Switzerland-France cross-border telework: new employer reporting obligations land
The transitional Switzerland-France cross-border telework agreement ended on 31 December 2025, and the new permanent reporting regime is now in force from 1 January 2026. Swiss employers must now report to Swiss tax authorities, for every employee teleworking from France: the employee’s name, the calendar year, the number of telework days, and the gross salary corresponding to those telework days. The first wave of practical compliance burden lands across spring 2026 as employers complete the reporting cycle for the first full year.
Why this matters. The Switzerland-France cross-border corridor is one of Europe’s largest single-country remote-work population — tens of thousands of workers live in France and work for Swiss employers, frequently with significant telework from the French side. The transitional agreement made this easy by treating cross-border telework as tax-neutral up to a generous threshold. The new permanent regime keeps cross-border telework legal but requires Swiss employers to track and report it precisely, with implications for both Swiss and French tax filings.
For Swiss employers with French-resident remote workers, the practical lift is now real: HRIS systems need to record telework days at country-level granularity; payroll teams need to allocate salary to those days; and reporting workflows need to push the data to Swiss tax authorities annually. Smaller Swiss employers without dedicated international-payroll capacity may find this prohibitive and could pull back from cross-border arrangements. For French-resident workers at Swiss employers, the new regime makes telework legally tidy but practically more visible to both tax authorities.
What to watch. The Switzerland-France regime is the first major bilateral cross-border telework framework to move from “transitional” to “permanent enforcement” in Europe. Similar bilateral arrangements (Switzerland-Germany, France-Belgium, France-Luxembourg) are at various stages of formalisation. The Swiss model will likely become a template — track these as the next 12-18 months bring more bilateral agreements into permanent compliance regimes.
