Corporate income tax gap estimation in the context of development of fiscal space

The article is devoted to the analysis of the corporate income tax gap as one of the indicators that characterizes the tax revenues that a country can accumulate accounting for its economic potential. The author summarizes the main theoretical views on the causes of the tax gap and investigates existing methodological approaches to assess the tax gap on corporate income tax in OECD countries. The article estimates the income tax gap under the OECD Revenue Administration - Gap Analysis Program, which is based on determining potential tax revenues by adjusting the aggregate indicators of the system of national accounts (gross output, mixed income), which, according to the analysis, averaged at 1.4% GDP in the period 2017-2019, which shows a potential for the development of the fiscal space of Ukraine. Upon analysis of the distribution of the tax gap between institutional sectors of the economy, the largest gap in income tax was found in the sector of foreign corporations whose potential tax revenues were estimated as tripled relative to the declared tax revenues accrued in the Consolidated Budget of Ukraine in 2018. The author conducted a comprehensive analysis of the effectiveness of corporate income tax in Ukraine on the basis of tax efforts and budget efficiency ratios, which revealed significant weaknesses in comparison with similar indicators in other countries. The main measures aimed at eliminating tax gaps in OECD countries are summed up and recommendations are made for Ukraine.

PERSONAL INCOME TAX GAPS: BIBLIOMETRIC AND ECONOMETRIC ANALYSIS

The article is devoted to the essence and features of the formation of personal income tax gaps. The object of the paper is 1795 publications indexed in the Scopus database on the tax gaps in the national economy. The time horizon of the study was in 1935—2021. On the basis of bibliometric analysis, the main directions of the study of tax gaps are determine, the trend of changing the number of publications on this issue is analyzed. It is concluded that the theory of tax gap management is quite young and is currently only in its infancy. By the VOSViewer tools, five patterns of frequency of use of keywords in scientific works devoted to the issues of forming tax gaps have been identified, their connection with other economic categories have been determined. The analysis of the publications indexed in the Scopus database on a geographical basis is carried out. Clustering international research networks based on bibliometric analysis of scientific papers on the theory of tax gaps management by geographical location have been done. The article identifies the top Scientific Journals indexed by the Scopus database in which the issues of tax gap management were published most often. According to the Scopus database the most popular theories within this problem are: social theories, inequality and tax morality, management and motivation theories, sustainable development theory, production theory, concepts of fiscal policy implementation. A methodical approach to the assessment of tax gaps for personal income tax is proposed. The personal income tax gaps for Ukraine and European Union countries has been estimated. An average volume of personal income tax gaps within 7—28 %, and there is no positive dynamics in its reducing. The countries with the highest volume of personal income tax gaps include Greece, Poland, the Slovak Republic, Turkey, with the lowest — Germany, Belgium, Latvia, Luxembourg. Based on the Multiple regressions test, the hypothesis about the significant impact of tax gaps on personal income tax on the country’s economic development indicators was tested. Graphical interpretation of the link between the personal income tax gap and GDP for Ukraine and European Union countries indicates a negative correlation between them.

Secondary Energy Sources and Their Optimization in the Context of the Tax Gap on Petrol and Diesel

This paper presents an energy management strategy for secondary energy sources and their optimization in the context of the tax gap on mineral oils represented by the tax gap on petrol and diesel. Energy companies face drastic economic and environmental challenges; therefore, this area necessarily requires the setting up of transparent economic instruments and, of course, production. The tax gap in VAT collection represents the gap between how much the state could potentially collect from VAT in accordance with the law and how much VAT really comes into the state coffers. The loss of tax revenues is caused by unpaid and undeclared tax liability. The Estimation of the Gap on Corporate Tax in Slovakia is a pilot project of the International Monetary Fund (IMF) in cooperation with the Institute for Financial Policy (IFP). The results present the estimation of the tax gap within a two-year delay. It is necessary to consider the estimation of the tax gap in the last two years as preliminary due to possible revisions of the national accounts data. Estimations of the tax gap from 2010 to 2017 indicate a decreasing trend. The significant part of the tax gap decrease can be observed from 2014. The main factor, which determines this decrease, is the improving condition of the Slovak economy. From the point of view of the tax gap, the volume of losses is decreasing and the volume of profit, from which the tax is paid, is increasing.

TAX GAP AS A CONSEQUENCE OF UNPAID TAX LI-ABILITIES

Tax evasion and grey economy are present in all countries. It’s es-timated that grey economy in developed EU countries is at around 10-15% of GDP, while it amounts to over 30% of GDP in Serbia. Therefore the subject of this paper is determining basic goals of Serbia’s tax policy, i.e. combating grey economy that complicates efficient resource allocation and slows down economic development, because economic subjects that are prone to tax evasion represent disloyal competi-tion to economic subjects that do business legally. In order to fight tax evasion, or-ganization and work of tax administration are of special importance.

ESTIMACIÓN DE LA BRECHA TRIBUTARIA PARA COLOMBIA: MEDIDAS PROACTIVAS PARA SU REDUCCIÓN

<p>Mediante el uso de un modelo de ecuaciones estructurales (SEM), en este artículo presentamos nueva evidencia de la sensibilidad de la brecha tributaria de Colombia a la evasión tributaria entre 1987 y 2018.

VAT Efficiency—A Discussion on the VAT System in the European Union

The effectiveness of the tax system can be analysed in various ways. According to the authors one of manifestations of such effectiveness is resistance to tax evasion. This phenomenon is influenced by multiple factors, with few being the level of VAT rates and the number of rates in force in the country concerned. The aim of the considerations is therefore to analyse how the standard VAT rate as well as the number of rates affect the effectiveness of this tax. The research was based on a literature query in the field of value added tax in the European Union. In addition, the problem of tax evasion was indicated and the aggregated data on the size of the tax gap in the Member States were presented. Then, there are the results of the research for 27 European Union countries for 2011–2019. The efficiency of VAT collection was modelled using square function, determining the significance of the parameters of this function, as well as the value of abscissa, which made it possible to group the countries based on how they maintained the efficiency of VAT collection over the analysed period of time. The final part of the study concentrates on the relationship between the efficiency of tax collection and the amount of both the basic rate and the number of rates. The conclusions of the research are as follows: a tax system with a small number of reduced rates, and preferably with one relatively low standard rate, is the system least susceptible to tax fraud. The research also shows a positive correlation between the value of the basic VAT rate along with the number of preferential rates and the scale of the tax gap, i.e., in countries with a higher standard VAT rate and a greater number of preferential rates, the tax gap is greater. The study will enable further investigation into the strategy of determining the optimal VAT rate and the process of its unification. Proposed changes may contribute to increasing the efficiency of VAT administration in EU countries, reducing the shadow economy, tax fraud and positively influencing economic growth.

VAT Gap Estimation and Influence of Selected Methods of Financial Administration on its Reduction

The aim of this contribution is to quantify the influence of selected methods on elimination of value added tax gap in the Czech Republic within the researched period 2015–2016. To find a possible share of influence of the VAT control statement on tax fraud following priority methods were set: VAT control statement invitation, initiatives from pairing check reports, tax checking and procedures for doubt removal. By quantifying these methods, the values of theoretical benefits are measured and further compared with value added tax gap within the researched period. To set the VAT gap estimation a method was used that calculates via cleaning gross domestic product based on the database of national accounts. By using this approach it was found out that with the influence of selected methods of financial administration there was a tax gap decrease in 2015 by 5.54% and for 2016 by 4.00%.
