Navigating ITC Denials Under Section 16(2)(c) of the CGST Act: Judicial Precedents and Strategies for Bona Fide Assessees
The architecture of the Goods and Services Tax (GST) was originally designed to ensure a seamless flow of credit across the supply chain. However, certain statutory provisions have inadvertently transformed this seamless flow into a labyrinth of compliance hurdles for the honest assessee. At the epicenter of this controversy lies Section 16(2)(c) of the CGST Act, a provision that essentially conditions the availability of Input Tax Credit (ITC) on the actual payment of tax to the government by the supplier.
This statutory mandate creates a profound operational paradox. The law demands that the purchasing assessee guarantee a downstream action—the supplier's remittance of collected taxes to the exchequer—over which the purchaser exercises absolutely no control. As the newly formed Goods and Services Tax Appellate Tribunal (GSTAT) gears up to tackle a staggering 4.8 lakh appeal backlog slated for resolution by June 2026, the interpretation and constitutional validity of this provision will undoubtedly be one of the most critical battlegrounds. The fundamental legal question remains: Is it equitable or constitutionally permissible to penalize a bona fide purchasing assessee for the sovereign defaults of their vendor?
Decoding the Statutory Framework and Practical Implications
To fully comprehend the magnitude of the dilemma, one must analyze how Section 16(2)(c) operates in tandem with other restrictive provisions. The statute explicitly dictates that an assessee is eligible for ITC only if the tax charged in respect of the inward supply has been "actually paid to the Government, either in cash or through utilisation of input tax credit."
This rigid requirement is further compounded by Section 16(2)(aa), a stringent condition ushered in via the Finance Act 2021, which mandates that the details of the supplier's invoice must prominently reflect in the recipient's GSTR-2B statement. The regulatory noose was tightened even further by amendments to Rule 36(4). Historically, prior to January 1, 2022, an assessee enjoyed a slight buffer, permitted to claim provisional ITC up to a 5% margin above the eligible credit reflecting in their GSTR-2B. The amendment ruthlessly eliminated this 5% provisional cushion. Today, ITC claims are strictly capped at the exact quantum populated in the GSTR-2B.
The Working Capital Conundrum
Consider the practical ramifications of these interconnected rules. Suppose an assessee successfully procures raw materials in August 2025. The assessee promptly receives the physical delivery, settles the commercial invoice in full (including the GST component), and securely files away a legally valid tax invoice. However, the vendor exhibits compliance lethargy and delays the filing of their GSTR-1 until October 2025.
Under the uncompromising framework of the amended Rule 36(4), the purchasing assessee is legally barred from availing the ITC in September 2025, despite having fulfilled all substantive conditions of receiving goods and making payment. Because the supplier delayed their filing, the invoice will remain absent from the recipient's September GSTR-2B. The assessee is forced to wait until the generation of the November 2025 GSTR-2B (which will eventually capture the delayed October 2025 filing). This systemic delay inflicts a severe, minimum two-month working capital deficit on the honest assessee.
The Verification Void
The scenario deteriorates further when a supplier successfully files their GSTR-1 (thereby populating the recipient's GSTR-2B) but subsequently absconds with the collected tax instead of depositing it into the government coffers. In such instances, Section 16(2)(c) is invoked by the revenue authorities to ruthlessly deny the ITC to the recipient.
The purchasing assessee may have executed flawless due diligence: verifying the vendor's GSTIN, ensuring the physical receipt of genuine goods, holding immaculate tax invoices, and routing the entire consideration through traceable banking channels. The transaction perfectly mirrors in the GSTR-2B. Yet, the ITC is denied. The glaring flaw in the GST Network (GSTN) architecture is that the GSTR-2B merely confirms the filing of the GSTR-1; it offers zero visibility regarding the actual discharge of tax liability by the supplier. The assessee is essentially punished for failing to verify a data point that the government's own technological infrastructure keeps hidden.
