I was a full time partner of a firm whose accounts required audit u/s 44AB for the A.Y. 2013-14. Due date for filing income tax return was 30/09/2013 and i had filed income tax return on 30/09/2013 in which i had claimed carry forward of Short term capital loss.
I received intimation u/s 143(1) in which due date for filing income tax return was mentioned as 31/07/2013 and hence claim for short term capital loss was disallowed. Later I discovered that i had mentioned incorrect pan number of the firm. I have received income tax refund for the a.y. 2013-14.
My question is what do i need to do so that short term capital loss will be allowed to carry forward? Whether shall i file revised return as i have discoverd an error or shall i apply for rectification? Only claim for carry forward is going to change and there will not be any further demand or refund?
