The biggest beneficiaries of tax concessions on owner-occupied residences are the wealthiest in the community, according to this report.

The report finds that the tax system provides indirect assistance to owner-occupiers worth about $45 billion annually. Most of this ($30 billion) is due to the exemption of owner-occupied homes from capital gains tax. Individual property investors benefit from $5.4 billion in tax concessions each year, mainly due to the 50% tax discount on capital gains and to negative gearing.
