Quick Answer

What is the audit period under Section 65 in West Mambalam, Chennai?

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.

People Also Ask — GST Audit Support in West Mambalam
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-03 in GST?

Form ADT-03 is the order issued under Section 66(1) directing a Commissioner-nominated Chartered Accountant or Cost Accountant to conduct a special audit. It is an order, not a notice, and the nominated professional then conducts the audit on the department's behalf.

Within how many months must a Section 65 audit be completed?

Section 65(4) requires completion within three months from the date of commencement. The Commissioner may extend the period by a further six months for reasons recorded in writing, taking the outer limit to nine months in extended cases.

What is the time limit for a Section 66 special audit report?

Section 66(2) requires the nominated Chartered Accountant or Cost Accountant to submit the audit report within ninety days. The period is extendable by another ninety days on application by the auditor or on the department's own motion for sufficient reasons.

Who bears the auditor's professional fee under Section 66?

Under Section 66(5) the Commissioner determines and discharges the remuneration of the nominated Chartered Accountant or Cost Accountant. The registered person carries no fee burden for the special-audit professional, although internal representation costs remain to the taxpayer's account.

Has GSTR-9C self-certification continued to apply for the financial years since 2020-21?

Yes. Beginning the 2020-21 financial year, taxpayers crossing the five-crore aggregate-turnover mark in any year self-certify the reconciliation statement. Earlier external certification by a Chartered Accountant was dispensed with by the Finance Act 2021 amendments to Section 44.

What is the GSTR-9C turnover threshold from FY 2020-21?

The threshold is aggregate turnover above five crore rupees in the financial year, applied PAN-wise across all GSTINs. Persons below this threshold are not required to file GSTR-9C even where GSTR-9 filing is otherwise compulsory for them.

What West Mambalam clients want to know before signing: On the ground in West Mambalam, on the T Nagar-Kodambakkam corridor that passes through West Mambalam.

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.

ADT-02 audit report

Reading the audit-observations and proper-officer reasoning

ADT-02 audit observations are structured around the verification heads — turnover under Section 9 read with Section 7, taxable value under Section 15, rate of tax under the rate notifications, ITC under Sections 16 to 21, refund under Sections 54 and 55, and miscellaneous compliance. Each observation typically includes the audit team's working, the discrepancy quantum, the section / rule under which the proposed addition is framed, and the proper officer's reasoning. The Kranti Associates v Masood Ahmed Khan (2010) Supreme Court principle on reasoned orders applies — the proper officer's reasoning must engage with the registered person's explanations and cannot be a mechanical reproduction of audit-team working. Where reasoning is absent or perfunctory, the registered person has stronger grounds in subsequent Section 73 / 74 proceedings or in a writ petition before the Madras High Court under Article 226.

Voluntary payment under Section 73(5) post ADT-02

Section 73(5) of the CGST Act allows the registered person to pay the tax along with interest under Section 50 on the basis of own ascertainment or as ascertained by the proper officer and inform the proper officer of such payment in Form DRC-03 before service of an SCN under Section 73(1). Where the registered person agrees with the ADT-02 findings, voluntary payment under Section 73(5) avoids the SCN cycle entirely and limits the financial impact to tax plus interest, without penalty. Section 73(6) then mandates that no SCN shall be issued in respect of the amount paid. This voluntary-payment route is the preferred audit-closure mechanism for genuine ITC errors, classification mis-applications and minor valuation gaps, and is widely used in practice.

Disagreement options post ADT-02

Where the registered person disagrees with one or more ADT-02 findings, the response options are: (a) file a Section 75 representation seeking re-consideration before the SCN stage; (b) await the SCN under Section 73 or 74 and contest at that stage; (c) where the audit findings are perceived as jurisdictionally infirm, file a writ petition before the Madras High Court under Article 226 of the Constitution. The writ remedy is typically reserved for jurisdictional infirmities — absence of Commissioner approval under Section 66, breach of the Section 65(4) timeline, denial of Section 75 opportunity of hearing — rather than for merit-based challenges. The Aap and Co v UoI (Gujarat HC) and Asahi India Glass v UoI (P&H HC) lines of authority offer guidance on writ-jurisdictional questions in audit and assessment matters.

