Hi there,
   Well an advice that cud work out for ya would be to file for self-employment. Go to a CPA (if Nep/Deshi would be much better).. and tell him ya wanna e-file for the year 2010 for self-employment. 
    Note: Ya have to file a Form 1040(with Schedule SE attached). The self-employment tax rate is 15.3% out of which 12.4% is Social Security and 2.9% is Medi-care.. but if ya r a student, ya do not have to pay for social security and medicare.. ya know wut.. ur CPA wud guide ya thru all this.. instead of extending till October 15 and paying interest & penalties, dude I wud do this asap. The due date is April 15 only in case the 15th falls on Saturday/Sunday or legal holiday, the due date is delayed till next business day... Just make sure..when ya e-file ur taxes.. ur Total Income stays above the poverty line of ur state..where ya reside..
              Gud luck..
