BLOCK 3 — COMMENTARY

STATUTORY ARCHITECTURE — TWO TRIGGERS, ONE PROCESS, MANDATORY HEARING

Section 63 fills a structural gap in the assessment architecture. Section 62 (non-filer assessment) presupposes a registered person who has failed to file returns — there is a GSTIN, there are s. 46 GSTR-3A notice triggers, there is an ASMT-13 mechanism. But what of persons who were liable to be registered and never were — or whose registration was cancelled and who continued supplying? These persons are outside the GSTIN-based assessment ecosystem; s. 62 cannot reach them; s. 73 / 74 presupposes a registered taxpayer with self-assessed returns. Section 63 is the bespoke mechanism — independent of s. 73 / 74 (non-obstante clause) and providing a best-judgement framework specifically calibrated for unregistered-liable persons.

Three architectural features define s. 63. First, the two substantive triggers — (a) failure-to-register where liable; (b) continued activity post s. 29(2) cancellation — represent distinct defaulter classes that the Department's intelligence and analytics platforms identify through cross-reference: GSTR-2A signals from registered taxpayers claiming ITC on supplies from unregistered persons; banking-trail data under s. 150; e-way bill data showing inter-State movement by unregistered persons; third-party information returns disclosing high-value transactions. Second, the mandatory hearing under the proviso — distinguishing s. 63 from s. 62 — reflects the structural reality that the unregistered person has not received any GSTIN-based precursor notice; the hearing is the principal natural-justice safeguard. Third, the 5-year limitation tied to the s. 44 annual return due date creates a meaningful but not unlimited departmental window — unregistered exposure crystallises within 5 years of the relevant FY's annual return due date.

TRIGGER A — FAILURE TO OBTAIN REGISTRATION WHERE LIABLE

The substantive analysis of Trigger A requires precise application of ss. 22 and 24 read with the relevant notifications. Section 22 prescribes the aggregate-turnover threshold — Rs. 40 lakh for exclusive-goods suppliers in normal States; Rs. 20 lakh for others (including services or mixed); Rs. 10 lakh for special-category States (Manipur, Mizoram, Nagaland, Tripura). The threshold is computed at PAN-level across all States — a person with Rs. 25 lakh turnover in State A and Rs. 25 lakh in State B has aggregate turnover Rs. 50 lakh and is registrable in both States.

Section 24 prescribes 12 categories of compulsory registration regardless of threshold: (i) inter-State taxable supply (with the Rs. 20 lakh carve-out for services under Notification 10/2017-IT); (ii) casual taxable persons; (iii) persons required to pay tax under reverse charge; (iv) ECO required to collect TCS under s. 52; (v) non-resident taxable persons; (vi) persons required to deduct tax under s. 51 (TDS); (vii) persons supplying goods or services on behalf of other registered taxable persons (agents); (viii) ISD; (ix) persons supplying through ECO; (x) every ECO; (xi) every person supplying OIDAR services from outside India to a non-taxable online recipient; (xii) any other category notified by Government.

Practitioner alignment: for any Trigger A defence, the substantive recomputation of aggregate turnover under s. 2(6) is foundational. The Department's quantum often includes items that should be excluded — e.g., supplies on which RCM is paid by the recipient (already taxed at the recipient end); inter-State supplies of services up to Rs. 20 lakh per Notification 10/2017-IT; sale of land (Schedule III); services by employee to employer in course of employment (Schedule III); etc. Each exclusion must be documented.

TRIGGER B — CONTINUED ACTIVITY POST-CANCELLATION UNDER s. 29(2)

Section 29(2) provides for suo-motu cancellation by the Department in specified circumstances: (a) registered person has contravened provisions of the Act or Rules; (b) regular taxpayer has not furnished returns for a continuous period of six months; (c) composition taxpayer has not furnished returns for three consecutive tax periods; (d) voluntary registrant has not commenced business within six months from registration; (e) registration was obtained by means of fraud, wilful misstatement or suppression of facts.

Where the registration is cancelled but the person continues to make taxable supplies, Trigger B activates. The substantive default is operating without a valid GSTIN — invoices issued post-cancellation are not valid tax invoices; recipient cannot claim ITC; the unregistered person nevertheless collected tax (or should have) and is liable to deposit. Section 63 captures this exposure.

