Since the dawn of GST (Goods and Services Tax) in India, Input Tax Credit has been a concern of extensive debate. Seldom do we see a topic that generates as much discussion as ITC (Input Tax Credit).
The main concerns revolve around the availment of ITC in GST is whether it is a fundamental or vested right of a person or is merely a concession/ benefit that one is entitled to receive.
In this article, we delve into the intricacies of this ongoing debate, examining different legal perspectives and shedding light on the significance of ITC in today’s complex business landscape.
The Confusion Surrounding Input Tax Credit Rights
- Many presume that claiming ITC (Input Tax Credit) is their vested right, vested here, meaning that one will receive the claim without any legislative conditions and terms attached.
- There is another conundrum surrounding ITC in GST being assumed as a definite benefit. These disputes have led to numerous pending litigations in the Honourable Courts.
Is Input Tax Credit a Vested Right?
To answer directly — No, not at the outset.
A vested right is a fixed and absolute right, enforceable without conditions. ITC does not satisfy this definition at the time of procurement.
Under GST law, Section 16 of the CGST Act, 2017 governs eligibility and conditions.
| Condition | Requirement |
|---|---|
| Registration | Must be a registered person |
| Supply | Goods/services must be received |
| Usage | Used in the course of business |
| Documentation | Valid tax invoice/debit note |
| Supplier Compliance | Tax must be paid to the government |
| Filing | GST returns must be filed |
| Matching | Invoice must be reflected in GSTR-2B |
Further, Sections 16(2), 16(3), 16(4), 17 and 18 impose additional restrictions.
If these conditions are not fulfilled, ITC cannot be availed.
Thus, ITC is inchoate in nature — it exists in a preliminary stage until all conditions are satisfied.
Once these conditions are fulfilled, ITC transforms into a vested right ITC under GST, becoming enforceable.
Evolution of Section 16 Framework in 2026
The compliance framework under Section 16 has significantly evolved:
- Section 16(2)(aa) mandates invoice reflection in GSTR-2B
- Section 16(4) enforces strict time limits
- Section 16(5) provides retrospective relief for FY 2017–2021
This demonstrates that ITC eligibility GST is now system-driven, reducing manual discretion.
Adapting to the Evolving Section 16 Framework in 2026?
With stricter GSTR-2B matching, time-limit restrictions, and system-driven validations, ITC compliance under Section 16 now demands real-time accuracy and automation.
Transitional Nature of Input Tax Credit and Law Attached
ITC in GST is of transitional nature, which means a person can claim ITC at the afore-set Input Tax Credit rate on the purchase of stocks lying with him transfer the tax to other parties in supply chain. But to claim this ITC, the credit must be claimed within a limited period, and the amount must be credited to his Electronic Credit Ledger under the GST.
But if there is a delay in filing the credit amount, will the credit be disregarded?
To resolve such scenarios, a considerable judgment was passed in Hon’ble Gujarat High Court in M/s. Siddharth Enterprises vs The Nodal Officer, TS-684-HC-2019(GUJ)-NT which stated –
“The entitlement of credit of eligible duties on the purchases made in the pre-GST regime as per the then existing CENVAT credit rules is a vested right and, therefore, it cannot be taken away by virtue of Rule 117 of the Central GST Rules, 2017, with retrospective effect for failure to file the form GST Tran-1 within the due date, i.e. 27.12.2017. The provision for the facility of Input Tax Credit is as good as the tax paid till the tax is adjusted, and, therefore, the right to the credit had become absolute under the Central Excise Act; therefore, the credit is indefeasible, and the same cannot be taken away.”
Judicial Position Strengthened
Recent rulings (2025–2026) have clarified:
- ITC cannot be denied for clerical errors without revenue loss.
- Buyers may be protected against supplier default in genuine transactions.
- ITC can be used for pre-deposit in appeals.
However, courts continue to deny relief in cases involving fraud or non-compliance.
Is Input Tax Credit a Fundamental Right?
Law says Input Tax Credit is not a fundamental right but a constitutional right under Article 300A of the Indian Constitution. Once the prerequisite conditions are complied with, ITC in GST becomes a vested right, and the person claiming the right is protected under the constitutional law in case of any disputes or grievances.
In fact, once the right becomes absolute, the Constitution gives a right of property to every citizen under the law.
Is Input Tax Credit Just a Concession or a Benefit?
Contrary to the aforementioned arguments, some argue that ITC is merely a concession granted by the tax authorities. This viewpoint posits that tax laws and regulations provide for ITC as a means to incentivize compliance and encourage businesses to maintain proper documentation and reporting.
According to this perspective, ITC in GST is contingent upon fulfilling certain conditions and is subject to the discretion of the tax authorities.
This is well established by the following case judgments passed by the Honourable Courts –
The Supreme Court, in the case of Ald Automotive – 2018-TIOL-385-SC-VAT, held that input credit is in nature of benefit/ concession extended to dealers under the statutory scheme.
In the Nelco case – 2020-TIOL-641-HC-MUM-GST, the Bombay High Court held that availing of input tax credit under section 140(1) is a concession attached with conditions of its exercise within the time limit.
The Apex Court in the case of M/S. TVS Motor Company Ltd. vs. The State of Tamil Nadu And Others, 2018 Latest Caselaw 763 SC, read as under:
“After discussing certain judgments of this Court and other High Courts, the High Court has observed that the legal position was that the right to claim ITC is not a vested right or an indefeasible right. It is a benefit conferred under the Act in certain contingencies and subject to conditions prescribed in the statutory scheme. Therefore, it is open to the State Legislature to provide for conditions and restrictions while extending the concession. Likewise, it was also necessary for any assessee to claim input credit to fulfil those conditions.”
Three-Stage Legal Position of ITC
Modern interpretation recognises ITC as a three-stage construct:
| Stage | Nature | Position |
|---|---|---|
| Stage 1 | Concession | Conditions not met |
| Stage 2 | Inchoate Right | Partial compliance |
| Stage 3 | Vested Right of ITC under GST | Fully compliant |
This framework is crucial for litigation strategy and compliance planning.
ITC Set Off Rules 2026 Changes
Recent changes have refined utilisation rules:
- ITC must be utilised in prescribed order (IGST first)
- Increased system validation
- Restrictions on cross-utilisation
These changes directly affect working capital optimisation.
ITC Reversal Rule 37
Rule 37 requires reversal of ITC if payment to supplier is not made within 180 days.
Practical implications:
- Continuous vendor tracking required
