ASMT-11 is the official GST form used to reply to a scrutiny notice (ASMT-10) issued by the tax officer under Section 61 of the CGST Act. It is meant for registered taxpayers whose GST returns have been flagged for discrepancies. Filing a prompt, well-documented ASMT-11 response can prevent penalties, additional tax demands, and even GST registration cancellation.

• Reply must be filed within 30 days of receiving ASMT-10 (extendable on application)
• Filed online on the GST portal – no physical submission required
• A satisfactory reply closes the scrutiny; an unsatisfactory one can escalate to adjudication under Section 73/74

What is ASMT-10?

ASMT-10 is a scrutiny notice issued by the GST officer when discrepancies are detected in a taxpayer's filed returns — such as mismatches between GSTR-1 and GSTR-3B, excess ITC claims, or turnover inconsistencies. The notice calls for an explanation of the discrepancy within a specified time. ASMT-11 is the taxpayer's formal, structured reply to this notice.

What is ASMT-11 in GST?

ASMT-11 is the statutory reply form under Rule 99(2) of the CGST Rules, 2017, filed on the GST common portal in response to ASMT-10. It allows the taxpayer to provide clarifications, supporting documents, and reconciliation statements to satisfy the tax officer that the discrepancy pointed out in the scrutiny notice has a valid explanation — or to accept the discrepancy and pay the differential tax with interest.

Common Reasons for Receiving ASMT-10

The GST department uses ASMT-10 in situations where automated or manual scrutiny reveals inconsistencies. Understanding the root cause is the first step to drafting a strong ASMT-11 reply.

• GSTR-1 vs GSTR-3B mismatch: Outward supplies declared in GSTR-1 differ from GSTR-3B
• ITC mismatch: Input tax credit claimed in GSTR-3B exceeds what appears in GSTR-2B
• Turnover discrepancy: Revenue reported in GST returns differs from income tax or e-way bill data
• Excess ITC on ineligible items: ITC claimed on items blocked under Section 17(5)
• HSN code mismatch: HSN codes on invoices differ from those reported in returns
• E-invoice non-compliance: E-invoices not generated despite crossing the applicable threshold turnover
• Outward supply vs e-way bill data: Discrepancy between supplies declared and e-way bill records

Each of these issues requires a tailored ASMT-11 response. You can read more about specific notice types in our detailed guides on scrutiny notices for GST return discrepancies and ITC difference notices between GSTR-3B and GSTR-2B.

How to File ASMT-11 on the GST Portal (2026)

Filing ASMT-11 is a fully online process on the GST common portal. Follow these steps carefully to ensure your reply is submitted correctly and on time.

Step 1 – Log in to GST Portal

Go to www.gst.gov.in and log in with your GSTIN credentials.

Step 2 – Navigate to the Notice

Go to Services > User Services > View Additional Notices / Orders. Locate your ASMT-10 notice under the relevant financial year.

Step 3 – Click "Reply"

Click on the notice reference and select the "Reply" option. The system will open the ASMT-11 form pre-filled with your GSTIN, notice reference number, and the period under scrutiny.

Step 4 – Draft Your Reply

In the "Reply" text field, explain the discrepancy point by point. Clearly state whether you: (a) accept the discrepancy and wish to pay the differential tax with interest, or (b) dispute the discrepancy with supporting evidence. Keep the language factual and specific — vague replies are commonly rejected.

Step 5 – Upload Supporting Documents

Attach relevant documents such as reconciliation statements, purchase/sale registers, bank statements, supplier invoices, or e-way bills. The portal accepts PDF and JPG files up to the prescribed size limit.

Step 6 – Submit Using DSC or EVC

Submit the ASMT-11 form using your Digital Signature Certificate (DSC) (mandatory for companies and LLPs) or Electronic Verification Code (EVC) for other taxpayers. After submission, an acknowledgement number is generated — save it for records.

Once the officer reviews your reply, they can either close the proceedings by issuing an ASMT-12 (acceptance order) or escalate to an adjudication notice under Section 73 or 74 of the CGST Act.

What Should Your ASMT-11 Reply Include?

A well-drafted ASMT-11 can make the difference between case closure and an escalating demand. Here is what every reply should cover:

• Reference to ASMT-10: Clearly quote the notice number, date, and the specific discrepancy raised
• Point-by-point rebuttal or acceptance: Address each discrepancy individually — do not give a generic reply
• Reconciliation statement: A tabular comparison of the figures in question with your books and the reason for any variance
• Supporting evidence: Invoices, credit/debit notes, supplier filing confirmations, bank statements
• Legal grounds (if disputing): Cite the relevant provisions of the CGST Act or CGST Rules if you are contesting the department's interpretation
• Payment details (if accepting): If you are accepting the liability, mention the DRC-03 challan reference used to pay the differential tax and interest

What Happens If You Don't Reply to ASMT-10?

Ignoring an ASMT-10 notice or missing the 30-day reply deadline is a serious compliance failure. If no satisfactory reply is filed in ASMT-11, the GST officer is empowered to proceed with best-judgment assessment under Section 62 of the CGST Act — meaning tax, interest, and penalty can be imposed based on available information, without the taxpayer's input.

Possible consequences include:

• Adjudication proceedings under Section 73 (non-fraud) or Section 74 (fraud/wilful suppression)
• Tax demand with interest under Section 50 of the CGST Act
• Penalty up to 100% of the tax amount in fraud cases (Section 74)
• Risk of GST registration suspension or cancellation — see our guide on GST registration cancellation for non-compliance

If you need an extension beyond 30 days, you can apply to the officer before the deadline expires.

Frequently Asked Questions

What is the time limit to file ASMT-11?

The taxpayer must file ASMT-11 within 30 days of receiving the ASMT-10 scrutiny notice. An extension can be requested from the tax officer before the 30-day period expires. Missing the deadline without extension can lead to best-judgment assessment under Section 62 of the CGST Act.

Is ASMT-11 filed online or offline?

ASMT-11 is filed entirely online through the GST common portal at www.gst.gov.in. Navigate to Services > User Services > View Additional Notices / Orders, locate the ASMT-10 notice, and click "Reply" to open and submit ASMT-11. No physical submission is required.

What happens after ASMT-11 is submitted?

After you submit ASMT-11, the tax officer reviews your reply and supporting documents. If satisfied, the officer closes the proceedings by issuing ASMT-12 (an acceptance order). If not satisfied, the officer may initiate adjudication proceedings under Section 73 or Section 74 of the CGST Act and issue a formal show cause notice.

What if I accept the discrepancy in ASMT-11?

If you accept the discrepancy, you must pay the differential tax along with applicable interest using Form DRC-03 on the GST portal. Mention the DRC-03 challan reference number in your ASMT-11 reply. Accepting and paying promptly typically results in quicker case closure and avoids further penalty proceedings.

Do I need a professional to file ASMT-11?

While any registered taxpayer can file ASMT-11 themselves, the quality of the reply is critical. Poorly drafted replies or missing documentation are the primary reasons notices escalate into demand proceedings. Engaging a GST expert significantly improves the chance of a favourable closure. Taxocity's GST team handles ASMT-11 filings with full documentation support.
