People Also Ask — GST Audit Support in Siruseri IT SEZ
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.
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 is the due date for GSTR-9 and GSTR-9C filing?

GSTR-9 along with GSTR-9C where applicable is due by the thirty-first of December following the relevant financial year. Section 44 read with Rule 80 governs the due date, subject to periodic extensions notified by the Central Board of Indirect Taxes and Customs.

Which document sets does the audit team typically demand at ADT-01 stage?

Section 35 with Rule 56 obliges the registered person to keep the universe of tax invoices, stock and production registers, ITC workings, output liability schedules, RCM register, e-way bill logs, IRN files, Section 17(5) computations and matched bank statements ready for production.

What is the statutory record-retention horizon under GST?

Section 36 fixes the horizon at six years measured from the GSTR-9 due date for that year. Where any appeal, revision or proceeding remains pending, retention runs until one year after final disposal or six years, whichever event is later in time.

Can a second GST audit be conducted for the same period?

A second Section 65 audit of the same period is generally not undertaken absent fresh material. However, special audit under Section 66 may be ordered even where Section 65 audit was earlier conducted, and other proceedings under the Act remain available where conditions are met.

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

Section 67

Section 67 of the CGST Act is the inspection, search and seizure provision. The proper officer not below the rank of Joint Commissioner, where he has reasons to believe that tax has been suppressed or credit has been wrongly availed with intent to evade tax, may authorise inspection of places of business. Section 67 is a distinct enforcement track and is not the same as the audit jurisdiction under Section 65.

Section 73

Section 73 of the CGST Act governs the determination of tax not paid, short paid, erroneously refunded or input tax credit wrongly availed for reasons other than fraud, wilful misstatement or suppression of facts. Order under sub-section (10) may be passed within three years from the due date of annual return; SCN at least three months prior.

Section 74

Section 74 of the CGST Act governs the determination of tax not paid, short paid, erroneously refunded or input tax credit wrongly availed by reason of fraud, wilful misstatement or suppression of facts to evade tax. The limitation extends to five years from the due date of the annual return. Penalty equal to the tax demanded is leviable.

Rule 101

Rule 101 of the CGST Rules prescribes the procedure for audit under Section 65. Sub-rule (1) provides that the audit period shall be a financial year or part thereof or multiples thereof. Sub-rule (2) prescribes Form ADT-01 for the audit notice. Sub-rule (4) deals with discrepancy notes and sub-rule (5) prescribes Form ADT-02 for communication of findings.

Rule 102

Rule 102 of the CGST Rules prescribes the procedure for special audit under Section 66. Sub-rule (1) prescribes Form ADT-03 for the direction to the registered person, and sub-rule (2) prescribes Form ADT-04 for communication of the findings of the special audit to the registered person.

Place of audit

Place of audit is governed by sub-section (2) of Section 65 which permits the audit to be conducted either at the place of business of the registered person or at the office of the proper officer. The choice rests with the department; the registered person does not have a unilateral right to require off-site audit.

Date of commencement of audit

Date of commencement of audit is defined in the Explanation to sub-section (4) of Section 65. It is the date on which the records and other documents called for by the tax authorities are made available by the registered person, or the actual institution of audit at the place of business, whichever is later. The ninety-day completion clock runs from this date.

Conclusion of audit

Conclusion of audit is the point at which the field-verification and records-examination work under Section 65 is finished. The thirty-day clock for issuance of ADT-02 under sub-section (6) of Section 65 starts running from conclusion. Conclusion is distinct from the date of communication of findings.

Period of audit

Period of audit under sub-rule (1) of Rule 101 shall be a financial year or part thereof or multiples thereof. A multi-year audit is permissible where the audit notice in ADT-01 specifies the periods covered. The earliest period audited typically corresponds to records retention horizon under Section 36.

Audit notes

Audit notes are the contemporaneous record maintained by the proper officer during the conduct of audit under Rule 101. Discrepancies recorded in the audit notes are communicated to the registered person under sub-rule (4) of Rule 101 with an opportunity to reply before the findings are crystallised in ADT-02.

Discrepancy memo

Discrepancy memo is the informal communication, contemplated under sub-rule (4) of Rule 101, by which the proper officer informs the registered person of observations recorded during audit. The registered person files a written reply with supporting reconciliations before ADT-02 is issued.

Books of account

Books of account refer to the records required to be maintained under sub-section (1) of Section 35 of the CGST Act — accounts of production or manufacture, inward and outward supply, stock, ITC availed, output tax payable and paid. Maintenance at the principal place of business is the default; additional places require records of the additional location.

By Industry

Industry-specific patterns in Siruseri IT SEZ

How the local trade mix shapes this — In Siruseri IT SEZ, the cluster of it services, ites, software businesses that defines Siruseri IT SEZ's commercial fabric.

