How many exemptions can I take- And still receive a refund?

You can claim H.O.H., but if you are trying to get more money now than you should only claim your child and self. If you claim more and don't have those other dependents when you do your taxes than you may end up paying the government back. A lot of people don't understand that when they file. When you file you taxes make sure you have your daycare receipts. Good luck.
