How to · GST · Scrutiny

A GST ASMT-10 is an inquiry, not a demand. The officer has looked at your returns, found a discrepancy, and wants you to explain it. Handled well, it ends there. Ignored, it can grow into an audit, an inspection, or a show-cause notice and demand. This page explains what an ASMT-10 flags, how to reply in Form ASMT-11, the time limit, and what happens if you do not respond. Last verified October 2026.

The short answer
  • What it is: an ASMT-10 is a scrutiny notice under Section 61 read with Rule 99, asking you to explain discrepancies in your returns. It is an inquiry, not a demand.
  • How to reply: answer in Form ASMT-11, explaining each item with proof, or accept and pay through DRC-03 and refer to the payment.
  • Time limit: reply within thirty days of receipt, extendable by the officer in appropriate cases.
  • If ignored: the officer can escalate to an audit, an inspection, or a show-cause notice and demand under Section 73, 74 or 74A.

01What a GST ASMT-10 is

Form GST ASMT-10 is a scrutiny notice. Under Section 61 of the CGST Act, read with Rule 99 of the CGST Rules, the proper officer may scrutinise your returns to verify that they are correct. If the officer finds a discrepancy, the officer issues an ASMT-10 asking you to explain it.

The important point is that an ASMT-10 seeks an explanation, not a payment. It is a chance to clear up a mismatch before it becomes a formal demand. Most ASMT-10 notices come from a simple difference between two returns or between a return and other data the department holds.

An inquiry, not a demand

An ASMT-10 does not create a liability on its own. It asks you to explain. If your explanation is accepted, the matter is closed. Treat it seriously, but do not panic.

02What it usually flags

Common discrepancies raised in an ASMT-10 include:

  • a mismatch between the outward supplies in your summary return and your detailed sales statement;
  • a difference between the input tax credit you claimed and the credit reflected in the auto populated statement;
  • tax shown as payable but not fully paid;
  • a mismatch between the value of supplies and the tax charged; or
  • differences between GST returns and other filings, such as income tax or e-way bill data.

The notice lists the specific discrepancy and the period. Your reply must address exactly what is listed, figure by figure.

03How to reply in Form ASMT-11

You reply to an ASMT-10 in Form ASMT-11 on the GST portal. There are two ways to respond, and you can combine them.

  1. Explain the discrepancy. Where you believe your return is correct, explain why, with supporting documents, reconciliations and reasons for each item.
  2. Accept and pay. Where the officer is right, accept the discrepancy, pay the tax and interest through DRC-03, and refer to that payment in your ASMT-11 reply.

A clear, item by item reply with a reconciliation is far more effective than a general denial. Where there is an obvious bona fide error, it is usually better to pay it early through DRC-03 and record in the ASMT-11 that it was a genuine mistake, not fraud. To see how that payment works, read how DRC-03 works.

04The time limit to reply

You should file your reply in Form ASMT-11 within thirty days of receiving the ASMT-10. The period can be extended by the officer in appropriate cases, but you should request any extension within the original period.

Always read the exact time stated in your own notice, because some notices mention a shorter period. If the officer accepts your explanation, the officer closes the scrutiny by issuing Form ASMT-12, and no further action follows on that point.

05What happens if you do not reply

If you do not reply within the time allowed, or your explanation is not satisfactory, the matter can escalate. The officer may:

  • start an audit under Section 65 or a special audit under Section 66;
  • order an inspection, search or seizure under Section 67; or
  • issue a show-cause notice and demand under Section 73, 74 or, for the financial year 2024-25 onwards, Section 74A.

In other words, the easy inquiry becomes a formal proceeding with penalties. If it reaches that stage, see the DRC-01 show-cause notice for how to reply to a demand.
