<h1>Opposition states reject GST rate rationalisation, demand compensation via additional sin and luxury duty, five-year revenue protection</h1> Opposition-ruled states oppose the Centre's proposed GST rate rationalisation, asserting it could reduce state GST revenues by about 15-20% (Rs 1.5 lakh crore to Rs 2 lakh crore) and demanding compensation. They will present to the GST Council a proposal to offset revenue loss by imposing an additional duty on sin and luxury goods, distributing those proceeds to states, fixing 2024-25 as the base year for revenue protection, providing five years of compensation until revenues stabilise, establishing profiteering detection, and, if deficits persist, allowing the Union to raise loans secured by future receipts from the additional levy.
