ASEAN Briefing-Thailands Investment Outlook for 2018 (002)

Thailand’s Board of Investment (BOI) offers a range of tax and non-tax incentives to foreign companies making investments that are deemed highly beneficial to the Thai economy.

In 2015, the BOI announced a new seven-year investment promotion strategy (2015-2021) that offers special privileges to foreign investors. Under the strategy, tax-based incentives are granted according to the group classification (A or B) for the activities and the merit of the project (if any), whereas non-tax benefits are available to all projects regardless of the type of activity or conditions.

Activity-based incentives

These business activities are classified into groups based on the level of importance.

While group A activities receive tax as well as non-tax benefits, group B activities receive mainly non-tax benefits and certain import duty benefits, if applicable. Activities falling under each group classification and the incentives granted for each group are immediately below.

A1: Knowledge-based activities, focusing on R&D and design to enhance the country’s competitiveness.

A2: Activities in infrastructure for the country’s development, activities using advanced technology to create value-added, with none or very few existing investments in Thailand.

A3: High technology activities which are important to the country’s development, with a few investments already existing in Thailand.

A4: Activities with lower technology than A1-A3 but add value to domestic resources and strengthen supply chain.

B1-B2: Supporting industries that do not use high technology but are still important to value chain.

  • Deduction from net profit for ten years of up to 70 percent of the investment amount in addition to the normal depreciation deductions.

 Additionally, tax incentives are granted to the following new categories of activities.
