BOI Promotion for Technology Businesses in Thailand: Which activity categories suit your tech businesses?

Thailand’s Board of Investment (BOI) framework offers promotion opportunities across software and digital-content development, digital platforms, cloud and data infrastructure, innovation facilities and smart-city solutions. These opportunities may be available to qualifying projects undertaken by both Thai-owned and foreign-owned companies; the key issue is whether the proposed project falls within an eligible BOI activity and satisfies the applicable conditions.

Technology businesses often operate across several functions, including product development, licensing, subscriptions, marketplace operations, consulting and infrastructure services. Those functions may fall under different BOI categories, attract different incentives or sit outside the promoted project altogether.

Selecting the right activity category therefore requires a close analysis of what the company will actually do in Thailand, including its development processes, personnel, expenditure, revenue model and project boundaries. This article outlines the principal BOI categories relevant to technology businesses and the practical distinctions that applicants should consider before applying.

Key takeaways

• Technology use alone does not establish BOI eligibility; the proposed activities and operational substance in Thailand are decisive.
• Activity 8.1 distinguishes the development of software, digital platforms or digital content from the modification of products already marketed or used to provide services.
• A SaaS or marketplace business must separate qualifying development work from subscription sales, commissions, advertising, trading or other commercial operations.
• Cloud services, data centres, data hosting and international high-speed marine communication circuits fall within infrastructure categories with distinct capital, capacity, licensing, certification and screening requirements.
• Smart City Area Development and Smart City System Development are separate categories; the former carries an express majority-Thai shareholding condition.
• BOI promotion does not replace Foreign Business Act analysis, sector-specific licensing or compliance with data protection, cybersecurity, employment and tax laws.

The BOI framework for technology businesses

The BOI’s 2026 Investment Promotion Guide places the principal technology-related categories within Section 8, covering digital industries, infrastructure and supporting activities. The categories most likely to be relevant are Activity 8.1 (digital technology), Activity 8.2 (digital infrastructure), Activity 8.3 (digital ecosystem-supported businesses) and Activity 8.4 (smart city development).

The activity description in an application should correspond to the work actually undertaken by the promoted project. A company may conduct both promoted and non-promoted activities, but the project boundaries, personnel, income and expenditure should be capable of being identified and supported. Approval of one project should not be treated as authorisation for every activity conducted by the company.

Incentive classifications also differ. Some categories carry corporate income tax incentives, while others provide principally non-tax benefits. Even within the same classification, special caps, location-based variations or project-specific conditions may apply.

Digital technology activities

Development of software, digital platforms and digital content

Activity 8.1.1 covers the development of software, digital platforms or digital content. It may be relevant to businesses developing proprietary software, SaaS products, artificial-intelligence applications, data-analytics tools, digital content or platform technology in Thailand. These examples are illustrative; the underlying development process remains the focus of the BOI analysis.

The published criteria require qualifying software, platform or content development processes in Thailand and annual qualifying investment of at least THB 1.5 million. This threshold is calculated by reference to the salary expenditure of Thai information-technology personnel additionally employed after the promotion application and/or temporarily employed Thai information-technology personnel, in accordance with the BOI criteria. Retail and wholesale sales of products are excluded from promotion under this category.

Activity 8.1.1 is classified in incentive Group A2. However, its corporate income tax exemption is subject to a special annual cap determined at 100% of actual qualifying expenditure incurred in the relevant year for which the incentive is claimed, including eligible Thai IT personnel costs and specified IT training and software quality-certification expenditure. Full operations must commence within 12 months after the promotion certificate is issued, without extension of that deadline.

A SaaS company carrying out substantive product development in Thailand may therefore have a potentially qualifying project. A company that merely markets subscriptions to software developed overseas, performs routine configuration or resells third-party software should not assume that it falls within Activity 8.1.1.

