Non-resident property owners in Costa del Sol often face common tax miscalculations that can lead to unexpected costs, particularly concerning imputed income tax (Impuesto sobre la Renta de No Residentes - IRNR) and wealth tax (Impuesto sobre el Patrimonio). A frequent oversight is underestimating the taxable base for IRNR, which applies even if the property is not rented out. This tax is calculated on a percentage of the cadastral value and must be paid annually. For 2026, it's crucial to understand any adjustments to these percentages or cadastral values. Another area of miscalculation arises with wealth tax, which applies to non-residents whose net assets in Spain exceed a certain threshold. While there is a national exemption, regional variations in Andalucia can significantly impact the final amount owed. Many non-residents fail to account for the annual declaration and payment of this tax, assuming it only applies to high-value properties or residents. Furthermore, when selling a property, non-residents are subject to a 3% retention on the sale price, which is then offset against their capital gains tax liability. Misunderstanding how this retention works, or incorrectly calculating the capital gains tax (which can vary based on acquisition costs, improvements, and inflation coefficients), can lead to either an unexpected payment or a complex refund process. Non-residents also sometimes overlook the municipal capital gains tax (Plusvalía Municipal), which is levied by the local council on the increase in value of the land upon sale. Its calculation can be complex and depends on the cadastral value of the land and the number of years of ownership, often leading to underestimated costs. Finally, errors in reporting rental income, particularly failing to deduct eligible expenses according to Spanish tax law, can result in higher IRNR on rental earnings. It is advisable to engage a qualified tax advisor specializing in non-resident taxation in Spain to ensure accurate compliance and avoid these common miscalculations.
