Catastro (Cadastral Registry)
Catastro (Cadastral Registry) — The Catastro (Cadastral Registry) is Spain’s comprehensive inventory of all real estate, maintained by the Ministry of Finance. It records the physical characteristics of every property — location, boundaries, area, use, and the cadastral value (valor catastral) — which forms the basis for calculating property taxes such as IBI.
While the Registro de la Propiedad (Land Registry) deals with legal ownership and charges, the Catastro is concerned with physical reality and tax assessment. Every property in Spain has a unique 20-digit cadastral reference number that identifies it. The cadastral value is set by the Catastro and is typically lower than the market value — it is used to calculate IBI (council tax), plusvalía (municipal capital gains), and forms part of the basis for various other taxes.
Catastro vs Land Registry — Why Both Matter
One of the most common problems in Spanish property transactions is a discrepancy between what the Catastro says and what the Land Registry says. The Catastro might show a plot of 120 m² while the escritura says 150 m². Or the Catastro might not reflect a garage or extension that was built without a licence. These discrepancies must be resolved before purchase to avoid problems with the notary, the bank (if you need a mortgage), and future resale. Your lawyer should compare both records as part of the due diligence process.
