How to Reply to GST Notice: Step-by-Step Guide 2026

Receiving a GST notice from the tax department can be alarming. However, as someone who has helped businesses respond to over 2,000 GST notices in my 15+ years of practice, I can tell you this: a well-drafted response within the stipulated timeline resolves most cases favourably.

In this comprehensive guide, I will walk you through exactly how to reply to a GST notice -- from understanding the notice type to drafting your response with proper documentation. Whether you have received a scrutiny notice for GSTR-1 and GSTR-3B mismatches, a show cause notice under DRC-01, or a registration cancellation threat under REG-17, this guide covers the exact steps, sample reply formats, deadlines, and common mistakes to avoid.

What is a GST Notice?

A GST notice is an official communication issued by the GST department under various sections of the CGST Act, 2017. These notices are served through the GST portal, email, or physical delivery, requiring taxpayers to respond within specified timelines.

Under the GST regime, the department uses a standardised system of forms for issuing notices and receiving responses. Each form corresponds to a specific section of the CGST Act and triggers a defined response process. Understanding which form you have received is the first and most critical step in formulating your response.

All Major Types of GST Notices Explained

ASMT-10: Scrutiny Notice (Section 61)

This is the most common notice type issued to taxpayers. The GST officer issues ASMT-10 when they identify discrepancies during scrutiny of your returns. Common triggers include:

• Mismatch between GSTR-1 (outward supplies) and GSTR-3B (summary return) figures

• Mismatch between GSTR-2B (auto-populated ITC) and ITC claimed in GSTR-3B

• Unusually high ITC claims relative to output tax

• Discrepancies between GSTR-1 data and e-way bill data

• Inconsistencies flagged by the department's data analytics system

Response form: ASMT-11
Timeline: 30 days from the date of notice (extendable by an additional 30 days on request)
Key point: If your response is accepted, the officer drops the matter by issuing an order in ASMT-12. If not accepted, the matter may escalate to a demand proceeding under Section 73 or 74.

DRC-01: Show Cause Notice (Section 73/74)

DRC-01 is a formal show cause notice (SCN) issued when the department believes there is a tax shortfall. This is a more serious notice than ASMT-10 because it initiates a formal demand determination process.

• Section 73: Issued for non-fraud cases (inadvertent errors, miscalculations). The notice must be issued at least 3 months before the time limit for issuing the final order (which is 3 years from the due date of the annual return).

• Section 74: Issued for fraud, wilful misstatement, or suppression of facts. The notice must be issued at least 6 months before the time limit (which is 5 years from the due date of the annual return).

Response form: DRC-06
Timeline: 30 days from the date of notice
Key point: If you agree with the demand partially or fully, you can pay the admitted amount using DRC-03 before the SCN is adjudicated to reduce penalty exposure.

DRC-01A: Intimation of Tax Ascertained as Payable

Introduced to reduce litigation, DRC-01A is a pre-SCN communication. The officer intimates the taxpayer about the tax liability ascertained before issuing a formal show cause notice. This gives you an opportunity to pay the tax and close the matter without formal proceedings.

Response: DRC-01A Part B (either accepting liability and paying, or explaining why the demand is incorrect)
Timeline: As specified in the intimation (usually 15-30 days)
Key point: Paying the tax at this stage can help you avoid penalty and reduce interest liability. If you disagree, provide a detailed explanation -- the officer must consider it before proceeding to DRC-01.

DRC-03: Voluntary Payment Form

DRC-03 is not a notice but a form used by taxpayers to make voluntary payment of tax, interest, or penalty. It is relevant in the context of notices because:

• Paying via DRC-03 before the SCN is issued (under Section 73(5) or 74(5)) can eliminate or significantly reduce penalty.

• Under Section 73, if you pay the full tax and interest before the SCN, no penalty is levied and proceedings are concluded.

• Under Section 74, if you pay within 30 days of the SCN, penalty is reduced to 15% of the tax amount.

GSTR-1 and GSTR-3B Mismatch Notice

While not a formal statutory notice, the department frequently sends system-generated communications highlighting mismatches between GSTR-1 and GSTR-3B. These typically flag:

• Outward supply mismatch: Taxable value or tax amount reported in GSTR-1 differs from GSTR-3B for the same period.

• ITC mismatch: ITC claimed in GSTR-3B exceeds the eligible ITC as per GSTR-2B.

• Late fee or interest shortfall: Tax paid after the due date without corresponding interest.

These mismatches are common and often arise due to timing differences, amendments in subsequent returns, or data entry errors. Ignoring them, however, can lead to formal scrutiny proceedings.

