Why FilingPro?

Why Tiruvottiyur Clients Choose FilingPro

Expert GST Audit Support in Tiruvottiyur — 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.

People Also Ask — GST Audit Support in Tiruvottiyur
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 the difference between Section 65 audit and Section 66 special audit?

Section 65 is a departmental audit conducted by the proper officer at the registered person's place. Section 66 is a special audit ordered by an Assistant Commissioner directing a Commissioner-nominated Chartered Accountant or Cost Accountant to conduct the examination on specified grounds.

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

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

What is 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.

Reading this guide locally — In Tiruvottiyur, on the Manali-Tondiarpet corridor that passes through Tiruvottiyur; Tiruvottiyur businesses in the heavy manufacturing arm find that GST inverted-duty refunds capital-goods ITC and Rule 42/43 apportionment dominate the compliance workload.

What is a GST audit and where does it sit in the compliance architecture

Statutory framework under Chapter XIII of the CGST Act

The audit framework under the Central Goods and Services Tax Act 2017 is contained in Chapter XIII, comprising Sections 65, 66 and 71. Section 65 provides for departmental audit, Section 66 for special audit by a Chartered Accountant or Cost Accountant nominated by the Commissioner, and Section 71 for access to business premises by an authorised officer. The Empowered Committee 2009 First Discussion Paper had envisaged audit as the principal verification layer in a self-assessment regime, replacing the pre-GST pattern of routine assessment under the VAT/CST framework. The architecture is risk-based: not every registered person is audited; selection is driven by Section 65(2) read with internal CBIC risk-management directions which factor in turnover scale, sectoral risk profile, prior compliance history and reconciliation gaps surfaced in GSTR-9C self-certification. The audit-process closure under Section 65(7) feeds either into a no-objection certificate, a voluntary DRC-03 payment, or an SCN under Section 73 or Section 74 depending on whether tax has been short-paid, short-collected or wrongly availed as ITC.

Audit versus assessment versus inspection

Audit under Section 65 or 66 is conceptually distinct from assessment under Sections 61 (scrutiny of returns) and 62 (best-judgement assessment of non-filers) and from inspection / search / seizure under Section 67. Scrutiny under Section 61 is a desk-review of returns by the proper officer who issues ASMT-10 on discrepancies; the registered person responds in ASMT-11; closure or escalation follows. Audit is broader — Section 65(5) permits examination of the books, returns, statements, declarations and other documents to verify correctness of turnover declared, taxes paid, refund claimed and ITC availed, plus assessment of compliance with the Act. Inspection under Section 67 is targeted enforcement upon reason-to-believe of tax evasion and is invasive — premises access, seizure of records and goods. The OECD Forum on Tax Administration's compliance-pyramid model recommends graduated escalation from desk review to field audit to inspection, and the Indian framework broadly mirrors that design.

Self-certification under GSTR-9C and its audit interplay

Until Finance Act 2021 amendments, Section 35(5) had required certification of GSTR-9C by a Chartered Accountant or Cost Accountant for registered persons whose aggregate turnover exceeded the prescribed threshold. The Finance Act 2021 substituted Section 35(5) and amended Section 44, shifting GSTR-9C to a self-certified reconciliation statement filed by the registered person without third-party attestation, effective FY 2020-21 onwards (Notification 29/2021-CT). The reconciliation in GSTR-9C between audited financial statements and GSTR-9 annual return is now an internal-control disclosure; it does not substitute for departmental audit under Section 65. Audit teams treat GSTR-9C self-certified reconciliations as primary working papers — Table 5 (turnover reconciliation), Table 9 (tax payable reconciliation) and Table 12-14 (ITC reconciliation) become the starting points of Section 65 audit interrogation.

Section 66 special audit by CA / CMA

Comparative framework — special audit in income tax and GST

The income-tax framework has a parallel under Section 142(2A) of the Income Tax Act 1961 — special audit can be directed where the Assessing Officer, having regard to the nature and complexity of the accounts, the volume of accounts, doubts about the correctness of the accounts, multiplicity of transactions in the accounts or specialised nature of business activity, is of the opinion that it is necessary in the interests of revenue. Pre-GST excise had Section 14A; service tax had Section 72A. The architectural unity across these provisions is that special audit is a complexity-triggered intervention requiring a substantive opinion plus a procedural safeguard. The OECD Forum on Tax Administration documents a similar 'specialist audit' tier in several mature tax jurisdictions, reserved for complex high-revenue cases.

