Castile and León Court Overturns Cadastral Reference Value: What Does This Ruling Mean for Taxpayers?
What is the cadastral reference value?
Since January 1, 2022, with the entry into force of Law 11/2021 on measures to prevent and combat tax fraud, a new concept was introduced: the cadastral reference value.
This value, calculated annually by the tax administration, is used as the taxable base for the Property Transfer Tax and Stamp Duty (ITPAJD) and the Inheritance and Gift Tax.
How does it work?
Before submitting the tax form (usually Form 600), the tax adviser must check whether the cadastral reference value exceeds the actual sale price. If it does, the reference value is used as the basis for calculating taxes.
What’s the problem with this system?
The cadastral reference value is determined without considering the actual condition of the property, based solely on prices from registered sales at notaries and reported to the Cadastre.
There is no physical inspection, nor is the property owner consulted.
This has led to unfair situations, such as the one reflected in a recent ruling from the High Court of Justice of Castile and León.
The case: an inflated value and a disproportionate tax
A taxpayer sold a property for €300,000, but the assigned cadastral reference value was €408,327.19.
As a result, the seller had to pay €10,832.72 in ITPAJD, calculated on a value much higher than the actual sale price.
Even though the seller submitted an independent appraisal proving the poor condition of the property, the tax administration rejected the claim.
The State Attorney argued: “As long as there is a reference value, no other valuation methods apply.” In other words, the reference value was treated as absolute and unquestionable.
What did the Court decide?
The Court ruled in favor of the taxpayer.
The key was that the property was in a ruinous condition, proven by an appraisal and the testimony of a real estate agent.
The expert stated that while the exterior appeared acceptable, the interior had been vandalized was uninhabitable.
The judgment concluded that the administration should have applied the corrective coefficient for properties in ruinous condition (Coefficient I), as established by the Resolution of November 10, 2021, from the General Directorate of the Cadastre.
What conclusions can we draw?
- The tax administration acts as both judge and party, setting a value without visiting the property or allowing real defense for the taxpayer.
- It is possible to challenge the reference value, but many affected people don’t do it because the legal process is costly and often not worth it for small differences.
- This ruling sets a valuable legal precedent, and legal professionals should urge lawmakers to revise a system that fails to reflect market reality.
What should you do if you’re in a similar situation?
- Consult a lawyer: They can assess whether there is a legal basis to appeal.
- Gather evidence of the property’s actual condition: photos, expert reports, and professional statements.
- Don’t give up on claiming: Even if it seems difficult, rulings like this demonstrate that it’s possible to win.
