The Regional Tax Security Mechanism Based on Reduction of Tax Risks and Use of Information Technologies

. In today’s world taxes tend to be not only a tool for ensuring and maintaining economic and financial security, but also a source of possible threats and risks which may result in reduction of tax potential and budgetary imbalances between the central office and the provinces. In the conditions of economy digitalization, tax security as a prospective way of optimal modern tax management in the state and its regions includes elements of tax mechanism, information technology and technology of tax information protection. This article advocates the need for legislative recognition of the term "tax security", structures the components of tax security threats identification, which include elements of risk management and directions of tax administration improvement. Within the framework of the study of the tax security system, the functional relationship between tax risks and the structural elements of the tax mechanism, including its planning, regulatory, controlling and analytical components, was determined.


Introduction
In current conditions of social and economic development of the state and digitalization of the economy, the failures of ineffective tax policy, which may be caused by management mistakes and the influence of various negative external and internal factors, enhances the tax security threats.In the perspective it may negatively affect the development of the budget and financial systems of the state generally.

Problem Statement
The disproportions in the socio-economic development of regions are determined not only by the natural and climatic features and investment potential, but also by the ways of using the elements of tax mechanism, which is the basic regulator of the regional tax policy.In this regard, the issues of threat identification and ensuring national security through management, control and analytical elements of the tax mechanism, as well as the system of modern information technologies are becoming increasingly relevant and important.The lack of theoretical and practical development of the highlighted problem determines the need to identify threats and uncertainties in the tax environment from the perspective of ensuring the tax security of a region.
The following key research questions can be highlighted: an analysis of existing approaches to ensuring tax security of a region and identification of threat sources; studying the process of tax risk management; determination of the structure of a single center for generating the information database of tax authorities and directions for improving the tax administration system; establishment of functional relationship between tax risks and elements of the tax mechanism in the system of ensuring the tax security of region.

Purpose of the Study
The purpose of this study is to review the existing approaches to ensuring tax security and tax risks reduction, as well as author's approach to structuring the elements of identification of treats and uncertainties in the tax sphere for the purposes of achieving tax security in the region.This leads to the revealing of functional connection between tax risks and structural elements of tax mechanism on the basis of planning, regulatory, control and analytical aspects.

Research Methods
Within the framework of this study, the methods of scientific search, comparison, graphic construction, synthesis, modelling, abstraction and concretization were applied.
The practical application of risk identification elements together with tax mechanism instruments enables the prediction of potential positive or negative outcomes within the implementation of particular measures of regional tax policy and allows taking initial steps to minimize the negative impact of tax security threats on the socio-economic development of the state and its regions.

Findings
While understanding the full importance of the category "security" and its ensuring mechanisms, we consider it reasonable to give the term a legislative implementation and define it as a tax system condition, which provides a harmonious development of the tax sphere, opportunities of applying tax instruments in order to guarantee the state interests protection, the maintenance of socio-economic stability in society, as well as establishing the system of financial resources, able to counteract both predictable and unpredictable internal and external threats successfully.
The study revealed that the main source of tax security threats of the state are tax risks.Tax risks are associated with a specific event of stochastic nature.They tend to occur in conditions of insufficient tax legislation, the dual interpretation of legal regulation, the use of illegal tax schemes and the implementation of inefficient tax policy.The process of tax risk management is defined as a mechanism of relevant identification of threats and uncertainties, analysis and assessment of tax situation and establishment of measures to prevent or reduce negative impacts on the economic entity or state (Figure 1).The study found that the reasonable maximum permissible (critical) level of tax risk should not exceed 50% of the total tax debt from actually received taxes (Table 1).The predicted share of total tax debt in the total tax revenues in a region does not exceed the established allowable level of 50%.However, the growth of tax debt in the mid-term perspective should be under strict control and get subjected to detailed analysis by regulatory authorities in order to ensure an adequate level of tax security in the region.

Tax risk management mechanism
Such arrangements as effective operation of a unified data processing center and development of tax authorities' database providing information about taxpayers, financial and economic activities and socio-economic situation in Russian regions may be suggested as preventive measures to increase the efficiency of regional tax authorities.Source: compiled by the authors.
In the process of ensuring regional tax security, it is necessary to take into account interrelation of tax risks not only with managerial factor, but also with other structural elements of tax mechanism (Fig. 2).

Minimization of threats, risks, uncertainties
Achievement of the maximum level of mobilization of tax revenues of regional budgets 2) introduction of the term "tax disqualification" into legislation and professional practice and establishing criteria for the application of tax disqualification, the mechanism for its implementation, the possible periods and reasons for the tax disqualification of individuals and legal entities.

Conclusion
Tax system and tax policy play significant role in ensuring the tax security of the state and depend on specific situation and features of the country's development.It is proved that the implementation of a unified tax policy that provides the balance of interests of all tax parties, tax administration system development will facilitate eliminating threats and ensuring tax security.
In regional tax security system the effective usage of tax mechanism instruments should be focused on a steady development of the real sector of the economy and guaranteeing region's financial self-sufficiency via state support, by stimulating economic activity of the territories and improving the efficiency of using the resource potential.