ADT-03 cost recovery

Statutory basis under Section 66(4) and Rule 102

Form GST ADT-03 is the cost-recovery determination notice under Rule 102 of the CGST Rules read with Section 66(4) of the CGST Act. Section 66(4) provides that the expenses of the examination and audit of records under Section 66, including remuneration payable to the Chartered Accountant or Cost Accountant nominated by the Commissioner, shall be determined and paid by the Commissioner; ADT-03 is the form through which this determination is communicated to the registered person, and the amount becomes payable as a Government dues recovery under Section 79. The Rule 102 framework was added to provide procedural clarity on the cost-recovery mechanism; comparative pre-GST excise (Section 14A Central Excise Act, since omitted) and service tax (Section 72A Finance Act 1994) had similar cost-recovery features.

Determination of remuneration and challenges

The Commissioner determines the remuneration of the nominated Chartered Accountant or Cost Accountant under Section 66(4) based on rates broadly aligned with the ICAI and ICMAI minimum recommended scales for special-audit work. The registered person typically has no direct say in either the selection of the CA/CMA or the remuneration determination — both are administrative decisions of the Commissioner. Challenges to ADT-03 cost-recovery are rare in practice and usually focus on the underlying Section 66 nomination itself rather than the quantum. Where the Section 66 nomination was procedurally infirm (no Commissioner approval, no opportunity of being heard, no recorded reasons), the consequential ADT-03 cost-recovery similarly becomes vulnerable in writ proceedings. The OECD Forum on Tax Administration documents this cost-recovery pattern as common across jurisdictions that use specialist-audit tiers.

Payment timeline and Section 79 recovery framework

Once ADT-03 is served, the cost-recovery amount becomes payable within the timeline specified in the form (typically thirty days). Non-payment triggers Section 79 of the CGST Act — the Government dues recovery framework — which empowers the proper officer to recover the amount through modes including deduction from any amount due to the registered person, sale of any movable or immovable property, attachment of bank accounts under Section 83 provisional attachment, and recovery as land revenue arrears. The registered person can apply for instalment-payment under Section 80 read with Rule 158 where genuine financial hardship exists; the Commissioner has discretion to allow up to twenty-four monthly instalments subject to interest under Section 50.

Records retention under Section 35

Comparative framework — Income Tax Act 44AA and Companies Act records

The GST retention framework operates alongside the Income Tax Act Section 44AA requirement to maintain books of account for specified professions and businesses (with retention under Rule 6F for six years), and the Companies Act 2013 Section 128 requirement for books of account preservation for at least eight years preceding the current year. The longest applicable horizon governs — for a company carrying on a taxable supply business, the effective records-retention period is the Companies Act eight-year horizon. The OECD International VAT/GST Guidelines recommend a minimum retention of five years tied to the audit-period limitation, which the Indian GST framework comfortably exceeds. Coordinated retention policies across GST, income tax and Companies Act dimensions are the typical compliance design at well-run enterprises.

Statutory framework and retention horizon

Section 35(1) of the CGST Act requires every registered person to keep and maintain, at his principal place of business and at every additional place of business mentioned in the certificate of registration, a true and correct account of production or manufacture of goods, inward and outward supply of goods or services or both, stock of goods, input tax credit availed, output tax payable and paid, and such other particulars as may be prescribed. Section 36 mandates that every registered person required to keep books and accounts under Section 35 shall retain them until the expiry of seventy-two months from the due date of furnishing the annual return for the year pertaining to such accounts. The seventy-two-month (six-year) retention horizon aligns with the Section 73 normal-period limitation of three years from the due date of the annual return, and the Section 74 extended-period limitation of five years, with a safety margin.

Specific records prescribed under Rules 56 to 58

Rule 56 of the CGST Rules elaborates the records to be maintained under Section 35 — accounts of goods or services received and supplied, stock of goods (with opening balance, receipt, supply, goods lost stolen destroyed written off or disposed of by way of gift or free sample, balance), particulars of ITC availed, output tax payable and paid, names and complete addresses of suppliers and customers, complete addresses of premises where goods are stored including goods stored during transit, monthly production accounts (for manufacturers) showing quantitative details of raw materials and goods produced, and accounts of advances received and paid. Rule 57 provides for maintenance through electronic means with prescribed safeguards. Rule 58 covers transporter, owner and operator of warehouse records. The records-architecture is granular and audit teams systematically map registered-person records against the Rule 56 schema during Section 65 audits.

