Manufacturers and traders operating in sectors such as textiles, footwear, fertilizers, solar equipment, and printing face a recurring working capital bottleneck known as the inverted duty structure. When raw materials are taxed at 12% or 18% but final outward supplies attract 5%, the input tax credit accumulated on purchases always outpaces the output tax liability due on sales. The unutilised balance sits trapped in the electronic credit ledger, straining business cash flows. Section 54(3)(ii) provides relief by allowing a refund of this accumulated credit, but securing the money requires strict adherence to statutory formulas, judicial precedents, and portal documentation.
Statutory framework under Section 54(3)(ii)
The substantive right to claim a refund of unutilised input tax credit is established by Section 54(3) of the CGST Act. While the general rule under GST prohibits cash refunds of unutilised credit, the statute carves out two express exceptions under its first proviso:
“a registered person may claim refund of any unutilised input tax credit at the end of any tax period: Provided that no refund of unutilised input tax credit shall be allowed in cases other than- (i) zero rated supplies made without payment of tax; (ii) where the credit has accumulated on account of rate of tax on inputs being higher than the rate of tax on output supplies (other than nil rated or fully exempt supplies), except supplies of goods or services or both as may be notified by the Government on the recommendations of the Council:” Section 54(3), CGST Act
To qualify under Section 54(3)(ii), your business must satisfy four distinct legal conditions:
- Higher tax rate on inputs: The GST rate applicable to your inward supplies of inputs must exceed the rate of tax charged on your outward supplies.
- Exclusion of nil-rated or exempt supplies: If your output supply is nil-rated or wholly exempt under Section 11, the accumulation does not qualify for an inverted duty refund. In that case, input credit must be reversed under Rule 42.
- Exclusion of notified items: The Government has notified specific goods where inverted duty refunds are barred, including certain edible oils and coal under Notification No. 09/2022-Central Tax (Rate), as well as rail locomotives and construction services.
- No duty drawback or IGST refund claim: Under the second proviso to Section 54(3), no refund is permissible if the supplier claims drawback of central tax or claims refund of integrated tax paid on such supplies.

The Supreme Court ruling in VKC Footsteps: input services excluded
One of the most consequential legal battles in GST centered on whether the refund under Section 54(3)(ii) covers input services like job work, freight, and rent, or is restricted only to physical goods (inputs). In Union of India vs VKC Footsteps India Pvt Ltd (Civil Appeal No. 4810 of 2021), the Supreme Court delivered its definitive verdict.
The Supreme Court resolved conflicting decisions between the Gujarat High Court (which had favored refund of input services) and the Madras High Court. The apex court held that:
- Section 54(3)(ii) uses the word inputs, which is defined under Section 2(59) as goods other than capital goods. The legislature intentionally excluded input services (defined under Section 2(60)) and capital goods (defined under Section 2(19)) from the refund entitlement.
- Refund is a statutory concession created by parliament, not an inherent constitutional right. The court cannot rewrite the statutory formula to expand the scope of refund beyond the plain language of the Act.
- However, the Supreme Court pointed out an inherent mathematical inequity in the original Rule 89(5) formula. The court observed that while output tax liability was discharged using credit from both inputs and input services, the old formula deducted the entire output tax from input credit alone, causing an artificial denial of legitimate input refund. The court urged the GST Council to redress this anomaly.
Common mistake: Never include GST paid on input services (such as factory rent, legal fees, testing charges, or maintenance) or capital goods (machinery purchases) in your refund claim amount. Doing so triggers a show-cause notice in Form GST RFD-08 and potential recovery with interest under Section 50.
The amended Rule 89(5) formula: Notification 14/2022-Central Tax
To implement the directions of the Supreme Court and resolve the mathematical distortion, the CBIC issued Notification No. 14/2022-Central Tax on 5 July 2022, formally substituting the formula in Rule 89(5) of the CGST Rules. CBIC Circular No. 181/13/2022-GST clarified that this amended formula applies prospectively to all refund applications filed on or after 5 July 2022.
The statutory formula under Rule 89(5) reads:
Understanding each term in the formula
- Turnover of inverted rated supply: The aggregate value of inverted rated supplies of goods and services made during the relevant tax period without any tax component.
- Net ITC: Input tax credit availed on inputs (raw materials, packing materials, consumables) during the relevant tax period. It excludes ITC on input services, ITC on capital goods, and any credit claimed under Rule 89(4A) or (4B).
