Foreign business ownership in Thailand is regulated by the Foreign Business Act, which restricts certain sectors but still allows 100% foreign ownership through legal structures such as BOI promotion, export businesses, manufacturing companies, or a Foreign Business Licence. Understanding these rules helps foreign investors structure their company correctly and avoid compliance risks when entering the Thai market.
Introduction:
For many entrepreneurs, the question of foreign business ownership in Thailand is an important one. While many business activities in Thailand require a Thai shareholder to hold a majority ownership of more than 50 percent under the Foreign Business Act Thailand, there are several legal structures and investment pathways that permit 100 percent foreign ownership.
Thailand remains one of Southeast Asia’s most attractive destinations for foreign investors. However, foreign business ownership is regulated by the Foreign Business Act Thailand (FBA). The FBA sets out which activities are restricted, which require special permission, and which may be undertaken with majority or full foreign ownership. Without proper legal planning, investors may face business restrictions or delays to market entry.
In this complete 2026 guide, we explain how foreign ownership rules operate in practice, when 100 percent foreign ownership is possible and how to structure your business correctly.
Key Points
- The Foreign Business Act (FBA) restricts around 50 categories of business activity, dividing them into three lists ranging from strictly prohibited sectors to those where a foreign business licence can be applied for.
- 100% foreign ownership is possible through two main routes: a BOI promotion (which also unlocks tax incentives and simplified work permits) or a Foreign Business Licence, though the latter is harder to obtain and approval is not guaranteed.
- BOI promotion is generally the preferred route for eligible businesses, offering corporate income tax exemptions of up to 13 years, import duty exemptions, land ownership rights, and a clearer approval framework than the Foreign Business Licence process.
- Nominee shareholder arrangements are illegal and increasingly prosecuted, with Thai authorities actively cross-checking company registrations against Revenue Department records to identify structures where Thai shareholders hold shares on behalf of foreign investors without genuine financial interest.
- Enforcement of the FBA has significantly intensified in 2024–2025, with authorities scrutinising shareholding structures, voting rights arrangements, and preference share allocations that may disguise effective foreign control, exposing both foreign investors and Thai nominees to fines, imprisonment, and company dissolution.
What Is the Foreign Business Act and Why Does It Restrict Foreign Ownership in Thailand?
The Foreign Business Act, formally known as the Foreign Business Act B.E. 2542 (1999), is the primary legislation governing foreign business ownership in Thailand. The Foreign Business Act Thailand was introduced to protect certain sectors for Thai nationals while continuing to welcome foreign investment into areas that support economic development.
The Foreign Business Act is used to determine whether a business activity is restricted, whether a licence may be granted, and whether a company structure complies with Thai law.
Who Is Considered a “Foreigner” Under the FBA?
Section 4 of the foreign business act Thailand has a wide definition of what is considered a “foreigner” The definition extends beyond nationality and covers both individuals and juristic persons. A foreigner includes:
- A natural person who is not of Thai nationality.
- A juristic person not registered in Thailand.
- A juristic person registered in Thailand where at least 50 percent of the capital shares are held by non-Thai individuals or foreign entities, or where foreign investment represents at least half of the total capital.
- A Thai-registered juristic person in which at least half of the shares are held by persons falling within the above categories, directly or indirectly.
- A limited partnership or registered ordinary partnership where the managing partner is a non-Thai national.
The Three Restricted Business Lists
The foreign business act Thailand restricts approximately 50 categories of business, divided into three schedules:
List 1 – Strictly Prohibited Activities
List 1 covers businesses considered essential for national interests, such as newspaper publishing, animal farming, land trading, and certain agricultural activities. Foreigners are prohibited from engaging in these activities for “special reasons.” No licence or approval mechanism is available.
List 2 – Activities Related to National Security and Infrastructure
List 2 includes businesses connected to national security, domestic transportation by land, water, or air, and certain activities involving arts, culture, and natural resources. Foreign participation may be permitted, but only with approval from the Minister of Commerce and the Cabinet. In practice, such approvals are rare and subject to strict scrutiny.
List 3 – Service Businesses Where Thai Nationals Are Deemed Not Ready to Compete
List 3 is the most commercially relevant category for foreign investors. It includes “other categories of service businesses” not otherwise exempted by ministerial regulations. Foreign companies may apply for a Foreign Business Licence, subject to approval by the Director-General of the DBD and the Foreign Business Committee. Many professional services, consulting, and trading structures fall within this list.
Business Activities that Allow 100% Foreign Ownership Without Special Permissions
The following business activities are not restricted under the Foreign Business Act in Thailand and can be undertaken by a 100% foreign owned business.
Export Companies
Thailand actively encourages exports, and companies who exclusively export products outside Thailand can be foreign owned. In order to maintain this status, export companies must ensure their operations and revenue are only international, and they can’t sell directly within the Thai domestic market.
Manufacturing Companies
Manufacturing companies in Thailand can be 100% foreign-owned as manufacturing is not on Thailand’s “restricted” list for foreign ownership under the Foreign Business Act (FBA). This allows foreign investors to own and operate manufacturing businesses without needing a Thai partner.
