Input Tax Credit (ITC)

GST paid on business purchases that can be claimed as credit against output GST liability

Definition

Input Tax Credit (ITC) is the GST that a business pays on its purchases (inputs) which can be claimed as a credit to reduce the GST liability on its sales (output). In simple terms, you only pay the difference between the GST you collected from customers and the GST you already paid to suppliers. ITC is the backbone of India's GST system, designed to eliminate the cascading effect of tax-on-tax that existed under the earlier VAT and excise regime. To claim ITC, you must hold a valid tax invoice, the goods or services must be used for business purposes, the supplier must have filed their return and paid the tax, and the purchase must reflect in your GSTR-2B. ITC cannot be claimed on certain items like personal-use goods, motor vehicles (with exceptions), food and beverages, and membership of clubs. Businesses must claim ITC within the due date of filing the return for September of the following financial year or the date of filing the annual return, whichever is earlier. Proper purchase record-keeping and invoice matching are essential to maximise your ITC claims.

How It Works

  1. 1When you purchase goods or services for your business, the GST charged by the supplier is recorded as Input Tax Credit in your electronic credit ledger on the GST portal.
  2. 2When you sell goods or services, the GST collected from your customers becomes your output tax liability.
  3. 3While filing GSTR-3B, you offset your output tax liability against the accumulated ITC — the difference is the net tax you actually pay to the government.
  4. 4ITC eligibility is verified through GSTR-2B, which auto-populates from your suppliers' GSTR-1 filings, ensuring that credit is only claimed on genuine, tax-paid purchases.

Example

You run a furniture shop in Jaipur. In March, you sell furniture worth Rs. 5,00,000 and collect 18% GST = Rs. 90,000 (output GST). During the same month, you purchased wood and materials worth Rs. 3,00,000 and paid 18% GST = Rs. 54,000 (input GST). Your net GST payable = Rs. 90,000 - Rs. 54,000 = Rs. 36,000. The Rs. 54,000 you paid on purchases is your Input Tax Credit, which saves you from paying the full Rs. 90,000 to the government.

How Stock Register Handles This

  • Automatically track GST paid on every purchase invoice to maintain an accurate running total of available Input Tax Credit
  • Match your ITC claims against GSTR-2B data to identify mismatches, missing invoices, or ineligible credits before filing returns
  • Generate ITC summary reports by month, supplier, or GST rate to plan tax payments and ensure you are claiming every eligible credit
  • Flag purchases where the supplier has not filed their return, so you can follow up and protect your ITC eligibility

Formula

Net GST Payable = Output GST (on sales) - Input Tax Credit (on purchases)

Frequently Asked Questions

What are the conditions for claiming Input Tax Credit?

To claim ITC, you must have a valid GST tax invoice, the goods or services must be received, the supplier must have filed their GSTR-1 and paid the tax (reflected in your GSTR-2B), and you must have filed your own GSTR-3B. Additionally, the purchase must be for business purposes and not fall under the blocked credit list.

What happens if my supplier does not file their GST return?

If your supplier has not filed their GSTR-1, the invoice will not appear in your GSTR-2B, and you cannot claim ITC on that purchase. You should follow up with the supplier to file their return. Under the current rules, ITC is provisionally available only if it appears in your GSTR-2B.

Can I claim ITC on all business purchases?

No, certain purchases are blocked from ITC under Section 17(5) of the CGST Act. These include motor vehicles (except for specific businesses), food and beverages, outdoor catering, beauty treatment, health services, club memberships, and goods or services used for personal consumption.
