Application of provisions of Central Goods and Services Tax Act

Section 20 — Application of provisions of Central Goods and Services Tax Act

BLOCK 2 — PRE-GST COUNTERPART / PARALLEL PROVISIONS / OPERATIVE RULES

BLOCK 3 — COMMENTARY

1. Statutory Architecture

2. Historical Context

Section 20 IGST is the structural keystone that prevents the IGST Act from being a massive duplicate of the CGST Act. Instead of separately codifying twenty-five operative areas — scope of supply, time/value, ITC, registration, invoicing, accounts, returns, payment, TDS, TCS, assessment, refunds, audit, inspection, demands, advance ruling, appeals, offences, job work, e-commerce, transitional, etc. — the IGST Act applies the CGST Act provisions mutatis mutandis through s. 20.

The 25-item list covers virtually every operative aspect of GST administration. Items (i) to (iii) cover the substantive framework (supply / composite-mixed / time-value). Items (iv) to (xi) cover taxpayer compliance (ITC / registration / invoicing / accounts / returns / payment / TDS / TCS). Items (xii) to (xvi) cover enforcement (assessment / refunds / audit / inspection-search / demands-recovery). Items (xvii) to (xix) cover liability and review (succession / advance ruling / appeals). Items (xx) to (xxv) cover ancillary frameworks (presumption / offences / job work / e-commerce / transitional / miscellaneous + interest/penalty).

The 'mutatis mutandis' clause is critical — provisions apply with necessary modifications. Where the CGST provision references 'central tax', it is read as 'integrated tax' under IGST. Where it references 'CGST Act', it is read as 'IGST Act'. Where it references 'central tax officer', it includes State / UT tax officers cross-empowered under s. 4 IGST.

The five provisos modify specific CGST provisions when applied to IGST:

Proviso 1: TDS at 2% under s. 51 CGST — same rate as CGST + SGST combined (1% + 1%). Maintains rate parity for cross-tax-head consistency.

Proviso 2: TCS at up to 2% under s. 52 CGST — Council recommended rate. Originally 1% (matching CGST + SGST 0.5% + 0.5%); reduced to 0.5% (combined 1%) by Notification 15/2024 effective 10.07.2024.

Proviso 3: Value includes other taxes / duties / cesses / fees charged separately, except IGST and GST Compensation Cess. Prevents double-taxation by excluding GST chain from value base.

Proviso 4: Sum-total penalty — IGST penalty = CGST + SGST penalties for same offence. Avoids cumulative penalty stacking when same offence is penalised under multiple regimes.

Proviso 5 (inserted FA 2018 w.e.f. 01.02.2019): Appeal monetary limits — Appellate Authority Rs. 50 crore maximum and Tribunal Rs. 100 crore maximum. These are statutory ceilings on amounts payable as pre-deposit / appellate stage. Critical for high-value IGST disputes — ensures pre-deposit doesn't become prohibitive.

Operationally, s. 20 means practitioners reading the IGST Act must always cross-reference to the CGST Act for any operational mechanism. The single-section nature of s. 20 belies its enormous practical importance — virtually every IGST compliance task implicates the CGST Act through s. 20.

The exclusion of 'late fee' from item (viii) is notable. Late fee for returns is governed separately under s. 47 CGST + IGST-specific notification; not automatically applied through s. 20. This avoids late-fee multiplication when same return delay attracts CGST + IGST + SGST late fees.

3. Judicial Evolution

Union of India v Mohit Minerals Pvt Ltd — (2022) 10 SCC 700 [Supreme Court — 3-Judge Bench (Constitution Bench questions)]

Brief Facts: Importers of coal on CIF basis were held liable under Notification Nos. 8/2017-Integrated Tax (Rate) and 10/2017-Integrated Tax (Rate) to pay IGST on ocean freight component under reverse charge under s. 5(3)/(4) of the IGST Act. Importers challenged the levy as ultra vires the charging section and contended that IGST had already been paid on CIF value (which included freight) at the time of import under s. 3(7) of the Customs Tariff Act.

