The Rule 10A, mandate taxpayers, excluding those registered under TCS, TDS, or suo moto registrations, to furnish their bank account details within 30 days of obtaining registration or before filing outward supplies in GSTR-1 or IFF, whichever is earlier. The advisory states that the GST portal will soon implement the changes, and taxpayers who have not yet submitted their bank account information, must do so promptly to prevent suspension of their GST registration and potential disruption of business operations. Bank account details can be updated via a non-core amendment on the GST portal.
