Key legal question
Whether the performance income of French artists was taxable in Switzerland under the treaty and domestic source-tax rules
Extracted holding
Yes. The income from the artists’ performance in Switzerland was taxable in Switzerland, and the treaty did not prevent source taxation.
Extracted reasoning
Article 19 CDI-F covers both self-employed and salaried artistic income performed in the source state. The French treaty credit mechanism does not bar Swiss taxation; it only governs relief in France.
