Input Tax Credit (ITC)

Input Tax Credit (ITC): Input Tax Credit (ITC) is the GST a registered business pays on its purchases, which it can set off against the GST due on its sales. Section 16 of the CGST Act allows it only against a valid invoice, actual receipt, tax paid by the supplier and the invoice reflected in GSTR-2B. Lenders read ITC to verify purchases and detect fake-invoice risk.

Why Input Tax Credit (ITC) matters in credit and collections

• Section 16 conditions include possession of a tax invoice, receipt of goods or services, payment of tax by the supplier, filing of the recipient's return and the invoice being communicated to the recipient through GSTR-2B.
• Section 17(5) blocks credit on specified items, and ITC must be reversed if the supplier is not paid within 180 days of the invoice date.
• Underwriters compare ITC claimed in GSTR-3B with ITC available in GSTR-2B; persistent excess claims indicate compliance risk and possible fake invoices.
• The split of tax paid through credit versus cash indicates value addition; a business with large sales that pays almost no tax in cash merits a closer look.

How ITC works and what it reveals to a lender

GST is levied at each stage of supply, and ITC is what prevents tax from cascading. A trader that pays tax on purchases and charges tax on sales remits only the difference: output tax less eligible ITC, with any balance paid in cash from the electronic cash ledger. Credit sits in the electronic credit ledger and is set off against integrated, central and state tax liabilities in the order the law prescribes.

Eligibility is conditional. Under Section 16 the recipient must hold a tax invoice or debit note, have received the goods or services, and see the supplier's invoice communicated in its GSTR-2B; the supplier must actually have paid the tax, and the recipient must have filed its return. Credit must be claimed within the time limit in Section 16(4) and is reversed if the supplier is not paid within 180 days. Section 17(5) blocks credit on items such as certain motor vehicles, food and beverages and works contracts for immovable property, and Rule 88D requires taxpayers to explain ITC claimed in GSTR-3B in excess of GSTR-2B beyond a prescribed threshold.

For underwriting, ITC tells three stories. Purchases: ITC available in GSTR-2B shows whom the borrower buys from and how much, which tests whether declared sales are plausible. Compliance: ITC claimed in GSTR-3B that persistently exceeds GSTR-2B suggests reliance on invoices suppliers never reported, a recognised pattern in fake-invoice networks and a source of future tax demands. Margin: the share of output tax paid in cash rather than through credit indicates value addition; a business with large turnover that pays almost no cash tax may be a pass-through or circular-trading entity.

How lenders use ITC in MSME underwriting

• Reconcile ITC claimed in GSTR-3B with ITC available in GSTR-2B month by month, and ask about persistent gaps.
• Compare purchases implied by ITC with sales in GSTR-1 for a margin plausible for the trade.
• Look at the cash-versus-credit split of tax paid; near-zero cash payment on high turnover deserves scrutiny.
• Check the GST status and filing history of the largest suppliers; cancelled or non-filing suppliers put the borrower's credit at risk.
• Watch for ITC reversals and demand notices, which are cash-flow events that can hit repayment capacity.
