Register a company in Thailand.
Limited companies, joint ventures, branch offices, representative offices. We scope the right structure, file with the DBD, and stay on as your corporate secretary so the company keeps running cleanly after day one.
What does registering a company in Thailand involve?
Registration creates a Thai legal entity that can trade, hire, open a bank account, and sponsor visas. The mechanics are well-trodden; the judgement is in choosing the structure and ownership split before you file.
Every entity is registered with the Department of Business Development under the Ministry of Commerce — and since mid-2025 those filings run through the DBD's online Biz Regist platform with electronic identity verification. A standard Thai limited company can be live in roughly 7–10 business days once the documents are ready; a representative office takes about a month and a branch office around three. What sets the timeline and the cost is rarely the paperwork — it is whether foreign ownership, a Foreign Business License, BOI promotion, or sector licenses come into play.
Three common ways to set up in Thailand.
Most foreign businesses choose between a limited company, a representative office, and a branch office. Each differs in what it may do, how it is owned, and how long it takes.
Limited company Most popular
The default for most businesses — a trading entity, fast to register, and unrestricted in activity when Thai-majority. It needs at least two shareholders; capital depends on ownership and on any foreign work permits rather than a fixed minimum. Set up in around 7–10 business days.
Learn moreRepresentative office
A non-trading presence for studying the market and sourcing — up to 100% foreign-owned, no shareholders, confined to five permitted non-revenue activities. Allow about a month and THB 2 million in funding.
Learn moreBranch office
Extends a foreign head office into Thailand as the same legal entity — up to 100% foreign-owned with no separate shareholders, but its activities are bounded by the Foreign Business Act. Allow around three months and at least THB 3 million in capital.
Learn moreWhat every registration needs.
A handful of building blocks set up the entity; a second set of registrations keeps it compliant from day one.
To register the company
- A local registered business address
- At least one director
- At least two shareholders — the statutory minimum since 2023
- Registered capital suited to the structure and to any foreign work permits
- A corporate bank account once the entity exists
Capital rules of thumb: a Thai-majority company with no foreign staff has no fixed minimum; a company sponsoring foreign work permits needs about THB 2 million of capital per permit (THB 1 million if the foreigner is married to a Thai); a foreign-majority company in a restricted activity starts at THB 3 million.
Registrations & ongoing obligations
- Tax ID, and VAT registration — mandatory once turnover passes THB 1.8 million a year, or when sponsoring foreign staff
- Social-security registration for employees
- Any sector-specific business licenses
- A Foreign Business License where the company is foreign-majority in a restricted activity
- Monthly and annual bookkeeping, tax and withholding filings, and the annual audit
Routes to full control as a foreigner.
Foreigners can own 100% of a Thai company either by operating in an unrestricted activity or by using a specific structure or state incentive.
BOI promotion Popular
A company operating in an activity promoted by the Board of Investment. Alongside full ownership it can draw on tax and non-tax incentives and other concessions.
US Treaty of Amity
US citizens can hold 100% of a Thai company under the bilateral Treaty of Amity between the United States and Thailand.
Foreign Business License
A limited company can reach full foreign ownership by securing a Foreign Business License — though its activities then remain bounded by the Foreign Business Act.
Representative, branch & regional offices
Other registrations for foreign-registered companies are possible, each with its own limits on operations and on earning revenue.
Export company
A limited company whose sole purpose is to export tangible goods or materials out of Thailand.
Manufacturing company
A limited company whose sole purpose is to manufacture goods and sell them outside Thailand.
The registration process, step by step.
From reserving the name to switching on visas and work permits — the official sequence a new company follows.
Reserve the company name
The name is searched and reserved with the DBD; the reservation holds for 30 days.
Prepare, sign & file
We gather the details, draft the memorandum and articles, collect signatures, and submit to the DBD.
Company registration
The DBD issues the registration documents and the company/tax ID; timing depends on the specifics of the business.
Open a corporate bank account
Bank, branch, account type, and authorised signatories are settled and the account opened.
VAT & Social Security registration
VAT is registered where foreign staff are employed or turnover exceeds THB 1.8 million; employees are enrolled with the Social Security Office.
Visas & work permits
Non-B visas and work permits are arranged for foreign directors and staff, with the visa extended to one year once the work permit is granted.
How we help you incorporate.
