Alot of people are single parents that fight over the child tax credit every year. While both parents have their own homes and own expenses. If you have a child and are not married or are a single parent you should be able to claim your child on your taxes.
Usually 1 parent holds that over the other parents head claiming they deserve to claim the kid(s).
Its hard enough being a single parent let alone dealing with the financials all by yourself. That tax credit would be huge for so many people especislly single dads or moms who need the help. In turn that would boost economy off of more money in parents pockets.
