I am currently working as U.S. DoD contractor in Afghanistan. I arrive in Afghanistan late October 2010. I will be over here until at least October 2011. I know that when working overseas for 330 days or more, the first about 90 thousand dollars are tax-free.
What I don't know is how to fill my tax for the 2010 year. At the end of the year, I wouldn't have been over here for more than 330 days. So I wont get the tax break. At least that is how I understand it. Is this correct? If so, will I receive my take break for the 2011 year if I am not overseas for more than 330 days of 2011? Even if I have served overseas 330 days of the last 365 days?
