Following our previous Thailand Board of Investment (“BOI”) alert[1], the BOI has issued BOI Annoucement No. Por.8/2569 dated 20 May 2026 (“BOI Annoucement No. Por.8/2569”)[2], which repeals the BOI Annoucement No. Por.5/2569 dated 20 April 2026 (“BOI Annoucement No. Por.5/2569”).

The new announcement revises the filing timeline for BOI progress reports. BOI-promoted companies must now submit progress reports quarterly, from the date the BOI promotion certificate is issued until the project receives approval for official commencement of operations. Importantly, the submission deadline has been shortened from within 60 days after quarter-end to within 30 days after quarter-end.

Accordingly, the progress reports must be submitted within 30 days from the end of each quarter, as outlined below.

For promoted projects approved during a quarter, the first progress report must be submitted in the following reporting quarter.

Non-compliance with this requirement may result in the suspension of the incentives and privileges granted under the promotion certificate. Furthermore, failure to submit progress reports for two consecutive periods may lead to the revocation of such incentives and privileges[3].

Who Is Impacted by These Updates

All BOI-promoted companies whose projects have not yet been granted approval for the official commencement of operations will be subject to this new requirement.

Companies should ensure timely compliance with the revised progress report submission timeline to mitigate the risk of non-compliance, including the potential suspension or revocation of incentives and privileges.
