The CRS MCAA provides details of the information that will be exchanged and when. It is a multilateral framework agreement. A specific bilateral relationship under the MCAA CRS only comes into force when the two jurisdictions have implemented the convention, submitted the necessary notifications in accordance with Section 7 and presented themselves to each other. The number in brackets behind each jurisdiction in the drop-down menu indicates the total number of bilateral exchange relations currently activated in relation to that jurisdiction. If, for a given jurisdiction, the number of exchange partners cited as sending CBC reports to the jurisdiction is greater than the number of exchange partners designated as recipients of cbC reports under the jurisdiction, this can be explained by the fact that a number of these partners are “non-reciprocal jurisdictions” (i.e., they have committed to sending CBC reports to their trading partners, but do not receive cbC reports from their exchange partner). Since more than 100 legal systems have committed to exchange information within the IRS, exchanges between legal systems are generally based on the multilateral convention on mutual tax assistance (convention), in which more than 100 jurisdictions participate, and the Multilateral Competent Authority`s (CRS MCAA) IRS Convention (CRS MCAA), which is based on Article 6. Legal systems can be based on a bilateral agreement, such as a double taxation agreement or an agreement on the exchange of tax information. In addition, some IRS exchanges will be organised on the basis of the relevant EU directive, agreements between the EU and third countries and bilateral agreements such as the agreements between the UK and the CDOT. A statement on the national authority`s multilateral agreement on country exchange of reports (CBC MCAA) of 1 October 2020 was published in the Official Journal. Relationships activated for the exchange of information on IRS As of August 2020, more than 2,500 bilateral relations have been activated for jurisdictions that have committed to exchange cbC reports, and the first automatic exchange of cbC reports took place in June 2018. These include exchanges between the 88 signatory states of the EU Competent Authority Convention, the CNC, between EU member states under the 2016/881/EU Directive and between signatories to bilateral agreements to exchange exchange agreements of competent authorities under double taxation agreements or exchange of tax information, including 41 bilateral agreements with the United States.
