The lawful routes to a compliant Thai company.

Start from the activity, not from the shares

Every regularisation begins with the same question, and it is not a question about shareholding. It is what the business actually does, described precisely enough for Thai counsel to classify it against the Foreign Business Act. A surprising number of reviews end early and happily at this stage, because the activity turns out not to be restricted at all and the Thai majority was never necessary. Where that is the case the remedy can be relatively simple: the foreign owner takes the shareholding the business always justified, and a structure that was fragile becomes ordinary.

Where the activity is restricted, the routes below apply. They are not alternatives in the abstract. Each suits a particular combination of activity, capital, nationality and timescale, and the choice is a legal judgement made on your facts by counsel you instruct, not a preference expressed by an owner.

Route one: genuine Thai investment

The first route is to make the Thai majority real. That means Thai investors who subscribe with their own money, whose funds can be traced from their own accounts, who take genuine economic risk in the business, and who participate in governance in a way that would withstand a stranger's examination. It is not a documentation exercise and it cannot be achieved by improving the paperwork around the existing holders.

Owners underestimate the commercial consequence. Real investors want real terms: a price for their shares, information rights, a say in decisions, and a share of profits proportionate to their holding. That is precisely what makes the arrangement lawful, and it is also why some owners conclude the route is not for them. Where it works, it usually works best when the Thai partner brings something the business needs anyway, such as premises, licences in their own field, distribution or local management, so that the relationship has a commercial logic rather than an administrative one.

Route two: promotion by the Board of Investment

Promotion by the Board of Investment is the strongest route where the activity qualifies. Promoted activities can generally be conducted with majority or full foreign ownership, and promotion may carry rights to hold land used in the promoted business, together with relief from the usual Thai to foreign employee ratio and streamlined visa and work permit handling. Certain activities also attract tax incentives, though these vary considerably and should never be assumed.

The constraint is eligibility. Promotion is granted for defined categories of activity, weighted toward manufacturing, technology, research, targeted services and other sectors the Board wishes to encourage. A conventional retail, hospitality or property holding business will usually not qualify, and no amount of redescription changes that. Where an activity is genuinely eligible, expect a feasibility assessment, a real application with financial projections and employment commitments, and a period measured in months rather than weeks, followed by ongoing conditions that must actually be met.

Route three: restructuring into a permitted activity

Sometimes the right answer is to change the business rather than the ownership. A group can separate a restricted activity from an unrestricted one, so that the foreign owned entity does only what it may lawfully do and any restricted element is conducted by a genuinely Thai owned business at arm's length, on commercial terms, with real independence. Manufacturing and export activities are treated differently from domestic services, and moving the centre of value can change the classification.

This route demands discipline, because a separation that exists only on paper is no separation at all. If the supposedly independent Thai business is funded by the foreign owner, controlled by the foreign owner and holds no risk, the restructuring has changed the diagram and not the facts. Counsel will say so, and an owner who wants a real answer should want to hear it.

Route four: a Foreign Business Licence

Where the activity falls within the third list, a Foreign Business Licence permits a foreign majority to conduct it. The application is considered by the Foreign Business Committee and granted at official discretion, with weight given to the benefit to the Thai economy, the transfer of technology or knowledge, employment, and the effect on Thai businesses in the same field. Minimum capital requirements apply and are higher than for unrestricted operation.

It is a real process with a real possibility of refusal, and it is not a route for a business whose only distinguishing feature is that it would prefer not to have a Thai partner. Where a company genuinely brings capability that is scarce locally, the case can be made properly and is worth making. Expect months, not weeks, and expect to answer questions about the company's history as part of it.

Route five: the Treaty of Amity, for United States owners

American nationals and companies owned by them can register under the Treaty of Amity and Economic Relations, which permits majority or full United States ownership across many sectors that would otherwise require a licence. Registration requires certification of the United States ownership and management position and then registration with the Thai authorities. It is a genuine and well used route where it is available.

Its limits must be stated as clearly as its benefits. It is available only to United States persons and to companies genuinely majority owned and controlled by them, so it cannot be borrowed by a partner of another nationality. Several sectors are excluded, including communications, transport, fiduciary functions, banking involving depository functions, and exploitation of land and natural resources. Above all, it confers no right to own land. An American owner who registers under the Treaty still holds property through the ordinary lawful routes and not otherwise.

Route six: an orderly wind down or sale

For some companies the honest conclusion is that there is no business worth restructuring. A dormant vehicle holding a house, a venture that stopped trading years ago, a company kept alive only because closing it seemed like effort: for these, a solvent liquidation with proper tax clearance, or a sale of the underlying business or asset to a compliant buyer, is the cleanest outcome available. It is treated in detail in our article on closing or restructuring a Thai company cleanly.

The one option that is never orderly is abandonment. A company left unfiled continues to accrue penalties, keeps its directors in position with their obligations intact, and eventually becomes a much harder problem to unwind, often at the worst possible moment for the family that inherits it.

Comparing the routes, and the order of the steps

Most regularisations involve more than one filing, and the order in which they are made can determine how the whole exercise is received. Since 1 April 2026 amendment filings have been reported to attract source of funds scrutiny, so a change made in isolation, before the wider position has been settled with counsel, can put the company in front of a registrar with only half an answer. That is an argument for planning the sequence with your lawyer first, not for avoiding filings or delaying anything. Delay is not a strategy and it is not one this office would support.

Where an owner believes the company may already be exposed, the sequencing conversation starts with counsel and nowhere else. Instruct qualified Thai lawyers immediately, give them the complete picture including the documents that are difficult to hand over, and let them advise on what is disclosed, corrected and filed, and in what order. Thai shareholders and directors who may be exposed under Section 36 should be told to take their own independent advice.

Asia Global Partners is a private office and not a law firm, and gives no legal or tax advice. The office convenes qualified Thai counsel, accountants and valuers, coordinates them through what is usually a months long process, and remains the single accountable relationship for the client. A confidential structure review is the normal way to begin. Owners with reporting or tax obligations at home should bring those advisers into the same conversation from the start.

This article is general information as at August 2026 and is not legal or tax advice. Routes described here depend entirely on your own facts. Asia Global Partners is a private office, not a law firm. Instruct qualified Thai counsel independently before acting, verify licensing and filing requirements with the Department of Business Development, verify promotion eligibility with the Board of Investment, and verify tax consequences 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.
