One of our client who is individual, of whom we have filed IT return for the F.Y
2011-12 within due date.
But just now I have found that during that year he had received gift on his
marriage of an amount around Rs. 10 lakhs which is exempt from tax, but while
filing return we have not taken count of that income.
So, my query is that do we required to file revised return or no revised return as
there would not be any change in tax liability?
