Another question may arise: Do I need to open a Partita IVA to work as a self-employed person?
The answer is that You don’t need a Partita IVA if your job is not running regularly.
In this case, your job is regulated as “Temporary job” (lavoro occasionale).
You may have heard that You can work on a Temporary Job / lavoro occasionale only until € 5.000 per year. This is not true, because the 5.000€ ceiling has been canceled a few years ago, so now the only criteria to work without P.IVA is only “qualitative”.
You must remember, however, that when you exceed 4.800€ over the year, you must inform your Employer, that will pay your social security contribution on your behalf as "sostituto d'imposta".and transfer you the net amount.
