Summary/Abstract: In this chapter, we estimate changes in income inequality in Poland from 2005 to 2017 that resulted from the changes in tax and benefit policy. We provide the theoretical background and describe the characteristics of the methods for such an estimation. Our results suggest that income inequality decreased (as measured with the Gini coefficient); however, the values of the measure varied in subperiods. We conclude that the changes in policy did not counteract the increase in income inequality during the economic slowdown, but they contributed to the decrease during the economic recovery.
