Selling Inherited Property in Spain: Hacienda Confirms IBI Does Not Reduce Capital Gains Tax

Selling an inherited property in Spain is a process that, beyond the commercial decision, demands meticulous tax planning. One of the most common questions among heirs deciding to sell an inherited property is whether the Impuesto sobre Bienes Inmuebles (IBI), or Spanish Property Tax, can be used to reduce capital gains and, consequently, the overall tax bill. Spain’s General Directorate of Taxes (DGT) has issued a binding consultation (V0604-26) definitively settling this matter: IBI is not deductible.

According to Spanish regulations, the capital gain or loss from selling a property is calculated as the difference between its acquisition value and its transmission value, as stipulated in Articles 33 and 34 of Law 35/2006 on Personal Income Tax (IRPF). Specifically for inherited homes, the acquisition value is determined by the rules of the Inheritance and Gift Tax (Article 36), including inherent expenses and taxes related to the acquisition borne by the heir. However, the DGT has explicitly stated that IBI is not considered an inherent expense for either the acquisition or the transmission of the property. Therefore, it cannot be factored in to adjust either the acquisition or transmission value when calculating capital gains.

This clarification is crucial for property owners and prospective sellers. Nevertheless, the IRPF Law does permit the inclusion of other costs to optimize the tax calculation. To increase the acquisition value, heirs can add the proportional part of the Inheritance and Gift Tax corresponding to the property, the Municipal Capital Gains Tax (Plusvalía Municipal) if paid by the heir, and expenses such as notary fees, Property Registry fees, or advisory costs related to the acceptance and formalization of the inheritance. Conversely, the transmission value can be reduced by expenses directly linked to the sale, including real estate agency fees, notary and registry costs for the transaction, mortgage cancellation fees, habitability or energy efficiency certificates, and community fee clearance, as well as the Municipal Capital Gains Tax if payable by the seller. It is essential that all these expenses are duly documented for their deduction with Hacienda.
