Key Benefits

What Porur Clients Get

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

Confidential Audit Defence
Audit working papers, ADT-02 findings and reconciliation evidence stored under access-controlled channels. Porur clients' audit data is never shared with third parties or used for cross-marketing.
Audit Closed Without Demand
Where findings are minor and accepted, voluntary payment via DRC-03 closes the audit at ADT-04 stage. Porur clients avoid DRC-01 SCN, Section 73/74 adjudication and penalty escalation.
ITC Defended Against Supplier Default
ITC questioned solely because the supplier did not pay tax to the exchequer is defended with Section 16 compliance evidence and Madras HC precedent — credits retained without reversal.
Table 8 Mismatch Demand Avoided
Table 8 of GSTR-9 — historically the most-litigated audit finding — prepared with line-item backup so audit team has no basis to propose ITC reversal under Rule 36(4) or Section 16(2)(aa).
RCM Demand Pre-Empted
Reverse charge on advocate fees, GTA and director payments — paid in cash, ITC reclaimed in same period, fully documented. Porur clients face no surprise RCM demand at audit stage.
E-Way Bill Compliance Demonstrated
For consignments above ₹50000, e-way bill register with vehicle number and route details produced — Rule 138 compliance evidenced; no penalty under Section 122(1)(xiv) for non-issuance.

GST Audit Support in Porur, Chennai 600116

Approvals, acknowledgements and queries for Porur businesses tie back to the Poonamallee Division, so our GST Audit Support cadence accounts for how that office works. Every Porur engagement we open begins with the basics: PIN 600116, the Poonamallee Division, and the coordinates 13.0382, 80.1565 that anchor the locality. Records we prepare for Porur carry the geo-zone 600xx tag and coordinates 13.0382, 80.1565, which map each submission back to this locality. The 600xx geo-zone covering Porur groups several locality clusters under common administration, keeping documentation expectations predictable.

Freight and foot traffic from the Porur Junction hub pull steady daily commerce through Porur, so there is rarely a quiet filing month in this it corridor and healthcare hub pocket. Working in Porur brings a logistical edge: proximity to Mount Poonamallee Road and the Porur Junction corridor keeps physical document handling fast. Vendors and customers tied to the Porur Junction network show up across the invoice trail we reconcile for Porur GST Audit Support clients. The it corridor and healthcare hub mix of Porur shapes what lands in our workpapers — a blend of it services activity and the commercial pulse around Mount Poonamallee Road.

The education character of Porur commerce influences everything from invoice formats to the supporting documents a GST Audit Support review needs. For a education business in Porur, the GST Audit Support scope is rarely generic; we tailor the checklist to how that sector actually transacts. GST Audit Support for education businesses in Porur hinges on getting the sector's recurring entries right the first time. Mixed education activity across Porur means our GST Audit Support team keeps sector playbooks ready rather than improvising per client.

Document intake for Porur clients runs over WhatsApp, so there is no office visit and no paper shuffle for a GST Audit Support engagement. A Porur client sees the same GST Audit Support cadence each cycle: intake, reconciliation, review, filing, acknowledgement. Every GST Audit Support file we open for Porur is reconciled, reviewed by a qualified practitioner, and archived for seven years. Working papers for Porur GST Audit Support engagements stay archived and retrievable, which makes any later notice or query straightforward to answer.

From the same Porur team we also serve Valasaravakkam and other nearby localities without re-onboarding clients. Coverage from Porur naturally extends to Valasaravakkam, so group entities across the area share one GST Audit Support workflow. We treat Porur and Valasaravakkam as one catchment for GST Audit Support, which keeps documentation and turnaround consistent. A client relocating between Porur and Valasaravakkam keeps the same GST Audit Support file and the same team.

The longer we serve Porur, the more precisely we predict where a GST Audit Support file needs attention. The GST Audit Support mistakes we see most in Porur are avoidable with disciplined intake, which our checklist enforces. Patterns we track for Porur include it services documentation gaps, timing mismatches, and the questions the Poonamallee Division tends to raise. Recurring gaps in Porur it services records are the first thing our GST Audit Support review closes out.

For a new business incorporating in Porur or shifting its principal place of business here, GST Audit Support setup is one of the first things to get right. A startup setting up near Porur Junction in Porur gets a GST Audit Support foundation built for the Poonamallee Division from day one. When a Maduravoyal business expands into Porur, we extend its GST Audit Support setup to PIN 600116 without disruption. Shifting principal place of business to Porur means updating jurisdiction to the Chennai West, and we manage the paperwork end-to-end.

People Also Ask — GST Audit Support in Porur
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 time limit for a Section 66 special audit report?

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

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

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

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

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

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

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

What 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 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.

