Return u/s 139 (9)

There is never any enough reason to igore any notices from Itax deptt. If it was filed online, login again and you will have to first collate data according to said deduction and then upload. if notice is expired, call CPC and get a fresh notice and the apply.

@ Harsh Gupta: The due date to file returns of partnership firm who are not under tax audit for FY 2012-13 was extended to 05.08.2013 which was otherwise 31.07.2013. And for those under audit was extended to 31.10.2013 which was otherwise 30.09.2013. Now looking at the information that you have provided it seems that the firm was not under tax audit otherwise it was well within the due date. The original return that was filed was a belated return and hence such return could not be revised. Hence you must have got notice u/s 139(9). The notice u/s 139(9) must be answered within 15 days else it would be presumed that no return was filed for that year. However, you can convince the AO to reconsider your case and ask for a fresh notice and then file the return as per the notice
