10. PRACTITIONER QUICK-REFERENCE — COMPLIANCE + STRATEGIC POSTURE
• For every input, verify five-fold conditions under Sec 16(2) — invoice, supplier-reporting, receipt, non-restriction, tax-paid, return-filed.
• Track GSTR-2B monthly — sub-s. (2)(aa) and (ba) interface — supplier's GSTR-1 default cascades to recipient's ITC denial.
• 180-day supplier-payment proviso — for B2B operations, track payment cycle; failure triggers ITC reversal + interest + re-availment framework.
• 30-November outer limit (FA 2022) — for FY 2024-25, claim ITC by 30-Nov-2025 or annual return date, whichever earlier.
• Section 17(5) ten blocked-credit categories — strict construction (Dilip Kumar) — for construction-inputs (sub-s. (5)(d)), Safari Retreats + FA 2024 framework.
• Section 17 apportionment — Rule 42 (inputs/services) + Rule 43 (capital goods 60 months) — for businesses with mixed taxable/exempt supplies.
• For supplier defaults, bona-fide-recipient framework (Suncraft Energy / D.Y. Beathel HC line) — substantive payment + receipt evidence anchors defence.
• For M&A transactions, Section 18(3) + ITC-02 framework — coordinate with section 22(3)/(4) successor registration.
• For multi-State entities — Section 20 mandatory ISD effective 1-Apr-2025 — restructure central-services flow to ISD framework + GSTR-6 + State GSTRs.
• Section 19 job-work — 1-year inputs / 3-year capital goods deeming windows — track diligently; moulds/dies carve-out under sub-s. (7).

13. KEY TAKEAWAYS — CHAPTER OVERVIEW
13. KEY TAKEAWAYS — CHAPTER OVERVIEW
• Chapter V is the lifeblood of GST architecture — ITC eliminates cascading taxation. Mastery of Sec 16 conditions + Sec 17 framework is non-negotiable.
• FA 2022 substantially restructured the framework — Sec 16(2)(aa), (ba) + Sec 38 GSTR-2B/IMS + Sec 41 self-assessed + Sec 16(4) 30-November outer limit.
• Section 17(5) ten blocked-credit categories — strict construction (Dilip Kumar) — particularly Sec 17(5)(d) construction-inputs post-Safari Retreats + FA 2024 retrospective.
• Bharti Airtel substance-over-form framework — substantive accuracy in books governs; portal records support. Foundational for ITC defence.
• Bona-fide-recipient framework (Suncraft Energy / D.Y. Beathel HC line) — for supplier defaults, substantive payment + receipt + due diligence anchors recipient's defence.
• Section 20 mandatory ISD (FA 2024) effective 1-Apr-2025 — significant operational restructuring for multi-State entities. Section 24(viii) compulsory registration.
• Section 18 special-circumstance ITC + Section 19 job-work framework + Section 21 ISD recovery — coordinated transitional + operational + recovery framework.
• Section 50 interest framework — 18% standard / 24% on wrongly availed AND utilised. FA 2021 retrospective net-cash-liability framework substantially relieves pre-2021 disputes.
• Rule 86B 99% cap framework + Rule 88B interest computation + Rule 37A supplier-default reversal — comprehensive operational discipline.
• Practitioner's ITC compliance is foundational — every input requires comprehensive analysis. For Departmental defence, comprehensive documentary trail + substance-over-form discipline.
