Input tax credit (ITC) allows a GST-registered business to reduce the tax it pays to the government by claiming credit for the GST already paid on business purchases. In practical terms, this means GST is charged only on the value the business adds, which lowers tax costs and protects margins.
A business can claim ITC only when the purchase is used for business purposes, it holds a valid tax invoice, the supplier has filed the relevant GST returns and the invoice appears in GSTR-2B. If these conditions are not met, the credit is denied and the GST paid on purchases becomes a direct cost to the business.
Who can claim ITC
ITC can be claimed by any person registered under the Goods and Services Tax (GST) Act as a regular taxpayer, provided the goods or services are used in the course or furtherance of business.
The following are eligible to claim ITC:
- Manufacturers and traders supplying taxable goods or services
- Service providers whose outward supply is taxable
- Recipients of goods or services used for business purposes
The following cannot claim ITC:
- Composition scheme taxpayers, as they pay tax at a flat rate and cannot claim credit
- Persons whose entire outward supply is exempt from GST
- Non-resident taxable persons, except in respect of goods imported by them
What are the conditions for claiming ITC
All of the following conditions must be satisfied simultaneously under Section 16 of the Central Goods and Services Tax (CGST) Act, 2017:
- Tax invoice or debit note: You must hold a valid tax invoice or debit note issued by a registered supplier.
- Receipt of goods or services: The goods or services must have actually been received. Where goods are delivered in instalments, ITC is available only after receipt of the last instalment.
- Tax paid by the supplier: The supplier must have paid the tax to the government. If the supplier defaults, your ITC may be reversed.
- Invoice reflected in GSTR-2B: The invoice must appear in your GSTR-2B, which is auto-populated from your supplier’s GSTR-1. An invoice not appearing in GSTR-2B cannot be claimed without risk.
- Return filed by you: You must file your own GST returns. ITC cannot be claimed if the relevant return has not been filed.
What is the time limit for claiming ITC?
ITC on an invoice or debit note must be claimed before whichever of the following is earlier:
- 30 November of the financial year following the financial year in which the invoice was issued, or
- The date of filing the annual return for that financial year
For example, ITC on an invoice dated July 2024 must be claimed by 30 November 2025 or the date of filing the annual return for FY 2024-25, whichever is earlier. If the credit is not claimed within this period, it is permanently lost.
Blocked credits: What you cannot claim
Section 17(5) of the CGST Act, 2017 lists specific goods and services on which ITC is not available, even if all other conditions for claiming credit are satisfied.
These include:

What is the eligibility for ITC on imports?
GST paid as Integrated Goods and Services Tax (IGST) at the time of import is eligible for ITC. The bill of entry serves as the tax document for claiming this credit.
The credit is available only after the imported goods have been received and recorded in the books of account, and the applicable customs duties and IGST have been paid.
When ITC must be reversed
ITC must be reversed in the following situations:
- Supplier default: If the supplier does not pay the GST due to the government, your ITC may be reversed proportionately.
- Non-payment to supplier within 180 days: If you do not pay your supplier within 180 days from the invoice date, the ITC must be reversed. Once payment is made, the credit can be re-claimed.
- Use for exempt supply or personal purposes: If goods or services on which ITC has been claimed are later used for exempt supplies or personal use, the credit must be reversed.
- Capital goods partly used for non-business purposes: Where capital goods are used partly for non-business purposes, ITC must be reversed proportionately.
Conclusion
ITC reduces GST cost only when every condition is met; eligibility, documentation, supplier compliance and timing all matter. Missing even one requirement can mean loss of credit, along with interest and penalties where reversal applies.
Businesses should verify supplier filings, reconcile purchase invoices with GSTR-2B and identify blocked or reversible credits before claiming ITC. This is where disciplined monthly reconciliation makes the biggest difference.
