<h1>GST Council Proposes Raising Peak Tax Rate to 20% in Model Bill, Allowing Future Changes Without Parliament Approval.</h1> The GST Council has proposed increasing the peak tax rate to 20% from the current 14% in the model GST Bill, allowing future rate changes without needing parliamentary approval. This adjustment does not alter the existing 4-slab rate structure of 5%, 12%, 18%, and 28%. The change is intended to provide flexibility for potential future rate hikes. The central and state GST rates could each reach up to 20%, allowing a maximum combined levy of 40%. The Central GST Bill is set for introduction in Parliament, with a planned GST rollout from July 1.
