I moved to Italy in 2021 and got into the Impatriati regime (90% tax exemption).
I got an accountant, and ever since pay him €4000 per year. In 2021 he opened a Ditta Individuale for my online business.
He said that for the invoices, if my clients were not from Italy, I could issue PDF...
Jokers. I guess its a cash grab as desperate UK non-doms start considering Italy. I guess they would not increase if they feel non-doms would not pay. This is all UK government had to do (charge 200k) rather than abolish non-dom scheme...lol...
