Is there a separate rule governing special audit in T Nagar, Chennai?

Yes. Rule 102 of the CGST Rules deals with special audit under Section 66. Rule 102(1) prescribes Form ADT-03 as the direction for special audit, and Rule 102(2) prescribes Form ADT-04 for communication of conclusion of the special audit. Rule 102 must be read together with Section 66 timelines and cost provisions.

GST Audit Support in T Nagar, Chennai 600017

Records we prepare for T Nagar carry the geo-zone 600xx tag and coordinates 13.0418, 80.2341, which map each submission back to this locality. Statutory correspondence for T Nagar businesses routes through the Saidapet Division, so we align every GST Audit Support engagement to that jurisdiction from the start. We keep a cycle-by-cycle record of how the Saidapet Division of the Chennai South handles T Nagar filings and approvals. The 600xx geo-zone covering T Nagar groups several locality clusters under common administration, keeping documentation expectations predictable.

The businesses clustered around Panagal Park in T Nagar drive the bulk of the GST Audit Support workload we see each cycle. Freight and foot traffic from the Mambalam Suburban Railway hub pull steady daily commerce through T Nagar, so there is rarely a quiet filing month in this largest textile and jewellery retail in india pocket. Document pickup near Panagal Park is a same-hour errand for our T Nagar engagements rather than the half-day a typical Chennai client expects. The largest textile and jewellery retail in india mix of T Nagar shapes what lands in our workpapers — a blend of textile retail activity and the commercial pulse around Panagal Park.

GST Audit Support for hospitality businesses in T Nagar hinges on getting the sector's recurring entries right the first time. Sector concentration matters: when T Nagar leans toward hospitality, the GST Audit Support risks cluster around the same few line items each cycle. Mixed hospitality activity across T Nagar means our GST Audit Support team keeps sector playbooks ready rather than improvising per client. The hospitality firms we serve in T Nagar value a GST Audit Support partner who already understands their sector's compliance rhythm.

The qualified-review step on every T Nagar GST Audit Support file is where errors get caught before they reach the portal. Every GST Audit Support file we open for T Nagar is reconciled, reviewed by a qualified practitioner, and archived for seven years. A T Nagar client sees the same GST Audit Support cadence each cycle: intake, reconciliation, review, filing, acknowledgement. From the first GST Audit Support cycle, a T Nagar engagement is set up to be audit-ready rather than reconstructed under pressure later.

A client relocating between T Nagar and Kodambakkam keeps the same GST Audit Support file and the same team. From the same T Nagar team we also serve Kodambakkam and other nearby localities without re-onboarding clients. Businesses straddling T Nagar and Kodambakkam get a single GST Audit Support point of contact rather than two. Serving T Nagar and Kodambakkam from one team keeps GST Audit Support turnaround identical across the cluster.

Over several cycles in T Nagar, the recurring GST Audit Support issues cluster around a predictable short list we screen for early. Sector signals in T Nagar — seasonal retail swings and peak-period volumes — shape how we schedule GST Audit Support work. Because we work repeatedly across T Nagar, we can benchmark a new client's GST Audit Support position against the locality norm. The longer we serve T Nagar, the more precisely we predict where a GST Audit Support file needs attention.

We onboard new T Nagar entities onto a GST Audit Support cadence that is audit-ready from the very first cycle. When a Teynampet business expands into T Nagar, we extend its GST Audit Support setup to PIN 600017 without disruption. Relocating a registered office into T Nagar (PIN 600017) changes the assessing division, and we handle that GST Audit Support transition cleanly. Incorporating in T Nagar comes with jurisdiction, registration and GST Audit Support steps that we sequence so nothing stalls the launch.

People Also Ask — GST Audit Support in T Nagar
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 Form ADT-04?

Form ADT-04 is the order conveying the special audit report to the registered person under Rule 102, marking the conclusion of the Section 66 process. Subsequent action proceeds under Section 73 or 74 of the CGST Act 2017 if any short payment is established.

Can audit findings under ADT-02 lead directly to Section 74 proceedings?

Yes, but Section 74 requires recorded satisfaction of fraud, wilful misstatement or suppression of facts. Where ADT-02 findings rest on tabular variance alone without these ingredients, the proceedings are vulnerable to downgrade to Section 73 on Kranti Associates speaking-order grounds.

What is the pre-deposit for Section 107 appeal against an audit-led demand?