- Adjusted Total Turnover: Total turnover in the State or Union Territory during the relevant period, excluding exempt supplies other than zero-rated supplies.
- Tax payable on inverted rated supply: The actual output tax liability generated on the outward inverted supply.
- ITC availed on inputs and input services: The total eligible credit availed in Table 4(A) of Form GSTR-3B on both inputs and input services combined during the relevant period.
The second part of the formula is the key reform: instead of subtracting the entire output tax payable, it multiplies that tax by the fraction (Net ITC ÷ Total ITC on inputs and input services). This ensures that output tax is set off proportionally against input services credit, leaving more input credit available for your cash refund.
Worked mathematical example: old formula vs amended formula
Consider Precision Footwear LLP, a manufacturing unit in Tamil Nadu. The firm purchases raw rubber and polymers at 18% GST and manufactures finished footwear sold at 5% GST. Over a tax period, its figures in books and filed GSTR-3B are as follows:
| Particulars | Classification | Amount |
|---|---|---|
| Turnover of inverted rated supplies (footwear sold at 5%) | Inverted turnover | ₹50,00,000 |
| Turnover of standard rated supplies (accessories sold at 18%) | Other turnover | ₹50,00,000 |
| Adjusted Total Turnover | Total turnover | ₹1,00,00,000 |
| Output tax payable on inverted supplies (5% of ₹50,00,000) | Tax payable | ₹2,50,000 |
| ITC availed on raw materials (inputs) | Net ITC | ₹6,00,000 |
| ITC availed on job work and factory rent (input services) | Service ITC | ₹2,00,000 |
| Total ITC on inputs and input services | Formula denominator | ₹8,00,000 |
| ITC availed on new moulding machines (capital goods) | Excluded | ₹1,00,000 |
Step-by-step computation under the amended formula
- Proportional input credit (Term 1):
(Turnover of inverted supply × Net ITC) ÷ Adjusted Total Turnover
(₹50,00,000 × ₹6,00,000) ÷ ₹1,00,00,000 = ₹3,00,000 - Proportionate output tax deduction (Term 2):
Credit ratio =Net ITC ÷ Total ITC on inputs and input services
Credit ratio =₹6,00,000 ÷ ₹8,00,000 = 0.75 (75%)
Proportionate tax deduction =₹2,50,000 × 0.75 = ₹1,87,500 - Maximum refundable amount:
Maximum Refund = Term 1 − Term 2
Maximum Refund = ₹3,00,000 − ₹1,87,500 = ₹1,12,500
Impact of the statutory amendment
Under the pre-July 2022 formula, the entire output tax of ₹2,50,000 was subtracted directly from Term 1 (₹3,00,000), yielding a refund of only ₹50,000. Under the amended formula, the refund increases to ₹1,12,500. The difference of ₹62,500 (25% of ₹2,50,000) represents the tax liability discharged using input services credit, which is no longer deducted from your input refund entitlement.
Step-by-step procedure to file Form GST RFD-01 on the portal
Once you verify that your credit accumulation satisfies Section 54(3)(ii) and compute the refundable amount, submit your claim electronically through the GST common portal.
- Verify return compliance: All Form GSTR-1 and Form GSTR-3B returns for the refund period and preceding periods must be filed. You cannot file a refund application if any prior return remains pending.
- Prepare Statement 1A: Download the official offline utility for Statement 1A from tutorial.gst.gov.in. Enter invoice-level inward supply details of inputs (invoice number, date, GSTIN of supplier, taxable value, and tax amounts) and details of outward inverted supplies. Validate the sheet, generate the JSON file, and upload it on the refund dashboard.
- Auto-population of formula figures: Upon uploading Statement 1A, the portal validates the invoice data against filed returns and auto-populates the turnover and tax payable fields. Enter your Net ITC (inputs only) and eligible service ITC.
- Credit ledger debit validation: The portal determines the eligible refund amount as the lowest of three limits:
- Maximum refund amount calculated under Rule 89(5).
- Balance in your electronic credit ledger at the end of the tax period for which refund is claimed.
- Balance in your electronic credit ledger at the time of submitting Form GST RFD-01.
- Upload supporting annexures: Upload your self-certified reconciliation statement, copy of purchase register, and an undertaking that no duty drawback or IGST refund has been claimed. If the refund claim exceeds ₹2,00,000, attach a certificate issued by a practicing Chartered Accountant or Cost Accountant certifying that the tax incidence has not been passed on, ensuring compliance with unjust enrichment rules under Section 54(4).
