Hi folks, hope you are all well and can help me with my question.
It concerns my car which I brought with me when I first moved to Switzerland in May last year. It has an EU plate, I declared it at the boarder and got the 13.20A form which allows me to drive the car until April 2020.

Now, I've decided that the best option for me is to buy a new car in CH and bring back the one I have to sell it in my country.

My question is, do I just need to stop at the board while driving out to cancel the 13.20A form? Or is there other steps I need to follow? I'm planning to drive the car off CH by mid april.

Thank you for the help!

25 years ago I was in the same situation, I stopped at the border & they had no interest in the matter.

The form is simply proof that you brought the car into the country, and officially declared it, on a given date. It's for you to use if you want to register the car here, but no-one cares whether you do so or not.

So no, nothing for you to do, just as long as the car is no longer here.

I declared my UK Car out of the country when I left to sell it. Just for peace of mind I got a form signed and stamped stating this. I prob didn’t need to do this, most info states you don’t but then most info is by expats. The Swiss love their paper work so best to cover all bases. I’ll try and dig up which form it was.

I had the same situation.

Emailed Zurich customs department, with a scan of the form.

Two days later, I got an email confirmation that the temporary import had been cancelled and the car was out of their system.

I'm guessing you didn't declare the car as permanently exported in your home country.

Thx for the tips, I agree that even when not needed the best is to ask for a signed paper where it clear mentions the car is not anymore in the country and then mail it to the traffic authorities from my canton.
My concerns came from the fact I recently received at home a letter telling me I had until end of April to change the car plates, I was afraid if I didn't do that they could send me a second letter with a fine, are you sure they wouldn't do that?

No, I didn't declare anything in my country as by the time I came for CH I wasn't sure what I would like to do with the car..
