A Quantitative Analysis on the Fair Effect of Individual Income Tax

A mature individual income tax system is the guarantee for its fair effect playing well.Through quantitative analysis,it can be found that the high-income groups benefit more than the low-income groups from each adjustment to the existing individual income tax exemption.Moreover,it is not quite rational that the excess progressive tax rate structure designs,combined with no special tax policy for high-income earners.All of which directly make it is difficult to play a fair role that adjusts the income gap and alleviates the contradiction between the poor and the rich for the individual income tax system.So,in order to make the individual income tax fairer,a series of tax system reform should be actualized as soon as possible,such as to put the indexation of tax exemption into practice,reduce the levels of tax rate,broaden the margin of low tax rate and try out consolidated income tax to the high-income earners.
