Rule 88C, CGST Rules 2017; Rule 59(6), CGST Rules 2017
Since GSTR-3B liability is now auto-filled and locked from GSTR-1, new gaps mostly come from older periods or GSTR-1A changes. Typical genuine reasons are invoices reported in GSTR-1 of one month but taxed in GSTR-3B of another, or advances already taxed. Explain with amounts, or pay through DRC-03 with interest where tax was short.
