Quick Answer

Can findings of a special audit be challenged in Ambattur Estate, Chennai?

Yes. Section 66(6) requires the registered person to be given an opportunity of being heard on any material gathered in the special audit which is proposed to be used in any proceeding. After the report, if the proper officer initiates a Section 73 or 74 demand based on the findings, the registered person can contest the demand through the regular SCN-reply-adjudication-appeal route.

People Also Ask — GST Audit Support in Ambattur Estate
What is the difference between Section 65 and Section 66 GST audit?
Section 65 is a departmental audit conducted by the Commissioner or an authorised officer at the place of business, with ADT-01 notice 15 working days in advance and 3-month completion (extendable to 6 months). Section 66 is a special audit ordered by an Assistant Commissioner (with Commissioner's approval) and conducted by an external Chartered Accountant or Cost Accountant nominated by the Commissioner, with 90-day report timeline (extendable by 90 days). Section 66 audit cost is borne by the Commissioner under Section 66(5).
How long must GST records be kept for audit?
Section 36 of the CGST Act read with Rule 56 requires retention for 6 years from the due date of the annual return for the relevant financial year. Where the registered person is party to any appeal, revision or proceeding, retention extends to one year after final disposal or 6 years — whichever is later. Cancellation of registration does not extinguish this obligation.
What happens if I do not respond to ADT-01 audit notice?
Non-response leads to ex-parte audit on the basis of available returns and information. Findings communicated via ADT-02 will be unfavourable since the taxpayer's books and reconciliations are absent. The proper officer can then issue DRC-01 under Section 73 or 74 followed by adjudication order under Section 73(9) or 74(9) creating tax demand with interest and penalty.
Can I voluntarily pay tax based on audit findings?
Yes. Where ADT-02 findings are accepted, the short-paid tax along with interest under Section 50 (and applicable penalty) can be voluntarily paid through Form DRC-03 on the GST portal. The proper officer then issues ADT-04 closure order. Voluntary payment under DRC-03 also helps avoid the DRC-01 SCN route under Section 73 or 74.
Is GSTR-9C audit by a CA still mandatory?
No. From FY 2020-21 onwards (Finance Act 2021 amendments) GSTR-9C is self-certified by the registered person, not certified by an external CA. The reconciliation between audited financials and GSTR-9 is prepared and filed by the taxpayer alongside GSTR-9 by 31st December, where aggregate turnover exceeds ₹5 crore in the financial year.
Can the same period be audited twice under GST?
Generally no. Once Section 65 audit is completed and ADT-04 closure order is issued, the same period cannot be re-audited under Section 65. Section 66 special audit is a separate power and may be ordered if the Assistant Commissioner forms an opinion on incorrect valuation or excess credit. Re-opening a closed audit requires fresh material and is exceptional.
What happens if records are not produced during ADT-01 audit?

Non-production attracts best-judgement reconstruction by the proper officer, Section 125 general penalty up to twenty-five thousand rupees, and adverse inference under the Indian Evidence Act principles. Section 70 summons may also be issued requiring personal attendance with records.

Can a writ petition be filed against an ADT-01 notice itself?

An Article 226 writ before the Madras High Court is maintainable against an ADT-01 notice where the notice lacks jurisdictional foundation, overlaps with an earlier audit on the same period without fresh material, or violates the speaking-order discipline recognised in Kranti Associates and GKN Driveshafts.

How does an ADT-02 finding mature into a tax demand?

ADT-02 records the audit conclusions. If the taxpayer does not voluntarily discharge through Form DRC-03, demand is crystallised by way of a show-cause notice in Form DRC-01 invoking Section 73 or 74 as the case may be, and eventually a DRC-07 adjudication order.

Are Tamil Nadu CGST and SGST audits coordinated?

Yes. The CBIC Single Interface for Facilitation by Tax Authorities framework coordinates Central and State audits to avoid duplication on the same GSTIN-period. The audit by one authority generally bars audit by the other for the same period absent fresh material.

Is professional representation permitted during a GST audit?

Yes. Section 116 permits an authorised representative including a Chartered Accountant, Cost Accountant or advocate to represent the registered person. Representation is widely used in {{area_name}} for ADT-01 audits and Section 66 special-audit coordination to ensure procedural rigour.

