The AmendedEV3 and EV3.5 incentive schemes, approved on 25 November 2025 and implemented by the BOI, reflect Thailand’s effort to balance electric vehicle market growth with fiscal discipline and its long-term ambition to become a regional EV manufacturing and export hub. The amendments introduce greater flexibility in registration timelines while tightening the conditionality of incentive benefits.
Key changes include extended registration deadlines for domestically produced EVs, conditional subsidy payments linked to production and localization milestones, and mechanisms allowing production compensation across EV3 and EV3.5 projects. Temporary relief for imported battery cells is extended to mid-2026, subject to reduced localization thresholds and mandatory localization plans. The Amendments also refine export treatment and provide an exit option for participants who have not received subsidies, subject to repayment of excise tax benefits.
From a legal perspective, the amended schemes signal a shift toward stricter enforcement and monitoring of incentive conditions. Incentives are no longer automatic but contingent on measurable compliance, thereby mitigating oversupply risks while reinforcing Thailand’s broader EV industrial and export policy.
