Reply #123: you know that almost no one actually double pays, right?

here's how the game works. you get a roughly $95k exemption. you then deduct all the taxes you pay on any amount above that to the country of residence. The reason people give up their US citizenship to avoid taxes is to avoid the rules about foreign income. the UK Inland REvenue doesn't tax money made outside the UK for UK residents. the US taxes global income (minus, of course, any taxes paid in the country it is earned in.)
