The anti-hybrid mismatch rules of the EU Anti-Tax Avoidance Directive (ATAD 2) aim to prevent situations of a double deduction and a deduction without a corresponding inclusion of the income at the level of the recipient resulting from a hybrid mismatch. All EU Member States have implemented ATAD2 in their domestic laws as from 1 January 2019 (for Belgium) or as from 1 January 2020 and 1 January 2022 (for a.o. the Netherlands and Luxembourg).
It is noted that EU Member states can introduce rules that go beyond the minimum standards of the ATAD2 directive. An example of this is the introduction of the ATAD2 documentation requirement in the Netherlands. Following the Dutch ATAD2 documentation requirement, all Dutch taxpayers should have documentation available in their administration that shows the (non-)applicability of the ATAD2 rules.
