On 20.11.2024, the Federal Council decided to amend the Ordinance on the Minimum Taxation of Large Corporate Groups (Minimum Taxation Ordinance) due to the entry into force of the international supplementary tax (Income Inclusion Rule, IIR). This international supplementary tax extends the Swiss supplementary tax already introduced in 2024.
In order to implement the IIR in Switzerland as of January 1, 2025, the Minimum Tax Ordinance must be amended accordingly.
The full press release is available here, the ordinance here and the explanatory notes on the amendment to the ordinance here.
