What the Child Tax Credit Actually Pays

The Child Tax Credit is a federal tax reduction worth up to $2,000 per child under age 17. The IRS sends this money to you in one of two ways: as a reduction on your tax bill when you file, or as monthly advance payments deposited directly to your bank account. Most families receive a combination of both.

The credit phases out as your income rises. For 2024, the phase-out begins at $400,000 for married couples filing jointly and $200,000 for single filers. Once your income exceeds these thresholds, the credit decreases by $50 for every $1,000 (or fraction thereof) over the limit. This means higher-income families may receive a partial credit or none at all.

You do not have to owe taxes to receive this credit. Even if your tax bill is zero, you may still receive a payment. This is called a refundable credit, and it is one of the largest cash transfers the federal government makes to families with children.

Key Takeaways

  • The Child Tax Credit is worth up to $2,000 per child under 17, and you can receive it as monthly payments, a lump sum at tax time, or both.
  • You must have a valid Social Security number for each child, a may have access to relationship (parent, guardian, or legal custodian), and the child must live with you for more than half the year.
  • The credit begins to phase out at $400,000 for married couples and $200,000 for single filers, reducing by $50 for every $1,000 over that amount.
  • If you received advance payments in 2024, you must report them when you file your 2024 tax return, even if the amount was incorrect.
  • You claim the credit on your federal tax return using Form 1040 and Schedule 8812, or through tax software that walks you through the questions.

Who Can Claim a Child as a Dependent

To claim the Child Tax Credit, the child must be your son, daughter, stepchild, foster child, sibling, or a descendant of any of these (such as a niece or nephew). The child must also be under age 17 at the end of the tax year, have a valid Social Security number, and live with you for more than half the year. Temporary absences for school, medical care, or military service do not count against this requirement.

You must also be the child's parent, stepparent, legal guardian, or legal custodian. If multiple adults could claim the same child, only one person can claim that child on their tax return. If you and another parent share custody, the parent with primary custody usually has the right to claim the child, unless you have a written agreement saying otherwise.

The child must be a U.S. citizen, national, or resident alien with a valid Social Security number issued by the Social Security Administration. A tax identification number (ITIN) does not count for this credit.

Income Limits and How the Phase-Out Works

The credit begins to reduce once your modified adjusted gross income (MAGI) exceeds $400,000 for married couples filing jointly, $200,000 for single filers, and $200,000 for heads of household. Your MAGI is usually the same as your adjusted gross income (AGI) shown on your tax return.

For every $1,000 of income over the threshold (or any part of $1,000), the credit decreases by $50. This means if you earn $400,001 as a married couple, your credit drops by $50. If you earn $401,000, it drops by $100. The reduction continues until the credit reaches zero.

Example: A married couple with two children and MAGI of $420,000 would normally receive $4,000 (two children × $2,000). Their income is $20,000 over the $400,000 threshold. That $20,000 rounds up to 20 increments of $1,000, so the credit reduces by $1,000 (20 × $50). They would receive $3,000 instead of $4,000.

Advance Payments Versus Claiming at Tax Time

Starting in 2021, the IRS began sending advance monthly payments of the Child Tax Credit to may be able to access families. These payments went out on the 15th of each month from July through December. Each payment was half of the estimated annual credit, spread across six months.

When you file your 2024 tax return, you must report how much you received in advance payments. The IRS will compare this to the full credit you are may have access to to based on your actual 2024 income. If you received more than you should have, you may owe money back when you file. If you received less, you get the difference as a refund or credit against other taxes owed.

You can also choose not to receive advance payments and claim the full credit when you file your return. To opt out of advance payments, you would have needed to use the IRS's Child Tax Credit Update Portal before the payment period ended. For future years, check the IRS website in late spring to see if you can adjust your payment elections.

How to Claim the Credit on Your Tax Return

You claim the Child Tax Credit on Form 1040 (the main federal income tax form) and Schedule 8812 (Credits for may have access to Children and Other Dependents). You will need the child's full legal name, date of birth, and Social Security number for each child you are claiming.

If you use tax software, the program will ask you questions about each child and automatically fill in the correct forms. You will enter the child's name, birth date, and SSN, confirm they lived with you for more than half the year, and verify your relationship to them. The software calculates the credit based on your income and the number of children.

If you file by paper, you must complete Schedule 8812 and attach it to your Form 1040. You list each child separately with their information and relationship to you. The IRS will verify the Social Security numbers you provide, so accuracy is important — mismatched names or numbers can delay your refund.

What Happens If Your Income Changes During the Year

If you received advance payments based on your 2023 income but your 2024 income was higher, you may have to repay some or all of the advance payments when you file your 2024 return. The amount you owe back depends on how much higher your income was and how many children you claimed.

There are limits on how much you have to repay. For 2024, if your MAGI is between $200,000 and $400,000 (depending on your filing status), the maximum repayment is $50 per child. If your MAGI exceeds $400,000 for married couples or $200,000 for single filers, there is no repayment limit — you may owe back the full amount of overpayment.

If your income dropped during the year, you may have received less in advance payments than you were may have access to to. When you file your return, you will receive the difference as a refund or as a credit against other taxes you owe. This is one reason it is important to report your actual 2024 income accurately on your tax return.

Frequently Asked Questions

Can I claim the Child Tax Credit if I am not the child's biological parent?

What if the child's other parent also wants to claim them?

Only one person can claim the same child on their tax return. If you share custody, the parent with primary custody usually has the right to claim the child.

Do I have to repay advance payments if my income went up?

It depends on how much your income increased. If your MAGI is between $200,000 and $400,000 (for married couples), the maximum repayment is $50 per child. If your MAGI exceeds those thresholds, there is no cap on repayment — you may owe back the full overpayment. Check your tax return to see the exact amount.

What if I did not receive advance payments but think I should have?

You can still claim the full Child Tax Credit when you file your tax return if you meet the requirements. You do not need to have received advance payments to get the credit. File your return with the child's information, and the IRS will calculate the credit you are owed.

Can I claim the credit for a child who does not have a Social Security number?

No. The child must have a valid Social Security number issued by the Social Security Administration. A tax identification number (ITIN) does not count. If your child does not have an SSN, you can apply for one through the Social Security Administration before filing your return.
