<h1>Tax authority extends July GSTR-3B filing deadline to August 27, 2025 for taxpayers in five rain-affected districts</h1> A central tax authority has extended the due date for filing the July GSTR-3B monthly summary return to August 27, 2025, for registered taxpayers whose principal place of business is in five rain-affected districts of the Mumbai region: Mumbai City, Mumbai Suburban, Thane, Raigad, and Palghar. The relief responds to severe rains and disruption of public life and is intended to prevent late fees and penalties for affected taxpayers who file within the extended deadline. Taxpayers are advised to use the extension and submit returns by the new date.
