The Spanish Tax Agency launched an anti‑fraud operation across six autonomous communities aimed at curbing tax evasion in the real‑estate sector. The operation, referred to as “Operación …” (the exact name was not disclosed in the press release), involved coordinated inspections of property transactions, registration data and financing arrangements. By focusing on suspicious land‑registry entries, offshore purchases and irregular cash flows, the agency sought to uncover schemes where proceeds from illegal activities were laundered through property deals. The campaign included collaboration with local tax offices, the Ministry of Finance, the Guardia Civil and financial intelligence units, enabling a multidisciplinary approach to detection and prevention. The agency announced that the inspections covered both residential and commercial properties, and that they targeted entities and individuals suspected of using fictitious contracts, inflated valuations and undisclosed beneficial owners. Early findings indicated irregularities in thousands of transactions, prompting corrective tax assessments and referrals for criminal investigation where appropriate. The AEAT also highlighted the importance of modernizing land‑registry data and improving digital reporting to detect fraudulent schemes more efficiently. This operation reflects a broader strategy to reinforce tax compliance in high‑value sectors, protect public revenue and ensure a level playing field for legitimate market participants.
