Executive Overview
The compliance architecture under the Central Goods and Services Tax (CGST) Act, 2017 relies on a self-assessment tax regime wherein taxpayers independently quantify and discharge their monthly and quarterly tax liabilities in Form GSTR-3B based on outward supplies declared in Form GSTR-1 and inward supplies auto-populated in Form GSTR-2B. To verify the correctness, completeness, and statutory veracity of these self-assessed returns, Parliament armed the tax administration with summary verification powers under Section 61 of the CGST Act, read with Rule 99 of the CGST Rules, 2017, governing the Scrutiny of Returns. For corporate tax heads, compliance officers, and practicing chartered accountants, managing return scrutiny proceedings represents the primary frontline defense against massive demand escalations, penal interest liabilities, and protracted tax litigation.
Far from being a routine clerical exercise, Section 61 scrutiny has evolved into a technologically sophisticated, automated compliance audit driven by advanced data analytics engines operated by the Directorate General of Analytics and Risk Management (DGARM) and business intelligence platforms such as ADVAIT and BIFA. When systemic variances—such as mismatches between GSTR-1 outward tax and GSTR-3B payments, discrepancies between GSTR-2B input tax credit and GSTR-3B claims, or divergences between E-Way Bill turnover and reported sales—cross automated analytical risk thresholds, the Proper Officer issues a formal discrepancy notice in Form GST ASMT-10. The taxpayer is granted a strict statutory window of thirty (30) days to furnish a factual and legal explanation in Form GST ASMT-11.
Failing to handle an ASMT-10 notice with rigorous mathematical and statutory precision triggers immediate administrative escalation. If the explanation furnished is found unsatisfactory or if the taxpayer fails to respond, the Proper Officer is statutorily empowered under Section 61(3) to initiate audit proceedings under Section 65, direct a special forensic audit under Section 66, execute inspection or search under Section 67, or directly institute demand proceedings under Section 73 or Section 74 by issuing a pre-SCN intimation in Form GST DRC-01A followed by a formal Show Cause Notice in Form GST DRC-01. Modern indirect tax practices deploy automated platforms like assureOffice to maintain complete control over scrutiny lifecycles. Within this suite, assureNotice automatically captures portal communications, logs ASMT-10 discrepancy parameters, tracks 30-day response clocks, and structures standardized ASMT-11 replies, while assureTax reconciles multi-year return data to furnish irrefutable transactional defense schedules. This guide provides an exhaustive, practitioner-grade breakdown of Section 61, detailing standard operating procedures (SOPs), mathematical reconciliation models, drop orders in Form GST ASMT-12, and litigation defense strategies.
Comparative Framework: Scrutiny (Sec 61) vs Departmental Audit (Sec 65) vs Adjudication (Sec 73/74)
Tax professionals must clearly distinguish between desk scrutiny of returns (Section 61), comprehensive departmental audits (Section 65), and formal demand adjudication proceedings (Sections 73 and 74). The table below outlines the core legal distinctions across these three enforcement stages under the CGST Act, 2017.
| Statutory Dimension | Scrutiny of Returns (Section 61) | Departmental Audit (Section 65) | Demand Adjudication (Section 73 / 74) |
|---|---|---|---|
| Statutory Nature | Summary desk review of filed returns and portal data to identify discrepancies. | Detailed examination of physical books, ledgers, contracts, and facilities. | Quasi-judicial recovery proceeding to determine unpaid tax, interest, and penalty. |
| Initiating Form | Discrepancy notice in Form GST ASMT-10. | Formal audit notice in Form GST ADT-01 (minimum 15 days notice). | Pre-SCN intimation in Form GST DRC-01A followed by SCN in Form GST DRC-01. |
| Venue of Proceeding | Exclusively desk-based via the online GST Common Portal. | At the place of business of the registered person or at the tax office. | Quasi-judicial personal hearings before the Adjudicating Authority. |
| Statutory Response Window | Strictly thirty (30) days from service (extendable upon request). | Cooperation during audit; audit concluded within 3 months (extendable by 6 months). | Thirty (30) days to reply in Form GST DRC-06. |
| Taxpayer Reply Form | Factual and legal explanation in Form GST ASMT-11. | Submissions, reconciliations, and representations to audit team. | Written statement of defense in Form GST DRC-06. |
| Concluding Order Form | Order accepting explanation in Form GST ASMT-12. | Audit findings report in Form GST ADT-02 within 30 days of completion. | Formal speaking adjudication order in Form GST DRC-07. |
| Power to Create Tax Demand | NO direct demand power. Cannot directly confirm demand under Section 61. | NO direct demand power. Must escalate to Section 73/74 if dues unpaid. | YES. Section 73/74 concludes with legally enforceable tax demand order. |
| Escalation Path if Unresolved | Proper Officer proceeds under Section 65, 66, 67, or issues notice u/s 73/74. | Proper Officer initiates demand adjudication under Section 73 or Section 74. | First Appeal before Appellate Authority under Section 107 within 3 months. |
Detailed Statutory Architecture & Procedural Mechanics
1. Statutory Wording of Section 61 and Rule 99
Section 61(1) of the CGST Act provides: "The proper officer may scrutinize the return and related particulars furnished by the registered person to verify the correctness of the return and inform him of the discrepancies noticed, if any, in such manner as may be prescribed and seek his explanations thereto."
