GST ITC Deadline 30 November 2026: FY 2025-26 Reconciliation Checklist Under Section 16(4)

The GST ITC deadline of 30 November 2026 is the last date by which input tax credit on FY 2025-26 invoices and debit notes can be claimed under section 16(4) of the CGST Act — or the date you file the FY 2025-26 annual return (GSTR-9), if that comes first. Miss it and the credit is time-barred permanently, however genuine the purchase.

For finance heads and CA firms, the real risk is not the date itself. It is the gap between what sits in the purchase register and what can still be legally claimed in a return filed before the cut-off. This guide explains what the deadline covers, which return actually carries the claim, how GSTR-2B and IMS fit in, and a document-level checklist to close FY 2025-26 cleanly.

What section 16(4) actually says

Section 16(4) bars a registered person from taking ITC on an invoice or debit note after 30 November following the end of the financial year to which the invoice or debit note pertains, or after furnishing the relevant annual return, whichever is earlier.

Three points are worth stating plainly:

• It is a cut-off on entitlement, not an extension. It does not extend any return due date, and it does not make a credit available that fails any other test.
• "Taking" credit means claiming it in GSTR-3B. Recording an invoice in your books, or seeing it in GSTR-2B, is not a claim. The claim happens only when it is reported in a GSTR-3B furnished on or before the cut-off.
• Debit notes follow the year of the debit note, not the year of the original invoice. A debit note dated April 2026 against a FY 2025-26 invoice belongs to FY 2026-27.

Every other condition still applies alongside the time limit: a valid tax invoice or debit note (section 16(2)(a)), the supplier having reported it in GSTR-1/IFF so it appears in your GSTR-2B (section 16(2)(aa)), receipt of goods or services (section 16(2)(b)), tax actually paid to the government by the supplier (section 16(2)(c)), and your own return filing (section 16(2)(d)). Blocked credits under section 17(5) remain blocked regardless of date.

Which return carries the FY 2025-26 claim?

This is where most teams lose credit. The deadline is 30 November, but the return you file must exist and be filed by then.

Monthly GSTR-3B filers

The October 2026 GSTR-3B is effectively the last chance. If it is filed late — say on 2 December — any FY 2025-26 credit reported in it is outside section 16(4), even though the return itself is "October".

QRMP (quarterly) filers

For quarterly filers the practical deadline is therefore the July–September 2026 return due in late October 2026, not 30 November. It is due on 22 October 2026 for taxpayers whose principal place of business is in Maharashtra, Gujarat, Madhya Pradesh, Chhattisgarh, Karnataka, Goa, Kerala, Tamil Nadu, Telangana, Andhra Pradesh, Puducherry, Andaman and Nicobar Islands or Lakshadweep, and on 24 October 2026 for all other states and union territories. No extension has been notified for this quarter.

The annual return trap

The cut-off is the earlier of 30 November and the date of filing GSTR-9. The FY 2025-26 GSTR-9 is due on 31 December 2026, and the forms were enabled on the portal in October 2026. A business that files GSTR-9 early — say on 15 November — closes its own ITC window that day. Finish all ITC claims in GSTR-3B first, then file the annual return.

Under Notification No. 15/2025-Central Tax (17 September 2025), taxpayers with aggregate turnover up to ₹2 crore are exempt from filing GSTR-9 from FY 2024-25 onwards, so for them the 30 November date is the only cut-off. GSTR-9C (self-certified reconciliation statement) is required where aggregate turnover exceeds ₹5 crore.

GSTR-2B, IMS and supplier corrections

GSTR-2B is evidence, not permission

GSTR-2B is the static statement that shows what your suppliers reported. Section 16(2)(aa) makes its presence a condition, but its presence alone is not entitlement. GSTR-2B can show:

• invoices for goods not yet received;
• blocked items such as motor vehicles, food and beverages or works contract for immovable property;
• invoices already claimed in an earlier period;
• invoices with errors that the supplier later amends.

Each needs its own decision.

Supplier uploads and the October GSTR-2B

October 2026 GSTR-2B is generated on 14 November 2026 and picks up supplier documents filed up to the GSTR-1/IFF due date for that period (11 November for monthly GSTR-1, 13 November for IFF). Anything a supplier files after its due date appears in the GSTR-2B of the period in which it is actually filed — here, November's GSTR-2B, which arrives in mid-December, after the cut-off. The same applies to corrections through GSTR-1A: they reflect in the recipient's GSTR-2B for the next tax period. Supplier follow-up must therefore finish in the first ten days of November, not the last week.