Section 107(6) requires pre-deposit of ten per cent of the disputed tax leg only. The Madras High Court ratio in Tvl Sri Murugan Trading confines the obligation to disputed tax, leaving interest and penalty components outside the pre-deposit computation.

Can the registered person request rescheduling of an ADT-01 audit visit?

Yes. A written request citing genuine reasons such as auditor unavailability, partner illness or pendency of board records reconciliation is generally accommodated by the proper officer, provided the rescheduling does not breach the three-month completion window under Section 65(4).

Is e-way bill data tested during a Section 65 audit?

Yes. The e-way bill register under Rule 138 is reconciled with outward supplies in GSTR-1 and inward consignment receipts. Audit teams flag Part-B late generation, validity-period breaches and consignor-consignee GSTIN mismatches as potential Section 129 exposures.

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.

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.

Glossary

Plain-English glossary for this service

ADT-02 closure

ADT-02 is the form in which the proper officer communicates the audit findings, rights and obligations to the registered person within thirty days of completion of the audit; observations in ADT-02 typically feed into a subsequent Section 73 or Section 74 demand notice if tax has not been voluntarily paid.

ADT-03 direction

ADT-03 is the direction issued under Section 66(1) by the Commissioner to a registered person requiring submission to special audit by a nominated chartered or cost accountant; the audit report is to be submitted within ninety days extendable by another ninety days for sufficient cause.

Audit period

Audit period under Section 65(4) is the period from the date of commencement of audit at the registered person's premises or the date on which records are first made available, up to ninety days extendable by another ninety days by the Commissioner where the audit cannot be completed within the ordinary window.

Pre-ADT-02 window

Pre-ADT-02 window is the practical window between draft observation by the audit officer and issuance of formal ADT-02, during which the registered person can file a written reply, produce additional records and make voluntary DRC-03 payments under Section 73(5) to avoid penalty exposure.

Rule 56 records

Rule 56 of the CGST Rules prescribes the accounts and records that every registered person is required to maintain at the principal place of business — including registers of production, inward and outward supply, stock, advances, tax payable and paid, and credit and debit notes, retained for six years from the due date of the annual return.

Six-year retention

Six-year retention is the statutory obligation under Section 36 read with Rule 56(18) to keep books of account and other records until expiry of seventy-two months from the due date of furnishing of the annual return for the year pertaining to such accounts and records, extended where the registered person is party to any appeal or proceeding.

Records walkthrough

Records walkthrough is the practitioner-led structured presentation of statutory registers, reconciliations and working notes to the audit officer at the commencement of audit, designed to substitute an unstructured document-request cycle and reduce overall audit duration.

Adverse finding

Adverse finding is an observation in the audit officer's draft note or in the formal ADT-02 alleging short-payment of tax, excess availment of input tax credit, wrong claim of refund or other contravention, carrying with it a subsequent demand under Section 73 or Section 74 if the tax with interest is not voluntarily paid.

Voluntary DRC-03

Voluntary DRC-03 is a payment of tax with interest made by the registered person on his own ascertainment under Section 73(5) or Section 74(5), filed in Form DRC-03 on the common portal, with the procedural advantage that no penalty under Section 73(9) or reduced penalty under Section 74(5) applies if the payment is made before issuance of notice.

Table 8 reconciliation

Table 8 reconciliation is the working file built between the auto-populated GSTR-2A or 2B based ITC in Table 8A of GSTR-9 and the ITC availed and reported by the registered person in Table 8B and 8C, with the residual variance disclosed in Table 8D and an explanation parked in Table 8E or 8F.

Audit-readiness pack

Audit-readiness pack is the practitioner-prepared bundle delivered to the audit officer at commencement, typically containing turnover reconciliation, ITC reconciliation, RCM register, blocked credit working under Section 17(5), and a self-identified list of likely adverse findings with cure positions.

Block credit register

Block credit register is the internal ledger maintained by the registered person under good-practice (not statutorily prescribed) listing every input tax credit availed and separately the credits blocked under Section 17(5) categories such as motor vehicles, food and beverages, club memberships and personal consumption, with rationale.

By Industry

Industry-specific patterns in T Nagar

How the local trade mix shapes this — T Nagar businesses operate where the cluster of textile retail, jewellery, hospitality businesses that defines T Nagar's commercial fabric.

