The OECD introduced the BEPS project in 2013, an initiative to combat these international tax evasion practices. This initiative is constantly updated through the work group created in 2015 to promote an inclusive framework for the implementation of the BEPS project measures developing international standards.

On 7 June 2017, Andorra signed the Multilateral Convention to implement Tax Treaty related measures to Prevent the Base Erosion and Profit Shifting (MLI), which transposes more than 2,000 tax treaties world-wide into an international regulation. The MLI offers governments specific solutions to fight against harmful tax practices, to prevent the abuse of the agreement and a country-by-country report, among other things. In the Principality, the MLI came into force on 1 January 2022.

At the same time, on 19 October 2018, Andorra adhered to the OECD multilateral agreement that allows for the exchange of information on a country-by-country basis with all the competent authorities signatory to the agreement (reciprocal jurisdictions). This agreement is part of the commitments made to international standards and to the implementation of OECD-led reforms in relation to BEPS.