Invoice Management System (IMS)

IMS lets the recipient accept, reject or keep pending each supplier document before GSTR-2B is generated. Things to remember for the deadline:

• Accepted and no-action (deemed accepted) records flow into GSTR-2B. Deemed acceptance is an administrative default — it does not certify that section 16 conditions are met.
• Pending records stay out of GSTR-2B. A pending item is not a claim; if it is still pending when the October return is filed, the FY 2025-26 credit is lost.
• Rejected credit notes affect the supplier's output tax adjustment, so align with the vendor before rejecting.
• Since GSTN's October 2025 IMS update, credit notes (and downward amendments of documents) can also be kept pending — but only for one tax period. The same update lets the recipient enter the actual ITC reversal amount when accepting a credit note, rather than reversing the full tax shown.

Keep the IMS action log and a downloaded copy of the GSTR-2B you relied on for each period. These are the documents an officer will ask for in an ITC mismatch notice.

Other rules that interact with 30 November

Rule 37A — supplier has not filed GSTR-3B

If a supplier reported the invoice in GSTR-1 but did not file the matching GSTR-3B by 30 September 2026, Rule 37A requires the recipient to reverse that FY 2025-26 credit in a GSTR-3B filed on or before 30 November 2026, with interest where applicable. It can be re-claimed after the supplier files. Check the "supplier GSTR-3B status" report on the portal before the October return.

Rule 37 — 180-day payment condition

Under the second proviso to section 16(2) read with Rule 37, credit must be reversed if the supplier is not paid within 180 days of the invoice date, and can be re-availed on payment. This re-availment is not hit by section 16(4). But a credit that was never originally claimed before 30 November cannot be "re-availed" later — it is simply time-barred.

Credit notes and the supplier's deadline

Section 34 applies the same 30 November limit to suppliers issuing credit notes for FY 2025-26 supplies. Expect a rush of credit notes in November; each one reduces your eligible ITC and must be matched to the original invoice.

Common credit (Rules 42 and 43)

If inputs or capital goods are used for both taxable and exempt supplies, the annual true-up for FY 2025-26 should be completed alongside the ITC close-out, not after GSTR-9 is filed.

Sections 16(5) and 16(6) are not a general waiver

Sections 16(5) and 16(6), inserted by the Finance (No. 2) Act 2024 and explained in CBIC Circular 237/31/2024-GST, relax the time limit only for FY 2017-18 to FY 2020-21 and for certain cases of registration revocation. They do not help FY 2025-26 claims.

FY 2025-26 ITC close-out checklist

Run this at GSTIN level and document level — not on consolidated totals.

A worked example

The ₹2,05,000 mismatch is not "recoverable" until the supplier corrects it in time for the October GSTR-2B. If the correction arrives later, that credit is gone.

Weekly exception review in November

Hold a short weekly meeting and sort every open item into one of four buckets: actioned and verified, waiting for vendor, eligibility disputed, or time-barred. Keep rejected and unresolved items with the reason recorded, along with portal downloads, acknowledgements and the final GSTR-3B working. A signed exception register is the best defence when an ITC mismatch notice arrives.

What 30 November 2026 does not mean

• It is not an extension of any GSTR-3B or GSTR-9 due date.
• It does not allow credit without receipt of goods or services.
• It does not make blocked credits eligible.
• It does not guarantee that a late supplier upload will reach a GSTR-2B in time.
• It does not override an earlier GSTR-9 filing date.

How GSTCPC handles the FY 2025-26 ITC close-out

GSTCPC is Figment's GST compliance software for enterprises and CA firms. For a year-end ITC review, the relevant features are:

• GSTR-2B/2A reconciliation of the purchase register at invoice level, showing matched, mismatched and missing invoices for each GSTIN, with AI-assisted match suggestions.
• IMS actions — accept, reject or pending — recorded against the purchase register before records reach GSTR-2B.
• ITC tracking and mismatch reports before GSTR-3B is filed, plus a temporary reversal and reclaim ledger for Rule 37 and Rule 37A movements.
• Vendor follow-up, so discrepancies and reminders go to suppliers from one place.
• Multi-GSTIN management with consolidated and state-wise reports, and maker-checker access controls for preparing, reviewing and filing GSTR-3B and GSTR-9.

To check that supplier GSTINs are active before chasing them, the GST Verification API validates registrations in bulk. For a quick estimate of eligible credit, try the free GST ITC calculator. If an ITC mismatch notice does arrive later, NoticeCPC helps track it to closure.

Key takeaways

• The GST ITC deadline for FY 2025-26 is 30 November 2026, or the GSTR-9 filing date if earlier.
• For monthly filers, the October 2026 GSTR-3B filed by 30 November is the last return that can carry it; for QRMP filers, it is the July–September 2026 return.
• Supplier uploads must land before the October GSTR-2B cut-off in mid-November.
• Treat Rule 37A, Rule 37, credit notes and blocked credits as separate tests.
• Reconcile at GSTIN and document level, and keep a signed exception register.
