My son decided to move into an apartment with his girlfriend in 2020. They moved in the first week of July (6 months in my house), and then they both moved back into my house in July of 2021. Both are college students. He makes a very small income through a campus job. She has an income through a full-time (almost) job. I have always paid all college expenses, and claim him as a dependent. I have no idea about her tax status between her and her parents. How does this affect my taxes? He has never filed due to his not earning very much. Have I made mistakes?
