Child Tax Credit: Eligibility and How to Claim It
A family with a child may qualify for a federal tax break even if it does not usually have to file a return. For a 2025 tax return, Child Tax Credit eligibility depends on federal rules and your household’s details. This guide helps parents and caregivers check whether a child and taxpayer may qualify, understand related credits, and prepare to claim them.
You may need to file even when your income is low enough that a return is not usually required. Filing can be the step that lets you claim a credit or receive a refund. Modified adjusted gross income (MAGI) is adjusted gross income recalculated with certain tax adjustments for a particular tax rule.
The rules can differ by tax year, and the right answer may depend on details such as where a child lived. Check the tax year printed on the return before applying any eligibility rule, because credit rules can change by year.
What Is the Child Tax Credit Worth?
For tax year 2025, the Child Tax Credit is worth up to $2,200 per qualifying child. Up to $1,700 per qualifying child may be refundable through the Additional Child Tax Credit (ACTC), the refundable portion of the CTC.
The CTC itself reduces the income tax you owe. A refundable ACTC amount may add to your refund when the credit is greater than your tax bill. Refundable means you may receive some credit even when you owe no federal income tax.
| Measure | 2025 amount | What it means |
|---|---|---|
| Maximum CTC | Per qualifying child | Up to $2,200 |
| Maximum ACTC | Per qualifying child | Up to $1,700 |
| Minimum earned income for ACTC | Taxpayer income | At least $2,500 |
To qualify for the ACTC, you generally need at least $2,500 in earned income. The refundable amount cannot exceed $1,700 per qualifying child. Your earned income and other tax details affect the final amount.
The Child and Dependent Care Credit helps pay for eligible care expenses that let you work or look for work. The CTC is based on qualifying children, not care costs, and a family may qualify for both.
Treat the ACTC’s $1,700 limit as a ceiling, not a promised refund. Your earned income and tax details determine whether you receive the maximum.
A tax credit differs from a deduction because it lowers tax owed rather than lowering the income used to calculate tax. When comparing benefits, keep care expenses separate from the child-based credit and follow each credit’s rules.
Families often have a mix of tax withheld from paychecks and credits on a return. The CTC and ACTC each play a different role in that final calculation.
Who Meets Child Tax Credit Eligibility Rules?
A parent or caregiver may qualify when the child and taxpayer both meet federal rules, not simply because the child is part of the household. Eligibility depends on filing and identification rules for the taxpayer, plus qualifying-child rules for the child.
Check each condition on its own; being a parent does not automatically qualify you. A child’s age, living arrangement, and relationship to you can each affect the result. Income and identification rules can also apply.
The IRS Interactive Tax Assistant can help screen your situation. It asks about filing status, whether you can be claimed as a dependent, and your date of birth.
The online tool is designed for taxpayers who were U.S. citizens or resident aliens for the entire tax year. Extra limits apply to spouses filing jointly, so the tool may not fit every household.
Its estimated completion time is 10 minutes. An eligibility calculator can help organize the facts, but it does not replace the tax return’s own rules.
Use the IRS Interactive Tax Assistant as a screening tool, then verify the result against the return instructions for the relevant tax year.
Which Children Qualify for the Credit?
A qualifying child must pass several tests, including relationship, age, residence, and dependency rules. For 2025, the child generally must be under 17 at year-end and meet each federal test.
Relationship and age requirements
A qualifying child may be your son or daughter, stepchild, or eligible foster child. A brother or sister may qualify, as may a descendant such as a grandchild, niece, or nephew.
The child generally must be under age 17 at the end of the tax year. A child who turns 17 during 2025 does not meet this age test for the CTC.
Where the child lived during the year
The child generally must have lived with you for more than half the year. Time away for school, vacation, medical care, military service, or similar reasons can count as time lived together.
A temporary absence does not always change the child’s home for tax purposes. The facts behind the absence matter, including whether the child was expected to return.
Support, dependency, and filing conditions
You generally must claim the child as your dependent. The child also generally cannot have paid more than half of their own support during the year.
A child generally cannot file a joint return and remain your qualifying child. An exception may apply when the child files only to claim a refund of withheld or estimated taxes.
Use this six-point check before claiming a child:
- Relationship: the child meets an allowed family or foster relationship.
- Age: the child meets the under-17 rule at year-end.
- Residence: the child lived with you for more than half the year.
- Dependency: you can claim the child as a dependent.
- Support: the child did not provide more than half of their own support.
