I'm Italian too, and I came to this thread to make the same comment. Stay away. Running your business in our country, given the taxation laws and other stupid draconian regulations, it would just be crazy.
In 2014 the rate of failing companies was 2 per hour. And we are not talking about just startups here, which have a high burn rate. Many companies that have managed to survive for years have been killed by changes in the regulations during the last years.
For example, in recent years a stupid regulation called "sector studies" have been introduced. Basically, they look at the average you should be earning in a specific field. If you report less than that amount in a tax declaration, you are assumed to be evading taxes. Practically you are assumed guilty until proven innocent, which is not as easy to do as you think.
This is without adding other systemic diseases. Having a tax check is not a desirable outcome in Italy. One anecdote from a friend: he got a tax inspection in his company (in the construction sector). After two days of checks, nothing was found. But instead of being left alone, the inspectors told him this: "we haven't found anything, but since we have been checking for two days, we have to find something". In the end they agreed on faking some irregularities on the heating system and a 500€ fine.
Yes, this is just one episode, but not really an uncommon one, unfortunately.
I left my country 5 years ago and never looked back. There are so many better places in Europe, I strongly advice not to start a company in Italy.
