Abstract: In view of the low income level of a substantial part of the population in Russia and Kazakhstan, pronounced differentiation by income and social stratification, it is appropriate to introduce progressive taxation for individuals as required by the laws of economic development, despite the existing political imperative that determines the economic course. The article provides mathematical justification of the quantitative values of progressive scale based on the authorial software product of the model of optimal income tax for individuals that allows to accurately calculate the progressive rates considering various factors. The object of this research is the system of taxation of individuals; while the subject is the methods of quantitative determination of the boundaries of taxation of individuals with different income, consequences for the budget and population. The research employs the methods of comparison, generalization, statistical and economic-mathematical methods were used. The development of software product of the model of progressive income tax requires a particular method of mathematical substantiation of quantitative values, precision and convenience of economic-mathematical calculations. The authors developed the software product for personal income taxation based on the methodological provisions proposed by O. V. Kalinina. Such product allows calculating progressive rates of personal income tax, taking into consideration various factors. The conclusion is made that the transition from a flat to a progressive scale characterizes the social nature of redistribution of tax burden among population. Moreover, it would increase revenues into the state budget.

The scientific novelty consists in comprehensive research of the internal control of tax obligations, determination of its essential characteristics,  and assessment of the consequences of formalization of requirements thereof, which led to the conclusion on transformation of the internal control of the taxpayer from the area of reputational merits of the economic entity and internal administration instruments to the subject of public control by tax authorities in tax monitoring processes. It remains to be seen whether state interference in such delicate sphere of activity of an economic entity as internal control is justified. The goal of this research consists in the analysis of the effective requirements of the Federal Tax Service of Russia from the perspective of possibility of their implementation by the particular taxpayers. The article provides the examples of assessment of certain components of the internal control system based on the criteria set by the Federal Tax Service of Russia.

Abstract: Countering the practice of conducting business through several companies for obtaining tax benefits, or in other words, the practice of businesses is fragmentation is a relevant problem not only in the Russian Federation, but also foreign countries. Namely in Canada, small business are qualified for reduction in corporate tax – small business deduction (SBD). At the same time, it substantiated the need for the development of special financial-legal means for preventing taxpayers from misusing it. This article examines the Canadian experience of countering business fragmentation, and discusses various legal means implemented by the Canadian legislator. Special attention is given to the analysis of law enforcement practice of these legal means, including introduction of the “deemed association rule” (Paragraph 2.1, Section 256 of the Law “On Income Tax”). Foreign experience pertinent to legal regulation of countering the practice of business fragmentation has not previously become the subject of detailed analysis, which defines the scientific novelty of this article. The conclusion is made that Canada has a separate legal regulation in form of  the general and special rules aimed at prevention of unscrupulous practices of business fragmentation. The Canadian tax authorities may apply certain special norms prior to resorting to broader discretion. Application of the “deemed association rule”  based on determination of the purpose of separate existence of corporations, draws particular attention. The Canadian law enforcement practice developed the approach, according to which the implementation of this rule should be founded on the objective component and documentary evidence.
