FAQ: Can a Foreigner Own 100% of a Thai Company in Udon Thani?

The short version: what 100% ownership really means under Thai law

Thailand allows 100% foreign ownership only when the activity is not restricted, or when the foreign investor secures the correct regulatory permission.

In Thai law, a company is considered “foreign” when foreign persons or foreign-controlled entities hold 50% or more of the shares (or control in practice). The Foreign Business Act (FBA) then becomes the main gatekeeper. Some categories of business are closed to foreigners. Others are conditionally open—license or promotion required. And a slice remains open without special permissions.

Udon Thani doesn’t rewrite the statute. It does, however, make logistics and stakeholder coordination more local—company registration with the Department of Business Development (DBD), visas and work permits via designated channels, and practical coordination with banks and accountants. Your structure should be chosen for what you do, not just where you set up.

Caution: Requirements can vary with your activity, document completeness, translations, and specific registrar or district office practices. Timelines and document lists are not one-size-fits-all.

Three lawful paths to 100% foreign control

You get full foreign ownership by staying outside restricted lists, or by obtaining BOI promotion, or by securing a Foreign Business License (or a treaty-based exemption).

There are only a few clean ways to reach 100% foreign shareholding without legal headaches:

• Operate outside restricted lists. Some activities are not restricted by the FBA. Certain types of manufacturing and export-oriented operations often fall here. If your activity is genuinely unrestricted, you can typically own 100% once you register the company correctly. Verification is key—category mapping is not guesswork.
• Board of Investment (BOI) promotion. If your project fits BOI policies (for example, targeted manufacturing, tech, R&D, or regional service centers), BOI may grant promotion that permits full foreign ownership for the promoted activity, along with tax and non-tax incentives. See the BOI’s official introduction and criteria: BOI Intro (PDF).
• Foreign Business License (FBL) or treaty route. For restricted activities you can apply for an FBL (issued under the FBA). In specific cases, treaty-based exemptions may apply (for example, a limited range of activities for certain treaty nationals). The analysis is technical and fact-sensitive.

One more truth worth stating plainly: using Thai “nominees” to disguise foreign control is illegal. The Ministry of Commerce scrutinizes suspicious structures. If the Thai shareholders are not genuinely capitalized or independently directing their stake, you are courting an enforcement problem—not a business strategy.

Activities often restricted for foreigners (and why it matters in Udon Thani)

Many service businesses—consulting, retail and wholesale trading, certain construction and service lines—are commonly restricted without BOI or an FBL.

Thailand’s FBA organizes restricted businesses into lists. The exact scope is technical, so do not rely on headlines like “services are banned.” Some services are restricted; some are not; many can be re-framed by BOI or structured properly. But here’s what trips investors up in practice:

• Service catch-all. A wide array of services (including many forms of consulting, internal management services, and technical support) can be restricted unless BOI-prompted or licensed. This is where many foreign SMEs accidentally cross the line.
• Trading & distribution models. Retail and wholesale can sit in restricted categories unless licensed or structured under a permissible model. There are lawful paths, but they must be engineered, not improvised.
• Project-based work. Construction or project services can be permission-sensitive and may require a combination of licensing and local qualifications. The specifics depend on the contract, counterparties, and whether BOI-backed.

Setting up in Udon Thani? The same categories apply. The difference is operational: vendor relationships, staffing, and provincial registrar coordination. That’s where local counsel earns its keep.

BOI vs Thai-majority vs foreign business license: how do you choose?

Match ownership to activity. BOI enables 100% where promoted; Thai-majority is common for restricted services without BOI; FBL works when you can justify the license for a specific restricted activity.

Different routes solve different problems. Don’t force-fit your plan into the wrong container.

Checklist: can you own 100%? A quick decision flow

Map your activity, validate restrictions, then choose the lawful path that fits.

Use this sequence before you register anything:

1. Define the real activity. Plain language. What will the company do daily in Thailand—deliverables, clients, revenue lines?
2. Map the activity against FBA lists. Identify whether it’s restricted, unrestricted, or potentially BOI-eligible. When unclear, assume restricted until confirmed.
3. If unrestricted: Proceed with standard company registration and 100% foreign shareholding, subject to capital and other general requirements.
4. If potentially BOI-eligible: Build a BOI case (project plan, technology/use-of-Thai-resources, benefits). If promoted, implement within BOI scope.
5. If restricted and not BOI-eligible: Prepare a Foreign Business License application for the specific activity, or consider a Thai-majority company where the Thai shareholders are real investors with real rights.
6. Sanity check governance. Shareholder agreements, director authority, reserved matters. Compliance first, then control mechanisms within the lawful structure.
7. Paperwork reality check. Foreign-issued documents may require legalization or translation. District office practices vary; build time for document readiness.

Local caution: Registration steps at the DBD are administrative; they do not override foreign-business restrictions. Getting a company number is not the same as getting permission to engage in a restricted service.

Company registration vs foreign-business permission: don’t confuse them

DBD registration creates the entity; BOI or FBL grants permission for restricted business. These are separate tracks.

Two parallel tracks often get mixed up:

• Company registration (DBD). Incorporates the entity, records shareholders and directors, and issues corporate documents. See the DBD’s process outline: DBD Company Registration Guide.
• Foreign-business permission (FBA regime). If your activity is restricted, you need either BOI promotion or a Foreign Business License. The DBD publishes data and analysis on FBA matters; the Ministry of Commerce oversees licensing. See: DBD FBA Annual Report 2024.

These tracks interact but never merge. You must secure both the right entity and the right permission—in that order, with evidence to match. If you’re offered a shortcut, pause.

Visas, work permits, and day‑to‑day operation in Udon Thani

Corporate ownership and immigration are separate but connected—plan both. BOI can streamline some immigration steps.

Even with 100% ownership, you still need proper visas and work permits if foreign directors or staff will work in Thailand. The One Start One Stop Investment Center provides official guidance on immigration processes for investors: OSOS Visa & Work Permit Guidance.

Expect that immigration and labor compliance turn on facts: job roles, corporate capital, office arrangements, and support documents. Numbers and thresholds change over time. Build flexibility into your plan and verify current requirements before you hire.

Anti‑nominee reality check. If your structure relies on Thai nominees or back‑to‑back funding to disguise control, you are inviting regulatory trouble. Thai officials are trained to test substance—board control, funding sources, decision-making, and actual business activity. Keep your structure lawful and defensible on paper and in practice.
