The ITC Time Limit: Section 16(4) and 30 November

ITC Time Limit explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.

Credit that is not taken in time is not deferred. It is lost.

Section 16(4) sets the deadline, and it is drafted as the earlier of two dates — which means filing the annual return early shortens your window.

A registered person shall not be entitled to take credit in respect of any invoice or debit note after the thirtieth day of November following the end of the financial year to which such invoice or debit note pertains, or furnishing of the relevant annual return, whichever is earlier. The deadline was moved from "the return for September" to 30 November by the Finance Act, 2022 with effect from 01.10.2022. The reference to "invoice relating to such debit note" was omitted by the Finance Act, 2020, so a debit note now stands on its own financial year.

The two dates

30 November following the end of the financial year. For FY 2025-26, that is 30 November 2026.

The date of furnishing the annual return for that year. The due date for GSTR-9 is 31 December, but a taxpayer who files on, say, 15 October 2026 has shortened their own deadline to 15 October.

The sub-section says "whichever is earlier". Filing the annual return early is a real and irreversible cost if credit is still to be identified.

What "pertains to" means

The limit attaches to the financial year to which the invoice or debit note pertains — not to when it was received, entered in the books, or paid.

An invoice dated 28 March 2026 pertains to FY 2025-26, even if it reached the recipient in June 2026. The deadline is 30 November 2026.

This is why late-arriving March invoices are a recurring loss. A supplier who bills in March and posts the invoice in July has consumed four months of the recipient's eight-month window without either party noticing.

Debit notes stand alone

Before the Finance Act, 2020, s.16(4) referred to "the invoice or invoice relating to such debit note". On that wording, a debit note's credit expired with the original invoice's financial year — so a debit note issued in 2026 for a 2023 supply carried no claimable credit at all.

The words "invoice relating to" were omitted with effect from 01.01.2021. The sub-section now reads "such invoice or debit note".

Consequence: a debit note issued in FY 2026-27 carries credit claimable up to 30 November 2027, regardless of when the underlying supply was made. That is what makes long-dated price escalations workable. Price escalation and debit notes →

What is outside section 16(4)

Re-availment under Rule 37(4). Credit reversed for non-payment within 180 days and re-availed on payment is expressly excluded from the s.16(4) limit. The 180-day rule →

Re-availment under Rule 37A. Credit reversed because the supplier did not file GSTR-3B, and re-availed once they do.

Sections 16(5) and 16(6). The retrospective relief for FY 2017-18 to 2020-21 and for revoked cancellations, both notwithstanding s.16(4). Sections 16(5) and 16(6) →

Reverse charge credit. Credit of tax paid under RCM is available in the period in which the tax is paid. Since the recipient issues its own self-invoice, the "invoice" for s.16(4) purposes is that self-invoice, whose financial year is the year of issue.

ITC-01 credit on registration. Section 18(1) has its own timeline — a declaration in FORM GST ITC-01 within thirty days of becoming eligible, and Rule 40(1)(b) limits it to invoices not older than one year from the date of the relevant event.

What happens when the deadline passes

The credit is extinguished. There is no application, no condonation, no discretionary extension.

Practical consequences:

• the tax paid to the supplier becomes a cost;
• if the credit was taken and utilised, a demand under s.73 or s.74A follows, with interest under s.50(3) and possible penalty;
• GSTR-9 Table 8C and Table 13 are where the mismatch surfaces — credit of the year availed in the next year up to the specified period;
• GSTR-9 Table 8E and 8F capture credit available but not availed, and available but ineligible.

Practical controls

• Run a purchase-register to GSTR-2B reconciliation monthly, not annually. Credit identified in November for a March invoice is credit found late.
• Chase missing supplier invoices before September, not after.
• Do not file GSTR-9 early unless the credit position is closed.
• Diarise 30 November as a hard internal cut-off, with a review two months before.
• Segregate debit notes in the reconciliation — they have their own financial year.
• Track reversals and re-availments separately, since the re-availments are outside the limit and should not be swept up in the same control.

Key takeaways

• Deadline: 30 November following the financial year, or the annual return date, whichever is earlier.
• It attaches to the year the invoice or debit note pertains to, not when it was received.
• A debit note stands on its own financial year since the Finance Act, 2020 amendment.
• Re-availment under Rules 37 and 37A is outside s.16(4).
• Sections 16(5) and 16(6) override it for specified years and for revoked cancellations.
• Filing GSTR-9 early shortens the window.
