Further updates: BOI adds new activity scopes for International Business Centres and Trade & Investment Support Offices

Home » Further updates: BOI adds new activity scopes for International Business Centres and Trade & Investment Support Offices

Further to its announcement of a new promotional category for Digital Services Platforms and Digital Content, the Board of Investment (BOI) has introduced revisions to the scope of activities conducted by International Business Centres (IBCs[1]) and Trade and Investment Support Offices (TISOs) that do not operate as treasury centres. The revisions will allow them to lend funds to affiliated enterprises in and out of Thailand following current exchange control regulations.

These revisions come as part of the BOI’s efforts to strengthen Thailand’s position as a hub for international business by permitting more flexibility to Thailand-based multinational corporations in providing the necessary support services to companies within the same corporate group. However, as previously mentioned, these revisions do not apply to IBCs and TISOs that are considered Treasury Centres[2], which are entities that conduct business activities related to the management of foreign currency funds for a Conglomerate Group[3].

According to BOI officials, if an entity that already operates as a treasury centre seeks to apply for BOI promotion as an IBC or TISO, it will not be required to declare its lending activities in their application. However, this is unless they intend to lend out to affiliate companies using Thai Baht, in which case they will be required to declare lending activities in their application. Moreover, applicants must be aware that providing loans in Thai Baht can only be provided to affiliate companies in Thailand, Vietnam, and countries bordering Thailand.

BOI officials also reiterate that loans denominated in foreign currencies are not subject to limits in terms of the amount. However, IBCs and TISOs must be aware of the purpose of providing these funds to affiliate companies, as it would need to be under the goals and objectives of IBCs and TISOs; which is to support prospective trade and investment activities. On the other hand, loans denominated in Thai Baht may not be subject to limitations in the amount disbursed; however, they can only be lent out to affiliate companies in Vietnam and other countries bordering Thailand to support trade and investment

Importantly, the lending activities are still subject to other exchange control regulations including the Exchange Control Act B.E. 2485, Ministerial Regulation No. 13 B.E. 2497, the Notification of the Ministry of Finance regarding Exchange Control, and the Notice of the Competent Officer on Rules and Practices regarding Currency Exchange (B.E. 2547).

In addition, IBCs and TISOs that wish to conduct these activities must also adhere to certain requirements which are summarized accordingly:

Type of Entity


Requirements Additional Incentives
International Business Centres (IBCs)


–       An IBC must provide a clear business plan that outlines the type of support services it will provide to affiliated companies, particularly those about providing loans.

–       In addition to providing loans to affiliated companies, the IBC must also provide at least one other service activity listed in the pre-existing scope of services for IBCs and TISOs.

Under the BOI’s revisions, IBCs will be eligible for exemptions on import duties for machinery on top of other tax and non-tax incentives
Trade and Investment Support Offices (TISOs)


–       Like IBCs, TISOs must provide a clear business plan that highlights the scope of the support services provided to their affiliate companies, including any proposed lending services.

–       A TISO must conduct at least one other support service prescribed by the BOI.


The revisions highlight that TISOs will be eligible for non-tax incentives.

What are IBCs and TISOs?

Unveiled by the BOI in 2018, the IBC scheme is a structure that aims to incentivise multinational companies to establish regional or global hubs in Thailand. Applicants seeking to establish such a company in Thailand are eligible for B1 benefits which only covers non-tax incentives, including permission to remit funds abroad in foreign currencies, purchase land in the country, and apply for permits to bring in foreign specialists; on top of exemptions on import duties for machinery and raw materials used for producing exports goods. However, IBCs may be able to avail tax incentives from the Revenue Department, which include exemptions on corporate taxes[4], Withholding Tax[5], Specific Business Tax[6], personal income tax[7].

Moreover, companies applying to be promoted as International Business Centres must conduct at least one of the activities listed in the BOI’s scope of activities, including business planning, procurement of war materials, economic and investment analysis, and technical support.

On the other hand, TISOs do not conduct business activities of their own, but rather provide ancillary activities that may contribute towards potential investment into Thailand[8]. This means that functions held by TISOs are particularly versatile, though they are required by the BOI to have annual expenditures of at least THB 10 million to ensure that only applicants that have the capacity for a considerable impact on trade and investment are eligible for the promotion.

Unlike IBCs, TISOs are usually only eligible for non-tax incentives[9]. Those applying for benefits under a TISO will be required to prepare documents explaining the scope of their service processes and other corporate information such as its source of funds, manpower requirements, and marketing plans.  Furthermore, the debt-to-equity ratio must not exceed 3:1.
