BLOCK 2 — STATUTORY MAP

BLOCK 3 — COMMENTARY

STATUTORY ARCHITECTURE — SUPERVISORY, NOT ADJUDICATORY

Section 61 establishes the first-line departmental review of self-assessed returns under s. 59. The architecture is deliberately supervisory rather than adjudicatory. The proper officer's role under sub-s. (1) is to identify discrepancies on the face of the records, communicate them to the taxpayer, and solicit an explanation. There is no determination of liability at this stage — substantive determination is reserved for the s. 73 / 74 / 74A stream after scrutiny escalates. This supervisory character is critical to the practitioner response: ASMT-10 is an invitation to reconcile, not an SCN; the appropriate response is documentary reconciliation, not adjudicatory contest.

Three architectural features define s. 61. First, scrutiny is risk-based and discretionary — the proper officer is not obliged to scrutinise every return; the CBIC SOPs (Instructions 02/2022-GST and 02/2023-GST) prescribe risk-based selection parameters and the Department's analytics platforms (BIFA, ADVAIT, GAIN, Antarang) flag returns for scrutiny. Second, the architecture mandates pre-decisional communication and natural justice — the taxpayer must be informed of the discrepancy with sufficient particularity to respond meaningfully, and the minimum 30-day window in sub-s. (3) is the procedural anchor. Third, the architecture provides two distinct closure routes — favourable closure under sub-s. (2) via ASMT-12 where the explanation is acceptable, and escalation under sub-s. (3) where it is not. The Department's choice of escalation route (s. 65 / 66 / 67 / 73 / 74) is itself reviewable for proportionality.

RISK-BASED SELECTION — CBIC SCRUTINY SOP UNDER INSTRUCTIONS 02/2022 AND 02/2023-GST

The CBIC SOP for risk-based scrutiny selection is operationalised through Instruction 02/2022-GST dated 22 March 2022 (for FY 2017-18 and 2018-19) and Instruction 02/2023-GST dated 26 May 2023 (extending the SOP to FY 2019-20 onwards). The SOP identifies the standard discrepancy parameters that drive return selection for scrutiny:

• GSTR-1 vs GSTR-3B turnover mismatch — outward supplies declared in GSTR-1 (supplier-side) do not match the corresponding GSTR-3B Table 3.1 disclosures. Common causes — sales returns reported in GSTR-1 but not in GSTR-3B (or vice versa), B2C aggregations differing, inter-State / intra-State mis-classification.

• GSTR-3B vs GSTR-2A / 2B ITC mismatch — ITC claimed in GSTR-3B Table 4(A) exceeds the auto-populated GSTR-2B. The Department's principal scrutiny parameter for FY 2017-18 through 2020-21 (December 2021). Circular 183/15/2022-GST and Circular 193/05/2023-GST provide the relief framework.

• GSTR-3B Table 4(B) blocked-credit reversal vs s. 17(5) screening — taxpayers not reversing ITC on motor vehicles for passenger transport, food and beverages, construction services for immovable property, employee perquisites, free samples / gifts.

• RCM tax under-reporting in GSTR-3B Table 3.1(d) — GTA, advocates, RBI services, sponsorship etc. supplies that should attract RCM but are not reflected.

• Rule 42 / 43 apportionment shortfall — mixed taxable / exempt operators not undertaking the apportionment exercise; common credits over-claimed.

• 180-day payment-default reversal — invoices unpaid beyond 180 days where the ITC was claimed; second proviso to s. 16(2) compliance.

• E-way bill data vs GSTR-1 turnover — outward supplies reflected in e-way bills exceed GSTR-1 disclosures.

• E-invoice IRP data vs GSTR-1 — for e-invoicing taxpayers, IRP-generated invoices vs GSTR-1 disclosures.

• Annual return GSTR-9 / 9C reconciliation gaps — declared turnover under audited financials vs aggregated monthly returns.

• Late fee and interest computation — short payment of s. 47 late fee or s. 50 interest on shortfall.

Practitioner alignment with the SOP: maintain monthly reconciliations covering each of the above parameters. Where any reconciliation discrepancy is identified pre-emptively, undertake voluntary correction through DRC-03 with interest — this closes the discrepancy before ASMT-10 is issued and substantially reduces scrutiny exposure.

