Double Tax Agreement Singapore and Thailand

Understanding the Double Tax Agreement Between Singapore and Thailand

When it comes to cross-border investments, taxation can be a major concern for businesses. If you are planning on investing in Singapore or Thailand, it is important to understand the double tax agreement (DTA) between these two countries.

What is a Double Tax Agreement?

A DTA is a tax treaty between two countries that aims to prevent double taxation of income and assets that may arise due to the jurisdictional differences of tax laws. Singapore has signed DTAs with more than 80 countries, including Thailand, to provide relief to businesses, investors, and individuals on their tax liabilities.

What Does the Singapore-Thailand DTA Cover?

The Singapore-Thailand DTA covers various types of taxes, including income tax, corporate tax, and capital gains tax. Singapore residents who earn income from Thailand will only be taxed in Thailand, and vice versa. Additionally, the treaty provides tax exemptions for certain types of income, such as royalties, interest, and dividends.

One notable provision of the DTA is the avoidance of double taxation for companies with a permanent establishment (PE). A PE refers to a fixed place of business in one country where a foreign company conducts its business activities. Without a DTA, the foreign company may be subject to tax in both countries, creating a double taxation scenario.

Under the Singapore-Thailand DTA, if a Singaporean company has a PE in Thailand, the company will only be taxed in Thailand on the income that is attributable to the PE. However, if the company does not have a PE, it will only be taxed in Singapore.

Benefits of the Singapore-Thailand DTA

The Singapore-Thailand DTA provides several benefits for businesses and investors. Firstly, it reduces the tax burden on cross-border investments and transactions, making it more attractive for businesses to invest in either country.

Secondly, the DTA promotes economic cooperation and trade between Singapore and Thailand by removing tax obstacles that may hinder business activities.

Lastly, the DTA provides a transparent and predictable tax system for businesses, allowing them to plan their finances more effectively.


In conclusion, the Singapore-Thailand DTA is an important treaty that provides tax relief and promotes economic cooperation between the two countries. Businesses and investors planning to invest in Singapore or Thailand should take advantage of the provisions included in the DTA to mitigate their tax burdens and improve their financial planning. As such, it is recommended that all businesses operating in either country should seek the advice of a professional tax advisor to fully understand the implications of the DTA and apply the rules in their tax planning.
