Time-limit extension for GST return filing: revised submission windows for GSTR-1, GSTR-2 and GSTR-3 established. Extension of statutory filing deadlines for GST returns is authorised under the Telangana GST Act by a Commissioner's notification on Council recommendation, superseding earlier notifications. The notification sets revised submission windows for FORM GSTR-1, FORM GSTR-2 and FORM GSTR-3 for July and August 2017, allocating specific final dates or date ranges for each form and month and thereby consolidating the revised schedule for furnishing the specified details or returns.
