tax system

One of the most important economic topics in every country is considering tax issues as a way of increasing the government's income through attracting public confidence by observing the principles of proceeding in the tax system of the country which might likely cause a national production boom, increase economic growth rate, reduce unemployment and the fair distribution of wealth. In this regard, since the majority of taxpayers in a country pay taxes and at the same time their rights might be threatened, it is therefore necessary to establish courts and tribunals for settlement of rights and resolving hostility, and because of the close connection of individuals with the issue of tax, they may refer to these authorities more than others. Accordingly, references must be made in accordance with a fair proceeding in order to best determine the rights of the modalities, which will not be achieved except through the adoption of fair trial principles that are endorsed and supported by international legal institutions and are accepted as the principles for the implementation of fair results in the global prosecution system. Today, there are several systems of tax proceedings in different countries, each of which has weaknesses and strengths in terms of affinity and fairness of fair proceeding principles. In this paper, by examining the tax jurisdiction of Iran, the United States, Britain, Germany and France, as well as the patterns of exploitation of each of these systems and comparing the tax systems of these countries with the accepted principles of fair proceeding, the degree of proximity or the distortion of the above tax systems into the principle of the implementation of justice, which should be the ultimate goal for lawmakers, will be studied.

The article presents the results of studies on the development of new statistical and econometric approaches to modeling budget policy. The obtained results are applied on the example of tax revenue modeling. Accounting for various factors, including through the use of mathematical methods, will allow you to plan reforms with a scientific position. In particular, this is especially true in connection with the introduction of multi-year budget planning. To identify the main threats to the tax base, the phenomenon of “tax passes” wasused, which is based on an assessment of the effectiveness of a tax credit. The main participants in the formation of the “gross gap” in the value added tax revenues in Ukraine are shown. A correlation and regression analysis of the natural logarithms of the gross domestic product and tax revenues is carried out. This allowed us to determine the elasticity of tax revenues and GDP in Ukraine. A change in GDP directly affects the amount of tax payments to the budget, and the rate of change of indicators is proportional and changes insignificantly. These results allow us to strategically model the reform of discretionary tax policy mechanisms based on a quantitative assessment of tax gaps and the elasticity of tax payments. The authors were able to substantiate some proposals for reforming the budget policy regarding tax revenues.
