Making Sense of GST Inverted Duty Refunds: What If Your Main Input and Output Have the Same Rate?
How the latest GSTAT ruling changes refund eligibility for businesses using higher-taxed packing or ancillary materials
The Issue: Inverted Duty Refund When Input and Output GST Rates Are the Same
An inverted duty structure under GST arises when the tax rate on inputs (raw materials, packing materials, etc.) is higher than the rate on output supplies (finished goods). Section 54(3)(ii) of the Central Goods and Services Tax (CGST) Act, 2017, allows for a refund of unused Input Tax Credit (ITC) in such cases, but taxpayers have long debated one key question: What if the main material you use to make your product (principal input) and the product you sell (output) are taxed at the same GST rate, but some of your other materials are taxed higher?
A recent ruling by the GST Appellate Tribunal (GSTAT), Kolkata Bench, settles this issue. The case—The Pr. Commissioner CGST & CX, Siliguri Commissionerate vs M/s Dalmia Tea Packaging Pvt Ltd [2026 VIL 81 GSTAT KOL]—confirms that refund eligibility hinges on the GST rate of any input, not just the principal input.
GSTAT's Clarification: Focus on All Inputs, Not Just Principal Inputs
What the Law Says
- Section 54(3)(ii) of CGST Act: Enables refund of accumulated ITC when the "rate of tax on inputs" is higher than that on output supplies.
- Section 2(59): Defines "input" as goods (excluding capital goods) used in the course or furtherance of business.
The Key Takeaway
- The law refers to "inputs" in plural, i.e., all goods (not limited to the principal input) used in making the output supply.
- If any ancillary input—such as packing material or an ingredient—is taxed at a higher rate than your output, you can claim the refund of the accumulated ITC, even if the main input used is taxed at the same rate as the output.
Example:
Suppose a tea company buys loose tea leaves (taxed at 5%) and uses cartons, labels, and containers (taxed at 12% or 18%) to package the tea. The output (packaged tea) is also sold at 5%. Even though both the principal input (tea leaves) and output have the same GST rate (5%), the company can claim a refund for the accumulated ITC on higher-taxed packing materials.
Why Packing Materials Matter
Packing and ancillary materials—cartons, labels, containers, foils—are common in many industries. The CBIC (Central Board of Indirect Taxes and Customs) clarified in Circular No. 79/53/2018 that such materials are covered as "inputs." The GSTAT cited this circular, supporting that refund eligibility exists for ITC on these materials when they attract higher GST rates compared to the output.
Implications for Manufacturers and Traders
Industries affected include packaged foods, pharmaceuticals, printing, and any business where the primary raw material and finished product share a GST rate, but ancillary materials are taxed higher. This GSTAT ruling means that such businesses can continue to claim refunds for accumulated ITC due to inverted duty—helping avoid GST becoming an irrecoverable cost.
The Tribunal's Reasoning in Brief
- Statute uses the broad term "inputs," not just principal input.
- Excluding refund eligibility when principal input and output rates match goes against legislative intent.
- Emphasis is on tax neutrality and avoiding tax cascading.
When You Can—and Cannot—Claim the Inverted Duty Refund
| Situation | Refund Eligible? |
|---|---|
| Principal input & output both at same GST rate; some ancillary input taxed higher | Yes |
| All inputs (including ancillary) and output have same GST rate | No |
| Some principal/ancillary inputs taxed lower or equal to output | No refund for those inputs |
Remember: Capital goods are excluded from the inverted duty refund provision.
What to Do Next
- Review your input mix: Check invoices to determine if any of your materials used in making your product are taxed at a higher rate than your product.
- Maintain documentation: Retain proof of the use of these higher-taxed materials (purchase invoices, stock registers, etc.).
- Calculate your refund: Accumulate ITC on qualifying inputs and claim refund under the inverted duty structure via GST portal.
- Refer to CBIC Circular 79/53/2018: For clarity on what constitutes an eligible input (e.g., packing materials).
Who Benefits Most
- Manufacturers using higher-GST-rate packaging/materials for low-GST-rate goods (e.g., tea packers, pharma, food processors).
- Businesses previously unsure of refund eligibility where only ancillary inputs attracted higher tax rates.
Frequently asked questions
Does the principal input and output supply need to be taxed at different GST rates to claim an inverted duty refund?
No. Even if the main input and output are taxed at the same rate, a refund is allowed if any ancillary input (like packing materials) is taxed at a higher rate.
What kinds of ancillary inputs qualify for inverted duty refund under GST?
Any non-capital goods used in making the output supply, such as packing materials (labels, cartons, containers), qualify if taxed at a higher rate than the output.
Are capital goods included in calculating ITC refund under the inverted duty structure?
No. Only inputs (goods excluding capital goods) are considered for refund under Section 54(3)(ii) of the CGST Act, not capital goods.
How should manufacturers track eligibility for inverted duty refunds?
Manufacturers should maintain clear records of all input purchases, check GST rates on each, and ensure documentation shows use in making the output goods.
What if all my business inputs and outputs are taxed at the same GST rate?
In that case, you are not eligible for an inverted duty refund, as there is no rate differential to trigger the refund provision.
