What Is a Foreign Business License?
Understanding the Foreign Business Act in Thailand
The Foreign Business Act B.E. 2542 (1999) restricts or prohibits foreign-owned entities from engaging in certain business activities in Thailand without prior authorization from the Department of Business Development (DBD).
A Foreign Business License (FBL) is the official authorization allowing a foreign company to conduct a restricted business activity legally in Thailand. Without it, operating in a restricted category exposes your company to significant legal and financial penalties.
B-Accounting helps foreign investors assess their activities, determine applicable restrictions, and navigate the full FBL application process with the DBD.
Applicable to companies with more than 49% foreign shareholding
Covers List 2 and List 3 restricted activities

Minimum capital requirements apply depending on the activity

- Production of firearms and explosives
- Domestic land transport and warehousing
- Logging and wood processing
- Thai herb and traditional medicine trade
- Tourism businesses (certain categories)

List 3 — DBD Approval Required
The most commonly applicable list for foreign service businesses. Approval is granted by the Director-General of the DBD with the Foreign Business Committee.

Alternatives to an FBL
Other Structures Available to Foreign Investors
Depending on your business activity, nationality and investment profile, alternatives to a full FBL application may be available.
🇺🇸
Treaty of Amity
US nationals and US-majority companies may qualify for national treatment under the US-Thailand Treaty of Amity, allowing majority foreign ownership in most sectors without an FBL.
🏆
BOI Promotion
Companies in eligible sectors may apply for BOI promotion, which grants the right to operate with full foreign ownership and additional tax and non-tax incentives, without requiring an FBL.
🤝
Thai Majority Structure
Establishing a Thai-majority company with a foreign minority interest can allow operation in restricted sectors without an FBL, subject to proper legal structuring and compliance requirements.
🏢
Representative Office
Foreign companies engaged only in non-commercial liaison activities may operate through a Representative Office, which has limited permitted activities but does not require an FBL for those activities.

FAQ
Frequently Asked Questions
Key questions from foreign investors and business owners about the FBL process in Thailand.
Who needs a Foreign Business License in Thailand?+
Any company with more than 49% foreign shareholding that wishes to engage in a business activity classified under List 2 or List 3 of the Foreign Business Act requires an FBL prior to commencing operations in that activity.
How long does the FBL application process take?+
For List 3 activities, the DBD typically processes applications within 60 business days from the date of acceptance of a complete application. List 2 applications require Cabinet approval and generally take longer. Timelines vary depending on the completeness of the documentation and the nature of the business activity.
What is the minimum capital requirement for an FBL?+
The minimum registered capital for a foreign business seeking an FBL is generally THB 2 million per activity. However, some activities require higher minimums. The capital must be fully paid-up before or at the time of application, depending on the activity and structure.
Can a BOI-promoted company avoid the FBL requirement?+
Yes. BOI-promoted companies receive the right to operate with majority or full foreign ownership in their approved business activities, effectively substituting for an FBL. BOI promotion is often a faster and more commercially advantageous path for eligible activities and investment sizes.
What happens if a foreign company operates without an FBL?+
Operating a restricted business activity without the required FBL is a criminal offense under the Foreign Business Act. Penalties include fines of up to THB 1 million, imprisonment of up to 3 years, and the possibility of a forced business closure by Thai authorities.
Does a Treaty of Amity certificate replace the FBL?+
Yes. A valid Treaty of Amity certificate allows a US-majority company to operate in most business sectors in Thailand with full foreign ownership, without requiring a separate FBL. However, certain activities such as communications, transportation and natural resource exploitation remain restricted even under the Treaty.
Can B-Accounting assist with existing FBL amendments?+
Yes. If your business activities change or expand beyond the scope of your existing license, we can prepare and submit an FBL amendment application to the DBD. We also assist with registered capital increases and changes in license conditions.
