Worked examples — five live scenarios

Example 1 — Supply before, both invoice + payment after

Facts: Rate change from 18% to 12% effective 1-Oct-2025. Goods delivered 25-Sep-2025. Invoice 5-Oct. Payment 10-Oct.

Analysis: Clause (a) supply before. Sub-clause (i) — both invoice + payment after. Earlier of invoice (5-Oct) or payment (10-Oct) — 5-Oct. Time of supply = 5-Oct-2025. Post-change rate 12% applies.

Result: Despite pre-change supply, post-change time-of-supply triggers new rate.

Example 2 — Supply before, invoice before, payment after

Facts: Same rate change. Delivery 25-Sep, invoice 28-Sep, payment 5-Oct.

Analysis: Clause (a)(ii) — invoice before change. Time of supply = invoice date 28-Sep. Pre-change rate 18% applies.

Result: Pre-change rate preserved by pre-change invoicing.

Example 3 — Supply after, invoice + payment before

Facts: Same rate change. Delivery 10-Oct, invoice 25-Sep, payment 28-Sep.

Analysis: Clause (b)(ii) — supply after, but invoice + payment before. Earlier of invoice / payment — 25-Sep. Time of supply = 25-Sep. Pre-change rate 18% applies.

Result: Advance invoicing + payment locks pre-change rate even though supply is post-change.

Example 4 — 4-working-day proviso

Facts: Rate change 1-Oct-2025. Books entry of payment 28-Sep. Bank credit 8-Oct (more than 4 working days after 1-Oct).

Analysis: Proviso applies. Bank credit (8-Oct) governs, not books entry (28-Sep). Payment date = 8-Oct. Time-of-supply analysis shifts. Pre-change rate cannot be invoked via books-entry arbitrage.

Result: 4-working-day proviso prevents arbitrage.

Example 5 — Real-estate rate restructuring

Facts: Real-estate rate change 1-Apr-2019. Under-construction flat — agreement 15-Mar, advance 20-Mar, possession 30-Jun.

Analysis: Construction services have specific framework. For pre-change advance: time-of-supply on payment 20-Mar. Pre-change rate applies to advance. Post-change construction services subject to new rate. Practitioner discipline — coordinate with construction-services specific framework + s. 14.

Result: Sectoral rate-change with s. 14 transitional discipline.

Planning and litigation strategy

• For known rate-change events, plan invoice + payment timing.
• For rate-reduction, consider deferring invoice / payment to post-change.
• For rate-increase, consider accelerating to pre-change.
• Maintain documentary trail of all dates.
• Coordinate with Council deliberations for upcoming rate-changes.
• Apply Vatika prospective-operation framework.
• Respect 4-working-day proviso for bank-credit discipline.
• For multi-State operations, coordinate parallel SGST rate-changes.
• Build precedent file on rate-change jurisprudence.
• Train compliance teams on s. 14 framework.
• Coordinate with s. 12 / 13 general framework for non-rate-change supplies.
• Apply Bharti Airtel substance-over-form discipline.
• For sectoral rate-changes, coordinate with sector-specific framework.
• Maintain readiness for rate-change transition planning.
• Coordinate with broader pricing / contracting strategy.

Litigation defence

• For rate-change disputes, build comprehensive documentary trail.
• Apply six-scenario matrix rigorously.
• Plead 4-working-day proviso defensively.
• Use Vatika prospective-operation framework.
• Plead Mohit Minerals constitutional framework for rate-change Notification validity.
• Use Mafatlal procedural-fairness framework.
• Apply Bharti Airtel substance-over-form discipline.
• Use Whirlpool framework for writ jurisdiction.
• Apply Calcutta Discount Co. for jurisdictional discipline.
• Plead Modern Dental proportionality for any rate-change challenge.
• Build precedent file on rate-change jurisprudence.
• Coordinate with State / UTGST parallel rate-change framework.
• Maintain readiness for rate-change litigation.
• Use Maneka Gandhi procedural-fairness for natural-justice anchor.
