Being that we're in the midst still of tax season here in the States, a question suddenly ocurred to me and it's actually pretty scary that I didn't think of this before, but, let's say that (hypothetically speaking as far as the DATES go) I were to move to Brazil in October or November of this year (2013). How then do I file for my 2013 U.S. taxes once I'm THERE if I don't want to have to fly back to the States just for that? IS there a way of filing without coming back to the states?
