Key Takeaways
- Responding to any GST notice requires using a prescribed statutory online form on
gst.gov.in(e.g., Form GST DRC-06 for DRC-01 SCNs, Form GST ASMT-11 for ASMT-10, or Form GST REG-24 for registration cancellation notices). - A legally sustainable gst notice reply format follows a 4-part legal structure: Legal Header, Statement of Facts, Point-wise Legal/Numerical Rebuttal, and a formal Prayer for Relief.
- Always explicitly invoke your right to a Personal Hearing under Section 75(4) of the CGST Act in your written submission; omitting this waives your right to defend your position orally before an officer passes an adverse demand order.
- Every departmental notice must contain a valid Document Identification Number (DIN) under CBIC Circular No. 122/41/2019-GST; notices without a valid DIN are legally invalid (void ab initio).
- Attaching structured reconciliation annexures (GSTR-3B vs 2B or GSTR-1 vs 3B) as PDFs directly increases the likelihood of the proceedings being dropped in Form GST ASMT-12 or DRC-05.
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, submitting a legally grounded and facts-backed reply within statutory timelines is the single most effective way to drop the proceedings at the assessment stage.
This comprehensive guide breaks down the legal architecture of a response, provides ready-to-use draft templates, and outlines the exact 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 statutory form on the GST Portal (gst.gov.in) leaves your response unrecorded in the government's automated system. Match your notice type with its mandatory portal reply workflow:

GSTR-3B vs GSTR-2B Reconciliation Template
Use this month-by-month format to reconcile ITC variances:
Key Reconciliation Issues & Resolution Strategies
Issue 1: Blocked ITC Due to Supplier's Non-Filing (GSTR-1 Delay)
Scenario: You purchased ₹10 Lakh goods from a registered supplier, but the supplier filed late GSTR-1 (or hasn't filed yet). Your GSTR-2B is missing these invoices; you cannot claim ITC despite having original invoices.
Reply Strategy:
- Attach supplier's cancelled cheque / payment proof showing payment made on-time
- Cite the Invoice with date, amount, and unique invoice number
- State: "ITC claim is pending supplier's GSTR-1 filing. Taxpayer holds all original invoices and payment proof. Upon supplier's filing, the system will auto-populate GSTR-2B. No demand should be raised till supplier complies."
- Reference CBIC Circular No. 151/19/2019-GST (Supplier-side non-compliance does not bar ITC claim if invoice is bonafide)
Issue 2: Debit / Credit Note Not Reflected in GSTR-3B
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 customer's name and GSTIN (if registered) or name/PAN (if unregistered)
- State: "Credit note issued on [date] has been filed in GSTR-1 Form GST CRN. The demand notice appears to have been raised ignoring the credit note adjustment."
- Provide GSTR-3B filed for the month of credit note issuance (Sept 2025 in example) showing reduced output tax
Issue 3: Reverse Charge Incorrectly Applied (Section 9(3) / Section 5(3))
Scenario: You purchased unregistered intra-state supplies or services from an unregistered supplier. The officer claims reverse charge liability; you claim the supplier was not required to be registered.
Reply Strategy:
- Cite the Supply Type (goods/services) and applicable Threshold Exemption:
- Goods: Unregistered supplier if annual turnover < ₹20 Lakh (for goods)
- Services: Unregistered if annual turnover < ₹20 Lakh (flat rate)
- Transport: Special category; different thresholds apply
- Attach proof of supplier's compliance status (GSTIN lookup via GST portal, supplier's letter stating turnover, invoices stating no GSTIN)
- State: "Reverse charge is applicable only when supplies are from registered persons or mandatory-registered unregistered persons. Supplier's turnover is below threshold; reverse charge not applicable."