Rule 99 of the CGST Rules, 2017 establishes the operational mechanics governing scrutiny:
- Issuance of Notice (Rule 99(1)): Where any discrepancy is found, the proper officer shall issue a notice to the registered person in Form GST ASMT-10, informing him of such discrepancy, seeking his explanation within thirty (30) days or such further period as may be permitted, and quantifying the amount of tax, interest, and any other amount payable in relation to such discrepancy.
- Filing Explanation (Rule 99(2)): The registered person may accept the discrepancy and pay the tax, interest, and any other amount through Form GST DRC-03 and inform the proper officer in Form GST ASMT-11, or furnish an explanation in Form GST ASMT-11 stating why no discrepancy exists.
- Dropping Proceedings (Rule 99(3)): Where the explanation furnished by the registered person or the payment made is found acceptable, the proper officer shall inform him accordingly in Form GST ASMT-12.
2. The CBIC Standard Operating Procedure (SOP) on Scrutiny
To eliminate arbitrary, selective scrutiny notices and streamline assessment procedures across Central and State tax jurisdictions, the CBIC issued comprehensive Standard Operating Procedures via Instruction No. 02/2022-GST (dated 22nd March 2022) and updated via Instruction No. 01/2023-GST (dated 4th May 2023). Key pillars of the SOP include:
- System-Based Selection: Risk-based automated selection of GSTINs is conducted centrally by DGARM using machine-learning algorithms. Assessing officers cannot randomly pick files for scrutiny without a system-generated analytical flag.
- Indicative Scrutiny Checklist: The SOP details an exhaustive list of operational discrepancy parameters, including:
- Outward taxable turnover in GSTR-1 exceeding GSTR-3B (under-reporting of tax);
- ITC claimed in GSTR-3B exceeding GSTR-2A/2B (ineligible/excess credit claims);
- ITC claimed on invoices where supplier's registration was cancelled retrospectively;
- Non-reversal of proportionate ITC under Rule 42 (exempt supplies) or Rule 43 (capital goods);
- Ineligible ITC claimed on blocked goods/services under Section 17(5);
- Mismatches between E-Way Bill generation values and GSTR-1 declared supplies;
- Discrepancies in Reverse Charge Mechanism (RCM) liabilities declared in Table 3.1(d) vs eligible ITC in Table 4(A)(3);
- Failure to pay interest on delayed return filings under Section 50.
- Strict Batch-Wise Timelines: Officers are mandated to conclude scrutiny within rigorous operational time limits, ensuring that drop orders in Form GST ASMT-12 or escalation notices in Form GST DRC-01A are issued within thirty (30) days of receiving Form GST ASMT-11.
3. Form GST ASMT-10: Anatomy of a Scrutiny Notice
Form GST ASMT-10 is the formal statutory notice communicating discrepancies. It must contain:
- The specific tax period (Financial Year and relevant months) under scrutiny;
- A detailed narrative explaining the exact parameter of discrepancy;
- The statutory provision allegedly violated (e.g., Section 16(2), Section 17(5), Section 50);
- The computational table showing the variance between comparative datasets (e.g., GSTR-1 vs GSTR-3B);
- The quantified proposed tax liability, accompanied by calculated interest under Section 50 and applicable penalty.
