Revenue Department Begins Taxing Foreign-Sourced Income

As of 1 January B.E. 2567 (2024), the Revenue Department has enforced its department instruction P. 161/2566 to tax any Thai citizen or a foreigner with Thai residency, who receives an income within Thailand. Sources of income earned outside of Thailand are also taxable by the Revenue Department, but only if that income is brought into the country. Income earned before 2024 is exempt from taxation and can be brought into Thailand freely.

This instruction falls under Section 41 paragraph 2 of the Revenue Code regarding income assessment, which considers sources of incomes within Thailand and overseas into account for an income tax.

However, there is an exemption from being subject to income tax in Thailand by meeting one of the following conditions:

  1. The individual must not reside in Thailand for 180 days or more in a particular tax calendar year.
  2. Invest in a foreign investment fund or Depositary Receipt.
  3. Does not bring an income from overseas into Thailand.

Case Examples

Case 1: An individual who resided in Thailand for 300 days, worked in Thailand and received a wage from an employer in the United Kingdom. Therefore, this Thailand resident is subject to pay income taxes as his residency period is more than 180 days by the virtue of Section 41 of the Revenue Code.

Case 2: An individual residing in Australia who worked for the employer from Thailand and received a salary from such an employer. For this case, this individual is subject to pay an income tax for Thailand, as this individual receives the income from the employer who operates a business in Thailand, as defined by Sections 40 and 41 of the Revenue Code.

Case 3: An individual was assigned to work for a Japanese company based in Thailand for 90 days and received a salary for 3 months from the parent company in Japan. As a result, this individual is not subject to pay income tax in Thailand, but is subject to pay the tax in Japan because Thailand and Japan have a double tax agreement.

Double Tax Agreement (DTA)

This agreement exempts any individual residing in Thailand and the country where Thailand has signed the agreement with from paying income taxes on both countries. To clarify, an individual can pay income taxes in the country where the individual is currently residing. The DTA has several purposes regarding income tax:

  1. Prevent double taxation for reducing financial burdens among individuals.
  2. Avoid conflicts on taxing rights ensuring income is taxed once or at a reduced rate.
  3. Ensure fair treatment on taxation from discrimination.
  4. Prevent tax evasion and fraud by sharing information with the contractual party.
  5. Promote economic activity in stimulating cross-border transactions and investments between the treaty countries.

As of 9th October 2023, Thailand has signed the DTA with 61 countries. Nevertheless, the individual may be subject to double taxation in Thailand and the country where Thailand is not a contractual party to the DTA.
