Thailand’s Board of Investment (BOI) has significantly revised its post-approval compliance framework for projects that receive investment promotion incentives, replacing the previous semiannual reporting system for project progress with a new quarterly reporting regime. The initial report is due by July 30, 2026, covering the second-quarter reporting period of April to June 2026. The new requirements—implemented through BOI Announcement No. 8/2569 and Office of the BOI Notification No. Por. 8/2569, both of which became effective on March 30, 2026—apply both to newly promoted projects and to existing promoted projects that remain in the implementation stage. Background Under the previous reporting framework, BOI-promoted companies that had not yet commenced full operations were generally required to submit reports on project progress to the BOI twice a year (February and July) through the BOI’s e-Monitoring system. By adopting a quarterly reporting regime, the BOI seeks to strengthen monitoring and evaluation of investment progress and project implementation. Reporting Requirements Under the new regulations, BOI-promoted companies must submit project progress reports on a quarterly basis during the implementation phase of a promoted project. The reporting periods and submission deadlines are: Q1 (January–March): April 30 Q2 (April–June): July 30 Q3 (July–September): October 30 Q4 (October–December): January 30 of the following year The quarterly reporting obligation runs from the date the BOI promotion certificate is issued until the BOI grants approval for commencement of full operations. For newly promoted projects, no quarterly report is required for the quarter in which the BOI promotion certificate is issued—the first reporting obligation arises in the immediately following reporting period. All project progress reports must be submitted electronically through the BOI’s e-Monitoring system. The existing annual reporting requirement also remains in effect, requiring promoted companies to submit an annual operating results report through the e-Monitoring system by July 31 of

Tilleke & Gibbins has contributed the Cambodia, Myanmar, Thailand, and Vietnam chapters to Data Protection and Cybersecurity Regulation in Southeast Asia, a wide-ranging guide published by Drew Network Asia (DNA). The resource provides a comprehensive overview of data protection and cybersecurity laws across the region, offering practical insight into compliance requirements and regulatory developments affecting organizations that handle personal data or operate digital services in Southeast Asia. The guide begins with a regional overview, including the broader ASEAN context and cooperation initiatives. Jurisdiction-specific chapters follow a consistent structure—covering data privacy and governance obligations, security requirements and breach notification, outsourcing and cross-border data transfers, and broader accountability and compliance measures. This format allows readers to compare regulatory approaches across markets such as Brunei, Indonesia, Malaysia, the Philippines, Singapore, and others. In addition to the country chapters, the publication addresses cybersecurity and privacy engineering challenges, providing guidance for organizations and outlining obligations applicable to data controllers, processors, and intermediaries. A dedicated section on data breach management across ASEAN examines notification requirements, response considerations, and practical steps for managing incidents in a regional or global context. The guide is intended to serve as a practical reference, and the authors note that specific legal requirements may vary depending on sector, processing activity, or evolving legislation.
