I always wondered if abroad workers working for a company located in Switzerland still pay taxes to Switzerland or the other country in which they reside.

Normally if you are resident in a country, you pay your taxes at your point of residence.

And what about pension, AHV and stuff like that?

You just pay into the local social system of your country of residence.

Which country are you thinking of, what is your nationality, I am not sure whether you can pay into the Swiss social system as voluntary contributions, but if applicable it would only be for Swiss Nationals at a guess.

Italian nationality.
My company accountant told me that social security is to be paid where the company is, so i'd be paying that to Switzerland providence even if I reside abroad because I'd still be working remotely for a Swiss company. What I can get is just the bare bone taxes, but i will need to pay them in the residence country.

Anyway living out of Switzerland with Swiss social security isn't that bad, I may consider the option.
So the conclusion is that taxes are paid where you reside and social security contribution are paid where the company is, it doesn't sound complicate in the end, indeed it sounds rather logic and convenient. Another valuable information to record in this forum .

Thanks.
