It return

Dear Sir,

Return once filed cannot be cancelled.

You have to revise the return for the year 2011-12.

You have got 120 days to send the acknowledgement to Bangalore CPC. If they have not received within 120 days, then the Department will treat the return as invalid.

You should file the return for 2010-11 subject to penat provisions. And then revise your 2011-12 return. 

Sir i would like to add 

AY 2011-12 --  return filled if correct than printout ITR V and send it to CPC,, if not correct than don’t send ITR V and filled revised return, even if you don’t send ITR V which is considered to be invalid return , during online filling system will required to file revised return and as regards to then manual filling I think return would not be revised  return but original return.

AY 2012-13 – return of AY 2011-12 filled so don’t send ITR V and for  correct return of AY 2012-13 revised return to be filled
