Understanding the Foreign Business Act, an unavoidable act for foreign businesses

The Foreign Business Act B.E. 2542 (FBA), enacted in 1999, regulates foreign involvement in Thai enterprises. It establishes guidelines for international participation in economic activities, confirming some sectors remain under Thai control. The Act plays a pivotal role in shaping the investment climate and balancing commercial openness with national priorities.

Thailand, as a rapidly modernizing economy, has historically attracted significant overseas capital. However, concerns over economic sovereignty, national security, and equitable competition led to limitations on non-national possession in strategic domains. The FBA aims to safeguard local companies, making sure Thai people maintain control over essential industries, and prevent foreign monopoly.
Fundamentally, the FBA embodies Thailand’s policy of retaining economic autonomy while welcoming foreign direct investment (FDI) in pivotal sectors benefiting the country. Unlike entirely protectionist policies, the Act does not prohibit all international investment but rather administers it through a structured approval mechanism. This ensures that foreign enterprises align with Thailand’s economic and social evolution goals while still shielding local entrepreneur interests.


The FBA classifies businesses into three types: those expressly forbidden to outsiders, those requiring exceptional permission, and those permitted with conditions. The Department of Business Development (DBD) under the Ministry of Commerce enforces the Act, and violations may result in severe penalties, like fines and incarceration.
 The main goals of this legislation are:

  • Preserving national sovereignty by restricting foreign control over industries vital to Thailand’s economy and security.
  • Maintaining economic stability by preventing foreign monopolization of key sectors.
  • Ensuring fair competition by providing a level playing field for Thai-owned businesses.
  • Regulating foreign participation through a licensing system for restricted business activities.

How the Foreign Business Act Limits the foreign participations in Thai Businesses

Key Restrictions under the FBA

The Foreign Business Act mandates stringent stipulations on international involvement in Thai enterprises, narrowly confining admittance to over 50 exclusive sectors.
Under the FBA, an organization is considered internationally owned if no less than half of its shares are retained by overseas persons or foreign bodies. The characterization is exclusively founded on property rights, rather than effective control.
Foreign corporations aspiring to perform in limited domains must obtain a Foreign Business License (FBL). Many foreign investors circumvent these restrictions by setting up companies with majority Thai ownership, while structuring the company in a way that still allows them to retain operational control. This is commonly done through preference shares and weighted voting rights. However, the use of nominee shareholders is strictly prohibited under the FBA. A nominee shareholder is a Thai national who holds shares on behalf of a foreign entity without actual ownership or decision-making power.

The Definition of a Foreign Business Under the Foreign Business Act

Determining who is considered foreign under the Foreign Business Act is essential for investors planning to enter Thailand’s market. Section 4 of the FBA defines a foreigner in four ways:

  • A natural person without Thai citizenship.
  • A company registered outside Thailand.
  • A juristic person registered in Thailand where at least 50% of the shares are held by foreign nationals or foreign entities.
  • A Thai-registered company controlled by foreigners in management.
    If an entity fits any of these descriptions, it must abide by the FBA’s limitations and acquire the proper licenses before conducting restricted operations.

Restrictive Ownership Rules for Foreign Investors in Thai Companies

The Foreign Business Act restricts foreigners from owning more than 49.99% of companies involved in regulated industries unless granted an Foreign Business License or promoted by the Board of Investment. A company less than half foreign-owned is viewed as Thai and escapes the FBA’s constraints.
However, even in Thai majority-held companies, foreigners can control them through preference shares giving extra voting power, disproportionate votes, or management contracts. Foreign investors must ensure compliance with Thai corporate law, especially regarding prohibited nominee shareholderships, which disguise true ownership.

The three list of Restricted Business Activities under the FBA

The FBA classifies restricted sectors into three categories:

  • List 1: Includes industries that are completely prohibited for foreigners due to national security or cultural importance (e.g., media, agriculture, land trading).
  • List 2: Allows foreign companies to operate in industries affecting security, resources, or Thai tradition only with Cabinet approval, such as domestic transport and mining.
  • List 3: Encompasses industries where Thai businesses are not yet ready to compete with foreign enterprises such as legal services, accounting, and advertising.

