The cadastral reference value has become one of the most relevant tax issues in real estate sales, inheritances, and donations in Spain. Although the Constitutional Court has generally upheld the system, this does not mean that taxpayers must always accept the valuation set by the Cadastre. When the cadastral reference value does not match the actual value of the property, it is still possible to challenge it through the appropriate legal channels.
In Mallorca, where many real estate transactions have a significant tax impact, carefully reviewing this issue can make a big difference. An overvaluation can significantly increase the tax burden for buyers, heirs, and donees. Therefore, it's important to understand what it is, how it works, and in what cases it can be appealed.
What is the cadastral reference value?
The cadastral reference value is an economic magnitude introduced by Law 11/2021. Since January 1, 2022, it acts as the minimum taxable base in taxes related to the transfer of real estate, especially in the Property Transfer Tax and Documented Legal Acts and in the Inheritance and Gift Tax.
This means that if the price recorded in the deed or the declared value is lower than the cadastral reference value, the tax authorities can use the latter as the basis for calculating the tax. In practice, this can result in the taxpayer paying more tax than the actual value of the transaction.
Why it can cause problems
The main problem is that the cadastral reference value does not always reflect the specific circumstances of each property. Although the system is based on objective data, it does not always adequately capture factors that can significantly reduce the real value.
Properties that need renovation
A property in poor condition, with dampness, damage or in need of complete renovation may have a lower market value than that reflected in the Land Registry.
Loads and limitations
Easements, litigation, occupations, urban planning limitations or legal problems can also affect the real value of the property without this being properly reflected.
Difference between administrative valuation and market value
In many cases, the cadastral reference value ends up being higher than the market value. This difference is precisely what can justify a challenge.
The Constitutional Court endorses the system, but does not prevent it from being appealed
The Constitutional Court's ruling has generally upheld the model. However, this does not preclude taxpayers from challenging it. The important point is that it remains possible to demonstrate that, in a specific case, the cadastral reference value does not accurately reflect the property's true value.
What does this mean in practice?
A general challenge to the system is no longer the primary avenue, but individual case review is. Appeals are permitted when the valuation is excessive or technically incorrect.
When might it make sense to challenge
It is not always worthwhile to initiate a procedure, but there are situations in which it is advisable to study it in detail.
When it exceeds the actual market value
If the cadastral reference value is clearly higher than the actual price of the property, there is a reasonable basis for analyzing the viability of the appeal.
When there are unique circumstances
Defects in conservation, legal limitations, charges or specific problems of the property may justify a lower valuation.
When there are errors in the Cadastre
An error in the surface area, age, category or description of the property can directly influence the calculation of the cadastral reference value.
How to calculate
The Cadastre calculates the cadastral reference value based on average value modules for each area, compiled using data from sales formalized before a notary or registered in the Property Registry. Corrective measures are then applied based on the type, age, and other characteristics of the property.
Although the system seeks an objective valuation, it does not always manage to adjust to the specific reality of each property.
How can one appeal?
The procedure depends on the stage the file is at and how the tax was settled.
Correction of self-assessment
If the tax has already been filed using the cadastral reference value, you can request a correction of the self-assessment and, if applicable, a refund of undue payments.
Appeal against administrative settlement
If the Tax Office has already issued a provisional settlement, options such as the appeal for reconsideration, the economic-administrative claim and, where appropriate, the contentious-administrative route can be considered.
Expert evidence is fundamental
To challenge the cadastral reference value with real estate options, the standard procedure is to provide a solid expert report. Simply stating that the value seems high is insufficient. It is necessary to demonstrate, using technical criteria, why it does not correspond to the property's actual value.
A well-structured report can be the most important basis of the appeal.
Special relevance in Mallorca
In Mallorca, the cadastral reference value is of particular importance due to the size of the real estate market and the volume of transactions involving both residents and non-residents. A significant difference between the administrative value and the actual market value can result in much higher taxes.
Therefore, before simply accepting the valuation set by the Land Registry, it's advisable to review each case carefully. You can find more information on this topic on Resitax's real estate law page in Mallorca: Real Estate Law in Mallorca
