<prompt> Human: Hi there. Im trying to figure out how much i can make per month with a part time job, and i am having a hard time figuring out just what percent part time work is taxed. I live in Florida, so i at least know there is no state income tax. Ive been told its about 20 with social security tax and a few others. Any help you could give me is appreciated. Thanks!  <response>: As far as taxation goes, part time vs full time makes no difference. If you already have a job, and you want to get an additional part time job, you are taxed at your highest incremental tax bracket. So if your FT job puts you into 15 bracket, all your PT income will be taxed at 15 plus SS and FICA until you get to the 25 bracket threshold. If you dont have any other income, you only pay SSFICA on your first 10K if nobody can claim you as a dependent.
