We will be leaving Switzerland in a few months time and I wondered what we are supposed to do with our permits (Permit B) when we leave? Do we need to go and deregister at the police station or send our permit somewhere? We live in Zurich.
Thanks!

No, you need to deregister with your gemeinde admin office. They'll give you a document you can use to cancel things like the phone, mobile phone, insurances, etc.

This is very useful to know. Thanks for sharing.

Cheers.

I deregistered, however I did not have to hand in a C permit with 3 years left to run. I was quite surprised, they only wanted money in CASH for a possible tax liability, this money & more was refunded 3 months later after I had completed a tax return for my departure year.
