Thailand's auto industry supports a proposed restructuring of excise tax on electric vehicles to level the playing field between domestic and imported EVs, but urgently requests a clear 6-month implementation timeline to avoid cost disruptions. The Ministry of Finance is considering a phased tax increase (potentially from 10% to 32% on imported EVs) to incentivize local EV manufacturing. Industry leaders warn that hasty implementation without proper notice could disrupt existing customer orders and business planning, and propose a stepped tax approach tied to local content value, production volume, exports, and investment metrics.
