IRC §21 · §129 · Form 2441 · OBBB
Child & Dependent Care (2026)
OBBB rewrote both halves — a bigger FSA and a new rate curve for the credit. Here's the honest decision.
What OBBB changed
1. Dependent Care FSA (§129): $5,000 → $7,500
For taxable years beginning after December 31, 2025 (for most people, calendar 2026), the excludable dependent-care benefit rises from $5,000 to $7,500 ($2,500 → $3,750 MFS). It's the first permanent increase since the $5,000 cap was set in 1986 (a one-year $10,500 limit applied only in 2021) — the limit otherwise sat unchanged through four decades of daycare inflation. Your employer's cafeteria plan must be amended to allow elections above $5,000; the raise doesn't happen automatically.
2. §21 credit: new top-loaded rate curve
Pre-OBBB, the credit ran a single flat slope from 35% down to a 20% floor. Starting 2026, the curve starts at 50% for AGI ≤ $15,000, slides to a 35% plateau above $43,000, holds through the middle-class threshold ($75k single / $150k MFJ), then slides again to a 20% floor above $103k / $206k. Expense caps are unchanged: $3,000 for one qualifying person, $6,000 for two or more.

Married filing separately gets no credit unless your spouse did not live in your home for the last 6 months of the year and you paid more than half the cost of keeping up a home the qualifying person lived in for more than half the year (IRC §21(e)(2), (4)). Otherwise married couples must file jointly.
FSA vs credit — two families, two answers
A. High-earner MFJ — $180,000 AGI, 22% bracket, both spouses under the Social Security wage base
Two kids, $8,000 in daycare, considering the max $7,500 FSA election.
- FSA: $7,500 × (22% + 7.65% FICA) = $2,223.75
- Credit only: $6,000 × 27% = $1,620
- Winner: FSA, by $603.75. No credit remains — §21(c) reduces the $6,000 cap by the $7,500 exclusion, so the credit portion is $0.
B. Moderate-earner MFJ — $60,000 AGI, 12% bracket
Two kids, $8,000 in care expenses, same max election modeled.
- FSA: $7,500 × (12% + 7.65%) = $1,473.75
- Credit only: $6,000 × 35% = $2,100
- Winner: the credit, by $626.25. On the 35% plateau the credit outruns the FSA's flat exclusion — and at this income there is real federal liability to absorb it.
Why not showcase the 50% rate? Below roughly $45,000 MFJ, the standard deduction wipes out most or all federal liability — and this credit is nonrefundable, so the headline 50% can be worth $0 in practice. The FSA still saves FICA at any income. Run your real numbers.

The no-double-dip rule (§21(c))
Every dollar you exclude through the dependent-care FSA reduces the credit's expense cap by the same dollar. There is no legal path to run $8,000 of daycare through a $5,000 FSA and claim the full $6,000 credit cap. A worked mechanic:
- Two kids, $8,000 expenses, $7,500 FSA → cap = $6,000 − $7,500 = $0 → credit = $0.
- Two kids, $8,000 expenses, $4,000 FSA → cap = $6,000 − $4,000 = $2,000 → credit = $2,000 × your applicable percentage.
Who qualifies (and what the IRS wants on Form 2441)
- Qualifying person: a dependent under age 13, or a spouse/dependent physically or mentally incapable of self-care who lives with you more than half the year.
- Work-related care. Care must be so you (and your spouse, if MFJ) can work, look for work, or attend school full-time.
- Both spouses have earned income. Creditable expenses cannot exceed the lower-earning spouse's earned income. A stay-at-home spouse (with no earned income) blocks the credit unless they qualify as a student or incapable of self-care.
- Provider information required. Form 2441 asks for each provider's name, address and TIN (SSN or ITIN for an individual, EIN for a business; tax-exempt organizations need only name and address). If a provider won't give it, you can still claim the credit (and the FSA exclusion) by showing due diligence: request Form W-10, keep the request, enter what you know and attach a statement. Paying a sitter in cash doesn't by itself disqualify the care, but you need their details, and you may owe household-employment taxes (see the nanny tax guide).
Open enrollment is when the FSA raise matters
Elect up to the new $7,500 during this fall's open enrollment for 2027, and check that your plan document allows it
The FSA raise only helps if you use it. The higher limit applies for taxable years beginning after December 31, 2025, but your employer's cafeteria plan must be amended before elections above $5,000 are available — ask HR whether the plan document has been updated, and elect the amount you need during open enrollment. Miss the window and you're locked at your election for another plan year unless you hit a qualifying life event.
FAQ
Did the dependent care FSA go up for 2026?
Yes. OBBB (P.L. 119-21) raised the §129 excludable limit from $5,000 to $7,500 ($3,750 MFS) for taxable years beginning after December 31, 2025 (for most people, calendar 2026). It's the first permanent increase since the $5,000 cap was set in 1986 (a one-year $10,500 limit applied only in 2021). Your employer's cafeteria plan must be amended to allow elections above $5,000 — check with HR before assuming your election ceiling moved.
FSA or the credit — which is better?
Higher-income families almost always win with the FSA, as long as their care costs at least equal the election (unused election dollars are generally forfeited), because dollars excluded through payroll escape both federal income tax and FICA: 7.65% on wages up to the Social Security wage base ($184,500 in 2026) and 1.45% above it, plus the 0.9% Additional Medicare Tax on wages above $200,000 ($250,000 of combined wages on a joint return, $125,000 married filing separately; employers withhold it above $200,000 regardless). Below the wage base that is a combined 30%+ benefit for anyone in the 22% bracket or above. Lower-income families with an applicable percentage near 50% often do better claiming the credit because it can outrun the FSA's flat exclusion. The calculator runs both sides for your numbers; it leaves out the 0.9%.
Can I use both the FSA and the credit?
Only on separate dollars. §21(c) reduces the credit's $3,000 / $6,000 expense cap dollar-for-dollar by any amount you excluded through the FSA. A max $7,500 FSA election with two kids leaves $0 of creditable expenses, so the credit zeroes out. A partial election (say $4,000 with $8,000 of actual expenses) leaves $2,000 in the cap for the credit to work on.
Is the dependent care credit refundable?
No. The §21 credit is nonrefundable — it can offset your federal income tax to zero but cannot generate a refund on its own. Families with no federal tax liability get no benefit from the credit; the FSA, by reducing wages, still cuts FICA and state tax where applicable.
