Thailand Plans EV Excise Tax of About 30% to Push Importers Toward Local Production

Imported EVs face a bigger tax bill from 2027

Thailand's Finance Ministry is preparing an excise tax of about 30% or more for fully imported electric vehicles, targeting companies that sell finished cars without investing in Thai production. The proposed starting date is January 1, 2027. For a vehicle valued at 1 million baht, an increase from 10% to 30% would add about 200,000 baht in excise tax under the ministry's illustrative calculation.

The proposal follows a September 10, 2026, resolution by the National Electric Vehicle Policy Committee, known as the EV Board. The Cabinet subsequently acknowledged the board's direction and instructed the Excise Department to prepare detailed changes for Cabinet approval. The final rates, eligibility rules and treatment of existing orders still require that approval.

Finance Minister and Deputy Prime Minister Ekniti Nitithanprapas has indicated a rate around 30%, while a Finance Ministry source described the highest rate as at least 30%. A private sector proposal considered earlier put the range at 31% to 39%. Ekniti said discussions with the automotive industry would determine the final figure.

The central aim is to turn Thailand's growing appetite for electric cars into more factory investment, locally produced components and employment. Qualifying vehicles made in Thailand would remain outside the proposed increase aimed at fully imported EVs.

The pressure comes as electric vehicles become a much larger part of the market. Federation of Thai Industries figures put battery electric vehicles at 30.88% of domestic vehicle sales in January through July 2026, while 63% of BEVs were imported. Officials want more of that demand supplied by factories inside Thailand.

How much could buyers pay?

Electric passenger vehicles outside preferential arrangements currently face an excise rate of about 10%. Vehicles meeting specified conditions can qualify for a reduced rate of 2%. The planned increase targets the higher import category rather than replacing every EV's existing tax rate with 30%.

Excise is a tax charged on particular goods. Customs duty is a separate charge associated with bringing goods across a border. Both can affect vehicle prices, alongside other taxes, distribution costs and the manufacturer's pricing decisions.

The ministry's example uses a vehicle valued at 1 million baht. At 10%, its excise tax would be about 100,000 baht; at 30%, it would be about 300,000 baht. That is an increase of 20 percentage points and three times the earlier tax amount. The eventual showroom price would depend on the final calculation rules and how much of the added cost a company passes to buyers.

An exemption allowing vehicles ordered before the change to retain the previous rate has also been discussed. Buyers would need the approved rules to know which order dates and documents qualify. A purchase contract, import date and vehicle delivery can occur at different times, making the transition rules financially important.

Three tax levels would reward production in Thailand

The proposed structure would place companies in different tax bands according to their manufacturing investment and use of Thai components. A factory alone would not necessarily secure the lowest rate: the amount and value of production inside Thailand would also matter.

The broad design has three levels:

• The lowest rate for manufacturers with Thai factories that use substantial domestic content or make important EV components locally. Preliminary guidance puts this range at approximately 1% to 6%, depending on the vehicle and qualifying conditions.
• A middle rate for businesses with some domestic investment but greater dependence on imported vehicles or components. Rates above 10% have been discussed for some arrangements.
• The highest rate, approximately 30% or more, for businesses importing finished EVs for sale without a Thai production base.

Excise Department Director General Pornchai Thiravej has indicated that the highest band would receive priority. Officials were working toward submitting details to the Cabinet during September 2026.

Manufacturers with Thai factories could also receive permission to import certain models for market testing, subject to quotas. The proposed quota calculation would consider the previous year's domestic investment, including the value of Thai components used and employment. That would give companies a route to introduce models before producing them locally, while tying import privileges to economic activity in Thailand.

What would count as Made in Thailand?

The Finance Ministry also wants to change how domestic content is measured under the Made in Thailand standard. The proposed approach would give greater weight to valuable technology components produced locally, instead of relying as heavily on profits, wages and electricity expenses in the calculation.

Local content means the share of a vehicle's value attributed to production inside the country. A vehicle assembled in Thailand can still contain many imported parts. Changing which costs count could therefore change a manufacturer's tax position even if its assembly plant stays in the same place.

Existing Board of Investment incentives already require Made in Thailand certification for additional local content benefits. The stated minimums are 40% for battery electric vehicles and 45% for plug-in hybrids. During discussions before the September 10 meeting, officials were considering either moving a 40% domestic share toward 50% or tightening the calculation itself.

The earlier government framework shows how detailed these calculations can become. It allowed the value of imported battery cells used in qualifying production or assembly in free zones to count toward domestic production costs, capped at 15% of the vehicle's price. The new direction would place more value on making important components in Thailand.

Parts suppliers and workers are central to that shift. A stronger reward for domestic electronics and other valuable components would give manufacturers a financial reason to buy more from Thai suppliers and expand production beyond final assembly.

The earlier incentives opened the market

Thailand's government began its EV push by making electric vehicles cheaper to import and buy while encouraging manufacturers to establish local operations. An official government tax policy explanation, published by the Public Relations Department's Mukdahan office, describes Cabinet measures based on EV Board decisions in 2021 and 2022.

