Section 16 of the CGST Act, 2017 – Eligibility and Conditions for Input Tax Credit (ITC)

Layman Meaning

Section 16 is the heart of the GST credit mechanism. It allows a registered person to claim credit of GST paid on purchases and expenses used in the course or furtherance of business.

Simple Formula:

Purchase GST (Input Tax) can be adjusted against Sales GST (Output Tax).

Basic Eligibility for ITC [Section 16(1)]

A registered person can claim ITC on:

✅ Goods purchased for business

✅ Services received for business

✅ Capital goods used for business

❌ Goods/services used for personal purposes

❌ Goods/services used for exempt supplies (subject to specific rules)

Four Mandatory Conditions for Claiming ITC [Section 16(2)]

All four conditions must be satisfied:

1. Possession of Tax Invoice or Prescribed Document

The recipient must have:

• Tax Invoice
• Debit Note
• Bill of Entry
• Other prescribed document

2. Receipt of Goods or Services

The goods or services must actually be received.

3. Tax Paid to Government

The supplier must have paid the tax to the Government.

4. Return Filed

The recipient must have filed the GST return (GSTR-3B).

Easy Memory Trick

"I-R-T-R"

• I = Invoice Available
• R = Receipt of Goods/Services
• T = Tax Paid by Supplier
• R = Return Filed by Recipient

Without these conditions, ITC cannot be claimed.

Payment to Supplier Within 180 Days

If payment to the supplier is not made within 180 days from the invoice date:

• ITC claimed must be reversed along with interest.
• ITC can be reclaimed once payment is made.

Example

• Purchase Invoice: ₹1,00,000 + GST ₹18,000
• ITC claimed: ₹18,000
• Supplier not paid within 180 days

Result:

• ITC of ₹18,000 to be reversed.
• Reclaim allowed after payment.

ITC relating to an invoice or debit note can be claimed up to:

30th November of the following financial year or

Date of filing Annual Return

whichever is earlier.

Example

Invoice Date: 15 July 2025

FY: 2025-26
