Your children are above the age limit to be considered a qualifying child (your child must be under age 19 or, if a full-time student, under age 24. There's no age limit if your child is permanently and totally disabled.)
However, they may be a qualifying dependent. Here's the qualification test from Rules for Claiming Dependents on Taxes :
- Do they live with you? Your relative must live with you all year as a member of your household or be on the list of “relatives who do not live with you” in Publication 501. About 30 types of relatives are on this list.
- Do they make less than $5,050 in 2024 ($5,200 for 2025)? Your relative can't have a gross income of more than $5,050 in 2024 and be claimed by you as a dependent. This threshold increases to $5,200 for 2025. Certain income is excluded from this requirement such as all or part of Social Security benefits.
- Do you financially support them? You must provide more than half of your relative's total support for the year.
If you believe they qualify as a dependent, you can add them here:
