Following the 56th GST Council's landmark decision on September 3, detailed analysis reveals the two-slab GST structure will transform India's indirect tax landscape from September 22, 2025. Items previously at 12% will mostly move to 5% (essentials) or 18% (non-essentials), while 28% items shift to 18% except sin goods at 40%. Key beneficiaries include processed foods, dry fruits, dairy products, packaged snacks, refrigerators, washing machines, ACs, automobiles, and tractors. The reform is expected to boost consumption, simplify compliance for businesses, and reduce cascading effects. The average GST incidence may drop from 11.5% to below 10%. CBIC will issue formal notifications on September 17 for the transition.
