Most MSMEs in Coimbatore and Tamil Nadu receive at least one GST notice every year — and most ignore them until it's too late. A notice that could have been resolved with a ₹5,000 response often snowballs into a ₹50,000+ liability with interest, late fees, and blocked Input Tax Credit. Here are the 5 notices you must never ignore.
1. GSTR-3A — Notice for Non-Filing of Returns
What it is: An auto-generated notice when you miss filing GSTR-1, GSTR-3B, or the annual return GSTR-9.
Cost if ignored:
Late fee of ₹50 per day (₹20 for nil returns), capped at ₹10,000 per return
18% interest per annum on any unpaid tax
Best-judgement assessment under Section 62 — the officer can raise a demand based on estimated turnover
ITC freeze — your buyers lose ITC, damaging business relationships
Typical 3-month ignore cost: ₹45,000 – ₹80,000 per return period
How to respond: File the pending return immediately along with late fee and interest. If you received a best-judgement assessment order, file the return within 30 days to automatically cancel it.
2. DRC-01 — Show Cause Notice for Tax Demand
What it is: Issued under Section 73 (non-fraud) or Section 74 (fraud cases) when the officer believes tax has been short-paid, unpaid, or ITC wrongly availed.
Cost if ignored:
100% penalty under Section 74 (fraud cases) equal to tax amount
Up to 25% penalty under Section 73 if not paid within 30 days
18% interest from original due date
Recovery proceedings including bank account attachment
Typical SME hit: ₹60,000 – ₹2,00,000 on a ₹50,000 disputed tax
How to respond: You have 30 days to file a reply with supporting evidence. Paying tax + interest within this window reduces penalty to zero (Section 73) or 15% (Section 74).
3. ASMT-10 — Notice for Discrepancy in Returns
What it is: Sent when the GST department finds mismatches between GSTR-1, GSTR-3B, GSTR-2A/2B, or e-way bill data.
Cost if ignored:
Escalation to DRC-01 with full demand + penalty
ITC reversal with interest @ 18%
Blocking of future ITC claims
Typical ignore cost: ₹35,000+ on a small ₹15,000 mismatch
How to respond: File ASMT-11 within the timeline specified (usually 30 days) explaining the discrepancy with reconciliation statements and documentary evidence.
4. REG-17 — Notice for Cancellation of GST Registration
What it is: Issued when the department suspects fraud, continuous non-filing, or non-existence at the registered address.
Cost if ignored:
GSTIN cancelled retrospectively
All outward supplies become unregistered → 18% additional tax liability on past invoices
Loss of all accumulated ITC
Fresh registration required with scrutiny
Typical cost: ₹1,00,000+ in retrospective tax on just 6 months of turnover
How to respond: File REG-18 within 7 working days with documentary evidence (electricity bill, rent agreement, bank statement) and clarifications.
5. DRC-07 — Summary of Order / Recovery Notice
What it is: The final recovery order after DRC-01 goes unanswered. This is the "last warning" before enforcement.
Cost if ignored:
Immediate bank account attachment
Garnishee proceedings against your debtors
Property attachment and auction
Criminal prosecution in fraud cases (Section 132)
How to respond: Pay the demand immediately or file an appeal under Section 107 within 3 months (with pre-deposit of 10% disputed tax).
The Hidden Cost: ITC Blockage
Every one of these notices, if unresolved, can trigger Rule 86A — blocking your electronic credit ledger. Your business effectively runs on zero working capital for months.
