Input Tax Credit is the backbone of GST — it's what prevents the 'tax on tax' problem and keeps the overall tax burden proportionate to actual value addition. Understanding exactly what you can and can't claim as ITC is one of the most important — and most commonly mishandled — aspects of GST compliance.

What is ITC?

ITC is the credit a GST-registered business gets for the GST it has already paid on purchases of goods or services (called 'inputs', 'input services', or 'capital goods') used or intended to be used in the course or furtherance of business. This credit accumulates in the Electronic Credit Ledger and can be used to offset the GST liability on outward supplies (sales), reducing the amount that must actually be paid in cash.

Conditions to Claim ITC (Section 16)

•      You must possess a valid tax invoice, debit note, or other prescribed document from the supplier

•      You must have actually received the goods or services (in case of goods received in instalments, credit is available only after receipt of the last instalment)

•      The tax charged on the supply must have actually been paid to the government by the supplier

•      You must have filed the relevant GST return

•      The invoice details must be reflected in your GSTR-2B (the auto-drafted static ITC statement generated from your suppliers' filings)

•      Where payment for the invoice (including the tax component) is not made to the supplier within 180 days of the invoice date, the ITC already claimed must be reversed along with interest — it can be reclaimed once the payment is actually made

Blocked Credits (Section 17(5))

Certain purchases never qualify for ITC, even when genuinely used for business, because the law specifically blocks them:

•      Motor vehicles for transport of persons with seating capacity up to 13 (including the driver), except when used for further supply of such vehicles, transportation of passengers, or driving training — ITC on trucks/goods vehicles used for business is generally allowed

•      Food and beverages, outdoor catering, beauty treatment, health services, cosmetic and plastic surgery — unless the inward supply is used to make an outward supply of the same category, or is obligatory for an employer to provide to employees under any law

•      Membership of a club, health and fitness centre

•      Life insurance and health insurance, unless obligatory under law, or used to make a further outward taxable supply of the same category

•      Works contract services for construction of an immovable property (other than plant and machinery), except where it is an input service for further supply of works contract service

•      Goods or services received for construction of an immovable property on own account (other than plant and machinery), even if used in the course of business

•      Goods lost, stolen, destroyed, written off, or disposed of by way of gift or free samples

•      Tax paid as a result of detention, seizure, confiscation, fraud, wilful misstatement, or suppression of facts

•      Tax paid under the Composition Scheme by the recipient (not applicable in the usual sense, since composition dealers themselves can't claim ITC)

Special ITC Situations

•      ITC on capital goods: allowed in full in the year of purchase (subject to the goods being used for taxable supplies), but must be reversed proportionately if the capital goods are later used for exempt supplies or non-business purposes

•      Common credit for taxable and exempt supplies: where inputs/input services are used partly for taxable and partly for exempt supplies, ITC must be proportionately apportioned under Rule 42/43

•      ITC on capital goods sold before the end of useful life: requires reversal of a proportionate amount, or payment of tax on the transaction value, whichever is higher

Frequently Asked Questions

Q1. Can I claim ITC on any business purchase?

A. No — only on purchases used for business and not covered under the 'blocked credit' list in Section 17(5).

Q2. What happens if my supplier doesn't pay the tax they collected from me?

A. Under current rules, your ITC is largely determined by what appears in your GSTR-2B, so if the supplier fails to file/report correctly, your credit may not be reflected, and any credit already claimed against a non-compliant supplier may need to be reversed.

Q3. Is there a time limit to claim ITC for a financial year?

A. Yes, ITC for invoices of a financial year must generally be claimed by 30th November following the end of that financial year, or the date of filing the annual return, whichever is earlier.

Q4. Can ITC be claimed on capital goods purchased for the business?

A. Yes, in full in the year of purchase if used for making taxable supplies, though it must be reversed proportionately if the asset is later diverted to exempt supplies or personal use, or sold before the end of its useful life.

Q5. What is the 180-day rule for ITC?

A. If you don't pay your supplier (including the GST component) within 180 days of the invoice date, any ITC already claimed on that invoice must be reversed with interest; it can be reclaimed once the payment is subsequently made.

Q6. Can I claim ITC on goods given as free samples or gifts?

A. No, ITC on inputs used to make goods that are subsequently given away as free samples or gifts is specifically blocked under Section 17(5).
