Forming a Thai company as a Gulf principal.

The default vehicle

For almost every commercial purpose in Thailand, the vehicle is a private limited company registered with the Department of Business Development at the Ministry of Commerce. It has shareholders, at least one director, a registered address, an objects clause describing what it may do, a registered capital figure, and an obligation to keep accounts, file annually and be audited. Partnerships exist and public companies exist, but a Gulf principal setting up an operating business, a property holding vehicle where that is appropriate, or a service company will in practice be looking at a private limited company. Everything below assumes that.

One point of orientation for Gulf readers used to free zone regimes at home: Thailand has no general free zone offering full foreign ownership across all activities. There are customs free zones and industrial estates with their own privileges, and there is the Board of Investment promotion regime, but there is no equivalent of setting up in a free zone and thereby escaping the general foreign ownership framework. The framework applies, and the exceptions to it are activity specific and applied for.

The ownership question, which comes first

Foreign participation in Thai business is governed principally by the Foreign Business Act, which sets out lists of activities restricted to foreigners. List one is prohibited. List two is restricted and requires Cabinet level permission. List three covers a wide range of service, trading and professional activities and requires a Foreign Business Licence, granted at the discretion of the authorities. A company is treated as foreign, broadly, when half or more of its shares are held by foreign persons, which is why the fifty one to forty nine Thai to foreign shareholding pattern is so common. It is also why that pattern is so often abused.

State this plainly, because it protects you. A Thai majority shareholding must be genuine. Nominee arrangements, in which Thai shareholders hold shares on behalf of a foreigner without real investment or interest, are unlawful, and the authorities do examine the source of Thai shareholders' funds. A structure that only works if nobody looks at it is not a structure. Legitimate routes exist and they are the ones to use: a real Thai partner with a real stake, a Foreign Business Licence where the activity and case support one, Board of Investment promotion where the activity qualifies, or a business model confined to activities not restricted in the first place, of which manufacturing and export are the most important examples. Note also that the Treaty of Amity route, which permits majority American ownership in many sectors, is available to United States nationals only and is not available to Gulf nationals.

Capital, and what the numbers are for

Registered capital in Thailand does more than one job, and confusing the jobs causes trouble. It is a stated figure in the company's registration, it can be partially paid up rather than paid in full at the outset, and it drives several unrelated thresholds. Where a foreign majority company operates under a Foreign Business Licence, minimum capital rules apply, commonly stated as two million baht for a foreign business generally and three million baht per restricted activity licensed, and those figures are to be confirmed currently rather than assumed. Separately, and this is the number that governs daily life, the general rule for work permits ties two million baht of registered capital to each foreign employee's work permit, alongside a requirement for a ratio of Thai employees per foreigner.

The practical implication is that capital should be sized against the number of foreign people who will need to work in Thailand, not merely against the cash the business needs. A principal who registers a modest capital because the business is asset light, then discovers three months later that he cannot obtain work permits for his own general manager and finance controller, has to increase capital and refile, which costs time he did not budget. Decide the headcount question first. Board of Investment promoted companies are treated differently on these ratios, which is one of the strongest practical arguments for promotion where it is available.

Directors, shareholders and the people who sign

A Thai limited company needs at least one director, and there is no general requirement that a director be Thai. A foreign director can hold the role without living in Thailand, though a foreign director who actually performs work in Thailand requires a work permit to do so, which is a distinction people miss. The articles of association set out who may bind the company and how: a single director signing, two directors signing jointly, or a director signing with the company seal. Get this right at incorporation, because the signing rule is what banks, the Land Department and counterparties will check, and amending it later is a filing exercise nobody enjoys.

On the shareholder side, share classes, voting rights, dividend rights and pre emption can be shaped in the articles and in a shareholders agreement, and a Gulf principal in a genuine joint venture should expect to negotiate all of them properly rather than accepting a standard form. Reserved matters, deadlock provisions, transfer restrictions, exit mechanics and the treatment of a shareholder's death or incapacity are the clauses that matter years later. Our separate guide to shareholder agreements in Thailand treats this in full, and our guide to director liability sets out what a director is personally exposed to, which every principal appointing a family member as director should read first.

The registration sequence

• Reserve the company name with the Department of Business Development, in Thai and usually in English
• Settle the objects clause so it covers what the business will actually do, including future activity you can foresee
• Prepare the memorandum of association, articles, shareholder list and director details
• Hold the statutory meeting and complete subscription formalities
• File for registration and obtain the company registration certificate and affidavit
• Register for tax with the Revenue Department and obtain a tax identification number
• Register for VAT where turnover or activity requires it, or voluntarily where the business needs it
• Register with the Social Security Office once employees are engaged
• Open the corporate bank account, which is a separate process with its own timeline and its own patience requirement
• Apply for any activity licences the business needs, which may include food, hotel, transport, import or sector specific permits

The filings themselves can move quickly. What lengthens the timeline for a Gulf principal is document preparation from abroad: passports and corporate documents from the home jurisdiction generally need notarisation and legalisation, translation into Thai by an accepted translator, and consular or embassy attestation depending on the document and the receiving office. Start that stack early. It is routinely the critical path, and it is the one part nobody can accelerate on your behalf.

Work permits follow the company, not the person

A foreign national working in Thailand needs both the right visa category, usually a Non Immigrant B for employment, and a work permit issued to a specific employer for specific work at a specific location. The company must exist, be registered, be capitalised appropriately and generally show Thai employees before it can sponsor a foreigner. That ordering matters: the company comes first, the permits follow. The Board of Investment route, the Smart Visa and the Long Term Resident visa each alter the picture for qualifying businesses and qualifying individuals, and our main visa guides cover those categories properly. A principal who intends to visit rather than work should not assume that a visa exempt entry covers any work activity, because it does not.

Where our business guides take over

This piece is orientation for a Gulf principal deciding whether and how to form a Thai entity. The detail lives elsewhere in our business library: the Foreign Business Act is treated fully in its own guide, the annual compliance calendar sets out what a Thai company must file and when, the accounting and audit guide explains the bookkeeping and audit obligations, the corporate tax and VAT guides cover the tax side, the hiring and labour law guides cover employment, and the representative office guide covers the lighter alternative. None of that replaces appointing your own Thai counsel and your own auditor. It does mean you will arrive at that first meeting knowing what to ask.

Capital thresholds, foreign business classifications and work permit ratios are set by regulation and change. Verify company registration requirements with the Department of Business Development at the Ministry of Commerce, foreign business classification and licensing with the same department, tax registration with the Revenue Department, and work permit and visa requirements with the Department of Employment and the Immigration Bureau. Appoint your own Thai legal and accounting advisers before incorporating; do not rely on a counterparty's or an introducer's firm.

This briefing is general information, not legal, tax or investment advice. Thai rules change frequently and individual cases differ. Verify current requirements with the relevant authorities, including the Immigration Bureau, the Board of Investment, the Land Department, the Department of Business Development and the Revenue Department, and take advice on your own facts before acting.