Glossary

Plain-English glossary for this service

Outward supply reconciliation

Outward supply reconciliation is the comparison of turnover declared in GSTR-1, turnover declared in GSTR-3B, turnover declared in GSTR-9 and turnover as per audited financial statements. The reconciliation is the focal table of GSTR-9C and is a recurring audit observation area.

Section 16(2)(aa)

Sub-clause (aa) of sub-section (2) of Section 16 of the CGST Act conditions input tax credit on the details of the invoice or debit note being furnished by the supplier in GSTR-1 and communicated to the recipient. Departmental audit observations under this provision typically address ITC availed in respect of invoices not reflected in GSTR-2B.

Section 17(5)

Sub-section (5) of Section 17 of the CGST Act lists blocked credits — motor vehicles below thirteen-seater capacity, food and beverages, club membership, works contract for immovable property and others. Audit observations on Section 17(5) frequently require itemised reconciliation of ITC against the negative list.

Reverse charge audit

Reverse charge audit is the subset of audit observations examining whether tax has been correctly paid by the recipient under sub-section (3) or (4) of Section 9 on notified supplies — goods transport agency, advocate services, sponsorship and others. The audit also tests whether ITC on RCM-paid tax has been availed only after payment of tax.

Composition audit

Composition audit is the audit of taxpayers paying tax under Section 10 of the CGST Act. The audit verifies turnover slabs, prohibited supplies (inter-State, e-commerce, ice-cream, pan masala, tobacco), maintenance of CMP filings and the rate of composition applied. CMP-08 quarterly statements and GSTR-4 annual return are the principal documents.

E-invoice audit

E-invoice audit examines compliance with the e-invoicing framework notified under sub-rule (4) of Rule 48 for taxpayers with aggregate turnover above the prescribed threshold. The audit traces invoice reference number (IRN), QR-code generation and reporting on the Invoice Registration Portal across the audited financial periods.

E-way bill audit

E-way bill audit is the examination of e-way bills generated under sub-rule (1) of Rule 138 for movement of goods of consignment value exceeding fifty thousand rupees. Audit observations typically address mismatches between e-way bill data, tax invoice data and GSTR-1 outward supply declarations.

Place of supply

Place of supply is determined under Chapter V of the IGST Act and dictates whether a supply is intra-State (CGST plus SGST) or inter-State (IGST). Audit observations on place of supply typically address services supplied to recipients in other States, goods movements without invoicing and exports without LUT.

Departmental audit

Departmental audit is the audit conducted by the GST department under Section 65 of the CGST Act covering a registered person for one or more financial years, commenced by ADT-01 and concluded by ADT-02, usually completed at the registered place of business or office of the proper officer.

Special audit

Special audit is the audit ordered under Section 66 by the Commissioner where the proper officer is of the opinion that the value or credit availed has not been correctly declared; it is conducted by a chartered accountant or cost accountant nominated by the Commissioner and triggered by Form ADT-03.

ADT-01 notice

ADT-01 is the statutory intimation of audit issued by the proper officer at least fifteen working days before the date on which the audit is proposed to commence, specifying the period, place and the documents required to be made available.

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.

By Industry

Industry-specific patterns in West Mambalam

How the local trade mix shapes this — In West Mambalam, the cluster of traditional retail, jewellery, residential businesses that defines West Mambalam's commercial fabric.

