Input Tax Credit Eligibility Under GST
Not every business, and not every purchase, qualifies for Input Tax Credit. Eligibility is decided by a specific set of conditions laid down under Section 16 of the CGST Act, and missing even one of them is usually enough for the tax department to deny or reverse a claim.
This page focuses only on eligibility — who is allowed to claim ITC, what conditions have to be met before a claim is valid, and how these conditions play out in real scenarios. For the full concept of ITC, how it is calculated, and how it is claimed step by step, see the Input Tax Credit .
Who Can Claim Input Tax Credit?
ITC eligibility starts with one basic requirement: the person claiming it must be registered under GST. Beyond that, the credit must relate to goods or services used in the course or furtherance of business.
Persons Eligible to Claim ITC
-
Regular registered taxpayers — manufacturers, traders, wholesalers, and service providers registered under GST
-
Input Service Distributors (ISD) — entities that receive invoices for services on behalf of multiple branches and distribute the credit among them
-
Persons paying tax under reverse charge — eligible for ITC on the tax they themselves pay, subject to the usual conditions
-
Casual and non-resident taxable persons — eligible for ITC in limited circumstances tied to their registration period
Who Cannot Claim ITC
-
Unregistered persons and businesses below the GST registration threshold
-
Taxpayers registered under the composition scheme — since they pay tax at a fixed rate and cannot pass on or claim credit
-
Persons whose GST registration has been cancelled, for the period after cancellation
-
Anyone claiming credit on purchases used purely for personal consumption
Registration Requirement for Claiming ITC
GST registration is the starting gate for ITC. A business cannot claim credit on any purchase made before the effective date of its registration, except in one specific situation: a newly registered person can claim ITC on inputs held in stock, and inputs contained in semi-finished or finished goods held in stock, as on the day immediately preceding the date they become liable to registration — provided the claim is made within the prescribed time and the relevant invoices are less than a year old.
Once registered, the GSTIN quoted on every purchase invoice has to match the buyer's own registration exactly. An invoice raised against the wrong GSTIN, or against a branch that is not separately registered where required, can make that portion of ITC ineligible even if the underlying purchase is genuine.
Conditions for Claiming ITC (Section 16 of the CGST Act)
A registered person can claim ITC only when all of the following are satisfied together — not any one of them in isolation.
1. Possession of a Valid Tax Invoice or Debit Note
The buyer must hold a tax invoice, debit note, or other prescribed document (such as a bill of entry for imports, or an Input Service Distributor invoice) issued in line with GST invoicing rules. The document should carry the correct GSTIN, invoice number, taxable value, and tax amount. Minor clerical errors, such as a wrong HSN digit or an incomplete address, do not by themselves disqualify the credit as long as the core details — GSTIN, invoice number, and tax amount — are accurate and the transaction itself is genuine.
2. The Credit Must Appear in GSTR-2B
Since the supplier-reporting system was tightened, ITC can be claimed only to the extent it is reflected in the buyer's auto-drafted GSTR-2B statement for that period. If a supplier has not filed their outward supply return, or has filed it with errors, the corresponding credit will not show up, and the buyer cannot claim it until the mismatch is resolved.
3. Receipt of Goods or Services
Credit can be claimed only after the goods or services have actually been received — not merely ordered or invoiced. Two situations are treated as deemed receipt:
-
Bill-to-ship-to transactions, where goods are delivered to a third party on the buyer's instruction, are treated as received by the buyer on the date of delivery to that third party.
-
Goods received in lots or instalments are eligible for ITC only after the last instalment or lot is received, not proportionately as each part arrives.
4. Tax Actually Paid to the Government
The supplier must have actually deposited the tax charged on the invoice with the government, either in cash or by using their own eligible credit. This condition sits behind the GSTR-2B requirement above — it is the reason unpaid or defaulting suppliers create ITC risk for their buyers.
5. Return Filing by the Recipient
The buyer must have filed their own GST return (GSTR-3B) for the relevant period. ITC cannot be claimed through any document outside the return filing process.
6. Payment to the Supplier Within the Prescribed Time
Where the buyer has not paid the supplier — including the tax component — within 180 days of the invoice date, the credit already claimed has to be reversed, along with applicable interest. It can be reclaimed once the payment is actually made. This condition does not apply to supplies under reverse charge or certain deemed-supply situations.
7. Use in the Course or Furtherance of Business
The underlying goods or services must be used, or intended to be used, for business purposes. Purchases for personal use, even if billed to a registered GSTIN, do not qualify.
What Happens If Any Condition Is Not Met?
If even one of the conditions above fails, the ITC either cannot be claimed in the first place, or has to be reversed if it was already claimed. Common consequences include:
-
The credit does not appear in GSTR-2B, so it stays blocked until the supplier corrects their filing
-
Wrongly claimed ITC has to be reversed along with interest, typically at a higher rate than standard interest on delayed tax
-
Repeated or large-value mismatches can trigger scrutiny or a formal notice from the tax department
Practical Examples of ITC Eligibility
Example 1 — Invoice not reflected in GSTR-2B A trader receives goods worth ₹5,00,000 plus ₹90,000 GST in a given month and books the purchase. However, the supplier has not yet filed their outward supply return, so the credit does not appear in the trader's GSTR-2B. The trader cannot claim this ₹90,000 until the supplier files correctly and the credit reflects in a later period's GSTR-2B.
Example 2 — Goods received in instalments A manufacturer places an order for machinery parts delivered in three separate consignments over two months. Even though invoices are raised for each consignment, ITC on the entire purchase can be claimed only after the third and final consignment is received.
Example 3 — Payment delayed beyond 180 days A company claims ₹40,000 as ITC on a service invoice in April but does not pay the supplier until November — more than 180 days later. The company has to reverse the ₹40,000 ITC (with interest) in the return where the 180-day limit lapses, and can reclaim it only after actually paying the supplier.
Example 4 — Composition dealer A retailer registered under the composition scheme buys goods worth ₹2,00,000 plus GST from a regular dealer. Because composition taxpayers are not eligible to claim ITC at all, the GST paid on this purchase becomes a cost, not a credit.
Example 5 — New GST registration A business crosses the registration threshold and obtains GST registration on 1 June. It holds unsold stock purchased in April, with valid invoices less than a year old. It can claim ITC on the GST paid on that opening stock, subject to filing the required declaration within the prescribed time — but not on any stock purchased before registration was mandatory and already sold before the registration date.
Frequently Asked Questions
Who is eligible to claim Input Tax Credit under GST?
Any person registered under GST, including Input Service Distributors and persons paying tax under reverse charge, can claim ITC on business purchases, provided the conditions under Section 16 are met. Composition scheme taxpayers and unregistered persons are not eligible.
Can ITC be claimed without GST registration?
No. GST registration is a mandatory precondition for claiming ITC, except for the limited case of ITC on stock held immediately before a new registration takes effect.
Is a tax invoice mandatory to claim ITC?
Yes. ITC can be claimed only on the basis of a valid tax invoice, debit note, or other prescribed document such as a bill of entry or ISD invoice.
Does ITC eligibility depend on the supplier paying tax?
Yes. If the supplier has not actually deposited the tax with the government, and it does not reflect in the buyer's GSTR-2B, the buyer cannot claim that credit.
What happens if payment to the supplier is delayed beyond 180 days?
The ITC already claimed on that invoice has to be reversed along with interest. It can be reclaimed once the payment is actually made to the supplier.
