Corporate Income Taxation Dynamics: A Comparative Analysis of Portugal, Germany, Belgium, The Netherlands, and Luxembourg

This study seeks to undertake a comprehensive analysis and comparison of the corporate income tax systems across select European Union nations, with a specific focus on discerning disparities between the individual income tax (IIT) and corporate income tax (CIT) frameworks prevalent in Portugal, Holland, Belgium, Luxembourg, and Germany. With an institutional theory lens, we applied document analysis to describe the distinctive attributes characterizing each tax regime within the purview of competitive dynamics and fiscal competitiveness. Despite inherent limitations stemming from challenges in accessing tax-related information and potential oversights regarding socio-political determinants, this study underscores the imperative of grasping the intricate interplay between tax imposition levels and broader economic development trajectories. By furnishing valuable insights into prospective reforms pertaining to Portugal’s corporate income tax architecture, this scholarly inquiry significantly enriches our comprehension of tax competitiveness within the overarching framework of the global economic environment.
