Eligibility and Conditions for Taking ITC (Section 16 CGST)
Updated 4 October 2026 · Fact-checked
Section 16 of the CGST Act, 2017 lets a registered person take ITC on supplies used in business, but only if the main conditions are met: a valid tax invoice or other document, receipt of goods or services, tax actually paid to the government, and the return filed. Claim also must be within the Section 16(4) time limit.
Understand Eligibility and Conditions for Taking ITC (Section 16)
Input tax credit (ITC) is the GST you paid on purchases, which you set off against the GST you collect on sales. Without ITC, tax would pile up at every stage of the supply chain. Section 16 is the gate. It decides whether you can take the credit at all.
The first test is who and why. Only a registered person can claim, and only for goods or services used or intended to be used in the course or furtherance of business. Purchases for personal use do not qualify. A composition dealer under Section 10 cannot claim ITC. Credit that passes Section 16 can still be blocked by Section 17(5), so check that section separately.
The second test is the list of conditions in Section 16(2). Think of them as a chain: document (tax invoice, debit note or other prescribed document), supplier reporting (the supplier has furnished the invoice details in their outward supplies statement and they reach you through your auto-generated statement, with the credit not restricted), receipt (you have received the goods or services), tax paid (the tax charged has actually reached the government) and return (you have filed your return under Section 39). If any link breaks, the credit is not available for now.
The third test is time and payment to your supplier. Under Section 16(4) you cannot take credit after the 30th November following the end of the financial year to which the invoice or debit note pertains, or the date of filing the annual return, whichever is earlier. Separately, under the second proviso to Section 16(2), if you do not pay your supplier within 180 days of the invoice date, you must add back the credit with interest under Section 50 (interest at the Section 50(1) rate under Rule 37). Interest runs from the date you availed the credit until the date you reverse it. You can take the credit again once you pay.
Two more rules complete the picture. If you claim depreciation on the tax component of a capital asset, you cannot also claim ITC on that tax component (Section 16(3)). If goods come in lots, you take credit only when the last lot arrives.
Key rules to remember
- Basic eligibility (Section 16(1))
- Registered person + supply used or intended to be used in course or furtherance of business → ITC credited to electronic credit ledger
- Subject to the conditions of Section 16 and the blocks in Section 17(5).
- Conditions in Section 16(2)
- Valid document + supplier has reported the invoice and credit not restricted + goods/services received + tax paid to government + return under Section 39 filed
- All must be satisfied. Missing even one denies the credit until it is cured.
- Deemed receipt
- Goods delivered to a third person on your direction, or services provided to a third person on your direction = received by you
- Applies whether the third person acts as your agent or otherwise. Covers bill-to-ship-to cases.
- Goods received in lots
- Credit allowed on receipt of the last lot
- Applies when goods against one invoice come in lots or instalments.
- Tax paid to government (Section 16(2)(c))
- Tax charged on the supply must be paid by the supplier in cash or by using admissible ITC
- If the supplier has not paid, the condition is not met and credit can be denied.
- 180-day payment rule (second proviso to Section 16(2))
- If supplier not paid value + tax within 180 days from invoice date → add ITC to output tax liability, with interest under Section 50 (interest at the Section 50(1) rate under Rule 37) from the date of availing the credit to the date of reversal; re-avail after payment
- Applies to the amount not paid. The proviso does not apply to supplies on which tax is payable under reverse charge. It also has no work to do where no consideration is payable, because there is nothing to pay.
- Time limit (Section 16(4))
- Last date = earlier of (30 November following the end of the financial year of the invoice/debit note) and (date of furnishing the annual return)
- Example: invoice of FY 2025-26 → 30 November 2026 at the latest.
- Depreciation on tax component (Section 16(3))
- Depreciation claimed on tax part of capital goods → no ITC on that tax part
- Choose one: ITC or depreciation on the GST portion.
How to solve Eligibility and Conditions for Taking ITC (Section 16) questions
Use this checklist on any Section 16 question. Write each step as a short heading in your answer. It reads as a clear provision-facts-conclusion answer and earns step marks.
- 1Check the claimant: is the recipient a registered person, and not a composition dealer? Is the supply for business use? If not, ITC fails at Section 16(1).
- 2List the Section 16(2) conditions one by one: tax invoice or other document, supplier's reporting and no restriction, receipt of goods or services, tax paid to government, return filed.
