Introduction
Getting an ASMT-10 notice from the GST department can feel worrying, but it does not always mean that you have done something wrong. In simple words, ASMT-10 is a GST scrutiny notice. The department sends it when it finds some difference or mismatch in your GST returns or records.
For example, your sales in GSTR-1 may not match with GSTR-3B, or your Input Tax Credit claimed in GSTR-3B may not match with GSTR-2B. Therefore, the GST officer asks you to explain the difference.
The good part is that you get a chance to reply. If you explain the matter properly with documents, the officer may accept your reply and close the notice. So, instead of panicking, you should check the notice carefully, prepare a point-wise reply, and submit it on the GST portal.
What Is an ASMT-10 Notice?
ASMT-10 is a notice issued by the GST department during scrutiny of returns. The GST officer issues this notice when he finds a difference in your GST returns, tax payment, Input Tax Credit, sales details, or other records available on the GST portal.
However, this notice is not a final demand notice. It is mainly a notice asking for clarification. Therefore, you need to explain the reason for the difference and submit supporting documents.
Why Does the GST Department Issue ASMT-10?
The GST department may issue ASMT-10 for many reasons. Some common reasons are:
- Difference between GSTR-1 and GSTR-3B
- Difference between GSTR-2B and ITC claimed in GSTR-3B
- Excess Input Tax Credit claimed
- Tax shown in GSTR-1 but not paid in GSTR-3B
- Difference between e-way bills and sales shown in returns
- Wrong GST rate used in invoices
- Difference due to credit notes or debit notes
- Short payment of tax or interest
- Mismatch in annual return and monthly or quarterly returns
- Supplier not reporting invoices on time
Therefore, you should first understand the exact reason mentioned in the notice before preparing the reply.
What Should You Do After Receiving ASMT-10?
First, do not ignore the notice. You should open the notice and read every point carefully.
Next, compare the notice details with your GST returns and books of accounts. You should check GSTR-1, GSTR-3B, GSTR-2B, purchase register, sales register, tax invoices, credit notes, debit notes, e-way bills, and payment proofs.
After that, prepare a point-wise reply. If the difference is correct, you may pay tax, interest, or other amount through DRC-03 and mention the payment details in your reply. However, if the difference is only due to a timing issue, supplier mistake, or amendment in later returns, you should explain it clearly.
Documents Required for ASMT-10 Reply
You may need the following documents while preparing the reply:
- Copy of ASMT-10 notice
- GSTR-1 summary
- GSTR-3B summary
- GSTR-2B details
- Purchase register
- Sales register
- Tax invoices
- Credit notes and debit notes
- E-way bill details, if applicable
- E-invoice details, if applicable
- Supplier ledger
- Customer ledger
- Bank payment proofs
- ITC reconciliation statement
- Sales reconciliation statement
- DRC-03 challan, if payment has been made
Important Points Before Preparing ASMT-10 Reply
You should always reply in a clear and polite manner. Also, you should not give a general reply like “all details are correct.” Instead, explain every mismatch separately.
Further, attach only relevant documents. If you attach many documents without explanation, the officer may not understand your case properly.
In addition, check whether the difference is due to a timing issue. Many times, invoices appear in GSTR-2B in the next month because the supplier filed GSTR-1 late. In such cases, you should explain the reason with invoice-wise reconciliation.

Respected Sir/Madam,
With reference to the notice issued in Form GST ASMT-10 for FY 2022-23, we respectfully submit our reply for your kind consideration.
We have verified the discrepancies mentioned in the notice with our books of accounts, GST returns, purchase register, sales register, GSTR-1, GSTR-3B, and GSTR-2B. After verification, we submit the following explanation:
Reply to Difference Between ITC Claimed in GSTR-3B and ITC Available in GSTR-2B
The notice mentions a difference between Input Tax Credit claimed in GSTR-3B and Input Tax Credit available in GSTR-2B.
In this regard, we submit that the difference occurred mainly because some suppliers filed their GSTR-1 after the due date. Due to this delay, a few invoices appeared in GSTR-2B of the next tax period.
However, the taxpayer received the goods, held valid tax invoices, made payment through banking channels, and used the goods for business purposes. Therefore, the ITC claim was genuine.
We have attached an invoice-wise reconciliation statement for your verification.
Documents attached:
- ITC reconciliation statement
- Purchase register
- Copies of tax invoices
- Supplier ledger
- Bank payment proof
- Relevant GSTR-2B extracts
Reply to Difference Between GSTR-1 and GSTR-3B
The notice also mentions a difference between outward supplies declared in GSTR-1 and tax paid in GSTR-3B.
In this regard, we submit that the difference occurred due to amendments and credit notes reported in subsequent returns. After considering these adjustments, there is no additional tax liability payable.
We have attached the sales reconciliation statement along with return summaries for your verification.
Documents attached:
- GSTR-1 summary
- GSTR-3B summary
- Sales register
- Credit note details
- Sales reconciliation statement
Final Submission
Based on the above explanation and supporting documents, we request your good office to kindly accept our reply and drop the proceedings initiated through Form GST ASMT-10.
