Under India’s central GST framework, a registered person can generally claim input tax credit (ITC) on goods or services used or intended for use in the course or furtherance of business—but only when the statutory conditions, restrictions and deadline are met. A GST-bearing invoice alone does not make a purchase eligible: business use, receipt, documentation, tax and return requirements, apportionment rules and blocked-credit provisions all matter.
Who can claim input tax credit under GST?
Section 16(1) of the Central Goods and Services Tax Act gives a registered person the general entitlement to credit input tax on supplies “used or intended to be used in the course or furtherance of his business,” subject to conditions and restrictions. Read the CGST Act, Chapter V alongside section 17: a purchase may relate to business and still be partly restricted or specifically blocked.
This is a general guide to central Indian GST rules, not a determination about a particular invoice. The result can depend on the transaction, the recipient’s registration, the use of the purchase, the relevant tax period and any applicable exception. Check the rules applying to the particular supply and registration before taking credit.
A practical sequence for reviewing a purchase

#1 Best Overall
- Confirm the recipient is registered and is the person entitled to the credit.
- Identify the use: determine whether the goods or services are used or intended for business, and whether they also support non-business or exempt supplies.
- Check for a section 17(5) block and any exception that may apply.
- Verify the prescribed document and receipt of the goods or services.
- Check the tax, return and supplier-payment conditions applicable to the claim.
- Confirm the time limit for the invoice or debit note and retain evidence supporting the claim.
What conditions must be met for an ITC claim?
Section 16(2) sets out conditions that work together. Treat each invoice or debit note as a claim to verify, rather than assuming that meeting one condition settles eligibility.
- Prescribed evidence: hold a tax invoice, debit note or another document prescribed for the type of supply.
- Receipt: the recipient must have received the goods or services. In specified circumstances, goods delivered to another person on the registered recipient’s direction count as received by that recipient.
- Tax paid to government: the tax charged on the supply must have been paid to the government, subject to the statutory framework.
- Return furnished: the recipient must furnish the return required under section 39.
Special cases that affect when or how much credit is available
- Goods received in lots or instalments: where an invoice covers goods received in lots or instalments, credit is available on receipt of the last lot or instalment.
- Supplier not paid within 180 days: if the recipient does not pay the supplier the value of the supply plus tax within 180 days of the invoice date, the prescribed amount of ITC must be added to output tax liability with applicable interest. The recipient may avail the credit again after paying the supplier. See the CBIC Input Tax Credit Rules for the reversal procedure.
- Depreciation claimed on tax: ITC cannot be claimed on the tax component of capital goods if depreciation has been claimed on that same tax component under income-tax law.
Which GST credits are reduced by apportionment?
Apportionment is different from a categorical blocked credit. Under section 17(1)–(2), credit is restricted to the portion attributable to business use when a supply is used for both business and non-business purposes. Where inputs support both taxable supplies—including zero-rated supplies—and exempt supplies, only the portion attributable to taxable supplies is generally available. The calculation follows prescribed methods; it is not simply an all-or-nothing choice based on whether the business has any taxable sales.
For a shared expense, identify its actual use and the outputs it supports, then apply the prescribed allocation method. Do not treat a purchase as fully creditable merely because it is recorded as a business expense.
Which ITC is blocked under section 17(5)?
Section 17(5) blocks credit for named categories, but several categories have exceptions. The table is a practical map, not a complete statement of every statutory definition or exception. Review the Act’s section 17 for the precise wording and facts of a transaction.
| Category | General treatment and material qualifications |
|---|---|
| Motor vehicles and other conveyances | Generally blocked, with exceptions that include use for further taxable supply, passenger transport, driver or operator training, and transportation of goods. |
| Food, beverages and certain personal services | Food and beverages, outdoor catering, beauty treatment, health services, and cosmetic or plastic surgery are generally blocked. Exceptions include making a taxable outward supply of the same category, or supplying them as part of a taxable composite or mixed supply. |
| Memberships and travel benefits | Club, health and fitness-centre membership is generally blocked. Employee vacation benefits such as leave or home travel concession are also blocked. |
| Rent-a-cab, life insurance and health insurance | Generally blocked, subject to specified exceptions, including certain benefits an employer is legally obliged to provide and certain same-category taxable outward supplies. |
| Works contracts and construction of immovable property | Specified works-contract services for construction, and goods or services used to construct immovable property on one’s own account, are generally blocked, subject to the Act’s rules for plant and machinery and further works-contract supplies. |
| Other specified supplies and circumstances | Credit is blocked for goods or services on which tax has been paid under the composition scheme; supplies received by a non-resident taxable person except imported goods; personal-consumption supplies; goods lost, stolen, destroyed, written off, gifted or given as free samples; and specified taxes paid under sections 74, 129 and 130. |
Why construction and vehicles need closer review
The construction rule is not a blanket ban on every cost connected with a building, nor does the phrase “plant and machinery” make every machine creditable. The statutory explanation covers reconstruction, renovation, additions, alterations and repairs to the extent capitalized. The Act’s plant-and-machinery definition has inclusions and exclusions, and the works-contract rule has its own limits. Apply the exact statutory definitions to the asset and transaction before claiming credit.
For a vehicle or another listed category, test the statutory category and the actual use against the relevant exception. A general assertion that an item is used “for business” does not by itself establish that a blocked-credit exception applies.

