I have been a stay-at-home mum for a while (officially: unemployed) and now started working as a freelancer. I had mentioned that I was planning on doing this to the tax officials at some point earlier already and thus received a freelancer tax card for this year.
Now, how exactly do I pay my taxes? Payments come from different sources, so do I just forward all my bills and earning statements from the various clients to Vero?

I read about toiminimi and other business forms all the time, but back when I talked about the freelancing at the Vero-office, I was told I don't need to set up any kind of business if working on the freelancer tax card. So...eh? I have never had to do this kind of stuff before, so excuse me for being stupid. :/
