For AY 2011-2012, total income was (salary+interest) below 5lakhs. So the assessee didnt file return.(Notification 9/2012) Subsequently certain amount of income had to be added & further tax was needed to be paid in February 2012. The question is WHETHER INTEREST U/S 234A IS NEEDED TO BE ADDED, COZ THE RETURN FILING IS NOT MANDATORY DUE TO THAT NOTIFICATION...!
