Inverted Duty Structure GST Refund — Unlock Blocked ITC
When the GST rate on your inputs is higher than the rate on your output supplies, Input Tax Credit piles up that you can never fully use. Section 54(3)(ii) of the CGST Act lets you claim a refund of this unutilised ITC via Form RFD-01 with Statement 1 & 1A, computed under the Rule 89(5) formula. TaxClue’s CA team computes, files, and follows up — end to end.

What is Inverted Duty Structure?
Inverted duty structure means the GST rate on inputs (purchases) is higher than the GST rate on output supplies (sales). Example: a footwear maker buying raw material and components at 18% GST but selling the finished product at a lower rate. Input Tax Credit keeps accumulating in the electronic credit ledger faster than it can be used against output tax — locking up working capital.
Section 54(3)(ii) of the CGST Act allows a refund of this unutilised ITC where credit has accumulated because the rate of tax on inputs is higher than the rate on output supplies (other than nil-rated or fully exempt supplies), except for goods or services notified by the Government. The refund amount is capped by the formula in Rule 89(5) of the CGST Rules.
The claim is filed in Form RFD-01 on the GST portal under the category “Refund on account of ITC accumulated due to inverted tax structure”, with Statement 1 (refund computation) and Statement 1A (invoice-wise inward and outward supply details), within 2 years of the relevant date.
Only ITC on Inputs (Goods) Is Refundable Under This Route
“Net ITC” in Rule 89(5) covers ITC on inputs only. ITC on input services and capital goods is not refundable under the inverted duty route — the exclusion of input services was upheld by the Supreme Court in Union of India v. VKC Footsteps (2021). That ITC stays in your credit ledger for set-off, but cannot be encashed here.

Sectors Commonly Hit by Inverted Duty Structure
Textiles & Apparel
Man-made yarn, fibre, and job-work inputs often taxed higher than finished fabric or garments — a classic inversion sector.
Footwear
Components, soles, and adhesives at higher rates than lower-priced finished footwear. Rate changes have narrowed but not eliminated inversion.
Fertilisers & Agro Inputs
Raw materials like ammonia and sulphuric acid at 18% against fertilisers taxed at a concessional output rate.
EV & Components
Electric vehicles at 5% output while many parts, cells, and components attract 18%/28% — heavy ITC accumulation for EV makers.
Utensils, Tractors & Agri Machinery
Steel, castings, and parts at higher input rates than the concessional rate on finished utensils and tractors.
Pharma & Medical Supplies
APIs and packing material frequently taxed above the concessional rate on finished formulations and devices.
Rule 89(5) — Maximum Refund Formula
Maximum Refund Amount =
{(Turnover of inverted rated supply of goods & services × Net ITC) ÷ Adjusted Total Turnover} − {Tax payable on such inverted rated supply × (Net ITC ÷ ITC availed on inputs and input services)}
This is the formula as amended with effect from 5 July 2022 (Notification 14/2022-Central Tax). The second limb apportions the output tax deduction in the ratio of input ITC to total ITC on inputs and input services — a taxpayer-friendly correction over the earlier version, which deducted the full output tax.
| Term in Rule 89(5) | What It Means |
|---|---|
| Net ITC | ITC availed on inputs (goods) only during the period — excludes ITC on input services and capital goods |
| Turnover of inverted rated supply | Value of the inverted-rated supplies of goods and services made during the period |
| Adjusted Total Turnover | Total turnover in the State/UT for the period, excluding exempt supplies (other than zero-rated) and the value of inward supplies on which tax is paid under reverse charge, as defined in Rule 89(4) |
| Tax payable on inverted rated supply | Output tax payable on those inverted-rated supplies for the period |
| ITC availed on inputs and input services | Denominator of the apportionment ratio in the second limb — total ITC availed on inputs plus input services for the period |

Within 60 DaysWhen Inverted Duty Refund is Not Available
| Restriction | Detail |
|---|---|
| Notified goods — proviso to Section 54(3) | The Government can notify goods/services on which no inverted duty refund is allowed (Notification 5/2017-Central Tax (Rate), as amended) — the list has historically included items such as certain woven/knitted fabrics and railway rolling stock parts. Notably, the bar on specified textiles was lifted prospectively from 1 August 2018, but accumulated pre-2018 textile credit was not refundable. The current notified list must be checked for your HSN before filing. |
| ITC on input services | Excluded from “Net ITC” under Rule 89(5) — not refundable under this route (upheld by the Supreme Court in VKC Footsteps, 2021) |
| ITC on capital goods | Not covered by “inputs” — no refund of capital goods ITC under the inverted duty route |
| Nil-rated / fully exempt output supplies | Section 54(3)(ii) applies only where output is taxable at a lower rate — not where output is nil-rated or fully exempt |
| Output rate lowered by a concessional notification on the same goods | CBIC has clarified that where input and output are the same goods and the lower output rate arises from a concessional-rate notification, the inverted duty refund is not intended — a fact-specific area; take advice before filing |
| Composition taxpayers | No ITC is available under the composition scheme, so no inverted duty refund arises |
