Quick Answer

What is Form ADT-04 in Ambattur, Chennai?

ADT-04 is the audit closure or conclusion order under Rule 101(5). It is issued where the taxpayer has accepted the ADT-02 findings and discharged the resulting tax with interest through DRC-03. ADT-04 records that the audit stands concluded and no further action will follow on the same period — except where fresh material later emerges.

Why FilingPro?

Why Ambattur Clients Choose FilingPro

Expert GST Audit Support in Ambattur — qualified professionals, 15+ years experience, zero-penalty track record.

Section 17(5) Workings Pre-Disclosed

Motor vehicles for personal use, food and beverages, club memberships, works contract for immovable property and goods/services for personal use — all Section 17(5) blocked credits flagged and reversed in returns proactively.

RCM Register Reconstruction

Reverse charge on advocate fees, GTA, security services and director payments — register reconstructed for the audit period with cash payment evidence and ITC claim entries.

E-Invoice IRN Logs Reconciled

For Ambattur businesses above ₹5 crore AATO, IRN logs from the Invoice Registration Portal reconciled to GSTR-1 monthly — establishing compliance with mandatory e-invoicing from 1-Aug-2023.

ADT-02 Findings Replied With Case-Law

Where audit team proposes ITC reversal on supplier-default grounds or audit jurisdiction is exercised without proper notice, ADT-02 reply cites the Madras High Court rulings to defend the taxpayer's position.

DRC-03 Voluntary Closure

Where findings are accepted, voluntary payment via DRC-03 with reference to the audit ARN gets ADT-04 closure issued — no DRC-01 SCN under Section 73 or 74, no penalty escalation.

Key Benefits

What Ambattur Clients Get

Every GST Audit Support engagement delivers measurable, guaranteed outcomes — expert professionals, on time, every time.

Multi-State GSTIN Audit Coordination
For Ambattur headquartered businesses with branches outside Tamil Nadu, GSTIN-wise records produced at the principal place of business — joint CGST + SGST audit handled under one engagement.
GSTR-9C Self-Certification Without Surprises
For Ambattur businesses above ₹5 crore turnover, GSTR-9C reconciliation between audited financials and GSTR-9 prepared and self-certified well before 31 December — no Table 8 mismatch, no HSN summary gap.
Confidential Audit Defence
Audit working papers, ADT-02 findings and reconciliation evidence stored under access-controlled channels. Ambattur clients' audit data is never shared with third parties or used for cross-marketing.
Audit Closed Without Demand
Where findings are minor and accepted, voluntary payment via DRC-03 closes the audit at ADT-04 stage. Ambattur clients avoid DRC-01 SCN, Section 73/74 adjudication and penalty escalation.
ITC Defended Against Supplier Default
ITC questioned solely because the supplier did not pay tax to the exchequer is defended with Section 16 compliance evidence and Madras HC precedent — credits retained without reversal.
Table 8 Mismatch Demand Avoided
Table 8 of GSTR-9 — historically the most-litigated audit finding — prepared with line-item backup so audit team has no basis to propose ITC reversal under Rule 36(4) or Section 16(2)(aa).

GST Audit Support in Ambattur, Chennai 600053

Ambattur (PIN 600053) falls under the Ambattur Division of the Chennai North, the jurisdiction that handles statutory matters for businesses at this PIN. Ambattur is one of Chennai's largest industrial-residential zones, with thousands of small and medium engineering, auto-component and packaging units alongside dense residential growth. GST filings here typically involve B2B inter-state procurement, e-way bills and reverse-charge on transport. Businesses registered in Ambattur share the Chennai North jurisdiction, and their statutory matters route through the same Ambattur Division each time. We keep a cycle-by-cycle record of how the Ambattur Division of the Chennai North handles Ambattur filings and approvals.

