GST notice received, which form and what to do.
GST notices in India come in multiple forms — ASMT-10, DRC-01, DRC-01A, GSTR-3A, mismatch alerts — each with different response windows and consequences. Non-response or wrong response can convert a routine query into a tax demand plus 100% penalty. Here is the practitioner's response map.

/ Common GST notice types + response window
The map.
ASMT-10 (Notice of Discrepancy): issued by proper officer under Section 61 if return filed differs from information available. Response window: typically 30 days. Response via ASMT-11. Non-response: officer proceeds with audit under Section 65 or scrutiny.
DRC-01A (Pre-SCN Intimation): issued under Section 73(5) or 74(5) before formal SCN. Specifies proposed demand + reasons. Response window: typically 15 days. Response via DRC-03 (paying tax + interest voluntarily to close) or DRC-06 (contesting). Advantage of DRC-03: reduced penalty if voluntarily paid before SCN.
DRC-01 (Show Cause Notice under Section 73/74): formal SCN proposing tax demand. Section 73 (bona fide errors): penalty 10% or INR 10,000 whichever higher; 3-year time limit. Section 74 (fraud / wilful misstatement): penalty 100%; 5-year time limit. Response window: typically 30 days. Response via DRC-06.
GSTR-3A (Notice for Non-filing of Return): issued to taxpayer who has not filed GSTR-3B / GSTR-1 for one or more months. Response: file pending returns within 15 days or face Section 62 best-judgment assessment.
GSTR-2A / 2B vs GSTR-3B mismatch alerts: auto-generated by portal when ITC claimed in 3B exceeds reconciled 2B figures. Response: reconcile vendor-wise, chase vendors for missing invoices, reverse ineligible ITC.
Audit notice under Section 65 (ADT-01): formal audit of records. Response: provide records; audit completed within 3 months (extendable to 6).
/ GSTR-2A / 2B vs GSTR-3B mismatch
The most common GST headache.
Mechanism: ITC can be claimed in GSTR-3B only if the vendor has filed GSTR-1 showing the supply to you. GSTR-2A (dynamic) and GSTR-2B (static month-close snapshot) reflect what vendors have reported.
Mismatch types:
- Vendor has not filed GSTR-1 — invoice does not appear in your 2B. Your 3B ITC is excess vs 2B. Portal flags mismatch.
- Vendor filed GSTR-1 but with wrong GSTIN — invoice shows against someone else.
- Vendor filed GSTR-1 but delayed — invoice appears in a later month's 2B than when you claimed ITC.
- You claimed ITC on exempt / blocked supplies — e.g., personal use, Section 17(5) blocks (motor vehicles, construction materials for own buildings).
Response path:
- Download GSTR-2B for the mismatch period. Match line-by-line with your purchase register.
- Identify vendors who have not reported. Chase for GSTR-1 filing.
- If vendor is unresponsive, reverse the ITC in next GSTR-3B (reversal with interest under Section 50).
- If ITC was wrongly claimed on blocked / exempt supplies, reverse via GSTR-3B Table 4(B).
- If mismatch is timing (vendor filed in later month), no action needed — ITC will match in the later period.
- Document the reconciliation in GSTR-9 annual return.
/ Section 73 vs Section 74
The crucial distinction.
Section 73: applies to bona fide errors, oversight, interpretation differences. No fraud alleged.
- Time limit: SCN within 3 years of due date of annual return (so for FY 2024-25, within 31 December 2028).
- Penalty: 10% of tax or INR 10,000, whichever higher.
- Voluntary payment via DRC-03 before SCN: nil penalty.
- Payment within 30 days of SCN: no penalty (interest only).
Section 74: applies to fraud, wilful misstatement, suppression of facts.
- Time limit: SCN within 5 years of due date of annual return.
- Penalty: 100% of tax.
- Voluntary payment via DRC-03 before SCN: 15% penalty.
- Payment within 30 days of SCN: 25% penalty.
- Beyond 30 days: full 100% penalty.
Section 73 vs 74 classification is often the key battle. Convert a 74 to 73 and penalty drops from 100% to 10%. Response strategy focuses on establishing bona fide error (interpretation, no suppression) and challenging the fraud allegation.
/ Response workflow
Standard engagement.
- Read the notice carefully: identify form (ASMT, DRC-01A, DRC-01), the specific issue, response window, proposed demand amount, Section 73 or 74.
- Pull GST records: GSTR-1 filed, GSTR-3B filed, GSTR-2A / 2B for the period, purchase register, sales register, GSTR-9 annual return.
- Analyze the discrepancy: identify where the Department's view differs from yours.
- Decide response strategy: pay-and-close (via DRC-03) if demand is correct, or contest (via DRC-06) with documents.
- Draft response addressing each issue in the notice with supporting evidence.
- File response via GST portal within the deadline.
- Attend personal hearing if called (physical or virtual depending on jurisdiction).
- Appeal to CGST Appellate Authority within 3 months if adjudication order is adverse.

GST notice received? Form matters, time matters.
Working-CA engagement: identify form (ASMT / DRC-01A / DRC-01), analyze the specific issue, decide pay-and-close vs contest strategy, file response within deadline. For Section 74 notices, converting to Section 73 can drop penalty from 100% to 10%.
