Apportionment of tax and settlement of funds

Section 17 — Apportionment of tax and settlement of funds

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

BLOCK 3 — COMMENTARY

1. Statutory Architecture

2. Historical Context

Section 17 IGST operationalises Article 269A(1) of the Constitution — apportionment of IGST between Union and States. Pre-GST, inter-State commerce bore CST collected and retained by the originating State. The Constitutional shift under GST is destination-based allocation — the State where the supply is consumed (POS) takes the State share, not the originating State.

Sub-section (1) lists six categories where IGST is apportioned to the Central Government — primarily situations where the recipient cannot avail ITC or is outside the normal credit chain (unregistered, composition, ineligible, expired ITC, imports by unregistered). The apportionment is at the rate equivalent to CGST on similar intra-State supply. Sub-section (2) provides for the balance to be apportioned to the destination State (or Central Government for UTs without Legislature). The two provisos handle (a) cases where POS cannot be separately determined (proportionate to total supplies in FY), and (b) cases where taxable person is not identifiable (proportionate to State / UT collections in preceding FY).

Sub-section (2A) was inserted by IGST Amendment Act 2018 w.e.f. 01.02.2019. It permits ad hoc 50:50 apportionment of un-apportioned balances on Council recommendation, subsequently adjusted against sub-ss. (1) and (2) actual apportionment. This addressed the practical challenge of monthly settlement of IGST collections that could not yet be definitively apportioned due to data limitations.

Sub-section (4) is the transfer-out mechanism — once apportioned, the Central Government physically transfers the State share to State tax accounts. The Central share goes to central tax account / UTGST account. The mechanism operates through monthly settlement cycles based on CBIC Settlement Procedure.

Sub-section (5) is the refund-adjustment mechanism — if an IGST amount apportioned to a State is subsequently refunded to the taxpayer, the future apportionment to that State is reduced. This ensures the State doesn't retain a benefit from amounts subsequently refunded.

The interaction with s. 49(5) CGST utilisation order is critical. Under s. 49(5), IGST credit in the electronic credit ledger is utilised first for IGST liability, then CGST, then SGST. When IGST credit is utilised for CGST / SGST liability, sub-s. 4 IGST + s. 18 IGST trigger transfer of equivalent amount from IGST account to CGST / SGST accounts. The cross-credit fungibility under GST is operationally enabled by this transfer architecture.

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.

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.

Mafatlal Industries Ltd v Union of India — (1997) 5 SCC 536 [Supreme Court — 9-Judge Constitution Bench]

Brief Facts: Multiple manufacturers had paid central excise duty under protest, succeeded in challenges, and sought refund. The question arose whether the doctrine of unjust enrichment applies to indirect-tax refunds, whether refund can be denied if the burden has been passed on, and whether common-law refund claims survive the statutory refund regime.

Issue: Constitutional and doctrinal scope of refund of indirect taxes — whether unjust enrichment bars refund where burden has been passed on; whether the statutory refund mechanism is exclusive.

HELD: Constitution Bench held (i) the statutory refund mechanism under the Central Excise Act is exclusive — common-law refund claims are excluded; (ii) the doctrine of unjust enrichment applies — refund will not be granted where the assessee has passed on the burden to the ultimate consumer; (iii) the burden of proof on incidence-passing is on the claimant.

"Where the duty has been passed on to the buyer, the manufacturer is not entitled to refund. To do otherwise would be to enrich the manufacturer at the expense of the consumer — a course no principle of justice can support."

Relevance: Foundational unjust-enrichment authority that animates s. 54(8)(e) and the Consumer Welfare Fund mechanism. Decisive in every IGST refund claim including zero-rated/inverted-duty/excess-balance refunds.

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.

Commissioner of Income Tax v Vatika Township Pvt Ltd — (2015) 1 SCC 1 [Supreme Court — 5-Judge Constitution Bench]

Brief Facts: The Income-tax Act's surcharge provisions had been amended mid-year. Question was whether the amendment applied retrospectively to assessment years already commenced. Constitution Bench was constituted to settle conflicting two-Judge Bench rulings on the presumption of prospectivity for fiscal statutes.

Issue: Whether a fiscal statute that imposes or enhances a burden operates prospectively unless expressly or by necessary implication retrospective; and what is the standard of clarity required for retrospective imposition.

