Key Takeaways
- BOI revised its promotion conditions in 2024–2025, with notable changes to foreign employee quotas, land ownership privileges, and newly promoted sectors
- Digital services, semiconductors, EVs, green energy, and medical technology have seen expanded BOI coverage
- Companies with existing BOI certificates should urgently review compliance status; new applicants have fresh opportunities
Introduction
Thailand’s Board of Investment (BOI) promotion scheme remains one of the most powerful tools for Japanese companies entering Thailand — enabling full foreign ownership regardless of FBA restrictions, and providing significant tax benefits including corporate income tax exemptions. For a foundational overview of how BOI works, see our earlier article: BOI Investment Promotion: How to Operate Fully Foreign-Owned and Access Tax Benefits [Series Part 4].
This article focuses specifically on the changes BOI implemented and announced in 2024–2025, and their practical implications for Japanese companies.
1. Why Are BOI Rules Changing?
From “Thailand 4.0” to the BCG Economy
BOI promotion has evolved from a foreign investment attraction tool into an instrument of industrial policy. Thailand’s current government has adopted the BCG Economy (Bio-Circular-Green) as a national framework — and BOI’s promoted categories have been redesigned accordingly.
Alongside the manufacturing, automotive, and electronics sectors familiar to Japanese companies, BOI incentives have been significantly expanded in digital services, semiconductors, green energy, medical technology, and agricultural technology.
Alignment with FBA Reform
As discussed in our earlier article on FBA reform, BOI promotion and FBA liberalization are proceeding in parallel. Even if FBA restrictions are relaxed in certain sectors, BOI remains valuable for its tax privileges, foreign employment quotas, and land ownership entitlements. The two frameworks are complementary rather than alternatives.
2. Key Changes
① Changes to Foreign Employee Hiring Requirements
BOI-promoted companies can employ a higher number of foreign workers (work permit holders) than non-promoted companies. The traditional benchmark of “THB 2 million in paid-up capital per foreign worker” has been replaced with more flexible, sector-specific criteria.
In particular, requirements for foreign specialists in digital, IT, and advanced technology roles have been eased, supporting the establishment of startups and R&D centers.
Practical note: Companies with existing BOI certificates should verify that their current ratio of foreign employees to paid-up capital remains compliant under the new criteria, as discrepancies may be flagged during certificate renewal.
② Changes to Land Ownership Privilege Conditions
One of BOI’s most valuable benefits is permitting foreign-majority companies to own or hold long-term leases on land — an exception to Thailand’s general prohibition on foreign land ownership. Since 2024, the application of this privilege has been subject to stricter interpretation in practice.
Specifically, the use of BOI-privileged land for non-business purposes (such as staff accommodation or recreation facilities) has come under closer scrutiny. Ensuring that all land and buildings held under BOI privilege are used in ways consistent with the promoted business activities is increasingly important.
③ Newly Added and Expanded Promoted Sectors
The following sectors have seen significant additions or expansions to BOI promotion in 2024–2025:
| Sector | Key Incentives |
|---|---|
| Data centers & cloud services | 8-year CIT exemption, 100% foreign ownership |
| Semiconductors & advanced electronics | Up to 13-year CIT exemption, R&D deductions |
| EV-related (batteries, charging infrastructure) | Enhanced incentives across the supply chain |
| Green energy (solar, wind, hydrogen) | Expanded categories and longer exemption periods |
| Medical devices & biotechnology | Incentives for manufacturing and research facilities |
| Agricultural technology (AgriTech) | New categories for smart agriculture and food tech |
For Japanese manufacturers considering a shift toward EV supply chains or green manufacturing, BOI promotion now offers an increasingly compelling entry point.
④ Stricter Compliance Monitoring
Post-certificate compliance monitoring has intensified. BOI now conducts more rigorous checks on:
- Paid-up capital adequacy
- Actual commencement and operation of the promoted business
- Foreign employee-to-capital ratios
- Land and building usage consistent with the promoted activity
- Timely submission of annual reports
Companies that have not formally commenced their promoted business, or that have changed business scope without notifying BOI, face elevated risk of certificate revocation or penalties.
3. Practical Implications for Japanese Companies
① For Companies with Existing BOI Certificates
The most urgent priority is a comprehensive compliance review. Key areas to check include:
- Does your current foreign employee count remain within the newly applicable limits relative to paid-up capital?
- Is all land and property held under BOI privilege being used for the promoted business activity?
- Have any changes to your business scope (new products, services, or activities) been formally notified to BOI?
- Are annual reports being submitted on time?
BOI compliance audits occur periodically, and remediation after a problem is identified takes time and cost. Early detection and correction is strongly preferable.
② For Companies Planning to Apply for BOI
The expansion of promoted sectors creates new opportunities. Key considerations include:
- EV and green manufacturing companies transitioning their product lines may find BOI promotion significantly more accessible and valuable than before
- Digital and IT operations can leverage expanded data center and software development categories
- R&D centers can access special deductions for R&D expenditure in addition to standard BOI benefits
③ Combining FBA Reform and BOI Strategy
Even as FBA liberalization proceeds, BOI remains a superior option in many scenarios due to its tax, employment, and land advantages. The right strategy is not “FBA reform makes BOI unnecessary” but rather “how do we optimally combine both frameworks for our specific situation.”
4. Outlook
BOI revises its promotion conditions annually, and further changes are expected. The 2025–2026 period in particular — with FBA reform, OECD accession, and BCG policy all converging — may bring more fundamental restructuring of BOI promotion design.
Summary — Three Things to Do Now
① Conduct a full compliance review of your existing BOI certificate
Check your foreign employee ratios, land usage, business scope notifications, and annual report filing status. Address any gaps before they become issues.
② Assess whether your business qualifies under newly expanded BOI categories
If you are active in EV, green manufacturing, digital services, or medical technology, revisit your BOI eligibility — the landscape has changed.
③ Design an integrated FBA + BOI strategy
As the legal environment evolves, aligning your entry structure and operating model to take advantage of both frameworks will deliver a meaningful competitive advantage.
