Thailand's Board of Investment issued Notification No. 9/2568 on 14 November 2025, amending the Activity List Eligible for Investment Promotion by splitting the prior single data-center category into two tiers based on power-usage efficiency: high-efficiency data centers (PUE ≤ 1.3) qualify for an 8-year corporate income tax (CIT) exemption, while other data centers receive a 5-year CIT exemption. A precursor restructure (Notification No. 5/2568, 5 June 2025) first introduced the two-tier category split; Notification 9/2568 added location-differentiated terms based on the Eastern Economic Corridor (EEC). New benefit conditions require applicants to submit a Thailand-benefit plan — training programmes, academic/R&D partnerships, local supply-chain support, or knowledge transfer to Thai nationals — that must be implemented before CIT exemption benefits can be exercised.

On 19 December 2023, the Thai Cabinet endorsed the second phase of the national electric-vehicle support programme ("EV 3.5") covering 2024-2027, following its approval by the National Electric Vehicle Policy Committee. The Excise Department published the implementing Notification on 28 December 2023; the regime entered into force on 1 January 2024. EV 3.5 combines (i) per-vehicle purchase subsidies of THB 50,000-100,000 for battery-electric passenger cars and pick-ups, (ii) a reduction in excise duty on BEV passenger cars priced ≤ THB 7 million from 8% to 2%, and (iii) up to 40% import-duty relief on Completely Built-Up (CBU) BEV passenger cars priced ≤ THB 2 million during 2024-2025. Participating OEMs must offset CBU imports with domestic Thai production at a 1:2 ratio by end-2026 and 1:3 by end-2027, or face clawback of the granted incentives. The package is the operational successor to EV 3.0 (2022-2023) and was designed to lock in the wave of Chinese-OEM gigafactory and assembly investment that EV 3.0 attracted (BYD Rayong, MG/SAIC, GAC AION, Great Wall Motor, NETA, Changan, Chery). By the August 2025 EV-Board meeting Thailand had logged > THB 137 billion in approved EV-supply-chain investment under the combined EV 3.0 + EV 3.5 envelope. EV 3.5 is the central instrument in Thailand's "EV Hub of ASEAN" industrial strategy and the principal regional competitor to Indonesia's nickel-anchored EV-cluster bid and Vietnam's Decree 182 investment-support fund.

On 8 December 2022 the Thai Board of Investment issued Announcement No. 8/2565 "Policies and Criteria for Investment Promotion", setting Thailand's five-year (2023-2027) horizontal investment-promotion strategy. The Announcement entered into force from 8:30 a.m. on 3 January 2023 and applies to all investment-promotion applications filed with the BOI from that date. The strategy reorients Thailand's investment regime around three core concepts — (i) innovation, technology and creativity, (ii) competitiveness and rapid adaptability, and (iii) inclusiveness, including environmental and social sustainability — and is operationalised through seven pillars: industrial transition to BCG (Bio-Circular-Green) / smart industries, regional-hub positioning (EV, electronics, food, medical, aviation, automation), supply-chain strengthening, technology upgrading, SME competitiveness, sustainable development, and BCG-economy alignment. Incentives are structured into Group A (corporate-income-tax exemption for 3-13 years, with Group A1+ activities — frontier-technology semiconductors, advanced biotech, certain EV components — receiving up to 10-13 years CIT exemption with no cap) and Group B (non-tax incentives only). Fundamental eligibility criteria carried over from prior regimes: minimum THB 1 million investment, new-machinery requirement, 20% annual revenue-growth projection, and a 3:1 debt-to-equity threshold. The 8 December 2022 release was accompanied by 16 additional implementing announcements (Announcements 9/2565 to 24/2565) covering specific activity lists and merit-based incentives. This is the umbrella framework under which Thailand's subsequent sector-specific BOI instruments operate — the EV 3.5 package (2023-12-19, effective 2024-01-01), the EV Board HEV manufacturing excise incentives (2024-07-26), and the National Semiconductor and Advanced Electronics Industry Strategy (2026-01-07) all sit inside this 2023-2027 investment-promotion regime.
