A GST show cause notice under Section 73 or Section 74 of the CGST Act, 2017 is not self-executing. Before any demand order stands, the SCN must survive 15 tested legal challenges — procedural defects, limitation bars, substantive merit failures, and natural justice violations — each of which has produced successful High Court writs quashing demand orders. This is your triage checklist.
The §73 vs §74 threshold: the question you must answer first
Before reviewing any specific ground, establish which provision was invoked. Section 73 covers tax shortfalls arising without fraud or wilful misstatement — penalty is capped at 10% of tax (minimum ₹10,000), limitation is 3 years from the due date of the annual return. Section 74 applies only where the officer can establish fraud, wilful misstatement, or suppression of facts with intent to evade tax — penalty is 100% of tax, limitation is 5 years.
Getting this wrong is the most consequential error in a GST demand proceeding. On a ₹50 lakh demand, the penalty difference between §73 and §74 is ₹45 lakh. Every other ground builds from this threshold question.
Procedural and limitation grounds (Grounds 1–6)
Ground 1 — Wrong provision invoked: §74 used when §73 applies
Section 74 can only be invoked where the officer establishes — not merely alleges — fraud or suppression with intent to evade. A reconciliation mismatch between GSTR-2B and GSTR-3B, a classification error made in good faith, or a transitional ITC dispute falls within §73 territory. High Courts across Punjab and Haryana, Delhi, and Gujarat have quashed §74 SCNs based solely on ITC mismatches, holding that intent to evade cannot be inferred from a number gap alone. CBIC Circular 171/03/2022-GST (CIR_171_2022) itself limits §74 to cases where fraudulent intent is specifically established.
Ground 2 — SCN is time-barred: issued beyond the 3-year or 5-year limitation
Under Section 73(10) CGST Act, the §73 SCN must be issued within 3 years from the due date of the annual return (GSTR-9) for the relevant financial year. Section 74(10) gives 5 years. The limitation period runs from the notified due date of GSTR-9 — which was extended multiple times post-GST launch. COVID-period extensions under CGST Notifications 35/2020 and 55/2020 added approximately 5 months for FY 2017–18 and 2018–19 demands. The Delhi HC and Gujarat HC have quashed demand orders on limitation grounds, holding this is a jurisdictional ceiling — no equitable extension applies.
Ground 3 — DRC-01A omitted: mandatory pre-notice consultation step skipped
Rule 142(1A) of the Central Goods and Services Tax Rules, 2017 requires the proper officer to communicate the ascertained tax, interest, and penalty via Form DRC-01A before issuing any SCN under §73(1) or §74(1). The word "shall" makes this mandatory, not directory. The Allahabad HC in M/s Garg Enterprises v. State of UP and several Delhi HC decisions have held that omitting DRC-01A vitiates the subsequent SCN, as it denies the taxpayer the statutory right to settle before formal proceedings begin.
Ground 4 — SCN signed by officer below prescribed rank
Section 2(91) CGST Act defines "proper officer" as the jurisdictionally-assigned officer. CBIC Notification 2/2017-Central Tax (27 June 2017) prescribes monetary thresholds for officer rank: Deputy/Assistant Commissioners handle demands up to ₹5 crore; Joint Commissioners handle demands above ₹5 crore; Commissioners handle demands above ₹50 crore. An SCN issued by a Superintendent or Inspector for a demand that exceeds the Superintendent's monetary jurisdiction is void for want of authority. Delhi HC has applied the Anisminic principle — an ultra vires act by a functionally incompetent officer is a nullity.
Ground 5 — SCN lacks specificity: vague allegations fail minimum content requirements
An SCN must inform the taxpayer, with reasonable particularity, of: the specific transactions in dispute, the supplier GSTINs and invoice numbers, the exact ITC amounts challenged, the tax period, and the statutory basis. An SCN that merely states "you have wrongly availed ITC" without specifying which invoices does not constitute a valid notice. The Allahabad HC quashed such a notice in Daulat Ram Ratan Kumar v. State of UP; Delhi HC in Bharat Forge Ltd v. Union of India (2019) held that absence of specific entry-level details renders the SCN fundamentally deficient.
Ground 6 — Personal hearing under §75(4) not given before adverse order
Section 75(4) CGST Act creates a mandatory obligation: "An opportunity of hearing shall be granted where... any adverse decision is contemplated against such person." This is automatic — not contingent on whether the taxpayer requested a hearing. In Bharti Airtel Ltd v. Union of India (Delhi HC, W.P.(C) 5765/2019), the court held that §75(4) is a mandatory precondition and any order passed without a personal hearing must be set aside. Bombay HC in Shree Naman Developers (2022) confirmed that a detailed written reply does not substitute for the personal hearing right.
