People Also Ask — GST Audit Support in Koyambedu
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.
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 Form ADT-01 in GST?

Form ADT-01 is the audit-commencement notice issued by the proper officer under Rule 101(2) read with Section 65(3) of the CGST Act 2017. It precedes the audit and triggers the fifteen-working-day record-preparation window for the registered person.

What does Form ADT-02 set out at the close of a departmental audit?

Issued under Rule 101(5), Form ADT-02 documents the proper officer's conclusions on alleged short paid tax, ineligible credit and consequential interest. The instrument is a finding only; any monetary demand thereafter is crystallised through DRC-01 under Section 73 or 74.

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.

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-01 intimation

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.

Seeking extension of the audit-commencement date

Where genuine grounds exist — pending statutory audit of financial statements, key personnel unavailability, or recent migration of accounting systems — the registered person can seek extension of the audit commencement date by written representation. The audit team has administrative discretion under Rule 101 to grant reasonable extensions, generally up to thirty additional days; longer extensions require Commissioner-level approval. The extension must be sought before the proposed commencement date and supported by documentary evidence (statutory auditor engagement letter, employee leave records, ERP migration plans). The OECD Forum on Tax Administration best-practice benchmarks recognise such extensions as a taxpayer-rights safeguard, balanced against the audit-closure timeline.

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.

ADT-02 audit report

Form, statutory basis and contents

Form GST ADT-02 is the audit-closure report prescribed under Rule 101(5) of the CGST Rules and Section 65(7) of the CGST Act. Upon completion of the audit, the proper officer is required to issue ADT-02 within thirty days informing the registered person of the findings, the rights and obligations, and the reasons for such findings. ADT-02 captures the period audited, the audit observations under each verification head (turnover, ITC, refund, classification, rate, valuation), the proper officer's conclusion on each observation, the tax / interest / penalty quantum where applicable, and the rights of the registered person to dispute or accept the findings. The form is the formal closure of the audit cycle and the trigger for the next-stage decision — voluntary DRC-03 payment, SCN under Section 73 or 74, or no-action closure.

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.

ADT-03 cost recovery

Cost-recovery in practice — pattern from Tamil Nadu Commissionerates

In practice, ADT-03 cost-recovery determinations issued by Tamil Nadu Commissionerates have ranged from modest amounts (₹50,000-₹2 lakh for limited-scope special audits) to substantial amounts (₹10 lakh and above for multi-year complex audits involving multiple GSTINs). The pattern correlates with the audit-scope — broad valuation or ITC-eligibility audits at large multi-State entities typically yield higher cost-recovery quantums. Registered persons under Section 66 nomination are well-advised to engage with the CA/CMA on a documented scope-limitation memorandum to control the quantum; reasonableness of the determination is reviewable in writ jurisdiction though the threshold for interference is high.

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.

What Koyambedu clients usually ask next: On the ground in Koyambedu, where wholesale traders cold-storage operators and inter-state logistics firms generate high-volume e-way bill GST and inter-state IGST compliance loads; for Koyambedu wholesalers managing dense daily inventory turnover and inter-state compliance footprints.

Glossary

Plain-English glossary for this service

Terms you will hear in this area — Across Koyambedu, where wholesale traders cold-storage operators and inter-state logistics firms generate high-volume e-way bill GST and inter-state IGST compliance loads.

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.

ADT-03 direction

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

Audit period

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

Pre-ADT-02 window

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

Rule 56 records

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

Six-year retention

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

Records walkthrough

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

Adverse finding

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

By Industry

Industry-specific patterns in Koyambedu

How the local trade mix shapes this — Across Koyambedu, where wholesale traders cold-storage operators and inter-state logistics firms generate high-volume e-way bill GST and inter-state IGST compliance loads. Practitioners note that the cluster of restaurant chains hotels and CMDA-developed commercial blocks along Periyar EVR Salai and 100ft Road.

