During the month of January-2025, some dealer generated a bill in our Company name and uploaded it in their GSTR-1. We didn't purchased the items and not received the bill. We didn't claim the Input Credit of Rs.7200/- despite it is shown in GSTR-2B. Now during the month of April-2025, they reversed bill which is reflecting in our GSTR-2B. Our actual IGST credit for the month of April-2025 is Rs. 65700/-. But in our GSTR-3B the IGST credit available is Rs. 58500/- ( 65700-7200). Now what is procedure to reconcile this in my books and GSTR-3B. Regards
