For years, a common workaround let foreign entrepreneurs hold effective control of a Thai company while a Thai national sat on paper as the majority shareholder. That workaround is now under the closest scrutiny it’s faced in over two decades.
What Actually Changed in 2026
DBD Order No. 1/2569, effective 1 April 2026, introduced what’s being called an “actual control” test alongside the traditional 50% shareholding threshold that’s governed the Foreign Business Act since 1999.
The Old Rule Was Simple. The New One Isn’t.
Previously, keeping foreign shareholding at or below 49% was generally enough to avoid classification as a foreign company. Under the 2026 reforms, regulators now look past the share register itself, examining board composition, veto rights, management agreements, and financing arrangements to determine whether a company is actually foreign-controlled regardless of who technically holds the shares.
New Documentation Requirements
From 1 January 2026, any company registration involving foreign participation requires Thai shareholders to provide three months of personal bank statements demonstrating genuine capital adequate for their share subscription. Registrars now request evidence of fund transfers and source-of-funds documentation as standard practice, not as an exception triggered by suspicion.
Why This Puts Pressure on Existing Structures
Companies set up years ago under the simpler 49% threshold may not have documented their Thai shareholders’ financial capacity in a way that satisfies current scrutiny.
| Structure element | What regulators now examine |
| Shareholding | Still checked, but no longer sufficient alone |
| Board composition | Who actually controls decisions |
| Financing | Whether Thai shareholders’ capital is genuine |
| Voting arrangements | Whether Thai shareholders have real voting power |
Industry commentary expects enforcement to intensify through 2026 and into 2027, with the Department of Business Development using banking data, director-change filings, and beneficial-ownership registers to identify arrangements that look like nominee shareholding on closer inspection.
What This Means for Accounting Support
This isn’t purely a legal compliance issue. It touches directly on how a company’s books, capital records, and financial documentation get maintained.
- Bank statement and capital contribution records for Thai shareholders now need to be gathered and retained ahead of time, not assembled only when a registrar asks
- Annual financial statements and the underlying bookkeeping need to reflect a structure that would hold up to the “actual control” examination, not just the shareholding percentage on paper
- Companies with structures set up under the older, simpler rules benefit from a review now, before a routine filing triggers closer scrutiny than expected
The Legitimate Paths Forward Haven’t Disappeared
None of this closes off foreign business ownership in Thailand. BOI promotion, a Foreign Business Licence, and treaty-based routes like the US-Thailand Treaty of Amity remain available for genuine majority or full foreign ownership, each with its own approval process and timeline.
Working with an accounting firm in Thailand that understands how these 2026 changes intersect with day-to-day bookkeeping and capital documentation matters more now than it did even two years ago. A structure that was compliant on paper in 2023 isn’t automatically compliant under a regulatory framework built around examining actual control rather than a static shareholding percentage.
What a Structure Review Actually Involves
For companies incorporated before the 2026 reforms, understanding current exposure starts with a systematic look at how the business actually operates, not just what the constitutional documents say on paper.
Questions Worth Answering Now
- Do the Thai shareholders on record have documented, verifiable capital behind their shareholding, or does the paper trail have gaps?
- Does actual board voting power reflect the shareholding percentages, or do side agreements and management arrangements shift real control elsewhere?
- Are loan arrangements between the company and its foreign stakeholders structured in a way that could itself be read as a control indicator?
Why Waiting Isn’t a Neutral Choice
A company that does nothing isn’t preserving the status quo. Enforcement tools are actively expanding, and a routine annual filing or licence renewal is exactly the kind of touchpoint where a registrar applying the new scrutiny standard might flag a structure that previously went unexamined. Addressing gaps before they surface during a routine process generally produces a much smoother outcome than responding after a regulator has already raised concerns.
The Cost of Getting This Wrong
Structures found to rely on nominee shareholding arrangements without genuine commercial basis face serious consequences under Section 36 of the Foreign Business Act, including criminal liability for directors and potential forced dissolution of the company. This isn’t a minor compliance footnote. It’s the sharpest edge of the 2026 reforms, and it’s exactly why the accounting and documentation side of a company’s structure now carries legal weight it didn’t carry as directly before this year.
