Guindy Industrial Estate GST Audit Support — Chennai South

Sub-section (1) of Section 65 of the Central Goods and Services Tax Act empowers the Commissioner, or any officer authorised by him through a general or specific order, to undertake audit of any registered person for such period, frequency and manner as may be prescribed. Sub-section (2) provides that the audit may be conducted either at the place of business of the registered person or at the office of the proper officer. It is to be noted that this provision is the substantive source of departmental audit jurisdiction and is read with Rule 101 for procedural mechanics.

Sub-section (1) of Section 66 provides that if at any stage of scrutiny, inquiry, investigation or any other proceedings, the officer not below the rank of Assistant Commissioner, having regard to the nature and complexity of the case and the interest of revenue, is of the opinion that the value has not been correctly declared or the credit availed is not within the normal limits, he may, with prior approval of the Commissioner, direct the registered person to get the records including books of account examined and audited by a chartered accountant or a cost accountant nominated by the Commissioner.

Sub-rule (1) of Rule 101 provides that the period of audit shall be a financial year or part thereof or multiples thereof. Sub-rule (2) prescribes Form GST ADT-01 for the audit notice. Sub-rule (4) directs the proper officer, on conclusion of audit, to record the audit observations in his audit notes and to inform the registered person of the discrepancies, who may file his reply. Sub-rule (5) prescribes Form GST ADT-02 for communication of audit findings.

Sub-section (1) of Section 35 obliges every registered person to keep and maintain, at his principal place of business, a true and correct account of production or manufacture of goods, inward and outward supply of goods or services, stock of goods, input tax credit availed, output tax payable and paid, and such other particulars as may be prescribed. It is to be noted that the records framework under this section is the substratum on which any audit, scrutiny or adjudication proceeds.

Section 73 governs the determination of tax not paid, short paid, erroneously refunded, or input tax credit wrongly availed for reasons other than fraud, wilful misstatement or suppression of facts. Sub-section (1) requires the proper officer to issue a show-cause notice at least three months prior to the time-limit specified for issuance of order under sub-section (10). It is to be noted that post-audit adjudication frequently routes through Section 73 unless suppression is alleged.

Sub-section (3) of Section 65 provides that the registered person shall be informed by way of a notice not less than fifteen working days prior to the conduct of audit. The notice is issued in Form GST ADT-01 as prescribed under Rule 101(2). It is to be noted that the fifteen-working-day window is a substantive procedural safeguard; commencement of audit proceedings without compliance with this timeline is a jurisdictional infirmity that may be agitated under Article 226.

What is a GST audit and where does it sit in the compliance architecture

Self-certification under GSTR-9C and its audit interplay

Until Finance Act 2021 amendments, Section 35(5) had required certification of GSTR-9C by a Chartered Accountant or Cost Accountant for registered persons whose aggregate turnover exceeded the prescribed threshold. The Finance Act 2021 substituted Section 35(5) and amended Section 44, shifting GSTR-9C to a self-certified reconciliation statement filed by the registered person without third-party attestation, effective FY 2020-21 onwards (Notification 29/2021-CT). The reconciliation in GSTR-9C between audited financial statements and GSTR-9 annual return is now an internal-control disclosure; it does not substitute for departmental audit under Section 65. Audit teams treat GSTR-9C self-certified reconciliations as primary working papers — Table 5 (turnover reconciliation), Table 9 (tax payable reconciliation) and Table 12-14 (ITC reconciliation) become the starting points of Section 65 audit interrogation.

Comparative framework — VAT/CST audits versus GST audit

Pre-GST, the VAT regime in Tamil Nadu (Tamil Nadu VAT Act 2006) had an audit framework under Section 64 with mandatory CA audit certificates for dealers above prescribed turnover, and the Central Sales Tax framework had limited audit coverage focused on inter-State transactions. The GST framework consolidates and rationalises this — a single audit under Section 65 covers central, State and integrated tax dimensions; the cooperative-federal architecture under Article 246A and 279A means the audit can be conducted by either the central or State authority but not both (Section 6 cross-empowerment). The OECD International VAT/GST Guidelines emphasise audit-efficiency through risk-based selection and digital data analytics, both of which the Indian framework has incorporated through GSTN-driven analytics and the GSTR-9C self-certification feed.

