Quick Answer

What happens if findings in ADT-02 are ignored in Thiruvottiyur, Chennai?

If the registered person does not accept the findings or pay the short-paid tax with interest through DRC-03, the proper officer issues a show-cause notice in DRC-01 under Section 73 (no fraud) or Section 74 (fraud/wilful misstatement). The taxpayer then has 30 days to file DRC-06 reply. Failing satisfactory reply, an adjudication order is passed under Section 73(9) or 74(9) creating demand.

People Also Ask — GST Audit Support in Thiruvottiyur
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.
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.

How much advance time does ADT-01 give the taxpayer to prepare?

Rule 101(2) prescribes a minimum buffer of fifteen working days from service of ADT-01 to the date when audit work actually starts. The buffer is used to organise records, reconcile returns and brief the authorised representative.

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.

Common audit findings

Place-of-supply errors and IGST versus CGST/SGST

Place-of-supply errors are the fourth common finding — typically where the registered person charged CGST/SGST (intra-State) when the place of supply under Sections 10 to 13 IGST Act was inter-State (requiring IGST), or vice versa. Section 77 of the CGST Act provides a corrective mechanism — where tax was paid under one head but is actually payable under another, the wrongly-paid tax can be claimed as refund and the correctly-payable tax should be paid; the registered person is not penalised, only interest under Section 50 may apply. Audit teams sometimes overlook Section 77 and compute full short-payment additions; citing Section 77 with documented evidence of the corresponding refund-eligible head closes the issue at audit stage.

ITC mismatch between GSTR-2A / 2B and GSTR-3B

The single most common Section 65 audit finding is ITC mismatch — ITC claimed in GSTR-3B Table 4(A) exceeding ITC available in GSTR-2A or GSTR-2B for the corresponding tax period. The post-2019 regulatory tightening — Rule 36(4) initially capping un-uploaded ITC at 20%, then 10%, then 5% (Notification 75/2019-CT, 49/2019-CT, 94/2020-CT trajectory), then Section 16(2)(aa) mandating GSTR-2B as the eligibility baseline (Notification 39/2021-CT effective 1 January 2022) — has progressively tightened the mismatch tolerance to nil. Audit findings on FY 2020-21 onwards typically computes the mismatch quarter-wise; the registered person's defence rests on vendor-wise reconciliation, vendor follow-up correspondence, and the Suncraft Energy bona-fide-buyer principle where applicable.

Reverse-charge under Sections 9(3) and 9(4) — self-invoice gaps

The second-most-common audit finding is missed reverse-charge — supplies where the recipient is liable to pay tax under Section 9(3) (notified categories — GTA without forward-charge election, legal services, sponsorship, services by directors, etc.) or Section 9(4) (supplies from unregistered to registered persons in notified categories for real-estate developers under Notification 07/2019-CT(R) read with 03/2019-CT(R)). Section 31(3)(f) requires the recipient to issue a self-invoice; many registered persons miss this step. The audit-team computes the missed output liability under reverse-charge, the corresponding ITC eligibility (subject to time-limit under Section 16(4)), and the interest under Section 50. Voluntary disclosure via DRC-03 is the standard close-out.

Pre-audit preparation

Engagement of representation counsel

For audits of even moderate complexity, engagement of a representation counsel — a Chartered Accountant with GST practice depth, or a tax advocate for procedural-rights-heavy cases — is the standard professional practice. The counsel's role is to mediate communication with the audit team, draft formal responses to audit observations, attend personal hearings, and prepare voluntary-disclosure computations where applicable. The Section 116 representation framework under the CGST Act permits authorised representatives — relatives, employees, advocates, Chartered Accountants, Cost Accountants, and Company Secretaries — to appear before the proper officer. The OECD Forum on Tax Administration documents counsel-engagement as a standard taxpayer-rights practice across mature tax jurisdictions.

Mock audit by independent reviewer

For high-stake audits (multi-year audits, Section 66 special audit nominations, audits of multi-State enterprises), a mock audit by an independent reviewer — typically a former tax-department officer or a senior Chartered Accountant with audit-defence experience — is a useful preparation step. The mock auditor replicates the audit-team's risk-engine-driven interrogation, identifies weak documentary positions, and recommends remedial steps. The cost of mock audits is justified where the potential audit exposure (tax plus interest plus penalty) materially exceeds the mock-audit fee. Comparative income-tax practice has long used mock-audits for high-stake Section 143(3) scrutiny assessments and Section 142(2A) special audits; the GST extension of this practice is recent but growing.

