GST Due Dates November 2026: GSTR-1, GSTR-3B, IFF and ITC Deadline
All GST due dates in November 2026 for the October 2026 period — GSTR-7, GSTR-8, GSTR-1, IFF, GSTR-3B, PMT-06 — plus the 30 November ITC and GSTR-1 amendment deadline for FY 2025-26.
November is a heavier GST month than usual: the regular October 2026 returns fall due, and 30 November 2026 is also the last date for several FY 2025-26 actions. With Diwali in the first half of the month, plan document cut-offs early. Dates below are the standard statutory dates; always check the portal for any extension notified by CBIC.
10 November 2026 — GSTR-7 (TDS deductors under GST) and GSTR-8 (e-commerce operators collecting TCS) for October 2026.
11 November 2026 — GSTR-1 for October 2026 for monthly filers. File this first: your customers' GSTR-2B and your own GSTR-3B liability depend on it.
13 November 2026 — IFF (Invoice Furnishing Facility) for October 2026 for QRMP taxpayers who want B2B invoices to reach their customers monthly. Also GSTR-5 (non-resident taxpayers) and GSTR-6 (input service distributors).
20 November 2026 — GSTR-3B for October 2026 for monthly filers. This is also the last monthly GSTR-3B in which most businesses can claim FY 2025-26 input tax credit before the 30 November cut-off.
25 November 2026 — PMT-06 tax payment for October 2026 for QRMP taxpayers (the first month of the October–December quarter).
30 November 2026 — last date to claim FY 2025-26 ITC under section 16(4) (or the date of filing GSTR-9, if earlier); last date for suppliers to declare FY 2025-26 credit notes and amend FY 2025-26 invoices in GSTR-1; and the outer date to reverse ITC under Rule 37A where your supplier did not file GSTR-3B by 30 September 2026.
Late fees if you miss: GSTR-3B and GSTR-1 attract a late fee of ₹50 per day (₹20 per day for nil returns), capped by turnover, plus 18% annual interest on tax paid late. Two missed GSTR-3B periods in a row can block e-way bill generation.
A simple November plan: freeze October purchase bills by 5 November, reconcile GSTR-2B and the FY 2025-26 ITC position in the second week, file GSTR-1 by the 11th and GSTR-3B a few days before the 20th.
