Thailand Foreign Business Act 2026: What Foreign Investors Need to Know (DBD Order No. 1/2569 Explained)

The Thailand Foreign Business Act 2026 reforms represent the most significant tightening of foreign ownership rules in Thailand in over two decades. Anchored by DBD Order No. 1/2569, the changes introduce an “actual control” test that supplements the traditional 50-percent shareholding threshold, expanding the circumstances under which a company can be classified as foreign-controlled. For general counsel, CFOs and foreign investors managing or planning Thai operations, the practical effect is immediate: ownership structures, board arrangements, voting agreements and nominee relationships that were tolerated, or at least unexamined, before 2026 now carry materially higher compliance and enforcement risk. This guide explains what changed, what it means for your corporate structure, and the concrete steps you should take now.

Executive Summary, What Inbound Investors Need to Know

The 2026 reforms do not abolish foreign investment in Thailand. They do, however, redefine how “foreign” is determined and dramatically increase the penalties for non-compliance, particularly for nominee arrangements. The Department of Business Development (DBD) has issued Order No. 1/2569, which directs registrars and enforcement officials to look beyond formal share registers and assess whether foreign nationals exercise actual control over a Thai-registered entity.

For existing investors, this means that structures designed to keep foreign shareholding below 50 percent may no longer be sufficient if governance, management or financing arrangements indicate foreign control. For new investors, it means that structuring advice obtained before the reforms should be revisited before closing any transaction.

Industry observers expect that enforcement will intensify throughout 2026 and into 2027, with the DBD using enhanced cross-verification tools, including banking data, director-change filings and beneficial-ownership registers, to identify arrangements that may constitute nominee shareholding.

Immediate actions for foreign investors:

• Audit existing structures. Review all Thai entities for actual-control indicators: board composition, veto rights, management agreements, loan arrangements and voting protocols.
• Assess nominee exposure. Identify any Thai shareholders whose investment lacks a genuine commercial basis and document the rationale for all shareholding arrangements.
• Review governance documents. Ensure articles of association, shareholder agreements and board mandates do not grant foreign parties control beyond their formal shareholding percentage.
• Evaluate FBL or BOI pathways. Determine whether a Foreign Business Licence or Board of Investment promotion is the appropriate compliance route for each restricted activity.
• Engage Thai counsel. Obtain advice specific to your sector, ownership structure and operational footprint before the transitional window closes.
• Document compliance. Maintain a written compliance file that records the commercial rationale for each Thai shareholder, the independence of Thai directors and the absence of undisclosed side agreements.

Background: The Foreign Business Act, How We Got Here

Thailand’s Foreign Business Act B.E. 2542 (1999) has governed foreign participation in Thai business activities for more than 25 years. The statute divides restricted activities into three lists, List One (media, farming), List Two (activities affecting national security or the environment) and List Three (activities in which Thai nationals are not yet ready to compete), and prohibits foreigners from operating in those sectors without a Foreign Business Licence or an applicable exemption.

Under the original framework, the definition of a “foreigner” was anchored almost entirely to a 50-percent shareholding test: if foreign nationals or entities held 50 percent or more of a Thai company’s shares, the company was classified as foreign for FBA purposes. This relatively bright-line test gave rise to a well-known structuring practice. Foreign investors would arrange for Thai individuals, sometimes with little or no genuine economic interest, to hold a bare majority of shares, keeping the foreign stake just below 50 percent and thereby avoiding the need for a licence.

Enforcement against these nominee arrangements in Thailand was inconsistent. While the FBA contained provisions criminalising nominee shareholding, detection depended on manual review and complaints. The DBD lacked systematic tools to cross-reference shareholding records with financial data. The result was a compliance landscape in which the letter of the law was strict but practical enforcement was uneven, a dynamic that the 2026 reforms are explicitly designed to correct.

What Changed in 2026, DBD Order No. 1/2569 and Related Reforms

The 2026 overhaul of foreign ownership rules in Thailand centres on DBD Order No. 1/2569, a directive issued by the Department of Business Development that recalibrates how registrars, inspectors and enforcement officials assess whether a company is foreign-controlled. The Order does not amend the FBA statute itself; rather, it provides the interpretive and procedural framework through which the existing statute is now applied. The Thai government has simultaneously signalled broader legislative reforms to the FBA, though the Order represents the most concrete and immediately operative change.

