Input Tax Credit — How ITC Works in GST

Input Tax Credit (ITC) prevents tax-on-tax cascading. Here is how to claim it, what conditions apply, and how GSTR-2B helps you claim the right amount.

Introduction

Before GST, a manufacturer paid excise duty on raw materials, then VAT on the finished product — and could not set off the excise paid on inputs against the VAT owed. The result was tax-on-tax: the same value was taxed multiple times as it moved through the supply chain.

ITC is the GST system's solution. Every registered business can subtract the GST paid on inputs from the GST collected on outputs. Done correctly, GST is paid only once — by the final consumer — while each business in the chain recovers what it paid.

Key concepts

What ITC means

Input Tax Credit lets a registered business deduct the GST it paid on purchases from the GST it owes on sales. Instead of paying the full GST to the government, you pay only the difference.

ITC conditions

You can claim ITC only when: you have a tax invoice, the goods or services were received, the supplier has filed their return, and the ITC is related to a business use.

ITC on inputs vs capital goods

ITC is available on inputs (raw materials, services used in production) and capital goods (plant and machinery). Capital goods ITC is also available, though depreciation and ITC cannot both be claimed on the same amount.

ITC on job work

A manufacturer can send inputs to a job worker and claim ITC, as long as the job worker returns the processed goods within the time limits prescribed under CGST Rules.

What ITC cannot be claimed on

Motor vehicles for personal use No (exceptions for motor cycles in certain cases)

Frequently asked questions

What is input tax credit?
Input Tax Credit (ITC) means a business can subtract the GST it paid on purchases from the GST it collected on sales. If you bought goods for ₹11,800 (including ₹1,800 CGST) and sold them for ₹23,600 (including ₹3,600 CGST), you owe only ₹1,800 to the government (₹3,600 minus ₹1,800 ITC). This prevents tax-on-tax cascading.

What documents do I need to claim ITC?
You need a valid tax invoice from your supplier (or a debit note), proof that the goods or services were received, and confirmation that your supplier has filed their GSTR-1 (so the ITC can be matched in GSTR-2B). Without a valid tax invoice, ITC cannot be claimed.

Can I claim ITC on personal purchases?
No. ITC can only be claimed on purchases used for business purposes. If you buy a car for personal use, the GST on that purchase cannot be claimed as ITC. If the car is used partly for business, you can claim a proportionate ITC.

What is GSTR-2B?
GSTR-2B is an auto-drafted statement that GST portals generate from your suppliers' filed returns. It shows the ITC you are eligible to claim for a given tax period. You should use GSTR-2B as the basis for your ITC claims — not your own records of what you purchased.

Where can I read the CGST Rules on ITC?
Chapter X of the CGST Rules 2017 (rules 36–45) covers ITC eligibility, the GSTR-2B statement, and the time limits for claiming ITC. The rules are available on cbic.gov.in.
