Ask five people how long it takes to register a company in Thailand and you’ll get five different answers — because the honest answer depends entirely on who owns the company. A 100% Thai-owned business can walk out of the Department of Business Development (DBD) with a company registration certificate in a matter of days. A foreign-majority business that needs a Foreign Business License, on the other hand, is looking at a different process altogether, with its own approval queue and its own timeline.
This guide breaks down what actually happens at each stage of Thai company registration, how long each step realistically takes, and — more importantly — which factors are within your control and which aren’t. By the end, you’ll know whether your business falls into the “days” category or the “weeks to months” category, and what you can do to land on the faster end of either one.
Thepphonglaw works with foreign founders and investors setting up companies across Thailand, from straightforward Thai-majority structures to BOI-promoted ventures with 100% foreign ownership. The timelines below reflect what we typically see play out for clients, not a best-case scenario pulled from a government brochure.
Stage | Typical Timeframe |
Company name reservation | 1-3 business days |
Memorandum of Association (MOA) filing | 3–5 working days, subject to the completeness of the client’s information and the approval of the officers involved. |
Company registration at DBD | 1–5 working days, subject to the completeness of the client’s information and the approval of the officers involved. |
Corporate bank account opening | 1-4 weeks (bank-dependent) |
Tax ID and VAT registration | A few days to 30 days after incorporation |
100% Thai-owned company, start to finish | About 1-2 weeks |
Foreign-majority company requiring a Foreign Business License | Roughly 4-6 months, sometimes longer |
BOI-promoted company (100% foreign ownership eligible) | Roughly 4-6 months for BOI approval, then registration proceeds as above |
These are working ranges, not guarantees — a specific company’s timeline depends on document readiness, business activity, and which government office is processing the file that month. Treat the table as a planning baseline, then read on for what actually drives the difference between the fast lane and the slow one.
Every Thai limited company, regardless of ownership structure, passes through the same core registration steps at the DBD. The variation in total timeline comes from what happens around these steps, not the steps themselves.
The process starts with reserving a company name through the DBD’s online system. Officers check the proposed name against existing registered companies and a list of restricted or reserved words. A clean, distinctive name is typically approved within 1-3 business days; a name that’s too similar to an existing company or uses a restricted word gets rejected and has to be resubmitted, adding days back onto the clock.
Once the name is reserved, the founders file the Memorandum of Association, which sets out the company’s objectives, registered capital, and the names of the promoters. This is filed the 3-5 working days and subject to the completeness of the client’s information and the approval of the officers involved.The name reservation clears, assuming the shareholder and director information is ready.
Before registration, the company holds a statutory meeting to adopt the articles of association, appoint directors, and confirm share allocations. The minimum share capital payment of at least 25% is mandatory for all shareholders, both Thai and foreign.
With the MOA, statutory meeting minutes, and director/shareholder documents in hand, the actual registration filing at the DBD is usually processed within a single business day. This is the step most people picture when they think of “registering a company,” and it genuinely is fast — the delay almost always happens before or after this point, not during it.
Registration certificate in hand, the company still needs a corporate bank account and a tax identification number before it can operate. Banks apply their own know-your-customer (KYC) checks, particularly for foreign directors and shareholders, which is where a company that registered in a week can still be waiting a month before it can actually receive payments. VAT registration, if the business exceeds the turnover threshold or opts in voluntarily, is a separate filing on top of the basic tax ID.
If the steps above are all fast, why do so many foreign-owned companies take months instead of weeks? Four factors account for nearly every delay we see.
Thailand’s Foreign Business Act restricts foreign majority ownership in many business categories unless the company obtains a Foreign Business License (FBL) or qualifies for an exemption (such as US-Thai Treaty of Amity status, for eligible American-owned businesses, or a BOI promotion). An FBL application is reviewed by a separate committee with its own processing calendar, and realistically adds one to several months on top of the standard registration steps above. This is the single biggest reason “how long does it take” has no one-size-fits-all answer.
