Supreme Court Confirms: Input Tax Credit Denied if Supplier Fails to Deposit GST

What Happened

The Supreme Court of India has delivered a landmark judgment affirming the Gujarat High Court's earlier decision that Input Tax Credit (ITC) cannot be claimed by a recipient-buyer if the supplier has failed to deposit the GST collected on the supply. This ruling clarifies a critical pain point in GST administration where the entire chain of credit is contingent upon proper tax remittance at each stage.

The judgment reinforces the principle that ITC eligibility is not merely transactional—that is, contingent only on the existence of a valid tax invoice—but is conditional on actual tax payment by the supplier to the exchequer. This represents a significant tightening of ITC entitlement rules and places substantial responsibility on recipients to ensure their suppliers comply with GST deposit obligations before claiming credit.

While the exact case details and date of the Supreme Court order are referenced via the Gujarat High Court ruling, this judgment represents settled law on a matter that has generated considerable litigation and compliance uncertainty across India's GST framework since its implementation in 2017.

Why It Matters

This ruling has profound implications for how GST input credit operates in practice. Under the GST regime, ITC is a fundamental right available to registered taxpayers, but it has always been subject to compliance conditions. The Supreme Court's affirmation now places explicit emphasis on the supplier's actual remittance of tax—not just issuance of a compliant invoice—as a prerequisite for the buyer's credit entitlement.

The judgment addresses a structural vulnerability in the GST model: unscrupulous suppliers could issue valid invoices without depositing the tax, enabling fraudulent credit claims downstream while evading payment. By conditioning ITC on actual deposit, the Court has effectively created a verification requirement for buyers, forcing them to confirm their suppliers' tax compliance status.

This ruling also impacts the relationship between different provisions of the Central Goods and Services Tax Act (CGST Act) and Integrated GST Act (IGST Act), particularly those dealing with eligibility conditions for ITC. It clarifies that the "credit shall not be available" principle applies not just to ineligible goods or services, but to situations where the tax itself has not entered the government's account.

For tax authorities, this judgment strengthens anti-evasion measures and reduces the risk of floating credit (credit claimed without corresponding tax collection) polluting the system. It also provides a clear legal foundation for denying ITC during post-audit assessments when supplier tax deposits are found to be deficient.

Practical Impact

**For Buyers and Recipient Businesses:** Companies can no longer assume that possession of a valid GST invoice automatically entitles them to ITC. They must now conduct due diligence on suppliers' tax filing and payment compliance. Many mid-market and large enterprises are likely to implement supplier verification protocols, requesting GST payment confirmations or GSTR-3B extracts before processing ITC claims. This adds administrative burden and extends payment cycles, as some companies may withhold settlement pending supplier tax deposit verification.

**For CFOs and Finance Teams:** This judgment introduces contingent liability risk. A buyer who claims ITC based on supplier invoices faces retrospective denial if audits reveal the supplier never deposited tax. This could trigger demand notices, interest, and penalties months or years after the transaction. Finance teams must now implement tracking systems to monitor supplier GSTR filings and consider indemnification clauses in purchase contracts shifting risk to suppliers who misrepresent their tax compliance.

**For Compliance and Tax Professionals:** The ruling necessitates revising ITC claim procedures. Firms conducting GST audits and assessments can now confidently recommend or defend ITC denials where supplier tax deposits are missing, without fear of reversal. However, practitioners advising buyers must caution clients that they bear reputational and financial risk if they claim credit on non-compliant suppliers' invoices, even if unaware of non-deposit at the time of claim.

**For Supply Chain and Procurement:** Supppliers who have collected GST but failed to deposit it—whether due to cash flow stress, intentional evasion, or administrative failure—now face a more serious economic consequence: their customers will refuse to pay or will reduce orders due to credit unavailability. This creates downward pressure on non-compliant suppliers and incentivises stronger internal GST compliance.

**For Auditors:** During GST audits, auditors must now verify not only the validity and accuracy of invoices but also the corresponding tax deposits by suppliers. This expands audit scope and justifies sample testing of supplier GSTR-3B filings to corroborate tax payment claims.

The practical effect is a tightening of the entire GST ecosystem, reducing the window for credit fraud but also imposing compliance verification costs on the entire transaction chain.

Key Takeaways

• →ITC is now explicitly conditional on the supplier's actual GST deposit to the government, not merely on invoice validity—buyers cannot claim credit if the supplier failed to remit tax, even with a compliant invoice.
• →Buyers must implement supplier tax compliance verification protocols, including periodic checks of GSTR-3B filings and tax deposit status, to avoid retrospective ITC denial during audit.
• →Finance teams should include indemnification and tax compliance warranties in supplier contracts and establish contingent liability reserves for ITC claims at risk if supplier deposits are later found to be deficient.
• →Audit and compliance functions must expand their GST audit scope to sample-test supplier tax filings and deposits, not just invoice issuance, to defend ITC positions during assessment.
• →Non-compliant suppliers face immediate economic consequences as customers withhold payment or orders pending tax deposit confirmation, creating strong market incentive for GST compliance at every stage of the supply chain.
