The European Council has issued a draft of Directive for a common consolidated tax base of corporate income tax in 2011 and updated in 2012. This draft must be approved by all member states, but some of them, however, have expressed on the draft in negative way. Because of the severity of this problems, the authors decided to focus on this topic within this article, which deals with the calculation of the tax base by the laws of the Slovak Republic and by Common Consolidated Corporate Tax Base (CCCTB); and evaluate whether the tax harmonization of direct taxes would be advantageous for the particular business.

The scientific contribution focuses on the statistical analysis of selected indicators of the financial performance of enterprises, which within the same accounting period are reported according to national accounting legislation and according to IAS/IFRS. Due to the different approach to the reporting of asset and liability items, individual items of the statements change, which is the reason for achieving different values of financial liquidity indicators, or the golden balance rule and other financial indicators. In the introduction to the article, we will present similar research in this area. In this paper we will deal with statistical testing of absolute changes of indicators using the Wilcoxon test and t-test. The main hypothesis of the paper is to examine whether there are statistically significant differences between the values of the indicator according to national accounting legislation and IAS/IFRS.

Education is an important tool for improving many aspects of life, including socio-economic status or well-being.Limitations: Participants of the electronic questionnaire participated in the answers according to the activities and projects prepared by a particular elementary school.Conclusion: Higher life expectancy, pension reforms, the availability of a more comprehensive range of financial products and services mean that the ability to make well-informed financial decisions is increasingly considered an important life skill. If a school fails at certain points during a child’s study, it is assumed that this will have a negative long-term impact on the child’s life in the future, as ending a school without sufficient qualifications can lead to difficulties in ensuring equal participation in the financial, civil and social aspects of modern society.
