Claiming Adult Dependent

Yes.  The support she provides does not have to come from earned income.    If she meets the qualifications to claim him, she would be entitled to receive the stimulus money also, even if he already received it.   No, neither of them will have to pay it back if she can claim him and does so.    And yes, if she provides over 50% of his total support, and meet the other requirements, she should claim him.   But he should not file a tax return and claim himself; a person can only be claimed as a dependent on one tax return each year.   

Here are the qualifications.

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 $4,300 in 2021.
• You provided more than half of their financial support.   Click this link for more details.   

To determine this, compare how much you spend on this person's necessities with how much they (or somebody else) contributes.

• Divide per-household costs like utilities, groceries, and lodging by the number of household members to determine the per-person cost.
• If your mortgage is paid off, use the fair rental value of your home to figure the lodging expense.

If you are paying more than 50% of another person's necessary living expenses, you financially support that person.

Sorry just have 1 more question to ask. Our uncle is not disabled. She can still claim him even though he doesn't have a disability, right? I thought i read online somewhere that you could only claim adult dependents if they were disabled, or in college.  He's just been down on his luck so she took him in to try and help him get back on his feet.
