Thailand Plans 300,000 More EVs With Taxi Trade-Ins and Vehicle Tax Cuts

300,000 Vehicles Targeted as Thailand Widens Its Electric Transport Push

Thailand is preparing measures to bring 300,000 additional electric vehicles onto its roads, including a trade-in scheme targeting about 27,000 diesel taxis and annual vehicle tax cuts of up to 80 percent. Deputy Transport Minister Siripong Angkasakulkiat outlined the proposal after discussions with the Department of Land Transport, as the government seeks to extend its electric vehicle incentives to more commercial operators.

As of April 26, 2026, the package still requires cabinet approval. The measures could take effect as early as June through a royal decree. Electric and hybrid vehicle owners could receive substantial reductions in their annual vehicle taxes, or a complete waiver during an initial transition period.

The proposal builds on Thailand's EV3.0 and EV3.5 programmes, which use subsidies and tax relief to encourage purchases and local manufacturing. Its new focus is on vehicles that earlier programmes addressed less comprehensively: taxis, other commercial fleets and vehicles entering the used car market.

The financial commitment is already substantial. Tax incentives have supported the registration of more than 134,000 vehicles at a cost exceeding 19 billion baht. The proposed expansion connects that spending to a broader industrial goal: keeping Thailand competitive as automotive production shifts from engines burning petrol or diesel to electric motors and batteries.

Thailand is Southeast Asia's largest automotive producer, ranks among the world's top 10 automotive manufacturing hubs and is the region's second largest economy. Its vehicle industry supports manufacturing employment and export earnings. The planned changes therefore affect drivers, transport businesses, factories and the suppliers that make their parts.

How the Trade-In Scheme and Tax Cuts Would Work

The Transport Ministry is proposing two linked measures. One would extend the existing car trade-in policy beyond private vehicles to public transport operators, particularly taxis. The other would lower annual vehicle taxes for electric and hybrid models, with the Department of Land Transport working alongside the Ministry of Finance.

The trade-in proposal aims to replace approximately 27,000 diesel taxis with electric or hybrid alternatives. A trade-in allows an owner to put an existing vehicle toward the purchase of a replacement. For commercial drivers, the government is seeking to reduce both the expense of changing vehicles and the fuel costs associated with daily work.

Electric and hybrid models use different systems. A battery electric vehicle runs on electricity stored in its battery. A hybrid combines an electric motor with an engine that burns fuel. Both are included in the proposed annual tax relief, while the existing EV3.5 purchasing incentives focus on battery electric vehicles.

Annual vehicle tax is a recurring ownership expense, separate from the purchase price. Cutting it by as much as 80 percent, or temporarily removing it, would reduce the cost of keeping a qualifying vehicle on the road. The proposal therefore addresses ownership costs as well as the initial expense of buying a replacement.

Taxi Fuel Assistance Comes With a Mileage Requirement

Petrol taxis are also a focus of the government's current assistance measures. Under the diesel fuel aid scheme, the payment described for petrol taxi operators is a flat 5,040 baht per vehicle. Eligibility requires at least 2,500 kilometres of service during a support period lasting 42 days.

The Department of Land Transport uses a dedicated application to track compliance. The mileage requirement directs assistance toward vehicles actively providing transport services, rather than vehicles sitting unused. It connects public spending to actual commercial activity.

More than 55,000 transport operators and 206,000 vehicles have registered for diesel fuel aid. Those figures show the scale of participation in transport assistance, alongside the narrower proposal to replace about 27,000 diesel taxis.

The government has also restricted public transport driving licences to Thai nationals. The measure reinforces protections for domestic workers, while potentially narrowing the pool of people eligible to drive commercial electric vehicles as fleets expand.

What EV3.0 and EV3.5 Already Provide

Thailand launched EV3.0 in 2022 and approved EV3.5 for 2024 through 2027. EV3.5 took effect on January 1, 2024, combining purchasing subsidies, lower excise taxes and adjustments to import duties. Excise tax is a tax applied to particular goods, while import duty is charged when goods enter the country.

EV3.5 subsidies range from 25,000 to 100,000 baht per vehicle, depending on battery capacity and the year of purchase. Support within the programme also includes amounts of 50,000 to 100,000 baht through 2027. The amount available to a buyer therefore depends on the vehicle and the applicable purchasing period.

