Anti-Nominee Shareholder Laws in Thailand:
Penalties and Legal Alternatives

1. What is a Nominee Shareholder? The Problem and Its Significance in Thai Law

In the context of Thai law, a "nominee shareholder" refers to a Thai national who holds shares in a company on behalf of a foreign national (alien), without being the true beneficial owner of those shares. The Thai shareholder is a nominal holder only — the foreign principal retains actual control over the investment and receives the real economic benefit, using the Thai shareholder as a "shell" to make the company appear to be a Thai entity and thereby conduct business that the Foreign Business Act (FBA) prohibits or restricts foreign nationals from operating directly.

The nominee problem arises because the Foreign Business Act B.E. 2542 (1999) (พระราชบัญญัติการประกอบธุรกิจของคนต่างด้าว พ.ศ. 2542) prescribes schedules of business activities that are prohibited or restricted for foreign nationals operating in Thailand — most notably List 3, which covers a broad range of service businesses, retail operations, and other commercial activities of significant interest to foreign investors. The use of nominee arrangements is therefore an attempt to circumvent these statutory restrictions.

2. Applicable Law FBA Section 36 and Simulated Transactions under the Civil and Commercial Code

2.1 Foreign Business Act B.E. 2542 (1999) — Section 36

Section 36 of the Foreign Business Act B.E. 2542 (1999) (พระราชบัญญัติการประกอบธุรกิจของคนต่างด้าว พ.ศ. 2542 มาตรา 36) provides that a Thai national or a non-foreign juristic person who assists, participates in conducting a business, or holds shares on behalf of a foreign national shall be subject to imprisonment of not more than three years, or a fine of one hundred thousand to one million baht, or both.

2.2 Civil and Commercial Code — Simulated Transactions (นิติกรรมอำพราง)

In addition to the FBA, a nominee arrangement may constitute a simulated transaction (นิติกรรมอำพราง / disguised act) under Section 155 of the Civil and Commercial Code (ประมวลกฎหมายแพ่งและพาณิชย์ มาตรา 155), which provides that "a declaration of intention made in collusion with the other party as a pretence is void; but such voidness cannot be set up against a third party acting in good faith who would be prejudiced thereby."

In the nominee context, the relationship between the foreign principal and the Thai nominee constitutes a "collusive pretence" — an outward representation that the nominee is the true owner of the shares, while in reality beneficial ownership remains with the foreign party. Such a transaction may be void in its entirety under Section 155, with the effect that all share transfers, related contracts, and corporate acts performed in the name of the nominee company may be without legal force.

3. DBD Enforcement Orders 2025 — Stricter Measures Department of Business Development — Enhanced Anti-Nominee Enforcement

The Department of Business Development (กรมพัฒนาธุรกิจการค้า / DBD) issued new directives and measures in 2025 (B.E. 2568) to intensify the detection and suppression of nominee arrangements within the Thai corporate system. The key measures introduced are as follows.

1. Active Investigation of Shareholding Structures: DBD has intensified scrutiny of companies where foreign shareholding is close to the statutory ceiling of 49%, analyzing the relationships between shareholders and voting patterns at general meetings to identify de facto foreign control.
2. Beneficial Owner (BO) Registry Enforcement: Strict enforcement of Beneficial Owner disclosure requirements, compelling companies to disclose their Ultimate Beneficial Owners (UBO) to prevent concealment of true controlling interests behind nominal Thai shareholders.
3. Whistleblower Channel: A protected whistleblower channel has been established for members of the public to report nominee arrangements, with protections for informants. This significantly increases the exposure risk for companies using nominee structures.
4. Cross-Agency Data Sharing: DBD coordinates with the Revenue Department (กรมสรรพากร), the Anti-Money Laundering Office (สำนักงาน ปปง.), and the Central Investigation Bureau (กองบัญชาการตำรวจสอบสวนกลาง) to cross-reference data relevant to nominee detection.
5. Enhanced Administrative Sanctions: DBD has authority to suspend the operations of companies where nominee use is detected and to refer cases to investigating officers for criminal prosecution.
6. Revocation of Foreign Business Licenses: Where a company holding a Foreign Business License (FBL) is found to be operating through a nominee structure, its FBL may be revoked — rendering the entire business operation retrospectively unlawful.

4. Penalties Criminal, Civil, and Administrative Consequences

Penalties for nominee shareholder arrangements in Thailand span criminal, civil, and administrative dimensions, as summarized in the table below.

5. Red Flags — Indicators Scrutinized by DBD Behavioral Patterns That Signal a Nominee Structure

DBD and related enforcement agencies apply a set of "red flag" indicators to identify nominee shareholding structures. The following conduct patterns are subject to active scrutiny.