What is the difference between Section 65 audit and Section 66 special audit?

Section 65 is a departmental audit conducted by the proper officer at the registered person's place. Section 66 is a special audit ordered by an Assistant Commissioner directing a Commissioner-nominated Chartered Accountant or Cost Accountant to conduct the examination on specified grounds.

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

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.

Audit versus assessment versus inspection

Audit under Section 65 or 66 is conceptually distinct from assessment under Sections 61 (scrutiny of returns) and 62 (best-judgement assessment of non-filers) and from inspection / search / seizure under Section 67. Scrutiny under Section 61 is a desk-review of returns by the proper officer who issues ASMT-10 on discrepancies; the registered person responds in ASMT-11; closure or escalation follows. Audit is broader — Section 65(5) permits examination of the books, returns, statements, declarations and other documents to verify correctness of turnover declared, taxes paid, refund claimed and ITC availed, plus assessment of compliance with the Act. Inspection under Section 67 is targeted enforcement upon reason-to-believe of tax evasion and is invasive — premises access, seizure of records and goods. The OECD Forum on Tax Administration's compliance-pyramid model recommends graduated escalation from desk review to field audit to inspection, and the Indian framework broadly mirrors that design.

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.

Section 65 departmental audit framework

Powers of the audit team under Section 65(5) and Section 65(6)

Section 65(5) empowers the audit team to verify the documents, ascertain the correctness of turnover declared, exemptions and deductions claimed, rate of tax applied, ITC availed and utilised, refund claimed, and other relevant compliance matters. The team can examine any of these dimensions and require any explanation. Section 65(6) imposes a corresponding obligation on the registered person to afford the necessary facility to verify the books of account, statements and other documents called for, and to furnish information and render assistance for the timely completion of the audit. Reasonable cooperation is the registered person's first-line defence — obstruction or non-cooperation can trigger Section 71 access provisions and escalate the matter into Section 67 inspection territory.

Initiation under Section 65(1) and ADT-01 intimation

Section 65(1) of the CGST Act empowers the Commissioner, or any officer authorised by general or specific order, to undertake audit of any registered person for such period, at such frequency and in such manner as may be prescribed. Rule 101(2) of the CGST Rules read with Section 65(3) requires that the registered person be given not less than fifteen working days prior notice of audit through Form GST ADT-01. The ADT-01 intimation specifies the period proposed to be audited (typically one financial year, occasionally a longer span) and the documents to be made available — books of account, invoices, declarations, returns, GSTR-9C reconciliation statement, internal-audit reports if any. The fifteen-day window is the registered person's opportunity to gather records and seek extension on documented grounds; Rule 101(3) implicitly contemplates such extensions where genuinely warranted.

Audit period and frequency under Section 65(2)

Section 65(2) provides that the audit shall be conducted at the place of business of the registered person or in the office of the proper officer. The period covered is generally one financial year; multi-year audits are permissible where risk parameters warrant. Rule 101(1) limits the audit to a financial year unless the Commissioner specifically directs otherwise. The frequency of audit selection is risk-driven — the CBIC's Audit Manual (2019, periodically updated) directs Commissionerates to combine GSTN risk-engine outputs with sectoral profiles and prior-audit findings. Persons whose aggregate turnover crosses prescribed risk thresholds, or who have triggered specific red flags (large refund claims, sharp ITC growth versus output growth, GSTR-2A versus GSTR-3B mismatches), are prioritised. The GST Council 47th Chandigarh meeting (June 2022) had recommended a more nuanced risk-based selection to reduce small-taxpayer compliance burden.

Section 66 special audit by CA / CMA

Independence of Section 66 from prior audits or returns acceptance

Section 66(6) is a critical safeguard from the revenue's perspective — it provides that nothing in Section 66 shall be construed to debar the registered person from filing returns or paying tax, or to debar the proper officer from taking any action against the registered person under any other provision. The provision is non-derogating; a Section 66 special audit can be invoked even after a Section 65 departmental audit has been completed, where the proper officer forms a fresh opinion on value or credit complexity. Comparative jurisprudence in pre-GST excise (similar provision in Section 14A of the Central Excise Act before its omission) and service tax (Section 72A of the Finance Act 1994) had similar non-derogation features. The registered person's defence at the Section 66 stage rests primarily on the Section 75 opportunity-of-being-heard and the nature-of-complexity threshold.

