GST Refund Maze: Identical Input-Output Products & Inverted Duty

Navigating the GST Refund Maze: When Your Primary Input and Output Products Are Identical

I've witnessed countless instances where legitimate GST refund claims have been erroneously rejected by departmental authorities. One particularly vexing scenario that repeatedly surfaces in my chambers involves businesses facing denial of refunds under the inverted duty structure provisions, merely because their primary input and output products are ostensibly identical.

This legal quandary demands immediate attention from CFOs, Finance Directors, and senior taxation professionals who shoulder the responsibility of optimising their organisations' working capital whilst ensuring regulatory compliance.

The Crux of the Matter

Consider this: Your enterprise procures plain T-shirts, applies sophisticated printing techniques using premium inks and threads (attracting 18% GST), and sells the finished printed T-shirts. The departmental authorities reject your refund claim, arguing that since both input and output are "T-shirts," no refund is admissible. This myopic interpretation not only contravenes statutory provisions but also undermines the fundamental principles of value-added taxation.

Dissecting the Legal Framework

The Statutory Mandate

Section 54(3) of the Central Goods and Services Tax Act, 2017, unequivocally provides for refund of accumulated Input Tax Credit (ITC) where:

"The credit has accumulated on account of rate of tax on inputs being higher than the rate of tax on output supplies."

The provision makes no distinction based on whether the primary product undergoes transformation or remains nominally unchanged.

The Expansive Definition of "Inputs"

Section 2(59) of the CGST Act adopts an inclusive approach, defining "input" as:

"Any goods other than capital goods used or intended to be used by a registered person in the course or furtherance of business."

This comprehensive definition encompasses all goods utilised in the business process—not merely the principal raw material. The legislative intent is crystalline: every input contributing to the final product merits consideration.

Evolution of Administrative Clarifications: A Journey from Restriction to Rationality

The Initial Impediment

The CBIC's Circular No. 135/05/2020-GST dated 31st March 2020 initially created substantial obstacles by stating that refunds wouldn't apply where input and output supplies were identical. This circular resulted in widespread denials and financial hardship for compliant taxpayers.

The Watershed Clarification

However, judicial wisdom and commercial reality prevailed. Circular No. 173/05/2022-GST dated 6th July 2022 marked a paradigmatic shift:

"There may however, be cases where though inputs and output goods are same but the output supplies are made under a concessional notification due to which the rate of tax on output supplies is less than the rate of tax on inputs. In such cases... the credit accumulated on account of the same is admissible for refund."

This clarification represents a victory for logical interpretation over bureaucratic rigidity.

Strategic Approach for Finance Leadership

Comprehensive Input Analysis

As financial stewards, you must ensure your teams:

1. Catalogue all inputs meticulously—from primary materials to ancillary consumables

2. Document GST rate differentials across the entire input spectrum

3. Maintain granular records of input utilisation in the manufacturing process

Leveraging Rule 89(5) Formula

The prescribed formula for calculating maximum refund is:

Maximum Refund = [(Turnover of inverted rated supply × Net ITC) ÷ Adjusted Total Turnover] - Tax payable on inverted rated supply

The critical insight: "Net ITC" encompasses credit on all inputs, not merely those with higher tax rates. This interpretation aligns with the Hon'ble Supreme Court's observations in Union of India vs VKC Footsteps.

Countering Departmental Objections: A Practitioner's Toolkit

Objection: "No Value Addition Occurred"

Rebuttal: Value addition through processing, enhancement, or transformation using higher-taxed ancillary inputs creates legitimate grounds for refund. The GST regime recognises incremental value creation, not merely physical transformation.

Objection: "Cannot Segregate Inputs for Calculation"

Rebuttal: The statutory formula contemplates aggregate input tax credit. Artificial segregation requirements find no support in law or legislative intent.

Objection: "Primary Product Remains Unchanged"

Rebuttal: The test isn't product transformation but tax rate differential. The CBIC's own clarification acknowledges this principle explicitly.

Documentation: Your Shield Against Arbitrary Denials

Robust documentation remains paramount:

• Contemporary records of all input purchases with GST invoices

• Manufacturing/processing logs establishing input utilisation

• Detailed workings demonstrating inverted duty calculations

• Legal opinions supporting your interpretation (where contentious)

Recent Judicial Pronouncements: Strengthening Your Position

The Hon'ble Supreme Court's ruling in VKC Footsteps has fortified taxpayers' positions by:

1. Affirming the validity of Rule 89(5)

2. Recognising practical challenges in implementation

3. Urging the GST Council to address anomalies

Post this judgement, the 47th GST Council Meeting's recommendations to include input services further broadens the refund ambit.