REG-17: Show Cause for Registration Cancellation (Section 29)

Response form: REG-18
Timeline: 7 working days from the date of notice
Common triggers: Non-filing of returns for a continuous period of 6 months (regular taxpayer) or 3 consecutive quarters (composition taxpayer), or contravention of GST provisions.

Other Notable Notice Forms

Step-by-Step Guide to Reply to GST Notice

Step 1: Download and Read the Notice Carefully

Log in to the GST portal (gst.gov.in) and navigate to Services, then User Services, then View Additional Notices/Orders. Download the complete notice and read every paragraph carefully. Note down:

• Notice reference number (DIN -- Document Identification Number)

• Section under which notice is issued

• Specific allegations or discrepancies mentioned

• Documents demanded

• Response deadline

Important: Verify the DIN of the notice on the CBIC DIN verification portal (esanction.cbic.gov.in). Any notice without a valid DIN is deemed to have never been issued, as per CBIC Circular No. 122/41/2019-GST. This is a powerful technical defence that many taxpayers overlook.

Step 2: Identify the Notice Type and Relevant Section

Each notice type has specific response requirements:

Step 3: Gather Supporting Documents

Based on the notice allegations, compile a comprehensive document set. The specific documents depend on the notice type:

For GSTR-1/3B mismatch notices:

• GSTR-1 and GSTR-3B returns for the relevant period and the immediately preceding and following periods

• Reconciliation statement showing the source of mismatch (amendments, credit/debit notes, rounding differences)

• Tax invoices for disputed transactions

• GSTR-9 (annual return) and GSTR-9C (reconciliation statement) if filed

For ITC-related notices:

• GSTR-2A/2B for the relevant period

• Purchase register with invoice-wise details

• Supplier GSTIN verification and return filing status

• Bank statements showing payment to suppliers

• Delivery challans, goods receipt notes, or service completion certificates

• ITC reconciliation between books and GSTR-2B

For demand notices (DRC-01):

• All of the above, plus:

• Ledger accounts (cash ledger, credit ledger, liability ledger from the GST portal)

• Audited financial statements for the relevant year

• Any prior correspondence with the department on the same matter

• Legal opinions or precedent orders supporting your position

Step 4: Prepare Your Response

Structure your reply as follows:

1. Subject line: Include notice number, DIN, GSTIN, and section. Example: "Reply to Scrutiny Notice No. ZA1234567890 (DIN: 202526XXXXXXXX) u/s 61 of CGST Act, 2017 -- GSTIN 27AABCU9603R1ZM"

2. Acknowledgment: Acknowledge receipt of notice with the date you received it

3. Brief background: One paragraph about your business, registration details, and compliance history

4. Para-wise reply: Address each allegation point by point with specific facts, figures, and cross-references to supporting documents

5. Reconciliation tables: Where the notice involves numerical mismatches, include clear reconciliation tables

6. Legal grounds: Cite relevant sections, rules, circulars, and tribunal/court decisions supporting your position

7. Supporting evidence: Reference each attached document as a numbered Annexure

8. Conclusion: Clearly state whether you request closure of proceedings or a personal hearing

9. Undertaking: Declaration that the information provided is true and correct

Step 5: Submit Response on GST Portal

For online submission:

1. Login to GST portal with your credentials

2. Navigate to Services, then User Services, then View Additional Notices

3. Select the relevant notice and click "Reply"

4. Fill the appropriate response form (ASMT-11, DRC-06, REG-18, etc.)

5. Upload supporting documents (PDF format, maximum 5MB per file -- if your documents exceed this, split them into multiple PDFs named clearly as Annexure-A, Annexure-B, etc.)

6. Preview the complete response carefully before signing

7. Sign with DSC (Digital Signature Certificate) or EVC (Electronic Verification Code) and submit

8. Download the acknowledgment receipt with ARN (Application Reference Number) for your records

Pro tip: Always save a PDF copy of your complete submission (response + all attachments) before submitting. The GST portal occasionally has technical issues, and having an offline copy protects you if the portal-displayed version is incomplete.

Step 6: Follow Up and Track Status

After submission:

• Track status through Case Details on the GST portal (Services > User Services > My Applications > Case Details)

• Respond to any additional queries within 15 days of receipt

• Attend personal hearing if scheduled -- prepare a written submission to hand over during the hearing

• Keep copies of all communications in a dedicated file for each notice

• If no response is received from the officer within 30 days of your submission, follow up in writing requesting closure

Respected Sir/Madam,

With reference to the above-mentioned scrutiny notice received on [date of receipt], I, [Name], [Designation] of [Company Name], GSTIN [number], hereby submit my point-wise reply as under:

1. Allegation: Mismatch between GSTR-1 and GSTR-3B for the period [month/year] amounting to Rs. [amount]

Reply: The difference of Rs. [amount] between GSTR-1 and GSTR-3B is reconciled as follows:

(a) Credit note no. [XXX] dated [DD/MM/YYYY] for Rs. [amount] was reported in GSTR-1 of [month] but reflected in GSTR-3B of [subsequent month] due to the revision cycle. (Annexure-A: Copy of credit note and amended GSTR-3B)

Common Mistakes to Avoid

1. Missing the deadline: Non-response leads to ex-parte orders under Section 73(10). The officer can determine the tax liability based on available information without giving you further opportunity. Set reminders 7 days before the due date and begin preparation immediately upon receipt.