Comparative framework — special audit in income tax and GST

The income-tax framework has a parallel under Section 142(2A) of the Income Tax Act 1961 — special audit can be directed where the Assessing Officer, having regard to the nature and complexity of the accounts, the volume of accounts, doubts about the correctness of the accounts, multiplicity of transactions in the accounts or specialised nature of business activity, is of the opinion that it is necessary in the interests of revenue. Pre-GST excise had Section 14A; service tax had Section 72A. The architectural unity across these provisions is that special audit is a complexity-triggered intervention requiring a substantive opinion plus a procedural safeguard. The OECD Forum on Tax Administration documents a similar 'specialist audit' tier in several mature tax jurisdictions, reserved for complex high-revenue cases.

Trigger conditions under Section 66(1)

Section 66(1) of the CGST Act provides that if at any stage of scrutiny, inquiry, investigation or any other proceedings, any 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 the prior approval of the Commissioner, direct such registered person by communication in writing to get his records including books of account examined and audited by a Chartered Accountant or a Cost Accountant as may be nominated by the Commissioner. The trigger requires both a substantive opinion (value mis-declaration or abnormal credit) and a procedural pre-condition (Commissioner's prior approval); the registered person can challenge either limb in a Section 75 representation.

ADT-01 intimation

Responding to ADT-01 — documentation readiness

Upon receipt of ADT-01, the registered person's first task is to map the document-schedule against actual maintained records and identify any gaps. Where records are incomplete (typically Rule 56 stock registers, Rule 89 refund working papers, or reverse-charge self-invoices under Section 31(3)(f)), the fifteen-day window is the opportunity for reconstruction. The Goetze (India) v CIT (2006) Supreme Court principle on the inability to make fresh claims outside the return framework (decided in the income-tax context) is sometimes invoked at the audit stage to deny ITC claims not appearing in original returns; the counter-position rests on Section 16(4) timeline arguments and the principle that audit is a verification not a re-assessment. Document submission within the fifteen-day window aligns the formal commencement of audit under Section 65(4) Explanation and tightens the three-month closure clock.

Seeking extension of the audit-commencement date

Where genuine grounds exist — pending statutory audit of financial statements, key personnel unavailability, or recent migration of accounting systems — the registered person can seek extension of the audit commencement date by written representation. The audit team has administrative discretion under Rule 101 to grant reasonable extensions, generally up to thirty additional days; longer extensions require Commissioner-level approval. The extension must be sought before the proposed commencement date and supported by documentary evidence (statutory auditor engagement letter, employee leave records, ERP migration plans). The OECD Forum on Tax Administration best-practice benchmarks recognise such extensions as a taxpayer-rights safeguard, balanced against the audit-closure timeline.

Risk-engine selection and audit-pool composition

ADT-01 intimations are not randomly issued; selection is driven by the GSTN risk engine combined with CBIC Audit Manual sectoral profiles. The risk engine factors include sharp variances between GSTR-1 and GSTR-3B, between GSTR-2A and GSTR-3B Table 4(A), between GSTR-9 and audited financial statements (via GSTR-9C), unusually high refund claims, sector-specific red flags (e.g. inverted-duty sectors, real-estate developers under Notification 03/2019-CT(R)), and prior-audit findings. The risk-based architecture aligns with the GST Council 47th and 53rd meeting recommendations on focusing enforcement on high-risk taxpayer cohorts while reducing nuisance audits of compliant small taxpayers. Knowing one's risk-profile drivers helps the registered person anticipate audit topics and prepare working papers accordingly.

What Ambattur Estate clients usually ask next: For Ambattur Estate engagements specifically — supporting the engineering and operator workforce that lives in the surrounding residential belts; where SIDCO-CMDA developed engineering units operate on B2B procurement and capital-goods ITC accumulation cycles; for Ambattur Estate units balancing production cycles with monthly GST and quarterly TDS compliance.

