Starry Research | "BOI Series" Issue 3: The Application Process for BOI

When it comes to investing and setting up operations in Thailand, the topic of "BOI" is almost always unavoidable. However, most people do not have an accurate understanding of what BOI actually is, and there are quite a few misconceptions about it. Starry will publish a series of articles on "BOI" to provide a detailed introduction to all aspects of BOI and help more businesses understand it.

In the first two issues, we introduced what BOI is, the incentives offered by BOI, the contents of an Investment Promotion Certificate, as well as the conditions and criteria for applying for investment promotion from BOI. In this issue, we will introduce readers to the BOI application process.

2. Applying for Approval to "Commence Operations" After Project Approval

(1) Time Requirements for "Commencement of Operations"

Within 36 months from the date of issuance of the Investment Promotion Certificate by BOI, the beneficiary (the holder of the Investment Promotion Certificate, hereinafter the same) must obtain approval to commence operations and begin operations. In general, the specific commencement date of operations will be stated in the Investment Promotion Certificate.

If operations indeed cannot be commenced within 36 months, the beneficiary may simultaneously apply for an extension of both the commencement of operations period and the machinery importation period. In such cases:

Extension applications may be submitted a maximum of 3 times, with each extension period not exceeding 1 year. If the beneficiary only needs to extend the commencement of operations period, they may apply for 1 extension, with the extension period not exceeding 1 year.

If the beneficiary is still unable to commence operations as authorized upon the expiry of the prescribed period, the Investment Promotion Certificate will be revoked, and the beneficiary will be required to pay back taxes, fines, and bear other related penalties.

It should be noted that, according to BOI's definition, "commencement of operations" refers to the beneficiary having completed all preparations and investments as stipulated in the conditions of the Investment Promotion Certificate, and does not refer to the beneficiary commencing the production or sale of goods or services. Therefore, beneficiaries may commence production, sales, and enjoy various incentives before obtaining approval to commence operations. However, if approval to commence operations has not been obtained upon the expiry of the prescribed commencement of operations period, the Investment Promotion Certificate will be revoked, and the beneficiary will be required to pay back the tax benefits enjoyed, as well as related fines and surcharges.
