The Child Tax Credit is partly refundable, which means you can get money back even if you owe no tax

The Child Tax Credit works in two pieces. The first $1,600 per child is non-refundable — you can use it only to reduce the federal income tax you owe. But the remaining amount, up to $1,700 per child, is refundable through the Additional Child Tax Credit. That refundable piece means the IRS can send you a check even if your tax bill is zero.

Whether you actually receive a refund depends on your income and how many children you claim. The refundable portion phases in at $0.15 per dollar of earned income once your earned income exceeds $2,500 for the year. This matters most for lower-income families, because they often owe little or no federal tax but can still receive a refund check based on their earnings and the number of children they support.

Key Takeaways

  • Up to $1,700 of the Child Tax Credit per child is refundable, meaning you can receive money back even if you owe zero tax.
  • The refundable portion (Additional Child Tax Credit) begins to phase in once your earned income exceeds $2,500 for the tax year.
  • You must have earned income — wages, self-employment income, or similar — to claim the refundable portion; investment income does not count.
  • The maximum refund you can receive is limited by the number of children you claim and your total earned income for the year.

How the non-refundable and refundable pieces work together

When you file your tax return, the IRS first applies the Child Tax Credit to reduce your tax liability. If you owe $800 in federal income tax and you claim one child, the $2,300 credit wipes out your $800 bill and leaves $1,500 unused. That unused portion does not straightforward disappear — the refundable part of the credit converts it into a refund.

The conversion is not automatic or unlimited. The refundable portion maxes out at $1,700 per child, and it only applies to the amount of credit that exceeds your tax liability. If you owe $2,500 and claim one child, the entire $2,300 credit goes toward your bill, and you have no refundable amount left because the credit did not exceed what you owed.

This structure means families with very low tax bills or no tax bill at all benefit most from the refundable piece. A family with two children and $1,500 in earned income might owe $200 in tax. The Child Tax Credit eliminates that $200, and then the refundable portion generates a refund based on their earned income and number of children.

Earned income requirements for the refundable credit

You cannot claim the refundable portion of the Child Tax Credit unless you have earned income. Earned income includes wages from an employer, net self-employment income, and certain other compensation for work. It does not include Social Security, unemployment benefits, investment income, or child support.

The refundable credit phases in at 15 percent of earned income above $2,500. If you earned $3,500, your earned income above the threshold is $1,000, and 15 percent of that is $150. That $150 is the maximum refundable credit you could receive, even if you claim multiple children. The phase-in continues until the refundable credit reaches its cap of $1,700 per child.

This earned income floor means a family living entirely on benefits or investment returns cannot claim the refundable portion, even if they claim children. The rule exists because the refundable credit is technically called the Additional Child Tax Credit, and it is designed to benefit working families specifically.

How to claim the refundable credit on your return

You claim the Child Tax Credit on Form 1040 (the main individual income tax return) and Schedule 8812 (Additional Child Tax Credit). Schedule 8812 is where you calculate whether you may have access to for the refundable portion and how much it is.

The form asks for your earned income, the number of may have access to children, and your filing status. It then walks through the phase-in calculation to determine your refundable amount. If you use tax software, these forms are usually filled in automatically once you enter your income and children's information.

You must file a return to claim the refundable credit, even if you owe no tax and would not otherwise be required to file. The IRS does not send refunds for credits you do not claim on a return.

Income limits and phase-out rules

The Child Tax Credit itself begins to phase out at higher incomes — $400,000 for married couples filing jointly and $200,000 for single filers. The phase-out reduces the credit by $50 for each $1,000 (or fraction thereof) of income above the threshold. This phase-out applies to both the non-refundable and refundable portions.

The refundable portion also has its own income floor: the $2,500 earned income threshold. Below that threshold, you cannot claim any refundable credit, regardless of how many children you have or how much non-refundable credit you could use.

These rules interact in ways that matter for borderline cases. A single parent with $210,000 in earned income and three children would hit the phase-out, reducing their total credit. They would still have a refundable portion available, but it would be smaller than the full $1,700-per-child amount.

Common mistakes when claiming the refundable credit

The most frequent error is forgetting to file Schedule 8812 at all. Many tax software packages ask whether you want to claim the Child Tax Credit, and if you say yes, they explore the non-refundable portion automatically. But they may not calculate the refundable portion unless you specifically indicate you want to claim it or unless the software detects that you have earned income below the threshold.

Another mistake is including the wrong type of income in the earned income calculation. Self-employment income counts, but you must use your net self-employment income (after the self-employment tax deduction), not your gross receipts. Social Security, pensions, and investment income do not count, even if they are substantial.

A third error occurs when parents claim a child who does not meet the IRS definition of a may have access to child. The child must be under 17 at the end of the tax year, be a U.S. citizen, national, or resident alien, and have a valid Social Security number. If the child turns 17 on December 31, they do not may have access to for that year. These details affect both the non-refundable and refundable portions.

What happens if you receive an incorrect refund amount

If the IRS determines you claimed a refundable credit you were not may have access to to, they will send you a notice and ask you to repay the excess. This can happen if your earned income was lower than you reported, if a child did not meet the may have access to requirements, or if you claimed the same child on multiple returns.

You have the right to respond to the notice and provide documentation if you believe the IRS made an error. Keep records of your children's birth certificates, Social Security cards, and proof of your earned income (W-2s, 1099s, or business records) for at least three years after you file.

If you cannot pay back an overpayment when ready, the IRS can explore it to future tax bills or set up a payment plan. You can also request an installment agreement if the amount is substantial.

Frequently Asked Questions

Can I get the refundable credit if I have no tax liability?

Yes, if you have earned income above $2,500 and claim may have access to children. The refundable portion exists specifically to send money to families who owe little or no tax. You must file a return to claim it, even if you would not otherwise be required to file.

What counts as earned income for the refundable credit?

Wages, salaries, and net self-employment income count. Social Security, unemployment, pensions, interest, dividends, and rental income do not. If you are self-employed, use your net income after the self-employment tax deduction, not your gross receipts.

Is the refundable credit the same amount for every child?

The maximum refundable amount is $1,700 per child, but the actual amount you receive depends on your earned income. The credit phases in at 15 percent of earned income above $2,500, so a family with $3,500 earned income and two children would receive less than the full $3,400 maximum.

What if my child was born in December?

Your child must be under 17 at the end of the tax year to may have access to. A child born on December 31 is still under 17 on that date, so they may have access to for that year. A child who turns 17 on December 31 does not may have access to because they are 17 at year-end.

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

No. You must file your own return as an independent to claim any Child Tax Credit, refundable or not. If someone else claims you as a dependent, you cannot claim the credit for your own children.