Scope and Applicability

DBD Order No. 1/2569 applies to all companies registered with the DBD that have any level of foreign shareholding or foreign involvement in management. Its provisions are not limited to companies operating in List One, Two or Three activities, the Order instructs registrars to flag potential foreign-control indicators at the point of registration, annual filing and any corporate change (such as director appointments or share transfers). The Order also applies to partnerships and branches of foreign corporations.

Key provisions of the Order include:

• Expanded definition of control. Registrars must assess whether foreign parties exercise control through management authority, board composition, voting agreements, veto rights, loan conditions or operational decision-making, not only through shareholding percentages.
• Cross-verification obligations. The DBD is empowered to cross-reference corporate filings with banking records, tax data and director-change histories to detect patterns consistent with nominee shareholding.
• Enhanced disclosure requirements. Companies must provide additional beneficial-ownership information at the point of registration and during annual filings, including details of any shareholders who are related parties or who lack demonstrable financial capacity to have made their capital contributions.
• Referral and penalty escalation. Where indicators of nominee arrangements are detected, registrars are instructed to refer cases to the enforcement division. Administrative and criminal penalties, including fines and imprisonment, may follow.

Effective Date and Transitional Rules

The Order has been published and is operative. Companies with existing structures that may fall within the new actual-control analysis are expected to review and, where necessary, adjust their arrangements within the transitional window signalled in the DBD guidance. Early indications suggest that the DBD will prioritise sectors with historically high nominee activity, particularly real estate, retail and services.

Who Is a “Foreigner” Now? The 50% Share Test vs the Actual Control Test

The Thailand Foreign Business Act 2026 regime retains the 50-percent shareholding test as a baseline: any company in which foreign nationals or foreign-controlled entities hold half or more of the registered shares is classified as foreign. What has changed is that this is no longer the only, or even the primary, lens through which enforcement operates. The actual control test in Thailand now functions as a parallel assessment, capable of reclassifying a company as foreign-controlled even where formal foreign shareholding sits well below 50 percent.

The practical implications are significant. A company with 49-percent foreign ownership and 51-percent Thai ownership could still be treated as foreign if the foreign shareholder controls the board, holds veto rights over material decisions, provides the majority of the company’s financing, or dictates operational strategy through management or consulting agreements.

Examples of “Actual Control”

The following indicators, individually or in combination, may cause a company to be treated as foreign-controlled under the new framework:

• Board composition. A majority of directors are foreign nationals, or foreign-appointed directors hold casting votes or chair positions.
• Veto rights. Foreign shareholders hold contractual or constitutional veto rights over material business decisions, including budgets, asset disposals, key hires or strategy changes.
• Management control. Day-to-day operations are managed by foreign nationals under management agreements, secondment arrangements or consulting contracts that effectively subordinate Thai management.
• Financial dependency. The company is funded primarily by shareholder loans, intercompany financing or guarantees from the foreign party, giving that party economic leverage disproportionate to its shareholding.
• Voting agreements. Side agreements or powers of attorney that concentrate voting power in the hands of foreign parties, regardless of the share register.

The likely practical effect of this dual-test regime is that investors can no longer rely on share-register engineering alone. Every element of governance, from articles of association to shareholder agreements, board mandates and financing terms, must be reviewed for actual-control indicators.

Nominee Arrangements and Enforcement Risk, Red Flags and Due Diligence

Nominee arrangements in Thailand have long been the most contentious aspect of FBA compliance. A nominee arrangement exists where a Thai national holds shares on behalf of, or at the direction of, a foreign party, without a genuine independent economic interest in those shares. Under the FBA, both the foreign party procuring the arrangement and the Thai nominee can face criminal liability, including imprisonment and fines.

The 2026 reforms significantly increase enforcement risk. The DBD’s enhanced cross-verification powers mean that patterns previously difficult to detect, such as Thai shareholders who lack the financial capacity to fund their capital contributions, or directors who change simultaneously with changes in the foreign shareholder, are now flagged systematically.

How Authorities Detect Nominees

Under the new regime, enforcement officials apply a range of detection methods:

• Financial capacity checks. Comparison of a Thai shareholder’s declared income or assets against their capital contribution. Where the shareholder cannot demonstrate sufficient means, the arrangement is flagged for investigation.
• Banking cross-references. Analysis of capital-injection flows to determine whether funds originated from or were routed through the foreign party.
• Director and shareholder correlation. Patterns where Thai directors and shareholders are replaced simultaneously with changes in the foreign investor’s identity or interests.
• Beneficial-ownership disclosures. New annual filing requirements that compel companies to identify the ultimate beneficial owners of shares, including any trust, agency or nominee relationships.
• Complaints and whistleblowers. The DBD continues to act on complaints from business competitors, former employees and disgruntled partners, now with more effective investigative tools.

