Company Registration in Thailand
Set up your Thai company on the right ownership route for your business. Foreign ownership is capped at 49% by default, but a BOI promotion, a Foreign Business Licence, or the US Treaty of Amity can take you to 100%. We plan the capital around your work permits and handle the DBD registration, the bank account, and compliance.
What to decide before anything is filed
In Thailand, the structure decisions outweigh the paperwork. The ones made before anything is filed decide whether the setup holds for years or unravels at the first audit.
Your ownership route
The Foreign Business Act treats a company as foreign once foreigners hold half the shares, and restricts foreign companies in most services. The route question comes before everything: Thai-majority structure, BOI promotion, a Foreign Business Licence, the US Treaty of Amity, or an unrestricted activity like manufacturing or export.
See the five ownership routes →BOI promotion, or not
Board of Investment promotion grants 100% foreign ownership, corporate tax holidays, land rights, and streamlined work permits for qualifying activities. It adds two to four months upfront and ongoing reporting. For eligible tech, manufacturing, and regional-hub businesses, it is usually worth both.
When BOI is worth it →Capital and the work permit math
There is no meaningful general minimum, but THB 2 million in paid-up capital per foreign work permit, staffing ratios, and THB 3 million for licensed activities set the real number. The capital follows your relocation and hiring plans rather than the legal minimum.
How the capital math works →Where control lives
In a Thai-majority structure, the foreigner holds a minority of shares. So control has to be designed lawfully, through signing authority, the articles, share classes, and shareholder agreements. The Thai partners must be real, with documented funds. Nominee arrangements are illegal and actively prosecuted.

Schedule a callKey requirements when setting up a company in Thailand
What the law requires of a Thai private limited company. If you can tick these six, you can incorporate.
- At least two shareholders. Reduced from three in February 2023, so older guides overstate it. Individuals or corporate entities; whether foreigners hold less than half decides the company's status under the Foreign Business Act.
- At least one director. Any nationality, with no residency requirement. The registered signing authority decides who can bind the company, which is where control actually lives.
- A registered address in Thailand. Residential or commercial, with the owner's consent documents. VAT registration and work permits hold the address to a higher standard than the incorporation itself.
- Capital planned to purpose. Shares of at least THB 5, with 25% paid up at registration. The real thresholds: THB 2 million paid-up per foreign work permit, THB 3 million for activities run under a Foreign Business Licence.
- A permitted activity, or a route. Foreign-majority companies need their activity outside the FBA's restricted lists, or BOI promotion, a Foreign Business Licence, or Treaty of Amity status.
- A reserved company name. Filed with the DBD in Thai script (an English version can accompany it), up to three choices, approved in one to three days and held for 30 days.
Steps to register a company in Thailand
Below are the steps to set up a company in Thailand as a foreign investor, in the order they happen. For each one you will find what to prepare, what it costs, how long it takes, and the mistakes we see most often, so you can plan the whole project before you start it.
Choose your ownership route
Thailand's defining rule sits in the Foreign Business Act: a company where foreigners hold half or more of the shares is "foreign," and foreign companies are restricted in most service businesses. Everything else in the setup follows from how you answer this, so the route comes first.
- Thai-majority company: foreigners hold up to 49.99%, the company is Thai under the FBA, and no license is needed. Control is designed lawfully through the structure (step 2).
- BOI promotion: qualifying activities get 100% foreign ownership, tax holidays, land rights, and streamlined work permits, at the cost of a two-to-four-month application and ongoing reporting.
- Foreign Business Licence: case-by-case permission to run a restricted activity with foreign majority. Discretionary, three to six months, and approval is not guaranteed.
- Treaty of Amity: US-majority companies can operate most activities as if Thai, one of the strongest routes where the shareholders qualify.
- Unrestricted activities: manufacturing for sale and export are largely outside the FBA's lists, so 100% foreign ownership works without any license.
The lists themselves are moving: Thailand has been progressively delisting service categories from the license requirement through 2025 and 2026, with further Cabinet-approved amendments in progress. Whether your exact activity is restricted today is a question we answer against the current lists, not last year's guides.
Structure the shareholding, control, and capital
A Thai limited company needs at least two shareholders (reduced from three in 2023) and at least one director of any nationality. In a Thai-majority structure, the design question is where control lives when the foreigner holds a minority of shares. It comes down to who has signing authority, what the articles allow, and how share classes and shareholder agreements distribute decisions. Done lawfully, with real Thai partners whose participation and funds are genuine, these structures hold. The DBD requires Thai shareholders to document their source of funds whenever a foreigner sits as director or shareholder, and structures built to disguise foreign ownership fail exactly that test.