Substantive and merit grounds (Grounds 7–13)
Ground 7 — §74 invoked without establishing fraud: ITC mismatch is not fraud per se
Section 74(1) CGST Act uses the phrase "by reason of fraud or any wilful misstatement or suppression of facts to evade tax" — the officer must identify specific conduct demonstrating intent to evade, not merely a tax gap. Gujarat HC quashed a §74 SCN in Aggrawal Timber v. State of Gujarat where the only basis for "suppression" was a GSTR-2A/3B mismatch. The Delhi HC and Bombay HC have consistently held that suppression requires deliberate withholding with intent to evade — a standard borrowed from the Supreme Court's pre-GST ruling in Union of India v. Dharmendra Textile Processors (2008) 13 SCC 369.
Ground 8 — ITC mismatch due to supplier non-filing: recipient cannot be penalised for supplier's default
Where ITC was availed on a facially valid invoice, goods were actually received, and payment was made through banking channels — the subsequent failure of the supplier to upload the invoice on GSTR-1 does not make the recipient's availment fraudulent. The Allahabad HC and multiple Delhi HC orders have held that §74 cannot be invoked against an innocent recipient for the supplier's non-compliance. The demand for ITC reversal may be framed as §73 at most; Section 16(2)(aa) and Rule 37A govern the reversal mechanism, but fraud cannot be attributed to the recipient.
Ground 9 — Wrong tax period: demand attributed to a different financial year than the supply
Sections 73 and 74 tie the demand to a specific financial year and return period. A demand attributing a supply to a tax period unsupported by the invoice date, supply date, or point-of-taxation under §§12–13 CGST Act is a jurisdictional defect. Gujarat HC in Aggrawal Timber v. State of Gujarat (2023) quashed a demand partly on this ground; Delhi HC has consistently held that the officer must match each disputed entry to the return period in which it should have been reported.
Ground 10 — Classification dispute: taxpayer had a reasonable basis for the HSN/SAC applied
Classification disputes — where the officer applies a different GST rate schedule entry than the taxpayer — are §73 territory where the taxpayer's position is reasonably tenable. The Supreme Court's doctrine of strict construction of charging provisions (from Commissioner v. Fiat India and STO v. Binani Cement) requires ambiguities in the rate schedule to be resolved in favour of the taxpayer. Where the taxpayer holds an Advance Ruling under §97–100 CGST Act, or where a CBIC circular or FAQ acknowledges the industry practice, §74 cannot be invoked.
Ground 11 — Demand already paid via DRC-03 before the SCN was issued
Section 73(5) CGST Act provides: "Where the person chargeable with tax makes payment... before issuance of notice under sub-section (1), no notice shall be issued." Rule 142(2) requires the officer to issue a Form DRC-04 acknowledgement and close the matter. Delhi HC quashed a §73 SCN in Vaibhav Enterprises v. Union of India (2023) where the taxpayer had filed DRC-03 covering the identical demand before the SCN date. The "no notice shall be issued" language is mandatory — the officer has no jurisdiction to issue the SCN post-payment.
Ground 12 — Principal-agent confusion: SCN demands GST from agent on principal's turnover
Where the taxpayer acts as a commission agent or consignment agent and the supply is the principal's supply being facilitated through the agent — not the agent's own supply — GST on the principal's turnover is not payable by the agent. Schedule I, para 3 CGST Act deems a supply only where the agent holds goods on behalf of the principal in the agent's own name. Bombay HC in Filco Trade Centre Pvt Ltd v. Union of India (2022) addressed this mischaracterisation for del credere agents. An SCN that attributes the principal's turnover to the agent fails at the foundational "who is the taxable person" level.
Ground 13 — §17(5) blocked-credit demand based on wrong categorisation
Section 17(5) blocks ITC in specified categories, but each category carries statutory exceptions. Common officer errors: treating all motor vehicles as blocked (goods transport vehicles are excepted); applying the works contract block to services for plant and machinery (CBIC Circular 219/13/2024-GST expressly clarified that OFC ducts and manholes qualify as plant and machinery); and applying the food/beverages block to a business whose own trade is catering. If an exception applies to the taxpayer's specific supply, the §17(5) block is inapplicable and the demand fails on the merits.

Natural justice grounds (Grounds 14–15)
Ground 14 — Adjudication order passed without considering the reply: non-speaking order
Section 75(6) CGST Act requires the proper officer to "set out the relevant facts and the basis of his decision" in the order. Where the taxpayer filed a detailed reply raising statutory arguments, documentary evidence, and case law — and the order either ignores the reply entirely or dismisses it with a single line — the order is a non-speaking order in violation of §75(6) and constitutional natural justice requirements. The Supreme Court in Kranti Associates Pvt Ltd v. Masood Ahmed Khan (2010) 9 SCC 496 affirmed this obligation. Madras HC in M/s D.Y. Beathel Enterprises v. State Tax Officer (2021) set aside a demand order passed 3 days after a detailed reply as factually impossible — indicating the reply was not considered.