Audit-to-DRC-01 escalation

Defending Section 74 fraud framing

Where the audit-team recommends Section 74 framing, the registered person's defence focuses on the four elements — fraud, wilful misstatement, suppression of facts, or contravention with intent to evade tax. The Supreme Court's pre-GST jurisprudence on similar language in Central Excise (Pushpam Pharmaceuticals v CCE) and Service Tax (CCE v Mehta and Co) emphasised that mere non-payment or non-disclosure does not amount to suppression with intent; positive indicators of intent are needed. Bona-fide classification errors, computational mistakes, and reasonable interpretation differences are not suppression. Where the SCN frames the case under Section 74, the response should systematically address each of the four elements and rely on the documentary trail showing bona-fide compliance attempts. Pradeep Goyal (DIN requirement) and Kranti Associates (reasoned order) provide procedural safeguards.

Limitation analysis post audit

Section 73(10) provides that the order under Section 73 shall be issued within three years from the due date for furnishing of annual return for the financial year to which the tax not paid or short paid or input tax credit wrongly availed relates; the SCN must be issued at least three months before that date (Section 73(2)). Section 74(10) provides corresponding five-year limitation. For FY 2017-18 GSTR-9 (annual return due 31 December 2018, extended dates apply), the Section 73 limitation expired in late 2021-22 (extended through various Notifications including 9/2023-CT to 31 December 2023 and further), and Section 74 limitation extends to mid-2024 onwards. Audit findings escalated beyond limitation are barred; the registered person should systematically test limitation as part of the SCN defence.

Appellate framework — Section 107 first appeal and beyond

Where the Section 73 or 74 adjudication order under DRC-07 is adverse, the registered person's first appeal lies under Section 107 of the CGST Act before the Joint or Additional Commissioner (Appeals) within three months from the date of communication of the order, extendable by one month for sufficient cause. Pre-deposit of 10% of the disputed tax amount under Section 107(6) is the gateway requirement. Second appeal lies under Section 112 before the GST Appellate Tribunal (now operational with Principal Bench at New Delhi and State / Area Benches notified); the Section 112 pre-deposit is an additional 20% (cumulative 30%). Beyond the Tribunal, appeal lies to the High Court under Section 117 on questions of law, and to the Supreme Court under Section 118. Writ remedy under Article 226 of the Constitution before the Madras High Court is available for jurisdictional infirmities at any stage.

Common audit findings

ITC mismatch between GSTR-2A / 2B and GSTR-3B

The single most common Section 65 audit finding is ITC mismatch — ITC claimed in GSTR-3B Table 4(A) exceeding ITC available in GSTR-2A or GSTR-2B for the corresponding tax period. The post-2019 regulatory tightening — Rule 36(4) initially capping un-uploaded ITC at 20%, then 10%, then 5% (Notification 75/2019-CT, 49/2019-CT, 94/2020-CT trajectory), then Section 16(2)(aa) mandating GSTR-2B as the eligibility baseline (Notification 39/2021-CT effective 1 January 2022) — has progressively tightened the mismatch tolerance to nil. Audit findings on FY 2020-21 onwards typically computes the mismatch quarter-wise; the registered person's defence rests on vendor-wise reconciliation, vendor follow-up correspondence, and the Suncraft Energy bona-fide-buyer principle where applicable.

Reverse-charge under Sections 9(3) and 9(4) — self-invoice gaps

The second-most-common audit finding is missed reverse-charge — supplies where the recipient is liable to pay tax under Section 9(3) (notified categories — GTA without forward-charge election, legal services, sponsorship, services by directors, etc.) or Section 9(4) (supplies from unregistered to registered persons in notified categories for real-estate developers under Notification 07/2019-CT(R) read with 03/2019-CT(R)). Section 31(3)(f) requires the recipient to issue a self-invoice; many registered persons miss this step. The audit-team computes the missed output liability under reverse-charge, the corresponding ITC eligibility (subject to time-limit under Section 16(4)), and the interest under Section 50. Voluntary disclosure via DRC-03 is the standard close-out.

Classification and rate-of-tax disputes

The third-recurrent audit finding is classification and rate-of-tax. The GST rate structure across the rate notifications (Notification 01/2017-CT(R) and amendments, Notification 11/2017-CT(R) for services) contains thousands of HSN-and-SAC line items with rates from nil to 28%; classification borderlines are inherent. Audit-team challenges typically focus on: dual-rate items (5%/12%/18% pharmaceutical formulations, footwear, restaurants), composite versus mixed supplies under Section 8 (where the principal-supply classification determines the rate), and works-contract versus pure services classification. The Section 97 Advance Ruling mechanism offers a forward-looking certainty path; for historical classifications, the response is to cite the CBIC circulars (e.g. Circular 164/20/2021-GST on services classification clarifications) and contemporaneous trade-practice evidence.

