<prompt> Human: So I lived with my parents for just a little over half of the year. I have been working full time since May I am under the age of 24 but over 19 I am NOT in school whatsoever. My parents first tried to claim me as a dependent on their tax returns but it was rejected, but now they are trying to file my 2 year old son. I plan on filing my own taxes I made it a little over 11,000 dollars this year all of my paychecks went directly to them to pay for my living expenses . Can they legally file my son as a dependent , even though I was providing all the support for him just living in their house? Also I was providing day care support for my son for almost half the year.Update: thanks everyone for all the info and support. I decided to contact a certified accountant today. He informed me to file mine claiming him as soon as possible just waiting on my w2 He informed me that the irs will likely award me because Im the biological mother and care giver. The IRS will require one of two things from them 1. A signed form from me allowing them to claim him or 2. Financial documented proof that they supported him. Both of these they dont have. He believes the irs will award it to me. Again thanks reddit for being so helpful.2nd update: after some long discussions with my parents today by text. I stopped by their house. My dad informed me that he pulled back his return and its removing my little one. He informed me to go ahead and file with him on mine. Thanks again reddit!  <response>: They clearly are thinking of themselves and not you or their grandchild, according to the story. File your taxes correctly and let them know you are doing so. I suspect, their argument is that they basically raised your son last year.As long as you do the right thing, you wont be penalized...by the IRS at least.
