The Spanish Tax Agency (AEAT) announced that during a targeted campaign it carried out 1,329 tax inspections focused on high‑net‑worth individuals. The inspections, which spanned across various sectors including personal wealth, assets and offshore holdings, resulted in the recovery of 547 million euros. The operation underscores the agency’s intensified effort to combat tax evasion among the wealthiest taxpayers, employing advanced data‑analysis techniques and cross‑border cooperation. According to the press release, the inspections were designed to scrutinise declarations that presented significant risk indicators, such as large unexplained expenditures, ownership of luxury assets and participation in complex financial structures. Findings indicated that many of the examined returns contained undeclared income or concealed assets, leading to additional tax liabilities, penalties and interest. The AEAT highlighted that the revenue generated from these inspections not only reinforces public finances but also serves as a deterrent against future non‑compliance. The agency also emphasized its commitment to transparency and to supporting honest taxpayers, noting that the campaign aligns with broader European Union initiatives aimed at curbing tax avoidance among affluent groups. The campaign, which took place in the first half of 2026, leveraged sophisticated audit tools, including data mining and risk‑scoring algorithms, to identify patterns of non‑declaration. The agency also stepped up coordination with international tax authorities to exchange information on assets held abroad. This coordinated approach allowed the AEAT to target not only domestic wealth but also to follow money trails that extend to foreign jurisdictions.
