Section 62 — ASSESSMENT OF NON-FILERS OF RETURNS
BLOCK 1 — VERBATIM TEXT
Marginal note — Assessment of non-filers of returns
62. (1) Notwithstanding anything to the contrary contained in section 73 or section 74, where a registered person fails to furnish the return under section 39 or section 45, even after the service of a notice under section 46, the proper officer may proceed to assess the tax liability of the said person to the best of his judgement taking into account all the relevant material which is available or which he has gathered and issue an assessment order within a period of five years from the date specified under section 44 for furnishing of the annual return for the financial year to which the tax not paid relates.
(2) Where the registered person furnishes a valid return within thirty days of the service of the assessment order under sub-section (1), the said assessment order shall be deemed to have been withdrawn but the liability for payment of interest under sub-section (1) of section 50 or for payment of late fee under section 47 shall continue.
[Section 62 enforced w.e.f. 01.07.2017 by Notification No. 9/2017-Central Tax dated 28.06.2017. Operative procedural rule — Rule 100(1) of the CGST Rules, 2017. Forms — GSTR-3A (system-generated notice to non-filer under s. 46 read with Rule 68), ASMT-13 (best-judgement assessment order under s. 62(1)). The 30-day auto-withdrawal under sub-s. (2) was extended to 60 days by Finance Act, 2022, with a further extendable period of 60 days on payment of additional late fee — operationalised through Notification 38/2022-CT (effective dates per subsequent CBIC notifications).]
BLOCK 2 — STATUTORY MAP
ELEMENT OF THE PROVISION
OPERATIVE READING
‘Notwithstanding … section 73 or section 74’
Non-obstante clause displacing the s. 73 / 74 determination route. Section 62 operates independently — the proper officer does not need to first issue a s. 73 / 74 SCN; the best-judgement assessment is the direct route for non-filers. The Department's choice between s. 62 (best-judgement) and s. 73 / 74 (substantive determination) depends on the underlying default — for non-filing, s. 62 is the exclusive route.
‘Where a registered person fails to furnish the return under section 39 or section 45’
Two distinct triggers — (i) failure to furnish a periodic return under s. 39 (GSTR-3B for regular taxpayers; GSTR-4 for composition; GSTR-5 for non-residents; GSTR-6 for ISD; GSTR-7 for TDS; GSTR-8 for TCS); (ii) failure to furnish the final return under s. 45 (GSTR-10) within 3 months of cancellation. The provision does NOT apply to non-filing of GSTR-1 (s. 37) or annual return GSTR-9 (s. 44) — those defaults are governed by other provisions (late fee under s. 47, scrutiny under s. 61).
‘Even after the service of a notice under section 46’
Pre-condition. Section 46 read with Rule 68 prescribes a system-generated notice in FORM GSTR-3A to be served on every defaulter. The GSTR-3A is the procedural precursor — the proper officer cannot directly proceed under s. 62 without first issuing GSTR-3A. Practitioner consequence: where ASMT-13 is issued without a prior GSTR-3A, the assessment is jurisdictionally defective.
‘To the best of his judgement’
The substantive standard. Best-judgement is not arbitrariness — the officer must take into account ‘all the relevant material which is available or which he has gathered’. Pre-GST jurisprudence under s. 23(4) of the Sales Tax laws and s. 144 of the Income-tax Act, 1961 has consistently held that best-judgement requires a reasonable estimate based on available material; bald or speculative quantification is reviewable.
‘All the relevant material which is available or which he has gathered’
Defines the evidentiary base. Available material — the taxpayer's own GSTR-1 (where filed) for outward supplies, GSTR-2A / 2B for inward supplies and ITC exposure, e-way bill data, e-invoice IRP data, prior-period GSTR-3B for trend analysis, banking data under s. 150, third-party information returns. Gathered material — data obtained through s. 70 summons of the taxpayer or third parties, s. 67 inspection where relevant, inter-Departmental data sharing.
‘Issue an assessment order’
FORM GST ASMT-13. The order must — (i) identify the tax period(s) and the return-type defaulted; (ii) reference the prior GSTR-3A; (iii) quantify the tax liability with the underlying computation; (iv) identify the material relied upon; (v) compute interest under s. 50 and late fee under s. 47; (vi) be a speaking order with reasons.
‘Within a period of five years from the date specified under section 44’
Limitation. The 5-year clock runs from the due date of the annual return under s. 44 (typically 31 December of the next FY) for the financial year to which the unpaid tax relates. For FY 2024-25, the annual return due date is 31 December 2025; the s. 62 outer limit for that FY is 31 December 2030.
