Input tax credit (ITC) is the credit that a registered person under GST receives for the tax paid on inputs (goods and services) used in the course or furtherance of business, which can be set off against the output tax liability on supplies made. Under Indian law, the right to claim ITC is governed by Section 16 of the Central Goods and Services Tax Act, 2017, subject to conditions including possession of a valid tax invoice, receipt of goods or services, filing of returns, and the supplier having deposited the tax with the government.
Legal definition
The CGST Act, 2017 establishes the framework for input tax credit:
Section 16(1): "Every registered person shall, subject to such conditions and restrictions as may be prescribed and in the manner specified in section 49, be entitled to take credit of input tax charged on any supply of goods or services or both to him which are used or intended to be used in the course or furtherance of his business..."
Section 16(2): Prescribes four conditions for availing ITC: (a) possession of a tax invoice or debit note issued by a supplier; (b) receipt of the goods or services; (c) the tax charged has been actually paid to the Government by the supplier; and (d) the registered person has furnished the return under Section 39.
Section 16(4): Imposes a time limit — ITC in respect of any invoice or debit note shall be availed by the registered person by the thirtieth day of November following the end of the financial year to which such invoice pertains.
Section 17(5): Lists "blocked credits" — input tax credit is not available on motor vehicles (with exceptions), food and beverages, outdoor catering, beauty treatment, health services, club memberships, rent-a-cab, life insurance, travel benefits, and goods or services used for personal consumption.
How courts have interpreted this term
Union of India v. VKC Footsteps India Pvt. Ltd. [(2022) 2 SCC 603]
The Supreme Court examined ITC refunds under the inverted duty structure (where the tax on inputs is higher than the tax on the output). The Court upheld the validity of Rule 89(5) of the CGST Rules, which restricts refund calculations to ITC on inputs only, excluding input services. The bench also applied a "functionality test" to interpret the term "plant" under Section 17(5), holding that the term must be given a broad interpretation based on whether the item performs a function in the business.
Chief Commissioner of CGST v. Safari Retreats Pvt. Ltd. [(2024) SCC OnLine SC 3260]
The Supreme Court held that the construction of commercial buildings intended for letting out on rent is not "construction of immovable property on own account" within the meaning of Section 17(5)(d), and therefore ITC on such construction is not blocked. This landmark ruling expanded the scope of ITC eligibility for real estate developers constructing commercial properties for rental purposes.
Types of input tax credit
ITC can be categorised based on the nature of inputs:
- ITC on inputs: Credit for tax paid on raw materials, consumables, and goods used in manufacturing or provision of services
- ITC on input services: Credit for tax paid on services used in the course of business (such as professional fees, rent, insurance, transportation)
- ITC on capital goods: Credit for tax paid on capital goods (plant, machinery, equipment) used in business — available in full in the year of purchase
- ITC under reverse charge: The recipient who pays GST under reverse charge mechanism is entitled to ITC on such payment, subject to Section 16 conditions
Why this matters
Input tax credit is the central mechanism of the GST framework that eliminates the cascading effect of "tax on tax" that existed under the pre-GST regime. By allowing businesses to offset the tax paid on inputs against the tax collected on outputs, ITC ensures that tax is effectively levied only on the value addition at each stage of the supply chain.
For businesses, ITC directly impacts profitability. Failure to claim eligible ITC within the prescribed time limit (30 November of the following financial year under Section 16(4)) results in a permanent loss of credit. The conditions under Section 16(2) — particularly the requirement that the supplier must have deposited the tax — create a situation where the buyer's ITC depends on the seller's compliance, leading to significant compliance verification burdens.
For practitioners, the blocked credits under Section 17(5) are the most litigated area of ITC law. The Safari Retreats ruling significantly expanded ITC eligibility for the real estate sector. Other frequent disputes involve the proportional reversal of ITC under Section 17(1)-(2) for exempt supplies, the determination of "used in the course or furtherance of business," and the interpretation of capital goods versus inputs for refund purposes.

Frequently asked questions
What are the conditions for claiming ITC under GST?
Under Section 16(2) of the CGST Act, four conditions must be met: (a) the registered person must possess a valid tax invoice or debit note, (b) they must have received the goods or services, (c) the tax must have been actually paid to the government by the supplier, and (d) the registered person must have filed their return under Section 39. Additionally, the ITC must be claimed before 30 November of the following financial year.
What is blocked credit under GST?
Section 17(5) of the CGST Act lists goods and services on which ITC is not available, including motor vehicles (with exceptions for specified businesses), food and beverages, outdoor catering, beauty treatment, health services, club memberships, rent-a-cab services, life insurance, travel benefits, and goods or services used for personal consumption. These are called "blocked credits."
Can ITC be claimed on construction of buildings?
ITC is generally blocked on "works contract services for construction of an immovable property" under Section 17(5)(c) and on "construction of immovable property on own account" under Section 17(5)(d). However, the Supreme Court in Safari Retreats (2024) held that construction of buildings intended for letting out on rent does not fall within the blocked category, expanding ITC eligibility for commercial property developers.