- Status: the child is a U.S. citizen, U.S. national, or U.S. resident alien.
The child must meet the citizenship or residency rule as well as the other tests. Keep records of the child’s living arrangements when temporary absences or a midyear change in household could affect the residence test.
How Do Income and Social Security Number Rules Work?
For tax year 2025, the full credit is available up to $200,000 in annual income, or $400,000 for married couples filing jointly. A partial credit may remain above those limits.
The income phaseout uses modified adjusted gross income (MAGI), not simply the amount of earned income from work. MAGI starts with adjusted gross income, then adds certain tax adjustments for the rule being applied.
Earned income is pay from work or other qualifying work income. It matters for the ACTC, while MAGI helps determine whether income reduces the CTC.
The taxpayer claiming the credit, or at least one spouse on a joint return, needs a Social Security number (SSN) valid for employment in the United States. Each child claimed for the CTC also needs a qualifying SSN.
The SSN must be issued by the return due date, including extensions. An ITIN is not a substitute for the child’s SSN for the CTC or ACTC.
A child with an Individual Taxpayer Identification Number (ITIN) rather than an SSN cannot qualify for the CTC or ACTC under this rule. The number type can matter even when the child meets other tests.
Confirm that every required SSN was issued by the return due date, including any extension.
Can Another Dependent Qualify for a Separate Credit?
A dependent who does not meet the CTC rules may still qualify for the nonrefundable Credit for Other Dependents (ODC). The ODC can be worth up to $500 per dependent.
The ODC may cover a child who fails one CTC requirement or a qualifying relative who depends on you. The credit reduces tax owed, but it cannot create or increase a refund by itself.
The ODC begins to decrease when adjusted gross income exceeds $200,000, or $400,000 for married couples filing jointly. These thresholds refer to adjusted gross income, not the CTC’s MAGI calculation.
A dependent may use an SSN, ITIN, or Adoption Taxpayer Identification Number (ATIN) for the ODC. That gives some families another credit option when a dependent lacks the SSN required for the CTC.
Check the dependent’s identification number separately, since the ODC accepts more types of taxpayer identification than the CTC does.
How Do You Claim the Child Tax Credit?
To claim the federal CTC, enter the eligible child on Form 1040 and complete Schedule 8812. The CTC and ODC use Form 1040 with Schedule 8812.
- Gather identifying information for the taxpayer, spouse, children, and other dependents.
- Enter eligible children and dependents on Form 1040.
- Complete Schedule 8812 for the CTC, ACTC, or ODC.
- Review the return and attach any required schedules before filing.
| Situation | Form | Where it goes |
|---|---|---|
| CTC, ACTC, or ODC | Form 1040 and Schedule 8812 | Attach Schedule 8812 to Form 1040 |
| Child and Dependent Care Credit | Form 2441 | Attach to Form 1040, 1040-SR, or 1040-NR |
| Prior CTC or ACTC reduction or denial | Form 8862 | File when required to claim again |
The Child and Dependent Care Credit goes on Form 2441, attached to Form 1040, Form 1040-SR, or Form 1040-NR. Keep care expenses and provider details with your tax records.
For 2023, the federal care credit generally used a 20%-35% rate. Its expense limits were $3,000 for one qualifying individual or $6,000 for two or more.
If the IRS previously reduced or denied a CTC or ACTC claim, you may need Form 8862 to claim it again. If a previous claim was reduced or denied, check whether Form 8862 is required before filing again.
How Do Custody and Competing Claims Affect Eligibility?
Only one person may claim a child for the listed federal child-related credits and benefits for a tax year. The one-person rule covers the EITC, CTC, ACTC, ODC, Head of Household status, and dependent-care benefits.
When parents do not file jointly, a custody schedule can affect who claims the child. A valid release of a claim may also change who can claim a dependent.
If a child lived with both parents for the same amount of time, the parent with the higher adjusted gross income generally may claim the child as a qualifying child. This tie-breaker applies when the parents do not file a joint return.
Use the actual custody arrangement and federal rules, not just a written schedule or informal agreement. The parent who claims a child may affect more than one tax benefit, so check the instructions for each relevant return.
Compare the child’s actual nights with each parent before applying the equal-time rule.
Which Other Tax Credits Can Families Claim?
Families may qualify for the EITC or the Child and Dependent Care Credit in addition to the CTC. The EITC depends on earned income, filing status, and the number of qualifying children.
EITC income limits and qualifying children
For tax year 2026, married couples filing jointly may qualify with income up to $26,820 with no qualifying children. The limits rise to $58,863 with one, $65,899 with two, and $70,224 with three or more.
