The video discusses the significant changes being introduced to the GST return filing system, effective from October 2025. Key updates include: GSTR 1 and GSTR 3B Integration: Sales data reported in GSTR 1 will now automatically flow into GSTR 3B and be non-editable. Any required corrections must be made in GSTR 1 or GSTR 1A before filing GSTR 3B [00:27]. Invoice Management System (IMS): Changes have been made to the system for taking action (Accept/Reject/Pending) on inward supplies. Your actions in the IMS will directly impact the GSTR 2B generation and the Input Tax Credit (ITC) flow to GSTR 3B. If no action is taken, it will result in deemed acceptance [02:09]. The system now supports bulk actions on up to 100 invoices per page [02:45]. Credit Note Handling: A new 'Pending' tab is introduced, and a facility is added to allow taxpayers to specify the exact amount of ITC reversal for credit notes based on the ITC actually claimed [03:27]. GSTR 7 (TDS Return): The return will now require invoice-wise reporting for TDS [04:19]. GST Annual Return (GSTR 9): The filing deadline for Financial Year 2024-25 is December 31, 2025. GSTR 9 is not mandatory for taxpayers with an aggregate annual turnover up to ₹2 Crores [05:48]. GSTR 9 will also auto-populate figures in Tables 6 and 7, and reconciliation of ITC as per GSTR 2B will be required in Table 8 [06:07]. Important Deadlines: Taxpayers must check the GST portal for notices for FY 2021-22 (Sec 73) and FY 2019-20 (Sec 74) by September 30. Furthermore, filing for all pending GSTR 1, GSTR 3B, GSTR 4, and GSTR 9C for FY 2021-22 and prior periods must be completed by October 31, 2025, as filing for past 3 years will be blocked from November 1, 2025 [07:41]. #GST #GSTReturnFiling #GSTR3B #GSTR1 #GSTR7 #NewGSTChange #GSTUpdate #InvoiceManagementSystem #IMS #GSTR2B #ITC #CreditNoteGST #GSTR9 #GSTAnnualReturn #GSTNotice #GSTFilingDeadline #CASatbirSingh #GSTNews2025 #GSTIndia #FinanceNews GST, GST Return Filing System, GSTR 3B, GSTR 1, GSTR 1A, GSTR 7, New GST Change, GST News, GST Update October 2025, Invoice Management System, IMS, GSTR 2B, Input Tax Credit, ITC, Credit Note GST, GST TDS, GSTR 9, GST Annual Return, GSTR 9 exemption, GST Notice, GST Reconciliation, CA Satbir Singh, GST filing deadline, non-editable GSTR 3B, auto-population GSTR 3B, GST rule changes, GST latest news 2025
