SPID
Also known as: digital identity, Sistema Pubblico di Identità Digitale
SPID is Italy's public digital identity system, used to log in to the Agenzia delle Entrate, INPS, and most public services online. It's issued by accredited private providers after identity verification.1
What this means for you
It's the practical key to managing your taxes online — but it's a known barrier for foreigners: obtaining SPID typically requires an Italian ID document and a registered residence, which non-residents often don't yet have. A workaround is eIDAS or a provider that accepts a passport + codice fiscale.
