How the taxable value of buildings is determined

The taxable value of buildings is based on the following:

The location of the building has no effect on its taxable value. The calculation basis is the same everywhere in Finland. The amount of real estate tax is based on the tax rate that the municipality has determined for buildings.

Area

For the purposes of real estate tax, the area of a building is determined by its external dimensions.

If a building’s area stated in your real estate information seems larger than you think, note that this may simply be because of the different measurement techniques.

See the detailed guidance for more information about area (in Finnish and Swedish, link to Finnish).

Age depreciation 

The age of the building affects its taxable value. As the building ages, its value decreases according to the annual rates of age depreciation.

The rate of depreciation is determined by the building type and the bearing structure.

See the detailed guidance for more information about age depreciation (in Finnish and Swedish, link to Finnish).

Building type 

The building type is defined when the building permit is issued. The type is determined by the building’s characteristics, not just by its purpose of use.

See the detailed guidance for more information about building types (in Finnish and Swedish, link to Finnish).