Sub-s. (2) — ‘furnishes a valid return within thirty days’
Auto-withdrawal route. The principal taxpayer-friendly feature. On filing a valid return — i.e., return filed with full tax payment — within 30 days of ASMT-13 service, the assessment order is deemed to have been withdrawn. (Post-FA 2022, the 30-day window can be extended by a further 60 days on payment of additional late fee.) The taxpayer's best-judgement tax exposure (often inflated) is replaced by the actual self-assessed tax.
‘Liability for payment of interest under s. 50(1) or for payment of late fee under s. 47 shall continue’
Even on auto-withdrawal, the interest at 18% per annum on tax unpaid from the original due date AND the late fee at Rs. 100 / day per Act (with caps) survive. These cannot be avoided by the auto-withdrawal — the auto-withdrawal cures the inflated best-judgement exposure but does not cure the underlying default.
‘Valid return’ — meaning
A return filed in compliance with the prescribed form and with full payment of self-assessed tax (along with interest and late fee). Filing a return without tax payment is invalid; nil filing where actual liability exists is invalid. The Department's portal flags incomplete returns; the auto-withdrawal does not engage unless the return is valid in this sense.
BLOCK 3 — COMMENTARY
STATUTORY ARCHITECTURE — A REVENUE-PROTECTION DEVICE WITH A CALIBRATED ESCAPE VALVE
Section 62 is a revenue-protection device designed to address the practical problem that s. 73 / 74 determination presumes a self-assessed return against which the Department can test for shortfall. Where the taxpayer has not filed any return at all, that comparison base is absent — the Department needs an independent mechanism to crystallise the tax exposure. Section 62 provides that mechanism through best-judgement assessment based on available and gathered material. The non-obstante clause confirms that s. 62 is an independent power, not subordinate to s. 73 / 74.
The architecture has three calibrated features. First, it builds in a structured warning system — the GSTR-3A notice under s. 46 is a mandatory precursor; the taxpayer has at least a 15-day window after GSTR-3A to cure the default before s. 62 is invoked. Second, it provides the auto-withdrawal escape valve under sub-s. (2) — filing a valid return within 30 days of ASMT-13 service deems the assessment withdrawn. This is the most operationally significant feature; it gives the taxpayer a final cure-of-default opportunity before the best-judgement exposure crystallises into recovery. Third, interest and late fee survive the auto-withdrawal under the second limb of sub-s. (2) — ensuring that the taxpayer does not benefit financially from the deferral. The architecture is therefore taxpayer-friendly in form (auto-withdrawal) but revenue-protective in substance (interest + late fee survive).
THE BEST-JUDGEMENT STANDARD — NOT ARBITRARINESS
‘Best-judgement assessment’ is a long-established standard in Indian tax jurisprudence. Under the pre-GST regimes — s. 23(4) of the Madras General Sales Tax Act, s. 17(3) of the U.P. Trade Tax Act, s. 144 of the Income-tax Act, 1961, s. 11A of the Central Excise Act — the courts have consistently held that best-judgement is not unfettered discretion; it is a reasoned estimate based on the material available to the officer. The Supreme Court's classic statement (in the income-tax context but equally applicable here) is that the officer ‘must make an honest estimate of the proper figure of assessment, and for this purpose he must, though strictly not bound to, take into consideration local knowledge and repute in regard to the assessee's circumstances, and his own knowledge of previous returns by and assessments of the assessee, and all other matters which he thinks will assist him in arriving at a fair and proper estimate’ (a paraphrase of the long-settled principle).
Application to s. 62: the proper officer's best-judgement quantum must be (i) based on material — not speculation; (ii) honest — not punitive; (iii) reasoned — capable of being explained in the order. Where the order quantum is significantly higher than the taxpayer's actual liability on subsequent valid return, the auto-withdrawal under sub-s. (2) provides the cure. But where the auto-withdrawal is not invoked and the order operates, the taxpayer's defence at appellate level under s. 107 turns on demonstrating that the quantum is excessive and that the material relied upon did not support the estimate.
Practitioner alignment: where ASMT-13 is operative (no auto-withdrawal invoked), examine the order for: (i) identification of the material relied upon; (ii) the basis of the estimate (averaging, peer-comparison, GSTR-1 / e-way bill extrapolation, etc.); (iii) the rationale for the quantum; (iv) compliance with the speaking-order requirement under s. 75(6). Bald estimates or unexplained multipliers are reviewable.
