F-1 on OPT, non-resident, going back before tax filing 2007
I came to DC in summer of '05,
graduated in Dec. of '06, and have been working since Jan. 07 on OPT, F-1 status.
However, I am going to go back to South Korea in Oct. of '07 before my OPT runs out.
To sum up, I have been in DC for about 2 years now and I'm a non-resident alien for tax filing purposes- hence, I only had to hand in Form 8843 for 2006 tax period in May (?) of this year.
However, since I have been earning wages from my employer since Jan. of '07, I realize I have to pay taxes. My employer has not been witholding any portion of my wages, but I have no idea how much I am supposed to be putting aside for taxes, no less, how to actually go about filing these taxes.
I am not sure if there is a way I could get this done before I leave in October, and what forms I would have to fill. I have a dreaded feeling that I may have to wait till the tax filing period come March-April '08, but I want to get this over and done with before I leave!
Any advice/help would be much appreciated!