Glossary

Plain-English glossary for this service

Terms you will hear in this area — Across Ambattur Estate, where tier-2 and tier-3 component suppliers serve OEMs under DGS&D-style rate contracts with monthly GSTR-1 invoice volumes.

GSTR-9

GSTR-9 is the consolidated annual return prescribed under Section 44 read with Rule 80(1). It captures outward and inward supplies, ITC availed and reversed, taxes paid and demands or refunds for the financial year. GSTR-9 is the primary statutory return on which audit observations are anchored.

GSTR-9C

GSTR-9C is the self-certified reconciliation statement prescribed under Rule 80(3) reconciling the value of supplies declared in the annual return with the audited annual financial statement. It also reconciles tax paid and input tax credit. The threshold for applicability is aggregate turnover exceeding five crore rupees during the financial year.

Table 8 reconciliation

Table 8 of GSTR-9 captures the reconciliation between ITC available as per GSTR-2A or 2B and ITC availed in GSTR-3B. The difference under Table 8D is a frequent audit observation track. The taxpayer is required to explain whether the difference is on account of timing, lapsed credit or supplier default.

Records availability for 6 years

Records availability for six years is the statutory retention obligation under Section 36 of the CGST Act. Every registered person required to maintain books of account under Section 35(1) must retain them until the expiry of seventy-two months from the due date of furnishing the annual return for the relevant year. Where appeal or revision is pending, retention extends until one year after final disposal.

Reconciliation gap on Table 8

Reconciliation gap on Table 8 is a frequent finding in GST audit. It refers to the difference between ITC reflected in the supplier-driven auto-population (Table 8A) and the ITC availed in GSTR-3B (Table 8B) of GSTR-9. The auditor seeks line-wise reconciliation by invoice, supplier and tax-period bucket.

Adverse audit finding

Adverse audit finding is an observation recorded by the proper officer in the audit notes under sub-rule (4) of Rule 101 or in the communication under ADT-02 that points to short payment of tax, erroneous refund, or wrongly availed input tax credit. It is the precursor to action under Section 73 or Section 74.

Section 65

Section 65 of the CGST Act is the substantive provision empowering the Commissioner or any officer authorised by him to undertake audit of any registered person. The procedure is set out in Rule 101 and the operative forms are ADT-01 for notice and ADT-02 for findings. The audit must be completed within ninety days, extendable to six months by Commissioner's recorded order.

Section 66

Section 66 of the CGST Act is the special audit provision. The officer not below the rank of Assistant Commissioner, with prior approval of the Commissioner, may direct the registered person to get his records audited by a chartered accountant or cost accountant nominated by the Commissioner. The procedure is set out in Rule 102.

Section 35

Section 35 of the CGST Act is the records-maintenance provision. Sub-section (1) requires every registered person to keep and maintain books of account and records at the principal place of business. Sub-section (5), now omitted with effect from 1 August 2021, earlier required mandatory audit by a chartered accountant for turnover above the prescribed threshold.

Section 36

Section 36 of the CGST Act is the records-retention provision. Every registered person required to maintain accounts under Section 35(1) must retain them until the expiry of seventy-two months from the due date of furnishing the annual return for the financial year pertaining to the records. Pending appeal or revision extends the retention period.

Section 67

Section 67 of the CGST Act is the inspection, search and seizure provision. The proper officer not below the rank of Joint Commissioner, where he has reasons to believe that tax has been suppressed or credit has been wrongly availed with intent to evade tax, may authorise inspection of places of business. Section 67 is a distinct enforcement track and is not the same as the audit jurisdiction under Section 65.

Section 73

Section 73 of the CGST Act 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. Order under sub-section (10) may be passed within three years from the due date of annual return; SCN at least three months prior.

By Industry

Industry-specific patterns in Ambattur Estate

How the local trade mix shapes this — Across Ambattur Estate, where SIDCO-CMDA developed engineering units operate on B2B procurement and capital-goods ITC accumulation cycles. Practitioners note that the business activity radiating outward from Ambattur Industrial Estate and nearby commercial pockets.