GSTR-3A NOTICE — THE MANDATORY PRECURSOR UNDER SECTION 46
Section 46 read with Rule 68 of the CGST Rules requires the proper officer to serve a notice in FORM GSTR-3A on every defaulter, calling upon the taxpayer to file the pending return within 15 days. GSTR-3A is system-generated by the common portal once a return is overdue — typically within a few days of the due date for GSTR-3B (20th of next month for regular taxpayers) or for the final return GSTR-10 (3 months from cancellation).
Practitioner consequence: the GSTR-3A is the cheapest cure-of-default opportunity. The 15-day window after GSTR-3A service permits the taxpayer to file the pending return without facing best-judgement quantum. Most taxpayers should treat GSTR-3A as the latest possible action point — file the return promptly with tax + interest + late fee. Where genuine inability prevents 15-day filing (e.g., system outages, banking failures), document the circumstances and engage with the proper officer; an extension is theoretically possible but practically rare.
Jurisdictional consequence: where ASMT-13 is issued without a prior GSTR-3A, or where the GSTR-3A 15-day window has not expired before ASMT-13 issuance, the best-judgement assessment is jurisdictionally defective. The natural-justice precursor has not been satisfied. Practitioners should preserve the GSTR-3A service record (or absence thereof) as the foundational defence document.
AUTO-WITHDRAWAL UNDER SUB-S. (2) — THE 30-DAY CURE WINDOW
Sub-s. (2) provides the most operationally significant taxpayer-friendly feature in the section. Filing a valid return within 30 days of ASMT-13 service deems the assessment order to be withdrawn. ‘Valid return’ means a return filed in the prescribed form with full payment of self-assessed tax. The auto-withdrawal is automatic — no separate application or order is required; the system-level effect is that the best-judgement quantum is replaced by the actual self-assessed tax.
The FA 2022 amendments (operationalised through subsequent notifications) extended the auto-withdrawal window — the original 30 days can be extended by a further 60 days on payment of additional late fee, giving a total potential window of approximately 90 days. The extended window is a practitioner-friendly safety net for cases where the 30-day timeline is genuinely insufficient.
Interest and late fee survive — the second limb of sub-s. (2) is explicit. Interest under s. 50(1) at 18% per annum runs from the original due date of the return (e.g., 21st of the next month for GSTR-3B) to the actual date of payment. Late fee under s. 47 is Rs. 100 per day per Act (Rs. 200 total for CGST + SGST; Rs. 100 for IGST) subject to per-return caps and periodic waiver notifications under s. 128. Where the late fee accumulates substantially due to long-delayed filing, practitioners should track active s. 128 waiver notifications — periodic notifications cap late fee for delayed annual returns, delayed GSTR-3B for specified periods, and other categories.
INTERFACE WITH BHARTI AIRTEL — SELF-ASSESSED RETURN ON CURE
On invocation of auto-withdrawal under sub-s. (2), the taxpayer files the pending GSTR-3B as a self-assessed return. The Bharti Airtel SC principle applies — the GSTR-3B filed is binding self-assessment; subsequent rectification is not available except through the prescribed mechanisms (subsequent-period correction within the s. 16(4) / s. 34(2) outer limits). Practitioner consequence: the cure-of-default GSTR-3B must be accurate. Errors in the cure GSTR-3B cannot be corrected by re-filing — they must be addressed through subsequent-period adjustments per Bharti Airtel.
FIVE-YEAR LIMITATION UNDER SUB-S. (1) AND CALCULATION
The 5-year clock runs from the due date of the annual return under s. 44 for the financial year to which the unpaid tax relates. The s. 44 due date is typically 31 December of the next FY (post-FA 2022; was earlier 30 September of the second next FY). For FY 2017-18, the s. 44 due date was extended multiple times due to portal operationalisation; for subsequent years the standard 31 December of next FY applies (subject to extensions).
Computation table — for FY 2017-18: s. 44 due date 30 June 2019 (extended); s. 62 outer limit 30 June 2024. For FY 2018-19: s. 44 due date 31 December 2020 (extended); s. 62 outer limit 31 December 2025. For FY 2019-20: s. 44 due date 31 March 2021 (extended); s. 62 outer limit 31 March 2026. For FY 2020-21 onwards: standard 31 December of next FY due date; s. 62 outer limit five years thereafter. Section 168A FA 2020 force-majeure time extensions (Notifications 9/2023-CT and 56/2023-CT) further extended the limitation for early years; their constitutional validity is contested in pending writ proceedings. Practitioners should track the operative outer limits per the active extension notifications.