Issue: Whether IGST could be levied separately on the ocean freight component of CIF imports when the entire CIF value (inclusive of freight) had suffered IGST under s. 3(7) of the Customs Tariff Act; and whether GST Council recommendations are binding on the Union and States.

HELD: Levy struck down. The Court held that the impugned notification offended the principle of 'composite supply' under s. 8 of the CGST Act because ocean freight in CIF imports is part of the composite supply of imported goods and cannot be artificially severed. Further, the GST Council's recommendations are recommendatory, not binding, on the Union and States — both Parliament and State legislatures have simultaneous legislative power under Article 246A.

"The recommendations of the GST Council are not binding on the Union and the States. The recommendations only have a persuasive value. To regard them as binding would disrupt fiscal federalism, where both the Union and the States are conferred equal power to legislate on GST."

Relevance: Foundational authority on the IGST charging section, the limits of reverse-charge notifications under s. 5(3)/(4), and the constitutional architecture of the GST Council. Repeatedly cited in RCM, place-of-supply, and composite-supply disputes.

Union of India v Bharti Airtel Ltd — (2022) 4 SCC 328 [Supreme Court — 2-Judge Bench]

Brief Facts: Bharti Airtel claimed it had under-reported ITC in GSTR-3B for July-Sept 2017 (the early GST months when GSTR-2A was not operational) and sought rectification of GSTR-3B for those months to correct the under-claim. Delhi HC permitted rectification; Revenue appealed to SC.

Issue: Whether GSTR-3B for past periods can be rectified to correct an under-claim of ITC where the registered person's books would support the correction but GSTN does not allow retrospective edit.

HELD: Rectification not permitted. The Court held that the GST return-filing regime is self-assessed; the registered person is duty-bound to verify entitlements at the time of filing and cannot, after the fact, claim that GSTR-2A was not available. ITC is a statutory entitlement that must be claimed within the period prescribed under s. 16(4) and not through retrospective rectification.

"GST is a self-assessment regime. The registered person bears the burden of correctly computing and reporting tax liability at the time of filing the return. The unavailability of GSTR-2A does not absolve the assessee of this duty."

Relevance: Substance-over-form authority on self-assessment, the finality of GSTR-3B, and limits on retrospective rectification — critical for place-of-supply disputes where mis-classification may be alleged years later.

Union of India v VKC Footsteps India Pvt Ltd — (2022) 2 SCC 603 [Supreme Court — 2-Judge Bench]

Brief Facts: Manufacturer-exporters with inverted duty structure (input GST > output GST) sought refund of accumulated input tax credit under s. 54(3) read with Rule 89(5) of the CGST Rules. Rule 89(5) permitted refund of unutilised ITC only on 'inputs' (goods), excluding 'input services'. Gujarat HC struck down the exclusion; Madras HC upheld it. SC heard the conflict.

Issue: Whether Rule 89(5) of the CGST Rules — by restricting inverted-duty refund to inputs (goods) and excluding input services — is ultra vires s. 54(3) of the CGST Act.

HELD: Rule 89(5) upheld. The Court held that s. 54(3) is enabling, not mandatory, and the legislative policy choice to confine inverted-duty refund to inputs (goods) is constitutionally permissible. The refund of unutilised ITC is not a constitutional right; it is a statutory concession that the legislature can shape and limit. The Court urged the GST Council to revisit the formula but did not strike down the rule.

"Refund of unutilised ITC is a statutory entitlement, not a constitutional right. The legislature in its wisdom may choose to grant the entitlement with such conditions and limitations as it thinks fit. We cannot rewrite the formula by judicial fiat."

Relevance: Definitive authority on inverted-duty refund mechanics, the policy/discretion distinction in refund jurisprudence, and the standard of review for delegated legislation under GST.

Chief Commissioner of Central Goods and Service Tax v Safari Retreats Pvt Ltd — (2024) SCC OnLine SC 2966 [Supreme Court — 2-Judge Bench]

Brief Facts: Safari Retreats constructed a shopping mall and leased it out — output supply was taxable rental. It sought ITC on construction goods/services (cement, steel, works contract). Revenue invoked s. 17(5)(d) of the CGST Act to deny ITC on inputs/input services used in construction of immovable property other than plant or machinery 'on his own account'. Orissa HC read down s. 17(5)(d) for leasing-out cases; SC heard the appeal.