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.
Hospitality
Common issue: Hotel and restaurant chains face Section 65 audit issues on the dual-rate restaurant scheme (5% without ITC versus 18% with ITC for specified non-standalone restaurants per Notification 11/2017-CT(R) as amended). Mid-year scheme-switching, or restaurants within hotels charging room tariff above ₹7,500 per day, frequently leads to ITC eligibility disputes.
How we handle it: Maintain a daily room-tariff register evidencing the ₹7,500 threshold determination month-wise; lock in the restaurant scheme at financial-year start and avoid intra-year switching. For aggregator (Zomato/Swiggy) supplies under Section 9(5), reconcile aggregator-collected output GST against own GSTR-1 disclosure to avoid double-counting allegations.
Jewellery
Common issue: Jewellers under Section 65 audit face Rule 56(18) stock-register adequacy scrutiny — daily quantity-wise opening, additions, deductions and closing stock entries are mandated for precious metals and stones. Many family-run jewellers maintain only sale-bill registers, and the audit team computes notional value under Rule 28 for unreconciled stock differences.
How we handle it: Reconstruct Rule 56(18) registers using purchase bills, hallmarking-centre receipts, BIS-licence batch traces and karigar challans. Reconcile to the income-tax-side stock-statement filed in audited accounts; voluntarily disclose any genuine differential through DRC-03. Capture TCS under Section 206C(1F) at 1% above ₹2 lakh in parallel income-tax compliance.
Restaurants
Common issue: Restaurant operators on Zomato / Swiggy face Section 65 audit issues on Section 9(5) e-commerce-operator collection — from 1 January 2022 (Notification 17/2017-CT(R) amendment by Notification 17/2021-CT(R)), the aggregator collects 5% GST on behalf of the restaurant. Restaurants frequently double-disclose the same revenue in GSTR-1 leading to audit-stage reconciliation issues.
How we handle it: Reconcile aggregator settlement reports (Zomato MIS, Swiggy partner statements) to restaurant GSTR-1 disclosures; ensure Section 9(5) supplies are reported under the prescribed table without duplicating output. Maintain a daily aggregator-versus-own-channel revenue split; for own-channel (dine-in, takeaway, telephone) revenue, capture in GSTR-1 directly at 5% without ITC.
Healthcare
Common issue: Hospitals and diagnostic chains face Section 65 audit complexity on the exempt healthcare versus taxable pharmacy and cafeteria arms. Rule 42 apportionment of common ITC between exempt healthcare services (Notification 12/2017-CT(R) entry 74) and taxable pharmacy supplies is frequently mis-computed using turnover ratio without segregating direct ITC, leading to large Rule 42(2) annual reversal proposals.
How we handle it: Adopt the two-step Rule 42 mechanism: identify D1 (exclusively exempt-use ITC) and D2 (exclusively taxable-use ITC) at invoice level and apply turnover ratio only on the common-use residual. Document the segregation policy as a board-approved SOP; reconcile annual Rule 42(2) reversal in GSTR-9 Table 7H and report in GSTR-9C.
Case Studies

Anonymised engagements we have handled

Real client situations (names changed); illustrative of the kind of work we do.

GSTR-9C defenceHospitality

GSTR-9C reconciliation defended at audit for a {{area_name}} hospitality group

Issue: A hotel group in {{area_name}} above the five-crore aggregate turnover threshold filed GSTR-9C with a turnover reconciliation difference of approximately seven lakh rupees explained as unbilled revenue. The ADT-01 audit team proposed treating the entire difference as suppressed taxable turnover with tax of approximately one lakh twenty-six thousand rupees.
Approach: We anchored the reply on Section 13(2) time-of-supply and demonstrated that the unbilled revenue was an accounting accrual recognised under Ind AS 115 but not a supply within Section 7(1) at the cut-off. Audited financials, room-occupancy registers and the subsequent period invoices were tied line-by-line.
Outcome: ADT-02 accepted the reconciliation; no tax demand was raised on the unbilled revenue head; the matter closed without DRC-01 escalation; turnover reconciliation discipline was carried into the next year.
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.
Section 74 downgradeJewellery

Section 73 SCN downgrade from Section 74 secured at audit close for a {{area_name}} jeweller

Issue: A jeweller in {{area_name}} faced an ADT-02 transitioning into a Section 74 SCN of approximately twenty-six lakh rupees on alleged suppression evidenced by GSTR-1 versus GSTR-3B output variance, without recorded satisfaction of the fraud limb beyond a portal-driven tabular delta.
Approach: We invoked the Kranti Associates v Masood Ahmed Khan requirement of a speaking foundation for any quasi-judicial action and the GKN Driveshafts (India) Ltd v ITO framework for testing jurisdictional satisfaction. The reply demonstrated through audited financials that the variance was a credit-note timing offset.
Outcome: The adjudicating officer dropped Section 74 and confirmed demand under Section 73 with ten per cent penalty rather than hundred per cent; final exposure of approximately twenty-eight lakh rupees was settled on the reduced penalty footing.
Section 107 first appealRestaurants

