Executive Summary
The State Secretariat for International Financial Questions (SIF) announced on May 1, 2026, that Switzerland and France concluded a new mutual agreement on May 29, 2026, regarding the taxation of cross-border telework. The agreement is based on the supplementary protocol of June 27, 2023, to the bilateral double taxation treaty, which entered into force on July 24, 2025, and has been applicable since January 1, 2026. The content corresponds to an earlier agreement of June 30, 2023, but has been adapted to the new legal framework. The information sheet with application examples has also been updated.

The telework taxation regulation is gaining in relevance, as remote work has become structurally established since the pandemic and shapes the economy in border regions such as Geneva–Savoy or Basel–Alsace. With applicability since January 2026, the two countries are creating legal clarity for tens of thousands of cross-border commuters who work partially from home. The updated agreement reduces double taxation risks and strengthens planning certainty for employers and employees in the border region.
Detailed Summary
The supplementary protocol of June 2023 clarifies how income from telework is to be divided between Switzerland and France. The core of the regulation is the permanent establishment principle adjustment: employees who work partially from home are not automatically considered a permanent establishment of the employer in the neighboring country. Instead, a threshold is defined – typically 40% of working days abroad – above which increased taxation rights apply.
The new mutual agreement of April 2026 transfers these principles to the legal framework applicable since January 2026. The updated information sheet with concrete calculation examples enables taxpayers to assess their individual situation. Particularly relevant for border regions: the regulation prevents cross-border commuters with home office shares from being fully taxed in both countries, which secures the competitiveness of Swiss and French companies.
Key Statements
- Switzerland and France uniformly regulate taxation of cross-border telework
- Legal basis: supplementary protocol of June 2023, applicable since January 2026
- Practical clarity through updated information sheet with application examples
- Reduction of double taxation risks for cross-border commuters and employers
Critical Questions
Evidence & Data Quality: What empirical data on telework frequency in the border region underpin the 40% threshold? Were employer associations or employee representatives involved in setting the threshold?
Conflicts of Interest: Does the regulation favor employers more (avoidance of permanent establishment status) or employees (taxation at place of residence)? How were diverging interests balanced?
Causality & Alternatives: Why was the June 2023 agreement not applied directly from July 2025, but only from January 2026? Were there technical or administrative obstacles?
Feasibility & Risks: How do tax authorities monitor the actual distribution of working days (home office vs. office)? What documentation obligations apply to employees and employers?
Practical Impact: How many cross-border commuters are affected by the regulation, and what tax savings are realistically to be expected?