DEPARTMENTAL VIEW (CBIC HANDBOOK OF GST LAW AND PROCEDURES, 2024 — CHAPTER IV)
The CBIC Handbook (DGGST, updated 30 September 2024) addresses non-filer assessment in Chapter IV (Assessment, pp 101-114). The Handbook records the Departmental view that s. 62 is the ‘exclusive route’ for non-filers — the non-obstante clause displacing s. 73 / 74. The Handbook emphasises three operational points: (i) GSTR-3A under Rule 68 is the mandatory precursor; ASMT-13 cannot issue without GSTR-3A having been served and the 15-day cure window having expired; (ii) the best-judgement quantum must be ‘reasonable and based on relevant material’ — the Department's MIS systems pull GSTR-1 data, e-way bill data and third-party banking data to support the quantum; (iii) the auto-withdrawal under sub-s. (2) is the structural taxpayer-friendly feature and the Department expects most ASMT-13 cases to be cured through filing within 30 / 90 days.
The Handbook also addresses the late-fee waiver framework under s. 128 — periodic notifications cap or waive late fee for specified categories of delayed returns. For FY 2017-18 to FY 2020-21 the late-fee accumulation was particularly severe due to the prolonged disputes; multiple waiver notifications mitigated the impact. The Handbook records that the Department applies the operative waiver notification automatically — practitioners should verify the waiver application in any cure-of-default scenario.
Practitioner alignment: the Departmental position is operationally clear and predictable — non-filing leads to GSTR-3A within days of due date; ASMT-13 if uncured within 15 days; auto-withdrawal if cured within 30 / 90 days. The principal area where practitioner attention is needed is the best-judgement quantum — Department's MIS-driven quantums are often inflated relative to actual liability, and the auto-withdrawal cure is the operative answer.
PROSECUTION EXPOSURE — INTERFACE WITH s. 132
Wilful non-filing of returns where tax has been collected from buyers but not deposited can also attract prosecution under s. 132(1)(d) — ‘collects any amount as tax but fails to pay the same to the Government beyond a period of three months from the date on which such payment becomes due’. Where the tax-collected-but-not-deposited quantum exceeds Rs. 5 crore, the offence is cognizable and non-bailable under s. 132(5). The Department's choice between s. 62 best-judgement and s. 132 prosecution is fact-driven — pure non-filing without tax collection is a s. 62 case; collection without deposit is a s. 132 case in addition to s. 62.
Practitioner alignment: for clients facing non-filing exposure where tax has been collected, the priority is rapid cure of default — file the pending return with full tax payment to remove the s. 132 prosecution trigger. Voluntary disclosure under s. 73(5) framework is the appropriate route. Coordination between civil (s. 62) and criminal (s. 132) defences is critical.
CIRCULARS, NOTIFICATIONS AND OPERATIVE PROVISIONS
• Notification No. 9/2017-Central Tax dated 28.06.2017 — Enforcement of section 62 effective 01.07.2017. Brought best-judgement assessment of non-filers into force on day one of the GST regime.
• Rule 68 of the CGST Rules, 2017 dated Statutory — Notice to non-filers under s. 46 — FORM GSTR-3A. System-generated notice issued by the common portal when a return is overdue. 15-day cure window. Procedural precursor to ASMT-13 under s. 62.
• Rule 100(1) of the CGST Rules, 2017 dated Statutory — Operative procedural rule for s. 62 — FORM GST ASMT-13. Prescribes the best-judgement assessment order form. The order must identify the period, return-type, material relied upon, tax computation, interest and late fee.
• Section 46 read with Rule 68 dated Statutory — Notice to defaulters in FORM GSTR-3A — 15-day window. The mandatory precursor to s. 62. ASMT-13 cannot issue without GSTR-3A having been served and the 15-day window having expired without cure.
• Section 47 — Late fee dated Statutory — Rs. 100 / day per Act (CGST + SGST = Rs. 200 / day; IGST Rs. 100 / day). Survives auto-withdrawal under sub-s. (2). Periodic waiver notifications under s. 128 cap late fee for specified categories.
• Section 50(1) — Interest dated Statutory — 18% per annum on tax unpaid from original due date. Survives auto-withdrawal. Runs from due date of the return to actual date of payment.
