Thailand BOI introduces quarterly progress reporting for promoted companies.
Thailand’s Board of Investment (BOI) has tightened its post-approval compliance framework for promoted companies, replacing the longstanding semi-annual reporting requirement with a new quarterly system. The change, effective since 30 March 2026, means companies in the implementation phase of a BOI-promoted project must report progress four times a year rather than twice.
With the first deadline falling on 31 May 2026, promoted companies should act now to understand what is required and ensure their internal processes are ready.
What has changed and why it matters
The new regime is introduced through two complementary instruments: BOI Announcement No. 8/2569 dated 30 March 2026, which establishes the substantive quarterly reporting obligation, and BOI Office Announcement No. Por. 5/2569 dated 20 April 2026, which sets out the submission procedures via the BOI e-Monitoring system.
The requirement applies during the implementation phase of a promoted project, from issuance of the promotion certificate until the BOI operating licence is granted, after which it no longer applies.
The BOI derives its authority from Section 20 of the Investment Promotion Act, which empowers the Board to set conditions on promoted companies covering operational, financial and regulatory matters, including project progress reporting.
The new reporting schedule
Progress reports must be submitted within 60 days of the end of each calendar quarter through the BOI e-Monitoring portal. The deadlines are as follows:
| Reporting period | Period covered | Submission deadline |
|---|---|---|
| Q1 | 1 January – 31 March | 31 May |
| Q2 | 1 April – 30 June | 31 August |
| Q3 | 1 July – 30 September | 30 November |
| Q4 | 1 October – 31 December | 28 February (following year) |
Companies that receive their promotion certificate during a quarter are not required to file for that quarter. Their first reporting obligation begins in the following quarter.
A tighter timeline for penalties
The BOI’s enforcement framework remains unchanged, but the consequences of non-compliance now arise much faster. Missing a single quarterly deadline may result in the suspension of BOI rights and benefits, including the processing of visa and work permit applications for foreign employees.
Missing two consecutive deadlines without valid justification may lead to permanent revocation of BOI promotion, along with the corporate income tax exemptions, import duty privileges and other incentives that come with it.
Under the previous semi-annual schedule, reaching the two-consecutive-failure threshold took a full year. Under the new quarterly system, the same threshold can be reached in six months, significantly reducing the margin for error.
What promoted companies should do now
The shift to quarterly reporting represents a structural change in how the BOI monitors investment progress, meaning reporting should be built into regular operational and finance cycles rather than treated as a periodic task.
Companies should review whether their internal workflows are aligned with the new quarterly cycle, confirm that their e-Monitoring access is up to date, and assign clear responsibility for report preparation and submission. Where third-party advisers manage BOI filings, early coordination ahead of each deadline is advisable.
