Telework calculator for cross-border commuters
Since 2024, cross-border commuters from Italy may work from home for up to 25 % of their working time without any change to taxation or status. Mark your days at home, half days, business trips and absences in the calendar: the tool counts the hours of the whole year, shows your telework share, how many days are left within 25 % and the 49.9 % social insurance threshold. At the end you download the summary as a PDF for your employer.
- Telework share in hours over the calendar year, as the protocol says
- Days still possible within 25 %
- Half days, business trips without returning home (45 days) and absences
- Ticino public holidays already excluded, working days of your choice
- 49.9 % threshold and A1 certificate for social insurance
- Yearly summary as a PDF with the dates and signatures

Frequently asked questions
How many telework days can a cross-border commuter work? +
Up to 25 % of the year's working time. With 5 days a week and about 250 working days that is about 62 days, a little more than one a week; with fewer working days or different hours the number changes. The tool calculates it from your calendar.
Is the 25 % counted in days or hours? +
The protocol refers to working time, not days. If you always work the same hours a day the result is the same; with different hours, time is what counts. That is why the tool calculates on hours and also shows the share in days when it differs.
Do vacation, sick leave and public holidays count? +
No: they are not working time, so they count neither as working time nor as telework. Mark them as Absent; Ticino public holidays are already excluded.
What happens if I go over 25 %? +
The protocol no longer covers all your days at home: the tax consequences depend on your situation and should be checked with the tax authority or an adviser. For social insurance, between 25 and 49.9 % you stay insured in Switzerland only with an A1 certificate requested by your employer.
Does it also apply to old cross-border commuters? +
Yes: the 25 % limit applies to all cross-border commuters under the agreement, including those under the transitional regime. Telework must be done at home, in the country of residence.
Indicative calculation, provided as is: it is not tax advice. Rules of the telework protocol in force since 9 February 2026 and of the social insurance framework agreement.
