On 13 January 2022, the Federal Council announced that it would like to implement the agreed minimum tax for certain companies with a constitutional amendment. A temporary ordinance is to ensure that this can come into force on 01 January 2024. Subsequently, the law will be enacted through the ordinary legislative process.
The minimum taxation applies to internationally active companies with turnovers of more than 750 million euros. If a country maintains low taxes, this allows other countries to tax the under-taxed companies additionally. By adopting these rules, Switzerland ensures that it does not give away any tax revenue it is entitled to.
