Hello to all,I am new here so please

Hello to all,

I am new here so please forgive my ignorance. My question is about self employment in Italy. I am a freelancer in the Uk and I work in the events industry. I am moving now in Italy and need to know the procedures in order to be self emplyed in Italy and if really does it worth it or not. I heard some stories about 57% taxes ??!!! I hope not...

Thank you 

V.
