Swiss Cross-Border Worker Diagnostic
France–Switzerland | Basel | Geneva | Jura | Neuchâtel | Tax matters | Remote work | 2041-AS | Swiss withholding tax
Do you live in France and work in Switzerland?
Before validating a tax return, replying to an authority or submitting documents, it is important to check the key points of your situation.
The most common mistakes often concern the 2041-AS certificate, the Swiss salary certificate, Swiss withholding tax, remote work days, non-return days, health insurance, administrative deadlines and supporting documents to keep.
KM Consulting supports France–Switzerland cross-border workers, particularly in the regions of Basel, Geneva, Jura, Neuchâtel and other Swiss cantons depending on the situation.
The objective is to help you understand your situation, identify the main risks, organise your documents and prepare the next steps in a structured and confidential way.
