In recent years, the resistance of member states to the strengthening of the European Union and its ambition to extend the powers of nation states has become a dominant political element, especially in the countries of the Central and Eastern European region. At the same time, both nation states and the EU are facing a number of global challenges, one of the most significant of which, alongside climate change, is digitalization. At the dawn of the digital age, technological innovation and the free flow of information promised unprecedented opportunities. However, as digital technologies have increasingly permeated all aspects of economic, social and political life, they have created new crises and challenges, particularly with regard to digital sovereignty. This research explores the complex and interdisciplinary nature of digital sovereignty, with a particular focus on the crises that digitalization has triggered and caused. These crises manifest themselves in various forms, including cybersecurity threats, privacy issues and the economic dominance of global technology companies. The European Union’s legislative initiatives, including the Digital Services (DSA), Digital Markets (DMA) and European Media Freedom (EMFA) regulations, as well as the efforts to regulate artificial intelligence, are designed to address the crises inherent in the digital age, while at the same time posing new challenges to the sovereignty and perception of sovereignty of individual states. The research examines the EU’s legislative efforts in navigating the politics of digital crises. It sheds light on the interplay between national self-determination and the EU’s overall regulatory framework, highlighting the ongoing struggle to balance control and cooperation in a rapidly changing digital environment. The analysis will provide a deeper understanding of how digital sovereignty is shaped by and responds to crisis policy, and insights into the future of digital governance in an increasingly interconnected world. It also seeks to assess the extent to which recently introduced EU legislation can be harmonized with the policy objective of strengthening the autonomy of nation states. This is particularly important in the context of the legislation and practices observed in countries with relatively small populations, such as Hungary, Slovakia and the Czech Republic.

Tax payment is the basic form of fulfilling a tax obligation. It is included in the effective method of removing tax liabilities. As part of the control of payments of local taxes carried out by the tax authorities, it was found that an unauthorized employee of this authority unlawfully accepted payments of taxes that he did not pay to the account of the tax authority. A legal doubt has arisen in this respect as to whether the payment made in the above-mentioned circumstances is the payment of tax that gives rise to the removal of the tax liability. The main goal of the authors, within the research topic undertaken, is to verify the research hypothesis, according to which the taxpayer's transfer of funds to an unauthorized employee of a tax authority, confirmed by a receipt, cannot be considered as payment of the tax. The study analyzes the above-mentioned issues on the basis, above all, of the provisions of Polish tax law, which do not define the concept of tax payment, although they indicate the forms of payment. In order to get a broader perspective on the subject matter, the author analyzed selected regulations concerning the above-mentioned issues in Hungary and Ukraine.

Ensuring the sustainability of public finances is a crucial concern for the European Union, particularly in the context of transfer pricing, which is focused on tax base erosion and profit shifting. Transfer pricing, involving the internal transfer of goods, services, or intellectual property between related entities, can significantly impact member states' tax revenues and overall economic stability. Base erosion and profit shifting is a term used to describe tax planning strategies that multinational companies use to exploit gaps and mismatches in tax rules to artificially shift profits to low or no-tax jurisdictions, thereby reducing their overall tax liability. The scope of this study examines these two topics, mainly by using jurisprudential methods and analysis of scientific sources, as well as to research the effect of tax-based erosion and inequality among state jurisdictions. The assessment and analysis of the problems in these areas have been going on for years, and in essence, the neuralgic points are clear in terms of problem definition. Nevertheless, appropriate normative solutions have either not been developed to a full extent or are being implemented slowly. Considering the lengthy process of adopting normative rules, the main aim of this study is to make suggestions for the field of law enforcement and organs of public administration that could lead to changes in the areas of transfer-pricing, base erosion, and profit shifting. In conclusion, three key areas of action are proposed. Firstly, the promotion and everyday implementation of digital taxation contribute to the efficient exchange of data. Secondly, much closer cooperation between tax authorities on this basis can be strengthened at the Member State level in practical administration. Thirdly, the more effective safeguarding of the single market by national administrations.

This article examines how addressing climate-related risks and supporting mitigation and adaptation policies fit into central bank mandates. According to this goal, the research conducts an empirical examination of current central bank mandates to investigate the extent to which central banks are equipped with objectives that task them to enhance sustainability and mainstream green finance. The analysis of mandates and objectives using the IMF’s Central Bank Legislation Database. Out of 159 IMF member countries and monetary unions, only 12 % have explicit sustainability mandates, while 33 % are mandated to support the government’s policy priorities, which mostly include sustainability goals. The research concludes that it should be clear that climate change and mitigation policies will have very profound impacts on economies, with potentially significant implications for price, macroeconomic, and financial stability. These need to be tackled by central banks as part of their core responsibilities. A central bank that does not address climate risks is failing to do its job.

This paper examines how financial supervisory authorities integrate Environmental, Social, and Governance (ESG) objectives into their regulatory mandates amid the accelerating green transition. It aims to understand how institutional variation shapes supervisory strategies for sustainable finance. The study employs a qualitative, comparative case study design across three jurisdictions: the European Union, Hungary, and Singapore. Drawing on regulatory theory and document analysis, this study identifies the key institutional logics, instruments, and governance mechanisms through which ESG considerations are embedded in financial supervision. The analysis reveals three supervisory models: the EU's rule-based legal harmonization through taxonomy and disclosure mandates, Hungary's responsive approach led by the central bank using soft tools and innovation, and Singapore's principle-based framework emphasizing strategic guidance and market collaboration. These pluralistic pathways highlight that ESG integration is shaped by legal mandates, legitimacy concerns, and adaptive governance. This study provides insights to policymakers and supervisors seeking to align financial oversight with sustainability objectives. This emphasizes the importance of institutional flexibility, regulatory legitimacy, and hybrid governance in designing effective ESG supervision frameworks. This study contributes to the literature on sustainable finance and regulatory governance by offering a comparative perspective on how financial supervision evolves in response to ESG risks. It advances a novel typology of supervisory models that can inform future regulatory design and policy debates.