Another advantage for manufacturing companies is their eligibility for a BOI promotion. BOI promotions offer many advantages including different types of tax exemptions including Corporate Income Tax exemptions and Tax exemptions on the import of machinery. BOI promotions can also allow full foreign ownership and the ability to own land which can be used for their factory etc.
However, if the manufacturing business involves activities related to restricted sectors (e.g., agriculture, mining, certain types of food processing), it may still be subject to FBA limitations.
Common Misconceptions About Foreign Ownership
There is a common misunderstanding that incorporating a Thai company automatically allows majority foreign ownership. However, if the business activity falls within a restricted list, foreign majority ownership may require the foreign investor to apply for a Foreign Business licence or an alternative option such as a Board of Investment (BOI) promotion. In practice, most of the business activities that foreign investors wish to undertake are likely to be restricted by the foreign business act.
If the business cannot obtain either a Foreign Business Licence or BOI promotion and wishes to engage in a restricted activity, the foreign investor will have to work with a Thai partner.
Another misconception is that nominee shareholding arrangements can be used as an easy way to bypass these restrictions. However, recently Thai authorities have increased scrutiny of structures designed to conceal effective foreign control. The DBD has strengthened investigations into shareholder legitimacy, capital flows, and voting rights arrangements, particularly during 2024 and 2025.
Enforcement Trends and Penalties
Thai authorities are now actively examining whether Thai shareholders are genuine investors or merely holding shares on behalf of foreigners to avoid the restrictions of the Foreign Business Act.
Non-compliance with the Foreign Business Act in Thailand can result in significant consequences, including fines, imprisonment, suspension of operations, and in severe cases, business closure. Directors may also face personal liability if they knowingly participate in unlawful structures.

How to Get a Foreign Business License in Thailand
A Foreign Business License (FBL) is a formal approval issued to foreign investors or foreign-owned companies that wish to carry out business activities restricted under the Foreign Business Act.
In Thailand, certain sectors are reserved for Thai nationals or Thai majority-owned companies. Where an activity is considered as restricted under the Foreign Business Act, a foreign company cannot undertake this activity. An FBL is required to obtain lawful permission to operate in those sectors.
The Foreign Business Licence is formal approval confirming that a foreign company is authorised to engage in a restricted business activity. Without it, undertaking a restricted activity may expose the company and its directors to administrative penalties and potential criminal liability.
While a Foreign Business License may appear to be an attractive option, it is not automatically available to all companies. The application process is strict, requiring detailed supporting documentation, clear justification of the proposed business activity, and evidence of the economic benefit or transference of technology to Thailand.
Approval is not guaranteed and in practice, very few Foreign Business Licences are awarded. The submission of an application does not guarantee that the licence will be granted, and each case is assessed on its individual merits.
How BOI Promotion Gives You 100% Foreign Ownership (Even for Restricted Businesses)
The Thailand Board of Investment (BOI) is a government agency established in 1966 under the Office of the Prime Minister. The aim of the BOI is to promote both foreign investment by granting incentives and regulatory privileges to projects that support Thailand’s long-term economic development.
BOI incentives are divided into 2 distinct groups, general business benefits and tax incentives.
General Business Benefits
- 100% Foreign Ownership
BOI-promoted activities may permit up to 100% foreign ownership, including in sectors that would otherwise be restricted under the Foreign Business Act. - Land Ownership
BOI companies can own 1 Rai, certain BOI promotions for specific business activities are allowed to own larger plots of land. - Reduced Work Permit Requirements
BOI companies benefit from streamlined visa and work permit procedures and are exempt from the standard 4:1 Thai-to-foreign employee ratio typically applicable to non-promoted companies. - R&D and Import Privileges
Import duty exemptions may apply to machinery, raw materials, and goods used for research and development.
Tax Incentives
- Corporate Income Tax Exemption
CIT exemptions may be granted for up to 13 years, depending on the business activity and location. Some zones provide additional years of exemption. Not all promoted activities qualify, and the duration depends on the specific category awarded. - Import Duty Exemptions
Exemptions may apply to machinery and raw materials used in export-oriented manufacturing. - Post-Holiday Reduction
A 50% reduction in CIT may be granted for up to 10 years following the expiry of the tax exemption period.
Can Foreigners Own 100% of a Business in Thailand? The BOI and the Foreign Business Certificate
A significant advantage of BOI promotion is the ability for a foreign investor to be able to apply for a Foreign Business Certificate (FBC) under Section 12 of the Foreign Business Act. The FBC allows a foreign owned company to undertake restricted activities covered by its BOI promotion without applying for a separate Foreign Business Licence.
Once the BOI Promotion Certificate is issued, the company may apply to the Ministry of Commerce for the FBC. While the Ministry retains discretion, the certificate is in practice always granted for the approved promoted activities.
By obtaining a BOI promotion, the company promoted this additional regulatory layer, making it a more structured and predictable route for eligible foreign investors entering restricted sectors.
