Receiving an official inquiry or Show Cause Notice (SCN) from the GST Department can be overwhelming for business owners. Whether the officer is questioning Input Tax Credit (ITC) variances, turnover mismatches, or unfiled returns, a reply that is grounded in the law, backed by documents and filed within the time allowed is the most effective way to get the proceedings dropped at the assessment stage.
This guide breaks down the structure of a response, gives you a draft framework, and outlines the steps to submit your response on the portal.
Statutory Notice Types & Mandatory Online Reply Forms
Filing a physical letter at the tax office without submitting the prescribed form on the GST Portal (gst.gov.in) leaves your response unrecorded on the portal. Match your notice type with its reply form:
| Notice (form) | Legal basis | Reply form on the portal | Time to reply |
|---|---|---|---|
| Scrutiny of returns (ASMT-10) | Section 61, Rule 99 | ASMT-11 | Within the time stated in the notice, not more than 30 days from service, or any further period the officer allows |
| Pre-SCN intimation (DRC-01A) | Rule 142(1A) (optional for the officer) | Part B of DRC-01A (pay any admitted amount through DRC-03) | By the date given in the intimation; the rule fixes no period |
| Show cause notice (DRC-01) | Section 73 or 74 (up to FY 2023-24), Section 74A (FY 2024-25 onwards) | DRC-06 | Within the period stated in the SCN |
| Registration cancellation SCN (REG-17) | Section 29, Rule 22 | REG-18 | 7 working days from service |
| Clarification during registration (REG-03) | Rule 9 | REG-04 | 7 working days from receipt |
Always file through the portal form so that an Application Reference Number (ARN) is generated. If the proceedings under a REG-17 are dropped, the officer issues REG-20. For the GSTR-1 vs GSTR-3B and ITC difference intimations (DRC-01B and DRC-01C), see our DRC-01B and DRC-01C reply guide.
Time Limits the Officer Must Follow
A reply is also your chance to check whether the notice itself is within time.
| Provision | Applies to | SCN deadline | Order deadline |
|---|---|---|---|
| Section 73 (no fraud) | FY 2017-18 to FY 2023-24 | At least 3 months before the order deadline | 3 years from the due date of the annual return for that FY (or from the date of erroneous refund) |
| Section 74 (fraud, suppression) | FY 2017-18 to FY 2023-24 | Longer limits apply; check Section 74(2) and 74(10) | Check Section 74(10) |
| Section 74A (all cases) | FY 2024-25 onwards | 42 months from the due date of the annual return for that FY | 12 months from the date of the SCN, extendable by up to 6 months |
If the notice or the order falls outside these limits, raise it as the first preliminary objection.

GSTR-3B vs GSTR-2B Reconciliation Template
Use this month-by-month format to explain ITC variances. The figures are an illustration only.
| Tax period | ITC claimed in GSTR-3B Table 4(A) (Rs) | ITC shown in GSTR-2B (Rs) | Difference (Rs) | Explanation and annexure |
|---|---|---|---|---|
| July 2025 | 50,000 | 48,000 | 2,000 | 2 invoices reported late by supplier; they appear in August 2025 GSTR-2B (Annexure A1) |
| August 2025 | 55,000 | 57,000 | -2,000 | Includes the 2 late invoices above; ITC on them claimed only once (Annexure A2) |
| September 2025 | 60,000 | 60,000 | 0 | Fully matched |
Match the totals for the year against GSTR-9 as well, if you filed one.
Key Reconciliation Issues & Resolution Strategies
Issue 1: ITC Questioned Because the Supplier Filed GSTR-1 Late
Scenario: You purchased Rs. 10 Lakh goods from a registered supplier, but the supplier filed GSTR-1 late. The invoices were missing from your GSTR-2B for the month of purchase.
Reply Strategy:
- Since 1 January 2022, Section 16(2)(aa) allows ITC only on invoices that appear in your GSTR-2B. Show the GSTR-2B of the later period in which the invoices appeared and your ITC claim in that period
- Confirm the claim was made within the Section 16(4) time limit (30 November after the end of the FY, or the date of filing the annual return, whichever is earlier)
- Attach the invoices, payment proof and proof of receipt of goods (Section 16(2)(b))
- If ITC was claimed before the invoice appeared in GSTR-2B, admit the timing difference and show that it was later matched; interest under Section 50(3) at 18% may still apply if the excess credit was utilised
Issue 2: Credit Note Not Considered in the Notice
Scenario: You issued a credit note in September 2025 for goods returned by a customer, reducing output tax. But the notice assumes full tax on the original invoice.
