Foreign Business License & BOI: What's Changed for Foreign Investors in Thailand

Setting up a foreign-owned company in Thailand almost always runs into the same question: does the business need a Foreign Business License (FBL) under the Foreign Business Act, or can it qualify for an exemption — most commonly through Board of Investment (BOI) promotion or a US-Thailand Treaty of Amity certificate (for US nationals)?

Recent procedural updates from the Department of Business Development (DBD) and the BOI have changed the practical experience of both routes.

Foreign Business License — what's changed

• Faster committee review cycles for FBL applications in service categories that are not considered sensitive (List 3 activities), with the DBD now publishing indicative review timelines on a rolling basis rather than a fixed annual schedule.
• Additional disclosure on ultimate beneficial ownership. Applicants must now provide a clearer ownership chart showing the ultimate individual beneficial owners behind any corporate shareholders — not just the immediate shareholding company.
• Capital verification at a later stage. Where an FBL is granted conditional on minimum capital (typically THB 2 million per business activity, or THB 3 million for FBL-licensed activities), the DBD has tightened the timeline for verifying that capital has actually been remitted into Thailand and recorded in the company's accounts.

BOI promotion — what's changed

• New and revised promoted activities. The BOI periodically updates its list of promoted business activities and the associated incentive categories (A1–A4, B1–B2). Several digital services, regional headquarters functions, and certain manufacturing-support activities have been reclassified with updated incentive packages — it's worth re-checking your activity's current category even if you reviewed it a year or two ago.
• Streamlined application for SME-scale projects. The BOI has simplified the application form and supporting-document checklist for smaller-scale projects (lower minimum investment thresholds), aimed at reducing the back-and-forth that used to extend approval timelines.
• Post-approval reporting. BOI-promoted companies now have clearer (and in some cases more frequent) reporting obligations on employment of Thai staff, machinery import usage, and investment milestones — failure to report on time can affect the renewal of related visa and work permit quotas.

Which route fits your business?

| Route | Best for | Key trade-off | |---|---|---| | FBL | Service businesses not eligible for BOI or Amity, where 100% foreign ownership is needed | Minimum capital requirements per activity; committee discretion on approval | | BOI promotion | Manufacturing, technology, regional service hubs, and activities on the current promoted list | Requires meeting the activity's specific investment/employment criteria; ongoing reporting | | US-Thailand Treaty of Amity | US-majority-owned companies in most sectors (excluding a short restricted list) | Only available to US nationals/companies; doesn't cover land ownership or a few restricted activities |

Practical takeaway

If your structure was set up more than a year or two ago, it's worth a short review: BOI activity categories shift, FBL ownership-disclosure expectations have tightened, and post-approval reporting obligations are easier to miss than the initial application requirements.