Auto Components
Common issue: Tier-2 auto-component suppliers to OEMs face Section 65 audit queries on job-work reconciliation under Section 143 read with Rule 45 ITC-04 disclosure. Goods sent for job-work beyond the one-year (inputs) and three-year (capital goods) windows are deemed supplied; many auto-component units lose track of the ITC-04 quarterly cycle and face deemed-supply additions.
How we handle it: Reconstruct ITC-04 records quarter-wise from delivery challans, principal-job worker GST invoices and movement registers. Where the window has lapsed, voluntarily compute deemed supply value under Rule 28 and pay through DRC-03 with interest under Section 50; this voluntary disclosure is treated as a mitigating factor under Section 73(5).
Engineering
Common issue: Engineering job-work units under Section 65 audit face Section 143 read with Rule 45 ITC-04 quarterly compliance scrutiny. Goods sent by the principal manufacturer to the job worker beyond one year (inputs) or three years (capital goods) are deemed supplied on the original date; engineering units often delay ITC-04 disclosure and face cascading interest under Section 50.
How we handle it: File ITC-04 quarterly within the prescribed timeline (25 days from quarter end for aggregate turnover above ₹5 crore; half-yearly otherwise per Notification 35/2021-CT). Reconcile delivery-challan registers with job-worker GSTR-2A entries; for window-lapsed goods, compute deemed-supply value under Rule 28 and pay through DRC-03 voluntarily.
Plastics
Common issue: Plastic manufacturers under audit face HSN classification disputes between Chapter 39 primary forms (typically 18%) and Chapter 39 secondary moulded products (varying rates). Wrong HSN at REG-01 cascades into wrong-rate audit findings; the audit team frequently invokes Section 74 (fraud) framing rather than Section 73 where classification was clearly deliberate.
How we handle it: Obtain a contemporaneous classification opinion from a tax practitioner or seek an Advance Ruling under Section 97 for borderline HSN cases. Where classification was bona-fide but incorrect, voluntarily pay differential under DRC-03 to mitigate the Section 74 fraud framing; this typically converts the case to Section 73 with reduced penalty exposure.
Packaging
Common issue: Packaging units face Section 65 audits with dual-HSN classification scrutiny (paper-board Chapter 48 at 12% versus plastic Chapter 39 at 18%). Inverted-duty refund eligibility differs sharply between the two; misclassification at registration creates a cascading refund-recovery exposure where the audit team re-classifies outputs and disallows accumulated refunds.
How we handle it: Declare both HSN classifications in REG-01 amendment with the dominant product as primary; reconcile inverted-duty refund by HSN at year end. For mixed-output units, maintain SKU-wise HSN registers tied to GSTR-1 line-item disclosure; voluntarily revisit historical refund claims under the corrected HSN basis and disclose via DRC-03.
Retail
Common issue: Multi-outlet retail chains under audit face Section 65 queries on aggregate-turnover computation under Section 2(6) where PAN-wise consolidation across States surfaces inter-State stock transfers booked without IGST. Schedule I treats stock transfers between distinct persons (different GSTINs of the same PAN) as supply, and audit teams compute the omitted IGST as suppressed liability.
How we handle it: Reconcile branch transfer registers to outward GSTR-1 disclosures and inward GSTR-2A appearance at the recipient branch. Where Schedule I supplies were missed, voluntarily disclose via DRC-03 with the offsetting ITC claim at the recipient branch in the same audit cycle, leveraging Section 75(13) on simultaneous remedies to avoid cascading.

Bharti Airtel writEngineering services

Bharti Airtel rectification doctrine used to correct GSTR-3B at audit for a {{area_name}} engineering firm

Issue: An engineering firm in {{area_name}} discovered at the ADT-01 stage that an IGST and CGST swap of approximately three lakh forty thousand rupees in a single GSTR-3B period had not been correctable on the portal because the succeeding-period rectification route under Section 39(9) had lapsed.
Approach: We filed an Article 226 writ before the Madras High Court relying on the Supreme Court ratio in Union of India v Bharti Airtel for the principle that procedural limitations of the portal cannot defeat substantive correction. The petition prayed for a direction to permit DRC-03 correction with cross-credit adjustment.
Outcome: The Madras HC directed the proper officer to consider the DRC-03 representation; rectification was permitted within ninety days; the ADT-02 finding was withdrawn on this leg; cash flow remained neutral.
E-invoice IRNAuto components

