Thailand EV 3.5 and import duties: what actually applies in October 2026

1. Status board: what is active, ended or only proposed

As of 16 October 2026. Policy in Thailand changes by Cabinet or EV Board decision, often announced before it is gazetted.

2. Subsidy amounts by year and battery size

The subsidy is a per-vehicle payment to the manufacturer or importer. It applies only to passenger cars with a recommended retail price of up to ฿2 million, and only for makers that signed the scheme. Cars priced from ฿2 million to ฿7 million with a battery of 50 kWh or more get the excise cut, but the official Excise release lists no cash subsidy for that band.

Sources (official): BOI, 19 Dec 2023 and Excise Department, 19 Jan 2024 for EV 3.5; Thai Government, 25 Sep 2026 for EV 3.0. The step-downs are a published schedule; we found no announced change to the 2026–2027 amounts. At exactly 50 kWh the BOI table puts the car in the upper tier, but the Excise release's Thai wording overlaps, so the maker's certification decides.

3. How the subsidy reaches you

You do not apply for it. The Thai Government stated on 25 September 2026 that EV 3.0 subsidies are paid to manufacturers or importers and deducted from the retail price, and that buyers do not have to return any discount if a maker later defaults. EV 3.5 uses the same maker-claims-from-Excise design and Thai dealers advertise prices with it included. We did not find an equivalent explicit statement written for EV 3.5 buyers, so treat that part as strongly implied rather than confirmed.

Payment to the maker is conditional. Under the EV 3.0 rules the Excise Department can withhold subsidy payments until a maker has built enough compensating vehicles (BOI, 30 Jul 2025), and similar conditions were reported for EV 3.5 in November 2025 (press, not re-checked). We could not verify whether every October 2026 sale is currently being reimbursed. In practice, the risk sits with the maker, not with you, but it can show up as thinner dealer discounts or a brand reshuffling its prices.

4. Import duty, excise and VAT

Import duty

EV 3.5 offered an import-duty cut of up to 40% on fully built cars priced up to ฿2 million, for cars imported in 2024 and 2025 only (Excise, 19 Jan 2024). It is not available for cars imported under the scheme in 2026. Separately, many Chinese-built cars already entered at low or zero duty under the ASEAN–China free-trade agreement. That treatment depends on proof of origin, not on the badge, and it is independent of EV 3.5 (reported; not re-checked by us). So the end of the EV 3.5 duty cut does not by itself mean full tariffs on every Chinese-built car.

Excise tax

Petrol and hybrid excise depends on CO₂ and engine size; we did not verify those band tables, so none are shown. Excise is charged on a base set by the manufacturer or importer, not on the sticker price. For scale only: on a ฿1,000,000 excise base, 2% is ฿20,000, 8% is ฿80,000 and 10% is ฿100,000.

VAT

Standard VAT is 7%, charged on the price including excise. We found no general EV VAT exemption. An extension of the 7% rate to 30 September 2027 was reported from a Revenue Department release of 27 July 2026, which we did not re-check.

5. The local-production offset: why makers can be penalised

Makers that brought in subsidised cars as fully built imports must build cars in Thailand to offset them. The ratio is imported cars to locally produced cars.

The official releases do not spell out which import batch each EV 3.5 ratio applies to. Each car built for export counts as 1.5 cars toward the offset (EV Board, via BOI, 30 Jul 2025).

Penalties. For EV 3.0 shortfalls the government said on 25 September 2026 that Excise can recover the subsidy for each unit not offset, plus 7.5% simple annual interest, can call on the maker's bank guarantee, and may add excise, surcharges or fines. Each case is investigated and ends in an administrative order that can be appealed. A shortfall is not proof that a maker has defaulted.

6. Brands: what we could and could not confirm

Being in the scheme, having a Thai factory and having discharged the offset are three different facts. Only the first is documented for some brands, and only by press for others.

7. What buyers actually pay: three October 2026 examples

Advertised prices below are the 1–31 October 2026 campaign prices from an authorised BYD dealer (Rêver Automotive, 2 Oct 2026) and Tesla's Thailand configurator (accessed 16 Oct 2026). Both BYD cars list batteries of 50 kWh or more, so we assume the ฿50,000 tier is already inside their prices. That assumption follows the scheme rules, not an invoice.

ESTIMATE rows are our arithmetic, not tax receipts. VAT assumes the advertised price is the VAT-inclusive invoice price. Excise assumes a base of (list price + ฿50,000) ÷ 1.07 taxed at 2%; the real declared base is not published. We left Tesla's excise and duty blank because its scheme status, excise declaration and origin documents are unverified. Imported components in Thai-built cars may carry their own duty. Registration, insurance and dealer fees are excluded.

Campaign prices change monthly and can end early. For the Sealion 7 and Deepal S07, which are imported, see our comparison and the BYD three-way comparison; the new excise proposal would matter most for imported models, but no rate has been set.

8. Other costs of ownership

• Annual vehicle tax. DLT's published example is ฿1,600 a year for an 1,800 kg electric car. A temporary 80% reduction (฿320 in that example) covered new EVs registered through 10 Nov 2025 (DLT, 26 Apr 2024). A replacement 80% cut was only proposed in April 2026, so do not count on it.
• Registration fees. We did not verify a consolidated fee total. Ask the dealer for an itemised statement that separates statutory fees, tax, compulsory insurance and dealer handling.
• Insurance. Read the policy wording for battery cover, depreciation, flood damage and charging equipment. Cover terms differ between insurers.
• Home charger. We found no universal MEA or PEA household installation grant. BOI's charging incentives are for businesses. Maker promotions are separate and may exclude the lowest-payment option. See the Thailand home charger guide for costs and meter steps.
• Electricity. The PEA base time-of-use rates are ฿5.7982/kWh peak and ฿2.6369/kWh off-peak, before the Ft charge and VAT. We could not confirm MEA's current residential rate; the charger guide shows how we handle that.

9. If you are a foreigner

Ownership. Foreigners can register vehicles in their own name. DLT's registration rules provide for foreign applicants with identity documents and proof of residence or a work permit (DLT regulation, Royal Gazette, 4 Oct 2019). Registering does not require marriage to a Thai citizen.

Documents. We could not establish a universal list. A Thai driving licence is a separate matter from registration. We could not confirm that a yellow house book is always required, or that a TM30 alone is always accepted as address proof. Get the accepted address-document list from the registering DLT office before you pay.

Financing. Possible but lender-specific. One lender publishes a foreign-applicant checklist that includes a valid work permit, salary evidence and recent bank statements (Toyota Leasing, accessed 16 Oct 2026). A long-stay visa alone may not satisfy a lender.

The subsidy. Because it is deducted from the retail price, you see it as a lower price. We found no official clause that excludes foreigners, and no clause that confirms identical treatment, so we cannot call foreign-buyer eligibility confirmed. Ask the dealer to put the final price in writing.

10. Timeline and outlook

The proposed structure has tiers for importers without a Thai factory (highest excise), makers with a Thai plant that import a few models for market testing, and locally assembled cars with lower brackets by local content. The BOI and Cabinet reports give no percentages. A 31–39% figure reported on 9 September 2026 came from a private-sector proposal, and we do not treat it as a government rate. Officials have described the next framework as relying on excise rather than budget subsidies (Nation, 10 Sep 2026), but no successor purchase-subsidy scheme was confirmed.

What this means if you are deciding now: the published subsidy does not step down again before the end of 2027, but imported models face a policy that is moving. Nobody can yet say whether prices will change, by how much, or when.
