Dependent Care FSA vs Child Care Tax Credit Calculator

Quick answer: FSA, credit or both?

With one child, the dependent care FSA almost always wins: it shelters up to $7,500 from income tax, Social Security, Medicare and usually state tax, while the credit only covers $3,000 of costs. With two or more children it's closer, because the credit covers $6,000 at 35% for most families, $2,100. A full $7,500 FSA beats that when your federal bracket + 7.65% + state rate comes to more than 28%: in the 22% bracket and up, or in the 12% bracket with a state rate over about 8%. The credit can win in the 12% bracket without much state tax, when your plan only allows $5,000, or when you can't be sure you'll spend the money. At low incomes the FSA often wins again, because the credit is capped by your tax and crowds out the Child Tax Credit, while the FSA can raise the EITC. You can only use both when the FSA leaves some of the credit's $3,000/$6,000 limit unused.

"Keep" is the tax saved plus credits, including the change in the Child Tax Credit and EITC, compared with using neither. Your numbers depend on your pay split, state and plan, so run the calculator.

Why you usually can't use both: the $3,000/$6,000 rule

The credit works on up to $3,000 of costs for one child or $6,000 for two or more. That limit is reduced dollar for dollar by everything that goes through a dependent care FSA, your employer's money included, and costs the FSA paid can't be counted again (26 U.S.C. § 21(c)). It isn't "FSA first, then the credit on the rest of your costs":

• One child, $5,000 in the FSA: $3,000 − $5,000 is below zero, so no credit, however much more you spend.
• Two children, $5,000 in the FSA: $6,000 − $5,000 leaves $1,000 for the credit, worth $200–$500.
• Any number of children, $7,500 in the FSA: nothing left for the credit.

That's why the best answer is sometimes a smaller election, or none. With a $5,000 plan, two children and $150,000 of pay (no state tax), the credit alone leaves this family $2,100, and the full FSA $1,833. In California the FSA also saves state tax, and the answer changes: $5,000 in the FSA leaves $2,298.

2026 rules: the $7,500 FSA and the 50% credit

The 2025 tax law (P.L. 119-21) changed both breaks from 2026. The FSA limit rose from $5,000 to $7,500 per household ($3,750 married filing separately) (§ 129(a)(2); IRS Pub. 15-B). The credit's top rate rose from 35% to 50%, with a second phase-down that starts at $75,000 of adjusted gross income ($150,000 joint) (§ 21(a)(2); draft 2026 Form 2441 instructions).

What didn't change: the $3,000/$6,000 expense limits, and the credit is still nonrefundable, so it can't be more than your federal income tax. None of these amounts is indexed for inflation, so 2027 is the same: a $7,500 FSA and the same rate table. Examples: AGI of $60,000 gets 35%; $90,000 single gets 27%; $180,000 joint gets 27%.

How much a dependent care FSA really saves

FSA money is never taxed: no federal income tax, no Social Security or Medicare (§ 3121(a)(18)), and no state income tax in most states. Your saving is roughly your federal bracket + 7.65% + your state rate, on the amount you put in.

• $150,000 couple, two children, no state tax: the full $7,500 saves about $1,650 of federal tax and $574 of Social Security and Medicare, against a credit of $2,100 on its own.
• $60,000 couple, two children: the 35% credit alone is worth $2,100, but it uses up tax the Child Tax Credit would have covered, so the family keeps $1,840. The FSA lowers their earned income and raises their EITC, so the full FSA leaves $2,963.
• $350,000 couple, one child: pay over the $184,500 Social Security wage base means the FSA saves only 1.45% (or 2.35%) Medicare tax, not 7.65%. The full FSA still wins: $1,976 against $600 from the 20% credit.

The Child Tax Credit and EITC knock-on

The child care credit comes off your tax before the Child Tax Credit. If the two together are more than your tax, the child care credit can push part of the Child Tax Credit into its refundable part, which is capped ($1,700 per child in 2026) and limited to 15% of earnings over $2,500. Families with modest incomes can lose some of the child care credit's value this way. FSA money also lowers earned income, which can raise the EITC in its phase-out range or lower it in the phase-in. The calculator works all of this out. The Child Tax Credit itself is a separate credit; see how it's figured with the Child Tax Credit calculator, and your whole refund with the tax refund calculator.

State taxes and state credits

Most states start from federal wages, so the FSA saves state tax too. But states don't all follow federal tax changes automatically, and some haven't adopted the $7,500. Three to check:

• Pennsylvania excludes dependent care assistance from state income tax since 2023, but its Revenue Department page still describes the exclusion as up to $5,000 (PA DOR). The calculator treats only $5,000 as tax-free for PA until that's updated. Most local earned income taxes follow the state; Philadelphia's wage tax doesn't exclude it (EY).
• California still excludes only $5,000: it hasn't adopted the federal increase (EY). The other $2,500 is taxed as California wages, and the calculator counts that.
• New Jersey doesn't follow the federal rules for cafeteria plans (TB-39(R)), and salary reductions under them are generally NJ wages. The calculator assumes no NJ saving; compare W-2 boxes 1 and 16 to see how your employer treats it.

