How to calculate the tax value of your own home (primary dwelling)
The Norwegian Tax Administration calculates a property value (calculated market valu for a residential property) based on Statistics Norway's statistical information concerning house sales. The calculation takes into account the property’s location, floor area, year of construction and type of dwelling.
The property’s housing value is equal to the floor area of the property multiplied by a price per square metre based on statistics of property sales.
The calculation is based on information concerning the property's area, location, age and type.
The tax value is a given percentage of this property value. The tax value of primary dwellings is set at 25 percent of the property value (90 percent for secondary dwellings).
Usually, information on property area, year of construction and type of housing is stated on the tax return.
You must still check that the pre-completed information on your property in the tax return is correct. Should any of the information be incorrect or incomplete, you must correct it in the tax return.
If you want a certificate on already reported values, you can log in and order a certificate of the tax value of your property. The certificate states the total tax value for the entire property.
