Frequently asked questions

Tax year 2024/filing season 2025 Child Tax Credit frequently asked questions.

Can a child be a qualifying child of more than one person?

Relationship Test

To meet this test, a child must be:

  • Your son, daughter, stepchild, or foster child, or a descendant (for example, your grandchild) of any of them; or

  • Your brother, sister, half brother, half sister, stepbrother, or stepsister, or a descendant (for example, your niece or nephew) of any of them.

 

Adopted child.

 

An adopted child is always treated as your own child. The term “adopted child” includes a child who was lawfully placed with you for legal adoption.

Foster child.

 

A foster child is an individual who is placed with you by an authorized placement agency or by judgment, decree, or other order of any court of competent jurisdiction.

 

 Age Test

To meet this test, a child must be:

  • Under age 19 at the end of the year and younger than you (or your spouse if filing jointly);

  • A student under age 24 at the end of the year and younger than you (or your spouse if filing jointly); or

  • Permanently and totally disabled at any time during the year, regardless of age.

 

Example.

 

Your child turned 19 on December 10. Unless this child was permanently and totally disabled or a student, this child doesn't meet the age test because, at the end of the year, this child wasn't under age 19.

Child must be younger than you or your spouse.

 

To be your qualifying child, a child who isn't permanently and totally disabled must be younger than you. However, if you are married filing jointly, the child must be younger than you or your spouse but doesn't have to be younger than both of you.

Example 1—child not younger than you or your spouse.

 

Your 23-year-old sibling, who is a student and unmarried, lives with you and your spouse, who provide more than half of your sibling’s support. Your sibling isn't disabled. Both you and your spouse are 21 years old, and you file a joint return. Your sibling isn't your qualifying child because your sibling isn't younger than you or your spouse.
