Thailand Slaps 35% Excise Tax on Imported EVs from 2027

Thailand's Cabinet has approved a 35% excise tax on imported battery electric vehicles (BEVs) and range-extended electric vehicles (REEVs), effective 1 January 2027. The levy gives import-reliant OEMs and their suppliers roughly 15 months to localise assembly or absorb a substantial cost penalty in Southeast Asia's largest vehicle production base.

The decision implements resolutions passed by the National Electric Vehicle Policy Committee on 25 November 2025 and 10 September 2026. According to a translated version of the official press statement, the committee instructed the Excise Department (Thailand's revenue agency for vehicle and consumption taxes) to formulate policies stimulating domestic vehicle manufacturing and parts assembly.

What does the tax change for producers?

Deputy Prime Minister and Minister of Finance Ekniti Nitithanprapas framed the restructuring as a competitive equaliser. He explained that it counters competition from imported models excluded from state incentive schemes, thereby equalising market conditions for local producers.

That points directly at brands shipping fully built EVs into Thailand without local manufacturing commitments. For them, the 35% duty stacks on top of existing import costs from the start of 2027. For OEMs already assembling in Thailand — and the tier-one parts makers around Rayong and the Eastern Economic Corridor — the measure protects domestic volumes and pulls demand toward locally built models.

Beyond local assembly, the government expects the fiscal adjustment to sustain wider employment, skills development, and automotive supply chains. The strategy rests on three stated principles: "Investment-Driven Import," "Regional and Global EV Hub," and "High Value-Added Local Content." These pillars underpin Thailand's shift from conventional vehicle manufacturing toward eco-friendly vehicle exports via a "Multi-Pathway" alternative-energy approach.

A BEV-led market recovery

The tax lands on a market already tilting sharply toward electrification. Federation of Thai Industries data show new vehicle sales rose by more than 14% year-on-year to 55,255 units in September 2026, following growth of 24% to 48,350 units a year earlier.

• BEV sales increased by 90% year on year to 22,587 units.
• Pickup-truck sales declined by more than 7% to 10,315 units.
• The market recovered despite widespread flooding across the country, including large parts of Bangkok, caused by heavy monsoonal rains.

The nine-month picture confirms the trend. Thailand's domestic vehicle market expanded by 16% to 521,225 units in the first nine months of 2026, up from 447,969 units a year earlier.

What to watch next

The near-doubling of BEV demand explains Bangkok's urgency: every imported unit sold today is volume that local plants and parts suppliers are not capturing. The 35% rate, once effective, will reprice those imports overnight.

Watch three things. First, the formal implementing regulations from the Excise Department, which will define exactly which vehicles and value thresholds qualify as "imported." Second, new or accelerated localisation announcements from Chinese and other EV brands racing to beat the 1 January 2027 deadline. Third, whether the BEV sales surge holds once incentive-excluded imports lose their price advantage — the real test of whether the "High Value-Added Local Content" principle converts policy into plant-floor investment.
