GST notices in India have surged 45% in FY25 per CBIC data, with Rs. 1.2 lakh crore demands issued. Forms ASMT-10 (inspection), DRC-01 (demand) signal compliance gaps; 18% interest + 100% penalty applies without reply. This guide lists top reasons, responses, and preventive frameworks.
12 Primary GST Notice Triggers
- GSTR-2A/3B Mismatch: Claimed ITC > supplier upload; Rule 36(4) caps 5%/10% auto-disallowance.
- Non-Reversal of ITC: Blocked credits on cars, food (Notification 49/2019); proportionate reversal ignored.
- E-Way Bill Violations: Interstate >Rs. 50k without bill; validity mismatch (1 day/200km).
- HSN/SAC Misclassification: 18% supplies coded 12%; differential demand + interest.
- Late/Non-Filing Returns: GSTR-1/3B delays trigger auto-SCN; Rs. 200/day cap Rs. 10k.
- Fake Invoices/Circular 183: Bogus suppliers; ITC denial + penalty = tax + 100%.
- Branch Transfer Errors: IGST not charged on stock transfers; treated as supply.
- Excess Composition Turnover: >1.5cr threshold breach; retrospective regular taxpayer.
- Wrong Place of Supply: SEZ supplies taxed IGST vs zero-rated.
- Reverse Charge Mechanism (RCM) Default: GTA, legal services unpaid 18%.
- E-Invoicing Lapses: >5cr turnover non-compliance post-1.8.2023.
- Annual Return Discrepancies: GSTR-9 vs portal data variances.