Practitioner alignment: Trigger B cases are often layered with multiple defaults — cancellation revocation under s. 30, late filing of pending returns, late fee under s. 47, interest under s. 50, and the s. 63 best-judgement quantum for the post-cancellation period. Strategic response — pursue revocation of cancellation under s. 30 in parallel where the 30-day (extendable to 90-day) window is still alive; this restores the GSTIN retrospectively and converts the Trigger B exposure into a s. 62 non-filer exposure with auto-withdrawal possibility. Where the revocation window has lapsed, fresh registration is necessary; the s. 63 exposure for the gap period is computed separately.

MANDATORY HEARING UNDER THE PROVISO — STRUCTURAL DISTINCTION FROM SECTION 62

The proviso's mandatory hearing requirement is the principal procedural safeguard for the unregistered person. Section 62 has no express hearing precondition (the s. 46 GSTR-3A precursor serves the natural-justice role for registered non-filers); s. 63's proviso fills that gap for unregistered persons. The proviso is jurisdictional — an ASMT-15 order passed without affording opportunity of being heard is bad in law.

Operational sequence: (i) ASMT-14 SCN issued — must contain specifics of trigger, period, quantum, material; (ii) typical reply window of 15 days for written reply; (iii) personal hearing on request OR where adverse decision contemplated; (iv) ASMT-15 order — must record compliance with the hearing requirement and engage with the reply on merits.

Practitioner alignment: in every Trigger A / B defence, examine the ASMT-14 for: (i) specificity of allegations; (ii) adequate reply window; (iii) hearing offered. Where any element is absent, the proviso safeguard is engaged. ASMT-15 orders without recorded hearing are reviewable in s. 107 appeal or HC writ on natural-justice grounds.

ITC ON INPUTS IN STOCK AT REGISTRATION — SECTION 18(1)(a) INTERFACE

Where the Trigger A defaulter subsequently obtains registration — voluntarily or under departmental pressure — s. 18(1)(a) permits the new registrant to take ITC of input tax paid on inputs held in stock, inputs contained in semi-finished goods, and inputs in finished goods on the day immediately preceding the date from which the person becomes liable to pay tax. The credit is subject to a 1-year time-limit from the date of invoice.

For the s. 63 best-judgement quantum, this ITC is a substantive offset against the gross tax exposure. Practitioner alignment: on Trigger A defence, simultaneously pursue: (i) recomputation of gross tax on outward supplies for the relevant periods; (ii) s. 18(1)(a) ITC on inputs in stock at the date of becoming liable (FORM GST ITC-01 filing within 30 days of becoming liable, supported by CA-certificate if claim exceeds Rs. 2 lakh); (iii) net liability — gross output tax less s. 18(1)(a) ITC.

INTERFACE WITH PROSECUTION — SECTION 132(1)(xi) AND (xii)

Failure to obtain registration where liable is a prosecution-eligible offence under s. 132(1)(xi) — ‘is liable to be registered under this Act but fails to obtain registration’. Furnishing false information regarding registration is under s. 132(1)(xii). Where the underlying quantum of tax evasion exceeds the s. 132(1) thresholds (Rs. 1 crore / Rs. 2 crore / Rs. 5 crore based on the punishment tier), criminal prosecution exposure arises in addition to the s. 63 civil assessment.

Practitioner alignment: for Trigger A cases with substantial quantum, the civil s. 63 exposure and the criminal s. 132 exposure must be addressed in parallel. Voluntary registration with payment of accumulated tax + interest under s. 73(5) / 74(5) framework is the most effective mitigation — voluntary disclosure pre-SCN closes the s. 73 / 74 civil track (where applicable) and significantly reduces s. 132 prosecution risk. Compounding under s. 138 (25-100% of tax post FA 2023) remains available where criminal exposure persists.

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

The CBIC Handbook (DGGST, updated 30 September 2024) addresses unregistered-person assessment in Chapter IV (Assessment, pp 101-114). The Handbook records the Departmental view that s. 63 is the ‘exclusive route’ for unregistered persons — s. 73 / 74 cannot reach them because there is no self-assessed return to test against. The Handbook emphasises four operational points:

• Detection of unregistered-liable persons primarily through GSTR-2A flag-data — where a registered recipient claims ITC against a supplier PAN that has no GSTIN, the Department's BIFA / ADVAIT analytics flag the supplier for s. 63 inquiry.

• Banking-trail data under s. 150 from banks reporting high-value transactions — the Department cross-references PAN-level banking inflows with GSTIN-status to identify potential threshold-breach defaulters.