Sector-Specific Applications

Textile Industry

The printing, dyeing, and embellishment processes invariably involve high-rated chemicals and specialised materials, creating clear inverted duty scenarios.

Food Processing

Packaging materials, preservatives, and processing aids often attract higher GST rates than finished food products.

Pharmaceutical Manufacturing

Active pharmaceutical ingredients and specialised excipients frequently bear higher tax rates than formulated medicines under concessional notifications.

Comprehensive Conclusions and Strategic Recommendations

The Legal Position: Unassailable

After extensive litigation experience and thorough analysis of statutory provisions, I can state with professional conviction that the legal position favouring refunds in identical input-output scenarios is unassailable. The denial of legitimate refunds based on superficial product similarity constitutes a clear violation of statutory provisions and undermines the GST architecture's foundational principles.

Financial Implications: Substantial

For senior finance professionals, the implications are profound:

1. Working Capital Optimisation: Blocked refunds represent dead capital. Aggressive pursuit of legitimate refunds directly enhances liquidity and financial efficiency.

2. Compliance Cost Reduction: Understanding the correct legal position prevents wasteful litigation and reduces compliance overheads.

3. Competitive Advantage: Organisations successfully claiming refunds maintain pricing flexibility and market competitiveness.

Strategic Action Plan for Finance Leadership

I recommend the following comprehensive approach:

Immediate Actions:

1. Audit existing denials: Review all rejected refund claims from April 2020 onwards

2. Quantify potential recovery: Calculate aggregate refund potential across your operations

3. Engage specialist counsel: Given the technical nature and evolving jurisprudence, expert guidance is indispensable

Medium-term Initiatives:

1. Systemic documentation protocols: Implement robust systems capturing all input utilisation data

2. Regular compliance reviews: Quarterly assessments to identify refund opportunities

3. Proactive engagement: Build relationships with jurisdictional authorities, educating them on legal provisions

Long-term Strategy:

1. Industry collaboration: Join forces with trade associations to advocate for clearer guidelines

2. Judicial remedies: Where administrative channels fail, don't hesitate to approach Appellate Authorities and High Courts

3. Policy advocacy: Engage with GST Council through appropriate channels for permanent resolution

The Practitioner's Perspective

Having argued numerous cases before the Hon'ble Supreme Court and various High Courts on indirect taxation matters, I've observed that success in refund claims often hinges on:

1. Meticulous preparation: Courts appreciate well-documented, logically presented cases

2. Legal precision: Citing correct provisions and precedents demonstrates professional competence

3. Commercial substance: Explaining the business rationale helps judicial authorities appreciate practical implications

Risk Mitigation Strategies

While pursuing refunds aggressively, implement safeguards:

1. Maintain litigation reserves: Provision for potential adverse outcomes

2. Document contemporaneously: Real-time documentation prevents post-facto challenges

3. Seek advance rulings: For substantial or recurring transactions, clarity through advance rulings minimises disputes

The Economic Imperative

From a macroeconomic perspective, the refund mechanism prevents cascading taxation and maintains GST's character as a consumption tax. Finance professionals must view refund claims not merely as compliance exercises but as:

• Fiduciary duties to shareholders

• Working capital management tools

• Competitive strategy elements

Final Observations

The journey from the restrictive Circular 135/05/2020 to the enlightened Circular 173/05/2022 demonstrates that persistent advocacy, grounded in legal principles, yields results. The CBIC's evolving stance vindicated the position many of us have maintained in courts and tribunals.

For CFOs and Finance Directors reading this exposition, I urge you to:

1. Reassess your refund strategies immediately

2. Empower your teams with proper legal understanding

3. Pursue legitimate claims with renewed vigour

The law stands firmly on your side. The clarifications are unambiguous. The judicial precedents are supportive. What remains is strategic execution.

A Closing Thought

In my three decades of practice, I've witnessed how proactive financial leadership, armed with correct legal understanding, transforms regulatory challenges into competitive advantages. The GST refund mechanism, properly understood and strategically deployed, exemplifies this principle.

The inverted duty structure provisions weren't enacted as mere statutory ornaments—they serve the vital purpose of preventing tax cascading and maintaining economic efficiency. When departmental authorities deny legitimate refunds based on oversimplified interpretations, they not only harm individual businesses but undermine the GST system's integrity.

As custodians of your organisations' financial health, you bear the responsibility—and possess the opportunity—to convert these legal provisions into tangible financial benefits. The path is clear, the law is supportive, and the potential rewards are substantial.

Remember: In taxation, as in litigation, fortune favours the well-prepared and legally informed
