Investment and business use land comprises a broad range of land uses and classifications that attract exemptions and concessions from state land tax, which do not necessarily apply to local government rating. These concessions and allowances add to the tax revenue expended on the principal place of residence and further impact the reform of this tax across Australia. This chapter examines the concessions and exemptions, including the investment threshold, the exemption for primary production land and a brief highlight on the exemption of charitable organisations. After accounting for the principal place of residence exemption, investment threshold, the exemption of primary production land and land held by not-for-profits, less than 20 per cent of land in Australia is subject to state land tax. This is in contrast to over 98 per cent of all rateable land which attracts local government council rates.
