Input Tax Credit (ITC) is a core concept under the Goods and Services Tax (GST) in India that lets businesses offset the GST they’ve paid on purchases (inputs) against the GST they owe on their sales (output tax). This mechanism eliminates the cascading effect of tax‑on‑tax, lowers overall tax costs and improves cash flow for GST‑registered businesses. When conditions are met, ITC reduces the net GST payable, as credit accumulated for tax paid on inputs can be utilised in set order against output tax liabilities.

What Is Input Tax Credit (ITC)

Input Tax Credit (ITC) is the credit of GST that a registered person can claim on the tax paid for inward supplies of goods or services used in the course or furtherance of business. The credit is then used to reduce the tax payable on outward supplies, making the GST regime cost‑efficient and transparent. If a manufacturer pays GST on raw materials and later collects GST on finished goods, they can subtract the GST already paid (ITC) from the GST collected before remitting the balance to the government.

Who Is Eligible to Claim ITC

To claim ITC under the GST law, the claimant must meet key eligibility criteria:

You must be a registered person under GST (regular taxpayer).
The goods or services must be received and used or intended to be used in the course or furtherance of business.
A valid tax invoice or debit note must be available as proof of the inward supply.
The supplier must have paid the GST to the government and filed returns so that the credit is reflected in your records (e.g., GSTR‑2B).

If these conditions are satisfied, the ITC becomes available for utilisation in your electronic credit ledger.

Key Conditions to Claim ITC

Section 16 of the CGST Act outlines conditions that must be fulfilled before taking ITC:

1. Valid Invoices / Documents

You must possess tax invoices, debit notes or prescribed documents issued by a GST‑registered supplier showing GST charged on the purchase.

2. Receipt of Goods or Services

ITC can be claimed only after you have received the goods or services. If goods arrive in installments, ITC is claimed after the final lot is received.

3. Tax Paid to Government by Supplier

The supplier’s GST must be paid to the government and reflected in returns before you can claim ITC. This ensures that credit is claimed on tax actually remitted.

4. Return Filing Compliance

You must have filed necessary GST returns (like GSTR‑3B) for the tax period in which ITC is claimed. ITC claims must also align with your GSTR‑2B auto‑drafted statement.

5. Business Purpose Only

ITC is available only if the goods or services are used for business purposes, not for personal use. Exempt supplies or non‑business usage block credit.

6. Time Limit to Claim ITC

You must claim ITC on or before the earlier of:

The due date for filing the annual return for the relevant financial year, or
The due date of filing the return for September following that year.

What Can Be Claimed as Input Tax Credit

Eligible ITC typically includes:

GST paid on raw materials and inputs used in production.
GST paid on input services like logistics, rent, utilities used in business.
GST paid on capital goods (machinery, equipment) used in business, subject to conditions.

Credits cannot be claimed for personal use items, exempt supplies, and blocked credits under Section 17(5) of the CGST Act unless used for taxable purposes.

Benefits of Claiming ITC

ITC provides several advantages:

Reduces GST liability: The tax already paid on inputs lowers the amount payable on output supplies.
Improves cash flow: Businesses do not pay tax on taxes already borne earlier in the supply chain.
Avoids cascading tax: Ensures that tax is charged only on value addition, not on previous tax elements.

Common Scenarios Affecting ITC

If invoices are not received or matched in returns, ITC cannot be claimed.
If inputs are used partly for exempt supplies, ITC must be apportioned proportionately.
Failure to pay suppliers within 180 days may require ITC reversal with interest.

Conclusion

Input Tax Credit (ITC) is a fundamental feature of the GST regime in India that allows GST‑registered businesses to claim credit for tax paid on inward supplies and set it off against tax payable on outward supplies. To benefit from ITC, taxpayers must meet eligibility criteria, including valid documentation, receipt of goods and services, supplier compliance, and timely return filing and ensure the supplies are used in the course or furtherance of business. Following these rules helps reduce tax liability, improve cash flow and avoid double taxation.
