@c4ccheyenne That’s really tricky because actually you would need to declare the account end of the year, for this year.
Informations are automatically transfered to swiss authorities.
Any transfer of >9.999.- to switzerland can be subject to a financial control.
You should first ensure that you don’t get in any tax difficulty.
Pay attention to withdrawl limits, CH Banks are usually 1% from 50.000.- or 3 months waiting time.
You risk to have to withdraw earlier when you move back.
Also no idea on possible taxes once you wire it again to italy.
