Government Extends GSTR-3B Filing Deadline to October 25, 2025

The government on October 19 announced a five-day extension for filing the monthly GSTR-3B tax payment form. The new due date for taxpayers is now October 25, 2025. This extension applies to both September monthly returns and the July-September quarterly filings.

CBIC Notification

The Central Board of Indirect Taxes and Customs (CBIC) issued the notification confirming the extension. In a post on X (formerly Twitter), CBIC stated, “@cbic_india extends the GSTR-3B filing deadline.” Taxpayers are now allowed to submit their returns and pay taxes without any late fees until the revised date.

About GSTR-3B

GSTR-3B is a summary return filed by registered taxpayers on a monthly or quarterly basis. The form consolidates details of sales, purchases, input tax credit, and tax liabilities. Different categories of taxpayers normally file GSTR-3B between the 20th, 22nd, and 24th of each month, depending on the type and size of their business.

Reason for Extension

The extension was widely expected, as October 20 coincides with Diwali, one of India’s major festivals. The move allows taxpayers to complete their filings without the pressure of the holiday schedule, ensuring compliance while accommodating festive observances.
