I've been sent the details of a package for a job in America and all of the costings are listed before tax. I've tried looking up how much I will actually get after tax but am getting confused between income and federal tax and whether my flight allowance and shipping allowance would be taxed too and if so by how much. Can anyone help clear my confusion up? Also how easy is it to set up a us bank account as I guess this would have to be what I do...do I wait till I'm over there to do it? Thanks!
