The implementation of income taxation of the rental value of owner-occ
upied apartments is a political problem in Denmark because of the comp
etition among parties to get hold of the marginal voters living in own
er-occupied houses. The transition from a direct income tax to a direc
t expenditure tax involves some opportunities to implement a correct t
ax of owner-occupied houses and apartments without hampering the exist
ing owners. This is a consequence of the need to compensate the tax pa
yers for the income tax already paid on savings and investments in the
ir houses and apartments.
