Argentina has signed the multilateral instrument on 7 June 2017, aiming to facilitate the implementation of tax related measures to Prevent Base Erosion and Profit Shifting (MLI).

At the signing ceremony, Argentina introduced its 17 tax treaties with other jurisdictions that Argentina would like to designate as Covered Tax Agreements (CTAs), that is, to be modified by the MLI. In addition to the list of treaties, Argentina has also submitted a provisional list of reservations and notifications (MLI items) relating to the various provisions of the MLI.
