How is Plusvalía Tax calculated?

It is based on the official value of the land, which is always lower than the actual market value. The tax is charged at between 10% and 40% of the annual increase in the value of the land. The exact percentage depends on a number of factors including the location of the property and the length of time between sales. Local authorities periodically carry out valuations of land and maintain up-to-date records in order to calculate Plus Valía charges.
