International tax agreements
Switzerland has concluded numerous double taxation agreements to prevent income or assets from being taxed more than once. In addition, information exchange agreements allow tax-relevant data to be exchanged between countries.
These agreements promote transparency and support compliance with tax rules in cross-border activities.
Current developments, digitalization and case law
Two developments have shaped Swiss tax law since 2024. First, higher VAT rates have applied since 1 January 2024: 8.1% standard rate, 2.6% reduced rate and 3.8% special rate for accommodation. Second, Switzerland has levied a national top-up tax since 1 January 2024 and an international top-up tax since 1 January 2025, so that corporate groups with annual revenue of EUR 750 million or more pay at least 15% tax. The constitutional basis is Art. 129a of the Federal Constitution (BV), which the people and the cantons approved on 18 June 2023.
The direct federal tax is governed by the DBG, the cantonal income and profit taxes by the StHG together with the cantonal tax laws, and VAT by the MWSTG. Digitalization is increasingly influencing tax collection, administration and planning. At the same time, case law plays a central role in interpreting and developing the tax laws.
Court decisions create clarity and legal certainty on complex questions of tax law.
