This Part operates independently. It addresses the GST consequences arising after inventory loss events — specifically ITC reversal under Section 17(5)(h), subsequent scrap disposal, and capital goods exit under Section 18(6).
Foundational Legal Doctrine — The GST Separation Principle
Under the CGST Act, the tax consequences of inventory loss events are governed by a strict three-layer legal separation framework:
- Commercial layer → settlement / insurance / recovery
- Accounting layer → write-off / impairment / destruction entry
- Tax layer (GST) → ITC reversal or outward supply taxation
Core Legal Proposition
GST consequences are triggered only by the juridical status of goods, not by financial recovery or commercial settlement.
Accordingly:
- ITC reversal and settlement receipt are non-causal events
- One does not legally trigger, negate, or modify the other
Section 17(5)(h) — ITC Blockage: Statutory Trigger Doctrine
Under Section 17(5)(h), ITC is blocked where goods are:
- lost
- stolen
- destroyed
- written off in books of account
- disposed of as gifts or free samples
Interpretative Rule (Substantive Test)
The provision is triggered not by accounting narration, but by:
finality of goods exiting the taxable supply chain
Legally Determinative Question
For audit or litigation purposes:
“Has the goods ceased to exist as a usable taxable asset in the hands of the registered person through physical or accounting finality?”
Inventory Status Classification Matrix (Defence-Grade)
| Status of Goods | GST Consequence |
|---|---|
| Physically available + not written off | No ITC reversal permitted |
| Written off in books | Mandatory reversal under Section 17(5)(h) |
| Destroyed / condemned / obsolete disposal | Mandatory reversal |
| Free samples / gifts | Mandatory reversal |
Non-Trigger Principle (Critical Clarification)
A settlement or compensation entry is legally irrelevant for Section 17(5)(h).
- Settlement without write-off → no reversal
- Write-off without settlement → reversal mandatory
- Both co-existing → reversal governed only by write-off status
Scrap Sale .. Independent Supply Doctrine (Section 7 + Section 9)
Scrap disposal represents a fresh taxable event, independent of prior ITC determination.
Core Juridical Separation
Scrap sale is not a recovery mechanism.
It is a distinct supply transaction under GST law.
Therefore:
- ITC reversal logic remains untouched
- Scrap sale does not retroactively validate or invalidate ITC position
Tax Treatment Architecture
Scrap disposal requires:
- Tax invoice issuance under Section 31
- GST charged on transaction value under Section 9
- Reporting in GSTR-1 and GSTR-3B as outward supply
Critical Legal Boundary
| Event | Legal Character |
|---|---|
| Write-off / destruction | ITC reversal event |
| Scrap sale | Independent taxable supply |
These operate in mutually exclusive legal domains.
Capital Goods Exit — Section 18(6) Exclusive Charging Mechanism
Where assets qualify as capital goods, Section 18(6) overrides general inventory principles.
Statutory Computation Rule
Tax payable = higher of:
- ITC availed reduced by prescribed depreciation, OR
- GST on transaction value
Doctrinal Distinction
| Provision | Legal Nature | Application |
|---|---|---|
| Section 17(5)(h) | ITC blockage | Inventory loss / consumption doctrine |
| Section 18(6) | Exit taxation | Capital goods disposal doctrine |
These provisions are mutually exclusive and cannot be conflated.
Audit Risk Mapping — Litigation Hotspots
GST scrutiny in this area is typically driven by process failure rather than interpretative disputes.
| Risk Area | Trigger Point |
|---|---|
| Inventory mismatch | Physical stock vs books/ERP divergence |
| ITC retention | Write-off recorded but reversal not done |
| Scrap leakage | Disposal without GST invoice |
| Capital goods misclassification | Section 18(6) not applied correctly |
| Temporal misalignment | Write-off and GST reporting in different periods |
Judicial Reality Principle
GST disputes in this domain arise from evidentiary discontinuity, not legal ambiguity
Compliance Defence Architecture
A defensible GST position requires real-time classification discipline at the moment of inventory change.
Mandatory Classification Protocol
At the point of inventory event:
-
Determine status:
- active stock
- written off
- destroyed
- scrapped
-
Apply correct tax consequence immediately:
- Written off/destroyed → Section 17(5)(h) reversal in same tax period
- Scrapped → GST invoice and outward supply reporting
- Capital goods → Section 18(6) computation only
Evidentiary Integrity Requirements
Maintain contemporaneous audit-proof documentation:
- Authorised write-off approvals
- Scrap sale invoices and contracts
- Destruction certificates / third-party confirmations
- Inventory reconciliation statements
- ERP audit trail of status change
Core Legal Takeaways (Executive Litigation Summary)
- ITC reversal is triggered only by statutorily recognised inventory cessation events
- Settlement or compensation is legally irrelevant for Section 17(5)(h)
- Scrap sale is a fresh taxable supply, not an adjustment mechanism
- Capital goods disposal is governed exclusively by Section 18(6)
- Audit sustainability depends on temporal alignment of inventory status and GST reporting
Closing Principle — GST Juridical Finality Doctrine
GST operates on a foundational rule:
Tax liability attaches to the legal status of goods at the moment of classification — not the financial outcome thereafter.
Accordingly, the strongest defence is not post-facto justification, but:
- contemporaneous classification
- consistent accounting alignment
- and synchronized GST reporting discipline
