Luxembourg’s Parliament adopts draft law implementing EU Anti-Tax Avoidance Directive

  • Share

On 18 December 2018, the Luxembourg Parliament adopted draft law n°7318 (the Law) implementing the European Union (EU) Anti-Tax Avoidance Directive1 (ATAD), which introduces a limitation to interest deductibility, Controlled Foreign Company (CFC) rules and rules countering hybrid mismatches with the EU. The Law also amends the existing exit taxation regime (including provisions relating to inbound transfers) and the General Anti-Abuse Rule (GAAR). Two existing domestic provisions, being the conversion of debt into equity and the amendment of the permanent establishment (PE) definition, are also amended by the aforementioned law.

The Law, which is expected to be published before the end of December, should generally be in line with the initial draft law of June 2018,2 as amended early December.3 As recently announced by Luxembourg’s Minister of Finance,4 the Law will undergo a further amendment in 2019 to extend, with retroactive effect to 1 January 2019, the interest limitation rules to companies that are within a fiscal unity.

The provisions of the Law apply to tax years starting on or after 1 January 2019, except for the provisions regarding exit taxation that will apply to accounting years, starting on or after 1 January 2020.

A detailed Tax Alert discussing the provisions of the Law as well as their implications will be forthcoming.
