Which visa do you have? Are you resident of the U.S.?
When did you enter the U.S.?
Did you file 2008 tax return in the U.S.?
The purpose of asking this info is that may be the income earned on project away from U.S. is not taxable in the U.S.
Also if this is the first time you will be filing tax return in the U.S., then you need not worry about advanced payment. Pay all tax due before April 15, 2010.
I have L1 visa,I am a resident of USA.. i have work authorization.I entered US on 12 jan and left in a week as i had to finish my project in india for three months and i came back and joined office in US on 12 april.During this time i had no SSN but i was paid in cash in US dollors and no taxes wre shown or given.I did not file any taxes for 2008 as i joined my job here for the firsttime in Jan 2009.
My worry is can in any way i can file taxes for my first quarter jan-feb-mar...now..if yes how....
