Family Tax Credit Calculator 2026
Every 2026 family credit computed together and in the order Form 1040 applies them — Child Tax Credit, Credit for Other Dependents, the refundable Additional Child Tax Credit, the Child and Dependent Care Credit at its new OBBBA rate, the Earned Income Credit on its actual curve, and the adoption credit.
Quick answer
This computes each 2026 family credit from the published figures, applies them in Form 1040 order, and separates what reduces your tax from what is paid to you. The Earned Income Credit is computed on the IRC § 32 phase-in and phase-out curve rather than reported as an eligibility flag.
What this includes
- Child Tax Credit at $2,200 per child, with the $50-per-$1,000 phase-out from $200,000 ($400,000 joint)
- Credit for Other Dependents at $500, and the refundable Additional Child Tax Credit capped at $1,700 per child
- The Child and Dependent Care Credit at the OBBBA rate — 50% falling to 20% — including the dependent-care FSA offset
- The Earned Income Credit computed on the 2026 curve, with the $12,200 investment-income cliff
- The adoption credit at $17,670 per child, with the $5,120 refundable portion new for 2026
- Filing-status restrictions, the SSN requirement, and the earned-income tests each credit turns on
What it excludes
- The relationship, residency and support tests that decide whether a child qualifies at all
- Education credits, the saver's credit and the premium tax credit
- State credits, several of which mirror the federal EITC at a percentage of it
- Whether someone else is claiming the same child, which no calculator can see
The 2026 rule most people get wrong: The Additional Child Tax Credit is not a bonus on top of the Child Tax Credit — it is the part your tax could not absorb. And two 2026 figures are commonly published as 2025 ones: the investment-income cliff is $12,200, not $11,950, and the care credit's top rate is 50%, not 35%.
How these figures are calculated · IRS Rev. Proc. 2025-32 · IRS — Earned Income Tax Credit · Tax data last verified
- You, your spouse and every qualifying child have a Social Security number valid for employment, issued by the due date of the return.
- You lived in the United States for more than half the year (or meet the military or clergy exception).
- You are not the qualifying child of another person, and no one else is claiming the same child.
- Each qualifying child is under 19 at year end — under 24 if a full-time student, any age if permanently and totally disabled — is related to you, and lived with you in the United States for more than half the year.
The 2026 Earned Income Credit, in full
| Qualifying children | Maximum credit | Reached at | Phase-out starts | Fully gone at | Rates |
|---|---|---|---|---|---|
| No children | $664 | $8,680 | $10,860$18,140 joint | $19,540$26,820 joint | 7.65% in7.65% out |
| One child | $4,427 | $13,020 | $23,890$31,160 joint | $51,593$58,863 joint | 34.00% in15.98% out |
| Two children | $7,316 | $18,290 | $23,890$31,160 joint | $58,629$65,899 joint | 40.00% in21.06% out |
| Three or more | $8,231 | $18,290 | $23,890$31,160 joint | $62,974$70,244 joint | 45.00% in21.06% out |
The phase-out is measured on the greater of adjusted gross income and earned income, so a deduction cannot rescue the credit for someone whose gross earnings are already past the last column. Separately, investment income above $12,200 disqualifies the credit outright — a cliff, not a taper, and the figure most often quoted a year out of date.
What a family of two children gets around each threshold
| Income | What changes here | Care credit | CTC used | ACTC | EITC | Total |
|---|---|---|---|---|---|---|
| $15,000 | Care credit still at 50% | —50% | — | $1,875 | $6,000 | $7,875 |
| $18,290 | EITC reaches its maximum | —48% | — | $2,369 | $7,316 | $9,685 |
| $31,160 | EITC phase-out begins | —41% | — | $3,400 | $7,316 | $10,716 |
| $45,000 | Care credit has fallen to its 35% floor | $1,28035% | — | $3,400 | $4,401 | $9,081 |
| $65,899 | EITC fully phased out | $2,10035% | $1,448 | $2,952 | — | $6,500 |
| $150,000 | Care credit starts its second phase-down | $2,10035% | $4,400 | — | — | $6,500 |
| $250,000 | Well below the Child Tax Credit phase-out | $1,20020% | $4,400 | — | — | $5,600 |
Two shapes are worth noticing. The Additional Child Tax Credit falls to nothing as income rises — not because the family lost a credit, but because their tax grew large enough to absorb it all. And the care credit's rate steps down long before the Child Tax Credit's phase-out begins, so a family well under $400,000 is already past every care-credit threshold.
The dependent-care FSA and the care credit
A § 129 dependent-care FSA lets you pay for care with money that never appears in your income. The Child and Dependent Care Credit gives you a percentage of care costs back. Form 2441 Part III reconciles them: every dollar excluded through the FSA reduces the credit's $3,000 or $6,000 expense limit, dollar for dollar. Put the full $7,500 through an FSA — the 2026 limit, raised by OBBBA from $5,000 — and there is nothing left for the credit.
Which is better depends on your rate. The FSA saves income tax at your marginal rate and avoids Social Security and Medicare tax, which the credit does not — worth an extra 7.65% for most earners. A household at 22% therefore saves close to 30% through the FSA against a 20% credit. Lower down, where the credit rate is 50%, the credit usually wins.
There is a real trap in the FSA: it is use-it-or-lose-it, and the higher 2026 limit makes over-electing more expensive. Money forfeited at year end has bought you nothing and has also shrunk the credit you could have claimed instead.
The conditions no calculator can check for you
- Age. Under 17 at the end of the year for the Child Tax Credit. Under 19 for the Earned Income Credit — under 24 if a full-time student, any age if permanently and totally disabled. A child who turns 17 during the year drops from the $2,200 credit to the $500 Credit for Other Dependents, which is the single most common reason a refund falls.
- Identification. The Child Tax Credit and the Earned Income Credit both require a Social Security number valid for employment, issued by the due date of the return. An ITIN supports only the Credit for Other Dependents.
- Residency. The child must have lived with you for more than half the year, and for the Earned Income Credit that has to be inside the United States.
- Relationship. Your child, stepchild, foster child, sibling, half-sibling or step-sibling, or a descendant of any of them.
- Nobody else. If two people could claim the same child, the tie-breaker rules in IRC § 152(c)(4) decide, and only one of you can claim any of these credits for that child.
- Support and joint returns. The child must not have provided more than half their own support, and must not be filing a joint return except to claim a refund.
