We know that the real estate market plays a fundamental role in the current economy, which is why the correct valuation of properties becomes a fundamental aspect for sellers, buyers, investors, and government entities. The cadastral reference value is one of the most relevant tools in this field. This value, which has gained particular importance in recent years, influences real estate transactions and also has a significant impact on urban planning and the tax sphere. Let's look at the key points on this topic to understand it in depth.

In Spain, the reference value cadastral is the minimum that must be paid when acquiring or inheriting a property. This value does not always coincide with the taxable base, because if the declared value is higher, tax must be paid on the latter. This administrative value was implemented in January 2022 and is determined annually by the General Directorate of the Cadastre, based on the cadastral information of the property and, mainly, on the prices of property transfers reported by notaries and other public officials. It serves as a reference for calculating inheritance taxes and donations (ISD), and is also fundamental for calculating taxes on Property Transfer Tax (ITP) and Stamp Duty (AJD).
It's important to note that it can never exceed the market value. To do this, a reduction factor will be applied in its determination. This value is publicly available for consultation on the Cadastre's Electronic Headquarters, but only the cadastral owner has access to the certificate explaining the calculation of the reference value.
Although the traditional cadastral value takes into account various factors such as location, area, use, and property characteristics, the cadastral reference value focuses more on the current market context.
The cadastral reference value serves multiple functions:
This value is used for calculating taxes associated with the transfer of real estate, such as the Property Transfer Tax (ITP) and Wealth Tax.
Provides information for the calculation of traditional cadastral value.
It provides an initial reference for parties involved in a sale and purchase transaction, facilitating informed decision-making.
It helps the Tax Agency detect potential fraud or discrepancies in valuations made by taxpayers.
By guiding the sale price of a property (reference value), it promotes transparency in the real estate sector.
To find out a property's cadastral reference value, interested parties have several options:
The cadastral reference value is determined by the General Directorate of the Cadastre, an entity under the Ministry of Finance in Spain. This calculation is performed by taking into account a series of factors, which includes the analysis of property sales transaction data in the area, as well as the specific characteristics of each property.
The reference value of properties will be determined annually by applying average value modules. To calculate the cadastral reference value, a methodology involving an exhaustive analysis of various parameters is used:
This process can vary depending on local regulations and property type, which adds flexibility but also complexity to the valuation. Understand how this value influences real estate taxes
The cadastral reference value typically varies considerably depending on the property's characteristics and location. For example, in metropolitan areas like Madrid or Barcelona, this value can be much higher than in rural towns. There isn't a fixed percentage, but generally, the reference value is estimated to be between 50% and 70% of the market value, indicating that it is a parameter designed to provide a balanced and fair valuation.
While these two concepts may seem similar to some, there are key differences between cadastral value and market value:
For those looking to maximize their investment or minimize their taxes, understanding this difference is essential.
Let's imagine a single-family home in an urban area of Madrid with the following characteristics:
Let's assume that, after studying various sales transactions in the area, the cadastral reference value for this property is set at 300,000 euros. This means that if the property is sold within that range, both the buyer and the seller must consider this value when calculating taxes associated with the transaction.
In cases where the property lacks a reference value, the law stipulates that the taxable base will be the higher of the following options:
This is the value assigned by the parties when there is no economic consideration, such as in a swap or exchange.
This refers to the amount agreed upon between the buyer and seller in a sale.
This refers to the probable selling price under normal conditions.
If the taxpayer declares a value lower than the market value, the administration may initiate a value verification procedure to prevent fraud, especially if irregularities are detected. Its valuation criteria would be based on the cadastral value and annually updated coefficients.
If a property is acquired for a price lower than the cadastral reference value, there is a risk that the Administration will evaluate the transaction and consider it an attempt to evade taxes; in such cases, it is possible that you may be required to justify the price paid, and the buyer may face a demand to pay the difference corresponding to the Property Transfer Tax.

If a buyer or owner disagrees with the cadastral reference value established for their property, they have the right to file a claim. The reference value can only be challenged when it has a tax effect and is the tax base for Property Transfer Tax (ITP), Stamp Duty (AJD), or Inheritance and Gift Tax.
It is essential to gather all necessary documentation to support your position, such as independent appraisal reports and market comparisons that indicate a different value. This documentation can be submitted to the relevant Administration for review, and an appeal for reconsideration can be filed with the tax authorities.
Although the regulation has not established a precise way to challenge the reference value, there is indeed the possibility to indirectly challenge it when it is believed to harm the legitimate interests of the taxpayer. This occurs when the reference value is higher than the market value.
In this case, the taxpayer must prove that the property's market value is lower than the Cadastre's reference value, meaning that the latter value is incorrect. It should be noted that often, the costs the taxpayer may incur are greater than the debt to be claimed, so it might be more advisable not to claim.
In any case, it is ideal to seek advice from a specialized lawyer or a real estate agent who can guide the process and provide the best recommendation.