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.
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.
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.
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.
Case Studies

Anonymised engagements we have handled

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

Stock varianceFMCG distribution

Section 65 audit defended on stock variance for a {{area_name}} FMCG distributor

Issue: An FMCG distributor in {{area_name}} faced an ADT-01 audit alleging a stock variance of approximately twenty-four lakh rupees between Section 35 records and the physical-stock register at audit visit, with a proposed deemed-supply demand of approximately four lakh thirty thousand rupees.
Approach: We reconciled the stock variance against in-transit goods, sales-return ageing under Section 34 credit-note treatment, and damaged-stock write-offs supported by insurance claim records. Section 17(5)(h) blocked credit on goods lost, stolen or destroyed was acknowledged and reversed through DRC-03 for the relevant portion.
Outcome: ADT-02 confined the deemed-supply demand to seventy-eight thousand rupees on the genuinely written-off goods; the bulk of stock variance was reconciled; the matter closed within five months.
SEZ exemptionSEZ services

Notification 9/2017 IGST exemption defended at audit for a {{area_name}} SEZ unit

Issue: An SEZ unit operating from a {{area_name}} cluster received an ADT-01 audit alleging that zero-rated supplies of approximately seventy-two lakh rupees were claimed without proper Letter of Undertaking coverage, with a proposed IGST demand of approximately twelve lakh ninety thousand rupees.
Approach: We produced the LUT in Form GST RFD-11 covering the entire period, supplier-side endorsement by the specified officer of the SEZ, and the zero-rated supply reporting in Table 6A of GSTR-1. Section 16 of the IGST Act and Rule 96A of the CGST Rules were placed on record.
Outcome: ADT-02 accepted the zero-rated treatment; the entire twelve lakh ninety thousand rupee demand was dropped; subsequent year LUT was filed before the first day of April to preserve continuity.
HSN reportingChemicals manufacturing

Notification 78/2020 HSN reporting compliance defended at audit for a {{area_name}} chemicals manufacturer

Issue: A chemicals manufacturer in {{area_name}} faced an ADT-01 audit on alleged non-compliance with the HSN-code reporting requirement under Notification 78/2020-Central Tax, with a proposed penalty under Section 125 of approximately two lakh fifty thousand rupees across multiple invoices.
Approach: We demonstrated that aggregate turnover for the preceding financial year was above the five-crore threshold and that six-digit HSN was indeed reported on tax invoices and GSTR-1. Sample invoices, GSTR-1 HSN summary tables and the IRP-generated IRNs were filed.
Outcome: ADT-02 accepted the HSN-reporting compliance; the Section 125 penalty proposal was dropped; the matter closed without referral to DRC-01.
TRAN-1 transition creditEngineering services

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

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

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

Common Questions

GST Audit Support FAQ — West Mambalam

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

Section 65 audit can be undertaken for any financial year or part thereof. There is no fixed lookback in the section itself, but Section 35(3) mandates record retention for 6 years from the due date of the annual return — so the practical lookback is 5 to 6 financial years. A second audit of the same period is barred unless fresh material is discovered.
Yes. Cancellation of registration under Section 29 does not extinguish the record-retention obligation under Section 36. Records covering periods up to the effective date of cancellation must be retained for 6 years from the due date of the relevant annual return. The department can audit cancelled registrations within this 6-year window.
Yes — honest advice is the whole point. If GST Audit Support is not right for your West Mambalam situation, or can safely wait, we will say so plainly rather than sell you something. That is why much of our work comes through referrals.
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.
Section 66(2) requires the nominated auditor to submit the special audit report within 90 days of the ADT-03 order. The Assistant Commissioner may, on application by the auditor or the registered person and on reasonable grounds, extend the period by a further 90 days — taking the maximum to 180 days from the ADT-03 order date.
Call or WhatsApp 9566-068-468 with a one-line description of your requirement. We confirm exactly which documents your West Mambalam case needs, share a fixed quote upfront, and start once you approve. The first discussion is free.
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.
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.
Yes — 600033 (West Mambalam) is well within our service area. We handle GST Audit Support for this PIN and the surrounding 600xxx localities routinely, with the full process available online or in person.
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.
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.
Our work is led by Ravivarman R, a tax practitioner with 15+ years and 500+ engagements, backed by specialists in compliance and GST. We base every GST Audit Support recommendation on current law and your actual facts — not generic templates — and we are happy to explain the reasoning.
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-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.
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 36(1) read with Rule 56(15) recognises electronic records — accounting software ledgers, e-invoice IRN logs, e-way bill register and digital purchase registers. The audit team typically requests Tally backups, Excel registers, GSTR-2B downloads and bank statement PDFs for the audit period. Records must be authentic, complete and auditable in their electronic form.
