Section 16 of the CGST Act is the foundation of Input Tax Credit (ITC) under GST. It establishes both the substantive right to claim ITC and the conditions that must be satisfied before credit can be taken. Understanding these conditions is essential for every GST taxpayer.
This comprehensive guide explains each condition for claiming ITC under Section 16 in detail.
Section 16(1): The Substantive Right
Section 16(1) of the CGST Act grants every registered person the right to take credit of input tax charged on any supply of goods or services, or both, that are used or intended to be used in the course or furtherance of business.
Three threshold requirements:
- The claimant must be registered (a person under the composition scheme of Section 10 is excluded)
- The input tax must have been charged on an inward supply
- The supply must carry a business nexus
Section 16(2): The Cumulative Conditions
Section 16(2) opens with a non-obstante clause, which means its conditions override the general entitlement in sub-section (1). All of them must be satisfied; credit fails if any single condition is unmet.
Condition 1: Possession of Tax Document — Section 16(2)(a)
The Requirement: The buyer must possess a valid tax invoice or debit note issued by a registered supplier.
Practical Points:
- Document must be a valid GST document
- Proforma invoices or quotations do not qualify
- The invoice must be issued by a registered supplier
Condition 2: Invoice Matching — Section 16(2)(aa)
The Requirement: The supplier must furnish the invoice in GSTR-1/IFF and it must be communicated to the recipient.
Practical Points:
- The invoice must reflect in GSTR-2B
- This is the single most common point of failure
- If the supplier has not filed GSTR-1, ITC cannot be claimed
Condition 3: ITC Not Blocked — Section 16(2)(ba)
The Requirement: The credit is not restricted under Section 38.
Practical Points:
- This is now the IMS gateway
- From 1 April 2026, IMS determines ITC eligibility based on recipient actions
- Inaction on IMS is deemed acceptance
Condition 4: Receipt of Goods or Services — Section 16(2)(b)
The Requirement: The buyer must have received the goods or services.
Deemed Receipt:
- Supplier delivers goods to a third party on the buyer's instructions
- Supplier provides services to another person on behalf of the buyer
Multiple Lots:
- If goods are received in installments, ITC can only be claimed after the last lot or installment is received
Condition 5: Tax Paid to Government — Section 16(2)(c)
The Requirement: The tax charged on the supply must be actually paid to the government by the supplier.
Practical Points:
- Tax must be paid either in cash or through utilized ITC
- If the supplier does not pay tax, the buyer's ITC is at risk
- Courts have held that a legitimate purchaser who meets all conditions will not have ITC denied simply because the supplier did not pay tax
Condition 6: Return Filing — Section 16(2)(d)
The Requirement: The buyer must have filed the relevant GST return under Section 39.
Practical Points:
- ITC claimed in a GSTR-3B can only be taken if that GSTR-3B has been filed
- Filing of return is a cumulative condition—it must be satisfied
Provisos to Section 16(2): Special Situations
Proviso 1: Multiple Lots
If goods are received in installments against a single invoice, ITC can only be claimed after the last lot or installment is received.
Proviso 2: Non-Payment to Supplier Within 180 Days
If the buyer fails to pay the supplier (value + tax) within 180 days from the invoice date:
- ITC must be reversed along with interest under Section 50
Proviso 3: Reclaiming ITC
Once payment is made to the supplier, the reversed ITC can be reclaimed.
Section 16(3): ITC Restriction for Depreciated Assets
If a taxpayer claims depreciation on the GST component of capital goods under the Income Tax Act, ITC cannot be claimed on that component under GST.
Section 16(4): Time Limit to Claim ITC
A registered person cannot claim ITC:
- After 30th November following the end of the financial year to which the invoice pertains, OR
- After filing the annual return for that year, whichever is earlier.
Section 17(5): Blocked Credits
Even if all Section 16(2) conditions are met, ITC cannot be claimed if the credit is blocked under Section 17(5).
Common Blocked Credits:
- Motor vehicles (with seating capacity ≤13 persons) unless used for specified purposes
- Construction of immovable property
- Employee-related expenses
- Food and beverages, outdoor catering, beauty treatments, health services, club memberships
