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.

This paper concerns a broader technological revolution which is currently happening all around the world, including Poland, in terms of tax return completion. The paper is divided into parts. The individual parts indicate and describe the current state, change-causing factors as well as the changes progressing currently both in Poland and the world. The purpose of this paper is to analyse and describe the possibilities resulting from the automation of the tax returns completion process and to determine the directions of potential changes in the future.

This article aims to show the similarity between the arguments developed regarding the Treaty freedoms and the approach to the legal principles proposed by R. Alexy. Treaty freedoms from the Treaty on the functioning of the European Union, developed in the course of the Court’s many years of judicial activity, have a number of similarities to the concept of the principles of law proposed by prof. Robert Alex. This is evidenced by – the position of the principles of law in the legal system, the possibility of grading them, or a separate method of resolving the conflict of two opposing principles of law. The article analyses selected treaty freedoms in relation to tax matters and compares them with theoretical schemas proposed by prof. Robert Alexy.
