Can i file revised audited it return for 30th sep,2012

Yes you can file revised return u/s. 139(5) as long you have filed the original return in time. the revised return needs to be filed before the expiry of 1 yr from the end of the asst yr or before completion of asment whichever is earlier. so you can file revised return for the ITR pertainin to A.Y. 2012-13 on or before 31.03.2014. but the earlier you do it, better it is. bcoz then it will genuinely look like it was a genuine mistake and the IT Dept might not consider it for scrutiny. usually the risk of getin a scrutiny notice is higher in case of revised returns