FORM ASMT-10 — ANATOMY OF A VALID SCRUTINY NOTICE

FORM GST ASMT-10 (prescribed under Rule 99) is the operative scrutiny notice. A valid ASMT-10 must contain: (i) the specific tax period(s) covered; (ii) the discrepancy parameter (one or more of the standard parameters listed above); (iii) the quantum of the apparent shortfall (rupees and the underlying computation); (iv) the basis of the apparent discrepancy (which return / data source vs which other); (v) reference to the operative provisions (s. 73 / 74 escalation possibility); (vi) the time-limit for reply (30 days, with extension power); (vii) the proper officer's identification and contact.

The judicial position consistently applied in HC writ proceedings is that a bald ASMT-10 — one that merely says ‘discrepancy noticed; furnish explanation’ without specifying what the discrepancy is — is bad in law. The taxpayer cannot respond meaningfully without knowing the parameter, quantum and basis. Where an ASMT-10 is bald, practitioners can: (i) demand particulars; (ii) approach the HC under Article 226 for direction to furnish proper notice; (iii) preserve grounds for natural-justice defence in any subsequent s. 73 / 74 SCN.

THE 30-DAY REPLY WINDOW UNDER SUB-S. (3)

Sub-s. (3) prescribes a 30-day window for taxpayer's reply, extendable by the proper officer. The window is the minimum natural-justice period. Practitioner experience indicates that the 30-day window is often inadequate for complex discrepancies — reconciliations involving multiple tax periods, supplier confirmations, or banking-trail verification typically require 60-90 days. The proper officer's extension power should be invoked formally — written request citing the complexity, the documentation required, and the reasonable timeline. Where the officer denies extension despite genuine complexity, the practitioner can: (i) file an interim reply preserving rights while comprehensive reconciliation continues; (ii) approach HC for direction.

The 30-day clock runs from the date of communication of ASMT-10. Date of communication is determined per s. 169 (service of notice) — physical service, registered post, email, or portal availability. Portal availability is the most common mode; the date of upload on the common portal is the deemed-service date. Practitioners should monitor the portal regularly to avoid missing the start of the 30-day clock.

DEPARTMENTAL VIEW (CBIC HANDBOOK OF GST LAW AND PROCEDURES, 2024 — CHAPTER III)

The CBIC Handbook (DGGST, updated 30 September 2024) addresses scrutiny in Chapter III (Returns & Scrutiny Thereof, pp 71-100). The Handbook records the Departmental view that scrutiny under s. 61 is a ‘fact-finding exercise’ to verify correctness of self-assessed returns; it is ‘not a substitute for audit or adjudication’. The officer's role is to identify discrepancies, communicate them with sufficient particularity, and seek explanation; where the explanation is acceptable, the matter is closed via ASMT-12.

The Handbook expressly endorses the Circular 183/15/2022-GST and Circular 193/05/2023-GST framework for the GSTR-3B vs GSTR-2A mismatch defence. The Handbook records that the officer is required to consider — and accept — the documentary verification / CA-certificate route in respect of the early-GST years where the matching regime was inoperative. The Handbook also records that escalation under sub-s. (3) is discretionary and proportional — minor or quantum-driven discrepancies generally escalate to s. 73 SCN; complex compliance-pattern issues escalate to s. 65 audit; suspected fraud or evidence of deliberate concealment escalates to s. 67 search and s. 74 SCN.

Practitioner alignment: the Departmental position is operationally taxpayer-friendly in two respects — (i) scrutiny is fact-finding and the officer is expected to engage substantively with the taxpayer's explanation; (ii) the Circular 183 / 193 framework is binding on the officer. The principal area of tension is on the quantum-driven escalation — where the apparent discrepancy is significant in rupee terms but the underlying issue is reconcilable, the Department may escalate to s. 73 SCN despite a substantive ASMT-11 reply. Practitioner response is to engage robustly at the scrutiny stage with comprehensive reconciliation; if escalation occurs, the ASMT-11 record becomes the foundation of the s. 73 / 74 defence.

INTERFACE WITH BHARTI AIRTEL — SELF-ASSESSED RETURNS AND SCRUTINY

The Supreme Court's ruling in Union of India v. Bharti Airtel Ltd., (2021) 54 GSTL 257 (SC); (2022) 4 SCC 328 — holding that GSTR-3B is a self-assessed return that cannot be unilaterally rectified outside prescribed mechanisms — has a direct interface with s. 61 scrutiny. Where the taxpayer's ASMT-11 reply seeks to ‘correct’ an entry in a previously-filed GSTR-3B, the correction must be effected through a subsequent-period GSTR-3B (within the s. 16(4) outer limit of 30 November of next FY for ITC; s. 34(2) for output tax via credit note). The scrutiny notice itself does not permit retrospective rectification of the impugned GSTR-3B — Bharti Airtel forecloses that.

