I recently had a conversation with a collegue and we didn't conclude if we need to do something when moving to switzerland, to avoid being taxed by both countries
For instance, I came from Spain a couple of months ago, and stopped working there, and got a salary in Switzerland. I'm gonna pay taxes here in Swiss, but should I do something else to inform the spanish government that I'm here to avoid problems later? As far as the government is concerned, I'm still there, but of course I'm not gaining any more money (not employed)
