We Review the Cadastral Reference Value
When buying or inheriting a property in Spain, understanding the Cadastral Reference Value is crucial. This valuation method, imposed by the Tax Agency, often determines the tax base for property transactions. While it is typically lower than the purchase price in most real estate transactions, there are cases where the market price falls below this value. Our goal is to ensure you pay only what is fair and necessary, avoiding overpayment and ensuring compliance with Spanish tax laws.
Understanding and Navigating Spanish Property Taxes
Navigating Spanish property tax can be a daunting task for buyers and sellers alike. Since 2022, the tax base for property transfer tax (ITP) and inheritance and gift tax (ISD) is determined by the property’s ‘reference value’ as set by the Cadastre. This value, which may not reflect the actual market price, can lead to overpayment of taxes if not properly managed. Our expert legal team is here to ensure you pay the correct amount and that your property transaction is both fair and compliant.
What is a Reference Value (Catastral)?
The Cadastral Reference Value is an administrative valuation of a property, determined annually by the General Directorate of Cadastre. It serves as the minimum tax base for property-related taxes, such as transfer tax, inheritance tax, and gift tax. It is important to note that this value is distinct from the cadastral value used for local property taxes like IBI.
- When the purchase price is higher than the reference value: Taxes are calculated based on the purchase price or market value.
- When the purchase price is lower than the reference value: Taxes are calculated based on the higher reference value, potentially resulting in overpayment.
For rustic constructions on non-developable land and new constructions, there is no cadastral reference value. In these cases, our team will advise you on the appropriate value to declare, ensuring you pay taxes based on the purchase price or market value.
Why Check the Cadastral Reference Value?
Before buying or inheriting a property in Spain, it is essential to check the Cadastral Reference Value. This ensures you understand the taxes you will pay and whether it is necessary to conduct a valuation or challenge the reference value. By doing so, you can avoid overpaying and ensure your tax obligations are accurate and fair.

Our Reference Value Services
We provide comprehensive legal support to challenge and manage the Cadastral Reference Value, ensuring your tax obligations are accurate and fair.
Reference Value (Catastral) Calculation
Our first step is to obtain and analyse the official reference value for your property. We scrutinise the data used by the Cadastre to determine its accuracy and relevance to your specific property, identifying any discrepancies that could form the basis of a challenge.


Tax Compliance
We guide you through every stage of the tax payment process, ensuring full compliance with Spanish law. We will help you understand whether it is more advantageous to pay tax based on the reference value and then appeal, or to challenge the value from the outset.
Property Tax Optimisation
Our primary goal is to minimise your tax burden. We specialise in preparing and filing robust appeals against inflated reference values. By presenting strong evidence, such as independent valuations and detailed market analysis, we work to align the taxable value with the true market value of your property.


Property Valuation
To successfully challenge a reference value, a certified property valuation is essential. We collaborate with accredited architects and surveyors to produce detailed valuation reports that serve as critical evidence in your appeal against the tax authorities.