Vital Legal Precedent: A scrutiny notice issued in Form GST ASMT-10 does NOT constitute a tax demand order. It is merely a preliminary discrepancy intimation. The Proper Officer has no statutory power to initiate recovery proceedings under Section 79, freeze corporate bank accounts, or attach assets pursuant to Form GST ASMT-10.
4. Form GST ASMT-11: Drafting an Airtight Legal and Factual Defense
The registered person must submit their reply electronically on the GST Common Portal in Form GST ASMT-11 within thirty (30) days from the date of communication of Form GST ASMT-10. An effective ASMT-11 reply must be structured with professional care:
- Factual Reconciliation Matrices: Attach detailed invoice-level and month-wise reconciliation tables explaining why the apparent discrepancy arose (e.g., reporting credit notes in subsequent months, timing differences in export declarations, or capital goods ITC phasing).
- Statutory & Legal Grounds: Cite binding CBIC circulars, retrospective statutory amendments, and High Court precedents demonstrating that the taxpayer's treatment is legally compliant.
- Documentary Proof: Upload certified copies of relevant tax invoices, e-way bills, bank payment statements proving payment to suppliers within 180 days under Rule 37, and CA reconciliation certificates where variances are complex.
- DRC-03 Payment Proof (Where Accepted): If any clerical error is admitted, deposit the admitted tax along with interest under Section 50 via Form GST DRC-03 and attach the generated ARN receipt in Form GST ASMT-11.
5. Form GST ASMT-12: The Concluding Drop Order
Where the Proper Officer is satisfied with the explanation furnished in Form GST ASMT-11 (or verifies that admitted tax dues have been discharged via Form GST DRC-03), the officer is legally mandated under Rule 99(3) to issue a formal order in Form GST ASMT-12. Form GST ASMT-12 explicitly confirms: "The explanation furnished by you has been found to be acceptable and no further action is contemplated by this office in this regard."
The issuance of Form GST ASMT-12 provides absolute statutory closure to the scrutiny proceedings for those specific parameters. An officer cannot subsequently issue a Show Cause Notice under Section 73 on the exact same parameters that were formally accepted and dropped under Form GST ASMT-12, unless new, tangible evidence of fraud or suppression under Section 74 is subsequently uncovered.
6. Escalation to Section 73/74: Form DRC-01A and Form DRC-01
If the taxpayer fails to respond to Form GST ASMT-10 within thirty days, or if the explanation furnished in Form GST ASMT-11 is rejected by the officer, Section 61(3) is triggered. The Proper Officer cannot directly issue an assessment order; the officer must initiate formal adjudication proceedings:
- Pre-SCN Intimation in Form GST DRC-01A: Under Rule 142(1A), the officer issues Part A of Form GST DRC-01A, detailing the proposed tax, interest, and penalty, providing the taxpayer an opportunity to pay or submit partial submissions.
- Formal SCN in Form GST DRC-01: If unresolved, the officer issues a formal Show Cause Notice under Section 73(1) (non-fraud cases) or Section 74(1) (fraud / willful misstatement), accompanied by an electronic summary on the portal in Form GST DRC-01.
- Adjudication Order in Form GST DRC-07: Following written submissions in Form GST DRC-06 and personal hearings, the officer passes a speaking order under Section 73(9) or Section 74(9) uploaded in Form GST DRC-07.
7 In-Depth Practical Case Studies & Numerical Illustrations
Case Study 1: GSTR-1 vs GSTR-3B Outward Tax Mismatch (Timing Difference Defense)
Context & Facts: Bharat Industrial Equipments Ltd received a notice in Form GST ASMT-10 for FY 2023-24 alleging an outward tax shortfall of ₹18,00,000 (IGST). The comparative table in ASMT-10 showed:
- Total Outward Taxable Value in GSTR-1: ₹8,00,00,000 (Tax @ 18% = ₹1,44,00,000).
- Total Outward Tax Discharged in GSTR-3B: ₹7,00,00,000 (Tax Discharged = ₹1,26,00,000).
- Apparent Discrepancy Flagged: Shortfall of ₹18,00,000 tax + Section 50 interest of ₹4,86,000.
Reconciliation & Form GST ASMT-11 Filing:
- Factual Root Cause: The discrepancy was an artificial clerical duplication in GSTR-1, not an actual tax shortfall. No goods moved against the duplicate invoice.
