur more expenses, but the up-to-$680 carryover allowed for health FSAs in 2026 does not apply to dependent care FSAs.
Can my employer limit my dependent care FSA election because I am a highly compensated employee?
Yes. The plan must pass nondiscrimination tests, including one requiring non-HCEs’ average benefits to equal at least 55% of HCEs’ average. For 2026 testing, an HCE is generally a 5% owner or someone paid more than $160,000 in the prior year. Proposed regulations from August 2026 (REG-101355-26) would count only employees who received benefits in the 55% test and let employers fix a failure by adding the excess to HCEs’ taxable income by the Form W-2 deadline.
Bottom Line
The dependent care FSA cap is $7,500 per household for 2026 and, because it is not indexed, for 2027 too. For households above about $206,000 of joint AGI, the rebuilt child care credit is still 20% of at most $6,000, so the credit tops out at $1,200 while the FSA saves $2,600 to $3,300 in our examples. Electing the full $7,500 erases the credit, and that is the right trade. Confirm your plan offers $7,500, elect through the spouse under the Social Security wage base, size the election to care you will actually use, and watch for an HCE cap.