Freight and foot traffic from the Ambattur Bus Terminus hub pull steady daily commerce through Ambattur, so there is rarely a quiet filing month in this industrial residential mixed pocket. Ambattur reads as a industrial residential mixed pocket with high commercial activity, anchored around Ambattur Lake and fed by the Ambattur Bus Terminus corridor. Ambattur sustains a high flow of commerce for a industrial residential mixed locality, and that flow is the raw material for the GST Audit Support files we close here. The industrial residential mixed mix of Ambattur shapes what lands in our workpapers — a blend of auto components activity and the commercial pulse around Ambattur Lake.

For a manufacturing business in Ambattur, the GST Audit Support scope is rarely generic; we tailor the checklist to how that sector actually transacts. Sector concentration matters: when Ambattur leans toward manufacturing, the GST Audit Support risks cluster around the same few line items each cycle. We have closed enough GST Audit Support files for manufacturing firms near Ambattur to know where the department usually probes. GST Audit Support for manufacturing businesses in Ambattur hinges on getting the sector's recurring entries right the first time.

Our Ambattur GST Audit Support process is built to be predictable, documented, and on time, cycle after cycle. Every GST Audit Support file we open for Ambattur is reconciled, reviewed by a qualified practitioner, and archived for seven years. Turnaround for Ambattur GST Audit Support is deterministic — fixed fee, a scoped timeline, and a same-business-day acknowledgement once filed. From the first GST Audit Support cycle, a Ambattur engagement is set up to be audit-ready rather than reconstructed under pressure later.

We treat Ambattur and Avadi as one catchment for GST Audit Support, which keeps documentation and turnaround consistent. Proximity to Avadi means a Ambattur engagement can extend across the locality cluster with no change in cadence. Serving Ambattur and Avadi from one team keeps GST Audit Support turnaround identical across the cluster. Coverage from Ambattur naturally extends to Avadi, so group entities across the area share one GST Audit Support workflow.

Sector signals in Ambattur — seasonal engineering swings and peak-period volumes — shape how we schedule GST Audit Support work. The longer we serve Ambattur, the more precisely we predict where a GST Audit Support file needs attention. Because we work repeatedly across Ambattur, we can benchmark a new client's GST Audit Support position against the locality norm. Common patterns in the Ambattur Division give Ambattur businesses an early-warning map we use to pre-empt GST Audit Support issues.

Incorporating in Ambattur comes with jurisdiction, registration and GST Audit Support steps that we sequence so nothing stalls the launch. Shifting principal place of business to Ambattur means updating jurisdiction to the Chennai North, and we manage the paperwork end-to-end. Relocating a registered office into Ambattur (PIN 600053) changes the assessing division, and we handle that GST Audit Support transition cleanly. New auto components ventures in Ambattur lean on us to stand up GST Audit Support correctly before the first deadline rather than after a notice.

People Also Ask — GST Audit Support in Ambattur
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 is the statutory record-retention horizon under GST?

Section 36 fixes the horizon at six years measured from the GSTR-9 due date for that year. Where any appeal, revision or proceeding remains pending, retention runs until one year after final disposal or six years, whichever event is later in time.

Can a second GST audit be conducted for the same period?

A second Section 65 audit of the same period is generally not undertaken absent fresh material. However, special audit under Section 66 may be ordered even where Section 65 audit was earlier conducted, and other proceedings under the Act remain available where conditions are met.

Does the audit have to take place at the taxpayer's premises?

Sub-section (1) of Section 65 allows the officer to elect between an on-premises audit and an office-of-the-officer audit. For most {{area_name}} taxpayers the on-site route is preferred so that books, statutory registers and electronic backups can be inspected together.

Is the audit unit the PAN or the individual registration number?

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.

What is the difference between ADT-02 and DRC-01?

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.

What is DRC-03 and when is it used after audit?

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.

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.