Statutory framework under Chapter XIII of the CGST Act

The audit framework under the Central Goods and Services Tax Act 2017 is contained in Chapter XIII, comprising Sections 65, 66 and 71. Section 65 provides for departmental audit, Section 66 for special audit by a Chartered Accountant or Cost Accountant nominated by the Commissioner, and Section 71 for access to business premises by an authorised officer. The Empowered Committee 2009 First Discussion Paper had envisaged audit as the principal verification layer in a self-assessment regime, replacing the pre-GST pattern of routine assessment under the VAT/CST framework. The architecture is risk-based: not every registered person is audited; selection is driven by Section 65(2) read with internal CBIC risk-management directions which factor in turnover scale, sectoral risk profile, prior compliance history and reconciliation gaps surfaced in GSTR-9C self-certification. The audit-process closure under Section 65(7) feeds either into a no-objection certificate, a voluntary DRC-03 payment, or an SCN under Section 73 or Section 74 depending on whether tax has been short-paid, short-collected or wrongly availed as ITC.

Section 67 inspection and its relation to audit

Audit-to-inspection escalation patterns

In practice, Section 65 audit findings escalate to Section 67 inspection where the audit team identifies indicators of deliberate evasion — fake invoicing patterns, circular trading rings, ITC claimed against suppliers whose registrations are cancelled or who have nil GSTR-3B filings (Suncraft Energy and downstream judicial line), classification mis-applications that appear deliberate. The escalation is not automatic; the proper officer must form a fresh reason-to-believe under Section 67(1) and record reasons. The Pradeep Goyal (Supreme Court on DIN — Document Identification Number for tax notices) framework requires the inspection authorisation to bear a valid DIN, failing which the action is voidable. The GKN Driveshafts (India) v ITO principle on opportunity-of-being-heard before invasive action is occasionally invoked but its application in the Section 67 context is restricted.

Procedural safeguards under Section 67(2) to 67(10)

Section 67(2) requires that search and seizure shall be carried out in the manner prescribed under Rule 139; provisions of the Code of Criminal Procedure 1973 relating to search and seizure apply mutatis mutandis (Section 67(10)). Section 67(7) provides that goods so seized shall be returned within six months extendable by six months for sufficient reasons. Section 67(8) preserves the registered person's right to make copies of the seized documents. The procedural safeguards exist; the OECD Forum on Tax Administration recommends similar safeguards as part of the taxpayer-rights framework. In practice, the Bharti Airtel v UoI and Suncraft Energy v Asst Commissioner lines of authority have shaped the procedural-fairness review of Section 67 actions in writ jurisdiction before the Madras High Court and other High Courts.

Comparative framework — pre-GST excise / service tax and current GST

Pre-GST, the Central Excise Act Section 14 provided summons power, Section 18 search power, and Section 12F seizure power. Service tax under the Finance Act 1994 had similar provisions under Sections 82 (search) and 73 (recovery). The GST framework consolidates these into Section 67 with unified procedural architecture. The Empowered Committee 2009 First Discussion Paper had envisaged a single-window enforcement architecture replacing the fragmented pre-GST regime; Section 67 substantively delivers that design. Comparative OECD International VAT/GST Guidelines emphasise that enforcement powers should be calibrated to the gravity of the suspected evasion, and the Indian framework's reason-to-believe-plus-Joint-Commissioner-rank gating mechanism aligns with that principle.

Audit-to-DRC-01 escalation

Section 73 versus Section 74 framing post-audit

Where audit findings are not addressed through voluntary DRC-03 payment, the proper officer issues a Show Cause Notice — DRC-01 under Section 73(1) for cases not involving fraud, wilful misstatement or suppression, and under Section 74(1) for cases involving any of those elements. The framing choice has material consequences. Section 73 attracts penalty of 10% of tax or ₹10,000 whichever is higher (Section 73(9)), with no penalty if voluntary payment is made within thirty days of SCN under Section 73(8). Section 74 attracts penalty of 100% of tax (Section 74(9)), with reduced penalty of 25% if voluntary payment is made within thirty days of SCN under Section 74(8) and 50% within thirty days of order. The extended-period limitation of five years (versus three years under Section 73) is the other material difference.