6. Legal Alternatives for Foreign Investors BOI Promotion, Treaty of Amity, IBC, and Foreign Business License

Rather than resorting to nominee arrangements — which carry serious criminal and civil exposure — foreign investors have several lawful routes to conduct restricted business activities or achieve full ownership in Thailand. The principal options are as follows.

6.1 BOI Investment Promotion

Enterprises that receive promotion from the Board of Investment (BOI) (สำนักงานคณะกรรมการส่งเสริมการลงทุน) under the Investment Promotion Act B.E. 2520 (1977) (พระราชบัญญัติส่งเสริมการลงทุน พ.ศ. 2520) are exempt from the restrictions of the Foreign Business Act for their promoted activities. This allows a foreign investor to hold 100% of the equity in a BOI-promoted company without requiring any Thai nominee shareholders. BOI promotion is particularly suitable for businesses in the BOI's targeted industry groups — including electronics, automotive, digital technology, agriculture and food processing, healthcare, and advanced manufacturing.

6.2 Thai-US Treaty of Amity (Treaty of Amity and Economic Relations)

The Treaty of Amity and Economic Relations between the Kingdom of Thailand and the United States of America B.E. 2509 (1966) (สนธิสัญญาทางไมตรีและความสัมพันธ์ทางเศรษฐกิจระหว่างราชอาณาจักรไทยและสหรัฐอเมริกา พ.ศ. 2509) grants US-nationality companies (those majority-owned by US nationals, i.e., holding more than 50% of shares) the right to conduct business in Thailand on substantially the same terms as Thai companies. This provides an exemption from nearly all FBA List 3 restrictions, allowing US-owned companies to operate in the majority of commercial sectors without Thai nominee shareholders or a Foreign Business License.

6.3 International Business Center (IBC)

An International Business Center (IBC) is a BOI-promoted corporate structure designed for multinational companies seeking to establish a regional headquarters (Regional HQ) in Thailand. The IBC regime provides a package of special privileges: reduced personal income tax rates for qualifying expatriate employees, Corporate Income Tax exemptions or reductions on qualifying income from affiliated overseas entities, enhanced work permit facilitation, and exemption from FBA restrictions for qualifying IBC activities. This structure is most appropriate for multinational companies of mid-to-large scale generating qualifying revenue from foreign subsidiaries or affiliates that meets the BOI's minimum threshold criteria.

6.4 Foreign Business License (FBL)

Foreign nationals wishing to conduct business activities on FBA Lists 2 or 3 may apply directly for a Foreign Business License (ใบอนุญาตประกอบธุรกิจของคนต่างด้าว) from the Foreign Business Committee under the Council of State (for List 2 activities) or from the Department of Business Development (for List 3 activities). While the process takes time and requires demonstrating tangible benefits to Thailand, an FBL is a fully lawful route that carries no criminal risk and provides the investor with a clear, documented right to operate.

7. Case Studies (Anonymized) Illustrative Cases — All Identifying Information Removed

Case X — Foreign Online Services Company

Company X (incorporated in Country A) wished to operate an online services business in Thailand — a category falling within FBA List 3. The company incorporated a Thai juristic person with two Thai nationals, Persons B and C (employees of the foreign parent company), holding 51% of the shares, while the foreign investor held 49%. A shareholders' agreement was executed granting the foreign party de facto control over all management decisions and profits.

DBD subsequently detected irregularities through analysis of the voting patterns at general meetings and the absence of any genuine dividend payments to the Thai shareholders. The company faced criminal investigation, business operations were suspended, and the foreign investor incurred substantial legal costs. This case illustrates that the true cost of a nominee arrangement — encompassing legal fees, fines, business disruption, and the risk of criminal prosecution — typically far exceeds the cost of obtaining a Foreign Business License or BOI promotion at the outset.

8. Key Recommendations Practical Guidance for Foreign Investors and Thai Shareholders

1. Audit your current structure first: If your company has a shareholding structure that may be characterized as a nominee arrangement, consult qualified legal counsel immediately to assess the risk profile and identify a remediation path before DBD initiates a formal investigation.
2. Restructure through BOI or Treaty of Amity promptly: If the investor qualifies for BOI promotion or Treaty of Amity status, initiate the restructuring process without delay to eliminate criminal and civil exposure from the existing structure.
3. Do not use a general power of attorney: Avoid granting any power of attorney that gives a foreign national comprehensive control over a Thai company. This is the most visible red flag in a DBD review and will almost always trigger further investigation.
4. Thai shareholders must be genuine beneficial owners: Thai shareholders must invest genuine capital, make independent business decisions, and receive actual economic benefits proportionate to their shareholding. Nominal shareholders who contribute nothing but their name satisfy neither the law nor regulatory scrutiny.
5. Maintain full Beneficial Owner disclosure: Comply rigorously with the DBD's Beneficial Owner reporting requirements. Accurate disclosure of Ultimate Beneficial Owners is a legal obligation, and non-compliance is itself a sanctionable offense.
