(MENAFN- Live Mint) The Central Board of Indirect Taxes and Customs (CBIC) has extended the due date for filing GSTR-3B for the month of September and July to September quarter to October 25, 2025.

The deadline extension comes after a group of chartered accountants requested that the central government extend the GSTR-3B filing deadline, which was initially set on October 20. They cited a clash with Diwali as the reason for the request.

Request for deadline extension

The Bombay Chartered Accountant Society (BCAS) told the Ministry of Finance that the deadline for GSTR-3B filing is October 20, which coincides with a holiday due to Diwali. The BCAS highlighted that the days before Diwali are usually public holidays in several regions across India, and also include a Sunday.

The body said,“Therefore, as a significant step towards ease of doing business, it is earnestly requested that the due date for filing GSTR-3B of September 2025 be extended."

It further added,“Granting this essential administrative relief will enable registered persons and tax practitioners to complete the necessary compliance procedures following the conclusion of the festival period, ensuring accurate and complete return filing and promoting adherence to the provisions of the CGST Act without penalising taxpayers for unavoidable circumstances.”