- 3Test each condition against the facts. Watch for deemed receipt, lot-wise delivery and cases where the supplier has not paid tax.
- 4Check the 180-day rule: has the recipient paid the supplier within 180 days of the invoice date? If not, compute the ITC to be added back and mention interest under Section 50 (interest at the Section 50(1) rate under Rule 37), from the date of availing to the date of reversal.
- 5Check Section 16(4): find the financial year of the invoice, then the 30 November after it, and compare with the annual return date. Take the earlier date.
- 6Check Section 16(3) if capital goods and depreciation are mentioned, and glance at Section 17(5) for blocked items.
- 7Compute the ITC allowed (usually the tax amount only, not the value of goods) and state a clear conclusion.
Quickest way: Condition tick-list and date check
When to use it: Use for MCQs and for short written parts. Read the facts once and tick each condition. The first failed condition usually gives the answer.
- For MCQs, hunt for the one fact that breaks a condition: goods not received, tax not paid by supplier, return not filed, time limit crossed, or payment to supplier delayed beyond 180 days.
- If all conditions are met, ITC equals the GST shown on the invoice. Ignore the basic value in your answer.
- For the time limit, fix the invoice's financial year first. Then add 30 November of the next year. Check whether the annual return was filed earlier.
- For the 180-day rule, count 180 days from the invoice date, not from the date of receipt of goods.
- In written answers, use this layout: Provision (Section 16(2)(x)), Facts (one line), Conclusion (allowed, denied or reverse with interest). Add the figure at the end.
Common mistakes in Eligibility and Conditions for Taking ITC (Section 16)
Treating the time limit as 30 November of the same year in which the invoice is dated.
Students link the deadline to the invoice date instead of the financial year to which the invoice pertains.
Fix: Find the financial year first. The deadline is 30 November following the end of that year, or the annual return filing date if earlier.
Allowing credit on a lot-wise purchase as soon as the first lot arrives.
Students focus on the invoice and forget the proviso on lots or instalments.
Fix: Credit is available only on receipt of the last lot, so check the date of the last lot.
Saying ITC is permanently lost when the supplier has not paid tax.
Students mix up denial of credit with permanent denial.
Fix: The condition in Section 16(2)(c) is not met for now, so credit is denied. State that credit can be taken once the condition is satisfied, within the Section 16(4) limit.
Missing the 180-day payment rule or applying it from the date of receiving goods.
Students think the rule is about the supplier, but it is about the recipient's payment to the supplier.
Fix: Count 180 days from the invoice date. If unpaid, add back the ITC on the unpaid amount with interest under Section 50 (interest at the Section 50(1) rate under Rule 37), from the date of availing to the date of reversal. Re-avail on payment.
Forgetting that deemed receipt counts for goods sent to a third person.
Students read receipt as physical receipt at the recipient's own premises.
Fix: If goods are delivered to another person on the recipient's direction, the recipient is treated as having received them. The condition is met.
Claiming ITC and depreciation on the same tax component of a capital asset.
Students forget Section 16(3), as depreciation is an accounting or income-tax topic.
Fix: If depreciation is claimed on the tax part, ITC on that part is not allowed. Mention this whenever capital goods appear in a question.
Worked examples
Example 1
Alpha Traders, a registered regular taxpayer, received goods on 10 February 2026 against a tax invoice dated 5 February 2026. It has not yet claimed the ITC. The supplier has paid the tax and Alpha Traders files its returns regularly. It furnishes its annual return for FY 2025-26 on 20 October 2026. Up to which date can Alpha Traders take the ITC?
Show the solution
- Provision: Section 16(4) bars credit after the 30th November following the end of the financial year to which the invoice pertains, or the date of furnishing the annual return, whichever is earlier.
- Facts: the invoice is dated 5 February 2026, so it pertains to FY 2025-26, which ends on 31 March 2026.
- The 30th November following the end of the financial year is 30 November 2026.
- The annual return for FY 2025-26 is furnished on 20 October 2026.
- The earlier of 30 November 2026 and 20 October 2026 is 20 October 2026.
Answer: Alpha Traders can take the ITC only up to 20 October 2026, the earlier of the two dates. Assuming the other conditions of Section 16(2) are met, credit claimed after that date would be time-barred.
