On 8 January 2020, the Luxembourg tax authorities issued a new
Circular n° 168bis/1 (the
“Circular”) in order to provide
guidance on the interpretation of the interest deduction limitation
rules (“IDLR”) laid down in Article
168bis of the Luxembourg income tax law
(“LITL”).
Article 168bis of the LITL has transposed the Council Directive
(EU) 2016/1164 of 12 July 2016 laying down rules against tax
avoidance practices (“ATAD 1”) into
Luxembourg law and has been applicable since 1 January 2019. Since
the Circular merely has clarifying character with regard to the
interpretation of existing legal provisions and does not constitute
a new legal basis itself, the IDLR shall be interpreted according
to the Circular for all tax years from 2019.