HELD: Strong presumption of prospectivity for any provision that imposes or enhances a burden. Retrospective imposition requires either an express statutory direction or a necessary implication so unmistakable that no reasonable construction can avoid it. Beneficial provisions may be construed retrospectively; burden-imposing provisions cannot.

"If a legislation confers a benefit on some persons but without inflicting a corresponding detriment on another, it could be construed to be retrospective. The same is not true of a provision imposing a tax or otherwise creating a fresh burden — there, the presumption of prospectivity is at its strongest."

Relevance: Constitutional anchor for prospective operation of GST amendments. Decisive in every dispute over the effective date of a notification, amendment, or rule change under IGST.

5. Worked Examples

6. Practitioner Planning

• For practitioners, s. 17 is largely back-end; understanding helps explain to clients why their inter-State supplies feed into destination-State revenues.
• For clients in tax-policy / Government advisory roles, sub-s. (2A) ad hoc 50:50 framework is critical for revenue forecasting.
• For ITC planning, recognise that delayed ITC availability beyond s. 16(4) window triggers sub-s. (1)(c) apportionment to Centre — affects national-State balance.
• For inter-State branch supplies (Schedule I deemed supplies), IGST flows through apportionment to destination State branch.
• For export-refunds, recognise sub-s. (5) adjustment mechanism — State that received apportionment bears refund impact in subsequent cycles.
• For SEZ supplies under s. 7(5)(b), apportionment to SEZ-host State subject to LUT / IGST-paid / Notif 18 election.
• For IGST-on-imports, apportionment under sub-s. (1)(d)/(e)/(f) for unregistered / non-ITC recipients; sub-s. (2) for ITC-availing recipients to importer-State.
• For audit assignments to revenue ministries, sub-s. (2A) ad hoc apportionment data is operative input.
• For Centre-State coordination matters, s. 17 architecture provides the framework.
• For composition taxpayers under s. 10 CGST, sub-s. (1)(a)/(d) apportionment automatic — composition taxpayers don't get ITC.
• Periodic review of GST Council recommendations on ad hoc apportionment rates / formulae.
• Monitor State Finance Ministry settlement reports for client State-revenue impact.
• For multi-State enterprises, recognise that intra-firm supplies feed apportionment to destination-State branches.
• Maintain awareness of CBIC Settlement Procedure updates.
• For tax-policy advocacy, s. 17 architecture is the framework for federal revenue distribution.

7. Litigation Defence

• Apportionment is largely Centre-State internal — not direct taxpayer litigation. Defences focus on upstream POS, supply classification, and ITC eligibility.
• Mohit Minerals defence — for Council-recommendation-based apportionment changes, persuasive not binding nature.
• AIFTP constitutional anchor — Article 269A(1) framework for apportionment.
• Bharti Airtel finality defence — for any retrospective apportionment-recalculation affecting taxpayer entitlements.
• Mafatlal unjust enrichment — for refund disputes that interact with sub-s. (5) adjustment.
• VKC Footsteps statutory-entitlement defence — for refund-related apportionment disputes.
• Vatika Township prospectivity — for Amendment Act 2018 sub-s. (2A) insertion, prospective from 01.02.2019.
• Maneka Gandhi audi alteram partem — for taxpayer-affecting apportionment-recalculation without hearing.
• Filco Trade Article 142 — for systemic settlement architecture failures affecting taxpayer rights.
• Hierarchy-of-instruments defence — CBIC Settlement Procedure cannot enlarge s. 17 statutory framework.
• Sub-s. (4) transfer-out timeline defence — prescribed timelines must be honoured; delays may attract administrative remedies.
• Sub-s. (5) refund-adjustment defence — taxpayer refund cannot be denied based on State-Centre settlement complexity.
• Pre-Amendment Act 2018 defence — pre-01.02.2019 settlements not subject to sub-s. (2A) ad hoc framework.
• Inter-governmental dispute resolution — apportionment disputes between Centre and States are resolved through GST Council mechanism, not litigation.
• Council-recommendation binding-character defence — for ad hoc rates under sub-s. (2A), Mohit Minerals persuasive-not-binding doctrine.
• Constitutional Article 269A(1) anchor — fundamental architectural anchor for apportionment.