Pre-audit preparation

Mock audit by independent reviewer

For high-stake audits (multi-year audits, Section 66 special audit nominations, audits of multi-State enterprises), a mock audit by an independent reviewer — typically a former tax-department officer or a senior Chartered Accountant with audit-defence experience — is a useful preparation step. The mock auditor replicates the audit-team's risk-engine-driven interrogation, identifies weak documentary positions, and recommends remedial steps. The cost of mock audits is justified where the potential audit exposure (tax plus interest plus penalty) materially exceeds the mock-audit fee. Comparative income-tax practice has long used mock-audits for high-stake Section 143(3) scrutiny assessments and Section 142(2A) special audits; the GST extension of this practice is recent but growing.

Document marshalling on receipt of ADT-01

Upon receipt of Form ADT-01, the registered person's first task in the fifteen-day window is structured document marshalling. The recommended sequence is: (i) compile the full year's GSTR-1, GSTR-3B, GSTR-2A / 2B downloads; (ii) compile GSTR-9 and GSTR-9C with the underlying reconciliation working papers; (iii) compile sales register, purchase register and stock register from the accounting system; (iv) compile bank statements and cash-book extracts; (v) compile e-way bill summaries; (vi) compile reverse-charge self-invoice register under Section 31(3)(f); (vii) compile Rule 42 / 43 ITC apportionment working papers; (viii) compile statutory audit and tax audit reports for the corresponding financial year. This structured marshalling enables the audit team to verify systematically and shortens the audit cycle materially.

Internal reconciliation walkthrough

Before the audit-team's arrival, the registered person should conduct an internal reconciliation walkthrough — replicating the audit-team's likely interrogation map. The walkthrough should cover: GSTR-1 outward supply versus books turnover; GSTR-3B Table 3.1 versus GSTR-1 invoice-summary; GSTR-3B Table 4(A) ITC claimed versus GSTR-2A / 2B vendor uploads; GSTR-9 Tables 4 to 8 versus GSTR-1 and GSTR-3B aggregates; GSTR-9C Tables 5, 7, 9, 12 to 14 versus audited financial statements. Any variance identified at the walkthrough is an opportunity for voluntary DRC-03 payment before the audit-team formalises it; voluntary disclosure during the walkthrough phase typically attracts no penalty under Section 73(5) read with Section 73(6).

Glossary

Plain-English glossary for this service

E-way bill audit

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

Place of supply

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

Departmental audit

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

Special audit

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

ADT-01 notice

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

ADT-02 closure

ADT-02 is the form in which the proper officer communicates the audit findings, rights and obligations to the registered person within thirty days of completion of the audit; observations in ADT-02 typically feed into a subsequent Section 73 or Section 74 demand notice if tax has not been voluntarily paid.

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.

By Industry

Industry-specific patterns in Porur

How the local trade mix shapes this — Across Porur, the SME businesses across Ramachandra Nagar SS Colony Lakshmipuram and Kuselar Nagar.

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.
Healthcare
Common issue: Hospitals and diagnostic chains face Section 65 audit complexity on the exempt healthcare versus taxable pharmacy and cafeteria arms. Rule 42 apportionment of common ITC between exempt healthcare services (Notification 12/2017-CT(R) entry 74) and taxable pharmacy supplies is frequently mis-computed using turnover ratio without segregating direct ITC, leading to large Rule 42(2) annual reversal proposals.
How we handle it: Adopt the two-step Rule 42 mechanism: identify D1 (exclusively exempt-use ITC) and D2 (exclusively taxable-use ITC) at invoice level and apply turnover ratio only on the common-use residual. Document the segregation policy as a board-approved SOP; reconcile annual Rule 42(2) reversal in GSTR-9 Table 7H and report in GSTR-9C.
Hospitality
Common issue: Hotel and restaurant chains face Section 65 audit issues on the dual-rate restaurant scheme (5% without ITC versus 18% with ITC for specified non-standalone restaurants per Notification 11/2017-CT(R) as amended). Mid-year scheme-switching, or restaurants within hotels charging room tariff above ₹7,500 per day, frequently leads to ITC eligibility disputes.
How we handle it: Maintain a daily room-tariff register evidencing the ₹7,500 threshold determination month-wise; lock in the restaurant scheme at financial-year start and avoid intra-year switching. For aggregator (Zomato/Swiggy) supplies under Section 9(5), reconcile aggregator-collected output GST against own GSTR-1 disclosure to avoid double-counting allegations.
Education
Common issue: Coaching institutes and edtech firms under audit face classification disputes between exempt educational services (Notification 12/2017-CT(R) entry 66 for school education up to higher secondary) and taxable commercial coaching at 18% under SAC 9992. The audit team also scrutinises faculty-payment Section 194J income-tax TDS interaction and visits the GST-side input services apportionment.
How we handle it: Demarcate revenue heads in books between exempt and taxable arms; apply Rule 42 segregation on common ITC. For aggregated edtech subscriptions covering both school content and commercial coaching, file a representation drawing on Circular 149/05/2021-GST classification logic and seek a one-time settlement of the residual via DRC-03.

