Just seen this is coming in from 1st January.
" CROSS-BORDER WORKERS : At the beginning of 2025, a legal basis will come into force in Switzerland for the taxation of cross-border workers’ income when they work from home. The basis will thus be created to allow cross-border workers to be taxed even if they telework abroad. As a rule, income is taxed in the country where you work. If cross-border workers switch to the home office, their income would therefore be taxed in the country where they live. The changes are limited to Switzerland’s five neighbouring countries. Cross-border workers in France can now work from home for up to 40% of their working time, in Italy, the threshold is 25%."
Does that mean they could be taxed in their home country and in Switzerland too if working from home?
