Effective Tax Rates in Corporate Taxation: a Quantile Regression for the EU

Francisco J. Delgado, Elena Fernandez-Rodriguez, Antonio Martinez-Arias


In this work we study the determinants of the effective tax rates for corporate taxation in countries of the European Union. First, we carry out an exhaustive review of the empirical literature where no consensus is reached about the signs of the determinants and we can observe that in the case of the European countries this topic has scarcely received attention, contrary to the US case. Then from the Compustat database and for the period 1992–2009, we estimate quantile regressions that allow possible nonlinear relationships to be detected. The estimations reveal different effects of factors such as size, debt, asset composition and profitability on the effective corporate tax rate depending on the decile. In short, for companies with lower ETRs, the most influential variables are the size, the intensity of inventories and the profitability, whereas for the companies that suffer the highest fiscal pressure it is debt that turns out to be the strongest determinant. These results justify the employment of quantile regression instead of the traditional linear approximations.
