GST Notice Reply: How to Respond to Any GST Notice Online in India (2026)

A GST notice lands in your inbox and for most business owners the first reaction is panic. Heart rate up, calls to the accountant, frantic Google searches at midnight. I get it. In my experience working with small business owners across India, the notice itself is rarely the real problem. The real problem is not knowing what to do next, and doing nothing because of that uncertainty.

Here's the thing: most GST notices are routine. They don't mean your business is in trouble. They mean the system flagged something a mismatch, a late filing, a data gap and wants an explanation. Reply correctly and on time, and the matter closes. Ignore it, and a small issue becomes a very large one.

This guide covers everything you need the types of notices, the exact steps to file a GST notice reply online, formats for show cause notices under Section 73 and 74, the new Section 74A rules from FY 2024-25 onwards, and what happens if you miss the deadline. No jargon where plain language will do.

What Is a GST Notice and Why Did You Receive One?

A GST notice is a formal legal communication issued by the GST department under the CGST Act, 2017. It asks you to explain, pay, or provide documents in response to a discrepancy, non-filing, or compliance gap the system detected in your GSTIN. Most notices arise from automated return matching on the GSTN platform  not manual inspections.

The GST Network (GSTN) runs continuous automated checks. It matches your GSTR-3B with your GSTR-1, cross-checks your Input Tax Credit (ITC) claims against GSTR-2B, and compares your declared turnover with data from the Income Tax department. When a gap appears even a small one the system flags your GSTIN and a notice goes out.

What triggers these flags most often? Based on what I've seen across dozens of cases, the top reasons are:

• ITC claimed in GSTR-3B doesn't match the GSTR-2B the single most common trigger
• GSTR-1 or GSTR-3B filed after the due date for more than two consecutive months
• Turnover declared in GST returns doesn't align with your Income Tax Return figures
• Refund claims that look high relative to the tax paid in the same period
• Registration details that are outdated wrong address, inactive mobile number, unverified Aadhaar
• Inconsistencies between your e-way bill data and what's declared in returns

Worth knowing: a GST scrutiny notice doesn't automatically mean fraud or prosecution. Section 61 scrutiny notices (Form ASMT-10) are routine they ask for clarification, not confession. The tone of your reply and the evidence you attach matter far more than any alarm the notice creates.

A GST notice is a formal demand under the CGST Act, 2017 this is the legal standard across all 29 states and 8 union territories of India.

Types of GST Notices You Must Know Before Replying

GST notices come in several forms ASMT-10 (scrutiny), GSTR-3A (non-filing), REG-03 (registration clarification), REG-17 (cancellation), DRC-01 (show cause/demand), and DRC-07 (final demand order). Each has a different response form, deadline, and legal consequence. Knowing which type you've received is the first decision, not the last.

Do you know the difference between an ASMT-10 and a DRC-01? Most business owners don't and that's where expensive mistakes happen. Let me break each one down simply.

ASMT-10-Scrutiny Notice (Section 61)

This is a return scrutiny notice. The officer identified discrepancies in your filed returns — typically a gap between GSTR-1, GSTR-3B, and GSTR-2A or 2B. You must reply using Form ASMT-11 within 30 days of receiving the notice. The officer may extend this by up to 15 days at their discretion. This is your best and cheapest opportunity to close a matter — respond here with good documentation and most cases end without penalty.

GSTR-3A- Non-Filing Demand Notice (Rule 68)

Issued when you haven't filed your GSTR-1 or GSTR-3B. The notice demands that you file the pending returns within 15 days of receiving it. Don't ignore this one non-compliance leads to a best-judgment assessment under Section 62, meaning the officer estimates your tax liability and passes a demand order. The reply here is simply filing the overdue returns and paying any late fees and interest due.

REG-03-Registration Clarification Notice

Issued during your GST registration process when the officer needs more information or documents. Reply using Form REG-04 within 7 working days. If you're at the registration stage, this notice is actually quite standard see our GST Registration Documents Checklist for what's typically needed.

REG-17- Cancellation Notice

This one needs immediate attention. It means GST authorities are proposing to cancel your registration either because of complaints, non-filing, or address issues. Reply using Form REG-18 within 7 working days explaining why your registration should not be cancelled. Seven days goes fast. Don't sit on this.

DRC-01-Show Cause Notice (SCN) for Tax Demand

Issued under Section 73 (non-fraud cases) or Section 74 (fraud or suppression). This is the serious one. The department is proposing a tax demand with interest and penalty. You have 30 days to reply using Form DRC-06 for most SCN proceedings. Your reply must address every allegation point by point silence on any allegation is treated as acceptance under GST law.