Trigger conditions under Section 66(1)

Section 66(1) of the CGST Act provides that if at any stage of scrutiny, inquiry, investigation or any other proceedings, any officer not below the rank of Assistant Commissioner, having regard to the nature and complexity of the case and the interest of revenue, is of the opinion that the value has not been correctly declared or the credit availed is not within the normal limits, he may, with the prior approval of the Commissioner, direct such registered person by communication in writing to get his records including books of account examined and audited by a Chartered Accountant or a Cost Accountant as may be nominated by the Commissioner. The trigger requires both a substantive opinion (value mis-declaration or abnormal credit) and a procedural pre-condition (Commissioner's prior approval); the registered person can challenge either limb in a Section 75 representation.

Procedural sequence under Section 66(2) to 66(5)

Once the Section 66(1) opinion is formed and Commissioner's approval obtained, Section 66(2) requires the nominated Chartered Accountant or Cost Accountant to submit a report duly signed and certified, in such form as prescribed (Form ADT-04), within ninety days; this period can be extended by a further ninety days on application by the registered person or the CA/CMA, with the Commissioner's permission. Section 66(3) requires that the registered person be given an opportunity of being heard in respect of any material gathered on the basis of the special audit and proposed to be used in any proceeding against him. Section 66(4) clarifies that the expenses of the examination and audit, including remuneration of the CA/CMA, shall be determined and paid by the Commissioner. Section 66(5) preserves the proper officer's power to take further proceedings (SCN under Section 73 / 74) on the basis of the special audit findings.

ADT-01 intimation

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.

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).

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.

Glossary

Plain-English glossary for this service

Terms you will hear in this area — In Tiruvottiyur, where SIDCO-CMDA developed engineering units operate on B2B procurement and capital-goods ITC accumulation cycles.

DRC-01A

DRC-01A is the pre-show-cause-notice intimation prescribed under sub-rule (1A) of Rule 142. Part A is the officer's quantification of tax ascertained as payable on the basis of audit observations; Part B is the registered person's reply or acceptance. DRC-01A is the principal off-ramp before formal proceedings under Section 73 or 74.

DRC-03

DRC-03 is the voluntary-payment intimation prescribed under sub-rule (2) and (3) of Rule 142. It is filed where the registered person makes voluntary payment of tax, interest or penalty including pre-SCN deposit under Section 73(5) or 74(5). DRC-03 is the principal vehicle for closing out audit observations without formal adjudication.

Section 73(5) deposit

Section 73(5) deposit is the voluntary payment made by the registered person, on his own ascertainment or on ascertainment by the proper officer, before issuance of a show-cause notice. The deposit, when made along with applicable interest under Section 50, results in no penalty being leviable under Section 73(9).

Audit jurisdiction

Audit jurisdiction refers to the statutory authority of the Commissioner under sub-section (1) of Section 65 to authorise any officer to undertake audit of a registered person. Authorisation may be by general or specific order. A challenge to audit jurisdiction is typically agitated at the threshold under Article 226 before the High Court.

Section 67 search

Section 67 search is the enforcement-track action distinct from departmental audit. The proper officer not below the rank of Joint Commissioner, with reasons to believe that tax has been suppressed or credit wrongly availed with intent to evade tax, may authorise in writing any officer to inspect places of business and seize goods or documents.

Best-judgment assessment

Best-judgment assessment is the framework under Section 62 or Section 63 by which the proper officer, where a registered person fails to furnish returns or where an unregistered person is liable, assesses the tax liability to the best of his judgment. Audit non-cooperation can be a trigger for invoking Section 62.

Aggregate of demands

Aggregate of demands captures the total tax, interest and penalty proposed in DRC-01 or confirmed in DRC-07 arising from audit observations. The aggregate determines the appellate forum, the pre-deposit obligation under Section 107(6) and the merits of pursuing rectification under Section 161.

