I am Italian and I will move to Sio in May and I have a few questions:
1) I invest with DEGIRO buying ETFs, do I have to declare the amount of my investments every year?
2) I read around that even if ETFs are accumulative in Switzerland you still have to pay dividends as if they were distributed, is that right? How do you calculate them?
3) Do I have to declare my Italian bank account somewhere?
thank you very much for any answers
3) Do I have to declare my Italian bank account somewhere? Yes, your world wide income/assets.
So I have to file a tax return?
I read that those who have a dependant job and do not exceed a certain amount of money should not make a tax return.
in this case, even if I don’t exceed the annual threshold, I still have to do it because I have investments, right? how much does the tax return cost?
That's correct. The simplest version is that your ETFs are in https://www.ictax.admin.ch/extern/en.html# system, then it will take care of it for you, otherwise it probably will require some work to do (I never had to do it manually).
There is no difference which country your bank/broker is located in, for Swiss taxes
Under certain conditions when you are paying taxes at source and you earn less than X you are allowed not to file a tax return, yes. Just the fact of having investments does not mean you automatically have to do it in that case. But keep in mind that there are also other conditions where a tax return becomes mandatory, for example when your total wealth goes above a certain limit - you should check the rules for your canton specifically
It is very doable to just do the taxes yourself in Switzerland. Otherwise, for a "simple case" you can get away with something as low as 100chf