Modification of existing software, platforms and content

Activity 8.1.2 applies to qualifying modification of software, digital platforms or digital content that has already been marketed or used to provide services. The project must submit a modification plan and meet the annual THB 1.5 million qualifying salary-expenditure threshold for additional Thai information-technology personnel employed after the promotion application.

Activity 8.1.2 is classified in incentive Group B. It does not carry the basic corporate income tax exemption available to qualifying Group A projects, although other applicable benefits may include machinery import-duty exemptions and non-tax incentives. The criteria also restrict changing the promoted activity category and require full operations to commence within 12 months after the promotion certificate is issued.

The distinction between development and modification is commercially important, but it is not determined solely by whether existing code or third-party components are used. The BOI analysis should consider the maturity of the product, the scope of the work performed in Thailand, the development plan and whether the relevant software or platform is already being commercialised.

Platforms, marketplaces, consulting and mixed revenue

A digital platform may include qualifying development work, but operating a marketplace can also involve commissions, intermediary services, advertising, payment flows or trading activities. Those commercial functions should be analysed separately from the promoted development project, particularly where they may be restricted under the Foreign Business Act or require sector-specific approvals.

Technology consulting, implementation, system integration, localisation, maintenance and customer support do not automatically constitute qualifying development. The application should explain which activities create or materially modify the product and which activities are ancillary services or non-promoted operations.

Digital infrastructure

Activity 8.2 covers infrastructure businesses rather than companies that merely use third-party infrastructure to deliver a digital product. The fact that a SaaS application is hosted in the cloud does not make the SaaS provider a qualifying cloud-service operator.

Data centres

Data-centre projects are divided between high-energy-efficiency data centres (Activity 8.2.1.1) and other data centres (Activity 8.2.1.2). The published criteria include minimum IT load, telecommunications connectivity, redundancy, security, environmental and technical-certification requirements. Under BOI Announcement No. Sor. 3/2569, dated 15 July 2026, applicants in both categories must obtain preliminary approval from a BOI-designated subcommittee responsible for screening data-centre projects before submitting an application for investment promotion. The announcement also applies to certain pending applications and project amendments increasing IT Load by more than 30%.

Incentive classifications vary by energy-efficiency category and project location, and applicants should verify the classification applicable on the filing date against the controlling BOI announcement. In August 2026, the BOI announced a review of the data-centre screening framework following a national regulatory initiative. As a result, investors should confirm the prevailing screening criteria and procedures with the BOI immediately before filing.

Cloud services — Activity 8.2.2

Activity 8.2.2 may apply to operators of qualifying cloud infrastructure. The criteria include operation through at least two appropriately certified data centres in Thailand, minimum interconnection capacity, backup connections and specified information-security and service-management certifications. The category is classified in incentive group A2.

International high-speed marine communication circuits — Activity 8.2.3

Activity 8.2.3 covers international high-speed marine communication circuits and is classified in incentive Group A2. The project must obtain the relevant licence for these circuits from the competent telecommunications authorities identified in the BOI criteria before submitting an investment-promotion application. Investors should therefore address the licence and the sequencing of regulatory approvals at an early stage of project planning.

Data hosting — Activity 8.2.4

Activity 8.2.4 covers qualifying data-hosting services, including advanced processing such as GPU-based systems (Activity 8.2.4.1) and other data hosting (Activity 8.2.4.2). Both subcategories require investment of at least THB 5 billion, excluding land and working capital, together with applicable infrastructure and certification conditions. Advanced-processing data hosting is classified in incentive Group A2; other data hosting is classified in Group A3.

Digital ecosystem-supported businesses

Activity 8.3 is intended for businesses that operate qualifying facilities and programmes supporting innovation and technology development. It includes innovation parks, maker spaces or fabrication laboratories, and qualifying co-working spaces.

These categories impose requirements concerning matters such as service area, infrastructure, equipment, incubation or mentoring programmes, management capability and investment. For example, the published criteria prescribe a minimum service area of 1,000 square metres for an innovation park and 2,000 square metres for a co-working space, with the co-working category also requiring minimum investment of THB 10 million excluding land and working capital.

