How to Reply to a GST Notice: A Practical Guide

Receiving a GST notice is stressful, but most notices are routine queries that can be closed with a clear, documented reply. Knowing how to reply to a GST notice starts with identifying what kind of notice it is, because each form has its own purpose, timeline and reply format. A mismatch intimation needs a quick explanation or payment; a scrutiny notice needs reconciliations; a show cause notice needs a structured legal response, often with your CA's help. This guide covers the common notices, where to find them, a step-by-step reply process and the mistakes that turn small queries into demands.

First steps when a notice arrives

1. Verify it. Log in to the GST portal and check Services, User Services, View Notices and Orders, or the Additional Notices and Orders tab. CBIC notices carry a Document Identification Number (DIN) that can be verified on the CBIC website. Be wary of emails or messages asking for payments to unofficial accounts.
2. Identify the form and section. The form number (ASMT-10, DRC-01B, DRC-01 and so on) tells you the stage and the response required.
3. Note the due date. Many notices allow 7, 15 or 30 days. Put the date in your calendar immediately.
4. Read the specific allegation. Note the period, the amount and the basis (for example, ITC in GSTR-3B higher than GSTR-2B).
5. Involve your CA early for anything beyond a simple mismatch intimation.

Common GST notices and what they mean

Form	Purpose	Typical response window
REG-03	Clarification sought on a registration application	7 working days, reply in REG-04
REG-17 / REG-31	Show cause for cancellation, or intimation of suspension	As stated, usually 7 to 30 days
DRC-01B	Liability in GSTR-1 exceeds GSTR-3B beyond a threshold	7 days, reply in Part B
DRC-01C	ITC claimed in GSTR-3B exceeds GSTR-2B beyond a threshold	7 days, reply in Part B
ASMT-10	Scrutiny of returns: discrepancies found by the officer	30 days or as specified, reply in ASMT-11
ADT-01	Notice of audit by the department	As scheduled
DRC-01A	Pre-show cause intimation of tax ascertained	As specified, reply in Part B
DRC-01	Show cause notice for tax demand	Usually 30 days, reply in DRC-06
DRC-07	Summary of demand order	Pay or appeal within the appeal period

Notices for older years fall under sections 73 and 74. For FY 2024-25 onwards, a unified section 74A applies with a common timeline for issuing notices and orders, with penalty depending on whether fraud or suppression is alleged.

Replying to mismatch intimations (DRC-01B and DRC-01C)

These are system-generated and require a fast response. If you do not respond, the portal may block filing of your next GSTR-1.

DRC-01B: output liability mismatch

• Pay the differential tax through DRC-03 and quote the payment reference, or
• Explain the difference: for example, invoices reported in GSTR-1 for a month but tax paid in a later GSTR-3B, credit notes not yet reported, or amendments.

DRC-01C: ITC mismatch

• Reverse the excess ITC through DRC-03 or in the next GSTR-3B, or
• Explain: for example, ITC on imports from customs data, ISD credit, credit of a previous month's GSTR-2B claimed now, or RCM credit.

Keep a month-wise reconciliation ready. The method in our GSTR-2B reconciliation guide is what an officer expects to see.

Replying to a scrutiny notice (ASMT-10)

Scrutiny notices usually point to differences between your returns and other data: GSTR-1 versus GSTR-3B, GSTR-3B ITC versus GSTR-2B, e-way bill values versus returns, or turnover in your income-tax return versus GST returns.

Step-by-step reply

1. List each discrepancy in the notice.
2. Prepare a reconciliation for each, using source documents: invoices, credit notes, GSTR-2B extracts, e-way bills and ledgers.
3. Categorise each difference as explained (timing, classification, data entry), accepted (pay with interest), or disputed (with legal basis).
4. Pay accepted amounts through DRC-03 with interest before replying.
5. Draft the reply in ASMT-11 with a summary table and annexures.
6. File on the portal and keep the acknowledgement.

If the officer accepts the explanation, the matter is closed with ASMT-12. If not, the officer may initiate audit, investigation or a show cause notice.

