GST Notice: Types, How to Read Them, and How to Respond

A GST notice is not a foregone conclusion of wrongdoing; it is often an automated flag triggered by a data mismatch between returns or an inconsistency in ITC claims, particularly ITC mismatches that are the most common notice trigger. The GSTN system compares GSTR-1 data from suppliers with GSTR-2B data auto-populated for buyers, and any gap above a threshold can generate a notice. Understanding the type of notice, the specific provision invoked, and the appropriate response format is the first step in resolving the matter without escalation to demand, adjudication, and potential litigation. You can reach the GST Council official portal through this.

What Triggers a GST Notice

GST notices arise from either automated system flags or officer-initiated proceedings. The primary triggers:

Automated system flags (GSTN analytics):

• Turnover declared in GSTR-1 differs significantly from GSTR-3B for the same period
• ITC claimed in GSTR-3B exceeds GSTR-2B entitlement by a material amount
• E-way bill generation is inconsistent with the declared turnover
• Returns filed but tax not paid within the interest-free window
• Suppliers flagged as suspicious (GSTN risk score) appearing in a taxpayer’s ITC chain

Officer-initiated proceedings:

• Post-audit findings of short payment or excess ITC
• Intelligence from DGGI or other enforcement agencies
• Cross-departmental triggers (Income Tax, Customs, Enforcement Directorate)
• Informant inputs or third-party complaints

Sector-specific campaigns:

The GST Council periodically directs anti-evasion drives in specific sectors (construction, steel trading, gems and jewellery). Businesses in these sectors may receive notices as part of a sector-wide campaign even without specific individual flags.

Types of GST Notices Under the GST Act

Scrutiny Notice (Section 61)

The most common notice type. Issued when there is an apparent inconsistency in a filed return, often arising from GSTR-2B reconciliation gaps that invite scrutiny. The officer is not alleging fraud; they are seeking an explanation for a specific discrepancy.

Typical triggers: GSTR-1 vs GSTR-3B turnover mismatch, ITC claimed vs GSTR-2B mismatch, zero-rated claims without corresponding exports.

Response: The taxpayer must reply within 30 days (or such period as specified). If satisfied, the officer closes the case. If not satisfied, they may initiate an audit under Section 65 or a determination proceeding.

Audit Notice (Section 65)

Issued at least 15 working days before a departmental audit begins. To understand how a GST audit escalates from a notice and what to expect during the records examination, refer to our full audit guide.

Show Cause Notice, Tax Underpayment (Section 73 or 74)

Section 73: For cases not involving fraud, wilful misstatement, or suppression. The officer believes tax has not been paid, short paid, or ITC has been wrongly availed.

Section 74: For cases involving fraud, wilful misstatement, or suppression of facts. The penalty exposure is significantly higher (100% of tax vs 10–15% under Section 73).

Time limits for issuing SCN:

• Section 73: Within 3 years from the due date of the annual return for the relevant period
• Section 74: Within 5 years from the due date of the annual return for the relevant period

Notice for Non-Filing (Section 46)

Issued to taxpayers who have not filed a return by the due date. This is largely automated; the portal generates the notice after a specified number of days of non-filing. The taxpayer must file the pending return within 15 days of the notice.

Notice for Recovery (Section 79)

Issued when a taxpayer has an outstanding confirmed demand (from an order) and has not paid. Allows the officer to recover from bank accounts, debtors, or attached property.

How to Read a GST Notice: Key Sections

When a GST notice is received (either on the portal under the “Notices” section or physically), examine these elements first:

1. Section invoked: Identifies the legal basis. Section 61 = scrutiny, Section 65 = audit notice, Section 73/74 = demand, Section 46 = return default. The section determines the response procedure and stakes.

2. Period covered: Which financial year and which months are under examination. This defines the scope of records you need to gather.

3. Specific discrepancy identified: Most notices list the precise mismatch, e.g., “ITC of ₹X claimed in GSTR-3B for June 2025 exceeds GSTR-2B entitlement by ₹Y.” This is the specific issue to address.

4. Response deadline: The number of days from the date of notice. Missing this deadline without seeking an extension can have serious consequences; it may be treated as acceptance of the discrepancy.

5. Designated officer and DIN: The Document Identification Number (DIN) on the notice confirms it is a valid, officially issued notice. All GST notices since November 2019 must carry a system-generated DIN. A notice without a DIN can be challenged as invalid.

