From the July 2025 tax period onwards, Table 3.2 of GSTR-3B for inter-State supplies will be auto-populated and non-editable, requiring taxpayers to file returns using system-generated values. Any corrections to these values must be made through GSTR-1A or Form GSTR-1/IFF before filing GSTR-3B, ensuring accurate reporting in GSTR-1, GSTR-1A, or IFF is crucial.
