1. Rate Rationalisation — The New GST Slabs (w.e.f. 22 Sep 2025)
The 56th GST Council meeting (3 Sep 2025), chaired by Finance Minister Nirmala Sitharaman, approved a historic simplification of GST rates. The old multi-slab structure has been replaced:
| Old Slab | New Position | Impact on Your Business |
|---|---|---|
| 0% (Exempt) | 0% (Retained) | Essentials — food, health, education remain exempt |
| 5% | 5% (Retained) | Basic goods, essential services |
| 12% | Merged into 5% or 18% | Check your HSN code — most items reclassified |
| 18% | 18% (Main Slab) | Most goods and services now fall here |
| 28% | Merged into 18% or 40% | Reduced for many; only true luxury stays at 40% |
| — | 40% (New Slab) | Sin goods: tobacco, luxury cars, high-end goods |
Important relief: Individual life and health insurance premiums are now fully exempt from GST — a major benefit for policyholders and businesses buying group health cover.
2. Invoice Management System (IMS) — Mandatory from 1 October 2025
This is the single biggest compliance change under GST 2.0. The IMS fundamentally changes how Input Tax Credit (ITC) is claimed — and businesses that miss this are losing ITC worth lakhs.
- Old process: GSTR-2B was auto-populated and ITC was auto-credited to GSTR-3B. Minimal action required from recipient.
- New process: Every invoice uploaded by your supplier appears in your IMS dashboard. You must manually Accept, Reject, or Keep Pending each invoice before ITC flows to GSTR-3B.
- Rejected invoices = No ITC. If you reject an invoice in IMS, that credit is gone for that period. No reversal possible.
- Credit Notes: From 1 Oct 2025, a supplier can only reduce their tax liability via credit note if the recipient has reversed the corresponding ITC — now a legal requirement under amended Section 34(2) of the CGST Act.
3. GSTR-3B Hard-Locked — No Manual Editing
From October 2025, tax liability fields in GSTR-3B are system-generated and hard-locked. Manual editing of outward tax liability is no longer permitted. The system calculates liability directly from your GSTR-1/IFF data. This means your GSTR-1 must be 100% accurate before filing — there is no room to fix errors in GSTR-3B anymore.
4. GSTAT — GST Appellate Tribunal Launched
On 24 September 2025, the GST Appellate Tribunal (GSTAT) was officially launched in New Delhi — a landmark development providing a dedicated forum for resolving GST disputes. Key features:
- Digital-first institution — filings and hearings available online
- Plain-language decisions to improve accessibility for MSMEs
- Mandatory pre-deposit for appeals: 10% of tax demand
- Expected to drastically reduce the backlog of GST disputes across India
5. Annual Return (GSTR-9/9C) — FY 2024-25 Updates
The GSTN has released new advisories for GSTR-9 and GSTR-9C for FY 2024-25 covering new ITC disclosure requirements. The system now auto-calculates late fees that increase daily, and the portal will not allow filing of current year returns if prior year annual returns are pending.
