Can Foreigners Own a Thai Company?

Under the Foreign Business Act, foreigners are generally limited to 49% ownership of a Thai company — unless you use a BOI promotion, a Foreign Business License, or (for US citizens) the Treaty of Amity, which allow majority or 100% foreign ownership. We advise on the right structure and register it end to end.

Structures We Set Up

  • Thai Limited Company (most common; foreign ownership up to 49%, or higher with BOI/FBL)
  • BOI-promoted company (up to 100% foreign ownership + work-permit and tax privileges)
  • Treaty of Amity company (US nationals; majority/100% ownership)
  • Branch / Representative Office

Work-Permit-Ready

We structure your company so it can sponsor a Non-B visa and work permit — including the standard requirements around registered capital and Thai-to-foreign employee ratios.

Frequently Asked Questions

Can a foreigner own 100% of a Thai company?

Generally no under the Foreign Business Act (49% cap), but yes with a BOI promotion, a Foreign Business License, or the US Treaty of Amity.

How much capital do I need?

A company sponsoring a work permit generally needs THB 2 million registered capital per work permit (waived/reduced under BOI).
