Many of the principles of taxation that were developed in the first half of the 20th century, such as the arm’s length principle and the definition of the term “permanent establishment” (PE) in determining the tax position of international business operations, when applied to the business models of the 21st century, often result in the under-taxation of businesses that are otherwise fully compliant with the laws as presently written and implemented. Compounding the problem is the fact that these rules and principles of taxation are broadly recognized and are enshrined in a wide network of tax treaties. This makes the task of modifying or updating these rules and principals extremely difficult. Using legal-dogmatic and legal-theoretical methods, the author will show that present attempts to tax e-commerce transactions unilaterally are not effective and that, under present conditions, even organizations such as the EU are unable to address the problem at hand. The OECD project, commissioned by the G-20, which seeks to create a set of international e-commerce taxation rules, faces some very serious difficulties – largely because a well-established “set in stone” complement of internationally accepted laws, rules, and regulations is serving to block the development of new, more appropriate rules. This phenomenon has become known as the lock-in effect or legal impossibilism. In order to effectively address this phenomenon, lawmakers on a global basis must understand the mechanisms that are blocking the effective evolution of business taxation.

The paper entitled “Counteracting Tax Avoidance and Tax Evasion in Selected EU Directives on Direct Taxes” discusses the provisions of Directive 2003/49/EC, Directive 2009/133/EC and Directive 2011/96/EC that are capable of withdrawing the benefits provided under the directives in the case of tax fraud and abuse, tax evasion or tax avoidance. The paper reviews provisions of the directives and also the case law of the European Court of Justice concerning tax fraud and abuse. The jurisprudence of the ECJ plays a key role in setting standards for regulations on the prevention of tax evasion and avoidance adopted by Member States of the European Union. The paper’s centre piece argument is that the solution adopted by the EU legislator, which shifted the burden of preventing tax escape from the EU to Member States, is ineffective and falls short of fulfilling its proper role. The paper emphasises that many tax payers take advantage of the fundamental treaty freedoms and applicable directives to obtain tax benefits or double non-taxation. Limitations imposed by a strict jurisprudential approach of the European Court of Justice also pose a significant barrier to effective tackling the negative phenomenon of aggressive tax planning based on EU laws, the paper suggests. By assessing the effects of the application of the existing regulations and juxtaposing them with the current scale of the problem, the author presents an argument for changing the direction of measures taken to curb international tax avoidance and evasion.

The working paper aims to diagnose Brexit’s impact on the taxation of Polish-British commercial exchange. This research problem determined in such a way is considered from the point of view of the possible legislative consequences as well as the application of provisions regulating the structural elements of border taxes. The author formulated the thesis that the exit of the United Kingdom from the European Union will be an event that will significantly affect the changes in tax and customs qualification of the exchange of goods between Poland and that country.

The article aims to cover the issue of foreign entities having a “fixed establishment” in a given country. A phenomenon discussed at length in recent months, but one that entities conducting digital business seem to have not really explored in great detail in the context of determination of the principles of taxation of VAT transactions. In this article, we will attempt to analyse the definition of FE on the basis of both binding legal regulations and the existing Polish and EU judicial decisions. At the same time, we will try to answer the question about the impact of the practice of tax authorities pursued in the area of interpretation of the conditions for a FE to be established on the stability of tax settlements of taxpayers operating in the digital industry. In addition to that, the authors will also try to arrive at a balance among the current views on FE, which depict Poland from the tax administration perspective as a country with highly unstable tax practices, detached from logical arguments and unaware of the nature of business.

The author is searching for an answer to the question of whether the European Union needs own solutions in the area of taxation of digital economy and whether the solution offered by the European Commission, which is taxation of significant digital presence, can be effective in taxing the digital economy of the European Union. To this end, a number of references to selected standpoints of international doctrine, OECD regulations, and the draft of the Directive has been made in this paper.

