Input Tax Credit (ITC) is the mechanism that makes GST a value-added tax — each business in the supply chain claims credit for the tax paid on inputs, and only pays GST on the value they add. In theory, it is elegant. In practice, ITC is the single most contested area of GST law, with thousands of crores locked in disputes across India.
This guide gives you a complete, practical understanding of ITC — what you can claim, what you cannot, and how to protect your credits.
Who Can Claim ITC?
Any registered GST taxpayer who makes taxable outward supplies (goods or services) can claim ITC on inward supplies used in the course or furtherance of business. Four conditions must be met simultaneously:
Condition 1: You must hold a valid tax invoice or debit note from a registered supplier.
Condition 2: You must have received the goods or services (or both).
Condition 3: The tax charged on that supply must have been actually paid to the government by your supplier — Section 16(2)(c). This is the most litigated condition.
Condition 4: You must have filed your GST return.
Blocked Credits — Section 17(5): What You CANNOT Claim
Section 17(5) is the most important blocking provision in GST. ITC is specifically blocked on the following categories regardless of business use:
Motor vehicles: ITC blocked on purchase of motor vehicles for transportation of persons (up to 13 seats) — except for dealers, rental companies, and transportation service providers. ITC on commercial vehicles (trucks, buses above 13 seats) is allowed.
Food and beverages: ITC blocked on food, beverages, outdoor catering, health services, cosmetics, beauty treatment — unless you are in the business of supplying these services.
Club memberships and health clubs: ITC on club fees, gym memberships, spa — completely blocked.
Travel benefits to employees: ITC on leave travel, home travel concession benefits given to employees — blocked.
Works contract for immovable property: ITC on works contract services for construction of immovable property — blocked (except for plant and machinery).
Construction of immovable property: ITC on goods or services used for construction of immovable property on own account — blocked.
Composition dealers: Composition scheme taxpayers cannot claim ITC at all.
Residential rent (post July 2022): ITC on GST paid under RCM on residential rent for employee accommodation — specifically blocked under personal consumption rule.
GSTR-2B — The New ITC Control Document
From FY 2022-23, ITC can only be claimed to the extent it appears in your GSTR-2B. GSTR-2B is an auto-populated document generated from your suppliers' GSTR-1 filings. It shows exactly what ITC is available to you for each tax period.
Rule 36(4): ITC in excess of what appears in GSTR-2B cannot be claimed. Any ITC claimed beyond GSTR-2B is liable to reversal with 18% interest.
GSTR-2B vs GSTR-3B reconciliation: Every month before filing GSTR-3B, compare your purchase register with GSTR-2B. ITC not in GSTR-2B either means your supplier hasn't filed GSTR-1 (follow up) or the invoice details don't match (correct with supplier).
Proportionate ITC Reversal — Rules 42 & 43
Rule 42 — Inputs and input services: If you use inputs or input services for both taxable and exempt supplies, ITC must be reversed proportionately. Formula: ITC reversal = (Exempt turnover / Total turnover) × Total ITC.
Rule 43 — Capital goods: Capital goods used for both taxable and exempt supplies require monthly reversal of ITC over 60 months (5 years) in proportion to exempt use.
This is particularly relevant for banks, insurance companies, real estate developers, and any business with a mix of taxable and exempt supplies.
ITC on Capital Goods
ITC on capital goods is fully available in the year of purchase (unlike the earlier VAT regime which required spreading). The full ITC can be claimed in the GSTR-3B of the month in which the goods are received. However, if the capital goods are later sold, a portion of ITC must be reversed based on residual life.
ITC Reversal on Non-Payment to Supplier Within 180 Days
Under Section 16(2), if you fail to pay your supplier within 180 days of the date of invoice, the ITC claimed must be reversed (added back to output tax liability) along with applicable interest. When you eventually pay the supplier, you can re-claim the ITC.
This is a compliance trap that catches many businesses — especially those with extended credit terms from suppliers. Track your creditor aging report specifically for this purpose.
Transitional ITC — Carry Forward from Old Regime
For any remaining disputes on transitional credits (pre-GST VAT/service tax credits carried forward in TRAN-1/TRAN-2), the Supreme Court has held that taxpayers have a right to carry forward legitimate credits. If you have unresolved TRAN-1 disputes, consult a GST expert — the window for corrections has been extended multiple times.