E-invoice IRN reconciliation defended at audit for a {{area_name}} auto-components supplier

Issue: An auto-components Tier-2 supplier in {{area_name}} received an ADT-01 audit alleging a turnover suppression of approximately eighteen lakh rupees built on a comparison of IRNs generated on the Invoice Registration Portal against GSTR-1 outward supplies for a twelve-month window.
Approach: We reconstructed the IRN log against e-invoice cancellations within the twenty-four-hour window, mapped credit-note IRNs to negative outward supplies in GSTR-1, and reconciled the residual through the auto-population delta between IRP and GSTN. Notification 10/2023-Central Tax on the five-crore IRN threshold was placed on record for the relevant period.
Outcome: ADT-02 accepted the reconciliation; the eighteen lakh rupee suppression theory was dropped; a residual tax payment of approximately twenty-six thousand rupees on cancellation-window slippage was settled through DRC-03.
TRAN-1 transition creditEngineering services

Section 65 audit on transition credit defended for a {{area_name}} engineering firm

Issue: An engineering firm in {{area_name}} faced an ADT-01 audit on transition credit of approximately eight lakh rupees carried forward through TRAN-1 from the pre-GST regime, with the audit team contending that the credit was outside the Section 140 window for service tax accumulated credits.
Approach: We placed the Supreme Court ruling in Union of India v Filco Trade Centre Pvt Ltd on record for the principle that TRAN-1 windows are to be permitted in cases of genuine carry-forward, traced the underlying service-tax return ST-3 acknowledgements, and demonstrated compliance with the proviso conditions.
Outcome: ADT-02 accepted the transition credit; the eight lakh rupee reversal proposal was dropped; the credit was permanently reconciled to the electronic credit ledger.
Section 29 cancellationTrading

Section 65 audit on cancellation-effective-date defended for a {{area_name}} discontinued partnership firm

Issue: A discontinued partnership firm in {{area_name}} whose GSTIN was cancelled with retrospective effect received an ADT-01 audit covering the post-cancellation period, with a proposed deemed-supply demand of approximately eleven lakh rupees on alleged unreported supplies during the disputed retrospective window.
Approach: We placed Section 29(2) proviso on opportunity of hearing before retrospective cancellation, the Madras HC ruling on retrospective-cancellation discipline, and the actual cessation-of-business evidence including landlord receipts, employee F&F settlements and bank closure records. Section 36 retention obligations were acknowledged.
Outcome: ADT-02 accepted the genuine cessation; the cancellation effective date was prospectively rectified; the eleven lakh rupee deemed-supply demand was dropped; closure recorded through DRC-05.

Why these Ambattur Estate engagements look the way they do: For Ambattur Estate engagements specifically — the cluster of heavy manufacturing, auto components, engineering businesses that defines Ambattur Estate's commercial fabric; for Ambattur Estate units balancing production cycles with monthly GST and quarterly TDS compliance.

Common Questions

GST Audit Support FAQ — Ambattur Estate

Common questions from Ambattur Estate clients. Call 9566-068-468 for specific queries.