Post-audit options

SCN response and contested adjudication

Where one or more ADT-02 findings are disputed, the registered person prepares for the SCN under Section 73 or Section 74. The SCN response should be filed within thirty days of receipt of DRC-01; extensions are available under Section 73(8) or 74(8). The response should address each allegation with: (i) the factual position; (ii) the legal position with cited provisions and circulars; (iii) cited case law (Goetze, Bharti Airtel, Suncraft Energy, Aap and Co, GKN Driveshafts, Kranti Associates, Pradeep Goyal, Tapas Dutta — only where load-bearing); (iv) the quantum-mitigation argument (Section 73 versus Section 74 framing, limitation, computational errors). The personal-hearing under Section 75(4) is the consolidation step. The DRC-07 order then issues; first appeal under Section 107 follows for adverse outcomes.

Writ remedy before the Madras High Court

Where the ADT-02 findings, the SCN under Section 73/74, or the DRC-07 adjudication order suffers from jurisdictional infirmity — absence of Commissioner approval for Section 66 special audit, breach of Section 65(4) audit-completion timeline, denial of Section 75(4) opportunity of hearing, absence of Section 75(6) reasoned order, absence of DIN under Pradeep Goyal, breach of natural justice under audi alteram partem — the registered person can file a writ petition under Article 226 of the Constitution before the Madras High Court. The Aap and Co v UoI (Gujarat HC) and Asahi India Glass v UoI (P&H HC) line of authority offers guidance on writ entertainability in tax matters. The writ remedy is extraordinary and reserved for jurisdictional questions, not for merit-based challenges which belong in the statutory appellate hierarchy.

Settlement under Section 84 and amnesty schemes

Section 84 of the CGST Act provides for the continuance and validation of certain recovery proceedings; it does not provide a formal settlement scheme akin to the income-tax Settlement Commission framework which existed pre Finance Act 2021. However, the GST Council has periodically recommended amnesty schemes for specific compliance categories — Notification 03/2023-CT and the surrounding family of notifications on late-fee waiver, the GSTR-9 late-fee amnesty, the registration-revocation amnesty under Notification 03/2023-CT, and the periodic Sabka Vishwas (Legacy Dispute Resolution) Scheme equivalent for legacy excise / service tax cases. The registered person facing an adverse audit closure should monitor GST Council recommendations (47th Chandigarh, 50th, 53rd and subsequent meetings) for amnesty windows that may offer settlement at reduced penalty quantum. The OECD Forum on Tax Administration recognises amnesty-and-voluntary-disclosure programmes as compliance-architecture tools.

Section 65 departmental audit framework

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.

Audit completion timeline under Section 65(4)

Section 65(4) requires that the audit under Section 65 shall be completed within three months from the date of commencement of audit. The Commissioner is empowered to extend this period by a further six months for reasons recorded in writing; the maximum total audit-cycle is therefore nine months from commencement. 'Commencement of audit' is defined in the Explanation to Section 65(4) as the date on which records and 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. This definition is significant for the registered person — timely document submission tightens the audit timeline and prevents prolonged uncertainty; the OECD Forum on Tax Administration best-practice benchmarks similarly emphasise audit-cycle time as a taxpayer-rights consideration.

Section 66 special audit by CA / CMA

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.

Procedural sequence under Section 66(2) to 66(5)

Once the Section 66(1) opinion is formed and Commissioner's approval obtained, Section 66(2) requires the nominated Chartered Accountant or Cost Accountant to submit a report duly signed and certified, in such form as prescribed (Form ADT-04), within ninety days; this period can be extended by a further ninety days on application by the registered person or the CA/CMA, with the Commissioner's permission. Section 66(3) requires that the registered person be given an opportunity of being heard in respect of any material gathered on the basis of the special audit and proposed to be used in any proceeding against him. Section 66(4) clarifies that the expenses of the examination and audit, including remuneration of the CA/CMA, shall be determined and paid by the Commissioner. Section 66(5) preserves the proper officer's power to take further proceedings (SCN under Section 73 / 74) on the basis of the special audit findings.

