Statutory hooks that bite here — In Athipet Ambattur, Athipet Ambattur businesses in the auto components arm find that tier-2 component suppliers face GST classification disputes between HSN 8708 and 8483 and frequent ITC reversal notices; where SIDCO-CMDA developed engineering units operate on B2B procurement and capital-goods ITC accumulation cycles.
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.
View sourceSub-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.
View sourceSub-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.
View sourceSub-rule (1) of Rule 102 prescribes Form GST ADT-03 for the direction by the proper officer to the registered person to get his records audited by a chartered accountant or cost accountant nominated by the Commissioner under Section 66. Sub-rule (2) prescribes Form GST ADT-04 for communication of findings of the special audit to the registered person. It is to be noted that ADT-04 is the formal closure document of the special-audit track.
View sourceSub-section (6) of Section 65 requires the proper officer, on conclusion of audit, to inform the registered person within thirty days of the findings, the registered person's rights and obligations, and the reasons for such findings. The communication is issued in Form GST ADT-02. It is to be noted that the thirty-day window is mandatory and starts on the date of conclusion of audit, not the date of the audit report.
View sourceSub-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.

Section 65 departmental audit and Section 66 special audit representation for Athipet Ambattur businesses — ADT-01 notice handling, on-site audit support, ADT-02 reply drafting and DRC-03 closure under Rule 101 of the CGST Rules.
A dedicated GST audit consultant in Athipet Ambattur prepares Table 8 GSTR-9 reconciliation, Section 17(5) workings, RCM register reconstruction and litigation-grade documentary backup for the full 6-year Section 36 retention window.
On receipt of ADT-01, all 12 months of returns plus audited financials, ITC ledger and e-invoice IRN logs are compiled within the 15 working days notice window — and ADT-02 findings are replied with Section 16 case-law backing including Tvl. Diya Agencies.
For Athipet Ambattur businesses with aggregate turnover above ₹5 crore, GSTR-9C reconciliation between audited financials and GSTR-9 is self-certified and filed before 31st December along with full Table 8 ITC tie-up.
The audit unit is each GSTIN; assessment and book-keeping are GSTIN-specific even where the underlying PAN is common. The Tamil Nadu registration of a pan-India taxpayer is audited independently by the jurisdictional CGST or SGST authority covering that GSTIN.
ADT-02 is the audit-findings report under Rule 101(5) at the end of a Section 65 audit. DRC-01 is the show-cause notice issued under Section 73 or 74 read with Rule 142 to demand tax. ADT-02 findings, if disputed, mature into a DRC-01 SCN separately.
DRC-03 is the voluntary-payment intimation under Rule 142(2). It is used to discharge tax with interest before SCN to invoke Section 73(5) or 74(5) immunity, or to comply with ADT-02 findings. Closure follows through DRC-04 or DRC-05 as the case may be.
Section 73(5) permits payment of tax with interest before any show-cause notice is issued. Where so paid through DRC-03 referencing the audit ARN, no penalty is leviable and proceedings stand closed for that amount on issue of DRC-04 by the proper officer.
ADT-02 itself is a finding, not a demand. The demand crystallises only through a subsequent DRC-01 SCN and the consequential DRC-07 order. First appeal under Section 107 against that order lies within three months on a ten per cent pre-deposit of disputed tax.
Suncraft Energy Pvt Ltd v Assistant Commissioner of the Calcutta High Court holds that input tax credit available to a bona fide recipient cannot be defeated solely on supplier-side default in GSTR-1 filing or tax payment, where the recipient holds valid invoices and discharged consideration including tax.

Reading this guide locally — In Athipet Ambattur, in the industrial cluster within aie micro-market of Athipet Ambattur; Athipet Ambattur businesses in the heavy manufacturing arm find that GST inverted-duty refunds capital-goods ITC and Rule 42/43 apportionment dominate the compliance workload.
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.
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.
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 of the CGST Rules elaborates the records to be maintained under Section 35 — accounts of goods or services received and supplied, stock of goods (with opening balance, receipt, supply, goods lost stolen destroyed written off or disposed of by way of gift or free sample, balance), particulars of ITC availed, output tax payable and paid, names and complete addresses of suppliers and customers, complete addresses of premises where goods are stored including goods stored during transit, monthly production accounts (for manufacturers) showing quantitative details of raw materials and goods produced, and accounts of advances received and paid. Rule 57 provides for maintenance through electronic means with prescribed safeguards. Rule 58 covers transporter, owner and operator of warehouse records. The records-architecture is granular and audit teams systematically map registered-person records against the Rule 56 schema during Section 65 audits.
Failure to maintain accounts and records as prescribed under Section 35 read with Rule 56 attracts consequences under multiple provisions. Section 35(6) empowers the proper officer to determine the tax payable on the goods or services or both not accounted for as if such goods or services or both had been supplied by such person, and the provisions of Sections 73 or 74 shall apply for determination of such tax. Section 122 provides for penalty for various offences including failure to maintain records — up to ₹10,000 or the amount of tax evaded, whichever is higher. The audit team's working assumption in cases of inadequate records is that the burden shifts to the registered person to demonstrate the correctness of declared turnover and ITC; this evidentiary shift is the most material consequence in practice.
The GST retention framework operates alongside the Income Tax Act Section 44AA requirement to maintain books of account for specified professions and businesses (with retention under Rule 6F for six years), and the Companies Act 2013 Section 128 requirement for books of account preservation for at least eight years preceding the current year. The longest applicable horizon governs — for a company carrying on a taxable supply business, the effective records-retention period is the Companies Act eight-year horizon. The OECD International VAT/GST Guidelines recommend a minimum retention of five years tied to the audit-period limitation, which the Indian GST framework comfortably exceeds. Coordinated retention policies across GST, income tax and Companies Act dimensions are the typical compliance design at well-run enterprises.
Rule 56(2) of the CGST Rules requires every registered person, other than a person paying tax under Section 10 (composition), to maintain accounts of stock in respect of goods received and supplied — showing opening balance, receipt, supply, goods lost, stolen, destroyed, written off or disposed of by way of gift or free sample, and balance of stock including raw materials, finished goods, scrap and wastage. Rule 56(18) imposes a higher-granularity obligation on registered persons dealing in goods of the kinds notified — currently primarily precious metals, precious stones and jewellery — requiring daily quantity-wise and value-wise stock registers. The granularity differential between Rule 56(2) and Rule 56(18) reflects the sector-specific revenue-risk assessment that has been part of Indian indirect-tax administration since pre-GST excise.
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.
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.
For registered persons whose aggregate turnover is between ₹2 crore and ₹5 crore (where GSTR-9 is optional under Notification 47/2019-CT and similar; GSTR-9C threshold is above ₹5 crore), the strategic question is whether to file GSTR-9 and GSTR-9C voluntarily. Voluntary filing provides a contemporaneous reconciliation record that strengthens the audit-defence position; non-filing leaves the audit team to compute reconciliation themselves from primary records, often less favourably. The GST Council 47th Chandigarh and 53rd meetings have periodically rationalised these thresholds; the Empowered Committee 2009 First Discussion Paper had envisaged annual-return-as-integrating-layer architecture that the current threshold-based structure has partially diluted.
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.
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.

