Although a complex taxation system can affect a company's operations, its negative effects can be significantly greater at the macroeconomic level. Given the fact that it can make it more difficult to attract investments and collect revenue, the corporate income tax system has been the subject matter of numerous research studies for many years now. Modern business conditions initiated their frequent reforms, as well as the numerous dilemmas related to them. The paper deals with the taxpayer as an element of corporate income tax. Although numerous papers investigate the (dis)unity of tax systems in defining corporate income taxpayers, few authors examine the economic effects of these discrepancies. Also, most research studies are focused on examining the other elements of this tax form, such as the tax rate or tax incentives. In this paper, an effort is made to find a connection between the form of the organization of a business entity and the tax burden in the domain of corporate income tax. The research study aims to indicate the importance of the economic effects of this tax element and to propose its reform. The research has confirmed the initial assumption, respectively; it has shown that different forms of the organization of business entities bear different burdens of paying corporate income tax, which affects the amount of the tax revenue that could be collected. The results have shown that the sampled companies paid less tax due to corrections and adjustments in tax balances and tax returns.

The problem of pension financing in the system of mandatory pension insurance in the Republic of Serbia became actual after the great economic crisis of the 1990s, although this problem had been present before. Accordingly, considerable attention has been paid to the analysis of determinants of pension expenditures. Considering the fact that in the Republic of Serbia the possibilities for reducing expenditures in the system of mandatory state pension and disability insurance have already been exhausted by reforms so far, it is necessary to consider other measures and possibilities for changing the design of the pension disability system. Therefore, the subject of this paper is the analysis of the relationship between pension beneficiaries, the type and amount of pensions. The aim of the paper is to analyze the influence of the pension beneficiary and the type of pension on the amount of the pension, based on the analysis of the collected data.

The aim of this paper is to examine the impact of tax incentives as determinants of economic development on revenues from corporate income tax in Serbia. The study uses data from secondary resources of the Ministry of Finance for the period 2007–2018 by employing regression and factor analysis. The research includes 10 tax incentives that were used in Serbia in the analyzed period. The methodology of empirical verification involves the implementation of correlation analysis, regression analysis and factor analysis. We opted for the application of Principal Component Analysis (PCA) because this method extracts the important data in order to present a set of new variables called main components. The model obtained in this way formed the determined components of tax incentives as independent variables. The model considers tax incentives grouped into four components. The results of empirical research indicate that there is a positive impact of certain tax incentives on revenues from corporate income tax and proved the paradox of tax collection initiated by tax incentives. The model proved that tax incentives explaining the first component had a positive effect on revenues from corporate income tax. Namely, the incentives for investments, incentives exempting the taxpayer from paying corporate income tax for work training, professional rehabilitation and employment of disabled persons, as well as a reduction based on the elimination of double taxation have a positive effect on revenues from corporate income tax. The positive impact of tax incentives can be explained by their effectiveness. The results show that tax incentives policy must be defined in detail for the purpose of achieving the economic and social goals.

Abstract. The essential research intention in this paper

In modern tax systems, there are different forms of consumption taxation, and the most common among them is value added tax. VAT is one of the most important categories of tax revenues, considering the fact that it is characterized by a high degree of plentifulness. However, the main disadvantage of VAT is the fact that it distributes the tax burden regressively in relation to the taxpayer`s income. Given that the relative share of consumption in income falls as income grows, VAT, determined at a unique rate, hits harder the poorer than the richer part of the society. The aim of this work is to show the dominant relationship of the principle of plentifulness in relation to fairness in value added taxation the point our the existence of regression problems and possible measures that can be applied to meet the principle of fairness in taxation.
