For those who don’t know, the US has a tax stimulus program for 2008 which can result in significant refunds from the US tax authorities. As for taxpayers living abroad, some of you will get the rebate, some won’t (including some who pay significant taxes in the US). Check out this post from taxgirl to find out which category you’re in.

It’s coming on that time, so those of you who do (or may) have to file your taxes in the US can check out the IRS page on international taxpayers to try and understand your filing obligations.
If you’re doing this for the first time, check out Classification of Taxpayers for US Tax Purposes to find out where you fit, then look at the relevant publication below. If I were doing it, I’d read Alien Taxation – Certain Essential Concepts first, for an overview of the system and US taxation abroad.
Best of luck on that …
