**On the IBI receipt**, the property tax bill the town hall sends every year: look for **"valor catastral"**. It is the value of the whole home, whatever the number of owners.

- The same receipt shows the **referencia catastral**, the reference that identifies the home on Modelo 210.
- **No receipt at hand?** Open the Sede Electrónica del Catastro (it exists in English), log in with Cl@ve or a digital certificate, and look up your property: it shows the value and gives you a free certificate.
- **No Cl@ve or certificate?** A Punto de Información Catastral, often at the town hall, can give it to you (some charge a fee), or you can write to a Gerencia del Catastro.
- País Vasco and Navarra keep their own cadastres.

## Why it matters

For a home you don't rent out, the tax starts from this value: 1.1% of it if your town's values were revised since 2012, 2% otherwise (rules for tax year 2025). Our [simulator](https://casitatax.com/en/simulator/) shows the year your town last revised them.
