Hi,
I understand there is time limit within which a person can file a revised return quoting the ack/no etc of the original filing.
But nowadays the processing seems to be happening very quickly (for eg. a return filed in July 2016 before-due-date) was processed and refund credited by Jan-2017.
How can a revised return be filed (and under what section) in such a case (that is original processed and refund-credited)
thanks
