Worked examples — five live scenarios

Example 1 — Mixed taxable / exempt apportionment

Facts: Hospital supplies (a) exempt healthcare services Rs. 6 crore; (b) taxable non-healthcare services (e.g., pharmacy retail) Rs. 4 crore. Total Rs. 10 crore. Common inputs ITC Rs. 1 lakh.

Analysis: Sub-s. (2) — Rule 42. Common ITC reversal = Rs. 1 lakh × (Rs. 6 crore / Rs. 10 crore) = Rs. 60,000. Net ITC = Rs. 40,000.

Result: Rule 42 apportionment operative.

Example 2 — Motor vehicle blocked

Facts: Taxpayer buys car (5-seater) for office use. GST paid Rs. 1.8 lakh.

Analysis: Sub-s. (5)(a) — motor vehicle for passenger transport (≤13 seats). ITC blocked. Exceptions (further supply, passenger transport, driving school) don't apply.

Result: ITC blocked. Cost to taxpayer.

Example 3 — Construction-input under Safari Retreats

Facts: Commercial-property developer built office building, claimed ITC on construction-inputs pre-October 2024.

Analysis: Sub-s. (5)(d) bar — Safari Retreats SC + FA 2024 retrospective amendment. Pre-amendment liberal claim challenged. Section 11A monitoring for general-practice regularisation.

Result: Safari Retreats framework operative. Pre-amendment claim subject to s. 11A regularisation possibility.

Example 4 — Banks 50% option

Facts: Bank's total ITC for month Rs. 10 lakh. Bank exercised sub-s. (4) 50% option.

Analysis: 50% × Rs. 10 lakh = Rs. 5 lakh ITC claimed. Rs. 5 lakh lapses. Operational simplification.

Result: 50% option operates. Lapse is the cost.

Example 5 — CSR expenditure

Facts: Company spent on CSR activities under s. 135 Companies Act. Inputs received with GST.

Analysis: FA 2023 — sub-s. (5)(g) inserted, ITC blocked on CSR-related inputs. Practitioner discipline — track FA 2023 effective date.

Result: CSR ITC blocked post-FA 2023.

Planning and litigation strategy

• Build comprehensive s. 17 analysis SOPs for every input.
• For mixed taxable / exempt operations, build Rule 42 / 43 computation framework.
• Track Safari Retreats + FA 2024 + s. 11A framework for construction-input matters.
• For banks / NBFC, evaluate sub-s. (4) option annually.
• For blocked categories, verify exceptions before claiming.
• For capital goods, build 60-month Rule 43 tracking.
• Apply Dilip Kumar discipline defensively where claim is clear.
• Maintain documentary trail of usage / apportionment analysis.
• Coordinate with Income-tax depreciation framework.
• Apply Bharti Airtel substance-over-form discipline.
• Track FA amendments to sub-s. (5) categories.
• Build precedent file on s. 17 jurisprudence.
• For sectoral matters, track sector-specific AAR / AAAR rulings.
• Coordinate with State / UTGST parallel framework.
• Apply Vatika prospective-operation for amendments.

Litigation defence

• For s. 17 ITC denials, build sub-section-specific defence.
• For construction-input matters, plead Safari Retreats + s. 11A framework.
• For Rule 42 / 43 disputes, plead VKC Footsteps legislative-framework discretion.
• Apply Bharti Airtel substance-over-form discipline.
• Plead Mohit Minerals constitutional framework.
• Use Mafatlal procedural-fairness framework.
• Apply Vatika prospective-operation for amendments.
• Use Whirlpool framework for writ jurisdiction.
• Apply Calcutta Discount Co. for jurisdictional discipline.
• Plead Modern Dental proportionality.
• Use Dilip Kumar strict-construction discipline defensively.
• For exception-applicability, build factual matrix.
• Build precedent file on s. 17 jurisprudence.
• Maintain readiness for s. 17 litigation.
• Coordinate with State / UTGST parallel framework.
• Use Maneka Gandhi procedural-fairness for natural-justice anchor.
