The complexity of tax systems is becoming increasingly important in the debate on international tax competition. Based on the underlying survey data of the Tax Complexity Index of Hoppe et al. (2019), this article provides a comprehensive comparison of the complexity of Germany’s and Austria’s tax systems while also taking the mean values of all countries covered by the index into account. In both Germany and Austria, the tax code is characterized by a relatively high degree of complexity. In contrast, the tax framework has a low level of complexity in both countries, with Austria being on average less complex than Germany.
