The market economy is characterized by the fact that primary income distribution is unequal, so it tries to make a "more just" re-distribution of income. The main aim of this article is to show what instruments are used by the State to reduce income differences in society and to assess whether these instruments are efficient in achieving this goal. Gini coefficient is a measure used to assess efficiency. In this paper attention will be focused primarily on the States income policy whose task is to ensure a more fair distribution of income in society.
