CORPORATE TAX RATES IN THE CONTEXT OF MACROECONOMIC DETERMINANTS AS CRUCIAL ASPECTS OF EFFECTIVE CORPORATE TAXATION IN THE VISEGRAD GROUP COUNTRIES.

The study examines the relationship between the effective tax rate, the nominal rate, and selected macroeconomic determinants. Correlation and regression analysis were used to analyze the impact of individual determinants and the nominal tax rate on the effective rate in the Visegrad Group countries from 2004 to 2022. The results of the analysis suggest different development directions of the standard tax rate in the Visegrad Group countries. While it decreased in the Czech Republic, the decline in Hungary and Slovakia was followed by an increase. In Poland, the standard tax rate remained almost unchanged. The results of linear regression demonstrated that in Slovakia, the Czech Republic, and Hungary the standard rate has a statistically significant impact on the effective tax rate. The result was not confirmed for Poland, where the standard rate was removed from the model due to the singularity problem. [ABSTRACT FROM AUTHOR]
