Art. 23 Tax Act (StG)
Art. 23 StG
1. **Subject to Taxation are the Income from Immovable Property, Particularly:**
a. all income from leasing, renting, usufruct, or other use;
b. the rental value of properties or parts of properties made available to the taxpayer for their own use based on ownership or a gratuitous right of use;
c. income from building right contracts;
d. income from the exploitation of water rights, gravel, sand, and other components of the soil.
2. The rental value referred to in paragraph 1 letter b is also subject to taxation if the property is rented or leased to a related person at a rent significantly deviating from the market value.
3. The governing council enacts the necessary implementing provisions for the uniform assessment of the imputed rental values of self-occupied non-agricultural properties or parts of properties. A schematic, formula-based evaluation of the imputed rental values may be provided. However, the following guidelines must be observed
a. the imputed rental value is to be set below 70 percent of the market value, considering the promotion of home ownership and private provision;
b. quality characteristics of the properties or parts thereof, which would significantly influence rent in the event of renting, must be adequately taken into account within the framework of a schematic, formula-based evaluation of the imputed rental values;
c. for properties or parts thereof that are self-occupied at the residence, the imputed rental value must also be determined considering the actual use.
4. For hardship cases, the governing council can provide a reduction in the imputed rental value of the primary residence.
