No tax for nonresident when working outside US?
TO:
Tax experts or tax experienced
I arrived in the US on 09/14/2007. I have been outside the US for work (business trips) after 09/14/2007 and I have been outside the US for vacation. My first 31-day period starts 11/27/2007 (when I become a resident alien).
I want to apply for the first-year Dual-Status. I don not meet the SPT in 2007, but I will have my 183 days in 2008 and will file for an extension.
Question:
All my days outside the US I did when having a nonresident alien status (between 09/14/2007 and 11/27/2007).
a. Is my income I earned from the US employer taxable for the days I worked outside the US? If not, where can I find literature about this topic?
b. how about the vacation days I spent abroad?
Thank you!