Issue: Whether s. 17(5)(d) bars ITC on construction inputs/services where the immovable property constructed is itself used to make taxable outward supplies (here, rental); and what is the scope of the 'plant or machinery' exclusion.

HELD: ITC permitted in a 'functionality test' framework. The Court held that whether a building qualifies as 'plant' within the 'plant or machinery' exclusion is a fact-specific functional inquiry — if the building itself is the means by which the registered person makes outward taxable supplies (e.g., a hotel, a mall, a warehouse), it can qualify as plant and ITC on its construction is admissible. Matter remitted for application of functionality test.

"Whether a particular building qualifies as a plant within the meaning of the expression 'plant or machinery' is a question of fact that has to be determined keeping in mind the business of the registered person and the role that building plays in that business."

Relevance: Critical reset on ITC architecture for real-estate / leasing / hospitality. Important for IGST place-of-supply (immovable property) disputes where ITC architecture interacts with location-of-supply rules under s. 12(3) of the IGST Act.

All India Federation of Tax Practitioners v Union of India — (2007) 7 SCC 527 [Supreme Court — 3-Judge Bench]

Brief Facts: The constitutional validity of the service-tax levy on chartered accountants, cost accountants, and architects was challenged on the ground that these professions had been historically regulated by State legislation and were therefore outside Union legislative competence.

Issue: Constitutional foundation of the service-tax levy — whether 'service' can be taxed by the Union under the residuary entry (Entry 97 List I) and what is the doctrinal nature of a service-tax levy.

HELD: Service-tax upheld. The Court held that service-tax is a value-added tax on the value of services rendered, traceable to Entry 97 of List I until Entry 92C was inserted by the Constitution (88th Amendment). The economic concept of value addition through services is the doctrinal basis on which service-tax — and now GST on services — rests.

"Service-tax is a value-added tax on the commercial activity of providing services. The taxable event is the rendition of service and the levy attaches to the value addition at the point of service delivery."

Relevance: Constitutional anchor for taxation of services under GST — pre-101st-Amendment doctrinal framework that informs the place-of-supply concept under s. 12 and s. 13 of the IGST Act.

Skill Lotto Solutions Pvt Ltd v Union of India — (2021) 15 SCC 667 [Supreme Court — 3-Judge Bench]

Brief Facts: Petitioner, a distributor of lottery tickets, challenged the levy of GST on lottery on the ground that lottery is an 'actionable claim' which is not 'goods' for GST purposes (the actionable-claim exclusion in Schedule III) and therefore the constitutional power to tax goods is missing.

Issue: Whether lottery is 'goods' under the CGST/IGST Acts; whether the inclusion of lottery as a taxable actionable claim is constitutional; and whether the valuation under s. 15 (face value of lottery ticket) is permissible.

HELD: Levy upheld. The Court held that the definition of 'goods' under s. 2(52) of the CGST Act is wide enough to include actionable claims, and the inclusion of lottery within taxable actionable claims is a legislative policy choice within Parliament's competence. Valuation at face value is not arbitrary because the prize component is a contingent payout, not a deduction.

"The definition of 'goods' in the CGST Act, by including actionable claims, is a deliberate expansion of the historical concept and is constitutionally permissible. Lottery, being one of the three specified actionable claims rendered taxable, is liable to GST at face value."

Relevance: Constitutional anchor for the breadth of 'goods' under GST and for the legislative discretion in designing valuation rules. Foundational for actionable-claim/derivative-instrument supply disputes.

4. Circulars and Notifications

IGST (Amendment) Act 2018, s. 8 dated 29.08.2018 (effective 01.02.2019) — Insertion of proviso 5 — appeal monetary limits

Inserted proviso 5 to s. 20 — appeal monetary limits at Appellate Authority Rs. 50 crore and Appellate Tribunal Rs. 100 crore.