The applicable document depends on the supply. The CBIC ITC rules recognize a supplier’s invoice under section 31, a debit note under section 34, a bill of entry or similar prescribed customs document for import IGST, and specified Input Service Distributor (ISD) invoices or credit notes.
Tax-invoice checklist
For a standard tax invoice, CBIC’s invoice rules list particulars that include:
- supplier name, address and GSTIN;
- a unique serial number and issue date;
- recipient details;
- HSN code or service accounting code, as applicable;
- description and, where relevant, quantity;
- total value, taxable value, tax rate and tax amount;
- place of supply for an inter-State supply and delivery address if different; and
- whether tax is payable on a reverse-charge basis, plus the supplier’s signature or digital signature.
Invoice requirements have special cases and notified variations, so use this as a practical check rather than an exhaustive checklist for every document type. Reporting and return procedures can change; verify the requirements for the relevant tax period instead of relying on old portal labels or workflows.

Build a supportable record trail
As practical recordkeeping, reconcile the purchase register with supplier-reported invoice information and the return statements relevant to the period. Keep evidence of receipt and business use, as well as payment evidence. These steps support the statutory conditions; they are not a substitute for the prescribed tax document or a complete list of every document that may be required.
CBIC’s accounts and records rules address preservation of accounts and associated invoices, bills of supply, credit and debit notes, and delivery challans, and require records to be kept at each related place of business and produced on demand. The applicable retention period should be checked against the current section 36 and amendments; no fixed number of years is stated here.
Input services shared across state registrations
Where consolidated input services are directly used by GST registrations in more than one state, CBIC’s Sectoral FAQs describe invoicing or distribution through the ISD mechanism to the distinct persons that actually used the services. ISD requirements have evolved, so confirm the registration and distribution rules applying to the relevant tax period before following a filing procedure.

What is the time limit for claiming ITC?
CBIC Circular 237/31/2024-GST, dated 15 October 2024, states the general section 16(4) deadline as 30 November following the end of the financial year to which the invoice or debit note pertains, or the date the relevant annual return is furnished, whichever is earlier. Apply the earlier of those dates to the claim. The CBIC circular is important because the CBIC Act webpage’s displayed section 16(4) wording refers to an earlier September-return formulation.
The same circular discusses retrospective relief introduced by the Finance (No. 2) Act, 2024 through sections 16(5) and 16(6) for specified cases. That is limited, fact-dependent relief—not a general extension for every late ITC claim. Check whether the particular tax period and circumstances fall within those subsections before relying on it.
