The EV board approved in principle on 10 September 2026 a new excise tax structure: imported EVs without a Thai plant pay more, while makers that invest locally and use more Thai-made parts pay less. Four rate tiers are planned, but the article gives no rates or start date yet. If you sell, import, or service EVs or EV parts, hold off on big import or pricing decisions until the rates are published. Charging-station and used-battery rules are also being drafted.
