Defective return

I had filed return of AY 2012-13 0n dt.5/08/2013 with following details:

Business Loss - 46,000

Income from other source - 251000

Total income  - 5000

And paid tax on the above amount on the same date.

Later i have received a notice u/s - 139(9) i.e defective return in which it was mentioned that the Assessee entering negative amount in gross profit or net profit.

My is question is that whether i claim the business loss by filling return after the due date i.e. 31.07.2012.

Please advise