Capital is planned to purpose. Shares carry a minimum value of THB 5 with at least 25% paid up at registration, and there is no meaningful general minimum. The real numbers come from your plans: THB 2 million in paid-up capital for each foreign work permit the company will sponsor, THB 3 million where the company operates under a Foreign Business Licence, and a registered capital above THB 5 million triggers bank evidence that the directors received the funds.
Reserve the name and register through DBD Biz Regist
Since January 2026, company registration runs exclusively through the DBD's Biz Regist platform; the paper filings and walk-in counters are gone. The name is reserved first, filed in Thai script with up to three choices, approved in one to three days and held for 30 days. The name must end in "Limited" and clear the DBD's similarity and restricted-word rules.
The registration bundle follows: the Memorandum of Association setting out the objectives, capital, and promoters, the statutory meeting that adopts the articles and appoints directors and the auditor, and the registration application itself, around THB 5,500 in government fees. Foreign documents must be translated by certified translators, and Thai shareholders' source-of-funds evidence goes in the file where a foreigner is involved. Approval typically lands within a week, and the company certificate arrives together with its tax ID.
Register for VAT and the tax accounts
The company's tax ID arrives with the registration, so corporate income tax needs no separate application. VAT does: registration becomes mandatory within 30 days of turnover crossing THB 1.8 million a year, and in practice it happens much earlier, because sponsoring a foreign work permit effectively requires a VAT-registered company. The standard rate is 7%, filed monthly.
VAT registration is also where the registered address gets tested: the Revenue Department wants a real address with the owner's consent documents, and a thin virtual-office arrangement that passed incorporation can fail here. We set the address up once, to the standard the strictest application will need.
Open the bank account and pay up the capital
The bank account has become the slowest step in a Thai setup. Banks run full due diligence on directors, shareholders, and beneficial owners, typically want the authorized directors present in person, and scrutinize foreign-involved companies harder than local ones, including the legitimacy of the shareholder structure. Branch practice varies widely, and matching the company to the right bank and branch is half the work.
Once open, the paid-up capital lands in the account: the 25% minimum from registration, topped to the full figure your work permits and licenses require. Above THB 5 million in registered capital, the bank certifies that the directors received the funds, and the paper trail from shareholder to company account is part of what keeps the structure defensible.
- Company affidavit, certificate, and the registered objectives from the DBD
- Memorandum of Association and shareholder list
- Passports and details of directors, signatories, and beneficial owners
- Board resolution authorizing the account
- Description of expected activity and transaction profile
Set up work permits and social security
If foreigners will work in the company, including a founder doing the running, the company sponsors their work permits. The standard math: THB 2 million in paid-up capital per work permit and, in practice, four Thai employees per foreign employee, with the ratios relaxed for BOI-promoted companies and holders of certain visa categories. The foreign hire enters on a Non-Immigrant B visa, and the permit follows from the company's documentation.
Hiring anyone triggers the Social Security Office registration within 30 days of the first employee, with contributions of 5% from employer and employee each, capped at THB 750 a month per side. Payroll withholding starts with the first salary, so the registrations and the payroll setup move together.
Activate the company's compliance
Thailand audits everyone: every limited company files audited financial statements annually, regardless of size or activity, with no small-company exemption. The auditor is appointed at the statutory meeting, before the company has traded a baht, and the annual cycle is built around that fact.
- Auditor of record: appointed from formation, since every Thai company files audited statements
- AGM calendar: the annual general meeting within four months of the financial year end, with statements filed to the DBD after approval
- Corporate income tax: the annual return (PND 50) within 150 days of year end, and the half-year return (PND 51) with its prepayment
- Monthly cycle: withholding tax returns, VAT where registered, and social security, every month, with or without activity
- Shareholder list (BOJ 5) filed annually after the AGM and kept consistent with the share register
- License maintenance: BOI conditions and reporting, or FBL conditions, where your route carries them
Our Thailand accounting service then runs the recurring cycle: bookkeeping, the monthly filings, the audit, and the annual returns, handled by the same team that set the company up.

