What the Foreign Business Act actually says, the three Lists of regulated activities, and the four legal ways to operate a foreign-majority company in Thailand.
The Foreign Business Act B.E. 2542 (1999) is the Thai law that controls what business activities a foreign-majority company can do in Thailand. "Foreign" under the FBA is broad. It includes companies registered outside Thailand and any Thai-registered company where foreigners hold 50% or more of the shares, or where foreigners hold half or more of the voting rights.
If a company falls on the foreign side of that line, its business activity has to either sit outside the FBA's regulated lists, or qualify for one of the explicit exemptions. There's no informal workaround.
The FBA divides regulated activities into three Lists. List 1 is closed to foreigners entirely. It covers newspapers, broadcasting, rice farming, livestock, forestry, fisheries inside Thai waters, Thai herb extraction, trading in Thai antiques, and Buddhist images, among other items.
List 2 covers activities involving national security, art and culture, or natural resources. A foreign-majority company can operate in List 2 only with Cabinet approval, which is rare in practice.
List 3 is the long one and the one most foreign founders run into. It covers most services, retail under a certain capital floor, wholesale, construction, brokerage, advertising, hotels (excluding hotel management), and many professional services. It's closed to foreign-majority ownership unless the company qualifies for an exemption.
The shorthand most foreign founders hear is "you need 51% Thai ownership". That comes from List 3. To operate a List 3 business without an exemption, foreigners can hold at most 49% of the shares and at most half of the voting rights. The Thai 51% has to be substantive: the shares have to be genuinely held by Thai persons or Thai-majority entities, and the law looks at voting rights and de-facto control, not just the share register.
Many activities that look like ordinary commerce (running a restaurant, a shop, an agency, a consulting firm, a logistics broker, a marketing agency) are List 3. That's why the 49% rule comes up so often, and why it's worth checking the activity classification before you settle on a corporate structure.
There are four practical ways for a foreign-majority company to operate List 3 activities legally. BOI promotion lifts the foreign-ownership cap for the specific promoted activity. The US-Thai Treaty of Amity lets companies majority-owned by US persons operate most List 3 activities at 100% foreign ownership, with a short exclusion list.
A Foreign Business Licence (FBL) is a discretionary licence from the Ministry of Commerce, reviewed case by case by the Foreign Business Committee. It is slow, the criteria are not fully published, and approval is not guaranteed. Free-trade-agreement pathways such as TAFTA (Australia) and JTEPA (Japan) carve out specific activities for nationals of those countries, with their own paperwork.
None of these are automatic. Each one has its own application process, its own ongoing reporting, and its own list of activities it covers. Checking which exemption applies to your specific activity is the first practical step.
Using Thai "nominee" shareholders to satisfy the 51% Thai-ownership rule on paper, while the foreign founder actually controls the company, is illegal under FBA Section 36. The legal exposure is real: the company can be ordered to dissolve, the foreign principal and the Thai nominee can both face fines and imprisonment, and the Department of Business Development has stepped up scrutiny of suspicious shareholder structures over the last two years.
If a business genuinely can't qualify for an exemption, the right answer is usually to restructure (different activity classification, BOI promotion, smaller foreign stake with real Thai partners, or a different vehicle) rather than dress up a 49/51 split that isn't real.
