This depends:

- Was CGT paid in the UK? or was this you sole residence sold to move here?
- Have you previously shown the property on your Swiss tax form? If so does it actually show a gain on sale??

My experience is that the Swiss local tax office and the Notariat (legal department when buying/selling a property) work very closely on sales here. However, your Swiss tax office will only be informed by you of a sale in the UK.

Obviously if you shift the capital over here, the Swiss tax man will need to know from whence this came. You should be declaring your world-wide assets.

I certainly did not declare any gain, nor was I asked, I just declared the value...
