Abstract: There is still quite a large amount of non-monetary income which is not covered in PIT tax base in China. Therefore, in terms of the families with the same real income but different income structure, those who earn more monetary income but less non-monetary have to pay higher taxes, while those with less monetary income but more non-monetary pay less. That will cause the family income inversely regulated. This paper is focusing on an empirical study on the distribution effects of PIT in China by using the Panel Threshold Model. The results show that if the ratio of those fiscal dependents, who can obtain more non-monetary income, is less than 16%, the income distribution would not be seriously affected by PIT. However, if the ratio is larger than 16%, the income gap would be significantly exacerbated by PIT with the contrasted feature of “taking the poor for the rich”. Therefore, it is proposed that the non-monetary income be put into PIT tax base as early as possible. Moreover, the major function of PIT should be set to regulate the income distribution by raising revenue from higher-income groups.
