Understanding GST Inverted Duty Structure and Refund of ITC Under Section 54(3)
The Goods and Services Tax (GST) framework aims to create a uniform indirect tax structure across India. However, certain industries face challenges due to the Inverted Duty Structure (IDS)—a situation where the tax rate on inputs is higher than the tax rate on outward supplies. To address this issue, GST law allows taxpayers to claim a refund of accumulated Input Tax Credit (ITC) under Section 54 of the CGST Act read with Rule 89(5) of the CGST Rules.
This blog provides a detailed, professional, and easy-to-understand overview of the inverted tax structure, eligibility for refunds, calculation methods, restrictions, and key judgments.
What Is an Inverted Duty Structure (IDS) Under GST?
An Inverted Duty Structure arises when:
GST rate on inputs (goods/services) > GST rate on outward supply of goods or services.
This leads to accumulation of Input Tax Credit because a taxpayer pays more GST on purchases than the GST collected on sales.
Example:
GST on inputs (raw material) = 18%
GST on outward supply (finished goods) = 5%
Here, the taxpayer will accumulate ITC due to the higher input tax.
Statutory Provision: Section 54(3) of the CGST Act
Section 54(3) allows a registered person to claim refund of unutilized ITC in two situations:
Zero-rated supplies (exports/SEZ) made without payment of tax.
Accumulation due to inverted duty structure, subject to government-notified restrictions.
However, refund is not allowed in the following cases:
If the supplier claims duty drawback of central tax.
If the output supply is nil-rated or fully exempt.
If notification restricts refund for certain goods/services.
Calculation of Refund Under Rule 89(5)
Rule 89(5) provides the formula for computing refund:
Refund Amount = (Turnover of inverted rated supply × Net ITC ÷ Adjusted Total Turnover) – Tax payable on such inverted rated supply
Key Definitions
Net ITC – ITC availed on inputs during the period (INPUTS ONLY – not input services or capital goods).
Turnover of inverted rated supply – Value of such supplies made during the period.
Important Note:
Refund of Input Services and Capital Goods is NOT allowed as per the current rule.
Restrictions on Inverted Duty Refund
The Government has restricted refunds for certain goods/services under Section 54(3).
Examples include:
Fabrics under Chapters 50–55
Footwear industry at certain periods
Specific items notified via various GST rate notifications
Taxpayers must verify if their product/service falls under the restricted list before applying.
Important Judicial Pronouncements
Several High Courts have ruled on the scope of refund under IDS:
VKC Footsteps India Pvt. Ltd. vs Union of India
Gujarat High Court allowed refund on input services, but Supreme Court overruled this part.
Supreme Court upheld that refund is restricted to inputs only, aligning with Rule 89(5).
Tvl. Transtonnelstroy Afcons JV (Madras HC)
Confirmed that input services are excluded and refund is limited to inputs.
These judgments solidify that no refund is allowed on input services under the current legal framework.
Documentation Required for Claiming Refund
A registered person must file RFD-01 on the GST portal along with:
GSTR-1 and GSTR-3B for the period
Purchase and sales invoices
Statement 1A under Rule 89(5)
CA certificate (if refund > ₹2 lakhs)
Declaration of non-passing of tax burden (unjust enrichment)
Step-by-Step Refund Filing Process
Login to GST portal → Services → Refunds → Application for Refund.
Choose “Refund on account of inverted duty structure”.
Select tax period.
Upload required documents.
Validate turnover figures and ITC details.
File application with DSC/EVC.
Once submitted, the jurisdictional officer will examine the claim and issue refund order RFD-06 after due verification.
Practical Tips for Taxpayers
Ensure accurate classification of inputs and output supplies.
Regularly reconcile ITC between GSTR-2B and purchase register.
Maintain proper documentation to avoid delays or rejections.
Verify if your product category is restricted from IDS refunds.
Keep track of circulars and notifications affecting refund eligibility.
Conclusion
Refund of unutilized ITC due to an inverted duty structure under Section 54(3) is a crucial relief for industries where input taxes exceed output taxes. While the law restricts refunds to inputs only, understanding the correct calculation, documentation, and compliance requirements ensures smooth processing of claims.
Businesses should stay informed about legal updates and government notifications to ensure optimal GST planning and cash flow management.
