Input Tax Credit (ITC) is one of the core pillars of the GST regime, ensuring seamless credit flow and avoiding cascading of taxes. However, ITC is not an absolute right.
In the world of GST, Input Tax Credit (ITC) is generally a “use it or lose it” system. The fundamental principle is that ITC is available only on goods or services used for making taxable outward supplies. When goods are lost, destroyed, or given away for free, that chain is broken, and the law requires you to reverse the credit.
Under Section 17(5)(h) of the CGST Act, 2017, ITC must be reversed in specific scenarios involving the disposal of goods.
Understanding when ITC reversal is required is crucial for compliance and avoiding litigation. Certain situations require reversal of ITC, especially in cases involving manufacturing losses, spoilage, and free samples.
Legal Framework for ITC Reversal
Under GST law, ITC eligibility is governed by Section 16, while restrictions are provided under Section 17.
As per GST provisions:
- ITC is available only when inputs are used in the course or furtherance of business
- Certain credits are blocked or require reversal depending on usage or disposal of goods
The law also restricts ITC in cases where goods are:
- Lost
- Stolen
- Destroyed
- Written off
- Given away as free samples
ITC on Manufacturing Losses
1. Normal Loss (Process Loss)

In manufacturing, some loss is inevitable due to the nature of the process (e.g., evaporation, chemical reaction loss).
Treatment:
- ITC is allowed
- No reversal required
Reason:
Such loss is considered inherent to manufacturing and inputs are still regarded as used in business.
2. Abnormal Loss

Loss beyond standard or expected levels (e.g., fire, negligence, accidents).
Treatment:
- ITC must be reversed
Reason:
Inputs are not considered used for taxable supplies.
ITC on Spoilage and Damaged Goods
Goods may become unusable due to expiry, contamination, or damage.

Key Rule
ITC must be reversed if goods are:
- Destroyed
- Written off in books
This aligns with GST provisions restricting ITC where inputs no longer contribute to taxable supply.
ITC on Free Samples and Gifts
Providing free samples is common for marketing, especially in pharma, FMCG, and consumer goods industries.

GST Position
- ITC is not available on goods given as free samples
- If ITC is already availed → reversal required
Reason
Free samples are not considered “supplies” (no consideration), hence:
- No output tax
- No corresponding ITC benefit
Practical Scenarios
Scenario 1: Manufacturing Loss
A chemical manufacturer uses raw material where 5% loss is standard.
- ITC on entire input → Allowed
Scenario 2: Goods Destroyed in Fire
Finished goods destroyed in warehouse fire.
- ITC attributable to such goods → Reversal required
Scenario 3: Expired Medicines
Pharma company writes off expired stock.
- ITC → Reversal required
Scenario 4: Free Promotional Samples
Company distributes free product samples.
- ITC → Not allowed / reversal required
Key Compliance Points
- Maintain proper documentation for normal loss
- Identify abnormal loss separately
- Reverse ITC in GSTR-3B where required
- Track inventory write-offs regularly
- Evaluate marketing schemes for ITC impact
Important Distinction: Normal vs Abnormal Loss
| Particulars | ITC Treatment |
|---|---|
| Normal process loss | Allowed |
| Abnormal loss | Reversal required |
| Spoilage / destroyed goods | Reversal required |
| Free samples / gifts | Not allowed |
Common Mistakes to Avoid
- Not distinguishing between normal and abnormal loss
- Claiming ITC on free samples
- Ignoring ITC reversal on written-off inventory
- Lack of documentation for production losses
Conclusion
The reversal of ITC on manufacturing losses, spoilage, and free samples is a critical compliance area under GST. While normal process losses do not impact ITC, any loss due to destruction, abnormal events, or free distribution triggers reversal provisions.
Businesses must implement robust tracking systems and internal controls to ensure accurate ITC claims and avoid disputes.