2. Generic responses: Avoid vague replies like "all records are maintained properly" or "we are in compliance with all GST provisions." Address each allegation with specific facts, figures, invoice numbers, and dates. The officer needs to see that you have engaged with the specific issues raised.

3. Incomplete documentation: Missing documents weaken your case significantly. If a document is not available (for example, a supplier's GSTR-1 filing status), state this explicitly and explain what alternative evidence you are providing instead.

4. Ignoring technical and procedural defects: Many notices contain procedural errors that can be valid grounds for challenging the notice itself. Common defects include:

   • Notice issued without a valid DIN (mandatory since October 2019)

   • Notice issued by an officer without jurisdiction over your registration

   • Time-barred notices (issued beyond the limitation period under Section 73 or 74)

   • Notice issued under Section 74 (fraud) without establishing the ingredient of fraud, wilful misstatement, or suppression

5. Not seeking adjournment when needed: If you genuinely need more time to compile documents or seek professional advice, file a written request for extension before the deadline expires. Under Section 61, the officer can grant an additional 30 days. For DRC-01, request adjournment of the personal hearing date.

6. Admitting liability without analysis: Some taxpayers, in an attempt to resolve matters quickly, admit tax liability and make payments without fully analysing whether the demand is correct. Once you pay via DRC-03 acknowledging liability, it becomes very difficult to challenge the demand later. Always analyse the notice thoroughly before making any payment.

7. Not maintaining a notice register: Businesses that receive multiple notices over time should maintain a register tracking each notice, its status, deadlines, and resolution. This prevents notices from falling through the cracks and helps identify patterns that may indicate systemic compliance issues.

8. Responding only on the portal without a physical copy: For high-value demands or Section 74 notices, it is advisable to also send a physical copy of your response by registered post or speed post to the jurisdictional officer, in addition to the online submission. This creates an additional paper trail.

Important Deadlines and Penalties

Reduced Penalty Benefits Under Section 73

The CGST Act provides strong incentives for early resolution:

• Before SCN issuance: If you identify the shortfall and pay tax + interest voluntarily using DRC-03 before any SCN is issued, no penalty is levied and the proceedings are deemed concluded under Section 73(5).

• Within 30 days of SCN: If you accept the demand and pay tax + interest + 10% penalty within 30 days of the SCN, proceedings are concluded under Section 73(8).

• Within 30 days of the order: If the order has been passed but you pay within 30 days, the penalty is limited to 10% of the tax amount.

When to Escalate: The Appellate Process

If the adjudicating officer passes an order that you disagree with after considering your reply, you have the following escalation options:

First Appeal: Appellate Authority (Section 107)

• Timeline: File within 3 months of the date of the order (extendable by 1 month at the discretion of the Appellate Authority)

• Pre-deposit: 10% of the disputed tax amount (capped at Rs. 25 crore for CGST and Rs. 25 crore for SGST)

• Form: APL-01 on the GST portal

• Outcome: The Appellate Authority can confirm, modify, or annul the order

Second Appeal: Appellate Tribunal (Section 112)

• Timeline: Within 3 months of the first appellate order

• Additional pre-deposit: 20% of the remaining disputed tax (over and above the 10% paid for the first appeal)

• Note: The GST Appellate Tribunal (GSTAT) has been constituted and is operational in several states as of 2026. For states where the bench is not yet operational, the limitation period for filing the second appeal has been extended.

High Court and Supreme Court

Questions of law can be taken to the High Court under Article 226 (writ jurisdiction) or Article 227 (supervisory jurisdiction). Appeals against Tribunal orders on substantial questions of law lie to the High Court under Section 117 and further to the Supreme Court under Section 118.

Role of a CA or Virtual CFO in GST Compliance

While small notices for minor mismatches can be handled internally by your accounts team, there are clear benefits to engaging a Chartered Accountant or Virtual CFO service for GST compliance management:

Proactive Compliance (Prevention)

• Monthly reconciliation: A Virtual CFO ensures GSTR-1, GSTR-3B, and books of accounts are reconciled every month, not just at year-end. This prevents mismatches from accumulating.

