IRS Publication 5811 – The Child Tax Credit (CTC) is a valuable tax benefit designed to help families offset the costs of raising children. IRS Publication 5811 serves as an educational resource to inform taxpayers about this credit, its eligibility rules, and how to claim it. Whether you’re a parent filing taxes for the first time or looking to maximize your refund, understanding the CTC can lead to significant savings. In this SEO-optimized article, we’ll break down everything you need to know about the Child Tax Credit based on trusted IRS sources, including key details from Publication 5811.
What is the Child Tax Credit (CTC)?
The Child Tax Credit is a non-refundable tax credit that reduces your federal income tax liability dollar-for-dollar for each qualifying child. It’s aimed at supporting families with dependents under the age of 17. IRS Publication 5811 highlights the CTC as a key way for eligible taxpayers to lower their tax bill, even if they don’t typically file a return. Unlike deductions that reduce taxable income, the CTC directly cuts the amount of tax you owe.
If the credit exceeds your tax liability, a portion may be refundable through the Additional Child Tax Credit (ACTC), providing extra financial relief. This makes the CTC particularly beneficial for low- to middle-income families.
Eligibility Requirements for the Child Tax Credit
To claim the CTC, both you (and your spouse if filing jointly) and your child must meet specific criteria outlined in IRS Publication 5811 and related guidelines.
Taxpayer Eligibility
- You must have a valid Social Security Number (SSN) issued for employment in the U.S. before the tax return due date.
- If married filing jointly, your spouse must also qualify.
- No minimum income is required to claim the CTC, but for the refundable ACTC, you need at least $2,500 in earned income.
Qualifying Child Requirements
A qualifying child must:
- Be under 17 years old at the end of the tax year.
- Be your son, daughter, stepchild, foster child, sibling, stepsibling, or a descendant (e.g., grandchild or niece/nephew).
- Not provide more than half of their own financial support.
- Live with you for more than half the year.
- Be claimed as a dependent on your tax return.
- Not file a joint return (unless solely to claim a refund).
- Be a U.S. citizen, national, or resident alien with a valid SSN for employment.
If your dependent doesn’t qualify for the CTC (e.g., over 17), you may be eligible for the Credit for Other Dependents (ODC), worth up to $500 per dependent.
Child Tax Credit Amounts and Phase-Out Thresholds for 2025
For the 2025 tax year (returns filed in 2026), the maximum CTC is $2,200 per qualifying child. The refundable ACTC portion can provide up to $1,700 per child if your tax liability is low.
The full credit is available if your modified adjusted gross income (MAGI) is $200,000 or less ($400,000 for married filing jointly). Above these thresholds, the credit phases out gradually:
- It reduces by $50 for every $1,000 (or fraction thereof) over the income limit.
- Higher-income families may see the credit reduced or eliminated entirely.
| Income Level (Single Filer) | Income Level (Married Filing Jointly) | Maximum CTC per Child |
|---|---|---|
| Up to $200,000 | Up to $400,000 | $2,200 |
| $200,001–$240,000 | $400,001–$440,000 | Partial (phased out) |
| Over $240,000 | Over $440,000 | $0 |
These amounts reflect updates from recent legislation, including the One Big Beautiful Bill Act (OBBBA), which increased the credit to $2,200 starting in 2025.
How to Claim the Child Tax Credit?
Claiming the CTC is straightforward:
- File Form 1040 or 1040-SR.
- Attach Schedule 8812 (Credits for Qualifying Children and Other Dependents).
- List your qualifying children and provide their SSNs.
- Calculate the credit using the worksheet in Schedule 8812 or tax software.
Even if you owe no taxes, file a return to claim the refundable ACTC. Use the IRS Interactive Tax Assistant tool to check eligibility quickly.
Note: If claiming the ACTC or Earned Income Tax Credit (EITC), refunds are delayed until mid-February.
Understanding the Additional Child Tax Credit (ACTC)
The ACTC is the refundable part of the CTC, kicking in when the CTC exceeds your tax bill. For 2025, it’s up to $1,700 per child, but limited to 15% of your earned income over $2,500. This ensures families with lower incomes still benefit, turning the credit into a potential refund.
Recent Changes and Updates to the Child Tax Credit
The CTC saw enhancements in 2025, with the maximum amount rising from $2,000 to $2,200 per child due to legislative adjustments. Inflation adjustments begin in 2026, potentially increasing the credit further. IRS Publication 5811 was updated in December 2025 to reflect these changes and promote awareness among taxpayers.