• Trigger B detection is operationally simpler — the Department's MIS lists all suo-motu-cancelled GSTINs; cross-reference with subsequent banking activity, ECO-platform sales, or e-way bill data identifies continued activity.

• Best-judgement quantum is built up from available material — typically extrapolating from limited GSTR-2A / banking / e-way bill signals to the full operational period. The Handbook records that quantums are conservative where signals are limited but can be aggressive where multiple signals converge.

On procedural posture, the Handbook expressly emphasises the mandatory hearing under the proviso — officers are instructed to issue ASMT-14 SCNs with sufficient particularity and to grant personal hearing on request. ASMT-15 orders passed without hearing are flagged for departmental review and risk being reversed in appeal. Practitioner alignment: the Departmental position is operationally consistent — preserve the hearing safeguard as the primary procedural defence; pursue substantive defence (threshold recomputation, exclusions, s. 18(1)(a) ITC offset) on the merits.

CIRCULARS, NOTIFICATIONS AND OPERATIVE PROVISIONS

• Notification No. 9/2017-Central Tax dated 28.06.2017 — Enforcement of section 63 effective 01.07.2017. Brought best-judgement assessment of unregistered persons into force on day one of the GST regime.

• Rule 100(2) of the CGST Rules, 2017 dated Statutory — Operative procedural rule for s. 63. Prescribes FORM GST ASMT-14 (show-cause notice) and ASMT-15 (best-judgement order). Operationalises the mandatory hearing under the proviso.

• Section 22 read with Schedule of thresholds dated Statutory — Aggregate-turnover thresholds for compulsory registration. Rs. 40 lakh exclusive-goods suppliers (normal States); Rs. 20 lakh others; Rs. 10 lakh special-category States. PAN-level aggregation under s. 2(6).

• Section 24 — Compulsory categories dated Statutory — 12 categories of compulsory registration regardless of threshold. Inter-State (with services carve-out); casual; RCM; ECOs / TCS; NR; TDS; agents; ISDs; OIDAR; Government-notified.

• Notification No. 10/2017-IT dated 28.06.2017 — Rs. 20 lakh threshold for inter-State service supply. Critical carve-out from s. 24(i) — service providers making inter-State supply have a Rs. 20 lakh aggregate-turnover threshold rather than zero-threshold compulsory registration.

• Section 29(2) dated Statutory — Suo-motu cancellation grounds for Trigger B. Five grounds — contravention, return non-filing (6 months regular / 3 quarters composition), non-commencement, fraudulent registration. Cancellation under this sub-section is the precursor to Trigger B.

• Section 30 dated Statutory — Revocation of cancellation. 30 days (extendable up to 90 days) from cancellation order; restores GSTIN retrospectively if granted. Strategic alternative to Trigger B s. 63 exposure where the window is still alive.

• Section 18(1)(a) dated Statutory — ITC on inputs in stock at date of becoming liable. Available to Trigger A defaulters on subsequent registration. FORM GST ITC-01 within 30 days; CA-certificate above Rs. 2 lakh.

• Section 132(1)(xi) and (xii) dated Statutory — Prosecution offences for failure to register / false registration information. Parallel criminal exposure for Trigger A defaulters; coordinated defence with s. 63 civil assessment.

• Section 138 — Compounding dated Statutory — 25-100% of tax post FA 2023. Structured exit from prosecution; preserves criminal track closure for high-quantum cases.

• Suguna Cutpiece Centre v. Appellate Deputy Commissioner (ST), (2022) 59 GSTL 73 (Madras HC) dated — — Restoration of cancelled GSTIN on compliance cure — proportionality principle. Persuasive authority for Trigger B cases where revocation under s. 30 is being pursued; the HC line consistently supports restoration on cure of underlying defaults.

PROCEDURE — RESPONDING TO ASMT-14 AND DEFENDING AT ASMT-15

Step 1: Receive ASMT-14 and examine for substantive trigger

Identify whether the SCN is Trigger A (failure-to-register) or Trigger B (continued activity post-cancellation). Each requires distinct substantive defence. Trigger A turns on threshold / category disputes; Trigger B turns on cancellation validity and continuation.

Step 2: Verify procedural completeness of ASMT-14

(a) Proper officer authority per Circular 31/05/2018-GST monetary thresholds; (b) substantive trigger articulated with specifics (which threshold / category / cancellation reference); (c) period identified; (d) quantum with computation; (e) material relied upon disclosed; (f) reasonable reply window (typically 15 days); (g) hearing offered.

