Anticipated Impact of Global Minimum Tax: Switzerland Poised to Gain USD 600 Million

August 14, 20230


The imminent introduction of the global minimum tax is poised to usher in substantial fiscal changes for Switzerland’s cantons. A recent report by the Swiss Federal Department of Finance sheds light on the anticipated financial implications of the Organization for Economic Co-operation and Development (OECD) minimum tax on the cantonal level. This article delves into the report’s findings, highlighting the projected effects of the global minimum tax and the measures the cantons are planning to adopt.  


Swiss Cantons Brace for Change  

Drawing from a comprehensive survey conducted among the cantons as of May 31, 2023, the report offers a comprehensive outlook on the impending shift in Switzerland’s taxation landscape. The survey underscores the cantons’ proactive stance toward the forthcoming OECD minimum tax and their concurrent efforts to enhance their competitive edge.  


Collective Cantonal Approach  

The report reveals a unanimous commitment among all cantons to address the challenges presented by the proposed global minimum tax. Their dedication is underscored by the strategic consideration of measures aimed at reinforcing their respective locational attractiveness. Crucially, it is within the scope of the cantons themselves to implement the global minimum tax, thereby allowing for a cohesive response across the Swiss administrative landscape.  


Projected Financial Boost  

Notably, the report discloses that approximately half of the cantons, while anticipated to generate substantial supplemental tax receipts, have yet to formulate their own estimates. By consolidating the estimates provided by the remaining 13 cantons, the supplementary tax receipts, including the federal share, are projected to surpass CHF 500 million (equivalent to USD 600 million).  


Strategic Diversity Among Cantons  

Intriguingly, the survey unveils a spectrum of approaches embraced by the cantons. Some cantons have opted to maintain their current corporate taxation structure without necessitating adjustments or other supplementary measures. For certain cantons, as of the reporting date, the specific adjustments to be implemented remained undetermined.  

Conversely, several cantons have embarked on a proactive path by either considering modifications to their corporate taxation policies or by strategizing the utilization of funds derived from the supplementary tax. However, the depth of these discussions varies across the cantonal landscape, with some cantons still in the preliminary stages of deliberation.  



Switzerland’s proactive response to the anticipated implementation of the global minimum tax underscores its commitment to maintaining a resilient and competitive economic environment. As the cantons navigate the evolving tax landscape, the report’s insights provide a comprehensive understanding of the impending fiscal adjustments. For tax professionals, investors, and businesses vested in Switzerland’s financial scene, these findings serve as a crucial touchstone for informed decision-making and strategic planning amidst a dynamic global tax paradigm.