Example 2
Beta Ltd, a registered person, purchased raw materials for use in its factory on 1 January 2026. The tax invoice shows value ₹1,00,000 plus GST ₹18,000, total ₹1,18,000. Beta Ltd took ITC of ₹18,000 on 5 January 2026 and has paid nothing to the supplier. It has not yet furnished its annual return for FY 2025-26. All other conditions of Section 16 are met. What is the position if Beta Ltd has not paid by the end of the 180-day period, and what happens if it pays the full amount on 10 September 2026?
Show the solution
- Provision: under the second proviso to Section 16(2), if the recipient does not pay the supplier the value of supply with tax within 180 days from the date of issue of the invoice, the ITC availed must be added to the output tax liability with interest under Section 50 (interest at the Section 50(1) rate under Rule 37).
- Facts: the invoice is dated 1 January 2026. Counting 180 days from that date (2 January is day 1) gives 30 June 2026 as the last day: 30 days to 31 January, 58 to 28 February, 89 to 31 March, 119 to 30 April, 150 to 31 May and 180 to 30 June.
- Beta Ltd has paid nothing by 30 June 2026, so the payment condition is not met.
- Amount to be added to output tax liability: the ITC of ₹18,000 on the unpaid supply.
- Interest under Section 50 (interest at the Section 50(1) rate under Rule 37) runs on ₹18,000 from the date of availing the credit, 5 January 2026, until the date Beta Ltd reverses it. The question gives no reversal date, so the interest amount is not computed.
- On payment of the full ₹1,18,000 on 10 September 2026, Beta Ltd becomes entitled to avail the ₹18,000 again, provided it is within the Section 16(4) time limit.
- Section 16(4) check: the invoice dated 1 January 2026 pertains to FY 2025-26. The limit is the earlier of 30 November 2026 and the date of furnishing the annual return. The annual return has not yet been furnished, so the limit is 30 November 2026. 10 September 2026 is before that date, so the re-availing is within time.
Answer: Beta Ltd must add back ₹18,000 to its output tax liability, with interest under Section 50 (interest at the Section 50(1) rate under Rule 37) from 5 January 2026 (the date of availing) to the date of reversal, because it did not pay the supplier within 180 days (by 30 June 2026). It can re-avail the ₹18,000 after paying the supplier on 10 September 2026. This is within the Section 16(4) limit of 30 November 2026, as the annual return has not been furnished earlier.
Exam tips
- Write the section and clause with each point, for example Section 16(2)(c) for tax paid and 16(4) for time limit. Examiners reward this precision.
- In date questions, show the working: financial year, 30 November, annual return date, and then the earlier of the two. Marks go to the working even if you slip on the final date.
- For MCQs, spot the one broken condition. Common triggers are supplier non-payment, goods not received, lot-wise delivery, and returns not filed.
- Always take ITC as the GST amount only. Do not include the basic value of supply in your answer.
- Link to Section 17(5) in one line when the facts mention personal use, motor vehicles or similar items. Section 16 may be satisfied while the credit is still blocked.

Eligibility and Conditions for Taking ITC (Section 16): frequently asked questions
What are the conditions for availing ITC under Section 16 of the CGST Act?
The recipient must be registered and use the supply for business. Under Section 16(2), they need a valid tax invoice or other prescribed document, the supplier must have reported the invoice details and the credit must not be restricted, they must have received the goods or services, the tax must have been paid to the government, and they must have filed their return under Section 39. They must also meet the Section 16(4) time limit.
What is the time limit for claiming ITC under Section 16(4)?
ITC for an invoice or debit note cannot be taken after the 30th November following the end of the financial year to which it pertains, or the date of filing the annual return, whichever is earlier. For an invoice of FY 2025-26, the outer limit is 30 November 2026.
Can I claim ITC if my supplier has not paid the tax to the government?
Under Section 16(2)(c), credit is allowed only if the tax charged has actually been paid to the government. If the supplier has not paid, the condition is not met and the credit can be denied. You can claim it once the condition is satisfied, within the time limit.
What is the 180-day rule under Section 16?
Under the second proviso to Section 16(2), if you do not pay your supplier the value of the supply along with the tax within 180 days from the invoice date, you must add the ITC to your output tax liability. Interest is payable under Section 50 (interest at the Section 50(1) rate under Rule 37), from the date you availed the credit until the date you reverse it. When you pay the supplier later, you can take the credit again.
Can I claim ITC on goods received in instalments?
Yes, but only when the last lot is received. You cannot claim ITC for earlier lots against the same invoice before the last lot arrives.
