I am a Canadian Citizen who owns my own business (registered as a Sole Proprietorship) and I do contract work and consulting for US clients sometimes. I am living outside the US as well so thankfully I don't have US tax, the biggest difference for me is that I don't need to charge US clients sales tax where I live, but for local clients I do need to collect an additional tax and pass that on to the government.