What Ambattur clients usually ask next: On the ground in Ambattur, where SME engineering manufacturers handle dense inter-state procurement e-way bills reverse-charge on transport and high e-invoicing scrutiny; for Ambattur SME manufacturers managing complex GST input-tax-credit and inter-state compliance footprints.

Glossary

Plain-English glossary for this service

Terms you will hear in this area — Ambattur businesses operate where where SME engineering manufacturers handle dense inter-state procurement e-way bills reverse-charge on transport and high e-invoicing scrutiny.

Period of audit

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

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

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

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

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

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.

Reconciliation statement

Reconciliation statement is the document filed in Form GSTR-9C reconciling the value of supplies declared in the annual return with the audited annual financial statement. It also reconciles the tax payable as per the financial statement with the tax declared in the annual return and the input tax credit availed with the credit reflected in books.

DRC-01A

DRC-01A is the pre-show-cause-notice intimation prescribed under sub-rule (1A) of Rule 142. Part A is the officer's quantification of tax ascertained as payable on the basis of audit observations; Part B is the registered person's reply or acceptance. DRC-01A is the principal off-ramp before formal proceedings under Section 73 or 74.

DRC-03

DRC-03 is the voluntary-payment intimation prescribed under sub-rule (2) and (3) of Rule 142. It is filed where the registered person makes voluntary payment of tax, interest or penalty including pre-SCN deposit under Section 73(5) or 74(5). DRC-03 is the principal vehicle for closing out audit observations without formal adjudication.

Section 73(5) deposit

Section 73(5) deposit is the voluntary payment made by the registered person, on his own ascertainment or on ascertainment by the proper officer, before issuance of a show-cause notice. The deposit, when made along with applicable interest under Section 50, results in no penalty being leviable under Section 73(9).

Audit jurisdiction

Audit jurisdiction refers to the statutory authority of the Commissioner under sub-section (1) of Section 65 to authorise any officer to undertake audit of a registered person. Authorisation may be by general or specific order. A challenge to audit jurisdiction is typically agitated at the threshold under Article 226 before the High Court.

Section 67 search

Section 67 search is the enforcement-track action distinct from departmental audit. The proper officer not below the rank of Joint Commissioner, with reasons to believe that tax has been suppressed or credit wrongly availed with intent to evade tax, may authorise in writing any officer to inspect places of business and seize goods or documents.

By Industry

Industry-specific patterns in Ambattur

How the local trade mix shapes this — Ambattur businesses operate where where SME engineering manufacturers handle dense inter-state procurement e-way bills reverse-charge on transport and high e-invoicing scrutiny, and the dense engineering auto-component and packaging ecosystem of the Ambattur Industrial Estate operating across SIDCO and CMDA-developed sectors.

Manufacturing
Common issue: Small manufacturers in industrial estates undergoing audit struggle with Rule 56 stock-records adequacy. Rule 56(2) requires a true and correct account of production, raw materials, finished goods and waste, but many SMEs maintain only tally inventory without the legally required day-wise production register, opening the door to estimated-suppression additions under Section 73.
How we handle it: Reconstruct Rule 56(2) registers using Tally batch data, weighbridge slips and electricity-consumption normative ratios well before the ADT-01 intimation period closes. Bundle the reconstruction with a contemporaneous reconciliation note explaining the SOP gap; voluntary DRC-03 payment of any genuine differential closes the issue at audit stage rather than at SCN.
Manufacturing
Common issue: Manufacturers undertaking SEZ supplies under LUT face Section 65 audit scrutiny on Rule 96A timeline compliance for export realisation. Where SEZ payment realisation crosses fifteen months, the IGST recovery proposal under Rule 96A(1) provisos can be sizable, and the audit team often invokes interest under Section 50(1) from the original supply date.
How we handle it: Maintain a SEZ-LoA wise realisation tracker tied to RBI FIRC and SOFTEX certificates. For consignments exceeding fifteen months, file a representation citing the relaxations notified under various Notifications during FY 2020-21 (78/2020-CT etc.) and the GST Council 47th Chandigarh recommendations on realisation timelines.
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).
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.
Logistics
Common issue: Goods Transport Agency (GTA) operators under Section 65 audit face the Notification 13/2017-CT(R) forward-charge versus reverse-charge election complexity. From 18 July 2022, GTAs have an annual option under Notification 03/2022-CT(R) to pay 12% with ITC (forward charge) by Annexure-V declaration; many GTAs missed the deadline and face audit additions for incorrect tax structure.
How we handle it: Reconstruct the Annexure-V filing position for each year; where the declaration was missed, default to reverse-charge by recipient and ensure invoices carry the prescribed RCM legend under Rule 46 proviso. Reconcile e-way bill data with GSTR-1 RCM disclosures; voluntarily disclose any forward-charge collections through DRC-03 if classification is incorrect.

