What is the U.S.–Thailand Treaty of Amity?
The Treaty of Amity and Economic Relations between the Kingdom of Thailand and the United States of America was signed on May 29, 1966, and came into effect in 1968. The main objective of the treaty is to promote trade, investment, and economic cooperation between the two nations.
One of the treaty’s most significant features is that it allows U.S. citizens and U.S. owned companies to own up to 100% of a business registered in Thailand, bypassing the restrictions set by the Thai Foreign Business Act (FBA) of 1999, which usually limits foreign ownership to 49%.
Key principles of the treaty:
- Equal treatment of American and Thai companies in most business sectors.
- Protection against expropriation without fair compensation.
- Freedom to transfer funds in and out of Thailand without restrictions.
- Exemptions from certain restrictions that apply to other foreign investors.
Benefits of registering a business under the Treaty of Amity
Setting up a company under the Treaty of Amity provides several advantages for American investors in Thailand. Here are the main benefits, explained in detail:
- 100% Foreign Ownership
Under Thai law, most foreign investors are required to have at least 51% of their company’s shares held by Thai nationals or entities. The Treaty of Amity makes an exception for American citizens and businesses, allowing them to own up to 100% of the shares of a Thai limited company. This means that American investors can establish and control their business fully without the need for a local Thai partner, which provides greater autonomy over decision-making, strategy, and profits. - Equal National Treatment
Treaty-protected businesses are legally treated on the same basis as Thai-owned businesses. This ensures that American investors enjoy the same rights, privileges, and protections as Thai nationals. It means U.S.-owned businesses can engage in most commercial activities without being classified as “foreign” under the Foreign Business Act. - Exemption from Foreign Business Licensing Requirements
Foreign-owned companies in Thailand often require a Foreign Business License (FBL) to engage in most business activities. Acquiring an FBL can be a time-consuming and costly process. However, companies certified under the Treaty of Amity are exempt from these licensing requirements in most sectors, allowing for a smoother and faster market entry. - Free Remittance of Profits and Capital
The Treaty guarantees the free flow of capital, allowing American-owned businesses to repatriate profits, dividends, and invested capital without restrictions. This feature is especially attractive for businesses that intend to periodically transfer profits back to the United States. - Protection from Expropriation
The Treaty provides protection against the expropriation or nationalization of American-owned assets by the Thai government without fair compensation. This legal safeguard adds an extra layer of security for American investors concerned about political or regulatory risks.
Restrictions and eligibility criteria under the Treaty Of Amity
While the Treaty of Amity offers significant privileges, there are certain limitations and restrictions. Not every business activity is open to Treaty-certified companies.
Prohibited or restricted business activities:
The following sectors remain off-limits or restricted for Treaty-certified businesses:
- Communications: Includes telecommunications, broadcasting, and related media industries.
- Transportation: Covers domestic transportation, including land and air services.
- Fiduciary Functions: This includes banking, financial services, and securities trading.
- Land Ownership: Companies under the treaty cannot directly own land in Thailand.
- Exploitation of Natural Resources: Covers forestry, mining, and certain environmental resources.
- Domestic Trade in Agricultural Products: Includes retail and wholesale of locally sourced agricultural goods.
For these industries, American businesses must comply with the standard regulations applicable to all foreign investors or seek approval from other relevant Thai authorities, such as the Board of Investment (BOI).
Eligibility criteria for the Treaty of Amity protection?
To qualify for the benefits of the Treaty of Amity, a business must meet specific ownership and management requirements:
- At least 51% of shares must be held by U.S. citizens or U.S.-incorporated companies.
- A majority of directors (at least 50%) must be U.S. citizens.
These conditions ensure that the company is genuinely American-owned and controlled, rather than being a nominal or proxy structure.
Everything you should know to run a Treaty of Amity company
Setting up a business under the Treaty of Amity involves several steps. The process requires careful coordination with Thai government agencies and legal compliance at every stage.
How to set up a Treaty of Amity company in Thailand?
Below is a step-by-step guide to help you navigate the process.
Step 1: Company Registration in Thailand
The first step is to establish a Thai limited company. This involves:
- Choosing a company name.
- Preparing the company’s Memorandum of Association (MOA).
- Registering the company with the Department of Business Development (DBD) under the Ministry of Commerce.
Initially, the company will be treated as a standard Thai limited company until Treaty certification is obtained.
Step 2: Certification by the U.S. Commercial Service
The company must request certification from the U.S. Commercial Service (USCS) at the U.S. Embassy in Bangkok. This involves submitting:
- Company registration documents.
- List of shareholders and directors.
- Corporate structure showing U.S. ownership and control.
The USCS verifies that the company meets the eligibility criteria under the Treaty.
Step 3: Application for Foreign Business Certificate
Once the U.S. Commercial Service certifies the business, the company must apply for a Foreign Business Certificate (FBC) from the Thai Ministry of Commerce. This certificate officially allows the company to operate as a U.S. Treaty company with 100% foreign ownership.
Step 4: Obtain Necessary Licenses (If Required)
For certain regulated activities (e.g., education, health services, finance), additional licenses or permits may be required from relevant authorities.
Timeline for setting up a treaty company
The entire process, from initial company registration to obtaining the Foreign Business Certificate, typically takes between 6 to 12 weeks, depending on the complexity of the business, the responsiveness of the authorities, and the completeness of the documentation.
One significant benefit of operating a Treaty of Amity company is the ability to obtain work permits and long-term visas for American staff and executives.
Visa options
- Non-Immigrant “B” Visa (Business Visa)
- Extension of Stay based on employment with the registered company
Work permit
American citizens employed by the Treaty company can apply for a Thai work permit, which is necessary for legally working in Thailand.
Note: Companies must meet the minimum capitalization and employment requirements to sponsor work permits. Typically, the company must have at least 2 million THB in registered capital per foreign employee.
Taxation for Treaty of Amity companies
While the Treaty of Amity provides ownership and operational benefits, it does not offer tax exemptions. American-owned companies are subject to the same tax rules as Thai businesses, including:
- Corporate Income Tax: 20% on net profits.
- Withholding Tax: On dividends, interest, royalties, and service fees.
- Value Added Tax (VAT): 7% on most goods and services.
U.S. citizens may also need to consider double taxation agreements (DTA) between the United States and Thailand to avoid being taxed twice on the same income.
Ongoing compliance and legal obligations
Treaty companies must maintain compliance with both Thai corporate laws and Treaty conditions:
- Maintain U.S. majority ownership and board composition at all times.
- File annual financial statements and audits with the Department of Business Development.
- Ensure correct tax filings and payments.
- Keep up-to-date on changes in Thai regulations that may affect their operations.
Failure to comply can result in the revocation of the Foreign Business Certificate and Treaty privileges.
Is this treaty the perfect fit for your business?
The U.S.–Thailand Treaty of Amity remains a powerful tool for American businesses seeking to enter or expand in the Thai market. With the ability to own 100% of a business, bypass foreign business licensing, repatriate profits freely, and benefit from equal legal standing, the Treaty provides significant advantages over standard foreign investment routes.
The Treaty of Amity is an excellent solution for American investors who:
- Want to maintain full ownership of a Thai business.
- Operate in sectors not restricted by the treaty.
- Seek the legal protections and equal treatment offered by the Treaty.
It may not be suitable for businesses requiring land ownership or operating in highly regulated industries such as finance or telecommunications.
However, successful implementation requires careful planning, adherence to ownership rules, and ongoing compliance. Engaging a professional service provider with expertise in Treaty of Amity setups can help ensure a smooth and legally compliant market entry.