Practical Due Diligence Checklist for Nominee Risk

For investors conducting acquisitions, joint ventures or annual compliance reviews, the following checklist addresses the most critical nominee-risk indicators:

• Verify that every Thai shareholder can demonstrate independent financial capacity to have funded their capital contribution.
• Confirm that Thai directors have genuine management authority and are not merely signatories directed by the foreign party.
• Review all shareholder agreements, side letters and powers of attorney for undisclosed control provisions favouring the foreign party.
• Examine the company’s financing structure for disproportionate shareholder loans or guarantees from the foreign investor.
• Check the historical pattern of director and shareholder changes for correlation with changes in the foreign investor group.
• Ensure that board minutes reflect genuine deliberation and independent Thai-director participation, not rubber-stamping.
• Maintain a written compliance file documenting the commercial rationale for each Thai shareholder’s participation.

Foreign Business Licence Changes and Application Practicalities

For companies that cannot avoid FBA classification through BOI promotion or structural adjustments, the foreign business licence in Thailand remains the primary compliance pathway. The 2026 reforms have brought changes to both the application process and the evidentiary standards required for approval.

The DBD has signalled an intent to streamline FBL processing for certain List Three activities, with the likely practical effect being shorter approval timelines for applications that are complete, well-documented and supported by a clear business rationale. At the same time, scrutiny of the applicant’s ownership structure, management arrangements and capital sourcing has intensified, applications that raise actual-control concerns will face additional questions and possible delays.

Documents to Attach

• Completed FBL application form (DBD prescribed format)
• Certified copy of the company’s affidavit, articles of association and shareholder register
• Business plan describing the proposed activities, projected revenue and employment of Thai nationals
• Evidence of minimum capital (as required for the relevant FBA list category)
• Identification and background documents for all directors and shareholders, including beneficial-ownership disclosures
• Details of any management agreements, voting arrangements or financing structures involving foreign parties
• Tax identification and, where applicable, BOI correspondence confirming non-eligibility for promotion

Common Rejection Grounds

• Incomplete beneficial-ownership information. Failure to disclose the ultimate owners of shares or the existence of nominee, trust or agency relationships.
• Insufficient minimum capital. The registered and paid-up capital does not meet the threshold for the relevant FBA list category.
• Unclear business rationale. The business plan does not adequately demonstrate the economic benefit or the need for foreign expertise in the proposed activity.
• Actual-control red flags. Governance arrangements that suggest the Thai entity is, in substance, foreign-controlled, triggering additional review and possible referral.

BOI Incentives and Structuring Options in 2026

Thailand’s Board of Investment (BOI) continues to offer one of the most powerful alternatives to FBA licensing. Under the Investment Promotion Act, BOI-promoted companies may be permitted to operate in otherwise restricted sectors with majority or even 100% foreign-owned company Thailand structures, depending on the activity category and the incentive package granted. BOI incentives in 2026 include corporate income tax exemptions, import duty reductions, land-ownership rights and work-permit facilitation.

The interaction between BOI promotion and the new FBA/DBD regime is critical. A valid BOI promotion certificate can override FBA restrictions for the promoted activity, meaning that a company engaged solely in a BOI-promoted activity may not need a separate FBL. However, if the company also conducts non-promoted activities that fall under the FBA lists, those activities remain subject to the standard FBA analysis, including the new actual-control test.

Typical BOI-Friendly Structures

• Wholly foreign-owned subsidiary. For activities that qualify for BOI promotion under Category A or B, investors can operate through a 100% foreign-owned entity, avoiding the need for Thai shareholders entirely.
• Thai joint venture with BOI promotion. Where the activity requires local partnership or where BOI incentives are enhanced by Thai participation, a joint venture with genuine Thai partners, supported by clear governance and genuine economic contribution, can maximise both incentive eligibility and FBA compliance.
• Regional headquarters (IHQ/ITC). Thailand’s International Headquarters and International Trading Centre schemes offer tax and operational incentives for companies using Thailand as a regional base, with BOI promotion available for qualifying activities.

