To ensure your authorized signatory and mobile number are registered on the GST portal, you need to log in to your account on the portal and update the relevant details under the 'Registration' section. The authorized signatory must be a valid person listed on your GST registration, and the mobile number should be associated with that person.
To file a NIL Form CMP-08 via SMS, you need to send an SMS to 14409 in the following format: "NIL (space) C8 (space) YOUR_GSTIN (space) RETURN_PERIOD".
