My Swiss citizenship came through in March (roughly 1.75 years start to finish). I recently went to a mobile phone shop to change my mobile subscription, and as I did, the salesperson asked for an Ausweis. When I gave her my new identity card, she said I should have notified the phone company of the change from the previous C permit. That made me wonder whether I should be providing the change in status to the AHV, health insurance, tax authorities and so forth. Aside from instructions about registering to get my passport, all my correspondence from the various levels of government said only "congratulations," nothing about notifying anybody.

Have any of you who have been naturalized let various authorities know?

Tax authorities will know by themselves. If you had permit C not much will change in this regard anyway.
More important is HR. And what can save you some money is your car insurance.

Is there a difference between c and b on the car insurance front?

Yes. The insurance companies are the ones to inform. You could get a few discounts.

The phone company ? They are just being noisy.

There is a difference based on nationality. I didn't see a difference with change of permit. That quite possible as well though.

I do not know. But there is certainly a difference in the nationality front.
For ex. on the Zurich online application form https://www.zurich.ch/de/praemienrechner/auto you can only select nationality but not permit type.

I think with Axa I had to enter permit, so will give my man a call before renewal..always worth a try

You will need a new DRIVING LICENSE and GREY CARD for the car(s) since your nationality is printed on them.

It is normally done quickly (at least in VD), just the time to print up the new ones (you will need proof of CH citizenship) and for you to pay of course.

Banks, license, registrations, insurances, and employer.

Tax and municipal authorities will know on their own.

Maybe don't assume that Swiss nationality = cheaper... given how the Swiss seem to insure everything, twice, I wouldn't be surprised if insurance is more expensive!

If you ended up with dual nationality, I don't see any reason why you must tell an insurer about the Swiss one, since the other is still valid, unless they explicitely ask for all nationalities (which I don't recall ever seeing).

You could do an online quote to see if there's a difference before you tell them.

Edit: and I wouldn't be surprised if they charge you for updating the details, even if the premium doesn't change!

Seems overkill, no? how would anyone know?

If you are Swiss, the other nationality is NOT valid in Switzerland!

Why, from a contractual viewpoint, which is what this is?

Having Swiss nationality in Switzerland means you cannot claim foreign nationality to avoid any responsibilities, and you can't claim foreign rights here.

Nowhere does it say (afaik) "you can't use your other nationality for anything within Switzerland" - but please correct me if I'm wrong.

A problem could be that when travelling you have to choose which nationality you use, you cannot switch and take the rights/benefits which fits the occasion the most. So entering as a Swiss in for example Germany, but using Greek nationality for your allowance to drive might give complications in some situations.

I am not certain about this, but like to have my papers saying the same thing.

I think we had this discussion before and as far as I know there is no single article in Swiss law which would forbid it, including entering the country, in any kind.

So, you get pulled over, cop sees foreign nationality listed, and asks to see your permit.

What then?

Tom

Actually my insurance called me when they saw I had two nationalities to let me know that I could get a cheaper rate with one over the other.

I signed up for insurance using the nationality of the country I got my license.

They did in fact ask for the permit which is were they saw I had a different nationality.

The insurance for the nationality on the permit was less than the one I signed up with. That was a nice surprise.

So it might not be a bad idea to tell them all your nationalities, or as you write check online.

At least something very similar, indeed. It was in the thread on entering CH without your residence permit on you. On that occasion I wrote to SEM to ask, but couldn't get a clear answer for what would happen if a dual-national uses his foreign nationality upon entering. It was as if that option didn't exist - and perhaps it actually doesn't, from a legal point of view.

I think it's like this:
It doesn't matter if you use a foreign nationality or not, the fact of your Swiss citizenship remains. So once the authorities become aware of your Swiss citizenship that's the only thing that will be taken into account. Private dealings and contracts are a completely different thing of course.

My AXA car insurance policies went down when I advised them of my Swiss Nationality.

You show him your "Permit CH" a.k.a Swiss ID.
It is like having multiple places of origin.