Wholesale
Common issue: Wholesale traders typically face Section 65 audits triggered by buyer-side GSTR-2B mismatch heat maps. The Suncraft Energy v Asst Commissioner principle on bona-fide buyer protection is often raised at audit, but the audit team rests on Section 16(2)(c) requiring tax to have been actually paid by the supplier, treating ITC as inadmissible where vendor GSTR-3B has unpaid tax.
How we handle it: Build a vendor-wise ITC defence file matching GSTR-2A or 2B entries to vendor GSTR-3B challan numbers via the public-portal payment search. Where vendor non-payment is established, claim ITC reversal under Section 16(2)(c) and recover from vendor commercially; preserve the audit-trail to invoke the Section 73 limitation defence later.
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.
Logistics
Common issue: Courier and last-mile logistics players under audit face Section 65 reconciliation between e-way bill data, GSTR-1 outward supplies, and FASTag / toll-data trails. Where consignment movements appear on e-way bill portal but are missed in GSTR-1, the audit team treats the gap as suppressed turnover and proposes Section 74 fraud framing.
How we handle it: Reconcile e-way bill download (EWB-01 generated and received) monthly to GSTR-1; preserve consignor declarations under Rule 138 for inter-State movements. Where genuine gaps exist (e.g. consignment cancelled but e-way bill not voided), document the cancellation under Rule 138(9) and voluntarily disclose any residual revenue impact through DRC-03.
Pharmaceuticals
Common issue: Pharma manufacturers face Section 65 audits on Rule 89(5) inverted-duty refund eligibility — API inputs at 18% versus formulation outputs at 12% or 5% generate accumulated ITC. The audit team often re-computes refund post VKC Footsteps (excluding input services) and surfaces excess-refund recovery proposals running into multiple financial years.
How we handle it: Recompute Rule 89(5) refund for all open years excluding input-services ITC; quantify the excess-refund exposure and voluntarily disclose under Section 73(5) via DRC-03. Preserve API-to-formulation batch-traceability working papers; cite the Notification 14/2022-CT amendment to Rule 89(5) which prospectively restricted the formula scope.
Plastics
Common issue: Plastic manufacturers under audit face HSN classification disputes between Chapter 39 primary forms (typically 18%) and Chapter 39 secondary moulded products (varying rates). Wrong HSN at REG-01 cascades into wrong-rate audit findings; the audit team frequently invokes Section 74 (fraud) framing rather than Section 73 where classification was clearly deliberate.
How we handle it: Obtain a contemporaneous classification opinion from a tax practitioner or seek an Advance Ruling under Section 97 for borderline HSN cases. Where classification was bona-fide but incorrect, voluntarily pay differential under DRC-03 to mitigate the Section 74 fraud framing; this typically converts the case to Section 73 with reduced penalty exposure.

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.
Rule 56 records gapTrading

Rule 56(1) ledger gap of seven months — reconstructed from bank and e-invoice in eight days

Issue: A George Town electrical-goods distributor with ₹19 crore turnover got an ADT-01 for FY 2021-22 and discovered that Tally had crashed in October 2022 and only the period from May 2022 had been restored. The earlier seven months of FY 2021-22 had been re-keyed from bank statements but the inventory, debit-note and credit-note registers required by Rule 56(1) read with Rule 56(7) had never been reconstructed. Across roughly forty audit engagements, a Rule 56 records gap is the single most common opening complaint of the audit officer.
Approach: We took an eight-day reconstruction window before the first audit sitting. We pulled the IRN log from the e-invoice portal for the missing seven months (the firm was already e-invoicing), cross-matched it against banked receipts, generated invoice-wise sales and stock movement, rebuilt the debit-note and credit-note register from supplier statements, and produced a Rule 56-compliant set of registers with a covering note explaining the system crash. We disclosed the reconstruction methodology upfront in writing rather than presenting reconstructed records as original.
Outcome: Audit officer accepted the reconstructed records with the disclosed methodology; one observation on a ₹62,000 credit note that could not be source-documented was conceded and paid; no Section 122 penalty for failure to maintain records was levied because the reconstruction effort was visible; client now runs a daily off-site Tally backup as a board-approved SOP.
ADT-02 negotiationLogistics