- Corrective Rectification in Table 9 of GSTR-1: Bharat Industrial Equipments amended the duplicate invoice in Table 9 of GSTR-1 for May 2024, neutralizing the outward turnover.
- Drafting Form GST ASMT-11:
- Attach an invoice-by-invoice reconciliation schedule certified by the statutory auditor.
- Attach the shipping bill, customs export manifest, and foreign inward remittance certificate (FIRC) proving only one physical export shipment occurred.
- Attach the GSTR-1 Table 9 amendment filed in May 2024 demonstrating that the clerical duplication stood rectified in the subsequent period.
- Cite CBIC Circular No. 26/26/2017-GST permitting rectification of GSTR-1 reporting errors in subsequent tax periods.
- Outcome: The Proper Officer reviews Form GST ASMT-11, verifies the export shipping bills and Table 9 amendment, and issues a formal drop order in Form GST ASMT-12, extinguishing the proposed demand of ₹22.86 Lakh. The drop order is archived in assureNotice.
Case Study 2: GSTR-2B vs GSTR-3B Input Tax Credit Discrepancy (Supplier Non-Filing Defense)
Context & Facts: Matrix InfraTech Ltd was served an ASMT-10 notice for FY 2023-24 alleging excess ITC availed of ₹24,00,00,000 (₹24 Lakh). The officer noted:
- ITC Available in Auto-Populated GSTR-2B: ₹1,50,00,000.
- ITC Claimed in GSTR-3B Table 4(A)(5): ₹1,74,00,000.
- Excess ITC Flagged: ₹24,00,000 along with 100% penalty under Section 73(9).
Step-by-Step Legal Defense under Section 16(2) and CBIC Circulars:
- Subsequent Compliance Verification: Matrix InfraTech checks the portal status and discovers that both suppliers subsequently filed their pending GSTR-1 and GSTR-3B returns in June 2024, discharging the tax in full to the Government.
- Application of CBIC Circular No. 183/15/2022-GST: Circular 183 provides standard operating procedures for handling GSTR-2A/2B vs GSTR-3B variances:
- Where the variance for a supplier exceeds ₹5,00,000, the taxpayer must obtain a Certificate from a Chartered Accountant or Cost Accountant of the supplier certifying that the supplier actually supplied the goods, issued the tax invoice, included the supply in their GSTR-1, and paid the tax in GSTR-3B.
- Matrix obtains certified CA certificates from the statutory auditors of Apex Steels and Zenon Forgings with unique Document Identification Numbers (UDIN).
- Matrix compiles proof of payment through banking channels establishing that invoice consideration plus GST was paid to the suppliers within 180 days under Rule 37.
- Submission in Form GST ASMT-11: Matrix submits the CA certificates, e-way bills, bank statements, and copies of the suppliers' subsequent GSTR-3B returns.
- Outcome: The Proper Officer accepts the CA certification under Circular 183, drops the scrutiny proceedings, and issues Form GST ASMT-12. Matrix automates this verification protocol using assureTax.
Case Study 3: E-Way Bill vs GSTR-1 Turnover Variations (Bill-To Ship-To Logistics)
Context & Facts: Precision Logistics & Manufacturing Ltd received an ASMT-10 notice stating that total e-way bills generated during FY 2023-24 reflected outward goods movements valued at ₹12,00,00,000 (₹12 Crore), whereas gross turnover reported in GSTR-1 was only ₹8,50,00,000 (₹8.5 Crore). The officer proposed a tax demand of 18% on the ₹3.5 Crore variance (Tax: ₹63,00,000), alleging clandestine sales.
Factual & Legal Decomposition in Form GST ASMT-11:
| E-Way Bill Category | Transaction Value | GSTR-1 Taxable Treatment | Legal Justification & Defense |
|---|---|---|---|
| Direct Outward Sales | ₹8,50,00,000 | ₹8,50,00,000 (Reported in Table 4) | Reconciles 100% with GSTR-1 and GSTR-3B sales records. |
| Movement for Job Work (u/s 143) | ₹1,80,00,000 | Nil (Not a Supply) | Delivery challan issued under Rule 55; reported in quarterly Form GST ITC-04. |
| Bill-To Ship-To Transshipment | ₹1,20,00,000 | Nil (Duplicate E-Way Bill) | Two e-way bills generated for single sale (one for seller, one for transporter). |
| Inter-Branch Stock Transfers | ₹50,00,000 | Nil (Within Same State) | Stock transfer between two factory sheds under single state GSTIN (Rule 55). |
| Total Reconciled E-Way Bills | ₹12,00,00,000 | ₹8,50,00,000 (Reported Sales) | 100% Variance Accounted for under GST Rules |
Precision Logistics attaches Form GST ITC-04 job work returns, transporter delivery challans, and single-GSTIN shed registrations. The officer recognizes that e-way bill generation does not equal taxable supply, and drops the ₹63 Lakh proposed demand in Form GST ASMT-12.
