Thailand Investment Gateway
Build from an established business and industrial base, connect with ASEAN markets, and navigate the official pathways supporting investment, innovation and long-term growth.
Build in Thailand. Reach ASEAN. Grow Beyond Borders.
Thailand's investment proposition is not built on one advantage. It is the combination of location, industrial capability, infrastructure, supply chains, talent, market access and an established international business community.
One Strategic Base. Multiple Pathways to Growth.
Thailand connects businesses with ASEAN, China, India and global supply chains from the geographic center of mainland Southeast Asia.

Learn moreThere is no single route for every investor. The appropriate pathway depends on the business activity, ownership structure, investment value, location, technology, employment plan and eligibility for promotion.
For projects whose activities and conditions qualify under the current Thailand Board of Investment framework.
For businesses establishing under ordinary company, foreign-business, tax and sector-regulatory frameworks.
For eligible projects locating within the Eastern Economic Corridor and meeting current EEC conditions.
For operations considering Industrial Estate Authority of Thailand estates, special economic areas or another officially designated location.
These pathways may overlap. A project may involve company registration, BOI promotion, an EEC or industrial-estate location, sector licensing and immigration procedures at the same time.

Sector-Specific Licensing Systems
Digital licensing platforms operated by individual regulators (e.g. Thai FDA, TISI, DIW) for activity-specific approvals.
The Right Activity. The Right Structure. The Right Incentive Pathway.
The Board of Investment is Thailand's key official agency for supporting and evaluating foreign investment — covering tax incentives, non-tax incentives, investment facilitation, and defined eligible activities.
BOI does not promote every business. Eligibility depends on the exact promoted activity; conditions may include technology, value addition, process, investment amount, location, environmental requirements or other criteria. Approval is project-specific, incentive treatment is not automatic, and BOI promotion does not eliminate all licensing, tax, labour or regulatory obligations.
Eligibility and incentives depend on the specific activity and current official conditions. Confirm directly with BOI or the responsible authority.
Find investment guidance, consultation contacts, visa and work-permit facilitation, and the right official service for your next step.
BOI Help Desk & Single-Window Facilitation
A full T3 guide to TIESC, OSOS, the visa/work-permit Single Window and Customs NSW — who handles what, and how to prepare for a real conversation with the official desk.
Explore the guideEach area below covers a distinct part of BOI's promoted-activity framework — expand any category for its scope.
BOI promotes specific, listed activities across targeted industries (e.g. digital, EV, advanced manufacturing, BCG) — not every business qualifies, and eligibility is defined activity by activity.
Each application is evaluated as an individual project against the current criteria for its specific activity, not approved automatically.
Corporate income tax exemption periods vary by activity and merit — recent updates allow up to 8 years for qualifying digital, EV and green-energy projects; other activities may receive shorter periods or none.
Import duty exemption or reduction on qualifying machinery may be granted, depending on the promoted activity and project conditions.
Duty treatment on imported raw or essential materials used in production may be granted for export-oriented promoted projects.
Additional incentives may be available for projects that meet criteria such as R&D spending, workforce development, or technology transfer.
Projects located in designated investment-promotion zones, including second-tier provinces, may receive extended incentive periods.
Enhanced incentives exist for projects involving advanced technology, automation, or innovation-driven activity.
BOI promotion can facilitate majority or full foreign ownership for many promoted activities, subject to the specific activity's conditions.
Promoted companies may be granted rights to own land for the promoted business, subject to BOI approval and conditions.
BOI facilitates the entry of foreign specialists and executives needed for the promoted project.
BOI-promoted companies can access streamlined visa and work-permit processes through BOI's own service channels and TIESC.
Promoted companies must meet ongoing reporting, investment, and compliance conditions — promotion is not a one-time approval with no further obligations.
From Eligibility to Approval
BOI treatment depends on the promoted activity, the specific project's conditions, its location and BOI's current rules — it is not automatic for every business. Confirm eligibility for a specific activity directly with BOI before relying on any incentive.
Confirm the Exact Activity
Identify which BOI-eligible activity category, if any, matches the proposed business.
