Eligibility and Conditions for Taking Input Tax Credit under GST

Updated 11 October 2026 · Fact-checked

Input tax credit (ITC) lets a registered person take credit of GST charged on supplies used in business. Under Section 16(2) CGST Act you need a tax invoice or debit note, receipt of goods or services, tax actually paid to the Government, and a filed return. Time limit and other conditions also apply.

Understand Eligibility and Conditions for Taking Input Tax Credit

GST is charged at every stage of supply. If a business paid tax on its purchases and then charged tax on its sales, it would pay tax on tax. Input tax credit removes this. The tax you paid on inputs is set off against the tax you collect on outputs.

Section 16(1) gives the basic right. Every registered person is entitled to take credit of input tax charged on supplies of goods or services or both to him, which are used or intended to be used in the course or furtherance of his business. The credit goes to his electronic credit ledger. This is subject to prescribed conditions and restrictions.

Section 16(2) then adds conditions. It opens with "notwithstanding anything contained in this section", so a registered person gets no credit unless every condition is met. The conditions are: possession of a tax invoice or debit note issued by a registered supplier (or other prescribed tax paying documents); the supplier has furnished the invoice details in the statement of outward supplies and they are communicated to you; you have received the goods or services; the credit shown to you under Section 38 has not been restricted; the tax has actually been paid to the Government; and you have filed your return under Section 39.

Section 41 deals with availment. A registered person may avail the credit of eligible input tax, as self-assessed, in his return, and it is credited to his electronic credit ledger. If the supplier has not paid the tax on those supplies, the credit availed must be reversed along with applicable interest. If the supplier later pays the tax, you may re-avail the reversed credit.

Think of it in two layers. Section 16 says whether you are eligible. Section 41 says how you take the credit and what happens if the supplier defaults. In answers, always say which layer you are discussing.

Key rules to remember

Basic entitlement: Registered person + supply used or intended to be used in course or furtherance of business = ITC entitlement (Section 16(1)); Subject to prescribed conditions and restrictions. Credit goes to the electronic credit ledger.
Conditions under Section 16(2): Invoice/debit note (a) + supplier's reporting and communication (aa) + receipt (b) + credit not restricted under Section 38 (ba) + tax paid to Government (c) + return filed (d); All must be met. Missing any one means no credit for that supply.
Receipt in lots: Credit allowed on receipt of the last lot or instalment; Applies where goods against one invoice come in lots or instalments.
180-day payment rule: Payment to supplier not made within 180 days from date of invoice = amount equal to ITC availed must be paid with interest under Section 50; Not applicable to supplies on which tax is payable on reverse charge. Credit can be availed again on payment to the supplier.
Depreciation bar: Depreciation claimed on tax component of capital goods under the Income-tax Act, 1961 = no ITC on that tax component (Section 16(3)); Read exactly as in the text: the Act refers to the Income-tax Act, 1961.
Time limit: No ITC after 30 November following the end of the financial year of the invoice or debit note, or filing of the annual return, whichever is earlier (Section 16(4)); Check the date of the invoice, not the date of receipt.
Section 41 reversal: Supplier has not paid tax = recipient reverses ITC with applicable interest; may re-avail when supplier pays; Reversal is in the manner prescribed.

How to solve Eligibility and Conditions for Taking Input Tax Credit questions

Use this order for any problem asking whether ITC can be claimed.

1Check that the recipient is a registered person and that the supply is used or intended to be used in the course or furtherance of business.
2Check whether the supply falls under any bar, such as depreciation claimed on the tax component of capital goods under Section 16(3), or a blocked credit.
3Test each Section 16(2) condition one by one: document, supplier reporting and communication, receipt, no restriction under Section 38, tax paid, return filed.
4Apply the special rules: goods received in lots, deemed receipt where goods or services go to a third party on your direction, and the 180-day payment rule.
5Check the time limit under Section 16(4) using the financial year of the invoice.
6Apply Section 41: credit is availed in the return as self-assessed, and must be reversed with interest if the supplier has not paid tax.
7State the conclusion clearly: eligible, partly eligible, or not eligible, with the reason and section.