Case Study 4: Input Tax Credit Reversal under Rule 42 (Exempt Supplies Calculation)
Context & Facts: Delta Pharma Chemicals Ltd manufactures both active pharmaceutical ingredients (taxable @ 18%) and bulk basic life-saving drugs (exempt from GST under Notification No. 12/2017-Central Tax). During FY 2023-24, its turnover comprised: Taxable Turnover = ₹15,00,00,000; Exempt Turnover = ₹5,00,00,000 (Total Turnover = ₹20 Crore; Exempt Ratio = 25%). The company availed common input tax credit of ₹40,00,000 on general factory overheads, utilities, and security services. In its annual return (GSTR-9), Delta reversed ₹10,00,000 (25% of ₹40 Lakh) under Rule 42. The Proper Officer issued Form GST ASMT-10 proposing a reversal of ₹25,00,000, arguing that credit should be apportioned based on total gross purchases rather than turnover ratios.
Statutory Analysis of Section 17(2) and Rule 42:
- Under Section 17(2) of the CGST Act, where goods or services are used partly for effecting taxable supplies and partly for exempt supplies, the credit shall be restricted to so much of the input tax as is attributable to the taxable supplies.
- Rule 42 of the CGST Rules establishes the mandatory mathematical formula for reversing common input credit:
Reversal Amount (D1) = (Exempt Turnover / Total Turnover) * Common Input Tax Credit
D1 = (₹5,00,00,000 / ₹20,00,00,000) * ₹40,00,00,000 = 25% * ₹40,00,000 = ₹10,00,000. - The Proper Officer's methodology of apportioning credit on the basis of gross purchases has no legal sanction under the CGST Rules. Rule 42 is strictly turnover-ratio based.
- Outcome: Delta Pharma submits its Rule 42 monthly computational workpapers and GSTR-9 Table 7 disclosures in Form GST ASMT-11. The officer accepts the statutory formula and drops the proposed ₹15 Lakh excess reversal demand under Form GST ASMT-12. Delta maintains these Rule 42 schedules in assureTax.
Case Study 5: Dropping of Proceedings in Form ASMT-12 (Protection from Double Jeopardy)
Context & Facts: In September 2024, Surya Solar Tech Pvt Ltd was issued Form GST ASMT-10 for FY 2022-23 regarding alleged excess credit of ₹14,00,000 on capital goods. Surya Solar submitted an exhaustive factual explanation in Form GST ASMT-11 on 15th October 2024, proving that the capital goods were used exclusively for manufacturing commercial solar inverters and that no depreciation under Section 32 was claimed on the tax component under Section 16(3). The Superintendent scrutinized the documents and issued a formal drop order in Form GST ASMT-12 on 5th November 2024. On 20th January 2025, the newly appointed Assistant Commissioner issued a Show Cause Notice in Form GST DRC-01 under Section 73 proposing the exact same demand of ₹14,00,000 on the same capital goods.
Legal Defense against Repeated Scrutiny:
- Evidentiary Finality of Form ASMT-12: Once the Proper Officer accepts an explanation and issues Form GST ASMT-12 under Rule 99(3), the scrutiny proceeding for those specific parameters reaches formal statutory closure.
- Doctrine of Res Judicata & Administrative Finality: High Courts (including the Madras High Court in Vadivel Pyrotech) have held that revenue authorities cannot reopen concluded scrutiny proceedings on the same facts and parameters without fresh, tangible material or invoking revisional jurisdiction under Section 108.
- Quashing of SCN: Surya Solar files an objection in Form GST DRC-06 annexing the signed Form GST ASMT-12. The Adjudicating Authority drops the SCN, affirming that the issuance of Form ASMT-12 permanently bars issuance of Section 73 notices on identical grounds. Surya archives the drop order in assureNotice.