Name mismatches between a shareholder’s passport and other submitted documents, missing notarizations for documents executed abroad, or an unclear description of business activities are the most common reasons a DBD filing bounces back for correction. Each round of correction adds days, and a filing that gets rejected twice can lose two to three weeks that a complete submission would never have spent.
Founders sometimes pick a structure based on what’s fastest to file, without checking whether it actually supports what they want to do next — hire foreign staff, open a second branch, or apply for BOI privileges later. Untangling a structure that doesn’t fit costs far more time than getting it right at the outset. Our guide to the types of companies in Thailand walks through which structure fits which situation before you file anything.
Founders often measure “registering a company” by the DBD certificate date and are caught off guard when the bank account — the thing that actually lets the business operate — takes weeks longer. Building the bank’s KYC timeline into your planning from day one avoids a business that’s legally registered but functionally stalled.
The DBD registration steps look similar on paper for a private limited company, a Thai-foreign joint venture, a representative office, or a BOI-promoted entity, but the surrounding approvals differ sharply. A representative office, for instance, doesn’t generate revenue in Thailand and follows a narrower notification process; a BOI-promoted company front-loads a longer approval period in exchange for tax privileges and, in eligible categories, full foreign ownership without an FBL. If you haven’t settled on a structure yet, it’s worth reading through the types of companies in Thailand guide alongside this one — the two decisions (which structure, how long it takes) aren’t separable.
The single biggest lever founders actually control is document readiness. A law firm that has filed hundreds of these registrations knows exactly which documents the DBD wants notarized, which shareholder details cause rejections, and how to pre-empt an FBL committee’s likely questions before submission rather than after a rejection. That preparation work — done once, correctly, before anything is filed — is usually the difference between a two-week registration and a two-month one for the same business.
This is the kind of groundwork our Thailand Company Registration Services team handles for clients from the first consultation: confirming the right structure, assembling a complete document package, and managing the DBD and, where relevant, FBL or BOI submissions end to end, so founders aren’t discovering a missing notarization three weeks into the process.
A registration certificate is the start of compliance obligations, not the end of them. Newly registered companies need bookkeeping systems in place from month one, a decision on VAT registration if turnover is expected to cross the threshold, and — if the company plans to employ foreign staff — a separate work permit process that runs independently of company registration. If hiring foreign employees is part of the plan, it’s worth reviewing what’s required well before the registration certificate arrives, since work permit applications depend on the company already being registered and adequately capitalized. Our accounting and financial services team typically starts this setup in parallel with the final registration steps, so there’s no gap between “company registered” and “company compliant.”
If there’s one takeaway from this guide, it’s that “how long does it take to register a company in Thailand” has two honest answers, not one: about one to two weeks for a straightforward, fully Thai-owned structure with clean documentation, and closer to two to four months (sometimes more) once foreign ownership triggers a Foreign Business License or BOI application. Neither timeline is fixed — document readiness and structural planning move the needle more than any government office does.
FAQs about How Long Does It Take to Register a Company
The DBD registration filing itself can be processed in a single day once your name reservation, MOA, and supporting documents are complete and correct. Getting to that point — and then opening a functioning bank account afterward — realistically takes longer, even for straightforward Thai-owned companies.
Not always. Foreign-owned businesses that qualify for an exemption, such as eligible Treaty of Amity companies for US nationals or a BOI promotion in an eligible category, can avoid the standard Foreign Business License process. Without an exemption, though, foreign-majority ownership in a restricted business category does require FBL approval, which adds significant time.
Minimum registered capital requirements vary by structure and, for companies employing foreign staff, by how many work permits the company intends to support. This is worth confirming with a legal advisor before filing, since it affects both the registration paperwork and later work permit eligibility.
You can’t control the committee’s review calendar, but a complete, well-prepared application with clear supporting evidence for why the business should be approved meaningfully reduces the odds of a request for additional information — which is what usually stretches an FBL timeline from two months toward four.
Nothing legally requires a lawyer for a straightforward Thai-majority registration. In practice, most foreign founders use one anyway, because the cost of a rejected filing or a structure that doesn’t fit the business’s real plans (hiring foreign staff, seeking BOI privileges, opening additional branches) is almost always higher than the advisory fee would have been.
