<prompt> Human: My mom and dad are divorced and remarried, and my dad has primary custody so him and my stepmom are ones Im putting information on for FASFA from what I understand. I have six younger siblings on my dads side 2 step siblings, and four on my moms side. My mom puts down my two youngest blood siblings down as her dependents, even though she doesnt pay 25ths of their expenses to cost them as dependents, or pay for child support for any of us at all like shes supposed to. She can almost certainly contribute way more to my education than my dad and stepmom, but Im trying to figure out if it would be worth it to convince her to start filing her taxes correctlyat least actually provide for the two dependents, or just drop it and avoid a big fight. Apparently she gets money back when she files her taxes, but thats definitely going to change next year as my stepdad makes a lot of money. edit: Mom has joint custody, me and my siblings spend more time at dads.  <response>: Your mothers income will literally have no bearing on your FAFSA as long as you use your dad and step-mother as your listed parents on your FAFSA. Since you live with your dad, you have to use him. Also, if he knows for a fact that he supports your siblings more than 50 financially speaking and honestly, this can be interpreted in a few ways, then it doesnt matter who claims who on taxes. Claiming people on the FAFSA is different than claiming people for your taxes.Source: Am Financial Aid Counselor for a college.