Step 3: For Trigger A — recompute aggregate turnover and category eligibility

Independent verification of s. 2(6) aggregate turnover at PAN level across all States. Exclude items wrongly included by Department — RCM-paid supplies, inter-State services within Rs. 20 lakh (Notification 10/2017-IT), Schedule III non-supplies, exempt supplies of dwelling, etc. Verify s. 24 category claims — was the person genuinely supplying inter-State / casual / through ECO etc.?

Step 4: For Trigger B — verify the cancellation and continued activity

(a) Cancellation order under s. 29(2) — date, ground, validity; (b) revocation window under s. 30 — still alive or lapsed; (c) continued activity post-cancellation — invoices, banking, e-way bills; (d) magnitude of continued activity.

Step 5: For Trigger B with live revocation window — pursue revocation in parallel

FORM GST REG-21 application under s. 30 within 30 days of cancellation (extendable to 90 days). Cure underlying defaults — file all pending returns with tax + interest + late fee. On revocation, GSTIN is restored retrospectively; Trigger B exposure converts to a s. 62 non-filer exposure with auto-withdrawal possibility.

Step 6: Compute the substantive tax exposure

Gross output tax on supplies during the relevant period (at applicable rate; verify rate per Notifications 1/2017, 11/2017-CT(R) and rate-change history). Apportion CGST + SGST for intra-State; IGST for inter-State. Less s. 18(1)(a) ITC on inputs in stock at date of becoming liable (Trigger A). Less any other lawful credits. Net liability comparison with Department's ASMT-14 quantum.

Step 7: Compute interest under s. 50

From the date the tax would have been due if registration was held (typically 20th of next month for regular taxpayer GSTR-3B due date) to the actual / expected date of payment. 18% per annum.

Step 8: Compute late fee and penalty exposure

Late fee under s. 47 for returns that should have been filed if registered (subject to active s. 128 waiver caps). Penalty under s. 122(1)(xi) for failure to register — up to Rs. 10,000 or tax evaded, whichever higher (subject to s. 73 / 74 framework if applicable for additional penalty).

Step 9: Pursue voluntary registration and disclosure

Where the Trigger A default is genuine, pursue voluntary registration in parallel with ASMT-14 response. Voluntary registration with full tax + interest + late fee payment within s. 73(5) framework can close the matter pre-SCN. Section 132(1)(xi) prosecution risk significantly reduced by voluntary cure.

Step 10: Draft ASMT-11-style reply to ASMT-14

Comprehensive reply covering: (i) factual position with documentary support; (ii) substantive grounds — threshold recomputation, category clarification, exclusions; (iii) ITC offset under s. 18(1)(a); (iv) procedural grounds — defects in ASMT-14 if any; (v) request for personal hearing.

Step 11: Attend personal hearing — invoke proviso safeguard

Mandatory under the proviso. Engage substantively — produce documents, address officer queries, articulate the legal grounds. Maintain hearing record — date, persons present, points discussed, documents furnished.

Step 12: Engage with ASMT-15 — appeal or compliance

(a) On favourable order — preserve as institutional precedent. (b) On adverse order — appeal under s. 107 within 3 months with 10% pre-deposit (cap Rs. 25 crore); substantive defence on merits. (c) On partial relief — selective compliance with appeal on contested portion.

Step 13: Coordinate prosecution defence under s. 132 where applicable

For high-quantum Trigger A cases (especially where Rs. 5 crore+ tax exposure): (i) coordinate civil and criminal counsel; (ii) anticipatory bail under Cr.P.C. s. 438; (iii) compounding under s. 138 evaluation; (iv) voluntary disclosure documentation.

PRACTITIONER PLANNING — INSTITUTIONAL REGISTRATION-COMPLIANCE DISCIPLINE

• For all clients — monitor aggregate turnover monthly against operative thresholds. Maintain a PAN-level turnover dashboard aggregating supplies across States. Trigger registration application well in advance of threshold crossing — typically when turnover reaches 80-85% of threshold to allow for processing time.

• Identify s. 24 compulsory categories at engagement. For clients in inter-State supply, casual taxable activity, ECO platform usage, RCM exposure, ISD structures, TDS / TCS counterparty status — registration is compulsory regardless of threshold. Verify each category carefully.

