FDI Approval in Thailand
Plan foreign direct investment in Thailand: activity-specific ownership rules, licences and certificates, structures, due diligence, funding, tax, approvals and exit.

Foreign direct investment in Thailand: structure and permission checks
Assess the actual activity before choosing ownership and structure. Compare ordinary, treaty and promotion routes, then review due diligence, liability, funding, tax and operating permissions. Foreign ownership, business permission and an investor’s personal right to live or work in Thailand are separate questions.
Find what you need
Use a section below to plan your next step.
Begin with the operation, not a headline ownership percentage
Foreign direct investment involves establishing or acquiring an interest in a business operation. The practical questions are what the Thai business will do, how it will be owned and funded, where it will operate and which permissions it needs. Portfolio securities, land purchases and personal immigration have different rules and should not be treated as the same decision.
Prepare a project description covering products, services, customers, contracts, people, sites and money flows. Compare a new operation, acquisition, branch and genuine joint venture against the same assumptions. A structure that works for manufacturing may not work unchanged for retail, services or a regulated industry.
Assess the Foreign Business Act and sector laws
The Foreign Business Act’s definition of a foreigner includes foreign entities and specified Thai entities with foreign capital participation. The Act restricts listed activities, and other sector laws can impose separate requirements. There is no single “foreigners may own only 49%” rule that answers every business question.
Have the actual activity, ownership and control assessed before signing binding commitments. Identify any licence, certificate or exemption, conditions and restrictions. A company’s registered objectives, tax number or bank account do not prove permission to perform every activity.
Use genuine funding and ownership records. Do not rely on nominal Thai shareholders to conceal the real arrangement. An agreement should reflect lawful ownership, decision rights and economic participation rather than a workaround described only in private side letters.
Compare ordinary, treaty and promotion routes
An ordinary foreign-business licence, a treaty-based certificate and a promotion-related certificate are distinct routes. Eligibility depends on nationality or ownership where relevant, the activity and the applicable conditions. A certificate under the Foreign Business Act is also distinct from the BOI promotion certificate itself.
For BOI, match the actual investment project to the current eligible activity and announcement. Promotion is conditional and does not remove every sector, site, employment or tax requirement. Do not include a tax holiday or unrestricted foreign ownership in the base case until the applicable approval and conditions support it.
Choose the entity with governance and liability in view
A Thai subsidiary is a separate locally incorporated company. A foreign branch remains part of its parent, with parent exposure. A representative office is for qualifying limited non-trading functions rather than a substitute for a sales operation.
For a joint venture, agree reserved decisions, board and signing powers, further funding, related-party dealings, information rights, profit distribution, deadlock and exit. Review enforceability and statutory formalities. A proposed percentage split does not by itself resolve who can act for the business or what happens when the partners disagree.
For an acquisition, test what you are actually buying
Confirm the seller, target entity, share ownership or assets, authority and transaction scope. Review contracts, licences, premises rights, staff, tax, accounts, debts, litigation, intellectual property and personal data. Ask which permissions can continue after the transaction and which require consent, notification or replacement.
Reconcile official filings with underlying records and current operations. Historical accounts and a DBD listing are useful starting points, not a guarantee that undisclosed liabilities do not exist. Use appropriate conditions, warranties, indemnities and completion evidence based on the findings.
Compare share and asset purchases with Thai and home-country advisers. They can leave different liabilities, tax costs, transfer steps and operational interruptions. Do not assume buying assets automatically transfers contracts, employees, permits or brand rights.
Document capital, loans and cross-border money
Agree the funding form and timing before remitting money: share investment, parent loan and payment for services are different transactions. Ask the authorised bank for the current supporting documents and reporting requirements. Retain remittance evidence, currency conversion records and the stated purpose.
BOT’s exchange-control framework allows investment inflows and repatriation within its rules, but this does not eliminate bank checks, documentation, tax or company-law requirements. Review dividends, interest, service fees, loan repayment and sale proceeds separately. Avoid treating “funds can be repatriated” as a promise of tax-free or unconditional withdrawal.
Model exchange-rate movements, working capital and a delayed launch. Legal minimum capital, a bank’s documentary requirements and the cash needed to operate are different measures. Obtain the actual calculation for the project rather than one generic investment threshold.
Build a tax and accounting model before completion
Review corporate income tax, VAT, withholding, customs, transfer pricing and treaty questions for the actual flows. Consider the investor’s home-country consequences alongside Thailand’s treatment. Offshore invoicing or a parent charge does not by itself settle where profit is taxable.
Arrange bookkeeping, audit, annual accounts and returns from the start. If incentives apply, establish the records needed to distinguish qualifying activities and support claims. Retain the evidence behind allocations and related-party transactions rather than creating it only when asked.
Make approvals and operating readiness part of the deal
List foreign-business, sector, product, site, environmental and employment approvals with their dependencies. Confirm which must be obtained before completion, payment, construction or trading. A long lease or equipment order should fit the realistic permission sequence.
Foreign owners, directors and staff need their own immigration and work review. Investment does not automatically create permission to reside or perform duties in Thailand. Agree the lawful start process and who will monitor each permission.
Plan changes, distributions and exit at the start
Document how further funding, dilution, share transfers, a sale, disagreement or closure will be handled. Check transfer restrictions, third-party consents, licence conditions, tax and the bank evidence needed to move proceeds. A shareholder agreement should work with the company’s constitutional documents and applicable law.
After investment, review the actual operation against the approved scope and initial assumptions. Assign owners for compliance, financial reporting and change control. Expansion, a new product or restructuring can change the permission analysis even when the investors remain the same.
Before committing investment funds
Common questions
Can a business be wholly foreign-owned?
Some can, subject to activity, sector laws and any applicable route and conditions. There is no universal percentage answer for every project.
Does BOI approval replace a Foreign Business Certificate?
They are different instruments. Where a promotion-related certificate is required, complete the relevant DBD process as well as BOI and other conditions.
Does investment guarantee a visa or work permission?
No. Individual immigration and work eligibility need separate assessment and approval.
Can I withdraw investment whenever I want?
Check company law, solvency, contracts, tax, bank documentation and exchange-control requirements for the actual transaction. Capital, dividends and loan repayments are not interchangeable.
