Freelancing in Switzerland

Hi,

I work at a company 80% and I'm thinking of freelancing the remaining 20% to other companies.

How do I go about communicating to local authorities that I am a freelancer?

Since I hold a B permit, my income is taxed at source at my job. How would my freelance income be taxed?

What other taxes should I be aware of?

Thanks in advance

Legally

Fill out a form at the AHV/AVS & pay additional AHV/AVS premiums.

Fill in a tax return.

On the sly

Do the work & say nothing.

Agree with that, once you are in the system, you will be screwed.

Unless you have spoken to the AVH the tax office won't accept any freelance earnings added to my tax return as I discovered.

The Swiss accountant of the company I was working for said I was a fool for saying anything!

Odd this has not been asked before...

Before dealing with all of the above, I would find out if you are allowed to work in any other occupation according to the company's internal regulations. And yes, freelancing counts.

Hey guys.

I searched the forum(and the internet), but couldn't find the answer that could make me happy

So, this is the situation:

My wife has a full time job(100%), as well as myself(100%). We both would like to add some more work on our free time, as a freelancers.

Which is the best way to do this?

We are not planing on working more than couple hours per day, so there is not going to be that much money involved.

I know, someone will say that the best solution is to find clients, do the work, and get money on hands, but I wouldn't like to have some problems with the tax authority later.

Is there a way to just report the money that we earn(which came on our accounts) as additional earnings later on when we fill our tax report?

Or do we need to found a sole ownership for that?
