Latest Pillar 2 Developments

On February 9, 2026 the Belgian Tax Administration announced a change to the mechanism for making advance payments of Pillar 2 top-up tax under the IIR. 

As of 2026, advance payments for the IIR top-up tax will now have to be made individually (as opposed to for the group).

When making payments, entities will now have to use the structured communication available on MyMinfin, at entity level (per taxpayer), or generated via the tool provided by the FPS Finance, based on the entity’s company number (or entity bis number).

This doesn’t effect advance payments of QDMTT tax. 

On February 6, 2026, the Italian Revenue Agency approved the model for the GloBE tax Return. This is a consolidated form with information on the calculation of top-up tax under the IIR, UTPR and QDMTT.
