Missing the ASMT-11 reply window does not end the matter. The proper officer can grant an extension of up to 15 additional days on receiving a written adjournment request , file one immediately citing the factual reason for delay.
If the extension is denied, the officer cannot raise a demand directly. They must first issue a Show Cause Notice under Section 73 or Section 74 of the CGST Act, and you get a full opportunity at that stage to submit your reply and supporting documents.
Key steps to take now: (1) Contact the jurisdictional GSTIN officer in writing requesting an extension, (2) Prepare the ASMT-11 reply explaining each discrepancy raised in the ASMT-10, and (3) Gather reconciliation between GSTR-3B and GSTR-2A/2B to support your reply.
