What kind of information contains the document?

It is important to know how to read the urban property booklet, so you can make a correct management of the Property Tax Value (VPT) of the properties and the amount payable of Municipal Property Tax (IMI). Anyone can read it.

Two very important aspects: the Fraction Areas and the Age of the Property.

The Fraction Areas:



According to the Municipal Property Tax Code:


Private gross area (Aa)

Corresponds to the total surface, measured by the outer perimeter and axes of the walls or other separating elements of the building or fraction. Includes closed private balconies, cellars and private attics with identical use to the building or fraction (CIMI), bedrooms, kitchen, living room , hall, corridors, bathrooms. Excludes open balconies, terraces and any common areas.


Dependent gross area (Ab)

These are covered and closed areas for exclusive use, even though they constitute common parts, located outside the building or fraction, whose uses are accessory in relation to the use for which the building or fraction is intended. It is considered for that purpose, accessory locations: garages, parking, storerooms, animal facilities, attics or cellars accessible and balconies, as long as they are not integrated in the private gross area, and other private places with a function different from the previous ones.


Property Age:

The urban building book should be compared with the certificate from the land registry office. This is because in some cases the urban building book does not mention the real age of the fractions, being necessary its verification through the certificate of the land registry office.


How to change the data of Caderneta Predial?

When you want to sell your property, the value of the square meter is crucial. Because depending on this, the potential buyer will assess whether or not it is a good deal. In this case, the square meter is a unit of measurement of the areas present in the Caderneta Predial. These are: total land area, building planning area, gross construction area, dependent gross area and private gross area. All must be correct.

If there is an error, you must request its correction from the Tax Office. In turn, if the information present in the Land Registry of the Conservatory is not in accordance with those of the Land Register, you must change it in the Land Registry with the updated Land Register.


It is also important that the Current Asset Value (CIMI) is updated, as it is used in the calculation of IMI, in addition to IMI and IMT. In case you need to make your correction, you must complete the IMI Model 1, or go to the finance department or via the finance portal. However, before deciding on the correction of the CIMI, you should use the VPT finance simulator, as it may be beneficial or not in relation to the amount of taxes to be paid. Because in the revaluation of the equity value by Finance, the value of the VPT may decrease or increase.


If there are other changes as in the case of transfer of property, sale, inheritance, donation or others, you will have to go personally to the Land Registry Office to change the ownership of the property.
