Input Tax Credit Under GST

Input Tax Credit (ITC) is a crucial mechanism under the GST regime that allows businesses to reduce their tax liability by claiming credit for GST paid on purchases used in the course of business. However, ITC eligibility under GST has shifted from being invoice-centric to being driven by statutory compliance and portal-based validation.

This comprehensive guide covers the eligibility framework, conditions under Section 16, time limits, and practical compliance requirements for claiming ITC.

Section 16(1): The Substantive Entitlement

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 buyer must possess a valid tax invoice or debit note issued by a registered supplier.

Practical pressure point: Document must be a valid GST document, not a proforma or quotation.

Condition 2: Invoice Matching — Section 16(2)(aa)

The supplier must furnish the invoice in GSTR-1/IFF and it must be communicated to the recipient.

Practical pressure point: The invoice must reflect in GSTR-2B — the single most common point of failure.

Condition 3: ITC Not Blocked — Section 16(2)(ba)

The credit is not restricted under Section 38. This is now the IMS gateway.

Practical pressure point: From 1 April 2026, IMS determines ITC eligibility based on recipient actions such as accepting, rejecting, or keeping invoices pending, with inaction deemed acceptance.

Condition 4: Receipt of Goods or Services — Section 16(2)(b)

The buyer must have received the goods or services.

Deemed Receipt: A buyer is deemed to have received goods/services in the following cases:

The supplier delivers goods to a third party on the buyer's instructions
The supplier provides services to another person on behalf of the buyer

Condition 5: Tax Paid to Government — Section 16(2)(c)

The tax charged on the supply must be actually paid to the government by the supplier.

Practical pressure point: Tax must be paid either in cash or through utilized ITC.

Condition 6: Return Filing — Section 16(2)(d)

The buyer must have filed the relevant GST return under Section 39.

Special Situations Under Section 16(2)

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

Section 17(5) of the CGST Act specifies certain "blocked credits" on which ITC cannot be claimed, even if the expenditure is incurred for business purposes. These include:

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