Replying to a show cause notice (DRC-01)

A show cause notice is a formal proposal of demand. The reply in DRC-06 should be structured and evidence-based:

1. Preliminary objections: limitation (whether the notice is within time), jurisdiction, and whether proper procedure was followed.
2. Facts: your business, the transactions in question and the timeline.
3. Point-wise response: for each allegation, the facts, the legal provision, supporting documents and case law where relevant.
4. Computation: your computation of the correct liability, if any.
5. Interest and penalty: arguments on why penalty should not apply or should be at the reduced rate, and evidence of tax already paid.
6. Request for personal hearing.

Paying the tax with interest within the early window can significantly reduce or eliminate penalty in non-fraud cases. Discuss this option with your CA before replying.

A worked example of a mismatch reply

A Vadodara company receives DRC-01C for August. GSTR-3B ITC is ₹4,80,000 but GSTR-2B shows ₹3,60,000, a difference of ₹1,20,000. The reconciliation shows:

Reason	Amount
Invoices that appeared in June and July GSTR-2B but were claimed in August, after the goods were received	₹90,000
Invoice in August GSTR-2B kept aside because goods arrive in September	Minus ₹10,000
Credit claimed for invoices not appearing in any GSTR-2B	₹40,000
Total difference	₹1,20,000

Check: ₹90,000 minus ₹10,000 plus ₹40,000 = ₹1,20,000. The first item is a valid timing explanation: credit is claimed when both conditions, appearance in GSTR-2B and receipt of goods, are met, and the company can show the earlier GSTR-2B extracts and goods receipt notes. The second item reduces the gap, since credit appearing in August was deferred. The ₹40,000 claimed for invoices not in any GSTR-2B is not allowable; the company reverses it through DRC-03 with interest and explains the rest in Part B of DRC-01C with supporting extracts.

Writing a clear reply: structure that works

Officers handle many files. A reply that is easy to follow gets resolved faster. A practical structure for most notices:

1. Reference block: GSTIN, legal name, notice form, reference number, date and period.
2. Summary table: each discrepancy, the amount in the notice, your explanation in one line, and the amount you accept, if any.
3. Detailed explanation: one paragraph per discrepancy with the facts and the relevant rule.
4. Payment details: DRC-03 ARN, date and amount, for anything you have paid.
5. Annexures: numbered reconciliations, return extracts, invoice copies and ledgers, referred to in the explanation.
6. Closing request: that the proceedings be dropped, or that a personal hearing be granted.

Keep the language factual and polite, avoid long legal arguments for simple mismatches, and make sure every number in the reply ties to an annexure.

After the order: appeals

If a demand order is passed and you disagree, you can appeal to the Appellate Authority in APL-01 within three months of the order, after paying the admitted amount and a pre-deposit of 10% of the disputed tax (subject to caps). Further appeals lie to the GST Appellate Tribunal. Interest and penalty continue to be disputed in appeal, and recovery of the balance is stayed once the pre-deposit is made.

Mistakes to avoid

• Ignoring the notice or missing the deadline. Ex parte orders are common when no reply is filed.
• Replying by email or letter instead of on the portal in the prescribed form.
• Generic replies without reconciliations or documents.
• Paying amounts that are not actually due because it is simpler.
• Not asking for a personal hearing when a demand is proposed.
• Not keeping copies of everything filed.

Notice-readiness checklist

1. Monthly reconciliations of GSTR-1, GSTR-3B and GSTR-2B saved.
2. Annual reconciliation of books with GSTR-9 saved.
3. E-way bill data reconciled with sales.
4. Payment proofs for all challans and DRC-03 filings.
5. Portal notices tab checked weekly and email alerts monitored.
6. CA contact and authorisation ready for hearings.

Frequently Asked Questions

How do I check if a GST notice is genuine?

Check the Notices and Orders section on the GST portal, and verify the DIN of CBIC notices on the CBIC website. Do not pay against notices received only through unofficial channels.

What happens if I do not reply to a GST notice?

The officer can pass an order based on available information, often with full demand, interest and penalty. For mismatch intimations, the portal can block filing of subsequent returns.

Can I ask for more time to reply?

Yes. You can request an adjournment, usually through the portal or in writing. Adjournments are limited in number, so use them carefully.

Should I pay the tax before replying?

Pay amounts you agree are due, with interest, through DRC-03 before replying, because early payment can reduce penalty. Do not pay disputed amounts without advice.

Can I reply without a CA?

Simple mismatch intimations can often be handled by your accounts team with good reconciliations. Scrutiny and show cause notices benefit from professional help.