• Section 132(1)(d) — Prosecution for tax collected but not deposited beyond 3 months dated Statutory — Cognizable and non-bailable where quantum exceeds Rs. 5 crore. Where the non-filing default involves collection without deposit, parallel s. 132 exposure arises; rapid cure of default is the priority.

• Section 168A force-majeure extensions dated Effective per Notifications 9/2023-CT, 56/2023-CT — Extension of s. 62 limitation for early years. Constitutional validity contested. Practitioners should track operative outer limits per the active extension notifications.
PROCEDURE — RESPONDING TO GSTR-3A AND ASMT-13
Step 1: On GSTR-3A receipt — diary the 15-day window
Date of communication via portal upload is typically the deemed-service date. Diarise the 15-day expiry. Identify the pending return-type (GSTR-3B period; GSTR-4 quarter; GSTR-10 final; etc.) and the reason for non-filing (system error, banking failure, internal delay, dispute).
Step 2: Compile correct figures for the pending return — pre-emptive cure
Gather invoices, GSTR-2B, books, e-way bills; compute output tax, RCM, ITC, blocked credits, net liability accurately. Pre-emptive cure within the 15-day window avoids ASMT-13 entirely and minimises overall cost (interest + late fee only).
Step 3: File the pending return within 15 days of GSTR-3A
Through the common portal. Pay tax with interest under s. 50(1) at 18% per annum from the original due date. Late fee under s. 47 — verify active s. 128 waiver notifications and apply the operative cap.
Step 4: If 15-day window lapses without cure — anticipate ASMT-13
The Department's MIS will trigger ASMT-13 within days. Prepare for the 30-day cure window under sub-s. (2). Compile the correct figures urgently.
Step 5: Receive ASMT-13 — examine for jurisdictional completeness
(a) Prior GSTR-3A service verified; (b) 15-day window verified as expired; (c) proper officer authority per Circular 31/05/2018-GST; (d) tax period(s) identified; (e) return-type identified; (f) tax quantum with computation; (g) interest and late fee computation; (h) material relied upon disclosed; (i) speaking-order quality.
Step 6: Determine the 30-day auto-withdrawal feasibility
Where books are ready and the return can be filed within 30 days of ASMT-13 service with full tax payment — invoke auto-withdrawal under sub-s. (2). Filing the valid return is the cure; no separate application needed.
Step 7: Where 30 days is insufficient — invoke extended 60-day window
Post-FA 2022, the auto-withdrawal can be extended by a further 60 days (cumulative 90 days from ASMT-13) on payment of additional late fee per the operative notification. Engage with the additional late-fee computation and pay through the cash ledger.
Step 8: File the cure-of-default return with full tax payment
Through the common portal. (i) Self-assess output tax + RCM + ITC + blocked credits + apportionment for the period. (ii) Pay tax + interest from original due date + late fee through cash / credit ledger. (iii) On submission, the common portal records the auto-withdrawal — ASMT-13 is system-deemed withdrawn. Preserve the portal acknowledgements.
Step 9: Confirm auto-withdrawal status on portal
Verify that the ASMT-13 status reflects as ‘withdrawn’ post-filing. Where the system has not auto-updated, engage with the proper officer for manual confirmation.
Step 10: If 30 / 90 days lapse — engage with ASMT-13 on merits
Where the auto-withdrawal window has been missed, ASMT-13 becomes operative. Recovery under s. 78 / 79 commences. Remedies: (a) Rectification under s. 161 within 3 months for errors apparent on record; (b) Appeal under s. 107 within 3 months of ASMT-13 communication, with 10% pre-deposit of disputed tax (capped Rs. 25 crore post FA 2024).
Step 11: At appellate stage — challenge best-judgement quantum on merits
Substantive defence: (i) demonstrate the actual tax liability based on books / records / contemporary documentation; (ii) compare with the ASMT-13 quantum; (iii) show that the best-judgement quantum is excessive and not based on relevant material; (iv) cite the pre-GST jurisprudence on best-judgement standard. Procedural defence: (i) absence of prior GSTR-3A; (ii) defective service of ASMT-13; (iii) absence of disclosed material; (iv) speaking-order deficiencies.
Step 12: Coordinate with prosecution exposure under s. 132(1)(d)
Where the non-filing default involves tax collected from buyers but not deposited within 3 months, the s. 132(1)(d) prosecution trigger may be present. Rapid cure of default — file the return with full payment — removes the trigger. For high-quantum (Rs. 5 crore+) cases, evaluate anticipatory bail and coordination with criminal counsel.