Ground 15 — Order passed after the §73(10)/§74(10) limitation period expires
Even a timely SCN can produce an invalid order if the adjudication order itself is passed after the 3-year (§73) or 5-year (§74) outer deadline. The limitation period applies to the adjudication order, not only to the SCN. Delhi HC in M/s Pashupati Nath Rollers Pvt Ltd v. Principal Commissioner CGST held that §73(10) is a jurisdictional ceiling on the power to adjudicate. An order passed after the deadline — without a court-granted stay that excluded intervening time — is void and can be challenged directly in a writ petition under Article 226 of the Constitution without exhausting the §107 appellate remedy.
FAQ
Q1: What makes a §74 SCN legally vulnerable on the fraud threshold?
Section 74(1) CGST Act requires the officer to establish that the tax shortfall arose "by reason of fraud or any wilful misstatement or suppression of facts to evade tax." Courts have held this requires identifying specific conduct showing deliberate intent — not merely a number gap between GSTR-2B credits and GSTR-3B claims. An SCN that uses formulaic language ("with intent to evade tax") without specifying the exact transactions and conduct alleged fails this threshold and must be treated as a §73 notice — reducing maximum penalty from 100% to 10% of the demand.
Q2: Can you challenge a GST SCN before the adjudication order is passed, or must you wait for the order?
For pure procedural defects — limitation bar (Ground 2), DRC-01A omission (Ground 3), officer rank (Ground 4), and wrong-provision invocation (Ground 1) — courts have accepted writ petitions even at the SCN stage, before adjudication. The rationale: where the SCN itself is jurisdictionally void, compelling the taxpayer to participate in adjudication would be an imposition. For substantive merit challenges (Grounds 7–13), courts typically require the taxpayer to participate in adjudication first and then appeal under §107 CGST Act before invoking writ jurisdiction.
Q3: What happens if the personal hearing under §75(4) is denied?
An order passed without a §75(4) personal hearing is void, not merely voidable. The Delhi HC in Bharti Airtel Ltd v. Union of India (W.P.(C) 5765/2019) held that §75(4) is a mandatory precondition and the order must be set aside. The remedy is a writ petition under Article 226 of the Constitution to quash the demand order and remit the matter to the officer for fresh adjudication after affording a hearing. Importantly, the §107 appeal does not cure the §75(4) defect — if the hearing was not given at the adjudication stage, the appellate authority cannot retroactively validate the original order.
Q4: What is the limitation period for issuing a GST show cause notice, and how do you calculate it?
Under Section 73(10) CGST Act, the SCN must be issued within 3 years from the due date for filing the annual return (GSTR-9) for the financial year to which the demand relates. Under §74(10), the period is 5 years. For FY 2017–18, GSTR-9 due date was extended multiple times — the final extended date was 7 February 2020 for most taxpayers, giving a §73 outer date of approximately 7 February 2023. CGST Notification 35/2020 extended limitation for demands relating to FY 2017–18 and 2018–19. Verify the specific notified due date via the CBIC notification series before calculating.
Q5: If DRC-01A was not issued before the SCN, what is the remedy?
The omission of DRC-01A before a §73(1) or §74(1) SCN is a procedural defect under Rule 142(1A) CGST Rules. The remedy is to raise this as a ground in the reply to the SCN, requesting the officer to withdraw the SCN and restart from the DRC-01A stage. If the SCN proceeds to an adverse order despite the objection, the DRC-01A omission is a ground for a writ petition under Article 226 to quash the SCN and order. Allahabad HC in M/s Garg Enterprises v. State of UP and Delhi HC decisions have ordered proceedings to recommence from the DRC-01A stage in such cases.
Q6: Does paying tax under §73(5)/§74(5) before the SCN amount to admitting the demand?
No, if done correctly. Voluntary payment via Form DRC-03 under §73(5) or §74(5) triggers the penalty reduction benefit (nil penalty before SCN; 25% reduced penalty if paid before adjudication order under §73(8)/§74(8)). The payment should be accompanied by a covering letter expressly stating "payment made without prejudice to the taxpayer's right to dispute the characterisation of this demand as arising under §74 / to dispute the demand quantum / to dispute liability." Courts have accepted "without prejudice" DRC-03 filings as not constituting an admission of the fraud allegation or the quantum of the demand.
