Q1051. How to translate BOI investment promotion documents into multiple languages?

Answered by the NYC Visa & Translation certified translation team

BOI investment promotion documents move in both directions. Thai-to-foreign: the BOI promotion certificate, its conditions schedule, and the approval letter are translated into English for the foreign parent, auditors, or banks — the certificate's promoted activity code, the conditions (local content, export ratios, machinery lists), and the tax privileges (corporate income tax holiday years, duty exemptions) must be rendered exactly, because the parent's compliance team manages against those conditions. Foreign-to-Thai: the applicant's corporate documents, financial statements, and technology descriptions are translated into Thai for the BOI application. Process notes: BOI applications are filed through the e-investment system, and the document formats are prescribed — translations should follow the BOI's own English terminology for activity categories (check the BOI's published English announcements); the feasibility study and project summary are the substantive documents and deserve careful translation since BOI officers assess on them; and post-approval, the annual compliance reports may need translation for the parent. Timing: certificate translation on a timeline confirmed after document review; a full application document set 1–3 weeks depending on volume. The BOI publishes current requirements at boi.go.th — confirm the applicable announcement for the specific activity before preparing the document set.
