Why FilingPro?

Why Iyyappanthangal Clients Choose FilingPro

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

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.

Section 66 Special Audit Coordination

Where Section 66 special audit is ordered via ADT-03, FilingPro liaises with the nominated CA, ensures full record access and tracks the 90-day report timeline (extendable by 90 days under Section 66(2)).

6-Year Records Retention Maintained

All audit working papers, GSTR-2B downloads, RCM workings and reconciliation sheets retained for 6 years from the due date of the annual return — meeting Section 36 read with Rule 56 record-retention obligations.

Section 107 First Appeal Filed

Where DRC-01 SCN escalates to a Section 73(9) or 74(9) demand order, Section 107 appeal is filed within 3 months with 10% pre-deposit. Personal hearing represented by qualified professionals.

Key Benefits

What Iyyappanthangal Clients Get

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

Multi-State GSTIN Audit Coordination
For Iyyappanthangal 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 Iyyappanthangal 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. Iyyappanthangal 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. Iyyappanthangal 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).

People Also Ask — GST Audit Support in Iyyappanthangal
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 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.

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.

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.

Section 65 departmental audit framework

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.

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

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

Section 66 special audit by CA / CMA

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.

Independence of Section 66 from prior audits or returns acceptance

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

ADT-01 intimation

Risk-engine selection and audit-pool composition

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

Form, contents and statutory basis

Form GST ADT-01 is the audit-initiation intimation prescribed under Rule 101(2) of the CGST Rules 2017. The form is generated by the proper officer (or audit officer authorised by the Commissioner) and served on the registered person at least fifteen working days before the date proposed for commencement of audit. ADT-01 contains the GSTIN and legal name of the registered person, the period proposed to be audited (typically one financial year), the place where audit will be conducted (place of business or office of the proper officer), the date of audit commencement, and a schedule of documents to be made available — books of account, invoices, returns including GSTR-9 and GSTR-9C, declarations, internal-audit reports, agreements material to the tax position, and any other document the audit team specifies. The fifteen-day window is a statutory taxpayer right under Section 65(3) read with Rule 101(2).

Responding to ADT-01 — documentation readiness

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

Glossary

Plain-English glossary for this service

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.

Special audit

Special audit is the audit ordered under Section 66 of the CGST Act where the officer not below the rank of Assistant Commissioner, having regard to the nature and complexity of the case and the interest of revenue, is of the opinion that the value has not been correctly declared or the credit availed is not within the normal limits. The audit is conducted by a chartered accountant or cost accountant nominated by the Commissioner.

ADT-01

ADT-01 is the statutory notice issued by the proper officer under sub-section (3) of Section 65 read with sub-rule (2) of Rule 101 informing the registered person of the institution of departmental audit. The notice must be served not less than fifteen working days prior to the conduct of audit and carries the period under audit, the place, the date and the records to be made available.

ADT-02

ADT-02 is the audit report under Section 65 communicated by the proper officer to the registered person within thirty days of conclusion of audit. It captures the findings of audit, the rights and obligations of the registered person, and the reasons for such findings. ADT-02 is the formal closure document of the departmental audit track.

ADT-03

ADT-03 is the direction issued under sub-section (1) of Section 66 read with sub-rule (1) of Rule 102 by which the proper officer, with prior approval of the Commissioner, directs the registered person to get his records examined and audited by a chartered accountant or cost accountant nominated by the Commissioner.

ADT-04

ADT-04 is the communication by the proper officer to the registered person of the findings of the special audit conducted under Section 66. It carries the observations of the nominee chartered accountant or cost accountant and the officer's view, and is the formal closure document of the special-audit track.

Nominee auditor

Nominee auditor is the chartered accountant or cost accountant nominated by the Commissioner under Section 66 to conduct the special audit. The registered person does not have a right to choose the nominee. The remuneration of the nominee is determined and paid by the Commissioner and such determination is final.

By Industry

Industry-specific patterns in Iyyappanthangal

How the local trade mix shapes this — Across Iyyappanthangal, the cluster of it services, residential, retail businesses that defines Iyyappanthangal's commercial fabric.

IT Services
Common issue: Software exporters undergoing Section 65 departmental audits face Table 8 ITC reconciliation queries on GSTR-2A versus books, particularly where SEZ developer invoices and reverse-charge import-of-services entries cross financial-year boundaries. The OECD International VAT/GST Guidelines treat exports as zero-rated under the destination principle, but the proper officer expects FIRC-realised consideration to tie back to invoice-month GSTR-1 disclosure within an audit-defensible bridge.
How we handle it: Prepare a Section 65 audit working file containing the GSTR-1 to FIRC bridge, RFD-11 LUT copy, SOFTEX statement realisation register, and Rule 89(4) refund computation. Map every GSTR-2A entry to vendor PAN and invoice number; preserve reverse-charge self-invoices under Section 31(3)(f) for the seven-year horizon in Section 36 read with Rule 56.
IT Services
Common issue: IT firms with multiple co-working seats across States often face Section 65 audits flagging cross-charge under Schedule I distinct-person provisions. Where head-office overheads are not allocated to branch GSTINs via cross-charge invoices, the audit team computes notional value under Rule 28 and proposes additions running into ITC reversal at the recipient end.
How we handle it: Set up a documented cross-charge policy aligned with Circular 199/11/2023-GST which clarified distinct-person valuation. Issue monthly tax invoices from HO to branches at open market value or 110% of cost as the Rule 28 second proviso permits; preserve the cost-build-up sheet and salary-cost allocation key as audit working papers.
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.
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.
Case Studies

