@ Dhirajlal sir... But wouldn't the assessee also have to pay back the amount initially received as refund?
The thing is.. I had dealt with a similiar case (involving IT investigation) myself, where I had to manually add the refund amount to the revised tax computation and pay the total amount as SAT.
I will try to illustrate my point as follows:
In above image, suppose we have already received Rs.400 as refund in our bank account. Subsequently, we notice an error in RoI and hence we draw up the revised return and the net liability turns out to be Rs. 300. Now if we were to pay only Rs. 300 as SAT without returning the initial refund, then wouldnt the department ultimately be at a loss of Rs. 100 (ie., Rs. 400 - Rs. 300). Another way to view this could be that TDS in 26AS has already been refunded initially. Claiming it again in the Revised Return, may result in Double Benefit.
The question is (in above example) shouldnt the assessee be paying Rs. 700 + Interest?(ie., Rs. 300 --SAT + Rs.400 --Refund wrongly recd).
Also if yes, then returning to Ms.Shivani's Qn.. how to treat this in the Revised ITR?