Hypothetical Structuring Example

Consider a foreign technology company seeking to provide software development services in Thailand. Software development is a List Three activity under the FBA. The company could apply for a BOI promotion under the digital economy category, which, if granted, would permit 100-percent foreign ownership and provide corporate tax incentives. If the company also plans to operate a retail showroom (a separate List Three activity not covered by the BOI promotion), it would need either a separate FBL for the retail activity or a restructuring that separates the two activities into distinct entities.

Restructuring Options and Practical Next Steps for Investors

Where the 2026 reforms expose an existing structure to actual-control risk or nominee vulnerability, investors face a practical decision tree:

1. Check BOI eligibility. Determine whether any or all of the company’s activities qualify for BOI promotion. If so, apply for promotion before restructuring ownership, this may resolve the FBA issue entirely for promoted activities.
2. Evaluate ownership options. If BOI is not available, assess whether the foreign shareholding can be genuinely reduced (through a real divestiture to an independent Thai partner) or whether the activity can be restructured to fall outside the FBA lists.
3. Separate management from voting rights. Review governance documents to ensure that Thai directors and shareholders exercise genuine authority and that foreign parties’ influence is proportionate to their shareholding. Remove or amend veto clauses, management agreements or loan covenants that create actual-control exposure.
4. Consider treaty-based options. Certain bilateral investment treaties and free trade agreements (such as the Thailand–Australia FTA) may provide additional market-access rights that modify FBA restrictions for qualifying investors. Treaty-based rights are investor- and activity-specific and require careful legal analysis.
5. Apply for an FBL. Where no other pathway is available, prepare a complete FBL application with enhanced documentation to address the new evidentiary requirements.

When to Seek a Formal FBL or BOI Approval

The decision between an FBL and BOI promotion is not always binary. Some investors will need both, a BOI promotion for the core promoted activity and an FBL for ancillary activities. The key is to map every revenue-generating activity against the FBA lists and BOI promotion categories before committing to a structure. Early engagement with qualified Thai counsel is essential to avoid costly mid-course corrections.

Compliance Checklist and Templates

The following checklists are designed for use by in-house legal teams and compliance officers managing Thai operations under the Thailand Foreign Business Act 2026 regime.

Pre-Investment Due Diligence Checklist:

• Map all proposed activities against FBA List One, Two and Three restrictions
• Confirm BOI promotion eligibility for each activity category
• Verify the financial capacity and commercial rationale of all proposed Thai shareholders
• Review all governance documents (articles of association, shareholder agreements, board mandates) for actual-control indicators
• Assess financing structure for disproportionate foreign-party leverage
• Obtain an FBA compliance opinion from qualified Thai counsel

Post-Investment Reporting Checklist:

• File annual beneficial-ownership disclosures with the DBD as required
• Maintain updated shareholder registers reflecting all transfers and changes
• Document board deliberations with minutes showing genuine Thai-director participation
• Report any material changes in shareholding, directors or management arrangements within the timeframes specified by DBD guidance
• Retain records of capital contributions, shareholder loans and intercompany financing for a minimum of five years

Nominee Risk Audit Checklist:

• Confirm that no Thai shareholder holds shares pursuant to an undisclosed agency, trust or nominee agreement
• Verify that all Thai shareholders’ capital contributions were funded from their own resources
• Check for side letters, call options or put options that would allow the foreign party to reclaim or control the Thai-held shares
• Review director-appointment history for correlation with foreign shareholder changes
• Ensure that no powers of attorney or proxy arrangements grant foreign parties voting control beyond their shareholding

Conclusion

The Thailand Foreign Business Act 2026 reforms mark a decisive shift from form-based to substance-based enforcement. The introduction of the actual-control test through DBD Order No. 1/2569 means that corporate structures, governance documents and financing arrangements, not just share registers, now determine whether a company is treated as foreign for FBA purposes. For inbound investors and companies already operating in Thailand, the message is clear: audit now, restructure where necessary, and document every element of your compliance position.

The reforms do not close the door to foreign investment in Thailand. They do, however, raise the compliance standard and eliminate the margin for ambiguous or nominee-dependent structures. Companies that proactively align their governance, ownership and licensing arrangements with the new framework will be well positioned to operate with confidence. Those that delay risk enforcement action, licence revocation and criminal exposure during a period of heightened regulatory scrutiny.