Foreigners can engage in these activities by obtaining a Foreign Business License from the Department of Business Development.

Penalties and Prohibited Activities Under the Foreign Business Act 

Main prohibitions under the Foreign Business Act

The Foreign Business Act contains strict prohibitions and penalties to deter non-compliance. One of the main prohibitions is nominee shareholding arrangements. The situation where a Thai national holds shares on behalf of a foreign investor without actual control or ownership, is explicitly prohibited as they undermine ownership restrictions. Authorities closely monitor companies for suspicious nominee structures, especially disproportionate financial agreements lacking genuine investment from Thai shareholders.

Instead of nominees, foreign investors are advised to use preference shares with enhanced voting rights or joint ventures with legitimate Thai partners to ensure legal compliance.
Failure to meet prescribed minimum capital levels for foreign enterprises also violates the Act. Additionally, operating a business without a license in a restricted sector is prohibited by Section 6, 7, 8 of the Foreign Business Act.

The FBA delineates a structured appeals procedure outlined in Section 20, where a foreign entity denied a business license can submit an appeal to the Ministry of Commerce. Nevertheless, the Minister’s ruling is conclusory and binding.

Main Penalties under the Foreign Business Act

Violations of the FBA lead to severe penalties, as outlined in Sections 34-38:

  • Imprisonment for up to three years for operating without permission.
  • Fines ranging from 100,000 to 1,000,000 Thai Baht.
  • Daily fines of up to 50,000 Baht for continued violations.
  • Forced closure of the business upon court orders.

Furthermore, Section 36 of the Foreign Business Act criminalizes nominee shareholding arrangements, imposing severe penalties on both the foreign investor and the Thai nominee, including business closure, deportation, fines up to 1 million baht per day, and imprisonment of up to 3 years.
Strict adherence to the Foreign Business Act is necessary to avoid its severe prohibitions.

The Foreign Business License

Foreign companies can function in prohibited sectors with a Foreign Business License, allowing flexibility in working around the FBA’s restrictions.
Gaining a Foreign Business License from the Department of Business Development under the Ministry of Commerce represents a pivotal step for foreign entities hoping to operate in restricted sectors covered by the Foreign Business Act. Issuance demands meeting several criteria and submitting specific documents:

  • Eligibility Check: the process starts with validating eligibility by checking if a planned venture falls under List 2 or List 3 of the Foreign Business Act
  • Application Submission: Applications are submitted to the Department of Business Development (DBD) under the Ministry of Commerce. It must include a comprehensive business strategy outlining the nature and extent of operations, monetary statements and evidence of registered capital, with a lowest threshold of THB 3 million. Additionally, details demonstrating benefits to Thailand through means such as knowledge sharing, job generation, or contributions to domestic markets have to be included.
  • Approval Process: the list 2 activities require Cabinet approval. The review process involves consultations with relevant ministries to evaluate whether the proposed business aligns with national security and economic objectives. However, the list 3 activities require approval from the Foreign Business Committee (FBC). The FBC evaluates the potential economic impact and ensures the business’s adherence to local laws.
  • Capital requirement: The minimum registered capital for most ventures is THB 3 million, though higher floors may apply for certain industries. Large-scale initiatives frequently have capital demands surpassing THB 100 million.
  • Timeline Considerations: Authorities typically review submissions for two to four months, although intricate schemes may prolong examination. Candidates must stand prepared to furnish supplementary filings if necessary.
    FBL holders are obligated to employ a minimum number of Thai nationals contingent on field. Moreover, they consistently must sustain precise books and annually deliver reports to the DBD. Ultimately, they have to conform to any extra conditions outlined in the permit.

Conclusion

Thailand offers vast chances for overseas financiers, but it also imposes strict rules under the Foreign Business Act. While numerous activities remain restricted, foreign companies can still legally operate by securing a Foreign Business License or structuring their entities in compliance with Thai law. Understanding the intricacies of the FBA, such as ownership thresholds, prohibited activities, and licensing requirements, is essential for foreign businesses aiming to successfully navigate the Thai regulatory environment. Engaging with legal professionals who specialize in Thai corporate law can significantly streamline the process and reduce legal risks associated with non-compliance.
