<h1>Central GST rate cuts for solar, wind, EV buses and biodegradable bags to lower project and vehicle costs</h1> A central government GST overhaul reduces rates on solar panels, wind turbines, related devices, effluent treatment services and biodegradable bags, and cuts GST on passenger and commercial buses from 28% to 18%, aiming to lower project and vehicle costs, incentivise renewable deployment, centralised waste management and fleet modernisation while supporting domestic manufacturing and fiscal balance. Legally, the changes alter indirect tax liabilities for manufacturers, service providers and transport operators, affect ongoing compliance and invoicing obligations, and may prompt administrative guidance on classification, transitional relief and revenue-sharing arrangements between central and state authorities.
