Can I claim my older brother? he is homeless but visits and stays with us from time to time. He is my older brother, born on January 26, 1987.

He just visits once in a while?  Did you pay for over half his support?  

IRS interview to help determine who can be claimed:

Probably not.

To determent if your brother can be claimed as ax dependent, you must answer yes to the following: 

• Do they live with you? Your relative must live at your residence all year 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 $4,400 in 2022? Your relative can't have a gross income of more than $4,400 in 2022 and be claimed by you as a dependent.
• Do you financially support them? You must provide more than half of your relative’s total support each year.

In all cases, to claim someone as a dependent on your tax return, you can't be claimed as a dependent on someone else’s return.
