When can a business take input tax credit?
Section 16(4) of the Central Goods and Services Tax Act, 2017 sets the ordinary deadline for taking input tax credit (ITC) on an invoice or debit note. Sections 16(5) and 16(6) address specified historical claims and qualifying cases where a cancellation of registration was revoked. They override the time restriction to the extent stated. They do not remove other eligibility conditions, such as those in Sections 16(2) and 17, or cure deficiencies unrelated to timing.
How the deadline changed
- Original rule: The earlier of the due date for the Section 39 return for September after the end of the relevant financial year (FY), and the date the relevant annual return was actually furnished. Check period-specific extensions and provisos: for example, the original FY 2017–18 proviso allowed certain credits through the March 2019 return due date, subject to supplier reporting conditions.
- Finance Act, 2022: Section 100 replaced the September return due date with 30 November after the relevant FY. The amendment commenced on 1 October 2022 under Notification 18/2022–Central Tax. It therefore governed the FY 2021–22 cut-off as well as later years. Actual filing of the relevant annual return, if earlier, still cuts off the claim.
- Finance (No. 2) Act, 2024: Section 118 inserted Sections 16(5) and 16(6) with deemed effect from 1 July 2017. The changes are limited exceptions, and they operate independently.
Constitutional challenges and the statutory response
Taxpayers argued that accrued ITC deserved constitutional protection, that the overriding language in Section 16(2) displaced the time limit, and that early implementation problems made timely compliance difficult. In Gobinda Construction and connected petitions, the Patna High Court upheld the validity of the time restriction and treated eligibility and timing as distinct conditions. The judgment describes the position in those petitions; it does not displace the subsequently enacted relief. A portal difficulty or a constitutional argument is not by itself a general extension of the deadline.
The two exceptions
Section 16(5): For an invoice or debit note relating to FY 2017–18, 2018–19, 2019–20 or 2020–21, the credit can be taken in a Section 39 return filed on or before 30 November 2021. Verify the actual filing date and that the return included the claim. The amendment does not reopen a return today or validate the credit on other grounds.
Section 16(6): The cancellation must have been revoked under Section 30 or pursuant to an appellate authority, tribunal or court order. On the date of the cancellation order, Section 16(4) must not already have barred the particular invoice or debit note. Credit can then be taken in a Section 39 return under the ordinary deadline in Section 16(4), or in the return or returns for the period from the effective date of cancellation until the revocation order if filed within 30 days of that order, whichever route permits the later claim. The cancellation order date, its effective date and the revocation order date serve different purposes. Section 16(6) has no independent 30 November 2021 deadline.
Financial year at a glance
| Financial year | Applicable provision | Filing cut-off |
|---|---|---|

Notices, appeals and refunds
Under CBIC Circular 237/31/2024-GST, the officer should take the retrospective amendments into account during an investigation or adjudication. If an appeal is pending, raise the applicable amendment before the appellate authority. If an appeal against a cancellation order is pending, the circular also explains how the revocation outcome can affect ITC. If an eligible demand order under Section 73, 74, 107 or 108 was not appealed, Notification 22/2024–Central Tax established a special electronic rectification route, with a six-month application window from its issue on 8 October 2024. Treat that window as historical; check the order, any timely filing and remedies still open in the case. Relief concerns the affected ITC issue and does not extinguish unrelated parts of a demand. Do not withdraw a pending appeal simply because the law changed.
Section 150 of the Finance (No. 2) Act, 2024 bars refund of tax paid or ITC reversed where the payment or reversal would not have been necessary had Section 118 been in force at all material times. Identify what each amount represents. CBIC’s 25 October 2024 corrigendum expressly distinguishes statutory appeal pre-deposits under Sections 107(6) and 112(8) when the appeal is decided in the taxpayer’s favour.
Seven worked illustrations
1. Capital goods credit and a pending notice
Precision Forgings claims ₹65 lakh of FY 2018–19 capital goods ITC in its October 2021 GSTR-3B, filed on 18 November 2021. A 2023 Section 73 notice disputes timing and states ₹48 lakh in interest, making the stated demand ₹113 lakh (₹1.13 crore). The return was filed 12 days before 30 November 2021. If all other ITC conditions hold and timing is the sole issue, present the return and claim trail so the officer can drop that ground and its consequential interest. The ₹48 lakh is an assumed notice figure, not a verified interest calculation; determining any actual liability requires the applicable law, utilisation and payment dates and the credit ledger.
2. Revocation and a later eligible return
In the historical illustration, TechSolutions has ₹28 lakh of FY 2019–20 ITC and takes it in back returns filed on 20 September 2021, after revocation in August. Those returns were before 30 November 2021, so Section 16(5) can address timing. The month of revocation alone cannot establish the 30-day condition in Section 16(6).