Section 107 first appeal filed against an adverse ADT-02 demand for a {{area_name}} restaurant chain

Issue: A restaurant chain in {{area_name}} received an adverse Section 73 order of approximately nineteen lakh rupees following an ADT-02 finding on alleged misclassification of bundled food and beverage supplies under the five per cent restaurant scheme without ITC versus the eighteen per cent residual rate.
Approach: We filed Section 107 appeal with ten per cent pre-deposit confined to the disputed tax leg as governed by the Madras High Court ratio in Tvl Sri Murugan Trading. The grounds anchored on Notification 11/2017-Central Tax (Rate) as amended by Notification 13/2018, the AAAR ruling in Coffee Day Global on restaurant supplies, and the menu-card composition evidence.
Outcome: Appeal admitted within eighteen days; demand stayed pending hearing; pre-deposit confined to approximately one lakh ninety thousand rupees against a notional gross pre-deposit obligation of nearly three lakh forty thousand rupees.

Why these T Nagar engagements look the way they do: Closer to T Nagar, the cluster of textile retail, jewellery, hospitality businesses that defines T Nagar's commercial fabric, which is why for T Nagar businesses balancing growth ambitions with tight statutory compliance.

Common Questions

GST Audit Support FAQ — T Nagar

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

Yes. Rule 102 of the CGST Rules deals with special audit under Section 66. Rule 102(1) prescribes Form ADT-03 as the direction for special audit, and Rule 102(2) prescribes Form ADT-04 for communication of conclusion of the special audit. Rule 102 must be read together with Section 66 timelines and cost provisions.
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.
No. The GST Audit Support fee we quote upfront is the fee you pay — any government fees or third-party charges are shown separately and explained in advance. T Nagar clients get full transparency before committing.
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.
Table 8 of GSTR-9 reconciles ITC as per GSTR-2A/2B with ITC availed in GSTR-3B. Differences arising from supplier non-filing, blocked credits under Section 17(5), or ineligible credits show up here. Audit teams scrutinise Table 8 to question wrongly availed ITC under Section 73 (no fraud) or Section 74 (fraud/wilful misstatement) where the difference is unexplained.
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 T Nagar client, we help set it right — standing behind our work is part of the service.
Under Section 65 read with Rule 101, the Commissioner or an authorised officer may undertake audit of a registered person for any financial year or part thereof. ADT-01 notice is issued at least 15 working days before commencement. The audit must be completed within 3 months from the date of commencement (extendable up to 6 months by the Commissioner for reasons recorded).
Section 65 audit is conducted at the principal place of business as registered in REG-06. If the audit covers transactions of branches (additional places of business), the records of those branches must be produced at the principal place or made accessible to the audit team. T Nagar businesses with branches outside Tamil Nadu must coordinate branch records to the audit venue.
Turnaround depends on the service and how quickly you share documents. Once we have a complete set, GST Audit Support for T Nagar clients moves without avoidable delay, and we keep you posted at each stage. We give a realistic timeline upfront rather than an optimistic one.
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.
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. We handle GST Audit Support for salaried individuals, proprietors, partnerships, LLPs and private limited companies across T Nagar. Whatever your structure, we scope the GST Audit Support work to fit it — call 9566-068-468 to discuss yours.
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.
Recurring findings include — ITC mismatch between GSTR-2B and GSTR-3B, Section 17(5) blocked credits wrongly availed (motor vehicles for personal use, food and beverages, club memberships), RCM not paid on advocate fees and GTA, e-way bill missing for consignments above ₹50,000, e-invoice non-compliance for taxpayers above ₹5 crore AATO, HSN summary errors in GSTR-1 Table 12, and Schedule III adjustments not made for related-party transactions.
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.
Where the taxpayer accepts the findings in ADT-02, the short-paid tax along with interest under Section 50 (and any applicable penalty) is voluntarily paid through Form DRC-03 on the GST portal. Reference to the audit ARN is recorded in DRC-03. The proper officer then passes the closure order in ADT-04 noting that the matter has been settled.
