How to calculate surplus value in Barcelona

Surplus value is a mandatory tax.

Selling a home is a process that carries with it certain costs. Therefore, when selling a property, we must consider a whole series of factors. One of the payments to consider is the so-called municipal surplus value. Today, in the BARNES blog, we tell you how this tax is calculated in Barcelona.


The municipal surplus value is one of the taxes with which Spanish people are most familiar. It is known as the Tax on the Increase in Value of Urban Land. This is a tax levied on the increase in value of land of an urban nature at the time it is transferred. 

When carrying out a transaction of sale of a property, the surplus value appears as one of the main taxes to be paid, being the Tax Agency the administration in charge of its collection. This is a mandatory tax levied on the gain on the value of the property once it is processed, sold, inherited or received after a donation.  

It should be noted that the tax arises with the transmission of the land, whether there is a building on them. Therefore, when it comes to the transmission of a dwelling, what is taxed is the transmission of the land on which it is built and not the building itself.


This payment can be calculated through two basic methods: the actual method or the target system. 

To calculate the surplus value through the real method we must know, first of all, the surplus value that has been obtained after the sale of the property, subtracting the price of the transaction and the price for which it was acquired. To obtain the tax base we must multiply the surplus value obtained in the previous step by the percentage that refers to the cadastral value of the land on the value of the property. Finally, we multiply this result by the tax rate that, in the case of Barcelona City Council, is defined at 30%. 

If we follow the objective method, we will start by calculating the tax base. The surplus value will be obtained by calculating the multiplication coefficient of the lower table by the cadastral value of the land. The result obtained must be applied to the tax rate set by the city council, 30%. 


This tax can be paid in three different ways. Through the website of the Barcelona City Council, accessing its portal and downloading the municipal surplus value processing form. It must be filled in and sent via the Internet or by printing the self-assessment paper and presenting the payment through a collaborating bank. It can also be accessed by telephone, by calling toll-free 931 537 010 or by requesting an appointment at the OACS or the IMH
