fraud from who, yeah people claiming kids that's not theirs is fraud, but guess what, I been taking care of my step son since he was one, he is 10 now, and no I'm not getting married just another loop hole for the government to trap you, did it once we went to college and every time somebody got behind on payments everybody tax return was garnished, having to file injured spouse and wait weeks and months., whatever life happens and that degree I'm paying for got me nowhere...anyway I filed for my stepson for the first time last year because his mom wasn't working and BOOM I got audited, and was told it was illegal, even though they sent me a checklist of things to send in as proof, I sent everything they asked and I still got denied, So I called and flipped out like ok, you guys aren't looking for his dad, the man owes all this child support, I'm with the mother I step up to the plate I take care of him, he calls me Daddy and because were not married, I cant claim him? So when I walk in the store to buy him clothes food anything, do I have to provide a marriage certificate before I can legally buy him anything, when I was paying child care costs, did I need a marriage certificate? better yet when I tried to put his mom and him this year on my return as people in the household, who I support, not even for earned income credit, he is a child and she don't work, it deducted $1000 and some change off my return, but when I took them off and it was just me and my biological son, it went back up $1000, it was like the government was saying "SHHHHH...just keep your mouth shut about them 2 and take this extra grand"
