Input tax credit (ITC) under GST lets a business reduce its output tax by the GST already paid on purchases, but only when the conditions in Section 16 are met: a valid tax invoice, receipt of the goods or services, tax actually paid to the government, and the return filed. The credit must also appear in your GSTR-2B, some credits are blocked under Section 17(5), and ITC must be claimed by 30 November of the next financial year.
Input Tax Credit (ITC) under GST allows businesses to offset the tax paid on purchases against the tax collected on sales, eliminating the cascading effect of taxes. Understanding eligibility, documentation, and reversal rules is essential to maximising ITC claims and ensuring compliance.
What Is Input Tax Credit Under GST?
Input Tax Credit allows businesses to deduct the tax paid on their purchases from the tax collected on their sales. When a registered dealer acquires goods or services, they pay GST on that purchase. When they sell their own products or services, they collect GST from customers. The core principle involves offsetting the input tax paid against the output tax collected. Only the remaining liability (output tax minus input tax) is remitted to the government.
This mechanism prevents the cascading effect in which tax is charged on a value that already includes previous taxes. ITC ensures that tax is effectively levied only on the value added at each stage of the supply chain.
| Particulars | Amount (Rs.) |
| Tax on final product (output) | 450 |
| Tax paid on raw materials (input) | 300 |
| ITC claimed | 300 |
| Net tax payable to the government | 150 |
Who Is Eligible to Claim ITC?
GST-registered individuals and businesses can claim ITC when all the following conditions are met:
• Possession of a valid tax invoice or debit note issued by the supplier
• The claimant must have received the goods or services
• the recipient must file GSTR-3B within the prescribed deadline
• The supplier must have paid the tax charged to the government
• The recipient must have paid for the invoice within 180 days from the invoice date
• For goods received in instalments, ITC can only be claimed upon receipt of the final lot
• ITC claimed in GSTR-3B must align with details in GSTR-2B, as per CGST Rule 36(4)
• The claimant must not be operating under the composition scheme
Blocked Credits Under Section 17(5)
Section 17(5) of the CGST Act specifies categories where ITC cannot be claimed, even if the purchase is GST-taxable. ITC is available exclusively for business purposes.
| Category | Details |
| Motor Vehicles | Personal use vehicles (exceptions for resale, commercial use, or mandated services) |
| Food & Beverages | Catering, health, and similar services, unless legally required |
| Membership Fees | Club or gym memberships |
| Insurance | Health and life insurance, except when mandated by the government |
| Construction | Costs associated with building immovable property |
| Lost or Destroyed Goods | Items that are damaged, lost, or gifted |
Essential Documents for Claiming ITC
Proper documentation is critical for a valid ITC claim. The following documents are necessary:
• An invoice issued by the supplier of goods or services
• A debit note issued by the supplier to the recipient, if applicable
• A bill of entry for imported goods
• An invoice issued in specific situations, such as under the reverse charge mechanism or for bills under Rs. 200
• An invoice or credit note issued by an Input Service Distributor (ISD) as per GST invoice rules
ITC Rules for Special Scenarios
ITC on Capital Goods: ITC is available for capital goods used for business purposes. However, ITC cannot be claimed for capital goods used solely for manufacturing exempted goods or for personal purposes. No ITC is permitted if depreciation has been claimed on the tax component of capital goods.
ITC on Job Work: A principal manufacturer may send goods to a job worker for further processing. The principal can claim credit for tax paid on goods sent for job work. To avail ITC, the goods must be returned within one year (or three years for capital goods).
ITC from Input Service Distributor (ISD): An ISD is typically a head office or branch that collects ITC on purchases and distributes it to recipient branches under CGST, SGST, IGST, or cess categories.
ITC on Business Transfers: In scenarios such as amalgamations, mergers, or business transfers, any available ITC held by the transferor is transferred to the transferee.
Time Limit for Claiming ITC
ITC must be claimed in GSTR-3B by the earlier of the following two dates:
• 30 November of the financial year immediately following the year in which the invoice or debit note was issued
• The date of filing the annual return (GSTR-9) for that financial year
While 30 November is the ultimate deadline, the GSTR-3B due date for October (typically 20 November) is often the operational deadline. If a taxpayer misses the October filing deadline, they can still claim pending ITC if filed on or before 30 November, albeit with late fees.
When Must ITC Be Reversed?
Several situations require ITC reversal:
• Non-payment of invoices within 180 days requires reversal of the ITC already claimed
• Credit notes issued to ISD by the seller require a corresponding reduced ITC reversal
• Inputs partly used for business and partly for exempted supplies or personal use require proportionate reversal
• Capital goods used partly for business and partly for exempted or personal purposes require proportionate reversal
• Insufficient reversal during the year results in the difference being added to the output tax liability with applicable interest
Details of ITC reversal must be furnished in GSTR-3B.

• ISD: Input Service Distributor, a branch or office that distributes ITC to recipient units
• Cascading Effect: The “tax on tax” scenario that ITC is designed to eliminate

Frequently Asked Questions
Q1: What is the primary objective of ITC under GST?
The main objective is to eliminate the cascading effect of taxes. ITC allows businesses to deduct input tax from output tax, reducing the overall burden at each stage of the supply chain.
Q2: Can a business claim ITC on purchases used for both taxable and exempt supplies?
No. ITC must be proportionately reversed for the portion of inputs or capital goods used for making exempted supplies or for non-business purposes.
Q3: What happens if an invoice is not paid within 180 days?
The ITC already claimed on that invoice must be reversed. The reversed amount is added to the output tax liability along with applicable interest.
Q4: What is the deadline for claiming ITC?
ITC must be claimed by 30 November of the financial year following the year the invoice was issued, or by the date of filing GSTR-9, whichever is earlier.
Q5: Can provisional ITC still be claimed?
No. From 1 January 2022, no provisional ITC can be claimed. Taxpayers can claim only the ITC reflected in their GSTR-2B statement.