The document records a reduction in BEV excise tax from 8% to 2% to encourage both use and production. It also describes proposed customs duty reductions for fully imported battery electric cars: the general rate would fall from 80% to 40% for vehicles with a recommended retail price up to 2 million baht, and to 60% for vehicles priced above 2 million and up to 7 million baht. Separate treatment applied under free trade agreements.

The same framework considered duty exemptions for components including batteries, traction motors, battery management systems and power electronics. Finance Minister Arkhom Termpittayapaisith, who held the role at the time, presented the measures as part of an effort to make Thailand an ASEAN production centre for EVs and their parts.

EV 3.0 and EV 3.5 carried that strategy forward by linking initial imports to later domestic production. Under EV 3.5, participating manufacturers must produce two vehicles in Thailand for each vehicle imported under the programme in 2026, rising to three in 2027. The requirement therefore increases by half between those years.

The latest tax proposal would add another incentive to those production obligations. Companies serving the market mainly through finished imports would face a much higher tax bill, while manufacturers building a deeper Thai supply network would receive more favourable treatment.

The dates that shape the transition

Thailand's proposed import increase sits alongside an older schedule of changes affecting combustion vehicles, hybrids and other vehicle categories. The official government explanation set out phased excise changes in 2026, 2028 and 2030, linked to emissions and vehicle characteristics.

The main policy milestones are:

• 2021 and 2022: EV Board decisions formed the basis for Cabinet measures supporting EV imports, purchases and production.
• 2026: EV 3.5 requires two locally produced vehicles for each qualifying imported vehicle.
• September 10, 2026: The EV Board adopted the direction for restructuring vehicle excise taxation. The Cabinet later assigned the Excise Department to develop the details.
• September 2026: Finance officials targeted completion and Cabinet submission of the proposed rates.
• January 1, 2027: The proposed higher rate for fully imported EVs is expected to begin. EV 3.5's production requirement also rises to three domestic vehicles per qualifying import in 2027.
• 2028 and 2030: Further stages of the earlier vehicle excise schedule are due.

Manufacturers would need to plan for both sets of changes: the tax treatment of vehicles they sell and the production commitments attached to incentives they have already received.

A growing market, with imports still prominent

Board of Investment figures put battery electric vehicle registrations at 126,950 in January through July 2026, up 88% from the same period a year earlier. BEVs, conventional hybrids and plug-in hybrids together accounted for 55% of vehicle registrations during those seven months.

The Federation of Thai Industries' sales figures and the registration figures measure different stages of the market. Sales track vehicles sold, while registrations track vehicles entered into the registration system. Both show why officials are reassessing incentives as electric and hybrid vehicles take a larger share of demand.

The investment figures are substantial, too. As of August 31, 2026, BOI data listed 189 EV related projects with promoted investment of 151,372 million baht, or about 151.4 billion baht. Promoted investment covers projects supported through the investment promotion system, with spending and production developing over time.

Ekniti said nine EV manufacturers had established operations in Thailand, with several already exporting locally made vehicles. The earlier incentive programmes attracted eight major Chinese automakers to build factories for domestic sales and exports. Those figures describe different groups: the Chinese investors attracted by the programmes and the wider number of EV manufacturers operating in the country.

Some companies importing vehicles from China and Europe have begun discussions with the government about Thai manufacturing. GlobalData forecasts strong growth in Thai EV production, with the largest increases expected in 2027 and 2029. The proposed tax would strengthen the financial incentive to join that expansion.

Emissions would matter alongside local investment

The wider reform would increasingly base vehicle excise rates on carbon dioxide emissions and value created in Thailand rather than favouring a particular propulsion technology. Battery electric vehicles, vehicles with engines that extend electric driving range, and hybrids would all fall within the broader policy.

A battery electric vehicle runs on electricity stored in its battery. A range extended electric vehicle also carries an engine to generate electricity and extend its range. A hybrid combines an engine and electric power, while a plug-in hybrid can recharge its battery from an external electricity supply.

The official earlier framework already linked tax treatment to emissions and technical requirements. For plug-in hybrids, it considered an electric driving range of at least 80 kilometres per charge and fuel tank size. It also included requirements for driver assistance safety systems.

The new proposal adds a stronger domestic production test to that environmental direction. A manufacturer's tax position would depend increasingly on both the vehicle's emissions and the investment, parts production and employment it brings to Thailand.

Protecting factories while keeping cars affordable

Ekniti has said Thailand's free trade commitments limit its ability to change customs tariffs directly, leaving excise taxation as the government's main mechanism for supporting manufacturers based in the country.

The government wants to preserve the extensive automotive supply network developed through decades of Japanese investment while accommodating newer Chinese EV factories. A Finance Ministry source described the reform as a continuation of the industrial strategy, rather than a measure designed specifically to favour Japanese automakers.

Federation of Thai Industries spokesperson Surapong Paisitpatanapong has also called attention to the continuing importance of combustion vehicle and pickup production, suggesting support for hybrids and pickups compatible with B20 biodiesel. The policy debate therefore reaches beyond battery electric cars to factories and suppliers serving several vehicle technologies.

Buyers and manufacturers face different pressures. Higher taxes could make some imported models less affordable, while local factories would gain a stronger incentive to expand and source more parts domestically. The government's task is to convert a fast growing EV market into sustained production, exports and skilled jobs without losing the consumer demand that helped attract investment.
