<prompt> Human: Im going to be starting my first job out of college this summer, and Id like to get a better idea of my after-tax income so I can create a realistic budget. My before-tax annual income will be 38,000, in the Washington DC area. I think taxes will end up being around 25-35 of my gross income, but Im really not sure. Im single as well. Any thoughts?  <response>: The good stuff starts on page 43.
