Is there any official confirmation anywhere that a nomad registered as self-employed (lavoro autonomo) doesn’t pay social security/insurance contributions? Please give at least some link.
That depends on how the status is actually set up — it isn’t that clear-cut. If a partita IVA (VAT number) is opened, there will be contributions to INPS (Italian social security); that’s the standard setup for the self‑employed (autonomo). It’s a different story if nomads on a visa don’t have a partita IVA and work for a foreign employer — in that case, yes, there are no Italian contributions. In short, you definitely can’t sort this out without a commercialista (tax advisor/accountant); there are too many nuances depending on the specific situation.
To be honest, it’s hard to point to a specific law here — the nomad visa (digital nomad visa) is still such a new thing that even commercialisti (Italian accountants/tax advisors) argue among themselves. Lavoro autonomo (self-employment) has been converted for a long time, that’s true, but there’s almost no practice yet for nomads. If I were the author I’d go to a patronato (patronato/worker assistance office) with a specific question; it’s free there and they’ll at least give up-to-date information.
There’s a specific law - DECRETO LEGISLATIVO 25 luglio 1998, n. 286, Article 26 on lavoro autonomo (self‑employment). It spells out the quotas, and nomads were added as an exception — that’s official. But that’s specifically about entry quotas, not about contributions directly. If the activity is regular — you still need a Partita IVA (VAT number), and then contributions to INPS (Italian social security) won’t go away.
Exactly — the decree is about quotas, not contributions; they’re totally different things.