Ordinary office leasing, a conventional serviced office or a consulting business should not be assumed to qualify merely because it serves technology companies. The project must satisfy the specific facility and programme conditions of the relevant category.

Smart city development and systems

Smart City Area Development

Activity 8.4.1 concerns the development of a qualifying smart city area. The published criteria require suitable communications infrastructure, a smart-environment system and at least one additional recognised smart system, together with data storage and management connected to an open-data platform. Prior approval, performance indicators and public consultation requirements also apply.

Thai nationals must hold at least 51% of the registered capital of the project company. This express ownership condition makes Activity 8.4.1 unsuitable for a majority foreign-owned structure unless the ownership model is revised in a legally compliant manner.

Smart City System Development

Activity 8.4.2 covers the development, installation and provision of services for one or more recognised smart-city systems. The project must form part of a smart-city development project approved by the BOI or the responsible smart-city authority.

Unlike Activity 8.4.1, the activity-specific criteria for Activity 8.4.2 do not expressly require 51% Thai shareholding. This does not establish an unconditional right to full foreign ownership: the general BOI foreign-shareholding criteria, the Foreign Business Act and any other applicable restrictions must still be considered. The project must also form part of an approved smart-city development project; merely supplying technology capable of use in a smart city is insufficient.

Both smart-city categories are classified in incentive Group A2. For qualifying projects located in the Eastern Economic Corridor (EEC), the 2026 Guide provides for a further 50% reduction in corporate income tax for five years following the expiry of the corporate income tax exemption period. This is a reduction of the applicable tax liability, not a deduction from taxable income; the precise entitlement and calculation remain subject to the governing conditions and the project approval.

Mixed or overlapping technology business models

Many technology companies combine development with licensing, subscriptions, commissions, consulting, maintenance or infrastructure services. A single commercial description may therefore conceal several legally distinct activities.

The application strategy should identify the promoted project and map each revenue stream, cost centre and operational function to that project. Where promoted and non-promoted activities coexist, the company should consider how it will maintain accounting, staffing and documentary evidence sufficient to demonstrate compliance with the promotion certificate and applicable tax treatment.

Intellectual-property ownership is not the only relevant factor. The BOI may also examine where development occurs, who performs it, how personnel and expenditure are allocated, whether work is outsourced and whether the Thai project has substantive responsibility for the relevant product or system.

Comparative overview

The table is illustrative. Eligibility, conditions and incentives depend on the applicable rules, the approved project and the facts presented to the BOI.

Foreign ownership and related regulation

BOI promotion may facilitate foreign ownership of a promoted activity, but it should not be treated as a blanket exemption for the company’s entire business. Where the Foreign Business Act applies, a foreign-owned promoted company may be able to obtain a Foreign Business Certificate under section 12 for the promoted activities. Unrelated or non-promoted operations require a separate analysis.

The project may also require licences or compliance under telecommunications, digital-platform, electronic-transactions, personal-data-protection, cybersecurity, employment, immigration, tax or other sector-specific laws. BOI approval does not replace those obligations.

Practical classification and application considerations

Before selecting an activity category, the investor should prepare an operational map showing the work performed in Thailand, the people responsible for that work, the expected expenditure, the technology and intellectual property used, the revenue generated and any outsourced or offshore functions. The analysis should then test those facts against the official activity description and conditions.

The business plan, technical narrative, staffing plan and financial projections should use consistent assumptions. Overstating local development or combining qualifying and non-qualifying functions without clear boundaries can create difficulties during application review and post-promotion compliance.

Conclusion

BOI promotion for technology businesses in Thailand is activity-specific. The correct category depends on the substance of the proposed operations—not the company’s branding, the use of technology or the attractiveness of a particular incentive package.

An early classification exercise can help an investor align its ownership structure, staffing plan, expenditure and regulatory approvals with a supportable BOI application. It can also identify non-promoted activities that require separate licensing, foreign-business or tax analysis.