The programme reduces excise tax from 8 percent to 2 percent for electric passenger cars priced below 7 million baht. It also allows import duty reductions of up to 40 percent for completely built-up vehicles imported during 2024 and 2025. A completely built-up vehicle arrives as a finished car, rather than as parts for assembly in Thailand.

Manufacturers receiving these benefits face local assembly requirements. The stated terms call for one vehicle produced locally for every two imported by 2026, or one for every three by 2027. The purchasing incentives are therefore linked to manufacturing obligations, connecting consumer demand with domestic production.

By January 2024, 14 manufacturers had registered 78,554 electric cars under EV3. That provides an earlier measure of industry participation, while the figure of more than 134,000 registrations supported by tax incentives illustrates the wider scale of the government's spending.

A Policy Timeline From Subsidies to Production Targets

Thailand's electric vehicle strategy stretches across several years. The proposed taxi and tax measures sit alongside earlier consumer incentives, commercial vehicle tax support and deadlines for battery manufacturing applications.

• 2022: Thailand launches EV3.0 to support electric vehicle adoption.
• January 1, 2024: EV3.5 takes effect for the programme running through 2027.
• 2024 and 2025: Qualifying imports of completely built-up electric vehicles can receive import duty reductions of up to 40 percent.
• December 31, 2025: The stated period for special deductions on electric truck and bus purchases ends.
• 2026 and 2027: Local production requirements apply under the stated EV3.5 timetable.
• June 2026: The proposed vehicle tax and trade-in measures could begin, subject to cabinet approval and a royal decree.
• End of 2027: Battery cell manufacturers must submit proposals for the investment support described in the programme.
• 2030: The 30@30 policy targets electric vehicles accounting for 30 percent of domestic vehicle production.
• 2035: Thailand's longer term goal is 100 percent use of vehicles with zero emissions.

The 2030 manufacturing target and the 2035 vehicle use goal concern different parts of the transition. One addresses what factories produce; the other addresses the vehicles being used. The proposed 300,000 additional EVs would advance adoption while manufacturers adjust their production.

Electric Trucks and Buses Receive Separate Support

The National Electric Vehicle Policy Committee has also approved special tax deductions for companies replacing large truck and bus fleets with battery electric vehicles. The measures were specified as effective until December 31, 2025, giving this commercial programme a different timetable from the taxi proposal under consideration in April 2026.

Businesses purchasing electric trucks and buses manufactured in Thailand can deduct expenses equal to twice the actual vehicle price. Imported vehicles qualify for a deduction equal to 1.5 times their price. A tax deduction reduces the amount of income on which a company calculates tax; the deduction amount and the resulting tax saving are different figures.

The eligible vehicles include container trucks, vehicles transporting liquids, carriers of hazardous substances, special trucks and tow trucks. Electric buses qualify both with and without air conditioning. This scope takes the policy beyond private cars into freight movement and passenger transport.

Narit Therdsteerasukdi, secretary general of the Thailand Board of Investment and secretary of the National Electric Vehicle Policy Committee, explained the commercial vehicle measures at a press conference:

The measures approved today will complete the so-called EV3 and EV3.5 sets of measures taken earlier for the passenger car sector, by focusing this time on large commercial vehicles. We believe this will significantly increase the adoption of electric trucks and buses, reduce pollution from the transportation and manufacturing sectors, and support companies' moves to reach their net-zero targets.

The committee links those incentives to reducing emissions from heavy transport and supporting the 30@30 production goal. For businesses pursuing net zero, the objective is to reduce emissions and balance the emissions that remain.

Battery Manufacturing and Foreign Investment

Thailand is pursuing domestic battery cell manufacturing through the Competitiveness Enhancement Fund. Battery cells are the units that store electrical energy inside a vehicle's battery pack. Producing them locally would give the automotive industry a domestic source of a central EV component.

Manufacturers seeking investment promotion must demonstrate an energy density of at least 150 watt-hours per kilogram and a lifespan of no fewer than 1,000 cycles. Energy density describes how much energy a battery can store for its weight. A cycle refers to charging and using the battery's stored energy.

Companies must submit proposals by the end of 2027. The government views local battery production as a way to make Thailand's EV industry more durable and better able to withstand supply disruptions, alongside support for vehicle assembly.

