What Changed on 1 August 2026
Order No. 2/2569 consolidates the rules that previously sat in two separate documents. Specifically, it repeals Order No. 2/2568 (dated 1 December 2025), which introduced the bank-statement requirement, and Order No. 1/2569 (dated 16 March 2026), which covered foreigners acting as authorised signatories. Now a single order governs both situations. In short, the Thailand company registration rules for 2026 apply whenever a foreigner invests or holds signing power.
The Department of Business Development (DBD) issued the measure to curb nominee arrangements, in which a Thai national holds shares on paper for a foreigner who supplies the real capital. Therefore, the DBD now demands documentary proof that each Thai shareholder genuinely funded their investment.
Who the 2026 Company Registration Rules Apply To
These 2026 company registration rules do not affect every company. Instead, it targets specific situations where a foreigner invests or holds signing power. The table below summarises the main triggers.
| Situation | What Triggers the Extra Documents |
|---|---|
| New company or partnership | A foreign partner or shareholder holds shares worth less than 50% of the registered capital. |
| New company (Thai shareholders only) | No foreigner holds shares, but a foreigner is a director with authority to sign and bind the company. |
| Amendment adding a foreign partner | A foreigner joins an existing entity and the combined foreign holding stays below 50%, with no foreign managing partner. |
| Amendment adding a foreign signatory | A previously all-Thai board changes so that a foreigner becomes an authorised signatory. |
| Existing entity amending within 1 year | A company registered before 1 August 2026 files a qualifying amendment within one year of its incorporation. |
The Documents You Must Now File
Under the order, the exact paperwork depends on whether you are registering a new entity or amending an existing one. In practice, two new forms carry the weight.
1. Investment Clarification Letter (for new registrations)
When you set up a new partnership or company, you must submit an Investment Clarification Letter (หนังสือชี้แจงการลงทุน) on the DBD template. Alongside it, you must attach bank statements that show the money actually moved. The order requires two views of the funds:
- A bank statement for each Thai partner or shareholder, covering the three months before payment, showing the withdrawal or transfer that funded their shares.
- A bank statement for the managing partner or director who received the funds, showing each incoming payment that matches the amounts and dates.
2. Investment Confirmation Letter (for amendments)
When you amend an entity to add a foreign partner or a foreign signatory, you must submit an Investment Confirmation Letter (หนังสือยืนยันการลงทุน). In it, the managing partner or directors confirm that every partner and shareholder genuinely invested, and that no Thai person is fronting for a foreigner. Crucially, the letter also acknowledges the criminal exposure for false statements.
Why the DBD Tightened the Rules
The 2026 company registration rules exist to stop nominee abuse. The government has pursued such structures aggressively throughout 2025 and 2026. These new documents give the registrar a practical tool. By comparing the outgoing payments from Thai shareholders with the incoming payments to the company, an official can quickly test whether the capital is real.
The stakes are high. The Investment Confirmation Letter expressly reminds signatories that a nominee arrangement breaches Section 36 of the Foreign Business Act B.E. 2542, which carries up to three years in prison and a fine of THB 100,000 to 1,000,000. Furthermore, giving false information to the registrar can trigger criminal liability under the Penal Code.
How the 2026 Company Registration Rules Affect Foreigners in Thailand
For most legitimate businesses, the order changes the paperwork rather than the fundamentals. Nevertheless, the practical impact is real, and early preparation matters. Consider the following points.
- Plan your funding trail. Thai shareholders should pay for shares from their own accounts, keep the transfers clean, and retain statements from the outset.
- Watch the timing. Because statements must cover the three months before payment, you cannot assemble them at the last minute.
- Mind the one-year rule. If you incorporated before 1 August 2026 and plan an amendment soon, the same proof requirements may apply.
- Review signatory structures. Appointing a foreign director with signing power now draws extra scrutiny, even where no foreigner holds shares.
Practical Steps to Stay Compliant
Foreign investors and their Thai partners can protect themselves with a disciplined approach to company registration in Thailand. We recommend the following:
- Map every shareholder’s funding source before you file.
- Ensure each Thai shareholder transfers their own funds, not money routed from a foreign party.
- Collect bank statements early and reconcile outgoing and incoming amounts.
- Prepare the Investment Clarification or Confirmation Letter on the correct DBD template.
- Take advice before appointing a foreign authorised signatory or restructuring ownership.
