The aim of this article is to answer the question whether taxpayers are entitled to any subjective rights that are overtly, unambiguously and legibly laid down in tax law. The author presents the title issue by analysing a broad base of judicature by
Poland’s CT, the EUCJ and Poland’s administrative courts, also discussing the relevant literature concerning subjective rights as coded in the provisions of the Polish Constitution and tax law. Taxpayers’ subjective rights may constitute an effective protection measure not only vis-a-vis the administrative discretion of tax authorities, but also in the event of their abuse of administrative power in relations with entities obliged to pay levies.

The objective of this study is to discuss the principles of the lump-sum personal income tax applied in Poland in the years 1950–1997. The analysis of the aforesaid historical legal constructs could, to a certain extent, constitute a benchmark for legislators and reformists of the current Polish personal income tax and, in practice, appear (at least for certain groups of taxpayers) to be an attractive and alternative form of income burden.

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 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.

One of the most effective systems of protection of human rights is the system defined in the European Convention of Human Rights. Until 2010, the European Court of Human Rights had rarely handled tax cases because, in principle, it excluded this category of cases from its jurisdiction in the field of the protection of taxpayer rights. Such cases had always been qualified – in accordance to the requirements of Article 6 of the European Convention on Human Rights – as criminal or civil (property-related) cases. A major change in the ECHR’s approach to cases featuring tax-related aspects occurred in 2011. Given the protection of the right to property as set out in Protocol No. 1, the ECHR ranted taxpayers protection related to the return of value added tax in situations in which the taxpayer fulfilled their record-keeping obligations. The adopted trend in the issued decisions is seen to be dominant, but to be considered grounded, a greater number of ECHR judicial decisions than at present is needed. There is no doubt that the new tendency in the judicial decisions issued by the ECHR may have a major impact on the decisions issued by administrative courts in Poland.