DRC-07- Final Demand Order

This is what happens after an SCN if your reply was unsatisfactory or you didn't reply at all. It's a finalized demand order. At this stage, the path is appeal — not a fresh reply. Prevention is much easier than cure.

ADT-01-GST Audit Notice (Section 65)

Issued when your business is selected for a GST audit. You have 15 days to respond and cooperate. Keep your records organised invoices, reconciliations, payment proofs going back at least 5 years.

Section 73, Section 74, and the New Section 74A — What's the Difference?

Section 73 covers non-fraud tax demands genuine errors and omissions  with penalties capped at 10% of tax due (minimum Rs 10,000). Section 74 applies to fraud, suppression, or wilful misstatement penalty can reach 100% of tax due. Section 74A, effective from FY 2024-25, is a new unified provision with a 42-month notice window that replaces Sections 73 and 74 for newer financial years.

Here's what most guides won't tell you: which section your notice falls under changes everything the penalty amount, the evidence standard, and your legal options. A Section 73 matter is handled very differently from a Section 74 allegation.

GST Notice Under Section 73 (Non-Fraud Cases)

Section 73 is the "honest mistake" category. It applies when the department believes there's a short payment or wrong ITC claim but there's no allegation of fraud, wilful misstatement, or suppression. The department has 3 years from the due date of the annual return for the relevant financial year to issue this notice (for cases up to FY 2023-24).

The reply deadline is 30 days from the date of notice. Penalty is 10% of the tax due, subject to a minimum of Rs 10,000. Here's the good news for older cases: the government announced a conditional waiver of interest and penalty on Section 73 demands for FY 2017-18, 2018-19, and 2019-20 under Section 128A of the CGST Act provided the full tax is paid by the notified deadline. If you have old pending Section 73 matters, check this right now.

GST Notice Under Section 74 (Fraud Cases)

Section 74 is the harder path. It involves an allegation of fraud, suppression of facts, or wilful misstatement. The penalty here can reach 100% of the tax due and prosecution under Section 132 is possible in serious cases. The department gets 5 years (not 3) to issue a notice for these cases.

In my view, the single biggest mistake taxpayers make on Section 74 notices is trying to handle them without a Chartered Accountant or GST practitioner. The legal threshold for "fraud" is specific many notices use this section incorrectly, and a well-argued reply can get a matter reclassified to Section 73, slashing the penalty from 100% to 10%.

Section 74A- The New Unified Provision (From FY 2024-25)

This is the big change for 2026. Union Budget 2024 introduced Section 74A, which applies to demand proceedings for FY 2024-25 and beyond. It creates a single, unified notice framework replacing the old Section 73 and 74 structure for newer years. The notice period is now 42 months from the relevant financial year's return due date. The time limit for taxpayers to avail reduced penalty by paying tax plus interest has been extended from 30 days to 60 days under Section 74A.

(This 74A change is still being operationalised CBIC notifications will clarify the final implementation date, so confirm with your CA for the exact applicability timeline.)

How to Reply to a GST Notice Online—Step by Step

To file a GST notice reply online, log in at gst.gov.in, go to Services → User Services → View Notices and Orders (or View Additional Notices/Orders), find your notice, click Reply or Respond, fill in the response form, attach supporting documents, and submit. Save the acknowledgment receipt. Physical replies are not accepted for most notice types.

Can you actually do this yourself without a CA for simpler notices? Yes, in many cases. Here's the exact process as it works on the GST portal in 2026.

Step 1: Log in to the GST Portal
Visit gst.gov.in. Enter your GSTIN, username, password, and the captcha. Use the credentials for your authorised signatory if you're logging in on behalf of the business.

Step 2: Navigate to Notices and Orders
From the dashboard, click the Services tab. Select User Services from the dropdown. Choose View Notices and Orders or alternatively, View Additional Notices/Orders, depending on your notice type. Both paths exist on the portal (it's slightly confusing the portal has two different sections for different notice categories).

Step 3: Find Your Specific Notice
The system shows all notices issued to your GSTIN, usually for the past year. Click the Document hyperlink next to the relevant notice. Download it and read it fully understand the specific section invoked, the discrepancy alleged, and the response deadline stated.

Step 4: Click Reply or Respond
Scroll down past the notice details. There'll be a Reply or Submit Reply button the exact label varies slightly by notice type. Click it. The portal opens the appropriate response form (ASMT-11, REG-18, DRC-06, etc.).

Step 5: Draft Your Response
For ASMT-10 notices: you'll see options to either accept the discrepancy and pay voluntarily, or provide explanations and clarifications. For DRC-01 / SCN notices: you write a detailed explanation in the text box addressing each allegation. Reference the relevant GST sections, rules, or CBIC circulars where applicable. Be specific and factual avoid vague language like "there may have been a minor oversight."