WORKED EXAMPLES
Example 62.1 — Auto-withdrawal: best-judgement quantum vs actual liability
ASMT-13 at Rs. 35 lakh; actual liability Rs. 6 lakh; 30-day cure
Facts: M/s Vega Trading Pvt. Ltd. failed to file GSTR-3B for February 2025. The portal generated GSTR-3A on 6 April 2025 (return due 20 March 2025; 15-day post-due cure window expired without filing). On 25 April 2025, the proper officer issued ASMT-13 assessing tax at Rs. 35 lakh — based on average prior 6 months' GSTR-3B output tax of Rs. 30 lakh per month + 17% upward adjustment for prior under-reporting allegations.
Step 1: Step 1 — 30-day cure window from ASMT-13 service on 25 April 2025 → 24 May 2025 expiry.
Step 2: Step 2 — Compile correct figures. February 2025 was a low-activity month for Vega — outward taxable supply Rs. 40 lakh; output tax @18% = Rs. 7.20 lakh; eligible ITC Rs. 5.50 lakh; RCM tax on GTA Rs. 30,000. Net tax payable = Rs. 7.20 + 0.30 - 5.50 = Rs. 2 lakh; plus the wrongly-claimed ITC reversal of Rs. 4 lakh would actually bring net to Rs. 6 lakh.
Step 3: Step 3 — Interest under s. 50(1). From 21 March 2025 to 22 May 2025 (expected payment date) = 62 days. Interest = Rs. 6 lakh × 18% × 62 / 365 ≈ Rs. 18,400.
Step 4: Step 4 — Late fee under s. 47. From 21 March 2025 to 22 May 2025 = 62 days. Late fee = 62 × Rs. 100 / day per Act × 2 (CGST + SGST) = Rs. 12,400; subject to per-return cap (typically Rs. 5,000 per Act under active waiver) = Rs. 10,000 total.
Step 5: Step 5 — File GSTR-3B for February 2025 on 22 May 2025 with full payment — tax Rs. 6 lakh + interest Rs. 18,400 + late fee Rs. 10,000 = Rs. 6.28 lakh.
Step 6: Step 6 — ASMT-13 auto-withdrawal under sub-s. (2). Portal updates the assessment status as ‘withdrawn’ post-filing.
Result: Saving from auto-withdrawal: Rs. 35 lakh ASMT-13 quantum replaced by Rs. 6 lakh actual liability — Rs. 29 lakh saved. Total cost Rs. 6.28 lakh. The 30-day cure window is the single most valuable safeguard in the section. Practitioner discipline — establish standing procedure to identify GSTR-3A receipt within 24 hours and initiate cure-of-default protocol immediately.
Example 62.2 — Extended 90-day cure window with additional late fee
Complex multi-period non-filing — extended cure under FA 2022 framework
M/s Lyra Manufacturing failed to file GSTR-3B for 5 consecutive months (April-August 2025) due to a prolonged internal accounting system outage. ASMT-13 was issued on 15 December 2025 for the aggregate non-filed period, assessing tax at Rs. 1.50 crore based on prior-period averages. Actual liability on careful computation Rs. 75 lakh. The 30-day cure window expires 14 January 2026. Lyra needs more time to complete the accounting system migration, books verification, and reconciliation for the 5 months. Lyra invokes the FA 2022 extended cure — files an application for additional 60 days with payment of additional late fee per the operative notification. Extended window expires 15 March 2026. On 10 March 2026, Lyra files all 5 GSTR-3Bs with: (i) total tax Rs. 75 lakh; (ii) interest from each respective original due date to actual payment date (cumulative approximately Rs. 9 lakh); (iii) late fee per return per the active s. 128 waiver caps (cumulative approximately Rs. 50,000). Total cost approximately Rs. 84.50 lakh. ASMT-13 deemed withdrawn. Saving from extended window — Rs. 1.50 crore - Rs. 84.50 lakh = Rs. 65.50 lakh.