Reply Strategy:
- Attach both the original invoice and the credit note (serial number, date, amount)
- Include the customer's name and GSTIN (if registered)
- State: "Credit note issued on [date] has been reported in GSTR-1 for [month]. The demand appears to have been raised without considering this credit note."
- Provide the GSTR-3B for the month in which the credit note was reported, showing the reduced output tax
- Show that the credit note was issued within the Section 34(2) time limit and, for B2B customers, that the customer has reversed the matching ITC
Issue 3: Reverse Charge Wrongly Applied (Section 9(3) / 9(4) CGST, Section 5(3) / 5(4) IGST)
Scenario: You bought goods or services from an unregistered supplier. The officer says you should have paid tax under reverse charge.
Reply Strategy:
- Reverse charge under Section 9(3) applies only to goods and services specifically notified by the government, whether the supplier is registered or not
- Reverse charge under Section 9(4) on purchases from unregistered suppliers applies only to notified classes of registered persons, such as certain purchases by real estate promoters. Ordinary purchases from unregistered suppliers do not attract reverse charge
- Show that the purchase is not covered by any reverse charge notification, with the invoice or bill describing what was bought
- The supplier's turnover being below the registration threshold is not by itself a defence; the question is only whether the supply is notified for reverse charge
Common Reasons for GST Department Notices
- GSTR-1 vs GSTR-3B Mismatch: Output tax declared in GSTR-3B is lower than the tax on invoices reported in GSTR-1
- GSTR-3B vs GSTR-2B Variance: ITC claimed in GSTR-3B Table 4 is higher than the ITC shown in GSTR-2B
- Credit and debit notes: Credit notes, debit notes or invoice amendments not reflected correctly in later returns
- Reverse Charge Omission: Tax on notified reverse charge supplies not paid in GSTR-3B
- Turnover Misreporting: Turnover in GST returns does not match income-tax returns, e-way bills or e-invoices
- Cross-Border Transactions: Export, deemed export or IGST refund claims without proper documentation
- Missing E-way Bill / E-Invoice: Invoices without matching e-way bill or IRN records where these were required
Consequences of Not Responding to GST Notices
Order without your reply: Under Section 73(9) (and the matching provisions of Sections 74 and 74A), the officer decides the demand after considering your representation, if any. If you do not reply, the order is passed on the material the officer has, and it can confirm:
- Tax proposed in the notice
- Interest under Section 50 at 18% per annum (simple interest) from the day after the due date until payment
- Penalty: in non-fraud cases 10% of tax or Rs. 10,000, whichever is higher (Section 73(9), Section 74A); in fraud or suppression cases, penalty equal to the tax (Section 74A)
Net impact (illustration): A Rs. 10 Lakh tax demand for a non-fraud case, paid 2 years late, carries interest of about Rs. 3.6 Lakh (10 Lakh x 18% x 2 years) and a penalty of Rs. 1 Lakh, a total of about Rs. 14.6 Lakh.
Paying early reduces penalty: Under Section 73(8), no penalty is payable if tax and interest are paid within 30 days of the SCN. Under Section 74A, the window is 60 days for non-fraud cases (no penalty), and fraud cases can close by paying tax, interest and 25% penalty within 60 days of the SCN.
Personal hearing (Section 75(4) and 75(5)): The officer must grant a personal hearing if you request it in writing or if an order adverse to you is contemplated. Ask for it clearly in your reply. The officer can grant adjournments, but not more than three times.
Recovery after the order (Sections 78 and 79): An unpaid demand under a confirmed order can be recovered. The department can, among other steps:
- Recover the amount from money it owes you, such as refunds
- Send notices to your bank or debtors to pay the amount directly to the government
- Detain and sell goods or other property
Appeal: An order can be appealed to the Appellate Authority in Form APL-01 within 3 months from the date it is communicated (Section 107(1)). A pre-deposit of 10% of the tax in dispute, subject to a maximum of Rs. 20 crore, is required with the appeal (Section 107(6)), apart from any amount you admit. A further appeal lies to the GST Appellate Tribunal (GSTAT), with an additional pre-deposit under Section 112(8).

Bottom Line
Responding to a GST notice requires legal precision, factual alignment, and procedural compliance. A clear reply that cites the law and is backed by reconciliation annexures and payment proof gives the best chance of the department dropping the proceedings. A vague reply, or no reply at all, can lead to an order confirming tax, 18% interest and penalty.
