Thailand BOI Announcement 8/2565 — 5-Year Investment Promotion Strategy 2023-2027

Mechanism

Announcement 8/2565 is Thailand's master investment-promotion policy document under the Investment Promotion Act B.E. 2520 (1977). It replaces the prior 2015-2021 BOI strategy and supplies the legal basis for activity-specific announcements that grant corporate-income-tax holidays, import-duty exemptions, foreign-land-ownership rights, and non-tax facilitation (visas, work permits) to promoted projects.

Activity-Group classification is the operative mechanism:

• Group A1+: 10-13 years CIT exemption with no ceiling on

tax-exempt revenue; targets technology-frontier activities such as wafer fabrication, advanced packaging, biotechnology, and certain EV-supply-chain components.

• Group A1, A2, A3, A4: 3-8 years CIT exemption with revenue cap

set to investment value.

• Group B1, B2: Non-tax incentives only (machinery duty

exemption, land-ownership, foreign-expert facilitation).

Merit-based additional incentives can extend CIT exemption by 1-3 years for investments in R&D, training, local linkages, or location in Special Economic Zones (SEZs) and the Eastern Economic Corridor (EEC).

Downstream implications

• Sets the legal and incentive perimeter for every subsequent Thai

BOI sectoral instrument 2023-2027 (EV 3.5, HEV excise, semiconductor strategy 2026-2050, EEC promotions, smart-electronics PLI).

• Frames Thailand's competitive positioning against Vietnam, Malaysia

and Indonesia in the regional FDI-for-supply-chain-diversification contest accelerated by the post-2022 US export-control regime.

• Reinforces the BCG-economy direction (Bio-Circular-Green) as the

cross-cutting filter for project approvals — relevant to upstream agro-processing, bio-refining, and circular-economy materials.

Open questions

• Quantitative scale of Group A1+ CIT exemption granted to date

(BOI annual statistics 2023-2025) — not yet aggregated in register.

• Whether the strategy will be formally extended past 2027 or

replaced by a successor announcement under the next administration.
