GST Input Tax Credit: Conditions Under Section 16 of CGST Act

Claiming Input Tax Credit under GST is not automatic. Section 16 of the CGST Act lays down specific conditions that must be satisfied.

MANDATORY CONDITIONS UNDER SECTION 16(2)

1. Possession of tax invoice or debit note: You must hold a valid tax invoice, debit note, or other prescribed tax-paying document issued by the supplier. (Section 16(2)(a))

2. Goods or services received: The goods or services must have been actually received by you. For goods delivered in lots, ITC is available only on receipt of the last lot. (Section 16(2)(b))

3. Tax paid to government: The supplier must have actually paid the tax charged on the invoice to the government. (Section 16(2)(c))

4. Return filed: You must have filed your GSTR-3B return for the relevant period. (Section 16(2)(d))

5. ITC reflected in GSTR-2B: The details of the invoice must appear in your auto-generated GSTR-2B statement. (Section 16(2)(aa))

6. Payment within 180 days: If you do not pay the supplier within 180 days from the date of the invoice, the ITC already claimed must be reversed along with interest. It can be re-claimed once payment is made. (Proviso to Section 16(2))

TIME LIMIT TO CLAIM ITC — SECTION 16(4)
ITC for any invoice must be claimed by the earlier of:
- The 30th of November following the end of the financial year to which the invoice pertains, or
- The date of filing the annual return (GSTR-9) for that financial year

For example, ITC on an invoice dated 15 January 2026 must be claimed by 30 November 2026 or the GSTR-9 filing date for FY 2025-26, whichever is earlier.

SECTION 16(5) — EXTENDED TIME FOR CERTAIN CASES
Inserted by Finance Act (No. 2), 2024 with retrospective effect from 1 July 2017, this helps taxpayers whose ITC was denied solely because they missed the Section 16(4) deadline for FY 2017-18 to 2020-21. Such ITC could be claimed in returns filed up to 30 November 2021.

PRACTICAL TIP
Reconcile your purchase register with GSTR-2B every month before filing GSTR-3B. Any invoice missing from GSTR-2B should be flagged with the supplier immediately. Do not claim ITC that is not in GSTR-2B.