Anonymised engagements we have handled

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

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.
E-way bill complianceCement transport

Section 65 audit on e-way bill compliance defended for a {{area_name}} cement transporter

Issue: A cement transporter in {{area_name}} received an ADT-01 audit on alleged e-way bill non-compliance under Rule 138 for inter-state movements of approximately fifty-six lakh rupees in value over a twelve-month window, with a proposed penalty under Section 129 of approximately ten lakh rupees.
Approach: We produced the e-way bill register, matched each consignment to the tax invoice, the transporter LR, and the recipient GRN. Where Part-B was generated late, the cure was demonstrated within validity. Section 129(3) penalty quantum was disputed on the documentary-completeness ground recognised in Madhya Pradesh HC rulings.
Outcome: ADT-02 confined the Section 129 penalty exposure to ninety-four thousand rupees on six consignments where Part-B was genuinely missing at interception risk; the bulk was dropped; the matter closed without DRC-01.
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.
Table 8 reconciliation cureIT Services

Table 8D adverse finding of ₹47 lakh cured before ADT-02 by re-running the 2B match

Issue: A Tidel Park IT-services company with ₹56 crore turnover was audited under Section 65 for FY 2021-22. The audit officer flagged a Table 8D negative of ₹47 lakh in the filed GSTR-9 and proposed in a draft observation note to demand reversal under Section 74 read with Rule 86A. The earlier consultant had filed Table 8 using auto-populated 8A without rebuilding from the underlying 2B and the difference looked like ineligible credit.
Approach: We requested a fifteen-day window to file a written reply before ADT-02 was issued — this pre-ADT-02 window under Section 65(6) read with the audit manual is where the cure has to happen, because once ADT-02 lands the matter moves to Section 73/74 proceedings. We rebuilt 8A from 2B for all twelve months, isolated ₹31 lakh of supplier invoices that the 2B export-limit truncation had dropped, identified ₹14 lakh of legitimate next-FY availment that belonged in 8C, and parked the residual ₹2 lakh in 8E with a working note.
Outcome: ADT-02 was issued without the Table 8 observation; only the ₹2 lakh residual was demanded under Section 73 (normal period, no penalty); the cure saved the client roughly ₹19 lakh in proposed interest and ₹47 lakh in proposed reversal; office rule was tightened — every GSTR-9 client now gets a 2B-rebuild working file before the partner signs the engagement.

Why these Iyyappanthangal engagements look the way they do: On the ground in Iyyappanthangal, the cluster of it services, residential, retail businesses that defines Iyyappanthangal's commercial fabric; for Iyyappanthangal IT-services firms managing export-LUT cycles alongside payroll and TDS.

Common Questions

GST Audit Support FAQ — Iyyappanthangal

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

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.
Generally no. Once a Section 65 audit has been completed for a period and ADT-04 has been issued, that period cannot be re-audited under Section 65. Special audit under Section 66 is a distinct power and may be invoked separately if the Assistant Commissioner forms an opinion on incorrect valuation or excess credit. Re-opening a closed Section 65 audit requires fresh material and is exceptional.
Yes. 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.
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.
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.
Turnaround depends on the service and how quickly you share documents. Once we have a complete set, GST Audit Support for Iyyappanthangal clients moves without avoidable delay, and we keep you posted at each stage. We give a realistic timeline upfront rather than an optimistic one.
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 Iyyappanthangal businesses the audit is conducted at the principal place of business so books, records and statutory registers can be inspected on-site.
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.
A consultant who knows the Chennai West jurisdiction and how Iyyappanthangal businesses operate moves faster and spots issues an online-only provider would miss. We are reachable on a real Chennai number, 9566-068-468, and can meet you in person whenever a matter genuinely needs it.
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.
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.
Our GST Audit Support fees are fixed and shared in writing before any work starts — no hourly billing and no surprises. Pricing depends on the complexity of your case, not your location, so Iyyappanthangal clients pay the same transparent rates as everyone else. See the pricing section above or call 9566-068-468 for an exact figure.
Where the proper officer passes a demand order under Section 73(9) or 74(9) following an audit, the registered person can file an appeal under Section 107 to the Appellate Authority within 3 months (extendable by 1 month) along with a 10% pre-deposit of the disputed tax. Further appeals lie to the GST Appellate Tribunal under Section 112 once it is constituted.
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.
Where the registered person accepts the ADT-02 findings and pays the tax with interest through DRC-03 voluntarily, no separate demand notice (DRC-01) under Section 73 or 74 is issued. The audit is closed in ADT-04. Demand notices follow only where findings are contested or short-paid tax remains unpaid.
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.
