Foreign Business Act Thailand 2026: 10 Restricted Businesses Proposed for Delisting

Thailand’s government has proposed one of the most significant regulatory changes for foreign investors in recent years — amending the Foreign Business Act (FBA) B.E. 2542 (1999) to remove ten business categories from its restricted lists. This landmark reform signals Thailand’s commitment to attracting greater foreign direct investment, supporting innovation-driven industries, and strengthening the country’s position as a competitive destination for international business in Southeast Asia. For foreign entrepreneurs, tech companies, and multinational corporations considering market entry or expansion in Thailand, understanding the scope and implications of this proposed amendment is essential for strategic planning in 2026 and beyond.

Background: How the Foreign Business Act Works

The Foreign Business Act has served as the principal legislation governing foreign participation in Thai business activities for more than twenty-five years. The law was designed to balance the need for international market access with the protection of domestic Thai operators from unrestricted foreign competition. Under the FBA, any individual, entity, or Thai-incorporated company with 50 per cent or more foreign shareholding is classified as a “foreign” business and is subject to specific restrictions depending on the type of activity.

Business activities are classified across three annexes. Annex 1 covers activities that are completely prohibited for foreigners, including newspaper publishing, radio and television broadcasting, and land trading. Annex 2 lists activities — such as domestic land transportation, antique trading, and salt farming — that require ministerial permission and cabinet approval before foreign participation is allowed. Annex 3 encompasses a broad range of retail, wholesale, and service businesses that require a foreign business license (FBL) issued by the Director-General of the Department of Business Development (DBD) under the Ministry of Commerce.

The FBA’s Annex 3 has long been considered the most impactful restriction for foreign investors because item 21 — “Other service businesses” — casts an exceptionally broad net, effectively requiring an FBL for virtually any service-related business not covered elsewhere. This has historically made Thailand’s foreign investment framework more restrictive than many of its regional competitors, a factor reflected in the country’s relatively high score on the OECD’s FDI Regulatory Restrictiveness Index.

The Proposed Amendment: 10 Business Categories to Be Delisted

Following the Thai Cabinet’s approval in principle on 22 April 2025, the Department of Business Development announced at its public seminar “Shaping the Future of Foreign Business Facilitation in Thailand” on 29 January 2026 that ten specific business activities are being considered for removal from the FBA’s restricted annexes. This means that once the amendment is enacted, foreign investors will be able to operate in these sectors without obtaining a foreign business license or partnering with a Thai majority shareholder.

The ten business activities proposed for delisting are:

1. Telecommunication services (Business Type 1) — This covers telecom service providers that do not own their own telecommunications network infrastructure. Delisting this category opens the door for foreign companies to provide telecom services in Thailand without FBA restrictions, aligning with the government’s digital economy objectives.

2. Treasury centre business under exchange control laws — Foreign-owned treasury centres managing cash pooling, intercompany lending, and foreign exchange activities for multinational groups will no longer require an FBL, making Thailand more attractive as a regional treasury hub.

3. Software development business — Widely regarded as the most significant delisting for the technology sector, this change allows foreign companies to establish fully owned software development operations in Thailand. This directly supports the government’s S-curve industries initiative and positions Thailand to compete with regional technology hubs.

4. Management services for affiliated or group companies — This covers administrative functions such as human resources management, IT services, and operational support provided within a corporate group. Foreign multinational companies will be able to centralise shared services in Thailand without FBA limitations.

5. Domestic credit guarantee business for affiliated or group companies — Foreign-owned entities providing credit guarantees within their corporate group will be exempt from FBA licensing requirements.

6. Leasing space for electronic financial service devices and vending machines — This niche category covers the placement and leasing of ATMs, payment terminals, and automated vending equipment in commercial locations.

7. Petroleum drilling service business — Foreign drilling service companies will be able to operate in Thailand’s oil and gas sector without FBA restrictions, potentially attracting greater international investment in energy exploration and production.

8. Lending business secured by collateral — This covers lending activities as permitted under securities and exchange legislation and derivatives law, enabling foreign financial institutions to expand their secured lending operations.

9. Services as agent, dealer, consultant, or fund manager for derivatives contracts — Specifically targeting derivatives whose underlying commodities or variables are not subject to the Derivatives Act B.E. 2546 (2003), this delisting opens Thailand’s financial services market to a broader range of foreign participants.

10. Domestic trade related to traditional agricultural products — Foreign companies will be able to trade in traditional agricultural commodities within Thailand’s domestic market, including participation in agricultural futures trading.

What This Means for Foreign Investors

The practical impact of these delistings is substantial. Once enacted, foreign investors operating in these ten sectors will no longer need to apply for a foreign business license from the DBD. This eliminates significant administrative burdens, reduces the typical approval timeline from up to 60 days to essentially zero for these specific activities, and removes the requirement to find a Thai majority shareholder or nominee partner.

For the technology sector, the delisting of software development is particularly transformative. Foreign SaaS companies, digital agencies, app developers, and IT service providers will be able to establish wholly foreign-owned subsidiaries in Thailand. Combined with existing Board of Investment (BOI) incentives — which can offer corporate tax rates as low as zero to eight per cent — Thailand becomes significantly more competitive compared to Singapore and Hong Kong for technology businesses seeking Southeast Asian operational bases.