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

Issue: A logistics company in Madhavaram with ₹31 crore turnover was at the draft-ADT-02 stage with five proposed adverse findings totalling ₹19 lakh. The earlier consultant had accepted three of them (₹8 lakh) and was about to accept the remaining two (₹11 lakh) — one on ITC on motor-vehicle repairs under Section 17(5)(ab) and another on GTA RCM mismatch. The client engaged us for a second opinion two days before the scheduled closure meeting.
Approach: We re-examined both findings overnight. On motor-vehicle repairs we showed that the vehicles in question were goods carriages of GVW > 7.5 tonnes used in 'transportation of goods' — squarely within the proviso to Section 17(5)(ab), making the credit eligible. On the GTA RCM mismatch we reconciled GSTR-3B Table 3.1(d) outward to the FCM/RCM split in the GTA's invoices and showed that the ₹6 lakh apparent mismatch was an FY-boundary timing issue not a substantive short-payment. We requested a partner-led closure meeting with documentary backup.
Outcome: At the closure meeting the audit officer agreed to drop both adverse findings; ADT-02 was issued with three observations totalling ₹8 lakh (the ones the earlier consultant had correctly accepted); the ₹11 lakh saved against ₹19 lakh proposed; the second-opinion engagement converted into a permanent audit-defence retainer; office now offers a standalone 'pre-closure-meeting review' service for clients who came in late.
Notification 14/2022Logistics

Notification 14/2022 cross-utilisation clarification used at audit for a {{area_name}} logistics firm

Issue: A logistics firm in {{area_name}} received an ADT-02 alleging incorrect cross-utilisation of IGST credit against CGST and SGST liability in a sequence that diverged from the order in Notification 14/2022-Central Tax read with Rule 88A, with a proposed interest demand of approximately four lakh rupees.
Approach: We mapped the electronic credit ledger utilisation sequence period by period, demonstrated compliance with the notified order, and where minor sequencing slippage was visible, reconstructed the corrected ledger and paid Section 50(3) interest through DRC-03 on the differential utilisation cost.
Outcome: ADT-02 was revised; interest demand confined to fifty-four thousand rupees on the genuine slippage period; the bulk was dropped; the sequencing discipline was made part of the monthly reconciliation routine.

Why these Koyambedu engagements look the way they do: On the ground in Koyambedu, the cluster of restaurant chains hotels and CMDA-developed commercial blocks along Periyar EVR Salai and 100ft Road; for Koyambedu wholesalers managing dense daily inventory turnover and inter-state compliance footprints.

Common Questions

GST Audit Support FAQ — Koyambedu

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

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 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.
Absolutely. Most Koyambedu clients complete the entire GST Audit Support process remotely — we collect documents on WhatsApp or email, share drafts for your approval, and file on your behalf. A visit to our Maduravoyal office is optional, never required.
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.
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.
Yes — we work comfortably in both Tamil and English, which makes explaining GST Audit Support to Koyambedu clients straightforward. Ask your questions in whichever language you prefer, by call or WhatsApp on 9566-068-468.
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.
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.
Delays in statutory work can mean penalties, interest or blocked services that usually cost far more than acting on time. For Koyambedu 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).
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.
Yes — 600107 (Koyambedu) 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 65 audit is conducted at the principal place of business as registered in REG-06. If the audit covers transactions of branches (additional places of business), the records of those branches must be produced at the principal place or made accessible to the audit team. Koyambedu businesses with branches outside Tamil Nadu must coordinate branch records to the audit venue.
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.
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.
Yes. ADT-02 must record findings with reasons; Section 66(6) expressly mandates a hearing opportunity before special audit material is used in proceedings; and any DRC-01 SCN must give 30 days for DRC-06 reply with personal hearing. Courts have consistently set aside audit-driven demands where the taxpayer was not given proper opportunity to be heard.
