Abstract: The subject of the study is the concept of taxpayer integrity in the US law enforcement practice, in particular, the approach of the US tax authorities and the US Tax Court in applying this concept when considering tax disputes. When considering this issue, it was revealed that the signs of the taxpayer's integrity are fixed in the US Internal Revenue Code in Article 1.6664-4. In accordance with the provisions of this article, no fine may be imposed in accordance with section 6662 in respect of any part of the underpayment if the taxpayer proves that there was a reasonable reason for such part and that the taxpayer acted in good faith. В В В  The main conclusion of the study is that the existence of a legal norm defining the signs of a taxpayer's good faith in the US tax legislation allows taxpayers to avoid a fine in case of incomplete fulfillment of tax obligations by providing a reasonable reasonable reason.
In addition, we can conclude that when determining the legality of accepting expenses for the purpose of reducing the income tax base, the US Tax Court takes into account the nature of the appearance of these expenses (case Neonatology Assocs., P.A. v. Commissioner - 115 T.C. 43, 99 (2000), aff'd, 299 F 3d 221 (3d Cir. 2002))

Abstract: Extension of globalization process to the world economy allows conducting the economic activity outside the country of tax residency. It also entailed the emergence of various types of incentives in some jurisdictions, for example, preferential tax regime or non-taxation. Questions related to international taxation are currently most acute. The use of foreign jurisdictions through controlled foreign companies reduces the state tax revenue. For counteracting abuse of the privilege by taxpayers, the rules of controlled foreign companies have been developed and implemented in over 30 countries. On the one hand, the countries accept these rules for preventing tax evasion, which can be changed due to various circumstances. On the other hand, there arise situations when such rules may worsen the situation of the taxpayer. This leads to abuse of the right of regulatory authorities in counteracting tax evasion. The controlled foreign companies (CFC) rules are aimed at determination of actual tax liability of the taxpayer, and do not pursue fiscal, political or other interests that worsen the conditions of the taxpayer.