This paper presents an analysis of legal issues related to the use of a blockchain in business. Considering the legal aspects at as early a stage as possible is one of the key areas which are crucial for the success and timely realisation of a project. The scope of legal issues depends on the type of the decentralised solution chosen by the organisation. The authors explain the differences between an open blockchain and a closed one, noting the degree of control and the advantages of both solutions. When it comes to the following paragraphs of the paper, the meaning of jurisdiction selection and the manner of managing personal data in projects related to the use of blockchain are discussed. The authors explain what smart contracts are to the reader. They point out sector regulations which may have an influence on the carrying out of blockchain projects in individual sectors that are regulated. They analyse the issues of the cryptocurrency market and explain to the readers why the taxation of cryptocurrencies is controversial. In the final part, they signal that organisations planning to implement a blockchain-based solution should take the Anti-Money Laundering (AML) regulations and related issues concerning Know Your Customer (KYC) into consideration. The paper makes it possible to understand why the legal regulations discussed may turn out to be an essential project risk if they are not recognised in time, and how addressing legal issues smoothly helps in the transformation of a project at the Proof of Concept stage, into a solution that works productively.

The paper aims to show that the Polish Environmental Law is an act that imposes
public imposts to protect Poland’s natural environment. This act features certain
specific qualities and legal solutions. The author has formulated a claim that some
of the provisions concerning the fees for the use of the natural environment and
the emissions surcharge breach the constitutional standards of exclusivity of an
impost act, of the right to predictable taxation, decent legislation, and a democratic
state of law.

The subject of this article is the analysis of reasons and results of determining as well as changing tax residence in the light of Polish personal income tax. This topic underlies a broad concept of migration, especially that of profit-driven character. The author presents this research issue on the basis of the current legislation, doctrine as well as practice of applying the law by the judiciary and the tax autho-rities. The analysis of the valid regulations of tax law leads to the conclusion that the fiscal situation of migrants is so diversified as well as complicated from the legal point of view that it raises justified practical doubts. It is assumed that tax residence is dynamic and thus may change as a result of both intended and unin-tended taxpayers’ actions which may have specific tax law effects. They are reflected not only in tax preferences but also in obligations concerning tax settlements. Apart from ordinary tax consequences of determining or changing tax residence, the author relates also to particular legal solutions such as: exit tax, taxation of foreign controlled companies or appliance of the provisions of Multilateral Convention (MLI). The described issues are significant for both theory and practice of tax law application.

A review of solutions which serve the taxation of the digital economy allows for the statement of a thesis that there are many methods which could tax business activity based on digital technologies. One should remember, however, that there also must be consensus and political will in order to introduce them. Due to the lack of consensus at the global level, on 21 March 2018, the European Commission presented two draft directives which were to ensure the taxation of enterprises conducting business in the European Union in the area of digital economy: the Directive laying down rules relating to the corporate taxation of a significant digital presence and the Directive on the common system of a digital services tax on revenues resulting from the provision of certain digital services. The drafts of the Directives presented by the Commission are the beginning of the legislative work at the Union level. One should ask the question whether the European Union needs its own solutions regarding the taxation of the digital economy. In this paper,
the author attempts to evaluate whether the target solution proposed by the Commission, that is, the taxation of a significant digital presence, i.e. a digital establishment,
can be an effective tool for the taxation of the digital economy in the European
Union. For this purpose, subsequent references were made to selected opinions
of international doctrine, OECD regulations and the draft of the Directive.

The subject of this paper is the taxation of a security transfer of title to a fixed property with the tax on goods and services. The author focuses on the interpretation of the term “paid supply of goods” in the context of a security transfer of title. The objective of the following considerations is to establish whether a security transfer of a title is a chargeable event, and to indicate the moment in which the tax becomes chargeable on the grounds of the goods and services tax and in the light of the absence of a consistent practice of the tax authorities as well as divergent judicial decisions of administrative courts on the matter.
