My son is to old to claim as a dependent can i claim him as a qualifying relative dependent ?

Maybe----but you have  not provided us with any information about your son.

 

Qualifying relative

• They don't have to be related to you (despite the name).
• They aren't claimed as a dependent by someone else.
• They're a U.S. citizen, resident alien, national, or a Canadian or Mexican resident.
• They aren’t filing a joint return with their spouse.
• They lived with you the entire year (exceptions apply).
• They made less than $4,400 in 2022.
• You provided more than half of their financial support.

 

If you can claim him as a qualified relative you get the $500 credit for other dependents.

I have a similar question and would really appreciate some help... My son meets the income test to be a Qualifying Relative. He is a full time grad student and took out Federal Un-Sub Loans in 2023. Do these loans count as support he provided for himself? If so, it appears I can't claim him. If not, it looks like I can claim him as a Qualifying Relative and this really helps our refund both on taxes, and Health Insurance APTC. I'd really appreciate some help on this one because it is very confusing to me when I try to determine this, Thanks!!

Borrowed amounts used to support the older child is considered support by that child. 

 

IRS Publication 501 Dependents, Standard Deduction, and Filing Information, page 19 states:

 

      Tax-exempt income

 

      In figuring a person's total support, include tax-exempt income, savings, and borrowed amounts used to support that person. 

 

      Example 2. 

 

      K, your sibling’s child, takes out a student loan of $2,500 and uses it to pay college tuition. K is personally responsible for the loan. You provide $2,000 toward K’s total support. You      can't claim K as a dependent because you provide less than half of K’s support. 

 

Another issue to consider, also on page 19.

 

      Person's own funds not used for support

 

      A person's own funds aren't support unless they are actually spent for support.

 

Imagine this scenario.

 

In the example above, if the child borrowed $10,000 in 2023 and saved back $7,500 for use in 2024, the $2,500 spent in 2023 is considered the amount of support by the child in 2023.
