ITAT & High Court Ruling: Retrospective Applicability of Clarificatory Formula in Rule 89(5) for Inverted Duty Refunds
Reference: Section 54 of the CGST Act, 2017 | Rule 89(5) of the CGST Rules, 2017
Period: November 2018 to April 2019
Status: In Favor of Assessee (Matter Remanded)
1. The Core Dispute: Denial of Refund under Old Formula
The petitioner, a taxpayer under an Inverted Duty Structure (where tax on inputs is higher than tax on output supplies), sought a refund of accumulated Input Tax Credit (ITC) for the period between November 2018 and April 2019.
Revenue’s Stand: The adjudicating and appellate authorities rejected the refund applications in 2021 and 2022. They relied on the then-existing Rule 89(5) formula, which was seen as restrictive and often resulted in a lower or nil refund amount because it did not proportionately account for the utilization of ITC from input services.
Assessee’s Stand: The petitioner challenged the rejection, arguing that the subsequent amendment to the formula in Rule 89(5) was intended to fix an inherent anomaly and should apply to pending claims.
2. Legal Analysis: Clarificatory vs. Prospective Amendments
The High Court examined the nature of the amendment to the formula in Rule 89(5), which was modified via Notification No. 14/2022-Central Tax (following recommendations from the 47th GST Council meeting and observations by the Supreme Court in the VKC Footsteps case).
I. The “Clarificatory and Curative” Nature
The Court held that the amendment to the formula was not a “new” rule but a rectification of a defect in the existing calculation mechanism.
The Ruling: Amendments that are curative or intended to remove an anomaly are generally retrospective in operation. Even if the rejection orders were passed before the official notification of the amendment, the taxpayer’s continued agitation (via writ/appeals) kept the claim “alive.”
II. The Modified Formula
The amended formula now ensures that the “tax payable on inverted rated supply” is reduced in the same proportion as the ITC availed on inputs and input services.
Impact: This modification prevents the “Net ITC” (which only includes inputs) from being unfairly depleted by the total output tax, leading to a more equitable and accurate refund.
3. Final Ruling: Fresh Consideration Directed
The Court set aside the rejection orders of the primary and appellate authorities.
Verdict: The applications are to be reconsidered afresh.
Directive to AO: The primary authority is directed to apply the modified/amended formula in Rule 89(5) to the petitioner’s claims for the relevant period (Nov 2018 – April 2019).
Outcome: This ensures the taxpayer receives the “rightful” refund as intended by the substantive provisions of Section 54(3).
Key Takeaways for Taxpayers
Revisiting Old Rejections: If your Inverted Duty Structure refund was rejected or reduced under the old formula for periods prior to July 2022, you may have grounds to seek a re-adjudication based on this “retrospective/clarificatory” principle.
Supreme Court Precedent: The Supreme Court in Union of India vs. Tirth Agro Technology (2025) and Ascent Meditech has affirmed that this curative amendment supports substantive justice over technical timing.
Calculation Check: Always ensure that your “Net ITC” excludes capital goods and that your “Adjusted Total Turnover” excludes exempt supplies to ensure your claim is not rejected on factual grounds.
