Can I claim my grandmother on my taxes even though she passed away in January?

[Vanessa A]

Possibly.  If she would otherwise qualify as a dependent on your return, then if she died in 2023, then you would treat her as living with you for the entire year.  

To claim someone as a Qualifying Relative, they must be:

• Your child ( including step children, adoptive children and foster children) or a descendent of them
• Your sibling (including half siblings) or a child of your sibling or a sibling-in-law
• Your parent or grandparents, including step parents and in laws
• Any other person that lived with you for the entire tax year
• Not a qualifying child of another taxpayer
• Someone that you provided over half of their support for during the tax year
• Has less than $4,700 in income (not counting social security)
