Specifically, Song Xiaowu first proposed to further improve the personal income tax system. Expand the scope of comprehensive collection, implement the family declaration system, appropriately reduce the highest marginal tax rate of labor income, and increase the adjustment of short-term capital gains and property transaction income. "Personal income tax with progressive tax rate system has a strong positive adjustment effect on residents' income distribution. However, China's personal income tax has been raised many times, although it has reduced the tax burden of the working class and played a certain role in promoting consumption. At the same time, it should be noted that this move has caused the current personal income tax coverage to be too narrow, the income scale to be too small, and the proportion to be too low, which has seriously restricted the positive adjustment of its income distribution. " Song Xiaowu said that it is not appropriate to raise the personal income tax threshold during the 14 th Five-Year Plan period.

Second, steadily levy real estate tax. Song Xiaowu pointed out that at present, housing prices are too high, and residents' mortgages are growing rapidly, which has largely squeezed residents' consumption expenditure. The proportion of urban residents' housing expenditure in disposable income increased from 7.3% in 2003 to 26.7% in 20 19. "In order to curb the investment behavior of commercial housing, on the basis of summing up the experience of exploring real estate tax in some cities, we should use Internet big data technology during the" 14 th Five-Year Plan "period to find out the actual situation of residents' housing as soon as possible and start to levy real estate tax steadily. The main target of real estate tax collection is not the majority of low-and middle-income ordinary workers, but high-income multi-family housing, which can design a higher progressive adjustment mechanism. " Song Xiaotong said.

Third, Song Xiaowu suggested studying inheritance tax and gift tax during the Tenth Five-Year Plan period. Inheritance tax is a common means to adjust the gap between the rich and the poor all over the world. In 1996, the ninth five-year plan for national economic and social development and the outline of 20 10 long-term goals approved by the Fourth Session of the Eighth National People's Congress, China clearly proposed to gradually levy inheritance tax and gift tax. But so far, the inheritance tax has not been introduced, and it is very controversial. "A large number of families with huge assets have emerged in China, and they have the conditions to levy inheritance tax and gift tax. Those who oppose the collection of inheritance tax are untenable in the face of realizing the social concept of * * *. " Song Xiaotong said.
