On 8 November 2022, the Foreign Affairs Committee of Argentina's Chamber of Deputies approved the draft bill for the ratification of the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting (MLI). After the internal ratification process is completed, Argentina must deposit its ratification instrument to bring the MLI into force for its covered agreements (tax treaties).

The MLI will generally enter into force for a particular covered agreement on the first day of the month following a three-month period after both parties to the covered agreement have deposited their ratification instrument. Once in force, the provisions of the MLI will generally apply for a covered agreement from 1 January of the year following its entry into force in respect of withholding taxes, and for all other taxes with respect to taxable periods beginning on or after the expiration of a 6-month period following the date of entry into force. However, for Argentina's own application of the MLI in respect of other taxes, Argentina has taken the reservation that the MLI will apply for tax periods beginning on or after 1 January of the next calendar year following a six-month period after the MLI's entry into force.
