Dear Vijayaanand,

You cannot return file for A.Y 2010-11 because, 31st March was the last date for filing returns for AY

10-11(because due date for belated filing of return is one yr from the end of relevant assessment yr or before the completion of assessment whichever is earlier) 

One year you can file 2 PY returns

all the best

Regards,

RAJESH CHOUDHARY

Upto 2 assesement year only you can file the return. in your case 2009-10 your due date of filling return is 31-July-2010 and may file upto 31-Mar-2011 without penalty and after up to 31-mar-2012 also you can file but officer may levy of Rs. 5000 penalty. but beyond 31-Mar-2012 we can not file return.

You cannot file return for AY 2010-2011 now. the last date to which u can file was 31.03.2012.
