Foreign ownership adds a layer of complexity to opening business banking in Thailand that Thai-owned SMEs simply don't encounter — and the rules aren't always intuitive to someone setting up a business in Thailand for the first time.
Thailand's Foreign Business Act restricts certain business activities for foreign-majority-owned companies, and your ownership structure directly affects which banking relationships are realistically available to you. A majority-Thai-owned company generally faces fewer hurdles than a majority-foreign-owned one, all else being equal.
For businesses in BOI-eligible activities, BOI promotion can meaningfully expand foreign ownership allowances and, in many cases, make banking easier — since a BOI certificate signals to a bank that your business plan, financials, and (for tech companies) technology stack have already been reviewed by a government body.
Beyond the standard company registration documents, expect requests for work permits for foreign directors, clearer beneficial ownership disclosure, and sometimes a more detailed explanation of the source of the founder's initial capital. This isn't unique to Thailand — most jurisdictions apply more scrutiny to foreign-owned entities — but it does mean foreign founders should budget more time for the process than a Thai-owned SME might need.
A traditional bank's foreign-ownership scrutiny process can be lengthy and, at smaller Thai branches, inconsistently applied. A licensed payment infrastructure provider that already operates across multiple regulated jurisdictions — rather than a single domestic branch network — is often better equipped to assess a foreign-owned business efficiently, because handling cross-border ownership structures is closer to its core business than it is for a traditional retail bank.
Foreign-owned SMEs should expect banking setup to take longer than the headline numbers often quoted for Thai-owned companies — plan for this rather than being caught off guard by it partway through the process.
