Hello!

First, this site is fantastic resource, so much information. I have looked through sticky topics but sorry if I missed this subject being covered already.

I'm a Europe citizen, working in Geneva canton fulltime at big company. I live in Geneva and have a B (CE/AELE) permit. I pay tax at source on my main salary.

I've lately made a website in my spare time, which makes some money from adverts.

How should I declare this income? What impact will it have? Am I doing anything wrong with my work permit?

Thanks in advance for your thoughts!
Y