• ITC validation: Regular verification of supplier return filing status and GSTR-2B matching ensures you only claim eligible ITC.

• Return review before filing: A professional review before each GSTR-3B filing catches errors before they reach the department.

• Annual return preparation: GSTR-9 and GSTR-9C preparation by a qualified professional ensures consistency between monthly returns and annual filings.

Reactive Support (When Notices Arrive)

• Notice assessment: Determining the merit and risk level of each notice and prioritising responses accordingly.

• Technical defence: Identifying procedural defects, applicable exemptions, and favourable precedents that a non-specialist may miss.

• Representation: Appearing for personal hearings and presenting arguments effectively before the adjudicating officer.

• Appellate support: Drafting appeal memorandums and representing before the Appellate Authority or Tribunal when needed.

EaseUp's Virtual CFO services include dedicated GST compliance management, ensuring that your business stays on top of return filings, reconciliations, and notice responses without the overhead of a full-time tax team.

Frequently Asked Questions

1. Can I reply to a GST notice offline?

While online response through the GST portal is the preferred and faster method, you can submit a physical reply to the jurisdictional officer. However, ensure you get an acknowledgment with a date stamp and maintain proof of delivery (registered post AD or speed post). For ASMT-10 scrutiny notices, the portal-based response is strongly recommended because it creates a timestamped digital record. For DRC-01 show cause notices, it is advisable to submit both an online response and a physical copy for your protection.

2. What if I disagree with the final order after my notice response is rejected?

You can file an appeal before the Appellate Authority under Section 107 within 3 months of the order date. A pre-deposit of 10% of the disputed tax amount (capped at Rs. 25 crore CGST + Rs. 25 crore SGST) is required. The appeal is filed online through the GST portal in Form APL-01. Importantly, during the pendency of the appeal, the recovery of the balance demand is stayed. If the first appeal is also unfavourable, you can approach the GST Appellate Tribunal (GSTAT) under Section 112 with an additional pre-deposit of 20%.

3. I received a notice but the demand is clearly wrong due to a system error. What should I do?

System-generated notices sometimes contain errors -- for example, comparing data from different periods or double-counting transactions that were amended. In your reply, clearly demonstrate the system error with a detailed reconciliation. Include screenshots from the GST portal showing the correct data. If the mismatch is due to a known portal glitch (which the GST Council or GSTN has acknowledged through advisories), cite the relevant advisory. The officer is required to consider your response before passing any order.

4. Can I request a personal hearing for a GST notice?

Yes, under Section 75(4) of the CGST Act, the adjudicating authority must grant a personal hearing if requested, or if any adverse decision is being contemplated. Mention your request for personal hearing explicitly in your written response. Personal hearings are now commonly conducted via video conferencing in many jurisdictions, which saves travel time. During the hearing, carry a written submission summarising your key arguments, along with all supporting documents in an organised folder.

5. What is the penalty for not responding to a GST notice at all?

If you do not respond to a GST notice within the stipulated time, the officer can pass an ex-parte order (best judgment assessment) under Section 73(10) or 74(10) determining the tax liability based on available information. This typically results in the maximum possible demand being confirmed, along with full interest and penalty. For Section 73 cases, the penalty is 10% of tax or Rs. 10,000 (whichever is higher). For Section 74 cases, the penalty is equal to 100% of the tax amount. Additionally, you lose the opportunity to make favourable arguments. While you can still appeal the ex-parte order, the Appellate Authority will consider your non-response unfavourably, and you will need to deposit 10% of the demand as pre-deposit for the appeal.

When to Seek Professional Help

Consider engaging a tax professional when:

• The notice involves fraud allegations under Section 74

• The demand amount exceeds Rs. 10 lakh

• Multiple notices have been received simultaneously for different periods

• Search and seizure operations have been conducted at your premises

• Criminal prosecution is threatened under Section 132

• The notice involves complex issues such as place of supply determination, classification disputes, or valuation challenges

• You have received a notice for a period where your records are incomplete

• The response deadline is imminent and you have not yet begun preparation

Conclusion

Responding to a GST notice requires precision, proper documentation, and strict adherence to timelines. A structured approach -- understanding the notice type, gathering complete evidence, and drafting a detailed point-wise response -- significantly improves your chances of favourable resolution. Remember that most GST notices, particularly scrutiny notices under Section 61, are resolved at the first stage if the taxpayer provides a clear, well-documented explanation.

The key is to act promptly, respond specifically (not generically), and maintain complete records of all submissions and communications. For businesses that want to prevent notices rather than react to them, investing in regular GST reconciliation and professional compliance review is far more cost-effective than dealing with demands, penalties, and appeals after the fact.
