Input Tax Credit Under GST Explained

Credit is a reduction of your tax, not a discount from the vendor

When you buy a taxable supply for the business, the supplier’s GST can become your input tax credit if the law allows it. You then use that credit on the payment screen of the summary return, in the order that screen applies. The commercial effect is that tax is meant to stick to the value you add, not to stack on every purchase along the chain. The mechanism is described from the other direction in .

Credit you have not claimed does not sit in the cash ledger. It is only a figure in a working paper until GSTR-3B says you are taking it. That is why the treats the credit table as a decision, not as an import. Decide first. File second.

The conditions, in the order a reviewer asks them

A working claim can answer five questions. Do you hold the tax invoice or other permitted document? Have you received the goods or services? Is the tax charged on that document actually the supplier’s liability, and have they reported the supply? Have you filed the return in which the credit is claimed? Are the goods or services used in the course or furtherance of business, and not blocked? If any answer is no, the credit waits or dies.

A further condition requires you to pay the supplier within the period the law prescribes, failing which the credit is reversed and may be reclaimed when you pay. The number of days is in the provision in force. This article does not print it. Diary the unpaid invoices. A credit that depends on a payment you have not made is a reversal waiting for a month-end.

There is a last return in which a year’s credit can be claimed

The law sets an outer return period for claiming credit that belongs to a financial year. Missing that return usually means the credit is lost, even if the invoice is perfect. The identity of that return has been amended, so read the year’s instructions rather than a remembered month. When you defer a credit because it is not yet on GSTR-2B, write the outer period on the deferral note so it cannot expire in a drawer.

Blocked credit is a statutory no, with exceptions

Some inward supplies are blocked even though GST was charged and the supplier filed the invoice. The list lives in the statute and has exceptions, and both the list and the exceptions have been amended. Illustrations that have commonly been restricted include motor vehicles for passenger transport, food and catering, memberships of clubs, goods or services used for personal consumption, and works contracts that result in immovable property for your own use. Do not treat that sentence as the complete current list.

The safe habit is a column on the purchase register: eligible, blocked, or needs a look at the exception. A blocked credit is still a real cost. Book it in the expense or the asset. Do not “claim it and reverse it later” as a way of parking the question in the credit ledger. The shows how an empty ineligible column becomes an over-claim.

Common credit when you also make exempt supplies

Inputs used partly for taxable supplies and partly for exempt supplies are not fully creditable. The rules set a method to apportion them. Apply that method from the provision in force, and keep the working. A business that has started an exempt line and continues to claim every purchase credit is apportioning nothing. Exempt turnover in the outward statement and full credit in the summary return is a pair a reviewer will notice.

GSTR-2B is the list, not the entitlement

GSTR-2B is a statement the portal prepares for a tax period from invoices your suppliers have reported. It does not move after it is generated for that period, which is why people call it static. GSTR-2A is the related view that keeps changing as suppliers file and amend. Use 2B as the list you tick for the claim, and use 2A only as a clue when you are chasing a supplier who has not yet landed on 2B.

Whether you may legally claim a credit that is absent from 2B depends on the section and rule for that period. The rule has been tightened over time. Before you claim an off-statement invoice, read the current condition and write why you believe it is met. Before you ignore a 2B line, write why: wrong GSTIN, blocked, not your supply, or deferred. Silence is how the same line is claimed twice, once by accident and once on purpose.

A contractor with one exempt site

A contractor in Nagpur has a taxable works contract for a private factory and a separate exempt supply for a local body. Cement bought for the factory is a candidate for credit if the other conditions hold. Cement that cannot be traced to either site is common credit and has to be apportioned. The same supplier invoice covering both sites is not “half eligible” by guesswork. It is eligible only to the extent the working paper measures.

The contractor’s clerk also finds a dealer GSTIN on two invoices that Search Taxpayer shows as cancelled. Those lines are on an older 2B and absent from the latest one. Credit already claimed in a prior period is reviewed; credit not yet claimed is stopped. The is doing more work here than any rate lookup. Payment to the cement supplier is still inside the statutory window, so no reversal for non-payment is due this month. The diary says when that window closes.

A credit checklist for the period

Close credit in this order. 1. Download GSTR-2B for the period and freeze the purchase register. 2. Match supplier GSTIN, invoice number, and tax to the register, and search any GSTIN you do not already trust. 3. Mark each matched line eligible, blocked, common, or deferred, with a reason. 4. Apply the apportionment method to common credit and keep the sheet. 5. List invoices unpaid beyond the statutory period and reverse what the rule requires. 6. Claim the eligible net in GSTR-3B and nowhere else. 7. Note the outer return period for anything you deferred, so the year’s credit does not expire unseen.

Reverse-charge tax you paid in cash can itself be a credit when the inward supply is eligible. That claim is still a separate tick, not an automatic net-off against the liability. The keeps the liability and the credit in two columns so they are not collapsed.

Confirm the year’s credit rule before you rely on a habit

Blocked categories, the match to the inward statement, the payment window, and the last period for a year’s credit are all statutory and all have been amended. Read them on the GST portal return instructions and on CBIC GST for the period you are closing. A working paper that cites “the usual rule” without a date is not a working paper.

The makes you mark a sample 2B until the four outcomes — claim, defer, block, reverse — feel ordinary. That is the skill. The amounts are just the register you already have.
