The Department of Business Development (DBD) and the Revenue Department have officially linked their databases to crack down on illegal foreign nominee businesses. This joint effort allows officials to cross-reference corporate filings with tax records to identify illegal ownership structures across five specific risk categories, according to Thai-language daily Khaosod.
The sweep is already producing concrete actions as part of a broader national crackdown. An AI-powered database analysis has targeted 33 suspected nominee firms, according to Travel And Tour World. Alongside this digital sweep, authorities are conducting physical raids. Officials recently raided luxury pool villas in Pattaya as part of a Chinese nominee probe, where laughing gas was also discovered, reports the Pattaya Mail. In Bangkok, authorities inspected two Chinese companies in a prominent Laksi mall after detecting abnormal financial trails, according to Khaosod.
What this means for you

If you operate a Thai limited company using the common 51% Thai and 49% foreign ownership structure, the regulatory environment is tightening. The Commerce Ministry is stepping up these efforts specifically to protect Thai businesses, and the integration of Revenue Department data means financial trails are easier to audit.
Here is what you need to monitor:
- Heightened data sharing: Authorities are no longer looking at corporate filings in isolation. They are actively matching DBD shareholder data with Revenue Department tax filings to spot financial inconsistencies.
- Historical context: While the headline numbers sound massive—Thaiger reports that Thailand recently flagged nearly 47,000 companies for potential issues—only 852 have faced formal charges so far.
- Investor vulnerability: As the Pattaya Mail notes, the 51-49 nominee model often leaves foreign investors as the real victims when structures are dissolved or challenged by authorities.
If you rely on a Thai company structure to hold property or operate a business, ensure your Thai partners are legitimate shareholders with verifiable sources of investment capital, rather than proxy names on paper.
