Worked examples — five live scenarios

Example 1 — Multi-State entity central audit-fee

Facts: Multi-State entity with GSTINs in Delhi, Maharashtra, Karnataka. Central audit fee Rs. 10 lakh + IGST Rs. 1.8 lakh received at HO (Delhi). Turnover: Delhi Rs. 50 cr, Maharashtra Rs. 30 cr, Karnataka Rs. 20 cr.

Analysis: Post-1-Apr-2025, HO registers as ISD. ISD distributes Rs. 1.8 lakh per Rule 39 — Delhi 50%, Maharashtra 30%, Karnataka 20%. ISD invoices issued. GSTR-6 filed. Each recipient claims its share.

Result: Mandatory ISD framework operative.

Example 2 — Pre-amendment optional ISD vs cross-charge

Facts: Same entity, pre-1-Apr-2025. HO received audit fee. Used cross-charge — issued tax invoice to Maharashtra / Karnataka for their share.

Analysis: Pre-amendment framework — cross-charge alternative valid per Circular 199/11/2023-GST + Columbia Asia framework. Audit may apply pre-amendment framework. Post-1-Apr-2025, mandatory ISD transition required.

Result: Pre-amendment cross-charge defensible. Transition planning critical.

Example 3 — Attribution discipline

Facts: Marketing service received at HO. Service specifically for North-Indian markets (Delhi + UP + Punjab). Other States not benefiting.

Analysis: Sub-s. (3) — distribution only to attributable recipients. Pro-rata among Delhi, UP, Punjab only (not all States). Documentary trail of attribution.

Result: Attribution discipline. Selective distribution.

Example 4 — Credit-type conversion

Facts: ISD received CGST Rs. 1 lakh + SGST Rs. 1 lakh from intra-State input service. Distribution to inter-State distinct persons.

Analysis: Sub-s. (2) — CGST may be distributed as IGST for inter-State recipients. SGST distribution discipline parallel (State-specific). Conversion ensures inter-State framework respected.

Result: Credit-type conversion operative.

Example 5 — Operational restructure for FA 2024

Facts: Pre-FA 2024 multi-State entity used cross-charge. Plans transition by 1-Apr-2025.

Analysis: Transition planning — register HO as ISD; identify input-services for centralised receipt; build Rule 39 distribution mechanism; coordinate GSTR-6 + State GSTRs. Operational restructure timeline.

Result: FA 2024 transition framework. Comprehensive restructure required.

Planning and litigation strategy

  • • For multi-State entities, transition to mandatory ISD by 1-Apr-2025.
  • • Build ISD registration + GSTR-6 compliance framework.
  • • Identify central-office input services for ISD distribution.
  • • Build Rule 39 pro-rata distribution methodology.
  • • Maintain attribution analysis for each input service.
  • • Coordinate with State GSTIN compliance.

  • • Plead Modern Dental proportionality.
  • • For attribution challenges, build factual documentary trail.
  • • For pro-rata computation challenges, plead Rule 39 specificity.
  • • Build precedent file on ISD jurisprudence.
  • • Maintain readiness for ISD litigation.
  • • Coordinate with State / UTGST parallel framework.
  • • Use Maneka Gandhi procedural-fairness for natural-justice anchor.
