Okay my husband owes student loans that he made before we got married. We filed together last year and they took all my money along with his. I would like to file separately this year so I can get the child tax credit for our 8 month old son. I did work in 2017 but it's saying I have no refund for this year. Also I read that if I'm married filing separately, I probably wouldn't be able to do the child tax credit. Why? We moved to Tennessee from Texas October 31st of 2017. Would that be some of the reason? Please help.
