New 5% & 18% GST Slabs To Take Effect From Sept 22

The new GST slab structure, reducing four slabs to two effective rates of 5% and 18%, plus a 40% rate for sin or luxury goods—will be implemented across India starting September 22, 2025, coinciding with Navratri. Most goods and services will transition then, though tobacco and related items will await a later rollout.
