BOI TISO: A Practical Guide for Service and Sales Businesses in Thailand

What is TISO?

The Trade and Investment Support Office (TISO) is a business structure promoted by the Board of Investment (BOI), a government agency responsible for attracting and facilitating investment in Thailand. The BOI provides various promotional benefits to both Thai and foreign businesses to stimulate economic growth and encourage foreign direct investment. Under  BOI Announcement No. Sor 3/2564, TISO offers non-tax incentives, such as simplified work permits and limited land ownership options.

TISO is ideal for foreign companies seeking a regional base in Thailand without typical Thai ownership requirements. However, with a requirement for annual sales and administrative expenses of at least THB 10 million, TISO is best suited for medium to large businesses and may not be the right fit for smaller enterprises.

Foreign companies often choose TISO for sales and service activities as part of their regional headquarters, leveraging its simplified setup process and operational flexibility. While TISO doesn’t provide tax incentives, its streamlined procedures make it an excellent option for firms prioritizing efficiency and control over their business operations in Thailand.

Key Benefits of TISO

TISO offers several compelling advantages for foreign businesses seeking to establish a presence in Thailand. These benefits make it an attractive option for companies focused on streamlined operations and regional growth.

1. Full Foreign Ownership

TISO allows businesses to be entirely foreign-owned, bypassing Thailand’s usual restrictions on foreign shareholding. This makes it a practical solution for companies that prefer full control over their operations.

2. Streamlined Visa and Work Permit Processing

Foreign employees of TISO companies benefit from expedited visa and work permit approvals through the BOI Single-Window Service Center. This simplified process reduces delays and ensures quicker onboarding of skilled staff.

3. Land Ownership Options

TISO companies are permitted to own land for specific purposes under BOI promotion, subject to the following conditions:

• Office use: Up to 5 rai (8,000 m²)

• Employee housing: Up to 20 rai (32,000 m²)

Eligibility for land ownership requires a minimum paid-up capital of THB 50 million, and the land must be used for BOI-approved purposes. If TISO status is revoked, the land must be sold within a year.

4. Feasibility Study Residency

TISO allows foreign staff to stay in Thailand to conduct feasibility studies, supporting early-stage business planning and decision-making. This benefit enables smoother entry into the Thai market.

5. Non-Tax Incentives Only

While TISO provides significant operational benefits, it is important to note that it does not include tax incentives or merit-based benefits available under other BOI promotion categories.

Eligibility Requirements for TISO

To qualify for BOI promotion under the Trade and Investment Support Office (TISO) category, businesses must meet specific criteria. These requirements are designed to ensure that eligible companies align with Thailand’s economic goals and TISO’s purpose.

1. Annual Sales and Administrative Expenses

TISO companies are required to maintain a minimum of THB 10 million (approximately USD 287,000) in annual sales and administrative expenses. This includes costs such as office rent, employee salaries, and other operational expenses, making TISO more suitable for medium to large enterprises.

2. Approved Business Scope

The company’s business plan must strictly align with BOI-approved TISO activities. Clear documentation of proposed services and operations is essential for approval.

Limitations and Drawbacks

While TISO offers significant advantages, businesses should also be aware of its limitations and potential challenges:

1. No Tax Incentives

TISO provides non-tax benefits only, such as visa facilitation and land ownership options. It does not include any corporate income tax exemptions or reductions, unlike other BOI promotion categories.

2. Separate Accounting for Out-of-Scope Activities

If a TISO company operates activities outside the BOI-approved scope, it must maintain separate accounting systems for these activities to ensure compliance. This can increase administrative complexity.

3. High Expense Requirements

The annual minimum expense requirement of THB 10 million (approximately USD 287,000) may pose a challenge for smaller businesses or startups, making TISO more suitable for medium to large enterprises.

4. Approval Timeline

The TISO approval process typically takes 2–4 months, with the potential for delays if the BOI requests additional information or clarifications. Businesses should plan accordingly to account for these timelines.

Application Process

The application process for TISO status involves several key steps, ensuring that businesses meet the BOI’s requirements and maintain compliance.
