Hi there

I've been trying to find some information about this on here but with no success. I currently work a 50% job but am looking to possibly increase this by doing some private cleaning work.

Is it possible to have a contract of employment for 50% and still be self-employed for the rest of the time? I know it's possible in the UK and your accountant can simply put in the information on your P60 (annual employment declaration) to your self-assessment form - is this the same in Switzerland?

Some help on the matter would be appreciated!
