Quick Answer
The Amity Treaty benefits in Thailand allow US citizens and US-majority-owned companies to hold 100% foreign ownership of a Thai business and operate with national treatment, bypassing most restrictions under the Foreign Business Act.
These privileges give American investors greater control, simplified market entry, and access to business activities typically restricted to foreign nationals. Herrera & Partners assists US investors in structuring Amity Treaty companies, obtaining certification, and maintaining long-term compliance.
What Is the US-Thailand Treaty of Amity?
The Treaty of Amity and Economic Relations between Thailand and the United States was signed in 1966 and came into effect in 1968. It establishes a preferential framework for American citizens and businesses operating in Thailand.
The treaty’s core principle is national treatment. This means US-owned companies receive the same legal standing as Thai-owned businesses in most commercial activities. For American investors, this removes significant barriers that apply to other foreign nationals under Thai law.
Key Amity Treaty Benefits
Full Foreign Ownership
Under standard Thai regulations, foreign investors are limited to 49% ownership in most business structures. The Amity Treaty overrides this restriction for qualifying US companies.
American citizens and US-majority-owned entities can hold up to 100% of shares in a Thai limited company. This provides complete control over business decisions, strategy, and profit distribution without requiring a Thai partner.
National Treatment Status
Treaty-protected companies operate on the same legal basis as Thai-owned businesses. This status grants access to rights and privileges normally reserved for Thai nationals, including participation in business activities restricted under the Foreign Business Act.
Exemption from Foreign Business Act Restrictions
The Foreign Business Act restricts foreigners from engaging in over 50 categories of business activities in Thailand. Companies certified under the Amity Treaty are exempt from most of these restrictions.
Upon receiving a Foreign Business Certificate, American-owned companies can undertake activities that would otherwise require special licensing or be entirely prohibited for foreign entities.
Simplified Market Entry
While paperwork is still required, the Amity Treaty process is generally more streamlined than obtaining a standard Foreign Business Licence. US investors benefit from a defined certification pathway through the US Commercial Service and Thai Ministry of Commerce.
Expanded Business Opportunities
American businesses can engage in commercial ventures often closed to other foreign companies. This includes professional services, consulting, trading, distribution, manufacturing, and technology services, among others.

What the Amity Treaty Does Not Provide
Understanding the treaty’s limitations is equally important. The Amity Treaty offers ownership and operational benefits but does not grant certain privileges.
The treaty does not provide:
- Tax exemptions or incentives (standard Thai corporate tax rates apply)
- Visa or work permit privileges (standard immigration rules apply)
- Land ownership rights (Amity companies cannot directly own land)
- Access to all business sectors (certain activities remain restricted)
American-owned companies remain subject to corporate income tax at 20%, value-added tax at 7%, and withholding tax on dividends and royalties. US investors seeking tax incentives may need to explore BOI promotion as a complementary structure.
Restricted Activities Under the Amity Treaty
While the treaty grants broad rights, certain sectors remain off-limits. These restrictions mirror those in List 1 of the Foreign Business Act.
Prohibited activities include:
- Communications and inland transportation
- Commercial banking and fiduciary functions
- Exploitation of land and natural resources
- Domestic trade in indigenous agricultural products
- Certain professional services reserved for Thai nationals
American businesses seeking to operate in these sectors must comply with standard foreign investment regulations or seek alternative structures such as BOI promotion.
Eligibility Requirements
To qualify for Amity Treaty benefits, companies must meet specific ownership and management criteria.
Ownership requirements:
- At least 51% of shares held by US citizens or US-incorporated companies
- US majority ownership must be maintained at all levels of the corporate structure
Management requirements:
- At least 50% of directors must be US or Thai citizens
- Directors of other nationalities must co-sign with a US or Thai director
Capital requirements:
- Minimum registered capital of THB 2 million
These conditions ensure the company is genuinely American-owned and controlled rather than a nominal structure.
How to Obtain Amity Treaty Certification
The certification process involves coordination between US and Thai authorities.
Step 1: Incorporate a Thai limited company Register the company with the Department of Business Development. The shareholding structure must already reflect US majority ownership.
Step 2: Obtain US Commercial Service certification Submit notarised documentation to the Commercial Service Office at the US Embassy in Bangkok. Required documents include proof of US citizenship or corporate ownership, director details, and shareholding information.
Step 3: Apply for Foreign Business Certificate After receiving US certification, submit the application to the Thai Department of Business Development. Upon approval, the company receives a Foreign Business Certificate confirming its treaty-protected status.
The entire process typically takes 4 to 8 weeks depending on document preparation and authority review timelines.
Amity Treaty vs BOI Promotion
The Amity Treaty and BOI promotion serve different purposes and are sometimes confused.
|
Aspect |
Amity Treaty |
BOI Promotion |
|
Focus |
Ownership and market access |
Tax incentives and investment promotion |
|
Eligibility |
US investors only |
Multiple nationalities |
|
Tax benefits |
None |
Corporate tax exemption up to 13 years |
|
Ownership |
100% foreign permitted |
100% foreign permitted |
In some cases, both frameworks can coexist. A US investor may establish an Amity company for ownership rights while also applying for BOI promotion to access tax incentives. This requires careful structuring to avoid regulatory conflicts.
