What the Additional Child Tax Credit Is

The Additional Child Tax Credit (also called the Refundable Child Tax Credit) is the part of the child tax credit that can come back to you as a refund, even if you owe no federal income tax. The regular child tax credit reduces the tax you owe dollar-for-dollar. The additional credit goes further: if the credit is larger than your tax bill, the IRS sends you the difference as a refund.

For 2025, the maximum child tax credit is $2,000 per child under age 17. The additional credit is limited to a smaller amount — it phases in based on your earned income. This means you only get the refundable portion if you earned enough money during the year.

The additional credit exists because families with lower incomes often owe little or no federal tax, so a regular credit would not help them. The refundable portion ensures they still benefit from the credit.

Key Takeaways

  • The additional child tax credit is refundable money from the IRS, separate from the regular child tax credit, and only applies if you have earned income.
  • For 2025, the maximum additional credit is $1,700 per may have access to child, but the exact amount depends on your total earned income for the year.
  • You must have at least $2,500 in earned income to receive any additional credit, and the credit grows as your earned income increases.
  • You claim the additional credit on your federal tax return using Form 1040 and Schedule 8812, not through a separate process.

How Much You Can Receive in 2025

The additional child tax credit for 2025 is calculated as 15 percent of your earned income above $2,500, up to a maximum of $1,700 per child. This means the credit grows gradually as you earn more money.

Here is how it works in practice: if you earned $10,000 in 2025, your earned income above $2,500 is $7,500. Fifteen percent of $7,500 is $1,125. That is the maximum additional credit you can receive, even if you have multiple children. If you have one may have access to child, you would receive $1,125. If you have two may have access to children, you still receive $1,125 total — not $1,125 per child — because the credit is limited by your earned income, not by the number of children.

Once your earned income reaches approximately $13,167, the 15 percent calculation reaches $1,700 per child. At that point, the credit maxes out at $1,700 per may have access to child. Higher earned income does not increase the credit further.

Who Can Claim the Additional Credit

You can claim the additional child tax credit only if you have earned income during the year. Earned income means wages, salaries, tips, net self-employment income, or other compensation you received for work. It does not include investment income, Social Security, unemployment benefits, or child support.

The child must meet the same requirements as for the regular child tax credit: they must be your son, daughter, stepchild, foster child, sibling, or descendant of any of these; they must be under age 17 at the end of 2025; they must be a U.S. citizen, national, or resident alien; and you must claim them as a dependent on your return. The child must also have a valid Social Security number.

You do not need to owe any federal income tax to claim the additional credit. In fact, families with very low income often owe zero tax but still receive a refund through this credit.

The Earned Income Requirement

The additional credit only begins if your earned income is at least $2,500. If you earned less than $2,500 in 2025, you cannot receive any additional credit, even if you have may have access to children and received a regular child tax credit.

Earned income is calculated on your tax return. If you are self-employed, it is your net self-employment income (income minus business expenses). If you are an employee, it is your wages and salaries reported on your W-2 form. If you received income from multiple sources, you add them together.

The $2,500 threshold is the same regardless of how many children you have. Once you cross that threshold, the credit begins to grow at 15 percent of income above $2,500.

How to Claim the Additional Credit on Your Tax Return

You claim the additional child tax credit on your federal tax return using Form 1040 and Schedule 8812 (Credit for Other Dependents). You do not explore for this credit through a separate process or contact the IRS in advance. Instead, you include it when you file your return.

On Schedule 8812, you enter your earned income, the number of may have access to children, and calculate the credit using the worksheet provided with the form. The IRS instructions walk through the calculation step-by-step. If you use tax preparation software, it usually calculates this automatically based on the information you enter.

You must file a federal tax return to claim the credit, even if your income is so low that you would not normally be required to file. Filing is how the IRS processes the refund and sends it to you.

When You Receive the Money

If you claim the additional child tax credit on your return, the IRS processes it like any other refund. If your total refund (including the additional credit) is larger than any tax you owe, the IRS sends you the difference by direct deposit or check, typically within 21 days of accepting your return.

The timing depends on when you file. If you file early in the tax season (January or February), you usually receive your refund faster. If you file closer to the April important date, processing may take longer because the IRS handles a higher volume of returns.

If you owe other debts — such as unpaid student loans, back child support, or state income taxes — the IRS may offset your refund to pay those debts before sending you the remaining balance.

Common Mistakes to Avoid

The most common mistake is forgetting to include Schedule 8812 with your return. If you claim the regular child tax credit but do not file Schedule 8812, you will not receive the additional refundable portion. Always check that Schedule 8812 is attached to your Form 1040 before submitting.

Another mistake is using the wrong Social Security number for a child or listing a child who does not meet the age or relationship requirements. The IRS matches the numbers on your return against its records, and mismatches can delay your refund or reduce the credit you receive.

Some people also overlook earned income from self-employment or gig work. If you drove for a rideshare service, sold items online, or did freelance work, that income counts toward the $2,500 threshold and affects your credit amount. Make sure to include all sources of earned income on your return.

Frequently Asked Questions

Do I get the additional credit for each child, or is it one credit total?

The additional credit is limited by your earned income, not by the number of children. If your earned income generates a $1,125 credit, you receive $1,125 total, whether you have one child or five. However, once your earned income is high enough, the credit maxes out at $1,700 per child, so the number of children does matter at higher income levels.

What if I did not work the entire year?

You can still claim the additional credit based on the earned income you did receive. If you earned $8,000 in six months and then stopped working, you use that $8,000 to calculate your credit. The credit does not require full-year employment.

Can I claim the additional credit if I am claimed as a dependent on someone else's return?

No. If another person claims you as a dependent, you cannot claim the child tax credit or the additional credit for your own children. This usually applies to adult children living with parents. You must be independent on your tax return to claim credits for your children.

Is the additional credit the same as the Child Tax Credit expansion I heard about?

The additional credit is a permanent part of the tax code. Proposals to expand the child tax credit or make it fully refundable are separate policy discussions. For 2025, the additional credit works as described here — 15 percent of earned income above $2,500, up to $1,700 per child.

What if my earned income changes after I file?

You calculate the credit based on your actual earned income for the year shown on your final tax return. If you discover an error after filing, you can file an amended return (Form 1040-X) to correct it and claim any additional credit you missed.
