How to Claim GST Refund on Inverted Duty Structure in India – Complete Guide

Many manufacturers and businesses in India face a common issue under GST — inverted duty structure, where the tax paid on inputs is higher than the tax charged on outputs. This situation leads to accumulation of Input Tax Credit (ITC) and blocks working capital for businesses.

The Indian GST system allows taxpayers to claim refunds in such cases through the GST Portal. However, many businesses struggle with the documentation, calculations, and compliance required to successfully receive the refund.

In this guide, we explain what inverted duty structure is, who is eligible for a refund, and the step-by-step process to claim GST refund in India.

What is Inverted Duty Structure in GST?

An Inverted Duty Structure (IDS) occurs when the tax rate on inputs is higher than the tax rate on the finished goods or services supplied.

Because of this mismatch, businesses accumulate excess Input Tax Credit (ITC) that cannot be fully utilized.

Example

Particular	GST Rate
Raw Material (Input)	18%
Finished Product (Output)	5%

Since the output tax is lower than the input tax, the business cannot utilize the entire ITC. The remaining ITC becomes blocked capital.

This is commonly seen in industries such as:

• Textile manufacturing
• Corrugated box and packaging industry
• Footwear manufacturing
• Pharmaceutical products
• Certain engineering products

To solve this issue, the government allows businesses to claim GST refund on accumulated ITC due to inverted duty structure.

Who is Eligible to Claim GST Refund Under Inverted Duty Structure?

Businesses can claim a refund when the following conditions are satisfied:

1. The GST rate on inputs is higher than the GST rate on output supplies.
2. The excess ITC is accumulated due to the inverted tax structure.
3. The taxpayer has filed GSTR-1 and GSTR-3B returns.
4. The refund claim is filed within the prescribed time limit.
5. Proper documentation and invoices are maintained.

However, refund is not allowed for certain goods and services notified by the government.
