<h1>GST registration requires bank account details within 30 days or before filing outward supplies; failure triggers automatic suspension.</h1> Rule 10A requires taxpayers (except those under collection/deduction schemes and suo moto registrations) to furnish bank account details within 30 days of registration or before filing outward supplies in GSTR 1 or IFF, failing which the portal will automatically suspend registration. Bank details can be added via Amendment of Registration (Non Core Fields). Once details are furnished, cancellation proceedings are automatically dropped; if not dropped immediately, taxpayers may use the Initiate Drop Proceedings option. OIDAR and NRTP taxpayers are exempt, except OIDAR taxpayers who appoint a representative in India.
