This discussion addresses issues with GSTR-2B generation for February 2024, leading to the incorrect claiming of Input Tax Credit (ITC) and Reverse Charge Mechanism (RCM) in GSTR-3B. Participants clarify that claiming ITC without it appearing in GSTR-2B is a wrong claim and requires reversal with interest. The consensus is that if ITC was claimed in February's GSTR-3B but only appeared in March's auto-population, it must be reversed in March with 18% annual interest, which can be paid in the following month.