Defending Section 74 fraud framing

Where the audit-team recommends Section 74 framing, the registered person's defence focuses on the four elements — fraud, wilful misstatement, suppression of facts, or contravention with intent to evade tax. The Supreme Court's pre-GST jurisprudence on similar language in Central Excise (Pushpam Pharmaceuticals v CCE) and Service Tax (CCE v Mehta and Co) emphasised that mere non-payment or non-disclosure does not amount to suppression with intent; positive indicators of intent are needed. Bona-fide classification errors, computational mistakes, and reasonable interpretation differences are not suppression. Where the SCN frames the case under Section 74, the response should systematically address each of the four elements and rely on the documentary trail showing bona-fide compliance attempts. Pradeep Goyal (DIN requirement) and Kranti Associates (reasoned order) provide procedural safeguards.

Limitation analysis post audit

Section 73(10) provides that the order under Section 73 shall be issued within three years from the due date for furnishing of annual return for the financial year to which the tax not paid or short paid or input tax credit wrongly availed relates; the SCN must be issued at least three months before that date (Section 73(2)). Section 74(10) provides corresponding five-year limitation. For FY 2017-18 GSTR-9 (annual return due 31 December 2018, extended dates apply), the Section 73 limitation expired in late 2021-22 (extended through various Notifications including 9/2023-CT to 31 December 2023 and further), and Section 74 limitation extends to mid-2024 onwards. Audit findings escalated beyond limitation are barred; the registered person should systematically test limitation as part of the SCN defence.

Common audit findings

Place-of-supply errors and IGST versus CGST/SGST

Place-of-supply errors are the fourth common finding — typically where the registered person charged CGST/SGST (intra-State) when the place of supply under Sections 10 to 13 IGST Act was inter-State (requiring IGST), or vice versa. Section 77 of the CGST Act provides a corrective mechanism — where tax was paid under one head but is actually payable under another, the wrongly-paid tax can be claimed as refund and the correctly-payable tax should be paid; the registered person is not penalised, only interest under Section 50 may apply. Audit teams sometimes overlook Section 77 and compute full short-payment additions; citing Section 77 with documented evidence of the corresponding refund-eligible head closes the issue at audit stage.

ITC mismatch between GSTR-2A / 2B and GSTR-3B

The single most common Section 65 audit finding is ITC mismatch — ITC claimed in GSTR-3B Table 4(A) exceeding ITC available in GSTR-2A or GSTR-2B for the corresponding tax period. The post-2019 regulatory tightening — Rule 36(4) initially capping un-uploaded ITC at 20%, then 10%, then 5% (Notification 75/2019-CT, 49/2019-CT, 94/2020-CT trajectory), then Section 16(2)(aa) mandating GSTR-2B as the eligibility baseline (Notification 39/2021-CT effective 1 January 2022) — has progressively tightened the mismatch tolerance to nil. Audit findings on FY 2020-21 onwards typically computes the mismatch quarter-wise; the registered person's defence rests on vendor-wise reconciliation, vendor follow-up correspondence, and the Suncraft Energy bona-fide-buyer principle where applicable.

Reverse-charge under Sections 9(3) and 9(4) — self-invoice gaps

The second-most-common audit finding is missed reverse-charge — supplies where the recipient is liable to pay tax under Section 9(3) (notified categories — GTA without forward-charge election, legal services, sponsorship, services by directors, etc.) or Section 9(4) (supplies from unregistered to registered persons in notified categories for real-estate developers under Notification 07/2019-CT(R) read with 03/2019-CT(R)). Section 31(3)(f) requires the recipient to issue a self-invoice; many registered persons miss this step. The audit-team computes the missed output liability under reverse-charge, the corresponding ITC eligibility (subject to time-limit under Section 16(4)), and the interest under Section 50. Voluntary disclosure via DRC-03 is the standard close-out.
