Introduction
The period from 2025 to early 2026 has been transformative for India's GST framework. From the landmark rate rationalization at the 56th GST Council Meeting to stricter e-invoicing mandates, the launch of GSTAT, and new compliance rules effective January 2026, businesses must stay updated to remain compliant.
GST Rate Rationalization — The Biggest Reform Since 2017
Effective September 22, 2025, the GST slab structure was simplified from six tiers to five. The 12% and 28% slabs were eliminated, affecting over 200 items.
| GST Slab | Purpose |
|---|---|
| 0% (Nil) | Essential goods and services |
| 3% | Gold and silver (unchanged) |
| 5% | Merit rate for essentials |
| 18% | Standard rate for most goods and services |
| 40% | Demerit rate for luxury/sin goods |
E-Invoicing — Threshold Lowered to ₹5 Crore
Key changes effective from April 2025 onward:
- E-invoicing threshold reduced to ₹5 crore, bringing significantly more SMEs under the mandate
- Businesses with ₹10 crore+ turnover must upload invoices within 30 days
- Credit note e-invoicing is now mandatory
GSTAT — GST Appellate Tribunal Now Live
A major milestone in 2026: the GST Appellate Tribunal (GSTAT) was formally launched on February 16, 2026. This provides businesses a long-awaited appellate mechanism for GST disputes.
Conclusion
2025-26 marks a watershed period for GST in India. Businesses — especially MSMEs — should conduct internal audits and work with their tax advisors to navigate these changes smoothly.
