Safeguarding the Honest Assessee: Judicial Triumphs Against ITC Denial for Vendor Defaults Under GST
The fundamental architecture of any value-added tax system rests on the seamless flow of input credits. However, in the Indian context, few statutory mandates have sparked as much widespread litigation, operational distress, and interpretational debate as Section 16(2)(c) of the Central Goods and Services Tax Act, 2017. In its most literal interpretation, this specific clause restricts an assessee from claiming Input Tax Credit (ITC) unless the upstream vendor has actually deposited the collected tax into the government treasury. This places the purchasing assessee in an incredibly precarious position, making their legitimate tax credits entirely dependent on the compliance behavior of a third party—a factor over which the purchasing assessee exercises zero operational control or visibility.
Since the inception of the GST regime in 2017, departmental authorities nationwide have frequently weaponized this statutory condition. Countless honest businesses have faced exorbitant demand notices and arbitrary credit reversals merely because their suppliers absconded or failed to file their respective returns. Fortunately, a robust judicial consensus has begun to materialize over the past year. A triad of monumental High Court judgments—culminating with the Karnataka High Court’s decisive intervention in M/s Instakart Services Private Limited vs. Union of India (WP No. 4917 of 2021, dated 09.02.2026), alongside the Gauhati High Court’s ruling in National Plasto Moulding vs. State of Assam (2024) 21 Centax 182, and the Tripura High Court’s verdict in M/s Sahil Enterprises vs. Union of India (W.P.(C) 688/2022, dated 06.01.2026)—has fundamentally reshaped the legal landscape.
This comprehensive analysis dissects the profound legal doctrines established in these rulings, offering tax practitioners and corporate counsels a strategic framework to defend the genuine assessee against unjust ITC denials.
Decoding the Statutory Bottleneck: The Mechanics of Section 16(2)
To fully grasp the magnitude of these judicial pronouncements, one must first deconstruct the statutory hurdles placed before the assessee. Section 16(2) of the Central Goods and Services Tax Act, 2017 outlines a rigid set of cumulative prerequisites that a registered entity must satisfy to successfully unlock ITC:
- The assessee must physically possess a legally compliant tax invoice or an equivalent prescribed document.
- The actual delivery and receipt of the underlying goods or services must be established.
- The transaction must be properly reflected in the auto-generated GSTR-2B statement, without being subjected to any restrictions under
Section 38, as mandated bySection 16(2)(aa). - The tax levied on the specific transaction must have been genuinely remitted to the exchequer by the supplier, either via cash ledger payments or permissible ITC utilization, as dictated by
Section 16(2)(c). - The purchasing assessee must have duly furnished their periodic returns under
Section 39, as required bySection 16(2)(d).
The primary catalyst for the ongoing legal friction is the condition embedded in clause (c). When read strictly, this provision implies that an assessee who has diligently paid the full invoice value—including the GST component—to the vendor, secured the necessary documentation, consumed the goods in the course of business, and maintained immaculate return filing records, can still be stripped of their ITC. If the vendor maliciously retains the tax amount and defaults on their GSTR-3B obligations, the innocent buyer is penalized.
Compounding this inequity is the absolute lack of any statutory apparatus allowing the recipient to audit or enforce the supplier's tax remittances. Information regarding a vendor's tax payments is strictly confidential. Similar to Section 28 of the legacy VAT legislations, the current GST framework guards supplier return data against third-party scrutiny. Furthermore, the introduction of Section 16(2)(aa) and Rule 36(4) tightened the noose by capping ITC claims strictly to the data populated in the GSTR-2B, which is entirely contingent on the supplier’s diligence in filing their GSTR-1 and GSTR-3B. The constitutional validity and practical fairness of these intertwined provisions formed the primary battleground in the aforementioned triad of cases.
