International Tax Treaties and Double Taxation Avoidance

Singapore has signed Avoidance of Double Taxation Agreements (DTAs), limited DTAs, and Exchange of Information (EOI) Arrangements with around 100 jurisdictions. These agreements are designed to help businesses avoid being taxed twice on the same income in different countries, which is commonly referred to as double taxation.

DTAs allocate taxing rights between two jurisdictions and typically provide relief from double taxation by either exempting income earned in one country or providing a tax credit for taxes paid in the other country. By utilizing these treaties, businesses can ensure that they are not unfairly taxed on the same income in multiple countries.

Some of the key points regarding these agreements include:

• DTAs with around 100 jurisdictions: These treaties provide relief from double taxation by setting out which country has taxing rights over specific income (e.g., dividends, interest, royalties).
• Exchange of Information (EOI) Arrangements: These arrangements allow for the exchange of taxpayer information between countries to prevent tax evasion.
• Multilateral Convention to Implement Tax Treaty Related Measures (MLI): Some of Singapore’s DTAs have been amended by the MLI, which aims to prevent base erosion and profit shifting (BEPS).
• Arbitration Provisions: Some DTAs contain mandatory binding arbitration provisions or have been modified by the MLI to include such provisions. This helps resolve disputes regarding the interpretation of the agreement, ensuring fair treatment for businesses.
