People Also Ask — GST Audit Support in KK Nagar
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 does Form ADT-02 set out at the close of a departmental audit?

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

What is Form ADT-03 in GST?

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

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

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

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

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

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 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

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.

Personal hearing

Personal hearing under sub-section (4) of Section 75 is the opportunity granted by the proper officer or appellate authority to the registered person to present his case orally. Three adjournments at the option of the person sought to be heard are permitted on sufficient cause. Denial of personal hearing is a procedural infirmity.

Cross-examination

Cross-examination is the right of the registered person, as part of the opportunity of being heard, to examine the witnesses or officers whose statements are relied on against him in adjudication. The right is sought through a written application during personal hearing. Denial is a recognised ground in first appeal under Section 107.

Reasons to believe

Reasons to believe is the jurisdictional threshold under sub-section (1) of Section 67 for inspection, search and seizure, and is invoked also in the special-audit context. The reasons must be recorded in writing and must rest on tangible material; subjective satisfaction without material is open to challenge.

Commissioner approval

Commissioner approval is the substantive condition for invoking special audit under sub-section (1) of Section 66. The proposing officer not below the rank of Assistant Commissioner must obtain prior approval of the Commissioner before issuing the direction in ADT-03. Approval without recorded reasons is open to challenge.

By Industry

Industry-specific patterns in KK Nagar

How the local trade mix shapes this — KK Nagar businesses operate where the cluster of healthcare, education, residential businesses that defines KK Nagar's commercial fabric.

Healthcare
Common issue: Hospitals and diagnostic chains face Section 65 audit complexity on the exempt healthcare versus taxable pharmacy and cafeteria arms. Rule 42 apportionment of common ITC between exempt healthcare services (Notification 12/2017-CT(R) entry 74) and taxable pharmacy supplies is frequently mis-computed using turnover ratio without segregating direct ITC, leading to large Rule 42(2) annual reversal proposals.
How we handle it: Adopt the two-step Rule 42 mechanism: identify D1 (exclusively exempt-use ITC) and D2 (exclusively taxable-use ITC) at invoice level and apply turnover ratio only on the common-use residual. Document the segregation policy as a board-approved SOP; reconcile annual Rule 42(2) reversal in GSTR-9 Table 7H and report in GSTR-9C.
Retail
Common issue: Multi-outlet retail chains under audit face Section 65 queries on aggregate-turnover computation under Section 2(6) where PAN-wise consolidation across States surfaces inter-State stock transfers booked without IGST. Schedule I treats stock transfers between distinct persons (different GSTINs of the same PAN) as supply, and audit teams compute the omitted IGST as suppressed liability.
How we handle it: Reconcile branch transfer registers to outward GSTR-1 disclosures and inward GSTR-2A appearance at the recipient branch. Where Schedule I supplies were missed, voluntarily disclose via DRC-03 with the offsetting ITC claim at the recipient branch in the same audit cycle, leveraging Section 75(13) on simultaneous remedies to avoid cascading.
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.
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.
Education
Common issue: Edtech aggregators under audit face Section 9(5) e-commerce-operator scrutiny where multiple tutors supply through the platform. Notification 17/2017-CT(R) and subsequent amendments deem the platform liable for specified services; classification gaps between educational and commercial coaching at the platform level surface as suppressed-output exposures.
How we handle it: Demarcate platform revenue between exempt educational services (where applicable under Notification 12/2017-CT(R)) and taxable commercial coaching. For Section 9(5) coverage, confirm whether the specific service falls within the deemed-supplier framework via Circular 167/23/2021-GST and subsequent FAQs; build a CBIC-circular-anchored audit-defence file.
Case Studies

Anonymised engagements we have handled

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

Stock varianceFMCG distribution

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

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

Section 65 audit on credit-note disclosure defended for a {{area_name}} consumer electronics distributor

Issue: A consumer electronics distributor in {{area_name}} received an ADT-01 audit on alleged non-disclosure of Section 34 credit notes of approximately twenty-nine lakh rupees in GSTR-1 within the September-following outer date, with a proposed deemed-supply demand of approximately five lakh twenty thousand rupees.
Approach: We mapped each credit note against the recipient acknowledgement of ITC reversal under Section 34(2) proviso, demonstrated that the recipient had reversed the credit in the corresponding GSTR-3B, and showed that the supplier-side credit note adjustment was therefore permitted. Original tax invoices and recipient confirmations were filed.
Outcome: ADT-02 accepted the credit-note treatment; the five lakh twenty thousand rupee demand was dropped; the recipient-acknowledgement template was rolled forward as standard practice.
Section 15(3) discountsConsumer durables

