Substance, and what your company can actually show.

The question has changed, and so has the answer

For twenty years a great many foreign owned businesses in Thailand were arranged the same way. A Thai limited company was incorporated. Thai nationals were entered on the shareholder register for fifty one percent or more of the shares. The foreign principal held the remainder, along with everything that mattered in practice: the bank mandate, the authorised director's signature, the customer relationships, the funding and the profit. The arrangement was so widespread that repetition lent it the appearance of legitimacy. It was sold as a product by people who knew what it was, and bought by owners who were told, quite wrongly, that it was simply how business is done here.

It was never lawful. Nothing about it has become unlawful recently, because the Foreign Business Act B.E. 2542 has prohibited it since 1999 and Section 36 has always made it an offence for a Thai person to hold shares on a foreigner's behalf. What changed in 2026 is not the rule but the capacity of the state to apply it. The Department of Business Development now requires documentary proof of where shareholder money came from, and it now runs that information against data it already holds. The practical question for an owner is therefore no longer whether the structure was common, or whether anyone has ever complained about it. It is narrower and far less comfortable: what can this company actually show?

That question has a good answer for some companies and a poor one for others, and the difference is rarely about intention. Plenty of foreign owners built genuine businesses, employed real people, paid real tax, and inherited a defective shareholding structure from an adviser at the outset without ever revisiting it. Plenty of others hold a villa in a company that has traded nothing for eight years. The law does not grade on effort, but the range of lawful options available to an owner is very much wider while nothing is live. That is the whole reason to look now rather than later.

What substance actually means

Substance is not a mood, an impression, or a file of well drafted documents. It is a set of facts that either exist or do not exist, and each of them leaves a trace somewhere outside the company's own paperwork: in a bank, at the Revenue Department, in the Social Security system, on a lease, in a supplier's ledger. An examiner is not reading your company's story. They are checking whether the traces line up.

• Thai capital that was genuinely subscribed and genuinely paid, from the shareholder's own resources, traceable through that shareholder's own bank account.
• Thai shareholders with demonstrable financial capacity for the shareholding they hold, and a real economic interest in the outcome: they gain if the business does well and they lose if it does not.
• Directors who actually direct: who attend, who decide, who question, and whose decisions appear in minutes that reflect what was really discussed rather than a template signed once a year.
• Employees who are genuinely employed, on real terms, registered for social security, paid through payroll with tax withheld.
• Premises the company genuinely occupies under a lease or ownership in its own name, at a rent that a stranger would pay.
• Filings made on time: audited financial statements, the annual shareholder list, corporate income tax returns, VAT and withholding filings.
• Accounts that reflect the real economics of the business, including how it is funded and who ultimately benefits from its profits.
• An objects clause and any required licences that match what the company actually does, not what it was expected to do at incorporation.

The first two items carry most of the weight, and they are the ones most often absent. A Thai shareholder who never paid for their shares, or who was funded to pay for them by the foreign principal, or who has signed an undated share transfer, a loan agreement, a proxy or a pledge that strips the shareholding of economic meaning, is not a shareholder in any sense the Act recognises. Section 36 addresses precisely that situation, and it does so regardless of how carefully the surrounding documents were drafted. Documents that reverse the economic reality of a shareholding are evidence of the arrangement, not protection from it.

The remaining items matter because they are cumulative. A single Thai shareholder with modest means is unremarkable. A company with no employees, no premises of its own, no trading activity, a nominal Thai majority whose capital arrived and left on the same day, and a foreign director holding the sole bank mandate is not a series of small oddities. It is a pattern, and pattern is what data analysis is good at finding.

Section 36, stated accurately

Section 36 of the Foreign Business Act provides that a Thai national or Thai entity who holds shares on behalf of a foreigner, in order to allow that foreigner to operate a business reserved to Thai nationals, commits an offence. So does a foreigner who allows or takes part in that arrangement. The penalty is imprisonment for a term not exceeding three years, a fine of between 100,000 and 1,000,000 baht, or both, and the court may order the arrangement to cease, with a further daily fine for continuing non compliance.

The point that most owners have never absorbed is that the liability falls on both sides. The Thai shareholder is not a service provider standing outside the risk. They are a person exposed to the same criminal provision as the principal, frequently for a fee of a few thousand baht a year, and frequently without ever having had the position explained to them in their own language by a lawyer acting for them rather than for the company. Foreign owners who would never knowingly expose an employee to prosecution have often done exactly that, out of ignorance rather than indifference. It is one of the strongest practical arguments for regularising early.

Beyond Section 36 itself, advisers in this market report further consequences that follow in practice: separate false statement offences under the Penal Code where declarations to the registrar did not reflect the facts, dissolution of the company by court order, and compulsory disposal of land held through a nominee arrangement. Whether any of these arises in a given case is a question of Thai law and Thai facts, and it is a question for counsel, not for a website.

What the Department of Business Development changed in 2026

Two administrative changes, reported during 2026, altered the practical position more than any amendment to the Act would have done. From 1 January 2026 the Department of Business Development has required documentary proof of source of funds on the incorporation of a new Thai company, with registrars verifying that each Thai shareholder has genuine financial capacity for the paid up capital declared, supported by bank statements. From 1 April 2026 the same checks were reported to extend to company amendment filings.

The second date is the one that matters to companies already in existence. An amendment filing is an ordinary administrative act: a change of director, a change of registered address, a transfer or issue of shares, a change to the objects. Structures that have sat undisturbed for a decade are brought into view not by an investigation but by routine housekeeping. Alongside this, the Department has been reported to be examining tens of thousands of companies for nominee indicators, with Phuket, Koh Samui and Koh Phangan named as focus areas, and to be using data analysis across company registration records and land transaction records to identify patterns. Sectors reported as higher risk include tourism, real estate and land trading, hotels and resorts, agriculture, logistics and e-commerce, and construction.