BOI vs Foreign Business Licence (FBL)
The decision between a BOI promotion and a Foreign Business Licence should be based on the nature of the business activity, the level of investment, and the company’s long-term objectives in Thailand.
BOI Promotion
A BOI promotion is generally most appropriate where the proposed activity falls within eligible promoted categories and the investor seeks to secure up to 100% foreign ownership. However, companies must carefully consider the prescribed minimum investment thresholds and operational conditions imposed by the BOI, as these requirements may not be achievable for all types of business.
For eligible projects, a BOI promotion can offer significant advantages, particularly where corporate income tax incentives, import duty exemptions, and reduced requirements for work permit processes are required
Foreign Business Licence
A Foreign Business Licence may be suitable where the activity does not qualify under BOI criteria or where the company is acquiring or operating an existing business structure. It is typically considered when investment levels fall below BOI thresholds or when the main requirement is to obtain legal permission to conduct a restricted activity under the Foreign Business Act, rather than to obtain tax incentives.
Historically, many lawyers and advisors in Thailand have described the Foreign Business Licence (FBL) process as relatively unpredictable, often suggesting that approval could be uncertain and sometimes informally characterised as having roughly a “50-50” chance of success depending on the circumstances of the application. For this reason, practitioners have traditionally encouraged investors to pursue a Board of Investment (BOI) promotion whenever the activity qualifies, as BOI approval generally provides a more structured approval framework together with additional advantages such as tax incentives, land ownership rights, and simplified visa and work permit procedures.
Recently, however, enforcement of the Foreign Business Act has increased, particularly with respect to the improper use of Thai nominee shareholders designed to circumvent foreign ownership restrictions. At the same time, the Ministry of Commerce appears to have adopted a more pragmatic approach in reviewing legitimate FBL applications. Where investors present a genuine business project that satisfies the criteria under the Foreign Business Act, such as contributing technology, expertise, or economic value to Thailand, applications allowing majority foreign ownership (including up to 100% foreign ownership in certain cases) appear to be assessed more pragmatically. In parallel, authorities have become stricter toward structures designed primarily to bypass the law through the use of nominee shareholders.
Why Nominee Shareholders Are Illegal in Thailand
Under the Foreign Business Act B.E. 2542 (1999) (FBA), the use of nominee shareholders to avoid foreign ownership restrictions is strictly prohibited.
A nominee shareholder arrangement arises where a Thai individual or juristic person is registered as a shareholder but does not have a genuine financial interest in the company. The shares are held on behalf of a foreign investor who retains the real economic benefit and effective control.
Nominee structures typically involve one or more of the following characteristics:
- The registered Thai shareholder has not contributed capital or does not have the financial capacity to subscribe for the shares held in their name.
- The Thai shareholder has no beneficial interest in the company and does not exercise genuine decision-making authority.
- The shareholding arrangement is designed to present the company as Thai-majority owned for regulatory purposes.
- Side agreements, loan arrangements, or voting undertakings transfer control or economic benefit to the foreign investor.
Where the above exists in a company structure, Thai authorities are likely to treat the structure as a foreign-owned business operating in breach of the FBA.
Legal Exposure and Enforcement Risk
The FBA imposes significant criminal penalties on both the foreign investor and the Thai nominee. Penalties may include substantial fines, imprisonment, and court-ordered dissolution of the company.
Enforcement activity has intensified in recent years. Thai authorities have increased scrutiny of shareholding structures, particularly in sectors historically associated with nominee risk, including property holding and certain commercial activities. Investigations have included cross-checking corporate registration data with Revenue Department records to identify inconsistencies between declared ownership and economic reality.
Preference Shares and Control Disparities
Foreign investors should also be careful when using preference share structures that disproportionately allocate voting rights, dividend entitlements, or control mechanisms in favour of foreign shareholders.
Under Thai company law, preference share rights are enforceable only if they are expressly provided for in the Articles of Association of the company, which are filed with the Ministry of Commerce and therefore form part of the company’s official public records. In practice, this means that the specific rights attached to each class of shares,such as voting rights, dividend priority, or liquidation preference, must be clearly stated in the Articles.
Because these Articles are filed with the Department of Business Development (DBD), the authorities are able to review the share structure during regulatory inspections or investigations. Where the Articles reveal a structure in which Thai shareholders formally hold the majority of the issued shares but foreign shareholders enjoy disproportionate control rights or economic benefits, the authorities may question whether the arrangement reflects genuine commercial allocation or whether it could constitute a circumvention of the Foreign Business Act through the use of Thai nominee shareholders.
For this reason, in practice many control arrangements are structured through shareholders’ agreements, investment agreements, or joint venture agreements, which remain private contracts between the parties and are not filed with the Ministry of Commerce. In international joint venture structures, it is also common for investors to establish a holding company in a neutral jurisdiction such as Hong Kong, through which the parties organise governance and economic rights. The shareholders’ agreement at the holding company level may govern key matters such as management of the Thai operating company, board appointment rights, reserved matters, and investor protections, while providing for dispute resolution through international arbitration rather than Thai courts.
