If you’re looking at setting up a BOI company in Thailand, you’re already thinking about one of the most effective structures available to foreign business owners. A BOI-promoted company gives you 100% foreign ownership, significant tax benefits, and a direct line to government support, things you simply can’t get through a standard company registration.
This guide walks you through what a BOI company in Thailand actually is, whether your business qualifies, what the benefits look like in practice, and how the application works in 2026.
What Is a BOI Company in Thailand?
The short answer to what a BOI company in Thailand is The Board of Investment (BOI) is a Thai government agency whose job is to attract high-value investment into Thailand. A BOI company in Thailand is still registered as a standard Thai Private Limited Company under the DBD. What makes it different is the Investment Promotion Certificate issued by the BOI, which unlocks your approved incentives and grants your company a Foreign Business Certificate, allowing you to hold up to 100% ownership depending on your sector.
Important: BOI grants a Foreign Business Certificate that bypasses the restrictions in FBA Lists 2 and 3. However, FBA List 1 businesses, such as land trading, farming, and domestic broadcasting, remain off-limits regardless of BOI status. |
What Are the Benefits of a BOI Company in Thailand?
2026–2027 Update: The refreshed incentive framework includes a new productivity enhancement measure, a 5-year CIT exemption capped at 100% of your investment in automation, digital adoption, or energy efficiency upgrades. This improves on the previous 3-year, 50%-capped measure and applies even to existing companies without prior BOI status. |
Non-tax benefits of a BOI company in Thailand
Beyond the tax, every BOI-promoted company receives the following regardless of which incentive tier applies:
- 100% foreign ownership, no Thai partner, no 49/51 structure, no nominee arrangements needed
- Unlimited hire of foreign skilled workers, the standard 4:1 Thai-to-foreign ratio doesn’t apply
- Simplified visa and work permit processing through the BOI One Stop Service Centre
- Import duty exemption on machinery and raw materials used in your promoted activity
- Permission to own land in Thailand for promoted business purposes
- Permission to remit profits and funds abroad in foreign currency
The work permit benefit alone is significant. Instead of navigating Thailand’s standard immigration system, BOI companies process visas and work permits through a single dedicated centre, faster, more straightforward, and with fewer documentation hurdles.
Which Business Activities Qualify for a BOI Company in Thailand?
The four main categories eligible for a BOI company in Thailand:
BOI promotion isn’t available to every type of business. The BOI publishes an official list of promoted activities, and your project needs to fall within one of the four main eligible categories:
- Agriculture, Food, Biotechnology & Medical: food processing, bio-products, medical devices, wellness services, smart farming
- Machinery, Automotive, Electrical & Electronics: EVs, EV parts and infrastructure, automation systems, advanced robotics
- Metals, Materials, Chemicals & Public Utilities: clean energy, renewables, advanced materials, petrochemicals
- Digital, Creative Industries & High-Value Services: software, data centres, AI, cloud services, generative AI, quantum computing, R&D, logistics, and STEM training
2026 Addition: Generative AI, quantum computing, and advanced robotics were added as new subcategories in the 2026 refresh. Digital and software businesses, including SaaS, data hosting, and cloud services, sit squarely within Category 4 and regularly receive BOI promotion. BOI is not just for manufacturers. |
2026 Priority Measures for a BOI company in Thailand
Beyond the standard categories, the BOI is currently fast-tracking certain types of applications through 2026–2027:
- Comprehensive Relocation: for companies moving manufacturing and headquarters (IBC) to Thailand simultaneously
- Industry 4.0 Upgrades: for existing businesses, even those without prior BOI status, adopting automation or green energy
- FastPass: accelerated approval for high-priority sectors including data centres, clean energy, and advanced technology
Eligibility Criteria for a BOI Company in Thailand
What the BOI looks for when reviewing a BOI company in Thailand application
Meeting the activity eligibility is only the first step. Your project also needs to satisfy the following criteria before the BOI will approve it:
- Value-added of at least 20% of revenues, 10% for agriculture, electronics, and certain manufacturing
- Modern production or service processes must be used and approved by the board
- New machinery and used machinery have strict criteria and limited exceptions
- Minimum capital investment of THB 1 million per project, excluding land and working capital
- Debt-to-equity ratio of no more than 3:1 for new projects
- Projects with THB 10 million or more in investment capital must obtain ISO 9000 or ISO 14000 certification
- Projects with an investment of over THB 2 billion must submit a full feasibility study before approval
- From March 2026: projects must demonstrate carbon reduction targets and renewable energy usage in line with Thailand’s BCG strategy
For knowledge-based and digital businesses, the BOI may assess eligibility based on minimum annual salary expenditure rather than capital alone, making BOI accessible for lean tech and service businesses that don’t require significant physical infrastructure.

How to Register a BOI Company in Thailand in 2026
Step-by-step process for setting up a BOI company in Thailand:
The full process from application to operational company typically takes 2–3 months for straightforward cases. Here’s how it works:
Confirm your activity is on the promoted list:
Check the BOI’s official investment guide at boi.go.th and identify your specific activity code and incentive tier. This determines your benefits, criteria, and certificate conditions.
Prepare your project proposal: The BOI requires a detailed investment proposal covering your activity, processes, machinery, employment projections, and financial plan. Projects over THB 200 million need additional environmental documentation.
- Submit via the OSOS online platform: Applications go through the BOI’s One Stop Operating System (OSOS). The entire submission, including identity verification and document upload, can be completed online. You don’t need to be in Thailand to apply
BOI review, interview, and approval:
Projects under THB 200 million are reviewed monthly. Simple, well-prepared applications typically receive approval in 5-6 months. Under the 2026 FastPass initiative, priority sector applications are being accelerated.
- Receive your Investment Promotion Certificate: Your certificate specifies exactly which incentives apply, the conditions you must comply with, and your project timeline obligations. This is the governing document for your promoted company
Is a BOI Company in Thailand Right for You?
If your sector is on the promoted list and your investment meets the minimum criteria, a BOI company in Thailand is almost always the best structure available. The ownership flexibility alone removes the need for Thai partners, nominee arrangements, or the documentation burden that comes with the new DBD shareholder rules, and the tax benefits on top of that make it genuinely compelling.
If you’re not sure whether your business qualifies, the most useful first step is a straightforward eligibility check. Many businesses that assume they don’t qualify, particularly in digital services, software, and healthcare, turn out to be eligible once the activity list is properly reviewed.
