Revised Return after Refund is Received ?

This discussion explores whether a revised tax return can be filed after an initial return has been processed and a refund has already been received. While some advice suggests it's not possible once processed, others indicate it might be permissible under Section 139(5) of the Income Tax Act, particularly if the 'assessment' refers to a specific type (not just an intimation under 143(1)). The consensus leans towards it being possible to claim an additional refund, but clarification on the exact process and potential limitations is sought.
