Can Foreigners Own 100% of a Thai Company? Every Route Explained

Ask ten expats in a Bangkok co-working space whether a foreigner can own a Thai company outright and you will get ten confident answers, most of them wrong. The famous "49 percent rule" gets quoted like gospel, usually by someone who read it on a forum in 2015. The truth is more interesting and, for anyone building a real business here, far more useful.

So, can foreigners own a company in Thailand? Yes, right up to 100 percent. You just cannot do it by default. Full ownership is a door you unlock through one of a few specific routes and picking the right one depends on your nationality, your industry and how much time and capital you are willing to commit. Here is every legal path, explained in plain English.

The 49 percent default

The rulebook here is the Foreign Business Act B.E. 2542, better known as the FBA, passed in 1999 and still the law of the land. It defines a company as "foreign" the moment non-Thais hold 50 percent or more of the shares. Cross that line and you fall under a thicket of restrictions and licensing requirements. Stay at 49 percent or below and, in the eyes of the law, you are running a Thai company. That single percentage point is where the whole "49 percent rule" comes from.

The FBA sorts restricted activities into three lists. List 1 covers businesses closed to foreigners entirely, such as land trading, farming and most media. List 2 covers sectors tied to national security or culture and needs Cabinet-level approval. List 3 is the big one for most founders: services, consulting, retail and a long tail of activities where Thailand has decided local firms are not yet ready to compete. If your business lives on List 3 and you want more than 49 percent, you need a license or an exemption.

Then 2026 arrived and moved the goalposts. On 1 April 2026, the Department of Business Development brought in DBD Order No. 1/2569, which tells registrars to stop taking share registers at face value. They now look at who actually controls the company: who funded it, who runs the board and who makes the real decisions. Thai shareholders in any company with foreign participation must show genuine source-of-funds documentation proving they paid for their own shares. A related order effective 1 January 2026 requires the same financial proof on new registrations and from that date every private limited company must register through the DBD's online platform rather than in person. The takeaway: the 49 percent structure still works, but only if your Thai partners are real partners with real money in the deal.

The BOI route: full ownership plus a tax holiday

The Board of Investment, or BOI, is Thailand's investment promotion agency and its favorite tool for attracting the industries it wants. If your business fits one of its promoted categories, BOI company registration is often the best deal on the table.

Get approved and you can own 100 percent of your company, no Thai partner required. You also collect a serious package of perks: corporate income tax exemptions of up to 13 years, import duty relief on machinery and a streamlined process for foreign work permits and visas that skips the usual staffing ratios. BOI-promoted companies receive a Foreign Business Certificate rather than sweating through a full license application, which cuts weeks of paperwork.

The catch is eligibility. BOI wants industries that add value to the Thai economy: advanced manufacturing, digital infrastructure, technology, R&D and life sciences. A corner cafe or a general trading shop will not qualify. Capital requirements also run higher, often from THB 10 million upward depending on the activity and applications are reviewed against real criteria rather than rubber-stamped. But for the businesses BOI is courting, nothing else comes close.

The Foreign Business License route

If BOI does not fit and you are not American (more on that shortly), the Foreign Business License, or FBL, is the general-purpose key to List 2 and List 3 activities. In theory it can grant up to 100 percent foreign ownership in a restricted sector. In practice it is the slow lane.

To apply you generally need minimum registered capital of THB 3 million per restricted activity. The DBD then weighs your application on economic necessity, technology transfer and how many Thais you will employ. There is no guaranteed outcome, the review is document-heavy and decisions can take a couple of months. Approval is a judgment call, not a formality, which is exactly why founders who qualify for BOI or the Treaty of Amity usually reach for those instead. The FBL is the route you take when the other doors are closed.

The US Treaty of Amity

American investors get their own express lane. The US-Thailand Treaty of Amity and Economic Relations, signed in 1966 and still fully in force in 2026, lets US citizens and US-owned companies hold up to 100 percent of a Thai business in most sectors, with the same national treatment a Thai company enjoys. No FBL required.

There are conditions. US nationals must hold the majority of shares, the majority of directors must be American or Thai and that American ownership has to hold all the way up the chain to the ultimate parent company. Spinning up a shell company in Delaware and calling it American will not work: the treaty tests real US ownership and control. A qualifying company applies for a Foreign Business Certificate through the DBD for a modest fee.

The treaty also has hard limits, often called the "Big Six" exceptions. It does not cover communications, transportation, fiduciary and banking functions, land trade or ownership, exploitation of natural resources or domestic trade in Thai agricultural products. Land ownership in particular stays firmly off-limits. If your business touches one of those, you are back to BOI or an FBL. For everyone else, the Treaty of Amity is the fastest and most reliable path to full American ownership.

Nominee structures and why to avoid them

Here is the route you will hear whispered about and should ignore. A nominee structure is where a Thai person or company holds 51 percent of your shares on paper while you keep real control behind the scenes. It looks like a tidy workaround. It is a criminal offense.

Under Sections 36 and 37 of the FBA, both the foreigner and the Thai nominee can face up to three years in prison and fines from THB 100,000 to 1 million and courts can order the company dissolved on top of that. This is not a dusty rule nobody enforces. The 2026 reforms were built specifically to hunt nominee arrangements down, cross-referencing banking data, director changes and beneficial-ownership records to spot Thai "shareholders" who never actually paid for their shares. Regulators have made it clear that substance now beats paperwork. A structure that looked fine in 2020 can unravel fast in the current climate. The legitimate routes above exist precisely so you never have to gamble your business and your liberty on a nominee.

Here is the quick comparison. Match your nationality and industry to the row that fits, then pressure-test it against your capital and timeline.

Frequently asked questions

Can foreigners own a company in Thailand? Yes. Foreigners can own up to 49 percent of a company in a restricted sector with no license at all and up to 100 percent through BOI promotion, a Foreign Business License or the US Treaty of Amity. The right route depends on your industry and nationality.

Do I always need a Thai partner? No. You only need genuine Thai shareholders if you take the Thai-majority route and stay at or below 49 percent. BOI promotion, an FBL and the Treaty of Amity all allow full foreign ownership with no Thai partner required.

Can a foreigner be a director of a Thai company? Yes. Directorship is separate from ownership, so a foreigner can be a director even in a Thai-majority company. Bear in mind that any foreigner working in Thailand, director or not, needs a valid work permit.

Is the 49 percent rule going away? Not yet. Thailand has floated liberalizing reforms and delisted a handful of sectors, but the core 49 percent default still stands in 2026. If anything, enforcement of the control rules got stricter this year, not looser.

What if my business is not on any FBA list? Some activities, notably much of manufacturing, sit outside the FBA's restricted lists entirely. In those cases a foreigner can often own 100 percent with no special license. It is always worth confirming exactly how your activity is classified before you assume you need a license.

The bottom line

Owning a Thai company as a foreigner is not the closed door the rumor mill makes it out to be. It is a routing problem. Match your nationality and your industry to the right structure and full ownership is well within reach. The harder part is often what comes next: the visas and work permits that let you and your team actually run the thing.

That is where planning ahead pays off. Settlr Global, a Wows Global company, handles the full stack from incorporation to work permits in one place, so you can lock in the right ownership route and keep moving.