Step 6: Attach Supporting Documents
Upload your supporting documents in PDF or JPG format. File size limits apply — check the portal's current upload limits. Common documents needed:

• GSTR-2A/2B vs GSTR-3B reconciliation statement

• Relevant sales and purchase invoices

• Bank statements for the disputed period

• Payment challans (DRC-03) if you're paying any admitted liability

• Previous correspondence with the GST department, if any

Step 7: Submit and Save Acknowledgment
Review everything before hitting Submit once submitted, replies generally can't be easily revised. After submission, download and save the acknowledgment receipt. This is your proof of compliance.

Step 8: Monitor the Portal for Follow-Up
The officer may issue further queries, schedule a personal hearing, or pass an order. Check the portal regularly replies and orders from the department also appear under View Notices and Orders.

GST Notice Reply Format-What Your Written Response Must Include

A proper GST notice reply format includes: the notice reference number and date, your GSTIN and business name, a point-by-point response to every allegation, references to the applicable CGST Act provisions or CBIC circulars, a list of attached documents, and a request for a personal hearing if the matter is complex. Every point in the notice must be addressed unanswered allegations are treated as admitted.

What should the actual written reply say? This is where most self-filed replies fall short-they're either too brief ("The discrepancy was a data entry error, please close the matter") or too vague to be defensible. The GST officer reviewing your reply is looking for a factual rebuttal tied to actual records.

What NOT to Write in Your GST Notice Reply

Don't be vague. "The ITC discrepancy was due to system errors" without any supporting reconciliation is the kind of reply that gets rejected. Don't admit to more than the notice asks — respond only to the specific allegations. Don't leave any allegation unanswered, even if you think it's obvious. And don't file a reply with attachments that don't directly address the allegations — irrelevant documents pad the reply but don't help it.

What Happens If You Ignore a GST Notice?

Ignoring a GST notice results in an ex-parte assessment order the officer decides your liability based only on available data, without your input. This is almost always worse than filing a reply. Consequences include automatic demand orders, penalties up to 100% of tax due (for fraud notices), bank account attachment under Section 79, suspension of GST registration, and blocking of e-way bill generation.

Let me be clear on this: there is no such thing as a "safe" non-response to a GST notice. Not a single type. The consequences escalate quickly and they're not reversible without legal proceedings.

If you don't respond to an ASMT-10 scrutiny notice, the officer can escalate to a DRC-01 show cause notice which carries higher penalties. If you don't respond to a DRC-01, the officer passes a DRC-07 demand order. From there, you're looking at an appeal, not a reply.

For Section 74 fraud notices specifically: ignoring the SCN means the department can impose penalties up to 100% of the tax due, plus interest, plus initiate prosecution under Section 132 of the CGST Act for wilful evasion. Banks accounts can be provisionally attached under Section 83. E-way bill generation can be blocked, which shuts down your supply chain immediately.

Missing a deadline isn't always fatal but acting quickly after a missed deadline matters. For some notice types, you can apply for restoration of proceedings if you had a valid documented reason. This requires additional effort and is subject to the officer's discretion. Don't count on it as your plan A.

GST Notice for ITC Mismatch–The Most Common Scenario in 2026

An ITC mismatch notice (usually an ASMT-10 under Section 61) is issued when the Input Tax Credit you claimed in GSTR-3B exceeds what's reflected in GSTR-2B based on your supplier's filings. To reply, prepare a GSTR-2B vs GSTR-3B reconciliation, identify the specific invoices causing the mismatch, and explain why the ITC claim is valid or reverse the excess claim and pay the difference.

The question I get asked more than any other from business owners is: "I got a notice saying my ITC doesn't match what do I do?" This is by far the most common notice type in 2026, and the good news is it's usually resolvable with proper documentation.

The ITC mismatch happens because the GST system runs an automated reconciliation between your GSTR-3B (where you declare ITC claimed) and the GSTR-2B (which reflects ITC available based on your suppliers' filed GSTR-1 data). If your supplier filed GSTR-1 late or didn't file it at all  your ITC won't appear in GSTR-2B even if the transaction is genuine.

How to Handle an ITC Mismatch Reply

First, download your GSTR-2B for the disputed period and compare it line by line against your purchase register. Tools like Tally Prime, Zoho Books, and the GSTN offline utility all have reconciliation features that speed this up significantly.

Then, for every mismatched invoice, categorise it into one of three buckets: (1) the supplier has since filed and the ITC now appears in a later GSTR-2B attach proof; (2) the supplier hasn't filed but the transaction is genuine you may need to follow up with the supplier or reverse the ITC for now; (3) the ITC was claimed in error acknowledge, reverse, and pay with interest.