Pre-deposit

Pre-deposit under sub-section (6) of Section 107 is the mandatory deposit of ten percent of the remaining amount of tax in dispute, subject to a maximum of twenty crore rupees, required for the appeal to be maintainable before the Appellate Authority. The pre-deposit is in addition to admitted tax, interest, fine and penalty.

First appeal

First appeal under sub-section (1) of Section 107 lies before the Appellate Authority against any decision or order passed under the CGST Act by an adjudicating authority. The appeal must be filed within three months from the date of communication of the order, condonable by a further one month on sufficient cause.

Rectification

Rectification under Section 161 of the CGST Act is the remedy for any error apparent on the face of record in any decision, order, notice, certificate or any other document. Rectification may be undertaken suo motu by the authority or on application by the registered person within three months of the document.

ITC reversal

ITC reversal is the substantive consequence of an audit observation that input tax credit has been wrongly availed or utilised. Reversal is effected through Table 4(B) of GSTR-3B with interest under Section 50(3) and, in some cases, penalty under Section 73(9) or 74(9) depending on the nature of the lapse.

Interest under Section 50

Interest under Section 50 is the statutory consequence of delayed payment of tax or wrong availment and utilisation of input tax credit. Sub-section (1) prescribes interest at the rate of eighteen percent per annum on delayed payment, and sub-section (3) prescribes interest at the rate of twenty-four percent for wrongful utilisation of ITC.

Cost of Non-Compliance

Real-world penalty exposure

Numerical examples showing tax + interest + penalty across common default scenarios.

Penalty exposure typical of this micro-market — In Tiruvottiyur, Tiruvottiyur businesses in the heavy manufacturing arm find that GST inverted-duty refunds capital-goods ITC and Rule 42/43 apportionment dominate the compliance workload; supporting the engineering and operator workforce that lives in the surrounding residential belts.

By Industry

Industry-specific patterns in Tiruvottiyur

How the local trade mix shapes this — In Tiruvottiyur, where SIDCO-CMDA developed engineering units operate on B2B procurement and capital-goods ITC accumulation cycles; the business activity radiating outward from Tiruvottiyur Beach and nearby commercial pockets.

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.
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.
Manufacturing
Common issue: Small manufacturers in industrial estates undergoing audit struggle with Rule 56 stock-records adequacy. Rule 56(2) requires a true and correct account of production, raw materials, finished goods and waste, but many SMEs maintain only tally inventory without the legally required day-wise production register, opening the door to estimated-suppression additions under Section 73.
How we handle it: Reconstruct Rule 56(2) registers using Tally batch data, weighbridge slips and electricity-consumption normative ratios well before the ADT-01 intimation period closes. Bundle the reconstruction with a contemporaneous reconciliation note explaining the SOP gap; voluntary DRC-03 payment of any genuine differential closes the issue at audit stage rather than at SCN.
Manufacturing
Common issue: Manufacturers undertaking SEZ supplies under LUT face Section 65 audit scrutiny on Rule 96A timeline compliance for export realisation. Where SEZ payment realisation crosses fifteen months, the IGST recovery proposal under Rule 96A(1) provisos can be sizable, and the audit team often invokes interest under Section 50(1) from the original supply date.
How we handle it: Maintain a SEZ-LoA wise realisation tracker tied to RBI FIRC and SOFTEX certificates. For consignments exceeding fifteen months, file a representation citing the relaxations notified under various Notifications during FY 2020-21 (78/2020-CT etc.) and the GST Council 47th Chandigarh recommendations on realisation timelines.

