Why does the child tax credit not actually lower what you owe?

[DianeW777]

The child tax credit (CTC) will first reduce your tax liability, then then depending on your situation the additional child tax credit (ACTC) may be a refundable portion shown as a payment on Line 28, Form 1040.  Review the information and your tax return to see how the credit is applied based on your income. You must have at least $2,500 in earned income for the ACTC to apply.

Not sure what line you are looking at that makes you think the CTC does not lower your tax liability.  

Make sure you have entered your child as a dependent in My Info, and that you have entered the child's Social Security number.    Careful— do not say that your child’s SSN is not valid for employment.  If your child was born in 2025 make sure you said he lived with you the whole year.  There is an oddly worded question that asks if the child paid over half their own support.  Say NO to that question.

If your dependent was a full-time college student, make sure you were careful on the MY INFO screen for “Uncommon situations” and that you indicated there that they were a student.

Have you entered income from working in 2025?  If not,  you will not receive an income tax refund based on having dependent children.

  The maximum amount of the child tax credit is now $2200 per child; the refundable “additional child tax credit” amount is $1700.   In order to get that credit, you have to have income from working.  

Take the amount you earned from working.   Subtract $2500.   Multiply the rest by 15%.  That is the additional child tax credit per child that you canget—- up to the maximum of $1700 per child.   If the amount you earned from working was low, you will not get the full $1700 per child.

 If your child is older than 16 at the end of 2025, you do not get the CTC.  But you may still get the non-refundable $500 credit for other dependents instead.
