Nowadays, influence of international business groups on the individual countries’ economic systems is still growing. Effective tax rate showing a real level of the tax burden is one of the most important parameters of each economy. This article analyses the factors affecting the effective corporate income tax rate of the “blue chips” in the Czech Republic and in the Russian Federation. The factors are divided into two groups: external and internal ones. The hypothesis states that the internal factors (assets, debt ratio and equity) are more correlated with the dependent variable than the external ones (Paying Taxes index and average oil price). The regression analysis, particularly, panel data model with fixed effects, was used to estimate influence of the independent variables on the effective tax rate separately in Russia and Czech Republic. The research demonstrated that the mentioned internal factors are more significant for the Russian companies that the external factors. In the case of the Czech Republic, the same result was obtained with lower confidence level.
