My son filed his taxes already. He marked "no one can claim me as a depndnt,but I support him.If he does need to amend will that effect the amount he was getting back ?

[missimaui]

He is a student was working part time but I have been paying for all his needs,rent,food,electricity,clothing. He is no longer employed as he quit his job. I am entitled to claim him but don't know what to do now that he already filed and stated that no one else could claim him as a dependent. I also need to know if it will negatively impact his return if he does do an amendment and I claim him ?

He may have received stimulus money based on saying that he cannot be claimed and would need to re-pay it.  Was he a full-time student in 2020?  You have not mentioned his age or how much income he had in 2020 before he lost his job---and those things are important in determining if you can claim him.

WHO CAN I CLAIM AS A DEPENDENT?

You can claim a child, relative, friend, fiance (etc.) as a dependent on your 2019 taxes as long as they meet the following requirements:

•They are related to you.

•They cannot be claimed as a dependent by someone else.

•They are a U.S. citizen, resident alien, national, or a Canadian or   Mexican resident.

•They are not filing a joint return with their spouse.

•They are under the age of 19 (or 24 for full-time students).

• No age limit for permanently and totally disabled children

  •      They live with you for more than half the year (exceptions apply).

When you add someone as a dependent, we'll ask a series of questions to make sure you can claim them.

He is 20 a full time student and earned more than 4,500.00. He didn’t get a stimulus throughout the year but did get the credit on his tax return: Even though he is supported by me I decided I would file and not claim him .

When big bucks (EIP) are involved, you have to think long and hard about how you file. Or maybe not.

If you don't claim him, you are giving up the potential tuition and AOC credits for a college student.

[missimaui]

Well he actually paid his tuition himself. If I was to claim him he would have to payback the stimulus money he got. When I added him as a dependent to see how much more I would get back it was around $1,600.00 more that i would get back . He would have to pay back the $1,200.00 stimulus he got, and I don’t know how much more he would have to pay back.

Actually, if you are entitled to claim him, he can't claim to be independent. Even if you did choose to not claim him, he is not entitled to the stimulus.

[missimaui]

Well we did some research and he is one credit short of what they consider a full time student or one class but he doesn’t qualify as a full time student and he made more than $5,000 last year so I am not actually entitled to claim him .