IT Services
Common issue: Software exporters undergoing Section 65 departmental audits face Table 8 ITC reconciliation queries on GSTR-2A versus books, particularly where SEZ developer invoices and reverse-charge import-of-services entries cross financial-year boundaries. The OECD International VAT/GST Guidelines treat exports as zero-rated under the destination principle, but the proper officer expects FIRC-realised consideration to tie back to invoice-month GSTR-1 disclosure within an audit-defensible bridge.
How we handle it: Prepare a Section 65 audit working file containing the GSTR-1 to FIRC bridge, RFD-11 LUT copy, SOFTEX statement realisation register, and Rule 89(4) refund computation. Map every GSTR-2A entry to vendor PAN and invoice number; preserve reverse-charge self-invoices under Section 31(3)(f) for the seven-year horizon in Section 36 read with Rule 56.
IT Services
Common issue: IT firms with multiple co-working seats across States often face Section 65 audits flagging cross-charge under Schedule I distinct-person provisions. Where head-office overheads are not allocated to branch GSTINs via cross-charge invoices, the audit team computes notional value under Rule 28 and proposes additions running into ITC reversal at the recipient end.
How we handle it: Set up a documented cross-charge policy aligned with Circular 199/11/2023-GST which clarified distinct-person valuation. Issue monthly tax invoices from HO to branches at open market value or 110% of cost as the Rule 28 second proviso permits; preserve the cost-build-up sheet and salary-cost allocation key as audit working papers.
Government
Common issue: Government-establishment vendors face Section 65 audits with REG-07 deductor mismatches as the primary trigger. Where the deductor captured a wrong GSTIN or omitted Section 51 TDS deduction, the vendor's cash ledger does not show the expected credit; audit teams treat the gap as suppressed output liability rather than as a deductor-side default.
How we handle it: Maintain a contract-wise REG-07 / GSTR-7 reconciliation register; pursue deductors for corrections through Section 51(3) certificate amendments. Cite Notification 50/2018-CT for the threshold and procedural framework; where deductor non-compliance is established, file a Section 75 representation explaining the gap as a third-party-non-compliance rather than vendor concealment.
Pharmaceuticals
Common issue: Pharma distributors operating across States face Section 65 audits with multi-State inter-State stock transfer reconciliation as the focal issue. Each State GSTIN is a distinct person under Schedule I; stock transfers without proper invoicing and e-way bills attract detention under Section 129 plus Section 73 demand at the audit stage for cumulative omitted IGST.
How we handle it: Reconcile branch-stock-transfer registers to outward GSTR-1 (Schedule I supplies) and inward GSTR-2A (recipient branch); ensure each transfer is supported by a tax invoice and an e-way bill where value crosses ₹50,000. Where transfers were missed historically, voluntarily disclose via DRC-03 with the offsetting ITC claim at the recipient branch.
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.

Anonymised engagements we have handled

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

Table 8 reconciliation cureIT Services

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

Issue: A Tidel Park IT-services company with ₹56 crore turnover was audited under Section 65 for FY 2021-22. The audit officer flagged a Table 8D negative of ₹47 lakh in the filed GSTR-9 and proposed in a draft observation note to demand reversal under Section 74 read with Rule 86A. The earlier consultant had filed Table 8 using auto-populated 8A without rebuilding from the underlying 2B and the difference looked like ineligible credit.
Approach: We requested a fifteen-day window to file a written reply before ADT-02 was issued — this pre-ADT-02 window under Section 65(6) read with the audit manual is where the cure has to happen, because once ADT-02 lands the matter moves to Section 73/74 proceedings. We rebuilt 8A from 2B for all twelve months, isolated ₹31 lakh of supplier invoices that the 2B export-limit truncation had dropped, identified ₹14 lakh of legitimate next-FY availment that belonged in 8C, and parked the residual ₹2 lakh in 8E with a working note.
Outcome: ADT-02 was issued without the Table 8 observation; only the ₹2 lakh residual was demanded under Section 73 (normal period, no penalty); the cure saved the client roughly ₹19 lakh in proposed interest and ₹47 lakh in proposed reversal; office rule was tightened — every GSTR-9 client now gets a 2B-rebuild working file before the partner signs the engagement.
Section 17(5) cureBPO

Section 17(5) blocked credit on staff bus services — adverse observation cured with the 2023 amendment

Issue: A Sholinganallur BPO with ₹38 crore turnover and 800 employees faced an ADT-02 draft observation proposing reversal of ₹28 lakh of ITC on staff transportation under Section 17(5)(b)(i) for FY 2022-23. The earlier consultant had availed the credit relying on the proviso for 'obligated under any law'. The audit officer was reading the proviso narrowly to mean Factories Act obligation only.
Approach: We filed a written submission under Section 65(6) referencing the Tamil Nadu Shops and Establishments Act Section 14 read with the women-safety guidelines issued by the Tamil Nadu Labour Department which mandate transport for women employees on shifts ending after 8 pm. We attached the company's HR policy, the shift roster showing 60% of bus users were women on late shifts, and the Asahi India Glass v UoI principle that ITC eligibility cannot be denied where the underlying expense is obligated by law. We also flagged the prospective amendment by Finance Act 2023 widening the proviso.
Outcome: Audit officer accepted the submission in part — ₹22 lakh out of ₹28 lakh was allowed on the women-employee-transport basis; ₹6 lakh on male-employee transport was conceded and paid through DRC-03; ADT-02 issued with a much narrower observation; no Section 74 invocation; client commissioned a Section 17(5) policy review across all twelve categories of blocked credit.
Section 16(4) defenceApparel exports

