Luxembourg introduces amendment to interest deduction limitation rule (“IDLR”): positive impact on Luxembourg securitization vehicles

As from 1 January 2019, as part of the implementation of the EU measures covered in (the 1st) anti-tax avoidance directive dated 12 July 2016, Luxembourg has introduced article 168bis in its income tax law (“LITL”). 

Under this rule, in short, net borrowing costs incurred by a taxpayer will annually (to the extent these costs are not deductible on other legal grounds) be deductible up 30% of its EBITDA or EUR 3 million, whichever is higher. Net borrowing costs (being essentially the positive difference between the amount of interest costs, or cost economically equivalent to interest, reduced by the amount of interest income, or income equivalent to interest) that are not deductible may be carried over for future use (within limits).

The rules contain various categories of exceptions, one of which is that so-called ‘standalone taxpayers’ are not subject to this rule. An entity is considered a ‘standalone entity’ when it is – briefly put – neither itself held by a so-called ‘associated enterprise’, not itself owns an interest in an ‘associated enterprise’.

The threshold to be considered ‘associated enterprise’ is by law placed at 25% (participation in shares, control or profit entitlement). This means that each entity having a single shareholder (such as a securitization vehicle that is typically held by a foundation) cannot be regarded as a ‘standalone entity’ and could therefore be equally impacted by the interest deduction limitation rule. As a consequence, Luxembourg securitization vehicles (organized as corporate entities and not as tax transparent partnerships) deriving income other than interest income (or income economically equivalent to interest income) could be subject to an actual corporate income tax liability.

 

Introduction of new notion of ‘single entity group’

Recently, however, with effect from 1 January 2024, the Luxembourg legislator introduced the concept of ‘single entity group’ and added such group to the list of entities benefiting from an exception to the application of the IDLR.

To qualify as a ‘single entity group’, a taxpayer must meet two cumulative conditions:

  • it must not be included in a consolidated group for financial reporting purposes; and
  • it must have one or more associated enterprises (and is therefore itself not a ‘standalone entity’) within the meaning of article 164ter(2) LITL (or a permanent establishment located in a state other than Grand Dutchy of Luxembourg) with the caveat that entities that are excluded from a consolidated financial statement due to their small size or insignificant interest are still considered part of a consolidated group for financial accounting purposes.

This means that, for example, a Luxembourg securitization vehicle itself held by a (Dutch) foundation (which is a typical set-up), and which thereby does not qualify as a ‘standalone entity’, can now qualifies as a ‘single entity group’.

As a consequence of being a ‘single entity group’ it may – upon request – fully deduct its exceeding borrowing costs provided that it can demonstrate that its equity-to-total-assets ratio is at least equal to (or greater than) the ration of the group, i.e. the ‘single entity group’. The taxpayer’s ratio is considered equal to the ratio of the ‘single entity group’ if the taxpayer’s ratio is lower than 2%. Whilst the wording of the relevant law provision is not overly clear, it effectively means that as long as the ‘single entity group’ does not itself borrow from associated enterprises (as defined in article 168ter(1)(18) LITL), it should be allowed to deduct all its net borrowing costs without limitation. For the purpose of this rule the threshold to qualify as ‘associated enterprise’ is lowered to 25% (instead of the general 50% threshold relevant for other tax law provisions).

The revised Article 168bis introduces a specific anti-abuse rule, ensuring that an arrangement or series of arrangements put in place to avoid, as a principal objective or as one of the principal objectives, the obligation to increase the amount of group capital for the purposes of determining the SEG ratio are to be disregarded when applying this provision.

These provisions are a welcome addition to the Luxembourg rules on IDLR and are expected to have a positive impact on, a.o., Luxembourg securitization vehicles, bringing the Luxembourg rules in this respect now on par with the rulings applicable in Ireland.
