One of my supplier has filed GSTR-1 for the month of May, 2021 & i have duly availed ITC against his invoices as they were showing in my GSTR 2A in the month of may. But he has not filed GSTR 3B for month of May, 2021 & hence not paid GST for the month of May, 2021 and is absconding now. Amount equivilant to GST Input is still payable by me. I want to reverse the ITC claimed in month of May, 21 & reverse the same in my August 3B. How & where to reverse in GSTR 3B & under which section.
