Form ASMT-10 is a scrutiny notice issued by a proper officer under Section 61 read with Rule 99 of the CGST Act, 2017. It is issued when the tax authorities identify discrepancies between the data available with the department — such as data from GSTR-2A, GSTR-2B, GSTR-3B, e-Way Bill portal, or data received from third parties — and the returns filed by the taxpayer. The notice points to specific line-item discrepancies and asks the taxpayer to provide clarification or to accept the discrepancy and pay the differential tax.
An ASMT-10 is not a demand notice — it is an opportunity to explain. If you provide a satisfactory explanation, the officer is required under Section 61(2) to drop the scrutiny proceedings by issuing Form ASMT-12. If the explanation is unsatisfactory or no reply is filed, the officer can proceed to initiate Best Judgment Assessment under Section 62 (Form ASMT-14) or a formal demand under Sections 73 or 74. Acting promptly and precisely within the 30-day window is therefore critical.
In practice, this means that even for discrepancies below the ₹5 lakh threshold, filing the reconciliation table is strongly advisable as it demonstrates good-faith compliance and reduces the risk of the officer exercising discretion to escalate. Our ASMT-11 template below has been updated to include this reconciliation table in the prescribed format.
Use the following template as your ASMT-11 submission on the GST portal. Substitute all bracketed placeholders with your actual details. Attach supporting documents — reconciliation statements, ledgers, purchase registers, e-Way Bills, bank statements — as referenced in the template.

Dear Sir/Madam,
1. RECEIPT OF NOTICE
We are in receipt of Form ASMT-10 bearing the above reference number issued
under Rule 99 read with Section 61 of the CGST Act, 2017, pointing out
discrepancies in our returns for the above-mentioned tax period(s). We submit
this reply within the prescribed time limit and request that the proceedings
be dropped on the basis of the clarifications and documentary evidence
furnished herein.
2. DETAILS OF THE DISCREPANCY AS PER NOTICE
[Set out the discrepancy(ies) as described in the ASMT-10 notice, point by
point. For example:]
Point A: Mismatch between outward supplies in GSTR-1 and GSTR-3B
As per notice: Difference of ₹[amount] for the period [month/year]
Point B: Excess ITC claimed in GSTR-3B over GSTR-2B
As per notice: Excess ITC of ₹[amount] for the period [month/year]
3. OUR RESPONSE AND CLARIFICATION
Point A — Outward Supply Mismatch:
[Provide the specific reason. For example: "The difference of ₹[X] arises on
account of [credit notes issued / amended invoices in subsequent period /
rounding differences / B2CS adjustments / export invoices mis-classified].
We have enclosed a detailed statement (Annexure A) reconciling our GSTR-1
Table [X] and GSTR-3B Table [X] figures with our books."]
Point B — ITC Mismatch:
[Provide the specific reason. For example: "The excess ITC of ₹[X] represents
ITC that was available as per our purchase records but had not yet been
reflected in GSTR-2B because the supplier filed GSTR-1 after the cut-off
date for GSTR-2B generation for that period. The ITC has since appeared in
GSTR-2B for [subsequent month] and is fully eligible. Reconciliation is
provided in Annexure B."]