ADT-02 negotiationLogistics

Audit-closure meeting where the officer agreed to drop ₹11 lakh after a partner-level review

Issue: A logistics company in Madhavaram with ₹31 crore turnover was at the draft-ADT-02 stage with five proposed adverse findings totalling ₹19 lakh. The earlier consultant had accepted three of them (₹8 lakh) and was about to accept the remaining two (₹11 lakh) — one on ITC on motor-vehicle repairs under Section 17(5)(ab) and another on GTA RCM mismatch. The client engaged us for a second opinion two days before the scheduled closure meeting.
Approach: We re-examined both findings overnight. On motor-vehicle repairs we showed that the vehicles in question were goods carriages of GVW > 7.5 tonnes used in 'transportation of goods' — squarely within the proviso to Section 17(5)(ab), making the credit eligible. On the GTA RCM mismatch we reconciled GSTR-3B Table 3.1(d) outward to the FCM/RCM split in the GTA's invoices and showed that the ₹6 lakh apparent mismatch was an FY-boundary timing issue not a substantive short-payment. We requested a partner-led closure meeting with documentary backup.
Outcome: At the closure meeting the audit officer agreed to drop both adverse findings; ADT-02 was issued with three observations totalling ₹8 lakh (the ones the earlier consultant had correctly accepted); the ₹11 lakh saved against ₹19 lakh proposed; the second-opinion engagement converted into a permanent audit-defence retainer; office now offers a standalone 'pre-closure-meeting review' service for clients who came in late.
Suncraft EnergySteel fabrication

Suncraft Energy ratio used at ADT-02 reply for a {{area_name}} steel fabricator

Issue: A steel-fabrication unit in {{area_name}} received ADT-02 proposing reversal of approximately fourteen lakh rupees of input tax credit on the ground that four suppliers had defaulted in filing GSTR-1 on time, with the credit shown in GSTR-2A but not in the corresponding GSTR-2B for the recipient period.
Approach: The ADT-02 reply placed the Calcutta High Court ruling in Suncraft Energy Pvt Ltd v Assistant Commissioner squarely on record, produced bank statements, valid tax invoices and lorry receipts evidencing bona fide receipt of goods, and traced subsequent GSTR-1 filings of the suppliers showing that credit ultimately appeared on the portal.
Outcome: Demand confirmed at one lakh twelve thousand rupees on a single unrelated entry; the balance was dropped; first-appeal exposure was avoided; closure recorded through DRC-05.
Diya AgenciesHardware trading

Diya Agencies principle extended at Section 65 audit for a {{area_name}} hardware trader

Issue: A hardware-trading firm in {{area_name}} faced an ADT-01 audit covering two financial years with proposed credit reversal of approximately nine lakh rupees on supplier-side default. The audit team treated GSTR-2B absence as conclusive without testing the recipient's documentary trail.
Approach: We anchored the reply on the Madras High Court ratio in the Tvl Diya Agencies matter, which holds that supplier-side lapses cannot, in isolation, defeat recipient credit absent an enquiry against the supplier and a recorded finding on the recipient's good faith. Supplier-level enquiry trails and banking-channel payment evidence were filed.
Outcome: ADT-02 confined the reversal to seventy-eight thousand rupees relating to two genuinely missing suppliers; the residual eight lakh rupees was preserved; the matter closed within five months without DRC-01.
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.