Section 74 of the CGST Act governs the determination of tax not paid, short paid, erroneously refunded or input tax credit wrongly availed by reason of fraud, wilful misstatement or suppression of facts to evade tax. The limitation extends to five years from the due date of the annual return. Penalty equal to the tax demanded is leviable.
Rule 101 of the CGST Rules prescribes the procedure for audit under Section 65. Sub-rule (1) provides that the audit period shall be a financial year or part thereof or multiples thereof. Sub-rule (2) prescribes Form ADT-01 for the audit notice. Sub-rule (4) deals with discrepancy notes and sub-rule (5) prescribes Form ADT-02 for communication of findings.
Rule 102 of the CGST Rules prescribes the procedure for special audit under Section 66. Sub-rule (1) prescribes Form ADT-03 for the direction to the registered person, and sub-rule (2) prescribes Form ADT-04 for communication of the findings of the special audit to the registered person.
Place of audit is governed by sub-section (2) of Section 65 which permits the audit to be conducted either at the place of business of the registered person or at the office of the proper officer. The choice rests with the department; the registered person does not have a unilateral right to require off-site audit.
Date of commencement of audit is defined in the Explanation to sub-section (4) of Section 65. It is 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. The ninety-day completion clock runs from this date.
Conclusion of audit is the point at which the field-verification and records-examination work under Section 65 is finished. The thirty-day clock for issuance of ADT-02 under sub-section (6) of Section 65 starts running from conclusion. Conclusion is distinct from the date of communication of findings.
Period of audit under sub-rule (1) of Rule 101 shall be a financial year or part thereof or multiples thereof. A multi-year audit is permissible where the audit notice in ADT-01 specifies the periods covered. The earliest period audited typically corresponds to records retention horizon under Section 36.
Audit notes are the contemporaneous record maintained by the proper officer during the conduct of audit under Rule 101. Discrepancies recorded in the audit notes are communicated to the registered person under sub-rule (4) of Rule 101 with an opportunity to reply before the findings are crystallised in ADT-02.
Discrepancy memo is the informal communication, contemplated under sub-rule (4) of Rule 101, by which the proper officer informs the registered person of observations recorded during audit. The registered person files a written reply with supporting reconciliations before ADT-02 is issued.
Books of account refer to the records required to be maintained under sub-section (1) of Section 35 of the CGST Act — accounts of production or manufacture, inward and outward supply, stock, ITC availed, output tax payable and paid. Maintenance at the principal place of business is the default; additional places require records of the additional location.
Records retention under Section 36 is the obligation to preserve books of account and other records until the expiry of seventy-two months from the due date of furnishing the annual return for the financial year. Where appeal or revision is pending, retention extends until one year after final disposal of the proceeding.
Self-certification under Rule 80(3) is the framework that, with effect from 1 August 2021, replaced mandatory audit by a chartered accountant or cost accountant for GSTR-9C. The registered person self-certifies the reconciliation statement; the substantive content of GSTR-9C continues to be governed by the form.

“Received an ADT-01 audit notice for FY 2020-21 and FY 2021-22. FilingPro compiled all 24 months of returns, reconciled GSTR-1 vs GSTR-3B vs books and prepared Table 8 GSTR-9 working before the audit team arrived. ADT-02 had only minor findings — closed via DRC-03 with no demand notice.”
“Our ITC of ₹38 lakh was being questioned because some suppliers had not filed GSTR-1. FilingPro defended the credit citing Tvl. Diya Agencies and demonstrated Section 16 compliance with payment evidence. Audit team accepted the position — full ITC retained.”
“Section 66 special audit was ordered for our trading business. FilingPro coordinated with the Commissioner-nominated CA, gave full record access, prepared Section 17(5) workings and RCM register. Final report had no adverse findings on valuation or ITC.”
“GSTR-9C self-certification for our ₹12 crore turnover business was handled by FilingPro for FY 2022-23 and FY 2023-24. Reconciliation between audited financials and GSTR-9 was tight — no Table 8 difference, no HSN summary gap. Filed before 31 December both years.”
