How do I find out the gross income from my son's w-2 summaries?

Your AGI is not on a W-2.   It is on line 11 of your tax return from last year--on Form 1040.

 

You have not mentioned how old your son is or whether he was a full-time student in 2024---both of those are important for us to know.

 

IRS interview to help determine who can be claimed:

You can claim a child, relative, friend, or fiancé (etc.) as a dependent on your 2024 taxes as long as they meet the following requirements:

Qualifying child

• They're related to you.
• 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're under the age of 19 (or 24 for full-time students).
• No age limit for permanently and totally disabled children.
• They lived with you for more than half the year (exceptions apply).
• They didn't provide more than half of their own support for the year.

• 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.

As per xmasbaby0, there are rules for claiming dependents. There are basically five tests to determine if your children can be claimed by you as a dependent on your tax return.

 

They are as follows:

1. They must be your child, adopted child or foster child, brother or sister or a descendant of one of these. (i.e. This requirement is met if they are her grandchildren.) 
2. They lived with you more than half of the year (these exceptions apply).
3. They are under the age of 19 (unless they are a full-time student. In that case it is age 24. They can be any age if totally and permanently disabled.
4. You provided more than half of their support
5. The child does not file a joint return with anyone else (unless to claim a refund of taxes paid or withheld).
