GST notices and demands are becoming increasingly common as the GST department uses advanced data analytics to identify mismatches, short payments, and ITC irregularities. A GST notice can range from a routine clarification request to a substantial tax demand with penalties. Responding correctly and on time is critical — a wrong response can escalate a small mismatch into a large demand. This guide explains the most common GST notices, what triggers them, and how to handle them effectively.

1. Most Common GST Notices
| Form | Purpose | Common Trigger |
|---|---|---|
| ASMT-10 | Scrutiny notice — seeking clarification | Mismatch between GSTR-1 and GSTR-3B; ITC discrepancy; turnover mismatch with AIS |
| DRC-01A | Pre-show cause notice for demand | Officer proposes tax demand — taxpayer gets chance to pay before formal SCN issued |
| DRC-01 | Show Cause Notice (SCN) for demand | Tax short-paid, ITC wrongly claimed, supply not declared |
| REG-03 | Clarification during registration | Incomplete documents or inconsistencies in GST registration application |
| REG-17 | Show Cause Notice for cancellation | Returns not filed for 6+ months, fake invoicing, non-existent business address |
| CMP-05 | Notice under Composition Scheme | Composition taxpayer suspected of making inter-state or ineligible supplies |
| GST ADT-01 | Notice of Audit (Section 65) | Departmental audit of GST records at taxpayer's premises |
DRC-01A is your last chance to pay voluntarily before a formal Show Cause Notice. Paying at DRC-01A stage avoids the 100% penalty. Act immediately.
DRC-01A Urgent Help →2. Top GST Notice Triggers in India Today
- GSTR-1 vs GSTR-3B mismatch: Sales declared in GSTR-1 differ from tax paid in GSTR-3B — automated mismatch notice
- ITC mismatch (GSTR-2B vs GSTR-3B): ITC claimed in GSTR-3B exceeds what is available in GSTR-2B
- GST turnover vs IT return turnover: Large discrepancy between GST turnover and income declared in ITR triggers cross-department data sharing notices
- ITC on blocked credits (Section 17(5)): ITC claimed on ineligible items — motor vehicles, food, personal expenses
- RCM non-compliance: GST not paid under Reverse Charge on GTA services, import of services, legal services, etc.
- E-invoicing non-compliance: B2B invoices not registered on IRP by eligible taxpayers
- HSN/SAC code mismatch: Wrong HSN leading to lower tax rate applied than applicable
- Fake ITC (Section 16(2)(c)): ITC claimed from suppliers who did not pay tax to the government
3. GST Penalty Structure
| Offence | Penalty |
|---|---|
| Short payment / non-payment of tax (genuine error) | 10% of tax due (min ₹10,000) + interest at 18% p.a. |
| Short payment / non-payment (fraud / suppression) | 100% of tax due + interest at 18% p.a. |
| Wrongful ITC claim (fraud) | 100% of ITC wrongly availed + interest |
| Failure to register (when mandatory) | 10% of tax due (min ₹10,000) |
| Issuance of invoice without supply (fake invoice) | 100% of tax involved |
4. How to Handle a GST Notice Effectively
- Act within deadline: GST notices have strict deadlines — 7, 15, or 30 days depending on type. Missing the deadline means the demand is confirmed ex-parte.
- Understand what's being asked: Read the notice carefully — is it asking for data/documents (ASMT-10) or proposing a demand (DRC-01/DRC-01A)?
- Prepare complete documentation: GSTR-1/3B/2B data, purchase invoices, payment proofs, bank statements, reconciliation statements
- File response on GST portal: All responses submitted online through the GST portal under the relevant section
- Pay undisputed amounts promptly: Paying the undisputed portion reduces interest burden and often leads to faster resolution of the disputed portion
- Appeal if order is unfavourable: Appeal to Appellate Authority (within 3 months of order), then GST Appellate Tribunal, then High Court
