How to Register a Company in Thailand as a Foreigner
Learn how to register a company in Thailand as a foreigner: the process, foreign ownership rules, typical costs and timeline, and mistakes to avoid.
Registering a company in Thailand as a foreigner means incorporating a Thai Limited Company through the Department of Business Development (DBD), the same core process Thai nationals use - while working within the ownership limits set out in the Foreign Business Act (FBA). For most straightforward businesses, incorporation itself takes a matter of weeks. The bigger question isn't how fast you can register a company in Thailand as a foreigner, it's how much of it you'll actually be allowed to own, which depends entirely on what your business does.
This guide walks through the process at a high level: what to expect, which company structure fits your situation, where foreign ownership rules apply, what it typically costs, and the mistakes that trip up first-time founders. It isn't a substitute for a proper consultation - every business's situation is different - but it should give you a clear, honest picture before you start.
Thailand remains one of the more accessible markets in Southeast Asia to set up in, with a well-established process, a large community of foreign-owned businesses already operating, and a government agency (the DBD) that's used to handling foreign applicants. That accessibility can be misleading, though - the paperwork to register a company in Thailand as a foreigner is genuinely straightforward, but the ownership decisions layered on top of it are where most of the real complexity lives.
Two Paths, One Process
Whether you're a solo entrepreneur setting up on your own or a foreign company opening a Thai subsidiary, the mechanics of registering a company in Thailand as a foreigner are largely the same: reserve a name, file incorporation documents, register with the DBD, and open a bank account. What tends to differ is scale and structure.
A solo founder registering a company in Thailand usually incorporates a smaller Thai Limited Company, often with local shareholders brought in to meet ownership requirements for the business activity involved. A foreign company opening a subsidiary typically brings in more capital, may pursue BOI promotion to retain full ownership, and has to think from day one about how the Thai entity reports back to the parent company - which is where consistent bookkeeping and translated financial statements start to matter early on, not as an afterthought once the business is already running.
Either way, the ownership structure is the decision that shapes everything else: capital requirements, how long the process takes, and what kind of control you'll have. So it's worth understanding before you touch the paperwork.
Choosing a Business Structure
Before registering a company in Thailand, foreign founders typically choose between a few structures:
Private Limited Company - by far the most common choice. It offers limited liability, can engage in a full range of business activities (subject to the FBA), and is the structure most banks, partners, and government agencies expect to see.
Branch Office - an extension of an existing foreign company, allowed to generate revenue in Thailand, but still subject to the same foreign ownership restrictions as a locally incorporated entity.
Representative Office - suited to non-revenue-generating activities like market research, quality control, or liaison work. It's simpler to set up but can't conduct commercial transactions.
For nearly all foreign entrepreneurs and most subsidiaries, the Private Limited Company is the structure that makes sense, which is why the rest of this guide focuses on it. It's also the structure that lets you register a company in Thailand once and grow into it - adding shareholders, applying for BOI promotion later, or hiring staff - rather than needing to re-incorporate as the business scales.
The Registration Process at a Glance
Reserve your company name with the DBD (both a Thai and an English version). Approval typically takes a few business days, and the reserved name is valid for 30 days. You need to complete the next steps within that window or start over.
Prepare the Memorandum of Association (MOA), which sets out the company name, registered address, business objectives, share capital, and details of the promoters.
Hold the statutory meeting, where shareholders formally adopt the company's regulations, appoint directors, and approve the share structure.
Submit everything to the DBD for registration. Once documents are complete and signed, this step is often the fastest part of the process.
Register for a Tax ID, and for VAT if your business will exceed the revenue threshold or otherwise needs to register.
Open a corporate bank account, usually the step that takes longest to schedule, since banks have their own documentation and in-person requirements.
As of 2026, company registration in Thailand is filed through the DBD's online platform rather than in person, which has shortened processing times compared to a few years ago.
None of these steps is difficult on its own - where foreign founders usually lose time is in the documentation: certified translations, notarized signatures for anyone signing from overseas, and making sure the business objectives listed in the MOA actually match what the company will do day to day. Getting that wrong doesn't stop registration, but it causes problems later when the described activity doesn't match reality on tax filings or license applications.
Foreign Ownership Rules: What You Can (and Can't) Own Outright
This is the part most first-time founders underestimate. The Foreign Business Act divides business activities into categories, and where your business falls determines your ownership options when registering a company in Thailand as a foreigner:
Some activities are closed to foreign ownership entirely, including a narrow list of businesses tied to national interests, such as media, land trading, and similar sectors.
Many service-based businesses fall into a restricted category, where foreign ownership above a set threshold requires a Foreign Business License (FBL) from the DBD. The process takes real time and isn't guaranteed.