Example 62.3 — 30-day window missed; appeal under s. 107
Cure-of-default missed; ASMT-13 operative; appeal route
M/s Cassiopeia Pvt. Ltd. — proprietor was unwell during the entire 30-day cure window and missed the auto-withdrawal opportunity. ASMT-13 for July 2025 at Rs. 45 lakh became operative on 30 September 2025. Recovery proceedings under s. 78 / 79 commenced; bank account garnishee notice DRC-13 issued. Defence path: (i) File APL-01 appeal under s. 107 within 3 months of ASMT-13 communication (i.e., by 30 December 2025); 10% pre-deposit of disputed tax = Rs. 4.5 lakh paid through DRC-03. (ii) Recovery proceedings stayed automatically under s. 107(7) on pre-deposit. (iii) Substantive appeal grounds: actual liability on contemporaneous books was Rs. 7 lakh — best-judgement quantum of Rs. 45 lakh is excessive and not based on relevant material; procedural ground — speaking-order deficiencies in ASMT-13; documentary evidence — books, invoices, banking records for July 2025 produced. (iv) Personal hearing under s. 75(4) requested. (v) Appellate Authority hearing — quantum reduced to Rs. 7 lakh on merits; remand declined per s. 107(11) no-remand rule; substantive order in APL-04 for Rs. 7 lakh + interest + 10% penalty. Even at appellate level, the actual-liability defence is the principal substantive ground; documentation discipline is the foundation.
Example 62.4 — Jurisdictional defect: ASMT-13 without GSTR-3A
ASMT-13 issued without prior GSTR-3A — natural-justice defect
M/s Polaris Power received ASMT-13 on 5 May 2025 for non-filing of GSTR-3B for March 2025. On verification, Polaris finds that no GSTR-3A had been served — neither on portal nor by email / post. Section 46 read with Rule 68 mandates GSTR-3A as the procedural precursor; ASMT-13 cannot issue without GSTR-3A having been served and the 15-day window having expired. Defence: (i) Establish absence of GSTR-3A — portal screenshot showing no GSTR-3A notification for the period; email / postal records showing no service; RTI application to the proper officer's office confirming absence. (ii) File ASMT-11-style preliminary representation to the proper officer pointing out the procedural defect and seeking withdrawal of ASMT-13. (iii) Where the officer does not withdraw — HC writ under Article 226 seeking quashing of ASMT-13 on natural-justice / Rule 68 grounds. (iv) HCs across States have consistently quashed ASMT-13 orders issued without prior GSTR-3A; the procedural defect is fatal. (v) Outcome — ASMT-13 quashed; the Department may re-initiate via proper GSTR-3A → 15-day window → ASMT-13 sequence.
Example 62.5 — Tax collected but not deposited — coordinated s. 62 and s. 132 defence
Non-filing with collection-without-deposit — coordinated defence
M/s Centaurus Services Pvt. Ltd. had collected output tax of Rs. 8 crore from clients in respect of services rendered during October-December 2024, but failed to file GSTR-3B for those months and did not deposit the collected tax. The non-deposit period exceeded 3 months; the cognizable threshold of Rs. 5 crore under s. 132(5) is crossed. The Department issues ASMT-13 in March 2025 + a parallel s. 132(1)(d) prosecution notice with s. 69 arrest authorisation. Defence — coordinated civil and criminal: (i) Immediate cure of default — file GSTR-3Bs for October-December 2024 with full payment of Rs. 8 crore tax + interest (Rs. 30 lakh approximately) + late fee (Rs. 75,000 approximately). The cure-of-default removes the s. 132(1)(d) substantive trigger (tax now deposited). (ii) ASMT-13 auto-withdrawal under sub-s. (2). (iii) Parallel s. 132 defence — Commissioner sanction verification; anticipatory bail under Cr.P.C. s. 438; cooperation with investigation; demonstrate absence of intent to evade (genuine business cash-flow difficulties; not deliberate retention). (iv) Compounding under s. 138 — FA 2023 range 25-100% of tax; assess cost-benefit vs prosecution defence cost. (v) Coordination between civil and criminal counsel throughout. Outcome — civil cured; criminal compoundable; cost approximately Rs. 8 crore tax + Rs. 30 lakh interest + Rs. 2-8 crore compounding (depending on negotiation). Practitioner alignment — for tax-collected-not-deposited cases, rapid cure removes the criminal substantive trigger; coordinated defence is non-negotiable.
PRACTITIONER PLANNING — STANDING PROCEDURE FOR NON-FILER EXPOSURE
• Implement GSTR-3A monitoring discipline. The portal generates GSTR-3A within days of return-overdue status. Daily portal-status review by the GST in-charge; immediate escalation on GSTR-3A receipt. The 15-day post-GSTR-3A cure window is the cheapest cure path — file the return immediately with tax + interest + late fee, avoiding ASMT-13 entirely.