Financial services firms also stand to benefit considerably. The delisting of treasury centre operations, derivatives services, collateralised lending, and credit guarantee activities creates new opportunities for foreign banks, asset managers, and financial advisory firms to expand their Thai operations without the FBA overhead.

Energy companies, particularly those in oil and gas exploration services, will find it easier to establish direct operations in Thailand’s petroleum sector. Similarly, agricultural commodity traders gain access to Thailand’s domestic agricultural market — one of the largest in Southeast Asia — without requiring an FBL.

Timeline and Implementation Status

The amendment process is currently in its consultation and drafting phase. Following the Cabinet’s in-principle approval on 22 April 2025, the DBD has been tasked with preparing the formal legislative amendments. The public seminar on 29 January 2026 served as a stakeholder consultation milestone, confirming the ten business categories under consideration.

The Commerce Ministry is now seeking full cabinet approval for the final amendment text. Based on Thailand’s recent track record with regulatory reform — including the swift implementation of BEPS tax measures in 2024 — a realistic timeline for enactment is mid to late 2026. However, the exact implementation date will depend on the cabinet approval process, parliamentary review (if required), and the preparation of subordinate regulations.

Foreign investors and their legal advisors should actively monitor developments from the DBD and the Ministry of Commerce. Early preparation — including reviewing corporate structures, assessing market opportunities, and preparing incorporation documents — will enable businesses to move quickly once the amendments take effect.

Context: Thailand’s Broader Investment Liberalisation Strategy

The proposed FBA amendment does not exist in isolation. It is part of a broader government strategy to reposition Thailand as a premier investment destination in the ASEAN region. The Ministry of Commerce has stated that the draft amendments focus on three core objectives: shifting the law’s purpose from merely protecting Thai businesses to building Thailand’s overall economic competitiveness; removing outdated restrictions that hinder sectors such as technology and startups; and revisiting strict foreign ownership limits, which have traditionally been capped at 49 per cent.

Thailand’s application for OECD membership in 2024 has also added urgency to investment liberalisation efforts. The OECD’s FDI Regulatory Restrictiveness Index, which evaluates 22 economic sectors across criteria including foreign equity limits and screening processes, places Thailand in a relatively unfavourable position compared to regional peers. Delisting these ten business categories is expected to improve Thailand’s score and strengthen its OECD membership candidacy.

Simultaneously, the Thai government has intensified enforcement against unlawful nominee shareholding arrangements. In April 2025, the Ministry of Commerce announced plans to inspect nearly 47,000 business entities suspected of using Thai nominees to circumvent FBA restrictions. Penalties for nominee arrangements include fines of up to THB 1 million and imprisonment of up to three years. A proposed amendment would also make FBA breaches predicate offences under the Anti-Money Laundering Act, enabling asset seizure. Foreign businesses currently operating through nominee structures should seek immediate legal advice to restructure their operations ahead of these enforcement measures.

Sectors That Remain Restricted Under the FBA

It is important to note that the proposed amendment covers only ten specific business categories. The vast majority of activities listed under Annexes 1, 2, and 3 of the FBA will remain restricted. Annex 1 activities — including media, broadcasting, and land trading — remain completely prohibited for foreign investors. Annex 2 activities still require ministerial and cabinet-level approval. The remaining Annex 3 activities, including general retail and wholesale trade, construction, and the broadly defined “other service businesses” category, will continue to require foreign business licenses.

Foreign investors looking to enter sectors outside the ten delisted categories will still need to navigate the existing FBA framework. Options include applying for a foreign business license, obtaining BOI promotion (which can exempt certain activities from FBA restrictions), establishing a joint venture with Thai partners, or structuring operations through a Treaty of Amity company for qualifying US nationals. Working with an experienced corporate law firm in Bangkok is essential for identifying the most effective legal structure for your specific business objectives.

How Foreign Businesses Should Prepare

For businesses looking to take advantage of the proposed delistings, early preparation is critical. There are several practical steps that foreign investors should consider taking now.

First, assess your business classification to determine whether your intended activities fall within one of the ten delisted categories. This requires careful analysis because the FBA’s business classifications can be narrowly defined, and operating outside the scope of your licence or exemption carries significant penalties.

Second, review your existing corporate structure. If you currently operate in Thailand through a joint venture, nominee arrangement, or BOI-promoted company specifically to comply with FBA restrictions in a soon-to-be-delisted sector, the amendment may create opportunities to restructure for full foreign ownership.

Third, prepare your incorporation documentation. Having corporate documents, powers of attorney, and memoranda of association ready in advance will enable you to move quickly when the amendments are enacted.

Fourth, evaluate complementary incentives. The FBA amendment can be combined with BOI investment promotion benefits, Eastern Economic Corridor (EEC) incentives, and Smart Visa programmes to maximise the advantages of establishing or expanding operations in Thailand.

Finally, engage qualified legal counsel. The interaction between the FBA, BOI regulations, tax laws, and sector-specific regulations creates a complex regulatory environment. An experienced business lawyer in Thailand can ensure your market entry strategy is both legally compliant and commercially optimised.