Quickest way: Six-condition checklist

When to use it: Use it for short-answer or case questions where you must decide quickly whether credit is allowed.

Write the six conditions as letters: Invoice, Reported by supplier, Received, Not restricted, Paid to Government, Return filed.
Tick or cross each against the facts given.
Any cross means credit is denied for now.
Then scan for traps: lots, 180 days, depreciation, 30 November deadline.
Write the conclusion with Section 16(2) or the relevant sub-section.

Common mistakes in Eligibility and Conditions for Taking Input Tax Credit

Claiming credit when the invoice is held but goods are not yet received.
Students treat the invoice as enough.
Fix: Section 16(2)(b) needs receipt as well. Remember the deemed receipt rule when goods are delivered to another person on your direction.
Claiming credit on each lot separately when goods come in instalments against one invoice.
Students link credit to physical receipt of each lot.
Fix: Credit is allowed upon receipt of the last lot or instalment.
Ignoring the supplier's side of the conditions.
Students think only of their own invoice and return.
Fix: Check that the supplier has furnished the invoice details and that the tax has actually been paid to the Government.
Applying the 180-day rule to reverse charge purchases.
The rule is remembered without its exception.
Fix: The proviso excludes supplies on which tax is payable on reverse charge.
Thinking reversed credit is lost for ever.
Students stop at the reversal.
Fix: Under Section 41 and the 180-day proviso, credit can be re-availed when the supplier pays the tax, or when payment is made to the supplier.
Using the date of receipt or payment for the Section 16(4) time limit.
Students mix up dates.
Fix: Use the financial year to which the invoice or debit note pertains. The cut-off is 30 November following that year, or the annual return, whichever is earlier.

Worked examples

Example 1

Sharma Traders, a registered person in Jaipur, buys goods worth ₹2,00,000 plus GST of ₹36,000 from a registered supplier. It holds the tax invoice and files its return, but the supplier has not paid the tax to the Government. State whether Sharma Traders can retain the credit of ₹36,000.

Show the solution

Provision: Section 16(2)(c) requires that the tax charged on the supply has actually been paid to the Government, subject to Section 41.
Section 41(2): where the tax payable has not been paid by the supplier, the credit availed must be reversed along with applicable interest, in the prescribed manner.
Facts: invoice and return are in order, but the supplier has not paid the tax.
Analysis: one condition fails, so the credit cannot be retained.

Answer: Sharma Traders must reverse the credit of ₹36,000 with applicable interest. If the supplier later pays the tax, it may re-avail the reversed credit in the prescribed manner.

Example 2

Meera Enterprises receives goods under one invoice in three lots in January, February and March. It receives the last lot in March. The invoice, supplier reporting, tax payment and return are in order. From which point can it take credit?

Show the solution

Provision: the first proviso to Section 16(2) says that where goods against an invoice are received in lots or instalments, credit is taken upon receipt of the last lot or instalment.
Facts: the last lot arrives in March.
Analysis: receipt under Section 16(2)(b) is treated as complete only on the last lot, so no credit is available in January or February.
Other conditions are satisfied, so credit can be taken after the March receipt, within the time limit of Section 16(4).

Answer: Meera Enterprises can take the full credit on the invoice only upon receipt of the last lot in March, provided the Section 16(4) time limit is met.

Exam tips

Quote Section 16(2) with the clause letters (a), (aa), (b), (ba), (c), (d). It shows precision.
Always give the conclusion in one clear sentence after the analysis.
For case questions, hunt for the hidden defect: late return, unpaid supplier, undelivered goods, depreciation claim.
Keep Section 16 (eligibility) and Section 41 (availment and reversal) separate in your answer.
Learn the 180-day proviso with its reverse charge exception and re-availment rule.
