The tax office says my home is worth more than I declared
The valuation must be reasoned, and you can request an independent expert valuation (tasación pericial contradictoria) within the appeal period.
What they must give you
A reasoned valuation proposal, with the methods and criteria used.
«comunicará la propuesta de valoración debidamente motivada, con expresión de los medios y criterios empleados.»
How to defend yourself
The valuation is not appealed on its own: you request the independent expert valuation or challenge it when appealing the assessment.
«Los obligados tributarios no podrán interponer recurso o reclamación independiente contra la valoración, pero podrán promover la tasación pericial contradictoria»
By when
Within the period for the first appeal or claim against the assessment.
«dentro del plazo del primer recurso o reclamación que proceda contra la liquidación efectuada de acuerdo con los valores comprobados administrativamente»
