Hi there! Sorry, this is probably an overanswered question, but it's still not very clear to me if I release a game, then regardless of the my geographic position do I have to compile USA taxes? From what I understood, once you release a game 30% of your income would go to  the VAT, but does this mean I have to compile foreign tax documentation? Does the Collected by itch.io (Payouts) means that it's itch.io that takes care of this part?

 I'm a student, I don't have an income to declare because I don't have a job, would I need to register as a professional freelancer If I wanted to compile the tax form in my country (Italy)? And If I start earnining from a game ( a big BIIIIIG IF) and start paying the VAT, do I have to continue paying it or is it only if I earn something? 

Sorry for the broken english and probably repetitive question

Have a nice day! :)
