In 1997, the Irish government introduced reforms to revolutionize corporate taxation, with focus on creating opportunities for tax neutrality and on reducing the standard corporate tax rate. This paper studies the relationship between this Irish corporate tax reform and income shares at the top and the upper middle of the distribution. Using the synthetic control method, findings suggest that the reforms had large positive effects on the income share of the top 1% and sizeable negative effects on the upper middle 40% of income earners. Such heterogenous effects indicate increasing income inequality due to targeted corporate tax incentives.
