On January 18, 2013, the National Bureau of Statistics released China’s Gini coefficient from 2003 to 2012. The data show that over the years, the Gini coefficient of China has crossed the warning line 0.4. The government should exercise vigilance on this issue and adopt effective regulatory measures to promote income equality. Personal income tax is the most important means of promoting income equality. This paper calculates the adjustment direction and intensity of personal income tax of urban residents in Jiangsu Province from 2002 to 2011, and provides policy suggestions to narrow the income gap.
