Direct answer

A foreigner can establish or invest in a Thai business only through a structure lawful for the exact activity and facts. Define the business first, then obtain advice on foreign ownership restrictions, licences, BOI promotion if eligible, entity and capital needs, tax, employment and immigration, banking, contracts, and premises. Registering a company alone does not authorise a restricted activity, work, or land ownership.

Key takeaways

  1. 1.The business activity determines the legal route.
  2. 2.Company registration, activity permission, work authority, and land rights are separate.
  3. 3.Thai shareholders must be genuine investors, never nominees.
  4. 4.BOI promotion is conditional and is not available merely because a foreigner forms a company.

Important terms

Business activity is what the company actually sells or does. Legal screening should use specific revenue-generating activities, not a broad label.

Foreign ownership review determines whether the proposed ownership and control are permitted for those activities and whether approval, promotion, or another route is required.

BOI promotion is conditional approval for an eligible promoted project. It is not automatic company registration. (boi-setup)

Nominee shareholder is a person who merely lends a name or holds shares for another to disguise the true ownership arrangement. Thai Realty Guide does not present nominees as lawful compliance.

Detailed answer

Start with a two-page operating plan: products or services, customers, where work occurs, contracts, money flows, assets, staffing, technology, imports or exports, regulated touchpoints, and property needs. The legal route cannot be selected reliably until those facts are clear.

Next, obtain a written activity and ownership analysis. It should identify which activities a foreign-owned enterprise can conduct, which need permission or promotion, and which licences come from sector regulators or local authorities. Do not assume that incorporating through the Department of Business Development authorises every activity stated in broad company objectives. (dbd)

Assess BOI promotion only if the real project fits current promoted activities and conditions. Official BOI setup materials provide the starting point. (boi-setup) Build the application around genuine operations, investment, technology, staffing, and reporting obligations—not around a desire to own a residence.

Choose the entity, ownership, governance, capitalisation, directors, signing rules, shareholder arrangements, accounting year, and registered premises. Any Thai shareholder must be a genuine shareholder with real economic and governance substance. Side agreements that convert Thai shareholders into stand-ins create serious risk.

Create parallel implementation tracks:

  • Registration and licences: entity, tax, sector, premises, local and operational permissions.
  • Tax and accounting: bookkeeping, corporate income tax, VAT analysis, withholding obligations, invoices, payroll, and filings. Official Revenue Department pages are starting points. (rd-cit; rd-vat)
  • People and immigration: employment contracts, payroll, work authorisation, visas, and workplace compliance.
  • Banking and contracts: beneficial ownership, source of funds, authorities, customer and supplier terms.
  • Premises: lease or lawful property rights, permitted use, licences, and access.

BOI land procedures concern approved promoted operations and their conditions. (boi-land) They are not a condominium or holiday-home shortcut.

Step-by-step

  1. Describe actual activities and money flows.
  2. Screen foreign ownership and all licences.
  3. Test BOI eligibility against current promoted activities.
  4. Compare entity, branch, partnership, and contractual options with counsel.
  5. Design genuine ownership, governance, and capital.
  6. Register through the applicable official processes.
  7. Establish tax, accounting, payroll, and internal controls.
  8. Obtain operational, employment, and immigration approvals before acting.
  9. Secure lawful premises suited to approved use.
  10. Maintain filings, licences, BOI conditions, and corporate records.

RouteAppropriate questionIncorrect assumption
Thai company registrationIs this the right entity and properly registered?Registration permits every activity
Activity-specific permissionWhat restriction or regulator applies?Broad objectives remove restrictions
BOI promotionDoes the real project meet current conditions?Foreign ownership guarantees promotion
Genuine joint ventureDo parties truly invest, control, and share risk?Thai names can be borrowed
Premises leaseDoes the site support lawful operations?Leasing premises authorises the business

Hypothetical example

Hypothetical. A foreign founder plans software development plus regulated financial intermediation under one vague “consulting” description. Counsel separates the activities, finds that they require different analysis, and tests only the genuinely eligible technology project for BOI promotion. The founder registers the correct entity, obtains required permissions, and leases an office. The office and registration alone did not authorise the regulated activity.

Risks

  • Incorporating before screening actual activities
  • Using nominees to disguise control
  • Assuming BOI approval is automatic or permanent
  • Working before immigration and work authority are in place
  • Operating from premises not approved for the intended use
  • Missing tax, VAT, withholding, payroll, or accounting duties
  • Mixing personal property ownership with company operations
  • Using copied constitutional documents without governance protections

Checklist

  • Activity map completed
  • Foreign ownership analysis obtained
  • Sector and local licences identified
  • BOI eligibility tested honestly
  • Shareholders are genuine
  • Governance and signing authority documented
  • Tax and accounting systems established
  • Employment and immigration requirements satisfied
  • Banking and source-of-funds evidence prepared
  • Premises and land rights match real operations

FAQ

Can a foreigner own all of a Thai company?

The answer depends on the exact activities, structure, permissions, promotion, and other facts. Do not apply one ownership percentage to every business.

Does registering a company let the foreign founder work?

No automatic conclusion follows. Company registration and individual immigration or work authority are separate.

Do I need Thai shareholders?

That requires activity- and structure-specific advice. If Thai shareholders participate, they must be genuine; nominees are not a compliance strategy.

Can a BOI-promoted company own land?

Certain land procedures exist for approved promoted business purposes and conditions. They are not a personal residential workaround. (boi-land)
