Cadastral income

Cadastral income (CI) is used as the basis for collecting property tax and determining the property income taxed in personal income tax.

CI is not an actual income, but a notional income corresponding to the average normal net income that the property provices its owner in a year. It is therefore the net average rental value in a year for the property at the reference data. This reference data has hitherto been 1 January 1975.
