As of 1 January 2019, all Member States shall apply new legally binding anti-abuse measures that target the main forms of tax avoidance practiced by large multinationals.
The rules build on global standards developed by the OECD in 2015 on Base Erosion and Profit Shifting (BEPS) and should help to prevent profits being siphoned out of the EU where they go untaxed. In detail:
Further rules governing hybrid mismatches to prevent companies from exploiting mismatches in the tax laws of two different EU countries in order to avoid taxation, as well as measures to ensure that gains on assets such as intellectual property moved from a Member State's territory become taxable in that country (exit taxation rules) will come into force as of 1 January 2020.
