The GSTN has issued an Advisory dated 20.11.2025, regarding Mandatory Furnishing of Bank Account Details under Rule 10A. The advisory applies to all registered taxpayers except those registered under TDS, TCS, or suo motu registrations.

Rule 10A mandates that every eligible registered taxpayer must furnish their bank account details either Within 30 days from the date of grant of registration, or Before filing GSTR-1 or IFF, whichever is earlier.

GSTN has announced that system-level enforcement of Rule 10A will be implemented shortly on the GST Portal. Once implemented, taxpayers who have not yet uploaded their bank account details may face automatic suspension of GST registration, resulting in disruption of business operations.

The advisory also explains the procedure for furnishing bank account details via non-core amendment by navigating through:

Services → Registration → Amendment of Registration (Non-Core Fields).
