ITC claimed under incorrect head and annual return filed

This discussion addresses a common GST issue where Input Tax Credit (ITC) was claimed under the wrong head (e.g., IGST instead of CGST/SGST) and the annual return has already been filed. The recommended solution is to file Form DRC-03 to correct the error and set off the wrongly claimed ITC using either cash or credit ledger. It's important to note that GSTR-3B and GSTR-9 cannot be amended, making DRC-03 the primary method for rectification.