For a distinct Section 16(6) example, assume a cancellation order dated and effective 1 June 2022, an otherwise eligible April 2022 invoice, a revocation order on 1 February 2024 and the applicable return for the cancellation period filed on 20 February 2024. The invoice was not time barred at cancellation. The ordinary deadline was 30 November 2023 assuming no earlier annual return; the cancellation-period return was filed 19 days after revocation, within the special 30-day window. This illustrates the later route under Section 16(6).
3. Payment under protest
Apex Logistics paid ₹18 lakh of disputed FY 2017–18 tax and ₹8 lakh described as interest through DRC-03, totalling ₹26 lakh. If the tax would not have been payable had Section 118 applied, Section 150 bars its refund on that basis. The words “under protest” do not automatically change the character of the payment. Identify the separate interest component and assess its legal treatment and available remedies on the records; the example does not assume a refund or a court outcome.
4. A debit note issued in a different financial year
The original invoice has a taxable value of ₹10 lakh and is dated January 2021. A genuine debit note for an additional taxable value of ₹2 lakh is dated 15 November 2022. At an assumed 18% GST rate the additional GST is ₹36,000. For the debit note the relevant year is FY 2022–23, so the ordinary cut-off is 30 November 2023 or earlier annual filing. A claim in a timely November 2022 GSTR-3B meets the time test; eligibility still depends on the other conditions.
5. Invoices found after the ordinary deadline
A manufacturer finds three FY 2023–24 capital equipment invoices in December 2024 with ₹12 lakh of omitted credit. The ordinary deadline was no later than 30 November 2024; Section 16(5) does not apply. Unless a separate exception applies, the amount is time barred even if the portal accepts an entry. Review the accounting treatment for any irrecoverable amount under the applicable standards and facts, including capitalisation or correction as appropriate.
6. Appeal pre-deposit on a timing demand
A March 2024 Section 73 order, summarised in DRC-07, confirms ₹38 lakh in disputed FY 2019–20 tax. Assume a timely appeal under Section 107 and no admitted amount: a 10% pre-deposit is ₹3.80 lakh. If the authority finds the return met Section 16(5) and decides the appeal in the taxpayer’s favour, the corrigendum confirms that Section 150 does not bar refund of that statutory pre-deposit. Obtain the order and follow the applicable refund process.
7. Financial statement disclosures
Modern Industrial discloses a ₹1.45 crore contingent liability for litigation. It should reassess the exposure at the reporting date, separating the timing issue from any surviving grounds and considering relevant legal advice. Under Ind AS 37, a contingent liability is generally disclosed unless the possibility of an outflow is remote. A disclosure is not a recognised provision and has no reversal journal entry; if a provision was separately recognised, assess it under the provision rules. The change does not guarantee a particular audit opinion.
Checklist for finance teams
- Record the financial year and document date for each disputed invoice or debit note, and match it to the actual Section 39 return and filing acknowledgement.
- Check annual return filing and the applicable cutoff, and review eligibility independently of timing.
- If relying on revocation, preserve the cancellation and revocation orders and the acknowledgements for each back return.
- Map the dispute stage, record tax, interest and pre-deposit separately, and submit the evidence through the applicable process.
- Reconcile purchase records with GSTR-2B where applicable before the earlier cutoff, and retain the return and ledger trail. Software can flag exceptions; staff must resolve and document them.
Frequently asked questions
1. What is the normal deadline?
30 November after the relevant FY, or the date the relevant annual return is furnished, if earlier. Plan around the filing date of the return that actually takes the credit.
2. Does Section 16(5) cover all years?
No. It covers the four FYs from 2017–18 through 2020–21 and requires an actual Section 39 filing taking the credit no later than 30 November 2021.
3. Can I recover tax paid or credit reversed before the amendment?
Section 150 bars recovery of the tax or credit it describes. An appeal pre-deposit in a successful appeal is treated separately under CBIC’s corrigendum.
4. Is a debit note tied to the original invoice year?
Under the amendment effective 1 January 2021, the date of issuance of the debit note determines its year for Section 16(4). CBIC explains the treatment of credit taken before and after the change in Circular 160/16/2021-GST.
5. What should I submit in a pending FY 2018–19 notice?
Give the officer the invoices or debit notes, the return acknowledgement and the ledger trail demonstrating that the credit was taken in a return filed by 30 November 2021. Ask the officer to give effect to Section 16(5) for the eligible timing issue; address other grounds separately.
6. What controls help prevent missed credits?
Reconcile regularly, assign owners to unmatched items and set alerts ahead of the statutory and annual return dates. Track exceptions through filing and preserve the supporting records.