Practitioner consequence: where ASMT-10 raises an apparent shortfall that the taxpayer concedes on substantive review, the correction is via DRC-03 voluntary payment with s. 50 interest, not via re-filing the original return. The DRC-03 closes the discrepancy and an ASMT-12 closure typically follows. Where ASMT-10 raises an apparent ITC over-claim that the taxpayer concedes, the reversal is via subsequent-period GSTR-3B Table 4(B) with s. 50 interest, again followed by DRC-03 if applicable.

CIRCULARS, INSTRUCTIONS AND NOTIFICATIONS

• Notification No. 9/2017-Central Tax dated 28.06.2017 — Enforcement of section 61 effective 01.07.2017. Brought scrutiny of returns into force on day one of the GST regime.

• Rule 99 of the CGST Rules, 2017 dated Statutory — Operative procedural rule for scrutiny under s. 61. Prescribes the notice (ASMT-10), the reply (ASMT-11) within 30 days, and the order on acceptance (ASMT-12). Provides the framework for the proper officer's discretion under sub-s. (3).

• Instruction No. 02/2022-GST dated 22.03.2022 — Standard Operating Procedure (SOP) for scrutiny of returns for FY 2017-18 and FY 2018-19. Comprehensive SOP issued by CBIC to field officers — risk-based selection parameters, template ASMT-10 with annexures showing the discrepancy parameter-wise computation, escalation rules, timelines. Marks the formal commencement of large-scale scrutiny activity for the early-GST years.

• Instruction No. 02/2023-GST dated 26.05.2023 — Extension of scrutiny SOP to FY 2019-20 onwards. Extended the Instruction 02/2022-GST framework to subsequent financial years; emphasised time-bound completion (target — scrutiny of FY 2019-20 to be completed by 31 March 2024) and avoidance of bald or generic notices.

• Circular No. 183/15/2022-GST dated 27.12.2022 — Difference in ITC between GSTR-3B and GSTR-2A for FY 2017-18 and FY 2018-19. Provides the substantive defence framework for the most common scrutiny parameter (ITC mismatch) for the early-GST years. CA-certificate / supplier-confirmation / documentary verification route accepted where the supplier filed GSTR-3B and paid tax. Binding on the proper officer in scrutiny adjudication.

• Circular No. 193/05/2023-GST dated 17.07.2023 — Extension of Circular 183/15/2022-GST framework to FY 2019-20 and FY 2020-21 (up to December 2021). Extends the relief framework to subsequent years where the GSTR-2A / 2B matching regime was still operationally inadequate. Same CA-certificate / documentary verification route applicable.

• Circular No. 31/05/2018-GST dated 09.02.2018 — Proper officer designation for issuance of scrutiny notices under s. 61. Designates the monetary thresholds for proper officer authority — Superintendent (up to Rs. 10 lakh), Asst./Dy. Commissioner (Rs. 10 lakh to Rs. 1 crore), Addl./Jt. Commissioner (Rs. 1 crore to Rs. 25 crore), Commissioner (above Rs. 25 crore). Defective proper-officer authority is a jurisdictional ground.

PROCEDURE — RESPONDING TO ASMT-10

Step 1: Receive and acknowledge ASMT-10 — diary the 30-day clock from communication date

Date of communication is determined per s. 169 — physical / registered post / email / portal availability. Portal upload is the deemed-service date in most cases. Diarise the 30-day expiry and the proper officer's contact for any extension request.

Step 2: Examine ASMT-10 for jurisdictional and substantive completeness

Verify: (i) proper officer authority per Circular 31/05/2018-GST monetary thresholds; (ii) specific tax period(s) covered; (iii) specific discrepancy parameter named; (iv) quantum of apparent shortfall computed; (v) basis of the apparent discrepancy disclosed (which return / data source vs which other). Where the notice is bald or generic, prepare a particulars-seeking response and consider HC writ.

Step 3: Categorise the discrepancy under one of the standard SOP parameters

Match the discrepancy to a SOP parameter — GSTR-1 vs 3B mismatch, GSTR-3B vs 2A ITC mismatch, blocked-credit reversal, RCM under-reporting, Rule 42/43 shortfall, 180-day reversal, e-way bill vs GSTR-1, e-invoice vs GSTR-1, GSTR-9/9C reconciliation, late fee / interest. The categorisation drives the response strategy.