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 65(4) timelineHospitality

Three-year audit period closed in 47 days against the Section 65(4) ceiling of 90 working days

Issue: A Chennai hotel group with two GSTINs and ₹26 crore turnover received ADT-01 covering three FYs — 2019-20, 2020-21, 2021-22. The audit was scheduled to commence on 1st February. Section 65(4) caps the audit at 3 months extendable to 6 months by the Commissioner, and from our experience an audit drifting past 90 working days starts attracting deeper questioning as the officer feels pressure to justify findings. We targeted closure in under 60 working days.
Approach: We prepared an audit-management calendar — week 1 records walkthrough, week 2-3 outward and inward supply reconciliation, week 4 ITC reconciliation, week 5 RCM and blocked credit, week 6 working note on observations, week 7 ADT-02 drafting input. We delivered every requested document within 24 hours, maintained a single email chain with the audit officer, and proposed weekly Friday closure meetings. We also flagged our own adverse-finding expectations upfront so the officer was not surprised.
Outcome: ADT-02 was issued on day 47; total observations of ₹4.2 lakh across both GSTINs (mostly room-tariff classification under Notification 14/2022 for the year of the rate change); all accepted and paid through DRC-03; no Section 74 invocation; the office now uses this engagement as a template for audit-calendar planning across all departmental-audit clients.
GSTR-9C defenceHospitality

GSTR-9C reconciliation defended at audit for a {{area_name}} hospitality group

Issue: A hotel group in {{area_name}} above the five-crore aggregate turnover threshold filed GSTR-9C with a turnover reconciliation difference of approximately seven lakh rupees explained as unbilled revenue. The ADT-01 audit team proposed treating the entire difference as suppressed taxable turnover with tax of approximately one lakh twenty-six thousand rupees.
Approach: We anchored the reply on Section 13(2) time-of-supply and demonstrated that the unbilled revenue was an accounting accrual recognised under Ind AS 115 but not a supply within Section 7(1) at the cut-off. Audited financials, room-occupancy registers and the subsequent period invoices were tied line-by-line.
Outcome: ADT-02 accepted the reconciliation; no tax demand was raised on the unbilled revenue head; the matter closed without DRC-01 escalation; turnover reconciliation discipline was carried into the next year.

Why these Porur engagements look the way they do: Closer to Porur, Porur's mix of premium gated residences mid-tier apartments and high-density retail along Trunk Road, which is why for Porur firms managing GST and TDS across high-volume customer-facing and B2B engagements.

Common Questions

GST Audit Support FAQ — Porur

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

Yes. Rule 102 of the CGST Rules deals with special audit under Section 66. Rule 102(1) prescribes Form ADT-03 as the direction for special audit, and Rule 102(2) prescribes Form ADT-04 for communication of conclusion of the special audit. Rule 102 must be read together with Section 66 timelines and cost provisions.
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. Porur businesses with branches outside Tamil Nadu must coordinate branch records to the audit venue.
Absolutely. Most Porur 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.
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.
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.
Our Maduravoyal office on Alapakkam Main Road (opposite KVB Bank) is well connected — from Porur, the Porur Junction is a handy reference point on the way. That said, GST Audit Support rarely needs a visit; most of it is done online.
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.
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.
Our GST Audit Support fees are fixed and shared in writing before any work starts — no hourly billing and no surprises. Pricing depends on the complexity of your case, not your location, so Porur clients pay the same transparent rates as everyone else. See the pricing section above or call 9566-068-468 for an exact figure.
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.
Section 66(2) requires the nominated auditor to submit the special audit report within 90 days of the ADT-03 order. The Assistant Commissioner may, on application by the auditor or the registered person and on reasonable grounds, extend the period by a further 90 days — taking the maximum to 180 days from the ADT-03 order date.
Your engagement is handled by our in-house team led by Ravivarman R (Founder, 15+ years, 500+ engagements), with M. E. Chokkalingam on compliance and S. Jayaprakash on GST matters. You deal with named, qualified people throughout your GST Audit Support — not a call centre.
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.
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.
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.