All of that should be read as the reported direction of travel in August 2026, not as settled and permanent law. Administrative practice moves quickly and unevenly. The current position on any specific filing should be confirmed with the Department of Business Development and with instructed Thai counsel before you rely on it.

Why a decade of quiet filings is not protection

Owners frequently reason from the absence of trouble. The company has filed every year, nobody has asked anything, therefore the position is stable. That inference held while examination depended on someone making a complaint. It holds much less well when the trigger is an ordinary event that the owner initiates themselves, or that life imposes.

• An amendment filing: a director resigns, an address changes, shares move, the objects are updated.
• A sale of the business or of the property the company holds, where the buyer's lawyers conduct proper due diligence.
• A refinance or a new lending facility, where the lender examines ownership and control.
• A bank review of the company account, or a source of funds enquiry on a large inbound or outbound payment.
• A death, where an estate must be administered and the true ownership of shares becomes a question for a court.
• A divorce, where matrimonial disclosure reaches the structure.
• A dispute between the principal and the Thai shareholder, or between business partners, where one side has an incentive to describe the arrangement accurately.

Each of these is normal. Several of them are things an owner wants to do. The consistent feature is that the owner does not control the timing of most of them, and in the ones they do control, the structure comes under examination at the precise moment they need the transaction to complete. An owner who reviews voluntarily, while nothing is live, keeps the full range of lawful options and the time to use them. An owner who reviews under pressure has fewer options, worse pricing, and counterparties who now know more than they did.

Reading your own company with an examiner's eye

It is a useful discipline to look at your own company as a stranger would, element by element, and to be honest about which column each element falls into. The purpose of doing this is to know what needs to be fixed, and to give your lawyer a complete and accurate picture. It is emphatically not to identify what looks weak so that it can be made to look stronger.

One rule governs the whole exercise, and there is no exception to it. Where records do not reflect reality, the answer is never to adjust the records. Backdating, reconstructing, replacing or tidying documents converts a regulatory problem into a much more serious one, and it does so at the exact moment when the owner most needs credibility. The lawful answer is to instruct qualified Thai counsel, to give them everything without editing, including the side agreements and the uncomfortable emails, and to let them advise on correction and disclosure through the proper channels.

What a compliant structure looks like

The constructive half of this subject is more encouraging than owners expect. There are several genuinely compliant ways to hold and operate a business in Thailand as a foreigner, and most owners who look seriously find that at least one of them fits, sometimes with better tax and financing outcomes than the arrangement they are leaving.

• A Thai majority company where the Thai investment is real: partners who contributed their own capital, who take genuine economic risk, and who participate in governance in a way that would survive a stranger's examination.
• A company promoted by the Board of Investment, where the promoted activity permits majority or full foreign ownership and, for some activities, rights to hold land used in the promoted business.
• A restructuring of the business into an activity that is not reserved, so that foreign ownership raises no Foreign Business Act question at all.
• A Foreign Business Licence, where the activity falls in the third list and the case for granting can be made.
• For United States nationals and United States owned companies, registration under the Treaty of Amity, which permits majority United States ownership in many sectors but confers no right to own land.
• For residential property specifically, the lawful holdings: a condominium unit in freehold within the building's forty nine percent foreign quota with funds remitted from abroad and evidenced by the bank, or a registered lease, usufruct, superficies or right of habitation, each with its own real limits.
• An orderly solvent wind down or sale, where the activity no longer justifies a Thai vehicle at all.

None of these is a formality and none is instant. Introducing genuine Thai investment means finding investors who actually want the risk, and accepting that they will want terms. Board of Investment promotion means an eligible activity and a real application. A Foreign Business Licence is discretionary and is not granted merely because the alternative is inconvenient. The Treaty of Amity is limited to United States persons and excludes several sectors, land among them. The honest summary is that the compliant routes cost more and take longer than the arrangement they replace, and that they are the only ones that leave an owner with an asset they can sell, finance, insure and pass on.

Where this leaves an owner

If you read the earlier sections and recognised your own company in the wrong column, the guidance is short and it does not vary. Instruct qualified Thai counsel now, before the next filing, and be completely open with them: the side letters, the funding of the Thai shareholders' subscription, the undated transfers, the informal understandings. Lawyers can work with facts they know. They cannot protect a client from facts they discover late, and an incomplete instruction is the most common reason a solvable position becomes an unsolvable one. Where the Thai shareholders may themselves be exposed, they need their own independent advice, because their interests and yours are not identical.

Asia Global Partners is a private office. It is not a law firm and it gives no legal or tax advice. What the office does is convene and coordinate: instructing qualified Thai counsel on your behalf, bringing in accountants and valuers where they are needed, holding the process together across the months it usually takes, and remaining the single accountable relationship while specialists do the specialist work. Where a client wants a starting point, a confidential structure review is the usual one. What the office cannot do, and will not pretend to do, is determine whether an arrangement is lawful or speak for any Thai authority.

This article is general information about Thai law and administrative practice as reported in August 2026. It is not legal advice, and nothing in it should be relied on for your own facts. Asia Global Partners is a private office and not a law firm. Anyone reviewing a Thai company structure should instruct qualified Thai counsel independently, and should verify the current filing and source of funds requirements with the Department of Business Development, land questions with the Land Department, promotion questions with the Board of Investment, and tax questions with the Revenue Department.

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.
