How much will Thailand tax imported electric cars? From 1 January 2027, fully imported EVs will pay an excise tax of 35 percent, up from 10 percent today, while qualifying locally manufactured EVs currently pay just 2 percent, CNA reported. The government says it wants to reward companies that build cars in Thailand, protect decades of automotive investment and draw more of the EV supply chain into the country.
The change lands in the middle of an EV boom. Sales of battery electric passenger cars nearly doubled in the first nine months of 2026, and Chinese brands dominate. For buyers, it means a likely rush before the deadline and higher prices on some imported models next year. For carmakers, it is a clear message: build here, or pay much more.
What changes on 1 January
An excise tax is a tax charged on the sale of a particular product, and for cars it is a big part of the final price. Raising it from 10 to 35 percent on fully imported EVs widens the gap with locally built cars, which qualify for a 2 percent rate. Experts noted that the previous eight percentage point gap had done little to discourage imports.
The government is also proposing a three tier system that would give preferential rates to manufacturers using Thai made components. Those meeting a possible 40 percent local content threshold would pay 10 percent, while those that do not would face higher rates. The rules would also apply to EVs made in neighbouring countries, which could complicate efforts to build integrated supply chains across ASEAN.
Thailand's broader goal is for zero emission vehicles to make up at least 30 percent of domestic vehicle production by 2030. Under earlier incentive schemes, carmakers could import EVs at preferential rates if they committed to build cars locally later. The new tax is meant to shift that balance decisively toward production.
Who wins and who loses
Chinese manufacturers already producing in Thailand are best placed. BYD runs a factory in Rayong with annual capacity of 150,000 vehicles, MG, the British brand now owned by China's SAIC, builds cars in Chonburi with capacity of up to 100,000, and GAC Aion recently opened a battery pack assembly plant. Leapmotor, XPeng and Dongfeng are examining local assembly, according to Thai media.
Brands that only import face a steep jump. "Take Tesla for example. Tesla doesn't have a manufacturing base in Thailand, so they have to go for 35 percent," said Krisda Utamote, honorary adviser at the Electric Vehicle Association of Thailand, unless it decides to build a plant. Thammasat University professor Pavida Pananond warned that some brands could drop imported models or exit the market rather than build locally.
Japanese carmakers, who built Thailand's automotive industry over decades, could gain breathing room. Japan's ambassador warned last week that cheap imports threatened a manufacturing and export base employing about 800,000 people. The Thai government denied the tax was designed to appease Japanese manufacturers, saying the goal was domestic production and local supply chains.
Thailand let Chinese EVs in to start the transition. Now it wants Chinese factories to finish it.
What it means for buyers
For drivers, affordability is the main concern. Many popular EVs in Thailand cost between 500,000 and 900,000 baht, helped by subsidies. Ride hailing driver Pichai Phungmai told CNA that a price rise of 100,000 baht or more would put an EV out of reach. Experts expect several effects:
- a rush to buy imported models before 1 January 2027
- carmakers importing and clearing stock through customs before the deadline
- prices that may not jump immediately in January, as old stock is sold
- fewer imported models and higher prices for some brands later in 2027
- more choice and keener pricing among locally built EVs
Krisda expects manufacturers to bring in vehicles before the deadline so they can sell existing inventory under the old tax next year, which could soften the immediate impact. Over time, though, buyers who want a model that is not built in Thailand should expect to pay more.
Pavida called the tax "a corrective measure" and said "the direction is right, but it comes late. Chinese brands already dominate Thailand's EV market." Chinese made EVs accounted for about three quarters of all electric car sales in 2025, according to the International Energy Agency.
How Thailand's neighbours are handling Chinese EVs
Thailand is not the only target for Chinese carmakers. Chinese manufacturers are expanding across Southeast Asia, including in Malaysia and Indonesia, while Vietnam has developed a substantial domestic EV market led by VinFast, the carmaker backed by Vingroup, whose finances we examined in our report on Vingroup's first 1 billion dollar quarterly profit.
That competition matters for Thailand's ambition to remain the region's car manufacturing hub. If Chinese brands decide that Indonesia's large market or Malaysia's incentives offer better terms, they may choose to build there and export across ASEAN instead. Thailand's higher import tax would then apply to cars made by its neighbours, which some experts say could undermine the goal of an integrated regional supply chain.
Krisda of the EV association accepted that trade off. "It is what it is. The government decided to put up this barrier," he said. "Otherwise they have no other measure to protect themselves."
The bigger picture for Thai industry
Thailand's carmaking industry has long served Japanese companies and the thousands of parts needed for petrol and diesel engines. EVs need fewer and different parts, and the highest value components, batteries, motors, power electronics and software, are hard to localise. Chinese carmakers tend to keep those within their own groups or trusted Chinese suppliers.
Thai suppliers welcome measures that give them a fair chance in the EV supply chain, but face Chinese competitors with huge home markets and lower costs. Pavida said Thailand can adapt existing capabilities in bodies, seats, wiring and glass, but needs time and targeted incentives to move into higher value layers.
The tax also fits a regional pattern. As China's exports surge, including cars, governments across Southeast Asia are weighing how to welcome investment without being swamped by imports, a dynamic we explore in our report on China's trillion dollar trade surplus.
What is Thailand's new EV tax?
From 1 January 2027, the excise tax on fully imported electric vehicles rises from 10 percent to 35 percent.
What tax do locally made EVs pay?
Qualifying locally manufactured EVs currently pay 2 percent excise.
Why is Thailand raising the EV import tax?
To protect domestic manufacturing, reward companies that build locally and draw more of the EV supply chain into Thailand.
What is the 40 percent local content rule?
A proposed tier under which manufacturers using at least 40 percent Thai made components would pay 10 percent excise.
Will EV prices rise in Thailand in 2027?
Some imported models are likely to cost more, though stock imported before the deadline may soften the immediate impact.
Should I buy an EV in Thailand before January 2027?
Buyers of imported models may benefit from buying before the tax rises, while locally built models are less affected.
Does Tesla build cars in Thailand?
No. Without a Thai plant, its imported cars would face the 35 percent rate.
Where does BYD build cars in Thailand?
In Rayong, at a factory with annual capacity of 150,000 vehicles.
Where does MG build cars in Thailand?
In Chonburi, with capacity of up to 100,000 cars a year.
How many EVs were sold in Thailand in 2026?
More than 161,000 battery electric passenger cars in the first nine months, nearly double a year earlier.
How dominant are Chinese EVs in Thailand?
Chinese made EVs were about three quarters of electric car sales in 2025, and China supplied 96 percent of EV imports by value in early 2026.
Does the tax apply to EVs made in ASEAN?
Yes. It would apply to EVs manufactured in neighbouring countries, experts said.
What is Thailand's EV production target?
At least 30 percent of domestic vehicle production to be zero emission by 2030.
Will Chinese brands leave Thailand?
Some import only brands could drop models or exit, while others such as Leapmotor, XPeng and Dongfeng are studying local assembly.
Who benefits from the new EV tax?
Carmakers with Thai factories and potentially Thai parts suppliers, while import only brands and some buyers lose out.
What is an excise tax?
An indirect tax charged on the sale of a particular product, which for cars is a significant part of the final price.
Thailand is changing the terms of its EV boom: cheap imports opened the market, and local production is now the price of staying in it. Buyers should expect a busy December and a more expensive menu of imported models next year, while carmakers decide whether Thailand is worth a factory.