Thailand company registration timeline
The DBD registration completes in about a week once the structure is settled. The bank account is now the slowest standard step, and where your route runs through BOI promotion or a Foreign Business Licence, that approval sets the launch date.
Thailand company registration FAQs
Specific questions about setting up a Thai limited company as a foreigner.
How long does it actually take to register a company in Thailand?
The DBD registration completes in about a week through Biz Regist once the structure is settled: name approval in one to three days, then the filing. The bank account is the slow step at two to four weeks. Where the route runs through BOI promotion or a Foreign Business Licence, add two to six months for that approval, which is why the route decision comes first.
How much does it cost?
Government fees are about THB 5,500 for the registration itself. Service fees depend on the route: a straightforward Thai-majority or unrestricted-activity setup costs much less than a BOI application or Foreign Business Licence. The capital thresholds are not fees; the money goes into your own company's account. Schedule a call and we'll quote your exact case.
Can a foreigner own 100% of a Thai company?
Yes, by the right route: BOI promotion for qualifying activities, a Foreign Business Licence, the US-Thailand Treaty of Amity for American-majority companies, or activities outside the Foreign Business Act's restricted lists, notably manufacturing and export. For restricted services without one of those, the lawful structure is Thai-majority ownership.
What about nominee shareholders?
Thai nominees, locals holding shares on a foreigner's behalf to fake a Thai majority, are illegal under the Foreign Business Act, and enforcement is active: the DBD traces shareholder funds, requires Thai shareholders to document their finances, and prosecutions hit both the foreigner and the nominee. A lawful Thai-majority structure with genuine partners and properly designed control is a different thing entirely, and it's the one we build.
How do I keep control with 49%?
Through the structure, designed lawfully: who holds signing authority as director, what the articles require for key decisions, how share classes and shareholder agreements allocate rights, and how dividends are arranged. Done with real Thai partners, these mechanisms are legitimate corporate design. Structures engineered to disguise foreign ownership are where the legal line sits, and the DBD's scrutiny has sharpened on exactly that distinction.
What is BOI promotion and is it worth it?
Board of Investment promotion for qualifying activities, technology, manufacturing, regional headquarters, and a long list besides, grants 100% foreign ownership, corporate tax holidays, import duty relief, land ownership rights, and streamlined work permits without the standard capital-per-permit math. The cost is a two-to-four-month application and ongoing reporting against your promotion conditions. For eligible businesses planning to hire foreigners, it usually pays for itself.
I'm American. Does the Treaty of Amity help?
Substantially. Companies majority-owned by US citizens can register under the Treaty of Amity and operate most businesses as if Thai, without a Foreign Business Licence. A few sectors stay excluded (land, transport, communications among them), and the certification is its own process, but for qualifying American founders it is one of the cleanest routes available.
How much capital do I really need?
Plan it backwards from your needs. There is no meaningful general minimum, and 25% of shares must be paid up at registration. The real numbers: THB 2 million paid-up per foreign work permit the company sponsors, THB 3 million where it operates under a Foreign Business Licence, and bank evidence of receipt once registered capital exceeds THB 5 million. A founder relocating with a spouse who'll also work needs THB 4 million paid up, not the minimum a cheap package quotes.
Can I work in my own company?
With a work permit, yes, sponsored by your own company once it meets the capital and staffing requirements: THB 2 million paid-up and, in practice, four Thai employees per permit, relaxed under BOI promotion and certain visa schemes. Working without one, even unpaid and even briefly, is an offense that surfaces at renewals and reviews. Get the permit before starting the work.
Why is the bank account the hard part?
Thai banks have tightened onboarding for foreign-involved companies: full due diligence on the shareholder structure, directors present in person at the branch, and practice that varies bank to bank and branch to branch. The same company can be declined at one branch and opened at another, which is why matching the profile to the right bank is part of the service rather than an afterthought.
Does every Thai company need an audit?
Yes. Every Thai limited company files audited financial statements annually, dormant or trading, large or small, with no exemption. The auditor is appointed at the statutory meeting before the company exists, the AGM happens within four months of year end, and the statements file to the DBD after approval. Budget for the audit from day one; there is no exemption to plan for.
When do I need VAT registration?
Legally, within 30 days of turnover crossing THB 1.8 million a year. Practically, earlier: sponsoring a foreign work permit effectively requires a VAT-registered company, and the registration tests your address documentation harder than incorporation does. Once registered, returns file every month with or without sales, so time the registration deliberately.
