In a welcome move for taxpayers, the Goods and Services Tax Network (GSTN) has extended the GSTR-3B Return Filing Last Date for October 2025 (for the tax period of September 2025) from October 20, 2025, to October 25, 2025.
This decision has been made in light of the upcoming festive season, as multiple holidays across India could disrupt normal business operations and compliance activities. The five-day extension ensures that taxpayers have sufficient time to accurately prepare and submit their monthly GST returns without facing penalties or late fees.
Reason Behind the Extension
The extension of the GSTR-3B Return Filing Last Date in October comes as a result of the nationwide festive holidays and the corresponding increase in portal activity during the period.
The GSTN decided to offer this relief to promote ease of compliance, particularly for small and medium-sized businesses (SMEs) that manage multiple tax filings each month.
The extension aims to:
-
Reduce last-minute filing pressure
-
Prevent technical glitches due to high portal traffic
-
Ensure accurate return filing and reconciliation of Input Tax Credit (ITC)
This thoughtful measure aligns with the government’s ongoing efforts to simplify GST compliance and improve the taxpayer experience.

Advisory for Taxpayers
Although the GSTR-3B Return Filing Last Date October has been extended, taxpayers are advised not to wait until the final day to submit returns. The GSTN portal typically experiences heavy traffic during the last 48 hours, which may lead to slower performance or delays.
It’s best to complete filings well in advance to:
-
Avoid portal congestion
-
Prevent interest or penalty charges due to missed timelines
-
Maintain an excellent compliance record
The GSTN continues to offer both online and offline tools to simplify return preparation and submission.
The GSTR-3B Return Filing Last Date October Extension to October 25, 2025, is a practical and considerate decision by the Goods and Services Tax Network (GSTN).
It supports businesses during the festive season while ensuring continued compliance under the Goods and Services Tax (GST) framework.
Taxpayers should utilize this extended window to file accurately and avoid last-minute stress or penalties.
This update reinforces the government’s vision of promoting “Ease of Doing Business” through flexibility and taxpayer-friendly initiatives.
