Introduction
Foreign founders and international companies are often surprised by how “two-speed” Thailand can feel from an ownership perspective:
- In some industries, 100% foreign ownership is realistic and common.
- In others — especially service-heavy or locally protected sectors — foreign ownership can trigger Foreign Business Act (FBA) restrictions, licensing requirements, capital thresholds, and ongoing compliance constraints.
That gap matters because “foreign ownership” in Thailand is not just about what percentage of shares you hold. It affects:
- whether your company is legally considered a “foreigner,”
- whether you can carry out certain business activities without permission,
- whether you must obtain a Foreign Business License (FBL) (or an alternative approval route),
- and what your capital and director composition may need to look like.
This article gives you a practical, business-first guide to foreign ownership in Thailand in 2026:
- the FBA basics (in plain English),
- what you can and can’t do,
- and compliant workarounds that companies commonly use — without drifting into risky “nominee” territory.
Important Note:
This article is general information, not legal advice. Thailand’s rules are activity-specific and enforcement can be very fact-dependent. Always validate your exact business scope before you commit to a structure.
1. The Foreign Business Act (FBA)
What the FBA is trying to do?
Thailand’s Foreign Business Act is the main framework that restricts certain activities for “foreigners.”
It divides restricted activities into three lists and sets different approval standards for each list.
Who counts as a “foreigner” under the FBA?
The FBA definition is broader than many people expect. Under the Act, a “foreigner” includes:
- non-Thai individuals,
- companies not registered in Thailand,
- and Thailand-registered companies where at least one half of the capital shares are held by foreigners (or equivalent foreign investment thresholds).
Practical Takeaway:
If your Thailand company is 50%+ foreign-owned, it will generally be treated as a “foreigner” under the FBA — meaning restricted activities can require permission.
2. The Three Lists: What You Can & Can’t Do
The FBA uses three lists with escalating permission requirements. The key section describes the “no foreigner may operate…” rules clearly:
List 1: Completely prohibited for foreigners
List 1 activities are not permissible for foreigners (“stricto sensu not permissible”).
What this Means:
If your intended business is clearly List 1, you typically need to change scope, change structure, or consider an alternative market approach — because a standard foreign-owned setup won’t solve it.
List 2: Allowed only with Minister + Cabinet approval
List 2 covers activities tied to national safety / security, culture / tradition, environment / natural resources impacts. Foreign operation requires permission from the Minister with approval of the Council of Ministers.
The Act also states specific governance/shareholding expectations for List 2:
- a foreign juristic person may operate List 2 only where not less than 40% of shares are held by Thai nationals (with limited ability to reduce to not less than 25% with approval), and
- not less than two-fifths of directors must be Thai nationals.
What this Means:
List 2 is typically the hardest category to access as a foreign investor unless you have a highly strategic case.
List 3: Allowed with a Foreign Business License (FBL)
List 3 is the “most common pain point” for foreign entrepreneurs because it often includes service categories where “Thai nationals are not yet ready to compete with foreigners.”
For List 3, foreigners can operate only if they obtain permission from the Director-General with approval of the relevant commission (as set out in the Act).
What this Means:
Many normal “modern business” activities (especially service-heavy models) can fall into List 3, and this is where planning and structuring matter most.
3. Capital & Timeline: The Hidden Cost Drivers
Even before you talk about strategy, the FBA itself sets minimum capital expectations:
- minimum capital for a foreigner commencing business in Thailand must not be less than 2,000,000 THB, and
- if the business requires permission under the restricted lists, the minimum capital shall not be less than 3,000,000 THB per business (as prescribed in ministerial regulations).
On timing, the Act describes a review window for permission decisions:
- consideration within 60 days from filing (with potential extension in some cases), and issuance steps thereafter.
Practical Takeaway:
Foreign ownership planning is not just a shareholding question — capital planning and regulatory timelines can become the real bottleneck.
4. The Big Compliance Trap: “Nominee” Shareholders
A common misconception is: “I’ll keep foreigners at 49% and everything is fine.”
Thailand does allow Thai-majority companies for many contexts, but Thai shareholders must be genuine investors, not stand-ins. Authorities scrutinize illegal nominee arrangements, and using “proxy Thai shareholders” can create serious legal and operational risk.
At the same time, it’s also true that Thai-majority companies can use corporate governance mechanisms to protect foreign investors — if done carefully and lawfully. A practical overview of legitimate control mechanisms (e.g., reserved matters, board composition, share classes) is commonly discussed as a compliant pathway, with the caveat to avoid anti-nominee violations.
Bottom Line:
If you want Thai majority, you need real Thai partners with real economic participation — and your governance structure should be designed transparently.
5. Lawful “Workarounds” That Foreign Investors Actually Use
When people say “workaround” in Thailand, they sometimes mean “ways to bypass.” That’s not the game you want to play.
Here are the compliant options that real companies use to align foreign ownership goals with Thailand’s rules.
Workaround #1: Apply for a Foreign Business License (FBL)
If your company is a “foreigner” under the Act and your activities fall under List 3 (and sometimes List 2), the formal path is to apply for permission under the FBA framework.
Why companies choose this?
– You can keep majority foreign ownership (when approved).
– You avoid fragile nominee structures.
– It creates a clean compliance foundation for banking, contracts, and future due diligence.
What improves approval odds?
While each case differs, regulators generally want to see a legitimate contribution case (e.g., technology, jobs, investment, capability transfer) and a properly documented business plan (this is widely discussed by professional advisory sources).
Watch-outs
– licensing is discretionary,
– timelines can be meaningful,
– and you still need to respect minimum capital requirements under the Act.
