Due date: January 15 of each year.
The so called ´Solidarity Tax´ for the Strengthening of Housing Programmes (Impuesto Solidario para el Fortalecimiento de Programas de Vivienda), Law # 8683, commonly referred to as the 'Luxury Home Tax' only applies to houses, condos and apartments of which construction/building value exceeds a certain amount. Said amount and the methodology to calculate it is established by the Tax Office (₡133.000.000,00 colones in 2020, ~US$ 240K, this amount is adjusted each year). The amount to be used for 2021 will be available on or before January 05, 2021.
The entity or person obliged to file and pay it, is that one that owns the ¨Luxury Home¨ as of January 1st. The value of the main construction and additional or associated facilities (e.g. palapas, swimming pools, perimeter walls, internal streets, sports courts, etc.) must be determined. The Manual of Unitary Base Values for Constructive Typology and a tool are available for contributors to determine the value to be declared for the luxury tax. You can check the link provided by the Tax Office related to this matter: http://www.hacienda.go.cr/contenido/13173-impuesto-solidario
Once the value of the constructions is determined, if it exceeds the exempt amount established by the Tax Office for the particular year being analyzed, you must then calculate the value of the associated land as per the valuation parameters and then add it. The sum of these values will provide you with the total value of the property to be declared.
Those liable for this tax shall fill out the form called 'Formulario Único de Inscripción, Declaración y Pago Impuesto Solidario para el Fortalecimiento de Programas de Vivienda, Law # 8683' every 3 years, and, pay the tax annually. The next assessment shall be made on 2022.
