Thailand has launched one of its largest nationwide investigations into suspected foreign “nominee” business structures, targeting companies believed to be illegally controlled by foreigners through Thai proxy shareholders.
Authorities say the operation is no longer limited to isolated investigations. The crackdown has now expanded across major tourism and investment destinations including Pattaya, Phuket, Koh Samui, Koh Phangan, and Hua Hin, as officials move aggressively to dismantle what they describe as illegal foreign business networks operating under Thai names.
According to the Department of Business Development (DBD), investigators are now examining more than 50,000 companies suspected of using Thai nationals as nominee shareholders to bypass restrictions under Thailand’s Foreign Business Act.
What Is a “Nominee Business”?
Under Thai law, foreigners are restricted from fully owning certain types of businesses, particularly in sectors considered sensitive to the local economy such as tourism, hospitality, real estate services, restaurants, retail, and land-related activities.
To circumvent these restrictions, some foreign operators allegedly use Thai nationals to hold shares on paper while the foreigner maintains actual control of the company. This practice is commonly known as a “nominee structure.”
Thai authorities stress that simply having 51% Thai ownership on documents is no longer enough to prove legal compliance. Regulators are now investigating who truly controls the company, who provided the investment funds, who signs contracts, and who receives the financial benefits.
Tourist Islands Under Heavy Investigation
The government’s recent investigations began intensifying on the islands of Koh Samui and Koh Phangan after authorities discovered unusually high levels of foreign-linked businesses operating in the tourism sector.
Officials revealed that nearly 68% of registered companies on the two islands involved foreign joint investment structures, raising concerns over widespread nominee arrangements.
In one case currently under investigation, authorities examined luxury beachfront villa operations allegedly linked to foreign investors using Thai nominees. Investigators traced land leases, company structures, and financial transactions that may indicate foreign control hidden behind Thai shareholders.
Authorities also uncovered situations where a single Thai individual allegedly appeared as a shareholder in dozens of separate companies — a major red flag commonly associated with nominee arrangements.
Pattaya and Phuket Also Targeted
The operation has now expanded well beyond the islands.
Authorities recently confirmed that investigations are actively underway in Pattaya and Phuket, where officials suspect illegal foreign ownership structures in tourism businesses, property ventures, restaurants, entertainment venues, and tour operations.
Earlier this year, multiple tour companies in Pattaya reportedly had their licenses revoked following investigations into illegal nominee operations.
Government agencies involved in the crackdown now include:
Department of Business Development (DBD)
Royal Thai Police
Anti-Money Laundering Office (AMLO)
Tourist Police
Immigration Bureau
Provincial authorities
Officials say the investigations are not limited to corporate registrations alone. Authorities are also examining:
tax records,
work permit violations,
tourism licenses,
suspicious land ownership,
and financial transactions connected to foreign business operators.
Stricter Rules for Company Registration
As part of the crackdown, Thailand is introducing stricter registration procedures for companies involving foreign participation.
Under the new measures, Thai shareholders in certain businesses may now be required to provide bank statements and financial evidence proving that they genuinely invested their own funds into the company.
Authorities say the goal is to eliminate “paper shareholders” who exist only to help foreigners bypass ownership restrictions.
The Ministry of Commerce has described nominee businesses as harmful to Thailand’s economic structure because they create unfair competition against legitimate Thai entrepreneurs.
Serious Criminal Penalties
Under Thailand’s Foreign Business Act, both the foreign operator and Thai nominees may face severe legal consequences if found guilty.
Potential penalties include:
imprisonment of up to three years,
fines up to 1 million baht,
revocation of business licenses,
company dissolution,
deportation for foreign nationals,
and possible asset seizure or money laundering investigations.
Authorities have also warned that law firms, accountants, and consultants who knowingly assist illegal nominee arrangements could face investigation as well.
Impact on Foreign Investors and Expats
The crackdown has created growing concern among foreign business owners, investors, and long-term residents throughout Thailand.
Many legal experts say the government is attempting to distinguish between:
legitimate foreign investment structures,
and illegal proxy ownership arrangements designed to conceal foreign control.
Industry observers believe Thailand still welcomes foreign investment, particularly through lawful structures such as:
BOI promotion,
Foreign Business Licenses,
Treaty of Amity companies,
and fully compliant joint ventures with genuine Thai participation.
However, the message from authorities is becoming increasingly clear:
Thailand is entering a new era of stricter enforcement, especially in tourism-heavy provinces where foreign influence over local businesses has expanded rapidly in recent years.
A Turning Point for Foreign Businesses in Thailand?
The nationwide crackdown signals what may become a major shift in Thailand’s approach toward foreign-controlled businesses.
With investigations expanding and financial scrutiny increasing, authorities appear determined to close long-standing loopholes that previously allowed questionable nominee structures to operate with minimal oversight.
For foreign investors and business owners operating in Thailand, legal compliance is no longer simply about paperwork — regulators are now focusing on the true substance and control behind each company.
As investigations continue across the country, the coming months could reshape the landscape for foreign-owned and foreign-linked businesses throughout Thailand’s tourism and property sectors.
