Some info about my situation:
I turned 24 in 2018. I graduated from school in May 2018 and got married the same month. While in school I lived in a dorm and paid my own expenses with a part time job, and since graduating my husband and I have lived at my mother’s house. She paid all house expenses except for gas and electric which we split with my brother. The rest of our expenses we paid ourselves. I worked on and off for the rest of the year and in total made about $5300.
Now my question: can my mother claim me as a dependent? We would like to file jointly in order to get the benefits of being newly married but she claims that she can claim me since I was in school 5 months of the year. She also says that not claiming me would mean having to pay a lot back to the IRS since she said she would claim me on her w4 at the beginning of the year.
Is she allowed to claim me?
Several items involved here:
Here is an interesting link that might help you ... it is an interactive interview at the IRS site to walk through questions regarding dependency: https://www.irs.gov/help/ita/whom-may-i-claim-as-a-dependent
Not sure what your relationship is with your mother (assume it is OK since you are living at her house), but if your mother can claim you as a dependent doesn't mean she has to. I would suggest looking at your taxes using different allowable scenarios and see if in fact your mother would be losing big on not claiming you and figure out a middle ground to minimize your taxes in total. Put another way (example only), her saving $2000 on taxes doesn't make a lot of sense if you are paying $5000 more and vice-versa.
It is much simpler than this - Qualifying child failed because of the Age Test (younger than 24), Qualifying Relative failed because of the income test (less than $4,150). Since you have to meet all the test to be a dependent you are not. Filing jointly, full time student, support, and exemption does not matter.
@ZTaxPro is correct; age is under 25 for dependency. Thanks for catching my brain cramp (of 25 and under).