Case Study 6: Transition from Unresolved ASMT-10 to Form DRC-01A and DRC-01
Context & Facts: Apex Auto Distributors LLP received Form GST ASMT-10 on 10th July 2024 regarding non-reversal of ITC under Rule 37 for invoices unpaid beyond 180 days (disputed tax: ₹32,00,000). Due to internal accounting transitions, the firm failed to file Form GST ASMT-11 within the 30-day statutory window. On 25th August 2024, the Proper Officer closed the scrutiny proceeding and initiated adjudication by issuing Part A of Form GST DRC-01A.
Procedural Progression and Strategic Defense:
- Legal Status of Form DRC-01A: Under Rule 142(1A), Form DRC-01A is an advance pre-SCN intimation providing a final settlement opportunity before a formal SCN is registered.
- Filing Part B of Form DRC-01A: Apex Auto utilizes this window to submit its defense in Part B of Form DRC-01A, demonstrating that out of ₹32 Lakh, ₹22 Lakh had already been paid to vendors within 180 days, while ₹10 Lakh was disputed in commercial court. Apex deposits ₹1,80,000 interest on delayed payments via DRC-03.
- Restricted SCN Issuance: The officer considers Part B of DRC-01A, drops the ₹22 Lakh resolved liability, and issues a formal SCN in Form GST DRC-01 restricted strictly to the remaining ₹10 Lakh disputed amount. Apex defends this balance before the Adjudicating Authority, managing court records via assurePractice.
Case Study 7: Quashing Time-Barred Scrutiny Notices Issued without Form ASMT-10
Context & Facts: An Assessing Officer skipped the Section 61 scrutiny process entirely and directly served a Show Cause Notice in Form GST DRC-01 under Section 73 on Zenon Logistics Ltd for alleged GSTR-3B vs GSTR-1 turnover variances, without issuing any preliminary discrepancy notice in Form GST ASMT-10 or affording an opportunity to explain variances.
Jurisprudential Defense under Article 226:
- Multiple High Courts (including the Gujarat High Court in Fargo Freight and Gauhati High Court in Workmen of Dimakuchi Tea Estate) have held that where the Revenue alleges discrepancies arising from returns filed by the taxpayer, adhering to the statutory procedure under Section 61 read with Rule 99 is mandatory.
- Issuing an SCN directly under Section 73 without issuing Form GST ASMT-10 deprives the taxpayer of the statutory right to furnish an explanation or rectify clerical errors under Section 61(2), violating the principles of natural justice and statutory scheme.
- The High Court quashes the DRC-01 SCN as procedural ultra vires, directing the department to first issue Form GST ASMT-10 and follow the due process of Rule 99 before initiating adjudication.
10-Step Scrutiny Defense & Audit Verification Framework
To systematically manage return scrutiny notices and prevent escalation into coercive adjudication under Section 73 or Section 74, corporate tax departments must execute the following 10-step verification protocol.
| Stage | Procedural Mandate | Statutory Citation | Critical Operational Risk / Audit Trap | assureOffice Workflow Integration |
|---|---|---|---|---|
| Step 1 | Notice Ingestion & Limitation Log | Section 61(1) & Rule 99(1) | Missing portal communications in 'View Additional Notices'; 30-day default. | Capture digital ASMT-10 notices instantly via assureNotice API tracker. |
| Step 2 | Parameter Identification | CBIC Scrutiny SOP Instructions | Treating notice as general demand; failing to isolate specific parameter variance. | Auto-classify scrutiny parameters into standard SOP categories in assureTax. |
| Step 3 | Data Reconciliation Audit | Section 16, 17, 37, 39 | Relying on manual spreadsheets; failing to reconcile invoice-level GSTR-2B data. | Run automated GSTR-1, 2B, 3B, and E-Way Bill reconciliations in assureTax. |
| Step 4 | Vendor Non-Filing Tracking | Circular No. 183/15/2022-GST | Accepting ITC disallowance; failing to obtain CA certificates for vendor defaults. | Generate Circular 183 CA certificate dockets via assurePractice. |
| Step 5 | Admitted Tax DRC-03 Deposit | Rule 99(2) & Section 50 | Failing to pay mandatory Section 50 interest on admitted clerical errors. | Auto-compute Section 50 net cash interest challans via assureTax. |
| Step 6 | Form GST ASMT-11 Drafting | Rule 99(2) CGST Rules | Vague narrative replies; omitting statutory circular citations and reconciliations. | Draft structured legal replies using standardized templates in assureNotice. |
| Step 7 | Extension Petition Protocol | Proviso to Rule 99(1) | Failing to file formal extension request before 30-day clock expires. | Generate automated adjournment applications inside assureNotice. |
| Step 8 | Form GST ASMT-12 Verification | Rule 99(3) CGST Rules | Closing file internally without securing signed Form ASMT-12 drop order. | Track officer docket until formal Form GST ASMT-12 is issued on portal. |
| Step 9 | Form DRC-01A Settlement Defense | Rule 142(1A) CGST Rules | Ignoring Part A intimation; failing to file Part B submissions prior to formal SCN. | Draft Part B settlement submissions via assureNotice. |
| Step 10 | Contingent Liability Accounting | Ind AS 37 & Schedule III | Failing to disclose unresolved scrutiny notices in audited financial balance sheets. | Synchronize disputed tax dockets with balance sheet notes in assureFinancials. |

