Can I claim as a dependent my mother-in-law who lived with us until November, when she passed. We supported her and paid her bills.

[SharonD007]

It depends.  You may be able to claim your mother-in-law as a qualifying relative (even if she didn’t live with you) as long as she meets the requirements below.

• Must be a U.S. citizen or resident, or a resident of Canada or Mexico for part of the year
• Made less than $4,700 gross income (except nontaxable Social Security benefits) in 2023
• Received more than 50% of their support from you 
• Must not be claimed as a dependent by another taxpayer
• Must not file a joint return
