GST Refund for Inverted Duty Structure: Eligibility & Process
When the GST on your inputs is higher than the GST on your finished product, input tax credit piles up and never gets used. This is the inverted duty structure, and GST law allows you to claim a refund of that accumulated credit. This guide explains the GST refund for an inverted duty structure — eligibility, the refund formula, restrictions, and the process.
What Is an Inverted Duty Structure?
An inverted duty structure arises when the rate of tax on inputs is higher than the rate of tax on the output supply. For example, a manufacturer buys raw materials taxed at 18% but sells the finished product taxed at 5%. The result is a continuous build-up of input tax credit that cannot be fully set off against output tax.
Who Can Claim This Refund?
Any registered person whose credit accumulates due to an inverted rate structure can claim a refund of the unutilised input tax credit on inputs. However, there are exceptions — certain notified goods (and some services) are not eligible even if their structure is inverted.
The Refund Formula
The refund of unutilised ITC under an inverted duty structure is computed by a prescribed formula. In essence:
Maximum Refund = (Turnover of inverted-rated supply × Net ITC ÷ Adjusted Total Turnover) − Tax payable on such inverted-rated supply
“Net ITC” refers to input tax credit on inputs (goods) — credit on input services and capital goods is generally excluded from this computation. Correct computation is the single most important step, as errors here cause most rejections.
Key Restrictions
- Refund is allowed on inputs only, not on input services or capital goods.
- Certain notified products are excluded from the inverted-duty refund.
- The claim must be filed within two years from the relevant date.
Step-by-Step Process
1. Confirm Eligibility
Verify that your supply has a genuine inverted structure and is not on the excluded list.
2. Compute the Refund
Apply the prescribed formula carefully, using only eligible Net ITC on inputs.
3. File RFD-01
File the refund application in Form RFD-01 with the statement of inward and outward supplies and the computation.
4. Respond to Queries and Receive Sanction
Address any deficiency memo, and the officer sanctions the eligible refund through RFD-06. For the overall flow, see the GST refund process.
Documents Required
- Statement of invoices of inputs and output supplies.
- Refund computation as per the formula.
- Filed GSTR-1 and GSTR-3B for the period.
- Declaration/undertaking as prescribed.