Review Current Eligibility and Conditions
Check the activity's current criteria, incentive tier and any location or technology conditions.
Prepare the Investment Project
Develop the project plan, investment value, technology, and workforce details required for the application.
Submit Through the Official BOI System
File the application through BOI's official channels.
Present or Clarify the Project Where Required
Respond to BOI's requests for clarification or presentation of the project.
Receive the Board's Decision
BOI evaluates and issues its decision on the application.
Accept Promotion
The applicant formally accepts the terms of the promotion, if granted.
Obtain the Promotion Certificate
BOI issues the certificate confirming the granted promotion and its conditions.
Complete Establishment and Operational Requirements
Finish company registration, capital, and operational steps tied to the promotion.
Maintain Reporting and Compliance
Meet BOI's ongoing reporting and condition-compliance requirements after promotion begins.
Potential incentives depend on the activity, project, location, investment structure and current approval conditions. The table is an orientation tool, not a promise of eligibility, and is not legal advice.

Turn an Investment Decision into an Operating Business.
Registering a company is a defined legal procedure, not a formality — the sequence below moves from reserving a company name through to holding the licences and tax registrations an operating business needs. Each step can be expanded for its required documents and considerations.
From activity definition and ownership review to registration, tax and operational approvals.
View Official Starting Points
Nominee shareholding arrangements are not a lawful substitute for foreign-ownership compliance.
These are not the same approval — a project can need several of them at once.
Work through these questions before choosing a structure — the right answer depends on the specific activity, not a general rule.
General orientation only. Investors should obtain qualified Thai legal, tax and regulatory advice before committing capital or signing binding agreements.
Tax, customs and operating obligations begin alongside company establishment. Businesses should understand registration, payroll, reporting, import duties and annual compliance before operations commence.
Tax and customs obligations run in parallel with company registration — corporate tax and VAT registration, payroll and social-security enrolment, and duty treatment on imports all apply once the business is operating, not only at setup.
Requirements vary by activity, ownership structure, transaction type and current regulation. Confirm applicable obligations directly with Thailand's Revenue Department, Customs Department and qualified professional advisers.
View Official Tax & Customs Resources
Standard corporate tax applies unless a specific BOI or other incentive reduces or exempts it for a promoted activity. Rate and treatment should be confirmed directly with the Revenue Department.
Applies to most goods and services; registration is required once turnover thresholds set by the Revenue Department are met.
Applies to specified payment types (e.g. services, royalties, dividends), with rates that can vary by payment type and recipient.
Applies to certain businesses outside the standard VAT system, such as some financial and real-estate transactions, where applicable.
Apply to imported goods, subject to standard tariffs, applicable free-trade-agreement preferences, or BOI/estate-specific treatment where granted.
Applies where related-party transactions are involved, under Revenue Department rules, where applicable.
Thailand maintains a network of double-tax agreements; applicability depends on the investor's home jurisdiction and structure.
Employers must withhold personal income tax from salaries and register employees with the Social Security Office.
Thai companies must keep statutory accounting records and file audited annual financial statements.
Promoted companies must maintain accounting records that separately demonstrate compliance with their specific incentive conditions.
Moving capital or profits out of Thailand requires supporting documentation under Bank of Thailand foreign-exchange regulations.
No tax rate is stated here without naming the tax and pointing to the official source below. Always confirm current rates, thresholds and exceptions directly with the Revenue Department or a qualified tax adviser before relying on any figure.
Location Shapes Cost, Talent, Logistics and Incentive Potential.
Thailand's commercial and administrative center, with the deepest concentration of headquarters, professional services and international connectivity.
Chonburi, Rayong and Chachoengsao form Thailand's flagship advanced-industry corridor, with dedicated incentive and infrastructure support.
A manufacturing and distribution base close to Bangkok's consumer markets and logistics networks.
Anchored by Chiang Mai, a base for digital, creative, education and tourism-linked investment alongside food and agriculture.
Thailand's largest region by area, with agricultural depth, cross-border trade routes and emerging bioeconomy investment.
