Noteworthy Points for GST Returns for November 2025, Considering the Time Limit for Adjustments for FY 2024-25

As businesses prepare their GST returns for November 2025, this month is critical since this is the last month in which corrections, eligible Input Tax Credit (ITC) can be claimed for previous financial year i.e. FY 2024-25. Under GST law, the due date of filing the GSTR-3B for November (generally 20th December) is the cut-off for rectifications relating to the previous financial year.

Below are the key points taxpayers should keep in mind while filing GST returns :

1. Final Opportunity to Claim ITC for FY 2024-25

As per Section 16(4) of the CGST Act, businesses must claim pending ITC related to FY 2024-25 on or before the filing deadline of the November 2025 GSTR-3B.
Ensure the following:

• All invoices and debit notes issued in FY 2024-25 are recorded.
• Suppliers have filed their returns so that ITC reflects in GSTR-2B.
• No ITC remains unclaimed due to clerical or accounting delays.

Important: Any ITC not claimed within this timeline will lapse and cannot be availed later.

• Rectification of Errors in FY 2024-25 Returns

This is the last window to:

• Rectify incorrect tax rates or classifications
• Correct turnover reporting
• Amend outward supply details
• Fix mismatches between books and GSTR-1/GSTR-3B
• Reconciliation between Books, GSTR-1, and GSTR-3B

A full year-end reconciliation should be completed before the November return:

• Match outward supplies as per books with GSTR-1
• Ensure tax amounts declared match GSTR-3B
• Verify whether all credit notes, debit notes, and adjustments are fully accounted for
• Identify discrepancies in tax liability or ITC

This prevents future notices and demand orders due to mismatched reporting.

• Review of GSTR-2B and Supplier Compliance

Since ITC is restricted to the amount reflecting in GSTR-2B, ensure that:

• All suppliers have filed their GSTR-1 for March 2025 – November 2025
• Follow up with non-compliant vendors
• Reconcile each invoice with GSTR-2B
• Adjustments for Credit Notes Related to FY 2024-25

Credit notes pertaining to FY 2024-25 must be reported by 30 November 2025 return or date of furnishing annual return whichever is earlier, any credit note issued thereafter will not be allowed to be offset against output tax liability

Reverse Charge Mechanism (RCM) Review

Ensure all FY 2024-25 RCM liabilities are:

• Fully accounted for
• Paid in cash
• ITC claimed (within the time limit)
• Annual Turnover Review and Compliance Readiness

Before the adjustment deadline:

• Check if turnover has crossed any registration or audit threshold
• Review if e-invoice/e-way bill applicability thresholds have been triggered
• Prepare documentation for annual return (GSTR-9) and audit, if applicable
• Ensure consistency between the annual return and monthly returns

The November 2025 GST return is a critical compliance event for all businesses, as it is the final chance to claim, and reconcile transactions related to FY 2024-25. A meticulous review of returns, ledgers, ITC eligibility, and supplier compliance will help avoid future disputes, penalties, and loss of credit. Timely action today ensures a clean and accurate GST record for the financial year.
