Belgium Issues a Consultation on the Pillar Two IIR Top-up Tax Return
On March 19, 2026, Belgium issued a Consultation on the Pillar 2 IIR Top-Up Tax Return.
Pension funds are subject to a number of specific provisions under the Pillar Two rules. In this article we look at some of the key aspects of Pillar Two that impact on Pension Funds.
Excluded Entities
Article 1.5.1 of the Model Rules provides that a Pension Fund and certain other related entities are excluded entities for Pillar Two purposes.
This is important as excluded entities are not subject to top-up tax or any obligation to apply an income inclusion rule or under-taxed payments rule. However, excluded entities are still taken into account for the purposes of determining whether the MNE group has exceeded the 750 million consolidated revenue threshold.
• An excluded entity must hold directly or indirectly at least 95% of the value of the entity; and
• The entity must operate ‘exclusively or almost exclusively’ to hold assets or invest funds or carry out activities that are ‘ancillary’ to the activities of the excluded entity.
An entity owned by an excluded entity can also be treated as an excluded entity where at least 85% of the value of an entity is owned (directly or indirectly) by one or more excluded entities (excluding pension services entities), and where substantially all of the entity’s income is dividends or equity gains or losses excluded from the Pillar Two GloBE income or loss calculation.
