How Do You Reply to a GST ASMT-10 Notice?
To reply to a GST ASMT-10 notice, check the discrepancy mentioned by the GST officer, reconcile your GST returns with your books and supporting documents, and submit your explanation in Form GST ASMT-11 through the GST portal within the prescribed deadline. Under Rule 99 of the CGST Rules, the reply period cannot exceed 30 days from service of the notice unless a further period is permitted by the officer. If the discrepancy is accepted, pay the applicable dues and provide the payment details.
What Is a GST ASMT-10 Notice?
A GST ASMT-10 notice is a scrutiny notice issued by a proper officer under Section 61 of the Central Goods and Services Tax (CGST) Act, 2017, read with Rule 99 of the CGST Rules.
The notice informs a registered taxpayer about discrepancies identified during scrutiny of GST returns. It asks the taxpayer to explain the differences and, where possible, specifies the tax, interest or other amounts associated with them.
Receiving an ASMT-10 notice does not automatically mean that a final tax demand has been raised. It gives you an opportunity to explain the discrepancy or accept it and take the appropriate corrective action.
Common discrepancies include:
- Differences between GSTR-1 and GSTR-3B.
- Differences between input tax credit (ITC) claimed in GSTR-3B and credit reflected in GSTR-2B.
- Differences between reported turnover and information available from e-way bills or other records.
- Incorrect tax rates, missed invoices or reporting errors.
- Differences between GST returns and financial statements.
- Incorrectly reported credit notes, debit notes or taxable supplies.
The appropriate response depends on the actual discrepancy, the relevant tax period and the supporting evidence. Refer to Rule 99 of the CGST Rules for the statutory framework.
Who Can Receive a GST ASMT-10 Notice?
A GST-registered business may receive an ASMT-10 notice when its returns are selected for scrutiny and the officer identifies discrepancies requiring an explanation.
The notice may concern manufacturers, traders, service providers, e-commerce businesses or other registered taxpayers.
For example, suppose a business reports taxable outward supplies of ₹12 lakh in GSTR-1 but declares ₹10 lakh in the corresponding GSTR-3B. The difference may arise from a genuine timing issue, a missed invoice, an amendment or an error.
The officer may ask the taxpayer to explain the ₹2 lakh difference. The taxpayer should investigate the underlying records before accepting the discrepancy or disputing the officer’s calculation.
Important: A mismatch is not, by itself, proof of tax evasion. However, an unexplained difference should not be ignored.
What Is the Difference Between GST ASMT-10, ASMT-11 and ASMT-12?
| GST Form | Purpose |
|---|---|
| GST ASMT-10 | Communicates discrepancies identified during scrutiny of returns. |
| GST ASMT-11 | Allows the taxpayer to explain the discrepancy or report the relevant corrective action and payment. |
| GST ASMT-12 | Communicates acceptance of the taxpayer's explanation or response and conclusion of the scrutiny proceedings. |
ASMT-10 is the notice, ASMT-11 is the taxpayer’s reply, and ASMT-12 is the order communicating acceptance where applicable.
If the explanation is not accepted, or the taxpayer fails to respond appropriately, the officer may initiate further action under the applicable provisions. This can include demand proceedings, audit or investigation, depending on the circumstances.

What Is the GST ASMT-10 Notice Reply Deadline?
Under Rule 99(1) of the CGST Rules, the notice specifies the period for providing an explanation, which cannot exceed 30 days from the date of service of the notice unless a further period is permitted by the proper officer.
| Particular | What Taxpayers Should Know |
|---|---|
| Reply Form | GST ASMT-11 |
| General Statutory Maximum for the Initial Reply Period | 30 days from service of the notice |
| Extension | A further period may be permitted by the proper officer. |
| Where the Reply Is Accepted | The officer communicates acceptance in ASMT-12. |
| Where the Reply Is Unsatisfactory or Absent | Further proceedings may be initiated under applicable provisions. |
Do not calculate your deadline solely from the date printed on the notice. Check the date and manner of service, the reply date specified in the notice, and any subsequent extension granted by the officer.
The administrative scrutiny procedure also depends on the relevant financial year. CBIC Instruction No. 02/2023-GST dated 26 May 2023 addresses scrutiny of returns for FY 2019-20 onwards and modifies the earlier SOP for FY 2017-18 and FY 2018-19.
For this reason, a CA should verify the applicable scrutiny instructions and current procedure before advising on a specific notice.
Official reference: CBIC Instruction No. 02/2023-GST.
Is There a Late Fee or Automatic Penalty for Not Replying to ASMT-10?
Rule 99 does not prescribe a separate fixed late-reply fee simply for missing the ASMT-10 response deadline. However, ignoring the notice can expose the taxpayer to further scrutiny, audit or demand proceedings.
If a tax liability is established, interest and penalties may apply under the relevant legal provisions and facts. These amounts should not be confused with a separate automatic penalty merely for filing an ASMT-11 late.
If you cannot prepare the reply on time, request an extension from the proper officer before the deadline expires. An extension is not automatic, so retain the request and any approval.
How to Reply to a GST ASMT-10 Notice Online: Step-by-Step Process
Follow these steps to prepare and submit your GST ASMT-10 notice reply.
Step 1: Open the Notice on the GST Portal
Log in to the official GST portal using your authorised credentials.
Navigate to the notices and orders section, commonly accessible through Services and the relevant user-services menu. Open the ASMT-10 notice and download its attachments, discrepancy worksheets and supporting documents.
