The Goods and Services Tax Network portal has displayed a new due date of October 25, 2025, for filing GSTR-3B, the monthly return form used by registered taxpayers to report outward supplies, input tax credit, and tax liabilities. The updated due date appeared on the official GST portal under the “Monthly Return – GSTR-3B” section on October 17, 2025.

Ordinarily, the due date for filing GSTR-3B is the 20th of every month for most taxpayers. The form is a crucial compliance requirement under the GST framework, facilitating timely tax payment and reconciliation of credits between suppliers and recipients.

However, despite the change being visible on the portal, no official notification or circular has been issued by the Central Board of Indirect Taxes and Customs (CBIC) or the GST Council confirming any extension of the filing deadline.
