As of 21 December 2018, 17 countries including Singapore have deposited their instrument of ratification.
On 21 December 2018, Singapore deposited the Instrument of Ratification for the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting (BEPS) (Multilateral Instrument or MLI). For Singapore, the MLI will enter into force on 1 April 2019.
An existing tax treaty of Singapore will be amended by the MLI only if both Singapore and the treaty partner have identified their tax treaty as a covered tax agreement and after both countries have ratified the MLI. At the point of ratification on 21 December 2018, Singapore intends for the MLI to apply to its existing 86 tax treaties.
