At Voyage+, we help international entrepreneurs, investors and businesses navigate Thailand's investment environment. From identifying suitable BOI promotion categories to coordinating company formation, preparing investment applications and supporting foreign personnel, we provide tailored guidance at every stage.
Whether you are launching a technology company, establishing a manufacturing operation or expanding your international business into Thailand, the right investment structure can make a substantial difference.
Tax and non-tax incentives for selected industries and activities.
For eligible foreign investors, BOI promotion can provide several advantages over establishing a conventional Thai company.
Certain BOI-promoted activities permit full foreign shareholding, allowing eligible international investors to retain complete ownership of their Thai company without introducing Thai shareholders solely to meet ordinary foreign ownership restrictions.
Eligible investment projects may receive corporate income tax exemptions for periods of up to 13 years, depending on their approved promotion category and applicable investment conditions.
BOI-promoted businesses may benefit from specific procedures for recruiting eligible foreign executives, technical specialists and skilled professionals, subject to the necessary approvals.
Qualifying projects may receive import duty exemptions or reductions on eligible machinery and materials, as well as other investment privileges.
Certain promoted businesses may also obtain permission to own land required for their approved operations.
BOI privileges are not automatic. The benefits available depend on the approved project, applicable legislation and conditions imposed by the Board of Investment.
BOI promotion assesses a specific investment project, not a company registration.
The Thailand Board of Investment (BOI) is the government agency responsible for promoting investment in activities that support Thailand's economic development.
Its investment promotion programmes are designed to attract businesses that contribute to innovation, technology, industrial development, international competitiveness and other national priorities. Unlike ordinary company registration, BOI promotion involves an assessment of a specific investment project.
The BOI considers factors including:
If approved, the project receives an investment promotion decision setting out its applicable privileges and conditions.
BOI promotion is not the same as registering a company in Thailand. Company incorporation, investment promotion and any required business licences or foreign business authorisations are distinct legal and administrative procedures. At Voyage+, we help investors understand how these requirements interact before selecting their business structure.
Full foreign ownership through eligible BOI promotion
Under Thailand's Foreign Business Act, foreign-majority companies face restrictions when conducting certain business activities. Eligible BOI-promoted projects may benefit from more flexible arrangements, allowing 100% foreign shareholding for qualifying activities.
Foreign ownership: depends on the Foreign Business Act and other applicable regulations.
Incentives: standard corporate tax and customs treatment.
Regulatory obligations: additional licences or authorisations may be necessary for restricted activities.
Foreign ownership: an eligible project may benefit from full foreign ownership, subject to BOI approval.
Incentives: tax and non-tax privileges linked to the approved project.
Regulatory obligations: BOI conditions, reporting and project compliance apply in addition to other requirements.
Important: BOI promotion does not automatically remove every restriction on foreign ownership, nor does it authorise business activities outside the approved project. Which structure suits you depends on the project. Voyage+ assists with evaluating foreign ownership options and coordinating appropriate company structuring with authorised local professionals.
How much do you need to invest?
1,000,000 THB
General minimum qualifying project investment, excluding land and working capital. Activity-specific conditions may differ.
This threshold refers to qualifying project investment. It should not be confused with company registration costs, government application fees or the company's registered share capital.
Certain activities, particularly knowledge-based services, may be assessed using minimum annual expenditure on qualified personnel. Other industries may require substantially higher investment amounts, specialised equipment, technical capabilities or additional operational commitments.
The project must fall within an activity currently promoted by the BOI and satisfy its specific conditions.
The proposed investment must meet the applicable minimum threshold and expenditure requirements, and the company must comply with shareholding, capital, financing and corporate requirements.
For newly established projects, the BOI generally requires a debt-to-equity ratio not exceeding 3:1.
The investor must demonstrate a credible plan for implementing the proposed activity, including appropriate technology, equipment, processes or professional expertise.
The business must satisfy any applicable standards, environmental requirements, licensing obligations and ongoing conditions.
Is 1 million THB enough for every BOI application? No. Although it is the general minimum project investment threshold, the actual requirements can be considerably higher depending on the proposed business. An eligibility assessment should identify the relevant BOI activity category before determining the required investment amount.