Workaround #2: BOI Promotion (Investment Promotion Route)
For eligible activities, BOI promotion can be a powerful route because it can change what you’re allowed to do with foreign ownership — especially in promoted industries.
The FBA itself recognizes that when a foreigner is promoted under Thailand’s investment promotion law and their activity falls within List 2 or List 3, they can notify the Director-General to obtain a certificate (instead of going through the standard permission route).
Why this Matters
– It signals a legal pathway where investment-promotion status interacts with FBA restrictions.
– Practically, BOI promotion is often discussed as enabling higher foreign ownership and faster work permit/visa facilitation for eligible business activities (especially in priority sectors).
The Real-World Constraint
BOI is not a “free pass.” Your business must match an eligible promoted activity, and you must operate within the approved scope. Anything outside the promoted scope can re-trigger FBA issues (a common operational pitfall).
Workaround #3: Treaty of Amity (U.S. Nationals / U.S.-Owned Companies)
If you are a U.S. citizen or a qualifying U.S.-owned entity, the U.S. – Thailand Treaty of Amity and Economic Relations is a major carve-out.
The treaty provides national treatment for establishing and acquiring interests in enterprises, but it explicitly reserves the right to restrict certain sectors — communications, transport, fiduciary functions, banking involving depository functions, exploitation of land / natural resources, and domestic trade in indigenous agricultural products.
Why companies choose it
- It can allow U.S.-owned companies to operate in Thailand with ownership rights closer to Thai companies for many activities, while respecting the treaty’s excluded sectors.
Watch-outs
- Treaty eligibility is nationality-specific and procedural.
- Excluded sectors still apply, and other Thai laws can still restrict certain activities.
Workaround #4: Representative Office
A Representative Office can be a legitimate way to establish a presence for non-revenue, support-only activities — especially in early market entry stages.
Credible summaries consistently note that a Representative Office:
- cannot generate revenue in Thailand,
- and should not engage in sales/purchase contracting and commercial transactions.
When it’s a good fit
- market research and partner development,
- quality control / supplier coordination,
- internal support activities for a foreign head office.
When it’s not a fit
- selling to customers in Thailand,
- signing commercial contracts locally,
- invoicing locally or collecting revenue locally.
If your plan includes real commercial operations, you typically consider upgrading to another structure (e.g., subsidiary/branch + appropriate permissions).
Workaround #5: Thai-Majority Joint Venture
This is the most common strategy in practice when:
- the activity is likely restricted under the FBA,
- the company doesn’t qualify for BOI or treaty routes,
- and the business can be successfully built with local partners.
A Thai-majority company (often 51% Thai / 49% foreign) can be a compliant structure — but only if Thai shareholders are real investors and the governance is not designed to simulate illegal nominee control.
How foreign investors protect their position?
Common governance protections include:
- reserved matters requiring supermajority approval,
- board composition agreements,
- share classes (where lawful and properly structured),
- shareholder agreements defining transfer restrictions and deadlock resolution.
The non-negotiable rule
Do this only with real alignment and clean documentation. If it smells like nominees, it becomes hard to bank, hard to sell, and risky to operate.
6. Decision Framework: Which Route Fits Your Business?
Use this simple sequence:
Step 1 — Define your exact “business activities”
Thailand is activity-based. Two companies in “tech” can be treated differently if one is pure software development and the other is delivering regulated services.
Step 2 — Determine if your planned ownership makes you a “foreigner”
If foreign shareholding reaches 50% or more, the company is generally a foreigner under the FBA.
Step 3 — Check which list your activities fall into
- If List 1 → plan for scope change or a different market strategy.
- If List 2 → expect the highest bar (Minister + Cabinet) and stricter composition expectations.
- If List 3 → plan for FBL or a lawful alternative route.
Step 4 — Choose your pathway
- BOI promotion if you fit eligible promoted activities and want a strategic setup.
- Treaty of Amity if you qualify and your activity isn’t excluded under the treaty.
- FBL if you need majority control and you can build a strong approval case.
- Thai JV if local partnership is strategically sensible and properly structured.
- Representative Office if your Thailand presence is support-only (no revenue).
7. Common Mistakes Foreign Investors Make
Mistake #1: Assuming “49% foreign” automatically means “no restrictions”
It can reduce FBA risk, but it does not eliminate sector rules, licensing needs, or compliance scrutiny — especially if business reality conflicts with paper ownership.
Mistake #2: Using nominee shareholders “for speed”
This is one of the highest-risk shortcuts and can cause major problems in banking, audits, disputes, and eventual sale.
Thai shareholders should be genuine investors.
Mistake #3: Mixing restricted and unrestricted activities in one entity
Even BOI-promoted companies can face FBA issues for activities outside the promoted scope.
This is why scope discipline and entity design matter.
Mistake #4: Undercapitalizing the structure
The FBA includes minimum capital concepts (including higher minimums for restricted businesses).
Even beyond legal thresholds, undercapitalization can cause practical issues with payroll, visas, and vendor relationships.
Mistake #5: Treating the Treaty of Amity as “covers everything”
It provides broad rights, but the treaty explicitly reserves restrictions for certain sectors.
Conclusion
Foreign ownership in Thailand is absolutely workable — if you match the right structure to the right activity.
The Foreign Business Act draws a clear line:
- If you’re treated as a “foreigner” (often 50%+ foreign ownership) and your activities sit in restricted lists, you may need permission.
- Some categories are effectively closed (List 1), others require heavy approvals (List 2), and many service activities require an FBL or a recognized alternative pathway (List 3).
The good news is that compliant options exist — FBL, BOI promotion, Treaty of Amity, Representative Office, and proper Thai joint ventures — each with different trade-offs in speed, control, and compliance burden.
