ITC Taken of FY 20-21

A supplier mistakenly filed GST 1 under RCM on your GST number, leading to an incorrect ITC claim in GSTR 3B. The department has issued a DRC-01 notice for excess ITC utilisation. The suggested solution involves obtaining a certificate from your supplier confirming their error and tax payment, along with a clear explanation to the tax officer. A satisfactory declaration should be sufficient to resolve the issue.