More than 20 states have their own child care credit, often a percentage of the federal credit (NCSL). New Jersey, for example, gave 10%–50% of the federal credit for 2021–2025 to households with up to $150,000 of NJ taxable income, and it's refundable (NJ Division of Taxation). Because FSA money shrinks the federal credit, it shrinks these too. They aren't in the calculator, so if your state has one, the credit side is worth a bit more than shown.

Choosing your election at open enrollment

• Check your plan's limit. Employers had to amend their plans to allow $7,500; some stayed at $5,000.
• Highly paid? Expect a cap. Plans must pass nondiscrimination tests, and many cut elections for highly compensated employees; the State of New Jersey capped them at $3,600 for 2026 (NJ Pensions and Benefits).
• Employer money counts. Any employer contribution uses up part of the $7,500 and of the credit's limit.
• The limit is per household and per calendar year, even if your plan year isn't. If both spouses have plans, the total for both is $7,500.
• Your election is fixed for the year unless something changes: a birth, a marriage, a spouse starting or stopping work, a child turning 13, or a change of provider or cost (not when the provider is a relative) (Treas. Reg. 1.125-4).
• Divide by your paychecks. $7,500 is about $288 every two weeks or $625 a month.

Choosing a health plan at the same time? Compare health plans, and for health accounts see the HSA vs FSA calculator (a health FSA or HSA is separate from this one). The year-end money checklist covers the other deadlines.

Use it or lose it: how much is safe to elect

A dependent care FSA has no carryover: money not used for care by the end of the plan year is forfeited. Your plan may add a grace period of up to 2½ months to incur costs, and a run-out period to file claims. Unlike a health FSA, you can usually only be reimbursed up to what you've paid in so far, so early-year bills wait for the money to build up.

Elect what you're confident you'll spend: day care you've already booked, not a summer camp you might skip. The calculator shows how much you could leave unspent before the FSA stops beating the credit alone. Watch for a child turning 13 (costs after the birthday don't count), a job change mid-year, or a parent leaving work.

What counts as child care

Costs count if the care lets you (and your spouse) work or look for work, for a child under 13 or a dependent or spouse who can't care for themselves (Treas. Reg. 1.21-1; Form 2441 instructions).

You'll need the provider's name, address and taxpayer ID (Form W-10 is a simple way to ask for it).

Both spouses must work (mostly)

The FSA and the credit can't use more than the lower earner's earned income (§ 129(b); § 21(d)). If one spouse stays home all year, neither break applies. The exception: a spouse who is a full-time student (some part of 5 months) or can't care for themselves is treated as earning $250 a month with one child, or $500 with two or more. Married couples must file jointly to claim the credit, unless they lived apart for the last 6 months of the year; unless you lived apart, married filing separately also halves the FSA limit to $3,750.

How to claim: W-2 box 10 and Form 2441

Your employer reports FSA money (yours and theirs) in box 10 of your W-2. You file Form 2441 with your return either way: Part III shows the FSA money is tax-free and cuts the credit's limit by it, and Part II works out any credit. If you used the grace period, the amount carried into the next year is counted in the year you spend it (2026 Form 2441 instructions, draft).

Common questions

Is the dependent care FSA limit $7,500 in 2026?

Yes. From January 1, 2026 it's $7,500 per household ($3,750 if married filing separately), if your employer's plan allows it. It isn't indexed, so it's $7,500 in 2027 too.

Can I use a dependent care FSA and the child care credit?

Only partly. FSA money cuts the credit's $3,000 or $6,000 limit dollar for dollar. With two or more children and $5,000 in the FSA, $1,000 of costs can still go toward the credit; at $7,500, or with one child and $3,000 or more in the FSA, nothing is left.

Is a dependent care FSA worth it?

Usually, if you're sure to spend the money and earn enough to pay income tax: it saves your bracket plus 7.65% plus state tax. For the example family on this page it's worth $124 more than the credit alone.

Is the child and dependent care credit refundable in 2026?

No. It's nonrefundable, so it can only reduce your income tax to zero. It was refundable only in 2021.

Does summer camp count?

Day camp does, even a specialty camp. Overnight camp doesn't.

What happens if I don't use all my dependent care FSA?

It's forfeited, apart from any grace period your plan offers (up to 2½ months). There's no carryover like a health FSA's.

Can both spouses have a dependent care FSA?

Yes, but the $7,500 limit is for the household. Anything over $7,500 in total becomes taxable.

Can I change my dependent care FSA election mid-year?

Only after a qualifying change, such as a birth, a new provider, a change in the cost or hours of care, or a spouse's job change, and only going forward.
