Thailand’s Excise Department Proposes Overhaul of Vehicle Tax Structure
The Thai Excise Department is planning to restructure vehicle taxation by prioritizing CO2 emissions as the primary index to support the transition to electric vehicles.
According to a report by Thai Post on August 31, 2026, Thailand’s Excise Department is initiating a significant restructuring of the national vehicle tax system. The proposed changes aim to adapt to the evolving automotive industry, with officials planning to utilize carbon dioxide (CO2) emissions as the primary index for determining tax rates.
This policy shift is designed to incentivize the adoption of electric vehicles (EVs) while simultaneously mitigating the economic impact on manufacturers of internal combustion engine vehicles. The department intends to present this proposal to the National EV Policy Committee before submitting it to the Cabinet for formal consideration.
For residents and expatriates in Thailand, this development is noteworthy as it could eventually influence the purchase price and availability of various vehicle models in the local market. As the government seeks to align its tax framework with environmental goals, consumers may see a shift in the cost-benefit analysis between traditional and electric transport options. At this stage, the proposal remains in the planning phase. It is not yet confirmed when the new tax structure will be finalized, what the specific CO2 thresholds will be, or when these changes might be implemented for the general public.
