How the taxation works
Residents of Waldshut-Tiengen working as cross-border commuters in Switzerland are taxed under §15a of the Germany-Switzerland treaty: the Swiss employer withholds 4.5% of gross pay at source, provided the worker files a residence certificate (Ansässigkeitsbescheinigung). Germany avoids double taxation via a tax credit (credit method) for the amount withheld in Switzerland. The regime applies across the whole territory, with no border-strip geographic restriction.
Non-return days: the 60-day threshold
Cross-border status is lost for the ENTIRE fiscal year if you exceed 60 non-return working days. For part-time work the threshold is proportional: 5 days per month worked plus 1 day per week worked. Homeoffice days do NOT count as non-return days.
Health insurance: the opt-out right
A cross-border worker can opt out of compulsory Swiss health insurance to stay in the German system (Optionsrecht, legal basis Art. 2 para. 6 OAMal). The choice must be made explicitly within 3 months of starting work: tacit exercise is not valid, and the choice is generally irrevocable once made.
