<prompt> Human: Ive been searching all over but having a hard time finding what I am looking for. My girlfriend and I just had our first child a month ago. I make the most roughly 50k, and she makes around 30k and we are trying to figure out the best way to go about taxesclaimingdeductions etc...Child is on my Healthcare and I am on the birth certificate as the father and she does have my last name despite her mother and I not being married had to fill out an affidavit and take a paternity test per the shitty state of IndianaIf there is any advice on this, or links to sites that will break it all down I appreciate it. We plan on getting married but not rushing that step. Thank you!  <response>: Child is on my Healthcare and I am on the birth certificate as the father and she does have my last name despite her mother and I not being married had to fill out an affidavit and take a paternity test per the shitty state of IndianaYou make it sound like thats a bad thing. Its not. In many states an unmarried woman can put whatever name she wants on the birth certificate, and once your name is on it then you can have a very difficult time getting it change and getting off the hook for child support.
