An inverted duty structure arises when the tax rate on inputs is higher than the tax rate on outputs, leading to accumulated Input Tax Credit (ITC). Under GST, businesses can claim a refund of this accumulated ITC. This comprehensive guide explains the eligibility, calculation, and refund process.
What Is an Inverted Duty Structure?
Definition
An inverted duty structure occurs when:
- The GST rate on inputs (raw materials, components) is higher than
- The GST rate on outputs (finished goods)
Example
| Item | GST Rate |
|---|---|
| Input (Raw Material) | 18% |
| Output (Finished Good) | 5% |
In this case, ITC of 18% is accumulated while output tax is only 5%, leading to unutilised ITC.
Refund Eligibility
Who Is Eligible?
Businesses that:
- Have accumulated ITC due to inverted duty structure
- Have filed GSTR-1 and GSTR-3B
- Are not making exempt supplies
- Have not claimed refund under any other category
What Can Be Refunded?
Refund of unutilised Input Tax Credit that has accumulated due to the inverted duty structure.
Refund Formula Under Rule 89(5)
The Formula
The refund amount is calculated using the formula under Rule 89(5):
Refund Amount = (Turnover of inverted-rated supplies × Net ITC / Adjusted Total Turnover) - Tax payable on inverted-rated supplies
Definitions
- Turnover of inverted-rated supplies: Value of supplies on which the output tax rate is lower than the input tax rate
- Net ITC: Total ITC availed on inputs
- Adjusted Total Turnover: Total turnover adjusted for exempt supplies
- Tax payable: Tax payable on inverted-rated supplies
Important
Refund is available only to the extent of ITC that has accumulated.