In my experience reviewing reconciliation cases, the most defensible replies are the ones that go invoice-by-invoice not the ones that give a general explanation. The more specific your documentation, the faster the matter closes.

GST DRC-01 Reply-Handling a Show Cause Notice for Tax Demand

A DRC-01 is a formal show cause notice proposing a tax demand with interest and penalty. Reply using Form DRC-06 within 30 days. Address every allegation, cite applicable sections and CBIC circulars, attach a reconciliation and relevant invoices, and if you partially agree consider paying the admitted amount with interest under DRC-03 to reduce the penalty exposure under Section 73(5) or 74(5).

A DRC-01 is where professional help genuinely pays for itself. This isn't bureaucratic caution  it's practical advice from someone who has seen self-filed DRC-01 replies go sideways because the person addressed the wrong allegation or used language that implied admission of fault.

The DRC-06 reply form on the GST portal has two main paths: you either contest the demand fully, or you partially agree and propose to pay the admitted portion. If you agree fully and pay within 30 days of the SCN, the penalty under Section 73 is 10%. Wait until after the order, and it could be 15%. The financial incentive to reply early is real.

For Section 74 SCNs (fraud allegations): challenge the classification itself if the underlying transaction is genuine. Many Section 74 notices are issued on automated risk flags not after actual investigation. A well-argued reply showing the transaction records, tax payment trail, and absence of suppression can get the matter reclassified or dropped entirely.

The CBIC's own circulars particularly Circular No. 31/05/2018 and subsequent updates on ITC reconciliation are useful to cite in your reply. Tally Solutions and ClearTax both publish updated guidance on CBIC circulars that practitioners use as reference.

Frequently Asked Questions 

What is the time limit to reply to a GST notice?

The reply deadline depends on the notice type. ASMT-10 scrutiny notices allow 30 days, with a possible 15-day extension at the officer's discretion. GSTR-3A non-filing notices require a response within 15 days. REG-17 cancellation notices and REG-03 registration notices both require a reply within 7 working days. DRC-01 show cause notices allow 30 days under Section 73 and 74, extended to 60 days under the new Section 74A framework.

Can I reply to a GST notice myself without a CA?

For straightforward notices like an ASMT-10 with a clear ITC reconciliation or a GSTR-3A requiring you to file pending returns a business owner can file the reply directly on the GST portal. For DRC-01 show cause notices, especially those under Section 74 involving fraud allegations or large demand amounts, engaging a Chartered Accountant or GST practitioner is strongly advisable. The cost of professional help is almost always less than a poorly-filed reply.

What documents are needed for a GST notice reply?

The exact documents depend on the notice type, but standard supporting documents include: a GSTR-2B vs GSTR-3B reconciliation statement for the disputed period, relevant purchase and sales invoices, payment challans (DRC-03) if you're paying an admitted liability, bank statements for the period in question, and any prior correspondence with the GST department. Upload these in PDF or JPG format through the portal's document attachment section.

What happens if I miss the GST notice reply deadline?

Missing a GST notice deadline is serious but not always fatal if you act immediately. For some notice types, you can apply for restoration of proceedings by showing a valid reason for the delay this is at the officer's discretion. If no reply and no application is filed, the officer may pass an ex-parte demand order or cancel your GST registration. Recovery proceedings including bank account attachment can follow. Act within days of a missed deadline, not weeks.

How do I find GST notices on the GST portal?

Log in to gst.gov.in using your GSTIN credentials. Go to Services → User Services → View Notices and Orders. For certain notice categories, navigate instead to Services → User Services → View Additional Notices/Orders. The portal shows all notices issued to your GSTIN, usually covering the past year. Click the Document link next to a notice to download it. The Reply button appears on the notice detail page when a response is open and pending.

Don't Let a GST Notice Sit Unanswered

A GST notice is not a verdict  it's a question. The three things worth remembering: identify the notice type and its exact deadline before doing anything else; build your reply around documented evidence, not explanations; and address every point in the notice, not just the ones you're confident about. Miss any of these and a manageable situation gets harder.

The gst notice reply process on the portal is straightforward once you know which notice type you're dealing with and which form to use. Section 73 matters can often be closed quickly with a good reconciliation. DRC-01 show cause notices especially Section 74 allegations deserve professional review. Section 74A, effective for FY 2024-25 onwards, changes the timelines and penalty structure in ways that make early action even more valuable.

You know your business. You know the transactions. What you need is to translate that knowledge into the right format, filed in the right place, before the clock runs out. That's the whole game. The notice isn't the problem the silence is.
