On December 22, 2023, the Federal Council decided to levy the supplementary tax in Switzerland from January 1, 2024.

The minimum taxation will be implemented temporarily by ordinance. It will be levied in the form of a national supplementary tax. Switzerland thus ensures that large, internationally active corporate groups with a turnover of more than EUR 750 million are taxed at a minimum rate of 15% in Switzerland.

The vast majority of EU member states and other industrialized nations such as the UK and South Korea will apply the regulations from the same date.

However, the Federal Council is refraining from bringing the international supplementary tax (IIR and UTPR) into force for the time being. It will monitor further international developments in this regard and decide on their introduction at a later date, if appropriate.

The regulation is available here.