Step 4: Build reconciliation worksheet for each discrepancy

Multi-source reconciliation: GSTR-1 vs GSTR-3B vs books vs GSTR-2A / 2B vs e-way bills vs e-invoice IRP data vs bank statements. Item-wise / invoice-wise reconciliation where the quantum is significant. Working should be self-contained and reproducible.

Step 5: Determine the substantive category of each discrepancy

(a) Apparent / reconcilable — explain through reconciliation with documentary support; no payment required. (b) Genuine error or omission — voluntary correction through subsequent-period return amendment + DRC-03 with s. 50 interest. (c) Contested position — explanation with legal basis, supporting authority, and prior period precedent.

Step 6: For ITC mismatch — invoke Circular 183/15/2022 or 193/05/2023 framework

Identify supplier-wise: (i) supplier filed GSTR-3B and paid tax — obtain CA-certificate from supplier's CA or written confirmation from supplier; document supplier's GSTIN status and return filing record. (ii) Supplier did not file GSTR-3B / did not pay tax — invoke bona-fide-recipient HC line (Suncraft Energy / D.Y. Beathel) where applicable; document invoice, banking trail, GRN, counterparty KYC. (iii) Supplier defunct — alternative documentation strategy.

Step 7: Draft ASMT-11 reply — comprehensive and ground-wise

Ground-wise response addressing each discrepancy parameter: (i) factual reconciliation; (ii) supporting documentary references; (iii) legal basis for the position; (iv) Circular / instruction references; (v) request for personal hearing if substantive contest. Each ground separately addressed; cumulative reconciliation summarised in the conclusion.

Step 8: Annex documentary support

(a) Reconciliation worksheets — clearly labelled, dated, signed. (b) Invoices, GRNs, banking proofs for sample contested items. (c) CA-certificates for Circular 183 / 193 invocations. (d) Supplier confirmation letters. (e) Auditor's / advisor's opinions where applicable. (f) Prior period scrutiny closures (ASMT-12) on similar issues for the same taxpayer or comparable taxpayers.

Step 9: File ASMT-11 reply on the common portal within 30 days

Or seek formal extension before expiry — written request citing complexity, documentation required, and a reasonable extended timeline. Where the discrepancy quantum is substantial (typically Rs. 1 crore+), file an interim acknowledgement reply preserving rights and seek extension for comprehensive response.

Step 10: Track ASMT-12 — closure on acceptance

ASMT-12 is the officer's order accepting the explanation and dropping further action. On receipt, preserve as institutional precedent for future similar scrutinies. Where the officer has not issued ASMT-12 within a reasonable post-reply window (typically 60-90 days), engage with the officer for status.

Step 11: Engage with escalation if it occurs — s. 65 / 66 / 67 / 73 / 74

Where the officer escalates despite a comprehensive ASMT-11 reply: (a) Examine the choice of escalation route for proportionality; (b) Preserve the ASMT-11 reply as the foundation for the subsequent SCN defence; (c) Engage with the next-stage proceeding with full Block 3 commentary defences activated.

Step 12: Voluntary correction through DRC-03 where applicable

For conceded discrepancies — payment of tax + interest under s. 50 through DRC-03 with reference to the ASMT-10. Sub-s. (5) of s. 73 voluntary payment pre-SCN closes the file without penalty. ASMT-12 closure typically follows. Document the rationale for voluntary correction (book error, supplier-side issue resolved, etc.) for institutional record.

CHECKLIST — SCRUTINY (ASMT-10) RESPONSE

WORKED EXAMPLES

Example 61.1 — GSTR-3B vs GSTR-2A ITC mismatch (FY 2018-19) — Circular 183 defence

Example 61.2 — GSTR-1 vs GSTR-3B turnover mismatch — apparent reconciled

Example 61.3 — Genuine error conceded — voluntary correction through DRC-03

Example 61.4 — Bald ASMT-10 — particulars-seeking response and HC writ option

Example 61.5 — Escalation despite ASMT-11 — preserving the defence file for s. 73 SCN

PRACTITIONER PLANNING — INSTITUTIONALISING SCRUTINY READINESS

• Pre-emptive monthly reconciliation discipline. Every taxpayer should reconcile monthly on each of the SOP parameters — GSTR-1 vs GSTR-3B vs books; GSTR-3B vs GSTR-2A / 2B; blocked-credit reversal; RCM Table 3.1(d); Rule 42/43 apportionment; 180-day reversal; e-way bill vs GSTR-1; e-invoice IRP vs GSTR-1. Discrepancies identified pre-emptively can be corrected voluntarily through DRC-03 before any ASMT-10 is issued, substantially reducing scrutiny exposure.

