The Department of Business Development and the Land Department are cross-checking about 125,600 companies under DBD supervision that hold land or condos, with tighter document rules for new firms since 1 August 2026. Most Thai SMEs are not affected, but companies with foreign shareholders (especially 0.01-49.99% foreign stakes) may face closer checks on registration, land holdings and BOI or industrial-estate status. If your company has foreign shareholders or nominee-style arrangements, review your shareholding and documentation now.