Composite supplySolar EPC

Composite supply treatment defended at audit for a {{area_name}} solar EPC contractor

Issue: A solar EPC contractor in {{area_name}} received ADT-01 alleging that bundled supply of solar panels with installation services should have been split as goods at eighteen per cent and services at eighteen per cent, with a proposed differential demand of approximately seventeen lakh rupees on the seventy-thirty deemed-split route.
Approach: We anchored the reply on Section 2(30) read with Section 8(a) for composite supply and demonstrated that the principal supply was the solar power generating system, attracting the concessional rate as it then stood. Notification 24/2018-Central Tax (Rate) and the AAAR ruling in Solairedirect were placed on record.
Outcome: ADT-02 accepted the composite-supply treatment; the seventeen lakh rupee differential was dropped; the rate position was carried into subsequent contracts with documentary backup.
Section 143 job-workEngineering job-work

Job-work return discipline under Section 143 defended at audit for a {{area_name}} engineering job-worker principal

Issue: An engineering principal in {{area_name}} received an ADT-01 audit on alleged non-return of inputs sent for job-work within the one-year period under Section 143(1)(a), with a proposed deemed-supply tax of approximately nine lakh rupees on inputs of approximately seventy lakh rupees in value.
Approach: We produced ITC-04 quarterly returns, job-work challans under Rule 45, e-way bills evidencing return of processed goods within the one-year window, and reconciled stock at the job-worker against the principal's books. Where return was delayed, the deemed supply was acknowledged and paid through DRC-03 with interest.
Outcome: ADT-02 confined the deemed-supply demand to eighty-seven thousand rupees on three challans; the bulk of nine lakh rupees was dropped; the matter closed without DRC-01 escalation.
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.
GTA forward-chargeGoods transport

GTA forward-charge election defended at audit for a {{area_name}} transporter

Issue: A goods-transport agency in {{area_name}} received an ADT-01 audit on a contention that its forward-charge election under Notification 11/2017-Central Tax (Rate) as amended by Notification 3/2022 was invalid for the relevant year, with a proposed demand of approximately fifteen lakh rupees on a deemed RCM-only basis.
Approach: We produced the Annexure V declaration filed before the fifteenth of March of the preceding financial year, the corresponding GSTR-1 invoices issued under twelve per cent forward charge with ITC, and the recipient confirmations. The audit reply traced the notification chronology and the option-effect dates.
Outcome: ADT-02 accepted the forward-charge election; the fifteen lakh rupee deemed-RCM demand was dropped; subsequent year Annexure V was filed within window to preserve the election.

GST Audit Support FAQ — Tiruvottiyur

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

Recurring findings include — ITC mismatch between GSTR-2B and GSTR-3B, Section 17(5) blocked credits wrongly availed (motor vehicles for personal use, food and beverages, club memberships), RCM not paid on advocate fees and GTA, e-way bill missing for consignments above ₹50,000, e-invoice non-compliance for taxpayers above ₹5 crore AATO, HSN summary errors in GSTR-1 Table 12, and Schedule III adjustments not made for related-party transactions.
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.
We review GST Audit Support work carefully before submission to avoid errors in the first place. If a genuine issue ever arises on something we filed for a Tiruvottiyur client, we help set it right — standing behind our work is part of the service.
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.
The Madras High Court in Tvl. Diya Agencies v. State Tax Officer (W.P. 16866/2023) and similar rulings have held that the recipient who has paid consideration with tax to the supplier and filed valid returns cannot be denied ITC merely because the supplier did not pay tax to the exchequer — provided Section 16 conditions are otherwise met. Audit teams cannot mechanically reverse ITC on this ground alone.
It is simple: you share your requirement and documents over WhatsApp or email, we prepare and review the work, send it to you for approval, then complete the filing. Tiruvottiyur clients get the same quality remotely as in person, with an update at every step.
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.
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.
Turnaround depends on the service and how quickly you share documents. Once we have a complete set, GST Audit Support for Tiruvottiyur 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 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.
Yes. The Madras High Court in Tvl. Raja Stores v. Assistant Commissioner (W.P. 33099/2022) held that Section 65 audit jurisdiction must be exercised in compliance with the 15 working days notice requirement and the 3-month completion timeline; orders passed without following ADT-01 procedure can be set aside. Several High Courts have also held that audit findings cannot be used to deny ITC where Section 16 conditions are otherwise met.

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).
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.
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.
Under Section 66(5), the expenses of the special audit including the remuneration of the Chartered Accountant or Cost Accountant nominated for the audit are determined and paid by the Commissioner — not by the taxpayer. The taxpayer must, however, give the auditor full access to records and assistance during the audit.