Document marshalling on receipt of ADT-01

Upon receipt of Form ADT-01, the registered person's first task in the fifteen-day window is structured document marshalling. The recommended sequence is: (i) compile the full year's GSTR-1, GSTR-3B, GSTR-2A / 2B downloads; (ii) compile GSTR-9 and GSTR-9C with the underlying reconciliation working papers; (iii) compile sales register, purchase register and stock register from the accounting system; (iv) compile bank statements and cash-book extracts; (v) compile e-way bill summaries; (vi) compile reverse-charge self-invoice register under Section 31(3)(f); (vii) compile Rule 42 / 43 ITC apportionment working papers; (viii) compile statutory audit and tax audit reports for the corresponding financial year. This structured marshalling enables the audit team to verify systematically and shortens the audit cycle materially.

Representation rights under Section 75

Multiple adjournments and Section 75(5)

Section 75(5) provides that the proper officer shall, if sufficient cause is shown by the person chargeable with tax, grant time to that person and adjourn the hearing for reasons to be recorded in writing; provided that no such adjournment shall be granted for more than three times to a person during the proceedings. The three-adjournment cap is a calibration between procedural fairness and proceeding-efficiency. In practice, registered persons facing complex audit findings should plan their adjournment requests strategically — use the first adjournment to gather documents, the second for representation-counsel engagement, and reserve the third for final consolidation. Beyond three adjournments, the proper officer is empowered to proceed ex-parte under Section 75(5) and pass the order on best-judgement basis.

Reasoned order requirement under Section 75(6)

Section 75(6) provides that the proper officer, in his order, shall set out the relevant facts and the basis of his decision. The reasoned-order requirement is a substantive procedural right that traces to the Kranti Associates v Masood Ahmed Khan (2010) Supreme Court principle on natural-justice-derived reasoned orders. Pradeep Goyal v UoI (Supreme Court on DIN — document identification number for all CBIC communications) supplements this by requiring procedural identifiability of the order. The registered person facing an order that does not engage with the response, does not cite the relevant provisions, or merely reproduces the SCN allegations, has strong grounds for either Section 107 first-appeal challenge or Article 226 writ challenge.

Bound-by-appellate-decisions principle under Section 75(11)

Section 75(11) provides that an issue on which the appellate authority or Appellate Tribunal or High Court has given its decision which is prejudicial to the interest of revenue in some other proceedings, and an appeal to the appellate authority or Appellate Tribunal or High Court or Supreme Court against such decision is pending, the period of stay shall be excluded in computing the limitation period. The provision permits the revenue to preserve its position pending appeal; the corresponding taxpayer protection is the principle that the proper officer is bound by appellate decisions on the same issue unless distinguished. Where the registered person can cite a binding precedent on the same issue from the Madras High Court or AAR Tamil Nadu, the proper officer is obliged to apply it.

Glossary

Plain-English glossary for this service

Terms you will hear in this area — In Thiruvottiyur, where industrial businesses dominate the local compliance profile.

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.

RCM register

RCM register is the internal ledger that tracks every transaction on which tax is payable under reverse charge by the recipient under Section 9(3) or 9(4) read with Notification 13/2017-CT, capturing GTA freight, legal fees, director sitting fees, security services, sponsorship and unregistered supplier purchases above thresholds.

Audit observation cure

Audit observation cure is the corrective workflow undertaken by the practitioner between the draft observation by the audit officer and issuance of formal ADT-02, by which a substantive demand position is reduced or eliminated through written submission, additional records, judicial precedent application and where appropriate voluntary DRC-03 payment.

Audit closure meeting

Audit closure meeting is the final sitting between the registered person and the audit officer where the contents of the draft ADT-02 are walked through, accepted positions are confirmed for voluntary payment and contested positions are flagged for the formal reply track, ahead of the officer signing and issuing ADT-02.

Principal place mismatch

Principal place mismatch is the practical situation where the registered person's principal place of business as declared in REG-06 differs from the location at which books of account are actually maintained, often resolved at audit commencement by treating the books-location as an additional place of business under Section 65(4) proviso.

Records reconstruction

Records reconstruction is the practitioner-led rebuilding of statutory registers under Rule 56 where the original electronic or physical records have been lost or corrupted, typically sourced from e-invoice portal IRN logs, banked-receipt trails, supplier statements and e-way-bill registers, with the reconstruction methodology disclosed in writing.

Departmental audit

Departmental audit is the audit conducted by the tax authorities under Section 65 of the CGST Act. The Commissioner or any officer authorised by general or specific order undertakes the audit at the place of business of the registered person or at the office of the proper officer. The substantive provision is Section 65 and the procedure is set out in Rule 101.

By Industry

Industry-specific patterns in Thiruvottiyur

How the local trade mix shapes this — In Thiruvottiyur, where industrial businesses dominate the local compliance profile; the business activity radiating outward from Tiruvottiyur Industrial Estate and nearby commercial pockets.