Response Deadlines for GST Notices

Notice Type	Response Deadline
Section 61 (Scrutiny)	30 days from issue date (extendable)
Section 65 (Audit)	15 working days before audit begins (not a response; preparation period)
Section 73 SCN	7 days to respond with a payment plan or objection
Section 74 SCN	30 days (for voluntary payment with reduced penalty); officer passes order within 3 months
Section 46 (Non-filing)	15 days to file the pending return
Section 79 (Recovery)	7 days to respond with payment plan or objection

Requesting extension: Applications for time extension must be submitted to the jurisdictional officer in writing before the deadline expires. The officer has discretion to grant extensions for legitimate reasons.

How to Respond to a GST Scrutiny Notice

A Section 61 scrutiny response is a factual, document-backed explanation, based on the GST return filings that officers check against your notice. The response format depends on the discrepancy:

Turnover mismatch (GSTR-1 vs GSTR-3B):

Provide a table showing the reconciliation, identifying whether the mismatch is due to timing (invoice filed in a different period), amendments, credit notes, or a genuine error. Attach the relevant invoices and return excerpts.

ITC excess claim:

If the ITC claimed exceeds GSTR-2B, either: (a) provide evidence that the supplier has since filed (late filing), (b) show that the ITC was provisionally claimed within the permitted 5% buffer, or (c) acknowledge the excess and reverse it with interest payment via DRC-03.

Missing return:

If the notice is for non-filing, file the pending return immediately (within 15 days). The notice is resolved automatically once the return is filed.

Key principle: Responses must be factual and supported by documentation. Unsupported narrative responses invite further scrutiny. If the response reveals additional liability, voluntarily disclose and pay it, the penalty for voluntary pre-SCN payment is significantly lower.

GST Demand Notices and Adjudication Process

When a Section 73 or 74 SCN is issued, the adjudication process follows a structured timeline:

Stage 1: SCN issuance, Officer sends notice detailing alleged tax short-payment or wrong ITC. Note that the annual return that is most commonly the subject of scrutiny notices is GSTR-9 — discrepancies between GSTR-9 declared figures and monthly returns are a frequent SCN trigger.

Stage 2: Personal hearing, the taxpayer has the right to request a personal hearing before the adjudicating officer. This is a critical opportunity to present evidence and context before the order is passed.

Stage 3: Adjudication order, the officer passes the order determining tax, interest, and penalty. The taxpayer receives the order.

Stage 4: Appeal. If the taxpayer disagrees with the order, the appeal hierarchy is: Appellate Authority (within 3 months) → Appellate Tribunal (within 3 months of appellate order) → High Court → Supreme Court.

Voluntary payment window: Under Section 73, if the taxpayer pays the full demand (tax + interest) before or within 30 days of the SCN, the penalty is reduced to 10% of the tax (minimum ₹10,000). Under Section 74 (fraud), the penalty reduction for pre-SCN payment is more limited.

GST Notice Data as a Credit Risk Signal

For lenders assessing a business through GST data, the presence of outstanding notices or demands is a significant risk indicator, particularly for loan tenures that extend into periods when demand enforcement could become active.

A business with:

• Multiple Section 73/74 demands under appeal or contested
• Outstanding recovery notices (Section 79)
• A history of Section 61 scrutiny notices indicating persistent return inconsistencies

…presents a higher credit risk than a business with a clean notice history. The contingent liability from contested demands can materially affect the borrower’s effective net worth and debt service capacity.

Lenders conducting GST-based due diligence typically request a self-declaration of outstanding notices and cross-verify through the portal or API access, where available.

Key Takeaways

• GST notices range from automated scrutiny flags (Section 61) to fraud-based demand notices (Section 74); the section invoked determines the response stakes
• Every valid GST notice must carry a Document Identification Number (DIN); notices without DINs are challengeable as invalid
• Response deadlines are strictly enforced; missing a deadline is treated as a default. Seek extension if needed, before the deadline expires
• Voluntary payment of identified shortfall before SCN issuance (under Section 73) reduces penalty to 10% vs 100% in contested cases
• Outstanding tax demands are credit risk signals that lenders assess during GST-based underwriting

Conclusion

GST notices are the system’s feedback mechanism, flagging inconsistencies before they become entrenched compliance failures. For businesses that maintain accurate, reconciled records and file on time, responding to a scrutiny notice is typically a documentation exercise, not a financial crisis. For those with significant discrepancies or aggressive positions, notices are the starting point for a more serious proceeding.

The most cost-effective approach to GST notice management is prevention: monthly GSTR-2B reconciliation, consistent GSTR-1 and GSTR-3B alignment, and the discipline to reverse and pay when an error is discovered, before it becomes a notice. Running a full GST reconciliation to resolve the discrepancies cited in the notice — before filing your response — is the single most effective preparation step.
