The Federal Central Tax Office describes an internet crawler, Xpider, that searches for persons and businesses offering goods and services online and reports finds to the Länder tax authorities. The tool dates from 2003 and the page carries no freshness date; the most recent independent corroboration of active use is from 2020, so continued operation is not confirmed. Open-web monitoring of commercial activity; no source establishes monitoring of individuals social-media posts.
“Eine intelligente Suchmaschine mit Namen Xpider sucht im Internet nach Personen und Unternehmen, die dort Waren und Dienstleistungen anbieten. Entsprechende Funde werden regelmäßig gesammelt den Landesfinanzbehörden mitgeteilt.”

Inland Revenue states it collects personal information that is publicly available on open-source websites and public registers. The two examples it gives are an online-marketplace search to establish whether someone is in business, and a social-media search to locate individuals who already owe tax — the latter being collection tracing rather than income detection.
“Examples include a Trade Me search to find out if you're in business, or searching social media to find individuals who owe tax.”

The 2026 tax control plan (BOE) gives preferential enforcement attention to business models built on social networks — influencer marketing gets its own section (A.5.4) — but this targets social-media businesses rather than general monitoring of taxpayers’ accounts.

🇺🇸United States Partial / committed
The Internal Revenue Manual authorises — but does not itself document actual use of — employee searches of publicly available internet and social-media information for compliance work, research it says may include identifying other possible unreported sources of income.
“IRS employees are allowed to search for publicly available information on the internet, which may include publicly available social media information, to perform compliance-related work. Compliance-related research may include locating taxpayers, identifying assets subject to seizure or levy actions, and identifying other possible unreported sources of income.”

🇮🇹Italy No — power absent
The Agenzia delle Entrate officially denies any mass collection of social network data, stating Italian law does not permit acquiring data from social networks by such procedures and no such initiative has ever been adopted (May 2026 statement; Law 132/2025 also bars AI-generated administrative acts).
