AOII Angel is correct. U.S. citizens need to file for U.S. taxes regardless of where they live. The U.S. is one of the few countries that requires this (though I hear the U.K. is also considering this now). Tax treaty agreements take much of the bite out of taxes payable, but it's still a hassle to file for U.S. taxes in addition to the taxes of the foreign country in which one presently resides.
