So i just started my first job...and as I understood, the lower the number you put, the least they take out in taxes. So I put a "1". Throughout college I would put "exempt", but I figure now that I am out, I need to put something there. Well anyways I got my check today and they took out 27% total for taxes

Is this normal? Or should I refile...single and no one will claim me as a dependent.
