A foreigner who is a non-resident of Spain has the right to sell his property to another non-resident foreigner entirely in foreign currency, with payment made outside of Spain. It should be noted that, since 1997, a 5% tax retention is effected by the tax authorities upon the sale of any property owned by a non-resident vendor, which is applied towards the capital gains tax (currently 35%).

The profit on the sale is reduced by a small percentage for each year of ownership in compensation for inflation. If the amount withheld is greater than the tax due, it can be reclaimed in part from the tax office. Those sellers today who have owned their property prior to 1986 currently pay no capital gains tax on a sale.
