Who Qualifies for the 2025 Child Tax Credit
Both the taxpayer and the child must meet specific requirements to claim the credit.
| Requirement | Details |
|---|---|
| Age | Child must be under age 17 at the end of December 31, 2025. A child who turns 17 in 2025 does not qualify. |
| Relationship | Son, daughter, stepchild, foster child, sibling, step-sibling, half-sibling, or a descendant of any of these (grandchild, niece, nephew) |
| Residence | Child must have lived with you for more than half of 2025. Exceptions exist for temporary absences such as school, vacation, or medical care. |
| Support | Child must not have provided more than half of their own financial support during the year |
| Citizenship | Child must be a US citizen, US national, or US resident alien |
| Social Security Number | Child must have a valid Social Security number issued before the due date of your return including extensions |
| Dependent status | Child must be claimed as your dependent on your return. Generally only one taxpayer can claim a child. |
| Income phase-out | Credit reduces by $50 for every $1,000 of MAGI above $200,000 (single) or $400,000 (MFJ) |
How the Additional Child Tax Credit (ACTC) Works
The Child Tax Credit first reduces your tax liability. If the credit exceeds your tax, up to $1,700 per child may be refunded to you as the Additional Child Tax Credit.
Family with 2 children, $45,000 earned income, $2,500 federal income tax
How the ACTC is calculated: The refundable ACTC is the lesser of (a) the unused CTC remaining after reducing tax to zero, or (b) 15% of your earned income above $2,500. The maximum refundable amount per child is $1,700 in 2025. You claim the ACTC on Schedule 8812.
Income Phase-Out: When the Credit Reduces
The credit reduces by $50 for every $1,000 (or fraction thereof) of modified adjusted gross income above the threshold. The table below shows how the credit shrinks at different income levels for a single filer with two qualifying children (maximum credit $4,000).
| MAGI (Single Filer) | Amount Over $200K Threshold | Credit Reduction | Credit Remaining (2 children) |
|---|---|---|---|
| $200,000 or below | $0 | $0 | $4,000 (full credit) |
| $210,000 | $10,000 | $500 | $3,500 |
| $220,000 | $20,000 | $1,000 | $3,000 |
| $230,000 | $30,000 | $1,500 | $2,500 |
| $240,000 | $40,000 | $2,000 | $2,000 |
| $260,000 | $60,000 | $3,000 | $1,000 |
| $280,000 | $80,000 | $4,000 | $0 (fully phased out) |
| Filing Status | Phase-Out Starts | Credit Fully Gone At |
|---|---|---|
| Single, Head of Household | $200,000 MAGI | ~$240,000 (1 child), higher for more children |
| Married Filing Jointly | $400,000 MAGI | ~$440,000 (1 child), higher for more children |
| Married Filing Separately | $200,000 MAGI | ~$240,000 (1 child) |
| Phase-out rate | $50 reduction per $1,000 over threshold | Each additional child adds $2,000 to the phase-out range |
Planning tip: If your MAGI is close to the phase-out threshold, pre-tax retirement contributions (401k, IRA, SEP-IRA) reduce MAGI and can preserve more of the credit. A $5,000 traditional IRA contribution by a single filer earning $205,000 drops their MAGI to $200,000, potentially saving $250 in Child Tax Credit they would otherwise lose.
Child Tax Credit in Practice: A Family of Four
Here is how the 2025 Child Tax Credit and Additional Child Tax Credit work for a real household scenario.
| Item | Married Filing Jointly, 2 Kids |
|---|---|
| Combined gross income | $95,000 |
| Standard deduction (MFJ) | − $30,000 |
| Taxable income | $65,000 |
| Federal tax before credits (est.) | ~$7,490 |
| Child Tax Credit (2 children × $2,000) | − $4,000 |
| Federal tax after Child Tax Credit | ~$3,490 |
| MAGI check — phase-out starts at $400,000 MFJ | No phase-out applies |
| Effective federal tax rate (on gross income) | ~3.7% |
What if they owe less than $4,000? Suppose their tax before credits was only $2,800. The Child Tax Credit first reduces that to $0. The remaining $1,200 of unused credit can potentially be refunded as the Additional Child Tax Credit (ACTC), up to the $1,700 per-child refundable limit. In this case, they would receive a $1,200 refund from the ACTC — money back even though they owe $0 in federal income tax.

Child Tax Credit 2025: Key Takeaways
The 2025 Child Tax Credit is one of the most valuable credits available to families with children. Here's what matters most when you file your 2025 return in 2026:
The credit is worth up to $2,000 per qualifying child under age 17. Up to $1,700 of that is refundable — meaning you can get it back as a refund even if you owe no tax — through the Additional Child Tax Credit calculated on Schedule 8812. The non-refundable portion first offsets your federal income tax dollar-for-dollar.
Income limits apply: the credit begins phasing out at $200,000 MAGI for single filers and $400,000 for married couples filing jointly, reducing by $50 per $1,000 over the threshold. For most families earning below these thresholds, the full credit amount is available for each qualifying child.
The child must be under 17 on December 31, 2025, have a valid Social Security number, have lived with you more than half the year, and be claimed as your dependent. Only one taxpayer can claim each child.
Looking ahead to 2026: The One Big Beautiful Bill Act, signed July 4, 2025, made the Child Tax Credit permanent and raised the maximum to $2,200 per child starting with tax year 2025. If your 2025 return benefits from $2,000 per child, your 2026 return (filed in 2027) will reflect the updated $2,200 amount. See our 2026 Child Tax Credit guide for full details.