Section 16(4) outer date defended at audit for a {{area_name}} apparel exporter

Issue: An apparel exporter in {{area_name}} received an ADT-02 proposing reversal of approximately twelve lakh rupees of input credit availed beyond the Section 16(4) outer date for one financial year prior to the Finance Act 2022 amendment that extended the cut-off to the thirtieth of November.
Approach: The reply traced the legislative chronology, contended that the amendment, while curative, did not displace the earlier dispute, and demonstrated that the impugned credit was availed within the then-applicable cut-off as evidenced by the GSTR-3B filing date stamp. Madras HC writ in Tvl Cooper Diesel Pumps Pvt Ltd v Assistant Commissioner was relied upon.
Outcome: ADT-02 was modified in DRC-01 reduction; demand was confined to one lakh ninety thousand rupees on three invoices that genuinely crossed the cut-off; first appeal under Section 107 was filed on the residual leg with ten per cent pre-deposit.
Cross-chargeInformation technology

Cross-charge defence on inter-branch services at audit for a {{area_name}} multi-state IT firm

Issue: A multi-state IT firm with a head office in {{area_name}} and branches in Karnataka and Maharashtra received an ADT-01 audit alleging missing cross-charge under Schedule I read with Section 25(4) for support functions, with a proposed tax of approximately twenty-eight lakh rupees.
Approach: We documented the head-office cost pool, allocated common-cost segments through the Rule 28 second proviso open-market value route, and demonstrated that all recipient branches were eligible for full input credit, making the cross-charge revenue-neutral. The Karnataka AAR ruling in Columbia Asia Hospitals was placed on record on the salary-cost question.
Outcome: ADT-02 accepted the cross-charge methodology; revenue-neutrality was recognised; the entire twenty-eight lakh rupee exposure was nullified; the methodology was rolled forward into subsequent periods.

GST Audit Support FAQ — Siruseri IT SEZ

Common questions from Siruseri IT SEZ clients. Call 9566-068-468 for specific queries.

Form GST ADT-01 is the audit notice. Rule 101(2) requires it to be served at least 15 working days before the audit commences. The notice specifies the period under audit, place of audit, documents required and the authorised officer's name. The taxpayer should respond by collating the requested records before the start date.
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.
Call or WhatsApp 9566-068-468 with a one-line description of your requirement. We confirm exactly which documents your Siruseri IT SEZ case needs, share a fixed quote upfront, and start once you approve. The first discussion is free.
There are three categories. First, departmental audit under Section 65 conducted by the Commissioner or an authorised officer at the registered person's place of business. Second, special audit under Section 66 ordered by an Assistant Commissioner (with prior approval) and conducted by a Chartered Accountant or Cost Accountant nominated by the Commissioner. Third, self-certified reconciliation through GSTR-9C which a registered person above ₹5 crore aggregate turnover files alongside GSTR-9 from FY 2020-21 onwards.
Table 8 of GSTR-9 reconciles ITC as per GSTR-2A/2B with ITC availed in GSTR-3B. Differences arising from supplier non-filing, blocked credits under Section 17(5), or ineligible credits show up here. Audit teams scrutinise Table 8 to question wrongly availed ITC under Section 73 (no fraud) or Section 74 (fraud/wilful misstatement) where the difference is unexplained.
Our Maduravoyal office on Alapakkam Main Road (opposite KVB Bank) is well connected — from Siruseri IT SEZ, the Siruseri Bus Stop is a handy reference point on the way. That said, GST Audit Support rarely needs a visit; most of it is done online.
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 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.
Yes — we handle GST Audit Support for individuals and businesses across Siruseri IT SEZ (PIN 603103) and nearby Kelambakkam. The work is done end-to-end by our own team, with documents collected online over WhatsApp or email and in-person meetings available at our Maduravoyal and Nerkundram offices. Call 9566-068-468 to begin.
Generally no. Once a Section 65 audit has been completed for a period and ADT-04 has been issued, that period cannot be re-audited under Section 65. Special audit under Section 66 is a distinct power and may be invoked separately if the Assistant Commissioner forms an opinion on incorrect valuation or excess credit. Re-opening a closed Section 65 audit requires fresh material and is exceptional.
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. Along with Siruseri IT SEZ, we serve Kelambakkam and the wider Chennai South belt for GST Audit Support. Wherever you are in this part of Chennai, the process and our 9566-068-468 line stay the same.
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.
Yes. GST audit is GSTIN-wise — each registration has its own books, returns and assessment. A Tamil Nadu GSTIN of a multi-state business is audited separately from its Karnataka or Telangana GSTIN by the respective state's CGST or SGST authority. Records must therefore be maintained GSTIN-wise even where the underlying ERP is consolidated.
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.
Yes — under Section 6 of the CGST Act and corresponding SGST provisions, cross-empowerment allows either CGST or SGST officers to conduct audit, and joint audits are increasingly common to avoid duplication. Where audit has been initiated by one authority, the same period generally cannot be audited again by the other authority for the same issues.