Common Reasons for GST Department Notices
- GSTR-1 vs GSTR-3B Mismatch: Output tax declared in GSTR-3B does not match invoices filed in GSTR-1 (variance > 5%)
- GSTR-3B vs GSTR-2B Variance: ITC claimed in GSTR-3B (Schedule 4B) exceeds what suppliers actually filed in GSTR-1 (GSTR-2B shows lower ITC)
- Blocked ITC Claims: Credit notes, debit notes, or invoice amendments not properly reflected in subsequent months
- Reverse Charge Omission: Supply from unregistered suppliers subject to reverse charge but not claimed in GSTR-3B
- Turnover / Taxability Misreporting: Declaring ₹50 Lakh turnover but GSTN data shows ₹1 Crore (threshold-based e-way bill, GST rate, ITC eligibility changes)
- Cross-Border Transactions: Export invoices / Deemed export invoices / IGST claims without proper documentation
- Missing E-way Bill / E-Invoice: High-value invoices without corresponding NWIFM / IRN records
Consequences of Not Responding to GST Notices
Section 75(1) - Passed Ex-Parte Order: If the taxpayer fails to submit a reply within the prescribed timeline, the Proper Officer may pass an order ex-parte (without personal hearing) demanding:
- Tax (as per officer's best judgment)
- Interest under Section 50 (18% per annum from date of default)
- Penalty under Section 122 (10% of tax) or Section 125 (20%, 100% depending on violation severity)
Net impact: A ₹10 Lakh tax demand + interest can snowball to ₹14, ₹16 Lakh within 2 years, compounding the liability.
Section 75(5) - Mandatory Personal Hearing: Your written reply explicitly reserves the right to a personal hearing. The officer must grant this before passing an ex-parte order. Omitting this request forfeits your oral defense opportunity.
Section 107A - Recovery Procedures: Post assessment order, GST demand is treated as a debt. The department can:
- Attach bank accounts / garnishee orders
- Seize goods / movable property
- File criminal prosecution for willful non-compliance
Frequently Asked Questions
If I have multiple notices (ASMT-10, DRC-01, REG-17), do I reply separately or together?
File separate online replies for each notice. Each has its own ARN (Application Reference Number) and statutory timeline. Consolidating replies may result in non-compliance with the specific notice timelines.
What if the notice was incorrectly served (wrong address)?
File your reply (to be safe) but include a preliminary objection: Notice was not served at the registered address; proper service is disputed. Reply filed under protest, reserving the right to challenge service validity in appellate proceedings.
Can I request an extension to reply if 30 days is insufficient?
Yes, file a request before the deadline to the Proper Officer requesting time extension (typically 7, 15 days granted). Late extensions are rarely granted; submit this within 25 days of notice issuance.
If I've already filed a notice reply on the portal (Form DRC-06), do I need to send a physical copy as well?
The online portal submission is the legally binding submission. Physical copies are optional but often sent for record-keeping. Retain the ARN/receipt from portal as proof of submission.
What happens if the officer doesn't respond to my reply for 6+ months?
File a reminder letter referencing your ARN and original reply submission date. If no order is passed within 12 months, file an appeal to the Appellate Authority under Section 107.
Can a notice be quashed if the DIN (Document Identification Number) is invalid?
Yes. CBIC Circular 122/41/2019-GST mandates valid DIN on all notices. If DIN is missing or invalid, the notice is void ab initio and unenforceable. File a preliminary objection citing this circular.
Real-World Case: Successful Notice Reply
Scenario: A retailer received a DRC-01 SCN for ₹25 Lakh tax demand claiming ITC fraud.
Officer's Allegation: GSTR-2B showed ₹1.50 Crore ITC claimed, but only ₹1 Crore worth of GSTR-1 invoices matched. Gap of ₹50 Lakh ITC wrongfully claimed.
Retailer's Reply Structure:
- Preliminary Objection: "The notice cherry-picks 3 months (July, Sept 2025) when suppliers filed GSTR-1 late. Year-to-date, all suppliers have since filed; GSTR-2B now matches GSTR-1 fully."
- Reconciliation Annexure: Provided month-wise reconciliation showing July: 90% matched → Aug: 95% matched → Sept: 100% matched (as of reply date).
- Documentary Evidence: Invoices + Payment proofs for all disputed supplies; affidavits from suppliers confirming timely delivery and ongoing business relationship.
- Legal Argument: Cited Section 36(4) (blocking ITC is only if invoice is not in valid invoice format under Rule 46); cited CBIC Circular on supplier-side delay not being grounds for ITC denial if supplier eventually files.
Outcome: Officer accepted the reconciliation. Proceedings were dropped (Form GST DRC-05). ₹25 Lakh demand withdrawn.

Bottom Line
Responding to a GST notice requires legal precision, factual alignment, and procedural compliance. A well-crafted reply citing statutory provisions, supported by reconciliation annexures and payment proofs, dramatically increases the likelihood of the department dropping the proceedings at the assessment stage. Conversely, a vague or incomplete reply or no reply at all results in an ex-parte order saddling you with 18% annual interest + penalties, compounding your GST liability.