Why these Ambattur engagements look the way they do: On the ground in Ambattur, the dense engineering auto-component and packaging ecosystem of the Ambattur Industrial Estate operating across SIDCO and CMDA-developed sectors; for Ambattur SME manufacturers managing complex GST input-tax-credit and inter-state compliance footprints.

Common Questions

GST Audit Support FAQ — Ambattur

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

ADT-04 is the audit closure or conclusion order under Rule 101(5). It is issued where the taxpayer has accepted the ADT-02 findings and discharged the resulting tax with interest through DRC-03. ADT-04 records that the audit stands concluded and no further action will follow on the same period — except where fresh material later emerges.
Form GST ADT-01 is the audit notice. Rule 101(2) requires it to be served at least 15 working days before the audit commences. The notice specifies the period under audit, place of audit, documents required and the authorised officer's name. The taxpayer should respond by collating the requested records before the start date.
Yes. The first discussion about your GST Audit Support requirement is free — call or WhatsApp 9566-068-468 and we will tell you honestly what is involved, what it costs, and the realistic timeline before you commit to anything.
ADT-02 is the audit findings report issued under Rule 101(5) at the conclusion of a Section 65 audit. It records the findings of the proper officer along with reasons, taxpayer's rights and obligations, and any short-paid tax, wrong ITC or interest detected. ADT-02 is not a demand notice but a finding — demand follows separately via DRC-01 if findings are not accepted and discharged.
Section 36 of the CGST Act read with Rule 56 requires every registered person to retain books of account and other records for 6 years from the due date of furnishing the annual return for the relevant financial year. Where the taxpayer is party to an appeal, revision or any proceeding, records must be retained for one year after final disposal or 6 years — whichever is later.
Call or WhatsApp 9566-068-468 with a one-line description of your requirement. We confirm exactly which documents your Ambattur case needs, share a fixed quote upfront, and start once you approve. The first discussion is free.
Section 65(1) gives the proper officer the power to conduct audit either at the place of business of the registered person or in the office of the proper officer. In practice for most Ambattur businesses the audit is conducted at the principal place of business so books, records and statutory registers can be inspected on-site.
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.
Our Maduravoyal office on Alapakkam Main Road (opposite KVB Bank) is well connected — from Ambattur, the Ambattur Bus Terminus is a handy reference point on the way. That said, GST Audit Support rarely needs a visit; most of it is done online.
Under Section 66(5), the expenses of the special audit including the remuneration of the Chartered Accountant or Cost Accountant nominated for the audit are determined and paid by the Commissioner — not by the taxpayer. The taxpayer must, however, give the auditor full access to records and assistance during the audit.
Yes. Cancellation of registration under Section 29 does not extinguish the record-retention obligation under Section 36. Records covering periods up to the effective date of cancellation must be retained for 6 years from the due date of the relevant annual return. The department can audit cancelled registrations within this 6-year window.
We review GST Audit Support work carefully before submission to avoid errors in the first place. If a genuine issue ever arises on something we filed for a Ambattur client, we help set it right — standing behind our work is part of the service.
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.
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.
Three reconciliations are pivotal — GSTR-1 vs GSTR-3B (outward supply consistency), GSTR-3B vs books (turnover and tax payment match), and GSTR-2B vs purchase register vs Table 8 of GSTR-9 (ITC eligibility). Variances are the most common audit findings, so these reconciliations should be prepared in advance and presented to the audit team in a documented format.
Rule 101 of the CGST Rules operationalises Section 65. Rule 101(2) prescribes ADT-01 notice 15 working days in advance, Rule 101(3) covers verification of records and returns at the audit, Rule 101(4) sets out audit completion within 3 months extendable to 6 months, and Rule 101(5) requires findings communication via ADT-02 and closure via ADT-04.