Yes. Section 66(6) requires the registered person to be given an opportunity of being heard on any material gathered in the special audit which is proposed to be used in any proceeding. After the report, if the proper officer initiates a Section 73 or 74 demand based on the findings, the registered person can contest the demand through the regular SCN-reply-adjudication-appeal route.
The Madras High Court in Tvl. Diya Agencies v. State Tax Officer (W.P. 16866/2023) and similar rulings have held that the recipient who has paid consideration with tax to the supplier and filed valid returns cannot be denied ITC merely because the supplier did not pay tax to the exchequer — provided Section 16 conditions are otherwise met. Audit teams cannot mechanically reverse ITC on this ground alone.
You can attempt it, but small errors in GST Audit Support often lead to notices, penalties or rejections that cost more to fix than to avoid. For Ambattur Estate clients we get it right the first time, which usually works out cheaper and far less stressful.
Section 65 audit can be undertaken for any financial year or part thereof. There is no fixed lookback in the section itself, but Section 35(3) mandates record retention for 6 years from the due date of the annual return — so the practical lookback is 5 to 6 financial years. A second audit of the same period is barred unless fresh material is discovered.
Yes. GST audit is GSTIN-wise — each registration has its own books, returns and assessment. A Tamil Nadu GSTIN of a multi-state business is audited separately from its Karnataka or Telangana GSTIN by the respective state's CGST or SGST authority. Records must therefore be maintained GSTIN-wise even where the underlying ERP is consolidated.
Your engagement is handled by our in-house team led by Ravivarman R (Founder, 15+ years, 500+ engagements), with M. E. Chokkalingam on compliance and S. Jayaprakash on GST matters. You deal with named, qualified people throughout your GST Audit Support — not a call centre.
Generally no. Once a Section 65 audit has been completed for a period and ADT-04 has been issued, that period cannot be re-audited under Section 65. Special audit under Section 66 is a distinct power and may be invoked separately if the Assistant Commissioner forms an opinion on incorrect valuation or excess credit. Re-opening a closed Section 65 audit requires fresh material and is exceptional.
Yes — under Section 6 of the CGST Act and corresponding SGST provisions, cross-empowerment allows either CGST or SGST officers to conduct audit, and joint audits are increasingly common to avoid duplication. Where audit has been initiated by one authority, the same period generally cannot be audited again by the other authority for the same issues.
Yes. Ambattur Estate sits squarely within the Chennai North area we serve every day, and we have handled GST Audit Support for heavy manufacturing and other clients across this part of Chennai. That local familiarity means fewer surprises for you.
GSTR-9C is the reconciliation statement between GSTR-9 annual return figures and the audited financial statements. From FY 2020-21 onwards, registered persons with aggregate turnover above ₹5 crore in a financial year must self-certify and file GSTR-9C alongside GSTR-9 by 31st December of the following year. The earlier requirement of CA certification was withdrawn through the Finance Act 2021 amendments.
Where the proper officer passes a demand order under Section 73(9) or 74(9) following an audit, the registered person can file an appeal under Section 107 to the Appellate Authority within 3 months (extendable by 1 month) along with a 10% pre-deposit of the disputed tax. Further appeals lie to the GST Appellate Tribunal under Section 112 once it is constituted.
A consultant who knows the Chennai North jurisdiction and how Ambattur Estate businesses operate moves faster and spots issues an online-only provider would miss. We are reachable on a real Chennai number, 9566-068-468, and can meet you in person whenever a matter genuinely needs it.
Section 66 allows an Assistant Commissioner (not below this rank) with prior approval of the Commissioner to direct a Chartered Accountant or Cost Accountant — nominated by the Commissioner — to audit a registered person where the officer is of the opinion that the value declared is not correct or the credit availed is not within the normal limits. The order is issued in ADT-03 and the auditor's report is submitted within 90 days, extendable by another 90 days.
Yes. The Madras High Court in Tvl. Raja Stores v. Assistant Commissioner (W.P. 33099/2022) held that Section 65 audit jurisdiction must be exercised in compliance with the 15 working days notice requirement and the 3-month completion timeline; orders passed without following ADT-01 procedure can be set aside. Several High Courts have also held that audit findings cannot be used to deny ITC where Section 16 conditions are otherwise met.
ADT-03 is the order under Section 66(1) directing a special audit by a nominated Chartered Accountant or Cost Accountant. ADT-01 in contrast is the Section 65 departmental audit notice issued before the proper officer commences audit. ADT-03 is therefore an order — not a notice — and the audit is conducted by an external professional, not departmental officers.
Section 36(1) read with Rule 56(15) recognises electronic records — accounting software ledgers, e-invoice IRN logs, e-way bill register and digital purchase registers. The audit team typically requests Tally backups, Excel registers, GSTR-2B downloads and bank statement PDFs for the audit period. Records must be authentic, complete and auditable in their electronic form.

Across Ambattur Estate we look after firms on Maya Street, Prithvipaakam Road, Sugal Street, Chennai - Tiruttani - Renigunta Road and Chennai Bypass as well as the Chennai Bypass Expressway, Pattaravakkam Bridge, Vanagaram - Ambathur - Puzhal Road and 2nd Main Road corridors — local GST Audit Support without the cross-city travel.