Check the following details:
- GSTIN and legal name.
- Financial year and tax period.
- Notice reference number and date.
- Each discrepancy and the amount involved.
- Reply deadline and any hearing or communication details.
Portal menus can change, so follow the current interface and the options available for your case.
Step 2: Understand Each Discrepancy
Do not prepare a generic reply before understanding the officer’s observations.
For every issue, identify the amount in question, the return or record being compared, the possible cause of the mismatch and the evidence needed to explain it.
For example, a difference between GSTR-1 and GSTR-3B might relate to an amended invoice or a credit note. A difference between GSTR-2B and GSTR-3B may require an invoice-level ITC reconciliation and an eligibility review.
Step 3: Reconcile GST Returns With Your Books
Prepare a working paper showing the figures reported in the relevant returns and the corresponding accounting records.
Depending on the discrepancy, review:
- GSTR-1 and GSTR-3B.
- GSTR-2B and the purchase register.
- Sales and purchase ledgers.
- Tax invoices, debit notes and credit notes.
- E-way bills and e-invoice records, where applicable.
- Bank statements and payment records, where relevant.
- Earlier corrections and voluntary tax payments.
Clearly distinguish genuine timing differences, clerical mistakes, already-corrected discrepancies and amounts that may actually be payable.
Step 4: Decide Whether to Accept or Dispute the Discrepancy
There are two broad approaches.
If the discrepancy is incorrect: Explain why the officer’s calculation does not reflect the underlying transactions. Attach a reconciliation statement and supporting evidence.
If the discrepancy is correct: Determine the tax, interest and any other applicable amount. Take the appropriate corrective or payment action, then disclose the relevant details in the ASMT-11 response.
If only part of the discrepancy is correct, explain the admitted and disputed amounts separately.
Do not make a payment merely because a notice mentions a figure. Verify the liability and the legally appropriate payment or correction procedure first.
Step 5: Prepare Your GST ASMT-11 Reply
Draft a clear response that follows the order of the discrepancies in ASMT-10.
For each observation, state the officer’s allegation, your explanation, the amount involved and the documents supporting your position.
Avoid vague statements such as “the difference is due to a technical error” without explaining the error or providing evidence.
Step 6: Upload Supporting Documents
Organise the documents with clear filenames and an annexure index.
A useful structure is:
- Annexure A: GST return reconciliation.
- Annexure B: Relevant tax invoices and credit notes.
- Annexure C: Purchase or sales ledger extracts.
- Annexure D: Payment challans and DRC-03 details, if applicable.
- Annexure E: Additional evidence relevant to the discrepancy.
Upload the documents in the format and within the size limits specified by the GST portal.
Step 7: Submit and Save the Acknowledgement
Enter the response and required details in the ASMT-11 workflow available for the notice.
Review the completed response, verify the authorised signatory details, and submit it using the prescribed verification method.
Download or save the filed reply and acknowledgement or reference number. Check the case status and monitor subsequent notices or orders.
A draft saved on your computer is not proof that the reply has been filed.
What Documents Are Required for a GST ASMT-10 Notice Reply?
The documents depend on the issue raised in the notice. Not every taxpayer needs to submit every document listed below.
| Discrepancy | Documents to Consider |
|---|---|
| GSTR-1 vs GSTR-3B Mismatch | Both returns, sales register, invoices, credit notes and reconciliation statement |
| GSTR-2B vs GSTR-3B Mismatch | GSTR-2B, purchase register, tax invoices, supplier details and ITC working |
| Turnover Mismatch | Financial statements, trial balance, sales ledger and GST returns |
| E-Way Bill Mismatch | E-way bills, invoices, delivery records and cancellation or amendment evidence |
| Tax Already Paid | Challan, DRC-03 details, payment reference and relevant ledger entries |
| Incorrect Tax Classification or Rate | Invoices, product or service details and relevant legal provisions |
Only attach relevant, authentic records. If a document contains confidential business information, ensure that its disclosure is appropriate for the proceedings.

What Happens If You Ignore a GST ASMT-10 Notice?
Ignoring an ASMT-10 notice does not make the discrepancy disappear.
Under the scrutiny framework, the officer may initiate appropriate further action where the taxpayer fails to provide a satisfactory explanation or fails to take the required corrective action after accepting a discrepancy.
Depending on the case, the next step may include:
- A show cause notice under the applicable demand provisions.
- Proceedings to determine tax, interest and penalty where legally justified.
- Audit or special audit under the relevant provisions.
- Further investigation or other action permitted by law.
An ASMT-10 notice is different from a DRC-01 show cause notice. The latter is associated with formal demand proceedings. The exact legal route depends on the financial year, the nature of the alleged discrepancy and the provisions applicable to the case.
If you have already received a DRC-01, do not assume that submitting a late ASMT-11 reply alone will resolve the later proceeding. Review each notice separately and meet its own response requirements.
Common Mistakes to Avoid When Replying to ASMT-10
- Missing the deadline: Check the date of service and request an extension where necessary.
- Submitting a generic reply: Answer every discrepancy separately.
- Ignoring the reconciliation: Support your explanation with return data and accounting records.
- Admitting the full amount without verification: Separate correct, incorrect and timing-related differences.
- Paying without checking the liability: Verify the amount and appropriate payment route.
- Uploading incomplete evidence: Include relevant documents and a clear annexure index.
- Failing to save proof of filing: Keep the filed reply and acknowledgement.
- Ignoring later communications: Monitor the portal for an acceptance order, further notice or other action.