Registration is typically completed by the DBD within about 7–10 business days once documents are ready. The harder question is which structure — and the answer changes how the business can be owned, taxed, and operated for years afterwards.
We start every engagement with a 30-minute conversation about what you actually plan to do — the activity, the ownership split between Thai and foreign shareholders, where the customers and revenue come from, and what visas the founders need. The right answer is sometimes a standard Thai Limited Company, sometimes a BOI-promoted entity, sometimes a Treaty of Amity company for US citizens, and occasionally a branch office or representative office.
Once the structure is locked, the incorporation itself is procedural. We handle name reservation, the Memorandum of Association, the statutory meeting, share allocation, DBD registration, VAT registration where applicable, and the corporate seal. Bank account opening — historically the slowest step — is the one part we cannot guarantee, but we walk you through it with the right introductions.

How long does company registration take?
A standard Thai Limited Company can be registered within 7–10 business days once we have the documents. BOI applications and Foreign Business Licenses take longer — typically 30–90 days depending on category.
Can a foreigner own 100% of a Thai company?
Only with BOI promotion, a Foreign Business License, Treaty of Amity protection (US citizens), or in activities not restricted under the Foreign Business Act. Otherwise the standard ratio is 49% foreign / 51% Thai shareholding. We help you choose the right route during the discovery call.
Do you arrange the bank account?
We make the introductions, prepare the supporting documents, and accompany you to the bank. The account itself is the bank's decision, and since 2025 it has become slower and more selective — in practice usually around a month for a newly registered company, sometimes longer (see the next question).
How hard is it to open a corporate bank account in 2026?
Harder than it used to be, but very doable with the right preparation. Following the Bank of Thailand's tightening of AML and KYC rules — a response to fraudulent 'mule accounts' — banks now scrutinise new corporate accounts far more closely, and generally want to see a properly registered, genuinely operating Thai company before they open one. This sits alongside the new DBD source-of-funds rules in force from 1 January 2026. In practice, expect roughly one month from a complete application, though some banks take longer. The account must be opened in Thailand in person by an authorised company signatory; it cannot be done online or from overseas. Companies with directors or shareholders from sanctioned or high-risk jurisdictions can face significantly more scrutiny, and occasionally refusal. Banks retain full discretion, so outcomes vary by branch. We prepare your documents, brief you on each bank's current stance, and accompany you to maximise your chances of a smooth opening. Information current as of June 2026 — please confirm the latest position with us.
Which bank do foreign-owned companies usually open with?
Bangkok Bank, Kasikorn (KBank), SCB, and Krungsri are the common choices. We match the bank and branch to your business and steer you toward those that have handled similar foreign-owned accounts smoothly, rather than leaving you to find that out at the counter.
Does a director have to be in Thailand to open the account?
Yes. Every major Thai bank now requires the authorised signatory to appear in person at the branch with original identification — there is no fully remote or online corporate account opening for a newly registered company. We book the appointment and go with you.
What does the bank need to see in 2026?
The company affidavit issued within the last 30 days, the MOA and shareholder list (Bor Or Jor 5), a board resolution naming the signatories, the corporate seal, and each signatory's passport. Under tighter Bank of Thailand and AMLO checks, banks now also ask about the source of funds, expected turnover, and the nature of the business before approving — so we prepare those answers with you in advance.
Can we open the account before the directors' work permits are issued?
Usually yes — the account can be opened on the registered company and the signatory's passport, often while they are still on a Non-B visa, with the work permit following. A few branches prefer to see the work permit first, so we confirm the requirement with the chosen bank before booking the appointment.
Do you handle the work permit for the directors at the same time?
Yes. Once the company is registered and the VAT registration is complete, we can begin the work permit and Non-B visa applications. The two flows are usually scoped together from the start.
What about the 2026 DBD source-of-funds rules?
Since 1 January 2026, under DBD Order No. 2/2568, the Thai shareholders of a company with foreign involvement must evidence the source of their invested capital — in practice, around three months of bank statements from the account that actually paid for the shares, showing the matching transfer. It applies where foreign shareholders hold less than half the company (the standard 49/51 structure) or where there is no foreign shareholder but a foreigner is an authorised director. We prepare and handle this capital-substantiation documentation as part of every such incorporation, so your filing meets the current requirement.