16 Practical Practitioner FAQs with Authoritative Answers
1. What is the statutory purpose of Section 61 of the CGST Act?
Section 61 empowers the Proper Officer to scrutinize self-assessed returns and related particulars to verify their correctness and inform the registered person of any discrepancies noticed.
2. What form is used by the tax officer to communicate discrepancies under Section 61?
The Proper Officer communicates discrepancies in Form GST ASMT-10 under Rule 99(1) of the CGST Rules, 2017.
3. What is the statutory time limit for replying to Form GST ASMT-10?
Under Rule 99(1), the registered person must furnish an explanation within thirty (30) days from the date of service of the notice, or such further period as permitted by the officer.
4. What form is used by the taxpayer to submit an explanation to Form GST ASMT-10?
The taxpayer submits their factual and legal explanation electronically in Form GST ASMT-11 under Rule 99(2).
5. Can the Proper Officer directly demand tax or initiate recovery under Section 61?
No. Section 61 is an administrative verification mechanism; it does not confer power to pass a demand order or initiate recovery proceedings under Section 79.
6. What form is issued by the Proper Officer when the explanation is accepted?
Where the explanation or payment is found acceptable, the Proper Officer issues an order dropping proceedings in Form GST ASMT-12 under Rule 99(3).
7. What happens if the taxpayer fails to respond to Form GST ASMT-10 within 30 days?
Under Section 61(3), the Proper Officer may initiate audit proceedings under Section 65, direct a special audit under Section 66, initiate search under Section 67, or issue a pre-SCN intimation under Section 73 or 74.
8. Can a taxpayer pay admitted tax discrepancies during scrutiny?
Yes. The taxpayer can accept the discrepancy, pay the tax and mandatory interest under Section 50 voluntarily using Form GST DRC-03, and report the payment ARN in Form GST ASMT-11.
9. What is the CBIC Scrutiny Standard Operating Procedure (SOP)?
Instruction No. 02/2022-GST and Instruction No. 01/2023-GST establish standardized guidelines for system-based selection of returns, specific verification parameters, and strict operational timelines for scrutiny.
10. Can an officer reopen an issue on which Form GST ASMT-12 has already been issued?
No. Issuing Form GST ASMT-12 provides administrative closure on those specific parameters. The officer cannot issue an SCN under Section 73 on identical facts unless fresh evidence of fraud under Section 74 emerges.
11. How are GSTR-2A/2B vs GSTR-3B discrepancies defended under CBIC Circular No. 183/15/2022-GST?
Where the discrepancy exceeds ₹5 Lakh per supplier, the taxpayer must furnish a certificate from the supplier's Chartered Accountant or Cost Accountant certifying that the supplier declared the invoice and paid the tax in GSTR-3B.
12. Is an E-Way Bill variance alone sufficient to create a GST tax demand?
No. E-way bill generation reflects movement of goods, which includes non-supply movements (job work, branch transfers, exhibition goods). A tax demand requires establishing an underlying taxable supply.
13. What form is issued before a formal Show Cause Notice under Section 73/74?
Under Rule 142(1A), the Proper Officer issues Part A of Form GST DRC-01A communicating the proposed tax liability before issuing a formal SCN in Form GST DRC-01.
14. Can an assessing officer issue a Show Cause Notice directly under Section 73 without issuing Form ASMT-10?
