<h1>GST rate rationalisation: new central tax slabs require matching state notifications and industry implementation to pass benefits.</h1> Centre has notified Central GST rates effective from September 22, requiring states to notify corresponding SGST rates. The notification implements a two-tier structure for most supplies while preserving a top-rate category and a cess on tobacco and related products; GST revenues remain shared equally between Centre and states. Businesses must update systems, pricing and supply chains to implement the revised rates and ensure transparent pass-through of benefits to consumers.
