Trunk Road Porur GST Audit Support for retail Businesses

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 (4) of Section 65 prescribes that the audit shall be completed within three months from the date of commencement of the audit. The proviso permits the Commissioner, where satisfied that the audit cannot be completed within three months for reasons to be recorded in writing, to extend the period by a further period not exceeding six months. The expression date of commencement is defined in the Explanation to mean the date on which the records and other documents called for by the tax authorities are made available by the registered person, or the actual institution of audit at the place of business, whichever is later.

Sub-section (5) of Section 35, as it stood prior to amendment by the Finance Act 2021, required every registered person whose turnover exceeded the prescribed threshold to get his accounts audited by a chartered accountant or a cost accountant and submit a copy of the audited annual accounts, the reconciliation statement and other documents in the prescribed form. The Finance Act 2021 omitted this sub-section with effect from 1 August 2021. It is to be noted that the GSTR-9C reconciliation statement is now a self-certified document under Rule 80.

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.

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.

Rule 56 stock records

Reconstruction of stock records during audit

Where stock records under Rule 56(2) are incomplete or absent — a common scenario in SME manufacturing and trading — reconstruction during the ADT-01 fifteen-day window is the standard response. The reconstruction sources include purchase invoices and GSTR-2A entries (for inward stock), GSTR-1 outward supplies (for sales), e-way bill data (for stock movements), bank statements (for cash purchases or sales not invoiced through GST channels), and stock-take working papers from the statutory audit under the Companies Act or Section 44AB income tax audit. Reconstruction must be contemporaneous with the original transaction dates; backdated reconstruction is treated as fabrication by the audit team. The Tapas Dutta v UoI line of authority on retrospective records is occasionally invoked, but registered persons should not rely on it as a safe harbour.

Stock-difference treatment under Section 35(6) and Section 17(5)(h)

Where audit identifies stock differences — physical stock at audit visit differing from book stock — two provisions operate. Section 35(6) deems the unaccounted goods to have been supplied and attracts tax under Sections 73 / 74. Section 17(5)(h) blocks ITC on goods lost, stolen, destroyed, written off, or disposed of by way of gift or free sample, requiring reversal of the ITC originally claimed. The audit team typically computes both legs — output tax on the deemed supply, and ITC reversal on the inward leg — leading to a double-impact. Voluntary disclosure of stock-differences with documented reasons (e.g. shrinkage, wastage, theft with FIR copy) limits the exposure; the audit team's discretion under Section 75 allows mitigation where reasons are substantiated.

Sectoral application of Rule 56(18) — jewellery, precious metals

Rule 56(18) applies to a narrow but high-revenue-risk band of trades — precious metals, precious stones, jewellery — where stock-record granularity is essential because of the high unit-value and pilferage-risk profile. The daily quantity-wise register must capture purity (in carats for gold), weight (in grams or pennyweights), make-charges component, hallmarking certificate references (BIS hallmark unique identification), and customer-wise sale-bill traces. Family-run jewellery businesses in particular often default to consolidated weekly or monthly stock summaries; this gap is the most common audit finding in jewellery-sector Section 65 audits in Tamil Nadu. Coordinated compliance with TCS under Section 206C(1F) at 1% on sales above ₹2 lakh adds an income-tax overlay to the stock-records architecture.

GSTR-9C self-certification interplay with audit

Self-certification regime from FY 2020-21

Notification 29/2021-CT and the Finance Act 2021 substitution of Section 35(5) shifted GSTR-9C from CA / CMA attested certification to self-certification by the registered person, effective from financial year 2020-21 onwards. The reconciliation statement now bears the signature of the registered person or the authorised signatory; the previous Part B CA-CMA certification has been dropped. The substantive contents of GSTR-9C — Part A (reconciliation between audited financial statements and GSTR-9, covering turnover Table 5, taxable value Table 7, tax payable Table 9, ITC Tables 12-14) and Part B (auditor certification, now omitted) — are otherwise broadly retained. The threshold for GSTR-9C continues to be aggregate turnover above ₹5 crore, per Notification 16/2022-CT.

GSTR-9C as audit working paper

From the Section 65 audit-team perspective, GSTR-9C is the primary working paper that drives initial audit-topic selection. Table 5 turnover reconciliation surfaces unbilled-revenue, advance-receipt and inter-State stock-transfer issues. Table 7 taxable-value reconciliation surfaces classification and exemption-claim issues. Table 9 tax-payable reconciliation triggers rate-of-tax interrogation. Tables 12 to 14 ITC reconciliation drive Section 16 eligibility and Rule 42 / 43 apportionment audits. The audit team treats unexplained variances in any of these tables as priority interrogation topics; the registered person's strongest defence is a contemporaneous explanatory note attached to GSTR-9C addressing each material variance. CBDT Circular 8/2021 (in the AIS context, on reconciliation principles) and CBIC Circular 124/43/2019-GST on GSTR-9C format offer guidance.

Self-certification risk and director / signatory liability

The shift to self-certification has not reduced substantive accuracy expectations — Section 47(2) penalty for late filing applies, Section 35(5) (as amended) read with Section 122 attracts penalty for incorrect particulars, and Section 137 imposes personal liability on directors, partners and managers for company offences subject to the proviso on diligence. The signatory's diligence in reviewing the underlying GSTR-9 and GSTR-9C contents is now a personal-liability risk, where previously the CA / CMA certifier's professional liability provided an intermediating layer. The OECD International VAT/GST Guidelines' principle of taxpayer self-assessment with audit verification is well-served by the self-certification design, but it shifts more responsibility onto the registered person's internal-control architecture.

Section 67 inspection and its relation to audit

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.

Section 67 framework and reason-to-believe trigger

Section 67 of the CGST Act empowers the proper officer not below the rank of Joint Commissioner, upon reasons to believe recorded in writing, to inspect any place of business of a taxable person or any other person engaged in the business of transporting goods or owner or operator of a warehouse or godown, and to search and seize goods, documents, books and things. The Section 67 power is enforcement-oriented, triggered by suspicion of tax evasion (suppression of supply, claim of ITC in excess of entitlement, contravention of Act or rules), and is distinct from the verification-oriented Section 65 audit. The audit-to-inspection escalation occurs where Section 65 audit finds material gravity that the proper officer reads as warranting enforcement action under Section 67.

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.
