要旨:
This article compares national income tax reforms during
the last 25 years. There were two competing models of income tax reform, ‘comprehensive’ and ‘dual’ income taxation, the latter of which was in many ways more successful. The reason lies in the structural constraints policy makers face. While taxation of capital income is very costly, creating incentives to lower marginal tax rates, the high overall tax burden on labour makes it difficult to reduce tax rates on labour incomes. These conflicting pressures point towards separate tax rate
schedules for capital and labour, as is characteristic of dual income taxes. The analysis has implications for the role of income taxation in achieving social policy outcomes. Most importantly, while progressive taxation of capital income is constrained by high costs, policy makers
willing to separate capital and labour income taxation can use the income tax to reduce the tax burden on low wages.
