I have a question about my federal tax withholding. I got 500 some dollars from federal and they only took out 179.60. As for my state returns I got around 200 and they only took out 110.13. I started on twilight and they took out 643.70 for federal and 200.91. I used the federal calculator and it said i'm only getting back 643 why is it so low? I have 0 dependents. Also is United Way a tax right off?