• For inter-State service providers — verify Notification 10/2017-IT applicability. The Rs. 20 lakh threshold applies to service-only inter-State suppliers; it does not apply to goods. Mixed-supply scenarios require careful analysis.

• Maintain banking trail discipline for all clients. The Department's analytics are driven by banking-data cross-reference with GSTIN-status. For clients with substantial banking inflows that could trigger threshold analysis, maintain contemporaneous documentation distinguishing supply from non-supply (reimbursements, deposits, loans, etc.).

• For clients facing cancellation under s. 29(2) — pursue revocation under s. 30 within the 30-day (extendable to 90-day) window. Beyond the window, Suguna Cutpiece HC line and writ jurisdiction may permit restoration. Trigger B exposure is the consequence of revocation failure; revocation is the cheapest cure.

• Pursue voluntary registration before Department detection. Where a client realises retrospectively that registration was missed, voluntary registration with full tax + interest + late fee payment under s. 73(5) framework is the most effective mitigation. Significantly reduces s. 132 prosecution risk.

• Maintain registration-event documentation for the year of becoming liable. Date of crossing threshold; computation supporting the date; books / banking / invoices supporting the activity from that date. Foundation for s. 18(1)(a) ITC claim and s. 63 defence if it arises.

• Section 18(1)(a) ITC discipline — FORM GST ITC-01 within 30 days of becoming liable. For high-quantum claims (above Rs. 2 lakh), CA-certificate. The ITC offset is the principal substantive defence component in s. 63 cases.

• For multi-State operations — verify registration in every State where activity occurs. The PAN-level aggregate turnover under s. 2(6) is computed centrally but registration is State-wise. Missed-State registrations are common Trigger A defaults.

• Train tax / finance teams on threshold awareness and category compliance. Quarterly refresher on thresholds, Notification 10/2017-IT, s. 24 categories, banking-trail data. Pre-emptive compliance is the principal protection.

LITIGATION DEFENCE — DISPUTES UNDER SECTION 63

• Aggregate turnover recomputation. The substantive defence — verify s. 2(6) computation; exclude reimbursements under Rule 33, security deposits not applied as consideration, non-supply receipts (Schedule III), inter-State services within Notification 10/2017-IT, exempt supplies.

• Section 24 category — verify each claim. Inter-State, casual, RCM, ECO, ISD, TDS, OIDAR each have specific definitions. Where the Department's category claim is fact-incorrect, the compulsory-registration trigger fails.

• Notification 10/2017-IT carve-out for service providers. Rs. 20 lakh aggregate-turnover threshold for inter-State service supply (notwithstanding the s. 24(i) general rule). Standard defence for sub-threshold service providers.

• Date of becoming liable — pinpoint analysis. Tax liability arises only from the date of crossing threshold (Trigger A) or post-cancellation (Trigger B). Department's quantum often covers periods before liability; reduce to the actual liable period.

• Section 18(1)(a) ITC offset. For Trigger A defaulters who obtain registration retrospectively or proximately, ITC on inputs in stock at date of becoming liable is available. FORM GST ITC-01 with CA-certificate. Significant offset against gross tax exposure.

• Mandatory hearing under proviso — non-compliance is jurisdictional. ASMT-15 without recorded hearing is reviewable in s. 107 appeal or HC writ. Personal hearing record (or evidence of denial) is the primary procedural defence document.

• ASMT-14 specificity. Bald notices without specifics on trigger / period / quantum / material are reviewable. Particulars-seeking response or HC writ.

• Best-judgement quantum challenge. Same standard as s. 62 — reasoned estimate based on relevant material; bald multipliers or unexplained quantums reviewable. Pre-GST jurisprudence on best-judgement applies.

• 5-year limitation. Where ASMT-15 is issued beyond the s. 63 outer limit (5 years from s. 44 due date) and no valid extension applies, jurisdictionally defective.

• Section 168A force-majeure extensions. Notifications 9/2023-CT and 56/2023-CT extending limitation — constitutional validity contested; preserve grounds where the operative outer limit depends on these extensions.

• Trigger B revocation route. For post-cancellation continued-activity cases, pursue s. 30 revocation in parallel; Suguna Cutpiece HC line supports restoration on cure of defaults. Successful revocation converts Trigger B exposure to s. 62 framework.

• Section 132(1)(xi) prosecution defence. Coordinated civil + criminal counsel; voluntary registration / disclosure as mitigation; anticipatory bail; compounding under s. 138.
