Termination of pre-2015 rulings in the 2020 Budget law

With respect to the 2020 Budget law pre-2015 tax rulings will no longer be binding after the end of the tax year 2019. For companies with a tax year diverging from the calendar year, the ruling is no longer binding already for their current tax year. Taxpayers may request a new ruling (valid for five years) under the procedure in place since 1 January 2015.

Stating the obvious, pre-2015 rulings remain binding for the years prior to the 2020 tax year, to the extent applicable law, case law, and underlying facts did not change compared to the situation prevailing at the time the ruling was obtained. Merely rendering those rulings non-binding through the 2020 Budget law normally does not affect the filing position of tax payers previously benefiting from the certainty of a pre-2015 ruling. It does create the opportunity for tax authorities to change their interpretation of applicable tax law in such cases. Taxpayers should, together with their tax advisers, assess whether or not such change seems likely, and furthermore whether it would be worthwhile to seek a new tax ruling.

ATAD 2 law

The ATAD 2 law extends the scope of existing anti-hybrid rules to mismatches with third countries and to a wider array of hybrid mismatches. These rules will apply for tax years starting on or after 1 January 2020, except for the reverse hybrid rules which will apply only as of tax year 2022. They target certain mismatch outcomes (deduction without inclusion, double deduction or double non-taxation) which result from the hybridity of a financial instrument, a legal entity or a permanent establishment. The rules may increase the tax base of Luxembourg taxpayers either by denying currently deductible payments or requiring to include income that was so far exempt. Reverse hybrid rules may result in tax transparent entities becoming subject to corporate income tax on part or all of their income. 

Several key concepts on the ATAD 2 law need further clarification. Pending administrative guidance, taxpayers may find useful indications in parliamentary documents, especially in the opinion of the State Council.