- Sign and submit: Submit the application using DSC (mandatory for companies and LLPs) or EVC. The portal debits the requested refund amount from your Electronic Credit Ledger and generates an Application Reference Number (ARN) in Form GST RFD-02.
Why GSTR-2B reconciliation is mandatory before filing RFD-01
Inward invoices claimed in Statement 1A are scrutinised rigorously by jurisdictional refund officers. Under Circular No. 125/44/2019-GST and Circular No. 173/05/2022-GST, tax officers verify every input invoice in Statement 1A against the recipient's auto-populated GSTR-2B statement.
If an input invoice appears in your purchase register but is missing from GSTR-2B because the vendor failed to file GSTR-1, the refund officer will reject that invoice from Net ITC. This reduces your Net ITC numerator, lowers your Term 1 calculation, and can result in partial sanction or issuance of a deficiency memo in Form GST RFD-03. In addition, claiming credit in GSTR-3B that exceeds GSTR-2B triggers an automated mismatch intimation in Form DRC-01C under Rule 88D.
Notice risk: A single mismatch between Statement 1A, Table 4(A)(5) of GSTR-3B, and GSTR-2B can hold up your entire refund claim. Always reconcile your input register with GSTR-2B before filing the monthly return, and exclude any invoices from Statement 1A where the supplier has not uploaded the invoice.
Common pitfalls in inverted duty structure claims
- Including input services in Net ITC: Net ITC must strictly represent goods other than capital goods. Including freight, job work, insurance, or professional charges in Net ITC violates Rule 89(5) and the VKC Footsteps ruling.
- Claiming refund on trading goods without value addition: Circular No. 173/05/2022-GST clarifies that refund under Section 54(3)(ii) is available where inputs and output supplies are identical, provided the input tax rate is higher than output tax rate (for example, due to rate revisions). However, ensure the inversion is genuine and not an artificial mismatch caused by concessional rate exemptions.
- Failing to track credit ledger balance: If you utilise credit ledger balances to discharge other output liabilities before filing RFD-01, your refundable amount drops to the remaining ledger balance at the time of filing, even if your formula entitlement was higher.
- Ignoring the two-year limitation period: Under Section 54(1) read with Explanation (2)(h), the refund application must be submitted within two years from the due date of furnishing the Section 39 return for the relevant period. Late claims are time-barred by law.
- Submitting Statement 1A with data entry mismatches: Invoice numbers in Statement 1A must match the exact formatting (including hyphens and slashes) reported by suppliers in their GSTR-1. Discrepancies cause offline utility validation errors.
Reconcile your inward invoices and filter input credit
Prepare clean Statement 1A schedules without invoice mismatches. Match your purchase register against GSTR-2B, separate eligible raw material inputs from input services and capital goods, and prevent deficiency memos. Your GSTR-2B and purchase register files are read in your browser and never uploaded to any server.

Frequently asked questions
Can I claim GST refund on input services under the inverted duty structure?
No. The Supreme Court in the VKC Footsteps ruling affirmed that Section 54(3)(ii) restricts inverted duty structure refunds strictly to unutilised ITC accumulated on inputs (goods). Credit on input services and capital goods cannot be claimed as a refund under Rule 89(5).
How did Notification 14/2022-Central Tax change the Rule 89(5) formula?
Before July 2022, the formula deducted the entire output tax payable on inverted supplies from the proportional input ITC. The substituted formula apportions the output tax deduction between inputs and input services based on their credit ratio, preventing unfair reduction of refundable input credit.
What is Statement 1A in Form GST RFD-01?
Statement 1A is the mandatory invoice-level schedule uploaded with Form GST RFD-01. It contains inward invoice details of inputs and outward invoice details of inverted supplies to validate eligibility against filed returns and GSTR-2B.
What is the time limit for filing an inverted duty structure refund application?
Under Section 54(1), the refund application must be filed within two years from the relevant date. For inverted duty structure claims, Explanation (2)(h) to Section 54 defines the relevant date as the due date for furnishing the return under Section 39 for the period in which the refund claim arises.
Can capital goods credit be included in Net ITC under Rule 89(5)?
No. Explanation (a) to Rule 89(5) defines Net ITC as input tax credit availed on inputs during the relevant period. Capital goods credit is excluded from both the numerator and denominator of the refund formula.
