<prompt> Human: I worked for about 5 months this year. My first job ever. I am twenty, recently on a break from school. I live with my mom and 2 younger sisters. Mother is undocumented, and shes been toldby other people on a similar situation that I should put my sisters as dependents when I file my taxes. Is this illegal?  <response>: Thats tax fraud unless you provide more than half of their support. Being that youre 20 and didnt work half the year, Im assuming you didnt make that much money. Claiming 2 dependents on virtually no income is massive audit bait for the IRS, and you almost certainly, in your situation cant get more back than what you paid in anyway, which you probably already will get or very close to it. You really dont need the IRS coming around the house.Source: am accountant