Section 65 audit on Section 15(3) discount treatment defended for a {{area_name}} consumer durables seller

Issue: A consumer durables seller in {{area_name}} received an ADT-01 audit on alleged non-deduction of post-supply discounts of approximately twenty-two lakh rupees from taxable value, with a proposed differential tax demand of approximately three lakh ninety-six thousand rupees.
Approach: We mapped each post-supply discount against the Section 15(3)(b) twin condition of pre-supply agreement linkage and recipient ITC reversal proof. Recipient credit-note acknowledgements and the underlying dealership agreement were filed. CBIC Circular 92/11/2019 on discounts and Circular 105/24/2019 (subsequently rescinded) were placed in context.
Outcome: ADT-02 accepted the discount treatment; the three lakh ninety-six thousand rupee differential was dropped; the dealership agreement clauses were tightened to capture future discount-conditions formally.
Diya AgenciesHardware trading

Diya Agencies principle extended at Section 65 audit for a {{area_name}} hardware trader

Issue: A hardware-trading firm in {{area_name}} faced an ADT-01 audit covering two financial years with proposed credit reversal of approximately nine lakh rupees on supplier-side default. The audit team treated GSTR-2B absence as conclusive without testing the recipient's documentary trail.
Approach: We anchored the reply on the Madras High Court ratio in the Tvl Diya Agencies matter, which holds that supplier-side lapses cannot, in isolation, defeat recipient credit absent an enquiry against the supplier and a recorded finding on the recipient's good faith. Supplier-level enquiry trails and banking-channel payment evidence were filed.
Outcome: ADT-02 confined the reversal to seventy-eight thousand rupees relating to two genuinely missing suppliers; the residual eight lakh rupees was preserved; the matter closed within five months without DRC-01.

Why these KK Nagar engagements look the way they do: Closer to KK Nagar, the business activity radiating outward from Kalaignar Karunanidhi Nagar and nearby commercial pockets, which is why for the professional and salaried population of KK Nagar navigating personal-tax and home-office GST.

Common Questions

GST Audit Support FAQ — KK Nagar

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

Rule 101 of the CGST Rules operationalises Section 65. Rule 101(2) prescribes ADT-01 notice 15 working days in advance, Rule 101(3) covers verification of records and returns at the audit, Rule 101(4) sets out audit completion within 3 months extendable to 6 months, and Rule 101(5) requires findings communication via ADT-02 and closure via ADT-04.
Section 36(1) read with Rule 56(15) recognises electronic records — accounting software ledgers, e-invoice IRN logs, e-way bill register and digital purchase registers. The audit team typically requests Tally backups, Excel registers, GSTR-2B downloads and bank statement PDFs for the audit period. Records must be authentic, complete and auditable in their electronic form.
Yes — 600078 (KK Nagar) is well within our service area. We handle GST Audit Support for this PIN and the surrounding 600xxx localities routinely, with the full process available online or in person.
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.
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.
Yes. Beyond GST Audit Support, we cover GST, income tax, TDS, company and LLP registrations, digital signatures, audits and finance documentation — so KK Nagar clients keep all their compliance under one roof. Ask us about anything on 9566-068-468.
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).
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.
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 KK Nagar clients pay the same transparent rates as everyone else. See the pricing section above or call 9566-068-468 for an exact figure.
Yes. Rule 102 of the CGST Rules deals with special audit under Section 66. Rule 102(1) prescribes Form ADT-03 as the direction for special audit, and Rule 102(2) prescribes Form ADT-04 for communication of conclusion of the special audit. Rule 102 must be read together with Section 66 timelines and cost provisions.
Where the taxpayer accepts the findings in ADT-02, the short-paid tax along with interest under Section 50 (and any applicable penalty) is voluntarily paid through Form DRC-03 on the GST portal. Reference to the audit ARN is recorded in DRC-03. The proper officer then passes the closure order in ADT-04 noting that the matter has been settled.
Our main office is at Plot No. 6, Alapakkam Main Road (opposite KVB Bank), Maduravoyal – 600095, with a branch at No. 22 Reddy Street, Nerkundram – 600107. Both are an easy reach from KK Nagar, and a third office at Nolambur is opening shortly. Most clients, though, never need to visit.
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.
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.
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.
Yes. Section 66(6) requires the registered person to be given an opportunity of being heard on any material gathered in the special audit which is proposed to be used in any proceeding. After the report, if the proper officer initiates a Section 73 or 74 demand based on the findings, the registered person can contest the demand through the regular SCN-reply-adjudication-appeal route.
