I believe the way the tax thing works is if you are working for an American company, you would have to pay tax on what you make over like 82,500. I can't remember the exact figure, but I think that is close. If you are working for a Qatari company, or Middle Eastern company, then your income is tax free. You need to consult with a tax attorney before you come over though, just to cover yourself. For a single person, that salary is more than adequate. Hope that helps. :)
