Received a GST Notice (ASMT-10, DRC-01B, or DRC-01C)? Step-by-Step Guide to Filing Your Reply
If you have logged into the GST Portal recently or checked your registered email, receiving an automated scrutiny notice under Form GST ASMT-10, DRC-01B, or DRC-01C can be alarming. The GST department’s data-analytics engine automatically flags discrepancies between your filed returns. Failing to respond correctly within the mandatory deadline can lead to portal blocking, recovery proceedings, and high interest penalties.
In this guide, the tax compliance specialists at JINI Associates explain why these notices are issued, the key differences between them, and how to draft a legally sound reply.
⚠️ IMPORTANT DEADLINE WARNING: DRC-01B and DRC-01C notices typically carry a strict 7-day timeline. Ignoring them can result in automatic blocking of your GSTR-1 / IFF filing capabilities for subsequent tax periods.
1. Decoding the 3 Most Common Automated GST Mismatch Notices
The GST system automatically cross-examines data across your monthly returns. Here is how to identify which notice you have received:
| Notice Type | Trigger Cause | Key Discrepancy | Mandatory Reply Form |
|---|---|---|---|
| Form GST ASMT-10 | Scrutiny of Returns (Section 61) | General tax liability or ITC differences flagged by proper officer. | Form GST ASMT-11 |
| Form GST DRC-01B | Rule 88C Automated Intimation | Outward liability in GSTR-1 is higher than reported in GSTR-3B. | DRC-01B (Part B) |
| Form GST DRC-01C | Rule 88D Automated Intimation | Input Tax Credit (ITC) claimed in GSTR-3B exceeds available credit in GSTR-2B. | DRC-01C (Part B) |
2. Common Reasons Behind GSTR-1 vs 3B and ITC Discrepancies
Before responding, you must audit your books of accounts to pinpoint why the discrepancy occurred. The most frequent causes include:
- Data Entry Typographical Errors: Misplacing numbers between taxable value and tax amount during manual filing.
- Timing Differences in Debit/Credit Notes: Issuing credit notes in a subsequent month that wasn’t reconciled during the filing period.
- Non-Filing by Vendors: Claiming ITC on purchases where your supplier failed to file their GSTR-1 on time, causing a GSTR-2B deficit.
- Duplicate Tax Payment: Unintentionally reporting the same invoice twice in GSTR-1 while correcting it in GSTR-3B.
- Ineligible ITC Reversals: Omitting permanent ITC reversals required under Rules 37, 38, 42, or 43.
3. Step-by-Step Action Plan: How to Reply to Your GST Notice
Step 1: Download and Audit the Detailed Breakdown
Log in to the GST Portal, navigate to Services > User Services > View Additional Notices/Orders. Download the system-generated PDF along with the detailed table of invoice mismatches.
Step 2: Perform Month-Wise Invoice Reconciliation
Compare your internal Tally/ERP sales and purchase registers directly against GSTR-1, GSTR-3B, and GSTR-2B. Identify whether the difference is an actual tax shortage or a reconciliation timing error.
Step 3: Pay the Differential Tax (If Actual Shortfall Exists)
If the tax discrepancy is valid (e.g., forgotten sales invoice or incorrect ITC claim):
- Pay the differential tax along with applicable interest under Section 50 using Form GST DRC-03.
- Save the ARN receipt of the DRC-03 payment.
Step 4: Draft and Submit Form GST ASMT-11 / DRC-01B (Part B)
If the discrepancy is explainable or already resolved, draft a point-by-point factual response:
- Select the appropriate reason code provided on the portal menu (e.g., "Tax paid in previous month" or "Vendor filed late").
- Provide explicit details along with supporting documents (invoices, credit notes, or reconciliation spreadsheets).
- Include your DRC-03 ARN if tax was paid.
4. What Happens If You Ignore or Delay Your Reply?
The GST system has shifted towards strict automated enforcement. Failing to reply within the stipulated time frame leads to:
- Automatic GSTR-1 Blocking: Rule 88C/88D prevents you from filing subsequent outward supply returns until the discrepancy is resolved.
- Initiation of Section 73 / Section 74 Proceedings: The department will issue a formal Show Cause Notice (SCN) with statutory penalty charges ranging from 10% to 100%.
- Interest Accumulation: Interest under Section 50 continues to compound at 18% per annum on unpaid tax liabilities.
