ITC Time Limit 30 November 2026: Claim FY 2025-26 Credit Before It Lapses

The rule: under section 16(4) of the CGST Act, input tax credit on an invoice or debit note of a financial year can be claimed only up to 30 November of the next financial year, or the date you file the annual return for that year, whichever is earlier. For FY 2025-26 (April 2025 to March 2026), the cut-off is 30 November 2026 — unless you file GSTR-9 for FY 2025-26 before that, in which case the earlier date applies.

Which return is your last chance: credit is claimed through GSTR-3B, so the deadline really means "the GSTR-3B filed on or before 30 November 2026". For monthly filers that is the October 2026 GSTR-3B, due 20 November 2026. For quarterly (QRMP) filers, the July–September 2026 return, due in late October, is the practical last return — the October–December return falls due after 30 November.

What gets missed most: purchase invoices uploaded late by suppliers, bills booked in your accounts but never claimed in GSTR-3B, debit notes, import IGST where the bill of entry did not reflect in GSTR-2B on time, and ITC you reversed earlier for a temporary reason (such as the 180-day payment rule) and forgot to reclaim. Each of these is still recoverable before the cut-off — and lost after it.

Step 1 — reconcile FY 2025-26 purchases with GSTR-2B: download GSTR-2B for April 2025 to March 2026 (and later months, because some supplier invoices appear late), match them line by line with your purchase register in Tally or Zoho, and list invoices that are in your books but not yet claimed.

Step 2 — chase suppliers: for invoices missing in GSTR-2B, send suppliers a list of invoice numbers and amounts now. Suppliers can upload or amend FY 2025-26 invoices and credit notes in GSTR-1 only up to 30 November 2026 as well, so every week of delay shortens their window too.

Step 3 — check IMS: invoices sit in the Invoice Management System as accepted, rejected or pending. Pending invoices can roll into later GSTR-2B statements; make sure nothing you are entitled to has been left pending or rejected by mistake before the October return.

Step 4 — Rule 37A reversal: if a supplier collected GST from you but did not file GSTR-3B for that period by 30 September 2026, Rule 37A requires you to reverse that ITC in a return filed by 30 November 2026. You can re-claim it later once the supplier files. Ignoring it usually comes back as a DRC-01C or a scrutiny notice.

Step 5 — claim and document: add the unclaimed eligible ITC in table 4 of the October 2026 GSTR-3B (or your last eligible return), keep a workpaper listing invoice-wise what was claimed and why, and do not claim blocked credits under section 17(5) just because the deadline is near.

Not sure how much credit is sitting unclaimed? A one-time FY 2025-26 ITC reconciliation is usually done in a few days. VedhaNirvana Accounting India is a CA-led firm, Chennai HQ, serving SMEs across India — WhatsApp your GSTIN and software for a written quote before the cut-off.
