Key Pointers –

• All Registered Taxpayers are required to furnish details of their bank account/s within 30 days of the grant of registration or before the due date of filing GSTR-1/IFF, whichever is earlier as 30 Days period is shortly going to expire. This is to avoid disruption in business activities and the subsequent suspension of GSTIN.
• Failure to furnish the bank account within the stipulated time would result in the suspension of Registration after 30 days. Intimation in FORM REG-31 will be issued to the Taxpayer and additionally the Taxpayer would be debarred from filing any further GSTR-1/IFF.
• The suspension will be automatically revoked If the taxpayer updates their bank account details in response to the intimation in FORM REG-31.
• If the bank account details are not updated even after 30 days of issuance of FORM REG-31, the registration after suspension may also be taken up for cancellation process by the Officer.
