How the amount due for the IBI bill is calculated

The annual amount to be paid for the IBI is calculated by applying the Tax Rate to the payable amount "Base Liquidable" and deducting the benefites where applicable.

To obtain the payable amount, you apply the legally established reduction to the rateable base (cadastral value) in the municipal districts where cadastral values have been updated or renewed.

The main purpose of the payable amount is to avoid a sudden increase in the amounts due for rates as a result of a rise in the cadastral value.

Example of calculations of the IBI:

Cadastral Value: 62.644,91 Euros
Payable base: 34.428,10 Euros
Tax Rate: 0,80%
Yearly amount due: 34.428,10 X 0,80% = 275,42 Euros

In the municipal districts where the cadastral values have not been renewed, the payable amount is the same as the cadastral value.

Why has the bill gone up this year?
Every year there is a percentage increase in the cadastral value, approximately in line with the CPI. The percentage is laid down in December of each year.

If the cadastral value is renewed in the municipal district, the payable amount is also increased on a yearly basis during a 9-year period after the new values have come into effect.

Town Halls can also modify the tax rate applied to determine the amount due.