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.
Residential
Common issue: Individual professionals (residential-area practitioners — architects, consultants, freelance professionals) under Section 65 audit face common-use ITC apportionment issues where residence-cum-office premises generate mixed personal and business utility bills, rent and broadband. Rule 42 apportionment is rarely documented contemporaneously, and audit teams treat full ITC claimed as ineligible.
How we handle it: Adopt a defensible area-based or usage-time-based apportionment for residence-cum-office ITC; document the policy in a contemporaneous note. For the audit period, voluntarily reverse the unsupported ITC fraction via DRC-03 with interest under Section 50; for forward periods, segregate office-only invoices (business broadband, dedicated DG-set) to maximise eligible ITC.
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.
Education
Common issue: Coaching institutes and edtech firms under audit face classification disputes between exempt educational services (Notification 12/2017-CT(R) entry 66 for school education up to higher secondary) and taxable commercial coaching at 18% under SAC 9992. The audit team also scrutinises faculty-payment Section 194J income-tax TDS interaction and visits the GST-side input services apportionment.
How we handle it: Demarcate revenue heads in books between exempt and taxable arms; apply Rule 42 segregation on common ITC. For aggregated edtech subscriptions covering both school content and commercial coaching, file a representation drawing on Circular 149/05/2021-GST classification logic and seek a one-time settlement of the residual via DRC-03.
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.
Case Studies

Anonymised engagements we have handled

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

A flavour of cases we handle nearby — In Thiruvottiyur, where industrial businesses dominate the local compliance profile.

Section 34 credit-noteConsumer electronics

Section 65 audit on credit-note disclosure defended for a {{area_name}} consumer electronics distributor

Issue: A consumer electronics distributor in {{area_name}} received an ADT-01 audit on alleged non-disclosure of Section 34 credit notes of approximately twenty-nine lakh rupees in GSTR-1 within the September-following outer date, with a proposed deemed-supply demand of approximately five lakh twenty thousand rupees.
Approach: We mapped each credit note against the recipient acknowledgement of ITC reversal under Section 34(2) proviso, demonstrated that the recipient had reversed the credit in the corresponding GSTR-3B, and showed that the supplier-side credit note adjustment was therefore permitted. Original tax invoices and recipient confirmations were filed.
Outcome: ADT-02 accepted the credit-note treatment; the five lakh twenty thousand rupee demand was dropped; the recipient-acknowledgement template was rolled forward as standard practice.
Section 15(3) discountsConsumer durables

Section 65 audit on Section 15(3) discount treatment defended for a {{area_name}} consumer durables seller

Issue: A consumer durables seller in {{area_name}} received an ADT-01 audit on alleged non-deduction of post-supply discounts of approximately twenty-two lakh rupees from taxable value, with a proposed differential tax demand of approximately three lakh ninety-six thousand rupees.
Approach: We mapped each post-supply discount against the Section 15(3)(b) twin condition of pre-supply agreement linkage and recipient ITC reversal proof. Recipient credit-note acknowledgements and the underlying dealership agreement were filed. CBIC Circular 92/11/2019 on discounts and Circular 105/24/2019 (subsequently rescinded) were placed in context.
Outcome: ADT-02 accepted the discount treatment; the three lakh ninety-six thousand rupee differential was dropped; the dealership agreement clauses were tightened to capture future discount-conditions formally.
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.

Why these Thiruvottiyur engagements look the way they do: For Thiruvottiyur engagements specifically — the cluster of industrial, petrochemicals, port-adjacent businesses that defines Thiruvottiyur's commercial fabric; for Thiruvottiyur units balancing production cycles with monthly GST and quarterly TDS compliance.

Common Questions

GST Audit Support FAQ — Thiruvottiyur

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

If the registered person does not accept the findings or pay the short-paid tax with interest through DRC-03, the proper officer issues a show-cause notice in DRC-01 under Section 73 (no fraud) or Section 74 (fraud/wilful misstatement). The taxpayer then has 30 days to file DRC-06 reply. Failing satisfactory reply, an adjudication order is passed under Section 73(9) or 74(9) creating demand.
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.
Delays in statutory work can mean penalties, interest or blocked services that usually cost far more than acting on time. For Thiruvottiyur clients we track the relevant due dates and remind you in advance so GST Audit Support stays on schedule. Call 9566-068-468 if you suspect you have already missed a deadline.
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).
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.
Yes, we regularly take over part-completed GST Audit Support work. Share what has been done so far on WhatsApp 9566-068-468 and we will review it, point out anything that needs correcting, and continue from where you are.
Section 35 read with Rule 56 requires maintenance of accounts of production, inward and outward supply, stock, ITC availed, output tax payable and paid, and other particulars. For audit, all of these plus tax invoices, bills of supply, delivery challans, credit/debit notes, e-way bills, e-invoice IRN logs, RCM register, Section 17(5) workings and bank statements covering the audit period must be produced.
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.
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.
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.
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.
Yes. Thiruvottiyur has an active base of residential and allied businesses, and we regularly handle GST Audit Support for exactly these kinds of clients. We tailor the approach to your line of work rather than applying a one-size template.
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.
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.
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.
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.
