BCAS Requests Extension of GSTR-3B Filing Deadline for September 2025 Amid Diwali Festivities

GSTR-3B is a monthly self-declaration return form under the Goods and Services Tax (GST) system. Registered taxpayers use this form to declare their summary of outward supplies, inward supplies, input tax credit (ITC) claimed, and the taxes paid. This return needs to be filed on the 20th, 22nd, and 24th of each month based on different categories of taxpayers. It was already expected that an extension to the due date of GSTR-3B return filing would be granted, as festival dates and return filing dates were overlapping each other, hence creating problems in compliance. Like this year, Diwali is falling on two days, i.e., October 20 and 21, 2025. Meaning, people nationwide will celebrate this festival on both dates, some on the 20th and some on the 21st, and the legal deadlines for filing Form GSTR-3B were October 20, 22, and 24, 2025, which clashed with each other. Therefore, the government has taken his major step.
