Since the endogenous growth model appeared in the economic theory, taxation has been considered as one of the key determinants of the economic growth. In the public finance theory, taxation is considered to have a negative impact on economic growth, which is explained by implications of tax revenues distortions on the economic activity. This assumption has been investigated by many empirical studies. The aim of this paper is to analyse the impact of personal income taxation on economic conditions in Croatia in the long-run. After providing a brief insight into the economic and the public finance theory regarding taxation and economic growth, previous relevant research is presented. The empirical analysis of the impact of personal income taxation on economic conditions in Croatia is conducted using the Johansen cointegration approach. The existence of cointegration is examined and the error correction model is estimated using monthly data from January 2000 to March 2016. The results of the research show that personal income taxation in Croatia has a significant negative impact on the economic growth in the long-run, which is in line with the economic theory and relevant empirical research.

Personal income taxation remains an ongoing issue in Croatia. It is used as an important instrument of income redistribution. Moreover, it directly affects purchasing power of the working population. Numerous changes have been made in this type of taxation since the establishment of Croatian tax system. The aim of this paper is to analyse possible determinants of personal income taxation in Croatia. After offering brief insight into public finance theory regarding personal income taxation, the structure of personal income taxation in Croatia is explained. The empirical analysis of the determinants of personal income taxation in Croatia is conducted using cointegration analysis. Economic conditions, average monthly wage, and number of taxpayers are used as determinants of personal income tax used in this research. The cointegration analysis is conducted using monthly data from January 2008 to February 2016. The results of the research show a statistically significant negative impact of economic conditions and statistically significant positive impact of average monthly wage and number of taxpayers on personal income taxation in long run, what is in line with economic and public finance theory.