The EITC qualifying-child age rule generally requires a child to be under 19. A full-time student may qualify when under 24, and a child with a permanent disability may qualify at any age.
The child generally must also have lived in the United States with you for more than half the year. The table shows income limits and maximum credits for single or head-of-household filers.
| Qualifying children | 2025 single/HOH income limit | 2026 single/HOH income limit | 2025 maximum EITC | 2026 maximum EITC |
|---|---|---|---|---|
| Zero | $19,104 | $19,540 | $649 | $664 |
| One | $50,434 | $51,593 | $4,328 | $4,427 |
| Two | $57,310 | $58,629 | $7,152 | $7,316 |
| Three or more | $61,555 | $62,974 | $8,046 | $8,231 |
Married couples filing jointly have higher 2025 income limits: $26,214 with no qualifying children, then $57,554, $64,430, and $68,675 for one, two, or three or more.
Care expenses and the Child and Dependent Care Credit
For tax year 2026, the care credit covers 20%-50% of eligible care expenses, subject to applicable expense limits. For 2025, expenses are limited to $3,000 for one qualifying individual or $6,000 for two or more.
A qualifying child for this credit must be your dependent and under age 13 when care was provided. Care generally must let you and, for a joint return, your spouse work or look for work.
Expenses generally cannot exceed the lower-earning spouse’s earned income. Check these three points:
- Work-related care: care lets you work or actively look for work.
- Qualifying individual: the person meets the care credit’s rules.
- Earned-income limit: expenses generally do not exceed the lower spouse’s earned income.
For 2024, the federal credit generally used a 20%-35% rate and expense limits of $3,000 for one qualifying individual or $6,000 for two or more.
Choosing credits that address different costs
The CTC addresses qualifying children, while the care credit offsets eligible work-related care expenses. The EITC supports workers with low-to-moderate income who meet its rules.
The 2024 care-credit percentage was 20%-35%, with $3,000 or $6,000 in eligible expenses. The 2026 percentage range is 20%-50%, subject to that year’s applicable expense limits.
Match care expenses to the care credit and do not count the same expense toward another tax benefit when the rules prohibit it.
When Will the Credit Affect Your Refund?
A return claiming the EITC or ACTC cannot receive its refund before mid-February, and the hold applies to the whole refund. The delay is not limited to the amount tied to either credit.
The IRS must wait until mid-February to issue refunds to taxpayers claiming the EITC. The same wait applies to ACTC claims, even when other parts of the refund come from tax withheld.
Use Where’s My Refund to check your personalized refund date. The tool updates once a day, so a new status may not appear each time you check it.
A $10,000 refund can combine refundable credits with federal tax withheld from paychecks or estimated tax payments made during the year. No single credit promises a refund of that size.
Your refund reflects the full return, including tax paid and credits you can claim. Check Where’s My Refund in mid-to-late February for the personalized status rather than estimating a date from the credit amount.
How Has the Credit Changed for 2025 and 2026?
The Child Tax Credit began in 1997 at $400 per child under age 17. Its current 2025 amount is not the same as the temporary expansion used in 2021.
Earlier changes to the credit
The credit’s history includes three key changes:
- 1997: The credit started at $400 for each child under age 17.
- 1999: The amount increased to $500 per child.
- 2021: A temporary expansion raised the maximum to $3,600 for children under 6 and $3,000 for children ages 6-17.
The up-to-$3,600 amount applied temporarily in 2021 for children under 6. It was not the general CTC amount for 2025.
What to know about tax year 2026
For tax year 2025, the CTC is worth up to $2,200 per qualifying child. Beginning in 2026, the amount is adjusted for inflation.
An inflation adjustment is not a repeat of the temporary 2021 expansion. It changes the amount under the current rule rather than restoring the earlier temporary amounts.
The 2021 expansion was temporary, so its higher amounts do not set the general credit for later tax years.
For a 2026 return, the inflation adjustment affects the credit amount, while the temporary expansion remains a separate past change. Check the amount and rules for the specific tax year on the return you are filing, rather than relying on a past temporary expansion.
Conclusion
A careful eligibility check can help you claim the credits that match your household. Confirm the tax year first, then review the taxpayer’s and child’s details against that year’s federal rules.
Gather identification records and income documents before preparing your return. Use the correct federal forms and schedules for the credits you plan to claim.
Gather your documents and complete the correct return and schedules before submitting your claim.
