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 ThreeB vs GSTR TwoB 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 One Delay)
Scenario: You purchased Rs. 10 Lakh goods from a registered supplier, but the supplier filed late GSTR One (or hasn't filed yet). Your GSTR TwoB 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 One filing. Taxpayer holds all original invoices and payment proof. Upon supplier's filing, the system will auto-populate GSTR TwoB. 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 ThreeB
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 One Form GST CRN. The demand notice appears to have been raised ignoring the credit note adjustment."
- Provide GSTR ThreeB 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 < Rs. 20 Lakh (for goods)
- Services: Unregistered if annual turnover < Rs. 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 One vs GSTR ThreeB Mismatch: Output tax declared in GSTR ThreeB does not match invoices filed in GSTR One (variance > 5%)
- GSTR ThreeB vs GSTR TwoB Variance: ITC claimed in GSTR ThreeB (Schedule 4B) exceeds what suppliers actually filed in GSTR One (GSTR TwoB 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 ThreeB
- Turnover / Taxability Misreporting: Declaring Rs. 50 Lakh turnover but GSTN data shows Rs. 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 Rs. 10 Lakh tax demand + interest can snowball to Rs. 14, Rs. 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
Real-World Case: Successful Notice Reply
Scenario: A retailer received a DRC-01 SCN for Rs. 25 Lakh tax demand claiming ITC fraud.
Officer's Allegation: GSTR TwoB showed Rs. 1.50 Crore ITC claimed, but only Rs. 1 Crore worth of GSTR One invoices matched. Gap of Rs. 50 Lakh ITC wrongfully claimed.
Retailer's Reply Structure:
- Preliminary Objection: "The notice cherry-picks 3 months (July, Sept 2025) when suppliers filed GSTR One late. Year-to-date, all suppliers have since filed; GSTR TwoB now matches GSTR One 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). Rs. 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.
