GST 2.0 India: New Tax Slabs and e-Invoicing Rules Explained (April 2026)

What Is GST 2.0 and Why Does It Matter?

India’s Goods and Services Tax regime has undergone its most significant overhaul since the landmark 2017 rollout. Dubbed GST 2.0 by industry observers and policy analysts, the April 2026 reforms compress the existing four-slab structure into a leaner three-tier system, while simultaneously making e-invoicing mandatory for a much wider category of businesses. If you run a business, work as a freelancer, or manage finances for an SME, these changes affect your cash flow, compliance calendar, and monthly filings starting April 1, 2026.

The GST Council’s rationale is straightforward: reduce classification disputes, eliminate rate inversion anomalies, and bring India’s indirect tax framework closer to global best practices. The old system — with its 5%, 12%, 18%, and 28% slabs — created rampant confusion around which rate applied to composite supplies, digital services, and bundled products. GST 2.0 collapses the 12% slab, redistributes goods, and introduces a new 40% cess band for ultra-luxury and sin goods.

The New Three-Slab Structure Explained

Under GST 2.0, the rate architecture looks like this:

The elimination of the 12% slab is the headline change. Goods and services that previously attracted 12% GST — including processed foods, certain pharma products, non-AC hotel rooms below ₹7,500, and business-class air travel on domestic routes — now move to either 5% (for essentials) or 18% (for standard goods), depending on their classification under the revised schedule.
