The cadastral value is the administrative value that the Cadastre assigned to a property and which serves as the basis for calculating taxes and fiscal obligations linked to that property. It is used for tax purposes (e.g. IBI) and is determined by applying technical criteria and official coefficients, so it is not equivalent to a market price.

The calculation of the cadastral value is based on technical criteria and official modules. Without entering into complex formulas, the cadastral value is constructed from:
- Cadastral value of the land. It depends on the location, planning and parameters of the municipality, among others.
- Value of construction. It considers characteristics such as construction quality, surface area, use of the building and other cadastral criteria.
- Coefficients and municipal/appraisal criteria. They adjust the result according to the zones, typologies and criteria approved in the value report.
- Age, use and condition (according to Cadastre). Age and use influence the administrative valuation of the building.
In short: the cadastral value of a property is usually an adjusted sum of land + building, modulated by official coefficients and valuation criteria.

Cadastral value, taxes and taxation
The cadastral value is closely linked to taxation, especially because of its role in the IBI and cadastral value.
- IBI: is calculated by applying the tax rate on the cadastral value.
- Municipal capital gains tax (IIVTNU): on Cadastre and the value of the land may be indirectly related, depending on the applicable regulations and calculations.
- Transfers, inheritance and donations: The cadastral reference value (from 2022) is used as the taxable amount in the case of ITP and ISyD in second-hand housing, taxed at the reference value unless the deeded value is higher.
Selling below the cadastral value: what does it mean?
Selling below the cadastral value and sale price is not, in itself, a “problem”. The relevant tax issue usually comes from:
- How the tax base is determined (e.g. reference value in ITP/ISyD), and
- How discrepancies are justified if the administration considers that the declared value does not comply with the applicable framework.
If there are relevant differences between administrative values and the reality of the property, it makes sense to document the transaction well.

- Inheritance and donations (deliveries, technical support).
- Financing / mortgage (official valuation).
- Divorces and court proceedings (objective assessment).