• Pre-emptive book-vs-return reconciliation at month-end. Where the return cannot be filed by due date due to delayed reconciliation, identify the gap pre-emptively and file with best-available figures + voluntary correction route. Avoids the trigger for non-filing default.
• Standing 30-day cure response protocol. On ASMT-13 receipt, internal escalation to senior tax / finance leadership within 24 hours; books verification commenced; correct figures compiled; tax + interest + late fee discharged; cure return filed before 30-day expiry. Standard operating procedure documented and team-trained.
• Cash-flow planning for cure-of-default. The cure return requires full tax payment in cash — for large-quantum cases, advance cash-flow planning is needed. Banking facility / overdraft / fresh capital infusion may be required. Engagement with banking partner ahead of cure filing is part of the protocol.
• Coordinate with active s. 128 waiver notifications. Late fee accumulation can be substantial for long-delayed returns; waiver notifications under s. 128 cap or waive late fee for specified categories and periods. Track active waivers; apply the operative cap.
• Identify section 132(1)(d) exposure where tax has been collected. For service providers / B2C suppliers who collect tax from buyers, non-filing carries dual exposure — s. 62 civil + s. 132 criminal. Rapid cure of default removes the criminal trigger. Where Rs. 5 crore+ collected-not-deposited, treat as a high-priority matter with coordinated counsel.
• Train the finance / tax team on the 30 / 90 day cure architecture. Quarterly refresher; new-hire induction; mock-cure exercises. The team's ability to execute the cure quickly is the principal mitigant for non-filer exposure.
• Annual audit of return-filing discipline. Top-down review of any non-filer episodes — root cause, system-level corrective measures, training requirements. Board-level reporting for institutional taxpayers.
• For QRMP taxpayers — distinct discipline. Non-filing of PMT-06 (monthly payment) does not trigger s. 62 (which is for s. 39 / 45 returns); but non-filing of quarterly GSTR-3B does. Distinguish the two streams in compliance discipline.
• For composition taxpayers — GSTR-4 (annual) is the s. 39 return. CMP-08 quarterly statement is not directly a return for s. 62 purposes but Department's MIS treats persistent non-filing of CMP-08 as a compliance failure that may trigger s. 29 cancellation. Comprehensive compliance discipline across both streams.
LITIGATION DEFENCE — DISPUTES UNDER SECTION 62
• Absence of prior GSTR-3A. Section 46 read with Rule 68 mandates GSTR-3A as the procedural precursor. ASMT-13 without GSTR-3A is jurisdictionally defective. HC writ relief is consistently granted; the procedural defect is fatal.
• Defective service of GSTR-3A. Where GSTR-3A is shown to have been issued but not properly served (per s. 169 modes), the 15-day cure window has not commenced. ASMT-13 issued before proper service is premature.
• Defective service of ASMT-13. Same s. 169 framework. Where ASMT-13 is not properly served, the 30-day cure window has not commenced and recovery proceedings are jurisdictionally premature.
• Bald or unreasoned best-judgement quantum. The substantive standard from pre-GST jurisprudence — best-judgement is a reasoned estimate based on relevant material — is consistently applied. Bald multipliers or unexplained quantums are reviewable. Speaking-order requirement under s. 75(6) applies.
• Quantum challenge on merits. Actual liability on contemporaneous books / records compared with ASMT-13 quantum. Where the gap is substantial and the underlying records support a lower figure, appellate reduction is the standard outcome.
• Failure to disclose material relied upon. Sub-s. (1) requires the officer to use ‘all the relevant material … available or … gathered’. Where the order does not disclose the material relied upon, the natural-justice ground is engaged.
• 30 / 90-day cure window missed — pre-deposit and appellate route. Standard s. 107 appeal with 10% pre-deposit; substantive defence on quantum; procedural defences preserved.
• 5-year limitation breach. Where ASMT-13 is issued beyond the s. 62(1) outer limit (5 years from s. 44 due date) and no valid extension applies, the order is jurisdictionally defective.
• Section 168A extensions — constitutional validity. Notifications 9/2023-CT and 56/2023-CT extending the limitation are contested in pending writ proceedings; preserve grounds where the operative outer limit depends on these extensions.
• Late fee — waiver notification not applied. Periodic s. 128 waivers cap late fee; where the operative cap is not applied, file rectification under s. 161 / appeal under s. 107.
• Section 132(1)(d) prosecution defence (where applicable). Rapid cure of default removes the substantive trigger; anticipatory bail; compounding under s. 138; civil and criminal counsel coordination.