Thailand's BOI programmes cover a wide range of eligible industries and investment activities.
The following sectors may offer opportunities for qualifying foreign-owned businesses.
Selected software development, digital services, technology platforms and other qualifying digital activities.
Manufacturing operations involving advanced machinery, electronics, industrial automation, robotics and related technologies.
Eligible investments involving electric vehicles, automotive components, battery technologies and related manufacturing activities.
Qualifying medical technology, biotechnology, research and development and selected healthcare-related industries.
Advanced agricultural technology, qualifying food processing, renewable energy and selected environmentally focused projects.
Certain international business centre activities, engineering services, logistics, technical services and other qualifying high-value business operations.
Not necessarily. BOI eligibility depends on the exact activity carried out by the company, not simply the industry in which it operates. For example, a company using software for ordinary business operations is not necessarily eligible under a software development category.
Likewise, general consultancy, retail, ordinary trading and conventional service businesses should not be assumed to qualify. Voyage+ assesses the proposed activities against the relevant BOI promotion categories before recommending an application route.
Up to 13 Years
Corporate income tax exemptions
Only for qualifying projects. The duration and scope depend on the approved activity and incentive group; certain advanced innovation projects may qualify for up to 13 years, while other promoted activities may receive shorter exemptions, reductions or non-tax privileges instead.
Depending on the approved project, incentives may include:
No. BOI promotion does not automatically exempt the entire company from corporate income tax. Tax privileges generally apply to qualifying income or activities associated with the approved project, subject to the applicable conditions.
Companies operating both promoted and non-promoted activities may need to distinguish the income and expenses attributable to each. Professional tax and accounting advice is important when evaluating the financial implications of an investment.
Bringing international expertise to Thailand
BOI-promoted companies may benefit from special administrative procedures for employing eligible foreign executives, specialists and skilled personnel.
Foreign Executives
Management positions needed during establishment and operation of the Thai business.
Skilled Professionals
Technical specialists and qualified personnel for approved positions.
Visa & Work Permit Coordination
Applications through the Single Window for Visa and Work Permit procedures.
Subject to approval, the relevant procedures may cover:
Can a foreign shareholder work in their BOI company?
Potentially, yes. However, owning shares in a BOI-promoted company does not automatically provide the right to work in Thailand. The relevant position, individual qualifications, visa status and work authorisation must satisfy the applicable requirements.
At Voyage+, we assist with coordinating the relevant immigration documentation and administrative processes for eligible foreign personnel. Executives planning a long-term stay may also consider the LTR Visa.

Request a Personalised Consultation →The overall cost depends on:
Government charges, third-party costs and consultancy fees should be assessed separately.
Not every foreign-owned business needs or qualifies for BOI promotion.
Depending on the proposed activity, alternative business establishment routes may be available under Thailand's ordinary company registration and foreign business regulatory framework. These may involve different foreign ownership, licensing, capital and employment requirements.
Where BOI promotion is not appropriate, Voyage+ can help you understand the available alternatives and coordinate further assessment with the relevant professionals.
Our objective is to help you identify a suitable and legally compliant business structure, rather than recommend BOI promotion where the proposed investment does not meet the applicable criteria.

We help organise the administrative steps involved in establishing a Thai company and obtaining the necessary approvals.

Foreign ownership, minimum investment, tax exemptions, timing and work permits.
Still have a question? Contact us →Yes, full foreign ownership is permitted for certain BOI-promoted activities. However, eligibility depends on the applicable activity category, foreign business regulations and any conditions imposed by the BOI.
The general minimum qualifying project investment is 1 million THB, excluding land and working capital. Some activities have different minimum investment or personnel expenditure requirements.
Potentially. Eligibility depends on the proposed activity and its specific conditions. Being a startup does not automatically establish eligibility or exemption from the investment requirements.
Certain software development, digital platform and technology activities may qualify. Requirements vary according to the exact business activity, personnel, technology and expenditure conditions.
No. Tax privileges depend on the approved activity and incentive category. Some projects receive corporate income tax exemptions, while others may qualify for different tax or non-tax benefits.
Eligible BOI-promoted companies may obtain approvals for qualifying foreign executives and specialists. Separate approvals and immigration or work authorisation procedures are required.
Not necessarily. Depending on the application circumstances, BOI assessment may begin before incorporation. The required corporate registration and supporting documents must be completed at the appropriate stage before the promotion certificate is issued.
The BOI publishes project evaluation periods of 40, 60 or 90 working days, depending on investment value. The total timeline can be longer when document preparation, company formation and certificate issuance are included.
Yes. Existing businesses may be eligible to apply for qualifying new investment projects, expansions or relevant investment promotion measures, subject to the applicable conditions.
No. BOI investment promotion, corporate registration and any applicable business authorisation are distinct processes. The company must satisfy all relevant legal and regulatory requirements.
Ordinary restaurant, retail and trading activities should not be assumed eligible for BOI promotion. The exact proposed activity must be assessed against the official list of eligible investment activities and any available special measures.