Businesses that don't fall under any restricted category are generally open to full foreign ownership without special approval.
For restricted activities, there are three established, legal ways to reach majority or full foreign ownership:
A Foreign Business License (FBL), applied for directly, which involves demonstrating the business will benefit Thailand's economy.
Board of Investment (BOI) promotion, available for businesses in categories Thailand wants to attract - this can grant 100% foreign ownership plus tax incentives, but the application and approval process takes several months.
The US–Thailand Treaty of Amity, available only to US citizens and majority-US-owned companies, which allows near-full ownership rights outside a small set of restricted sectors.
One thing worth being direct about: using a Thai "nominee" shareholder, someone who holds shares on paper but has no real stake in the company, to get around these rules is illegal under the FBA, and enforcement has tightened noticeably in recent years. Authorities can and do investigate shareholding structures after the fact, which means a nominee arrangement that "works" at registration can still unravel later. It's not a shortcut worth taking, however common it may seem in tourist-heavy areas.
Typical Costs and Timeline
Costs and timelines vary a lot depending on business activity, ownership structure, and how quickly documents come together. So treat the following as a general sense of scale rather than a quote:
Standard incorporation (no FBL or BOI involved) commonly takes a few weeks from name reservation to receiving your certificate of incorporation, assuming documents are complete and signed promptly.
BOI promotion, if you're pursuing it, adds several months on top of incorporation.
An FBL application typically adds even more time, since approval isn't guaranteed and depends on demonstrating clear benefit to Thailand.
Minimum capital requirements differ depending on your structure - foreign-majority companies and those sponsoring foreign work permits face higher thresholds than Thai-majority companies.
Ongoing costs to plan for beyond registration itself include accounting and bookkeeping, the annual statutory audit every Thai company is required to file, and if relevant, work permit renewals for foreign staff.
None of these figures are one-size-fits-all, which is exactly why so many foreign founders get a rough number from a forum post, budget around it, and then find out midway through the process that their specific business activity, capital source, or work permit needs put them in a different bracket entirely. This is exactly the kind of detail worth getting confirmed for your specific situation before you commit to a structure. A quick consultation before you register a company in Thailand is far cheaper than restructuring later once capital has already been committed and documents have already been filed.
Common Mistakes Foreign Founders Make
Assuming 100% ownership is automatic. It depends entirely on your business activity. Check this before you get attached to a structure.
Using a nominee shareholder arrangement. It's illegal, increasingly scrutinized, and puts both the foreign founder and the Thai "shareholder" at risk.
Letting the 30-day name reservation window lapse because documents weren't ready - plan the paperwork before you reserve the name, not after.
Underestimating what a work permit requires. Sponsoring a foreign employee (including yourself, if you'll be working in the business) comes with its own capital and documentation requirements separate from incorporation itself.
Treating BOI or FBL timelines as an afterthought. If full foreign ownership matters to you, build the extra months into your plan from day one rather than discovering the delay midway through.
Registering the company before lining up the right support. Thai companies have bookkeeping, tax filing, and audit obligations starting almost immediately. Waiting until the first deadline is looming is the most common reason first-year filings go wrong.
Frequently Asked Questions
Can a foreigner own 100% of a company in Thailand? Yes, in some cases. If the business activity isn't restricted under the Foreign Business Act, or if you obtain BOI promotion, an FBL, or (for US nationals) Treaty of Amity protection. For many restricted service businesses, full ownership isn't automatic and needs one of these routes.
How long does it take to register a company in Thailand as a foreigner? Straightforward incorporation is often a matter of weeks. If you're also pursuing BOI promotion or a Foreign Business License, add several months for those approvals on top of incorporation itself.
Do I need a Thai partner to register a company in Thailand? Not always. It depends on your business activity and how you want to structure ownership. Many foreign founders do bring in Thai shareholders to simplify the process, but genuine full foreign ownership is possible through the routes above.
What's the difference between BOI promotion and a Foreign Business License? BOI promotion is aimed at businesses in categories Thailand wants to attract, and can include tax incentives alongside full ownership. An FBL is a more general application route open to a broader range of restricted activities, evaluated case by case.
Can a foreigner be the sole director of a Thai company? Generally yes. Thai law doesn't restrict the nationality of company directors. Ownership rules and director rules are separate questions, so a foreign-owned company can still have entirely foreign leadership even where shareholding is constrained.
What happens after I register a company in Thailand? Registration is the starting line, not the finish. You'll need to register for tax, set up bookkeeping, meet annual audit and filing deadlines, and if you're hiring - handle payroll and social security registration for employees.
