A Ring Road embroidery unit bought a new machine in March 2026 for ₹24 lakh plus 18% GST — ₹4.32 lakh of input tax credit sitting on one invoice. The supplier filed late, the invoice never showed in the owner's GSTR-2B that month, and nobody looked at it again. In the first week of December 2026 that ₹4.32 lakh will quietly stop being a credit and become a cost. This is the Section 16(4) cut-off, and it arrives every year on the same date.

What Section 16(4) actually says

Section 16(4) of the CGST Act, 2017 — in plain terms, you cannot take input tax credit on an invoice or debit note after 30 November following the end of the financial year to which that invoice pertains, or after you furnish the annual return for that year, whichever comes first. Example: a fabric invoice dated 18 August 2025 belongs to FY 2025-26, so its credit must be claimed by 30 November 2026. The same rule makes 30 November 2027 the wall for April 2026 purchases.

Two things in that sentence surprise people. First, the test is the date of the invoice, not the date you received the goods or paid the bill. Second, the second limb — the annual return — can pull the deadline earlier than 30 November. Hold that thought; it comes back below.

Claimed means claimed in a filed GSTR-3B

Seeing an invoice in your books or in GSTR-2B is not "taking" the credit. Credit is taken when you include it in Table 4 of a GSTR-3B that you have filed. Example: a Surat trader who tallies the invoice in October but files the GSTR-3B on 25 November has claimed it in time — but the same trader who plans to "clean it up in the November return" has not, because that return is due on 20 December.

That is why the working deadline is not "30 November" but "the last GSTR-3B I can file on or before 30 November". For a monthly filer that is the October 2026 return, due 20 November. For a business on the QRMP scheme, there is no monthly return in October or November, and the next quarterly return (October to December) falls due in January 2027 — so the July to September quarterly GSTR-3B, due around 22 to 24 October, is effectively the last window. That one catches people.

Why the invoice may not be in your GSTR-2B

Under Section 16(2)(aa), credit is available only if the invoice appears in your GSTR-2B — which means your supplier must have filed GSTR-1 (or IFF) reporting it. Example: your yarn supplier in Pandesara files GSTR-1 for March 2026 only in July 2026. That invoice shows up in the July GSTR-2B, not the March one — and it is still inside the FY 2025-26 window, because the cut-off runs from the invoice date. But a supplier who never reports it at all leaves you with a bill you paid in full and credit you cannot take.

The deadline is yours, but the data that unlocks it sits with your suppliers.

Since October 2024 the portal also shows these invoices on the Invoice Management System, where doing nothing is treated as acceptance. Check IMS before the 14 November GSTR-2B is generated, so that nothing you want to claim is rejected or left pending by habit.

The trap inside the second limb: GSTR-9

Because the section says "whichever is earlier", filing the annual return for FY 2025-26 closes the window for that year on the day you file it. Example: a Surat trader whose turnover is above ₹2 crore files GSTR-9 on 10 November because the accountant is free that week. A credit of ₹90,000 he spots on 20 November can no longer be claimed for FY 2025-26 — the 30 November date did not matter; his own filing date did.

The practical rule is simple: do not file GSTR-9 until the October 2026 GSTR-3B has been filed and every eligible credit is in. GSTR-9 is due on 31 December 2026, so there is no benefit in rushing it ahead of the cut-off. (Businesses under ₹2 crore of turnover can skip GSTR-9 for the year, in which case 30 November applies as it stands.)

Other things that ride on the same date

• Credit notes and debit notes. Under Section 34(2), a supplier's credit note that reduces their tax liability must also be reported by 30 November following the year-end, or the date of the annual return, whichever is earlier. If you expect a discount or sales return credit note for FY 2025-26, get it issued and reported in time.
• The 180-day payment rule. Under the second proviso to Section 16(2) and Rule 37, if you have not paid a supplier within 180 days of the invoice date, the credit must be reversed with interest, and may be taken again once you pay. A March 2026 invoice crosses 180 days in September 2026 — worth checking alongside the reconciliation.
• Earlier years. Sections 16(5) and 16(6), inserted by the Finance (No. 2) Act 2024, gave retrospective relief for older years, and Circular 237/31/2024-GST explains the procedure. They do not extend the FY 2025-26 date.

A four-step check for the next three weeks

• This week: download the GSTR-2B for every month of FY 2025-26 and match it with your purchase register by invoice number and value; list what is missing.
• By 20 October: send the missing-invoice list to each supplier and ask when they will report it. QRMP filers should file the July to September GSTR-3B with everything that is already available.
• By 14 November: check the October GSTR-2B for the invoices you chased and clear IMS actions.
• By 20 November: file the October GSTR-3B including the credit, and only then file GSTR-9.