A base for food and seafood processing, rubber, the Halal economy, and tourism and wellness investment, with maritime and cross-border access.
Compare location, sector fit, infrastructure, talent and market access before narrowing the investment pathway.
Industrial estates and special zones — managed principally by the Industrial Estate Authority of Thailand (IEAT) — provide factory-ready land, utilities and estate-specific services. General Industrial Zones and Free Zones carry different customs and export conditions; environmental and factory approvals, and any land-related or foreign-specialist privileges, depend on the specific estate, zone and promoted activity.
Invest, Establish and Mobilize the Right Talent.
A visa permits entry or stay. It does not automatically grant permission to work. A separate work authorisation or an applicable integrated programme may be required.
Does not itself authorize work — the Department of Employment work permit is a separate step.

Official information (opens in a new tab)Current availability and procedure must be confirmed directly with the responsible authority before relying on this route.
Official information (opens in a new tab)As of the February 2025 restructuring, the former Talent, Investor and Executive SMART categories were removed and merged into the LTR Visa — not every founder or digital worker automatically qualifies for SMART-S; targeted-industry and certification criteria apply.
Official information (opens in a new tab)Eligibility criteria were loosened in January 2025 but remain category-specific — not every investor or remote worker qualifies; current criteria must be checked directly.
Official information (opens in a new tab)
The correct route depends on the purpose of travel, sponsoring entity, proposed activity and whether work authorisation is required. Always verify the current process with the responsible Thai authority.
Spouse and dependant pathways exist under several of the categories above (including LTR and SMART-O). This is general orientation only, not immigration advice — confirm the applicable route directly with the responsible authority.
Tourist status is not a work-authorisation route. The Destination Thailand Visa (DTV) also should not be described as a substitute for company-sponsored employment or a work permit. Applicants must confirm permitted activities directly with the responsible authority.
Identify the Correct Visa Purpose
Match the actual activity — business visit, employment, investment, or long-term residence — to the right category.
Confirm Nationality and Current-Location Eligibility
Check that the chosen application channel is available for the applicant's nationality and location.
Review the Official Category Requirements
Read the current criteria directly from the responsible authority before preparing documents.
Prepare Sponsor and Project Documents
Assemble the company, project or personal documentation the category requires.
Apply Through Thai e-Visa or the Responsible Programme
Submit the application through the correct official channel (e.g. Thai e-Visa, BOI, TIESC).
Receive the Visa Decision
Await the responsible authority's decision on the application.
Complete Entry and Stay Requirements
Fulfil any entry, registration or reporting requirements tied to the visa.
Obtain Work Authorisation Before Starting Employment
Secure the applicable work permit or digital work-permit equivalent before beginning work.
Maintain Reporting, Extension and Renewal Compliance
Keep up with 90-day reporting, extensions and renewals as required by the category.
Thailand participates in ATIGA (upgrade negotiations completed) and RCEP (in force), alongside its bilateral agreements. Neither ATIGA nor RCEP provides automatic zero-duty access for every product — preferential treatment depends on the product's tariff classification and whether it meets that agreement's specific rules of origin.
Identify the Correct HS or AHTN Code
Classify the product correctly before assessing any duty or agreement.
Confirm the Normal Tariff
Check the standard, non-preferential duty rate for that classification.
Identify Any Applicable Preferential Agreement
Determine whether ATIGA, RCEP, an ASEAN+1 agreement, or a bilateral agreement could apply.
Confirm Product-Specific Rules of Origin
Check the exact origin criteria the product must meet under that agreement.
Verify Direct-Consignment Requirements
Confirm the shipping route meets the agreement's direct-consignment conditions.
Obtain Valid Origin Documentation
Secure the correct certificate of origin or origin declaration, including e-CO where available.
Confirm Product Registration and Standards
Check any required product registration or standards compliance (e.g. TISI, FDA) before export or import.
Complete Customs Documentation
File the required customs declarations through Thai Customs' digital systems.
Retain Supporting Records
Keep origin, valuation and compliance records for the retention period customs authorities require.
