The issue of public revenues, i.e. social revenues have a mutual relationship with the existence of public and social bodies and their functions. The Republic of Kosovo as the youngest state to the world is to the phase of constitution and consolidation of its development. As such it has a number of challenges and problems. One of them is the consolidation and creation of stable macroeconomic policies, including monetary policy. Exactly this will be the topic of research and issues that will deal with during this paper. It is impossible for it to function as a state without a sound revenue system. Kosovo mainly receives revenues from certain sources, and among them, the most important source is taxes. Taxes, among others, not only to the Republic of Kosovo, but also beyond. The structure of this paper is divided into several main parts. As a start, an attempt will be made to give a perspective on taxes as the main sources of public revenue and its impact on different economic systems to different countries. Then an overview will be given on the composition and content of the tax system of the Republic of Kosovo and its comparison with the tax systems of the surrounding countries. In the study, a variety of methods were adopted, such as descriptive method, comparative method, interviews and surveys, and analysis of various acts and statements. The obtained data were analyzed using the statistical tests, such as regressions and hypothesis testing. Results have revealed that Kosovo's budget is like most budgets to the world, which bases its revenues on taxes to a very large extent, respectively with an absolute percentage. Depending on the tax policies set by the Republic of Kosovo, the budget structure of taxes can be seen to terms of the share of taxes to the total value of Gross Domestic Product.