• Maintain institutional ASMT-10 / ASMT-11 / ASMT-12 register. For each scrutiny: parameter, period, quantum, defence strategy, documentary annexures, outcome. Pattern analysis across years identifies systemic issues for corrective action.

• Standardise CA-certificate templates per Circular 183 / 193. For FY 2017-18 to FY 2020-21 (December 2021) ITC mismatch defences, the CA-certificate format from supplier's CA is the operational standard. Standardise the template, the data fields, and the certification protocol so that obtaining certificates is a streamlined process.

• Build supplier-confirmation framework. Where CA-certificate is not feasible (e.g., small supplier without external CA), the supplier's own written confirmation of GSTR-3B filing and tax payment is acceptable. Maintain a counterparty-engagement protocol so that confirmations can be obtained quickly when scrutiny notices arise.

• Train tax / finance team on ASMT-10 response protocol — 30-day clock awareness, jurisdictional checks, SOP parameter mapping, reconciliation discipline, documentary annexure preparation. Periodic mock-scrutiny exercises test team readiness.

• Engage proactively with proper officer where complexity warrants. Where the discrepancy involves multiple periods, complex reconciliations, or substantial documentation, request meeting / clarification with the proper officer early — establishing engagement reduces escalation risk.

• Voluntary correction through DRC-03 is often the cheapest cure. For genuine errors / under-reporting, DRC-03 with s. 50 interest before SCN closes the file under s. 73(5) without penalty. The discipline is to identify the error promptly, pay accurately, and reference the payment in ASMT-11.

• Preserve ASMT-11 record meticulously — it becomes the foundation of any subsequent s. 73 / 74 SCN defence. Sign / date all worksheets; preserve metadata on documentary annexures; maintain version control on drafts.

• For systemic discrepancies — implement system-level corrective measures. Sub-ledger reconciliation discipline, accounting policy refinements, supplier-side compliance reviews. Prevent recurrence so that future scrutiny exposure is minimised.

• Annual review of scrutiny exposure — top-down review of the year's scrutiny activity, outcomes, and lessons. Board-level reporting for institutional taxpayers; partner-level review for professional firms.

LITIGATION DEFENCE — DISPUTES ARISING FROM SCRUTINY PROCEEDINGS

• Bald ASMT-10 — particulars-seeking reply and HC writ. Rule 99 read with s. 61(1) requires the proper officer to inform of discrepancies in a manner enabling meaningful response. Bald notices are reviewable.

• Jurisdictional defect — proper officer outside monetary threshold per Circular 31/05/2018-GST. Quantum-based authority is jurisdictional; cross-threshold issuance is defective.

• 30-day window — extension denied despite genuine complexity. Sub-s. (3) extension power is discretionary but reviewable; HC writ where denial is arbitrary.

• Circular 183 / 193 not engaged. Where ASMT-10 ITC mismatch covers FY 2017-18 to FY 2020-21 (December 2021) and the officer escalates without engaging with the Circular framework, the escalation is procedurally defective. Documentary verification / CA-certificate route is binding on the officer.

• Escalation under sub-s. (3) without explicit unsatisfactory finding. Where the officer issues s. 73 SCN without first finding the ASMT-11 reply unsatisfactory, the escalation is procedurally defective.

• Section 75(7) violation in subsequent SCN — grounds outside ASMT-10 scrutiny scope. The s. 73 / 74 SCN cannot expand beyond the scrutiny parameters; sub-s. (7) bar applies.

• Section 75(4) violation in subsequent SCN — failure to engage with ASMT-11 record. The SCN must address the ASMT-11 grounds; bald escalation ignoring the documentary record is reviewable.

• Pre-SCN voluntary payment under s. 73(5) — bar on further action. Where DRC-03 payment was made on the basis of ASMT-10, subsequent SCN on the same discrepancy is jurisdictionally defective.

• Identical discrepancy in subsequent period — pattern defence. Where the same parameter has been the subject of prior ASMT-12 closure for the taxpayer, the prior closure is institutional precedent; the Department should explain why the same pattern is now being challenged.

• HC writ where escalation involves disproportionate measure — s. 67 search ordered on the basis of an unexplained quantum-driven discrepancy is reviewable for proportionality.