Chinese automakers BYD and Great Wall Motor have collectively committed $1.44 billion to production facilities in Thailand. BYD's factory in Rayong aims for annual capacity of 150,000 vehicles from 2024. Changan Automobile has also announced plans for substantial production of battery electric vehicles and plug-in hybrids, which combine an engine with a battery that can be charged externally.

The local content requirement for products designated Made-in-Thailand is at least 40 percent of materials and components. That rule is intended to support domestic suppliers while helping manufacturers reduce dependence on Chinese supply chains and avoid potential tariff complications. Indonesia uses a comparable connection between domestic component levels and value added tax relief under its PPN DTP scheme.

Michael Ignatiadis, head of manufacturing strategy for Asia Pacific at JLL, notes that markets offering incentives are especially appealing during the early stages of investment. Manufacturers also have to consider the possibility that those incentives will later be reduced or removed. Rapidly introduced or excessive support can risk market saturation and labour shortages, increasing costs and putting pressure on local resources.

Charging Networks Must Keep Pace With More Vehicles

PTT and EGAT are leading charging infrastructure expansion as Thailand seeks to put more electric vehicles into service. PTT's Arun Plus subsidiary is targeting more than 7,000 charging points by 2030. EGAT's Elex project focuses on fast charging along highways to support travel over longer distances.

The Ministry of Energy and Ministry of Transport are coordinating charging station deployment with vehicle adoption. Drivers need access to electricity where they travel and work. Limited charging access can create range anxiety, the concern that a vehicle will run out of power before reaching a charger.

EGAT and Nissan are also testing systems that allow electric vehicles to return energy to the electricity grid during periods of peak demand. Known as vehicle-to-grid technology, this makes a vehicle battery a possible source of stored electricity as well as a source of power for driving.

Smart grid technologies and these trials aim to manage pressure on the electricity network while giving vehicle owners uses for their batteries beyond transport. Charging infrastructure, electricity supply and vehicle purchases are therefore connected parts of the same programme.

Regional Growth Shows the Importance of Incentive Stability

Thailand's push comes as ASEAN countries compete for investment in electric mobility and the industries supplying it. Thailand has achieved approximately 20 percent EV market penetration, while Singapore has exceeded 40 percent of new registrations, supported by subsidies of up to S$40,000 per vehicle.

The figures describe related measures of adoption: Thailand's market penetration and Singapore's share of new registrations. Singapore's figure places electric vehicles above two in every five new registrations, while Thailand's reported penetration is approximately one in five.

Malaysia has experienced annual EV growth of 100 percent, meaning its market doubled over the period described. Its tax holidays for imported EVs expired at the end of 2025, creating uncertainty about the incentives available after that deadline.

Thailand's own investment plans depend partly on the reliability of support over several years. A buyer deciding on a vehicle, or a manufacturer planning a factory, needs to account for purchasing benefits, production requirements and the dates when tax measures end.

Price, Scrapping and Electricity Concerns Remain

The proposed trade-in scheme has drawn concern about how much assistance would reach consumers. Critics warn that incentives channelled through carmakers could be partly absorbed by manufacturers rather than passed on to buyers, potentially distorting vehicle prices.

The proposed loan rate of 3.5 percent also faces comparison with EV financing already available at rates near zero in some market segments. Its value to a buyer would depend on the financing alternatives available for the vehicle being purchased.

The government has not settled the definition of an old vehicle eligible for trade-in. Transparent scrapping arrangements would be needed to ensure that vehicles intended for retirement leave active service. Without them, traded vehicles could return to use through secondary markets, weakening the pollution reduction sought by the scheme.

Environmental advocates have also raised concerns about electricity generation and the management of retired vehicles and batteries. More than half of Thailand's electricity comes from natural gas. An electric vehicle removes exhaust emissions at the vehicle itself, while generating the electricity used to charge it can still produce emissions.

The environmental outcome therefore depends partly on how electricity is produced, alongside the replacement of vehicles burning fuel. Comprehensive arrangements for handling vehicles and EV batteries at the end of their useful lives are another unresolved part of the transition.

Thailand's automotive industry, often called the Detroit of Asia, faces an economic shift as well as an environmental one. The proposed 300,000 additional EVs would widen demand beyond the private passenger car market. Its delivery depends on cabinet approval, the design of the trade-in rules, affordable financing, charging access and coordination with domestic manufacturing.
