During the examination of tax education, a significant part of the professional literature defines taxpayers as a homogeneous group, however, among others, the level of educational attainment and the digital skills of taxpayers are also important. This research investigates the role of knowledge in connection with tax compliance. The article is based on the statements from the professional literature and analysis of secondary data from national and international authorities and institutions. It also includes some comparisons of the components of the COM-B model on the data of nine European countries and sets up a model of tax behaviour based on Hungarian conditions. According to the classification based on the comparison, the performance of Hungary is at the lowest level among nine examined countries. Considering the complexity of the tax system, the knowledge of taxpayers is incomplete in Hungary. A developed version of the COM-B model points out that there is a close connection between capability and opportunity as well and these components can reinforce each other. With the adequate motivation and literacy as well as the knowledge of procedures can facilitate tax compliance. It can be concluded that successful tax education recognises and targets various groups of taxpayers. The Hungarian tax authorities treat taxpayers as a homogeneous group, however, there are slight developments by using several communication channels. In the current situation, the most important is to find the forms and levels of tax education to make the taxpayer able to comply.

Purpose: The purpose of this study is to provide a systematic review of research development on auditing in the European Union over the past decade and suggest future research directions. Design/methodology/approach: Following the PRISMA protocol, the authors systematically reviewed the relevant literature and conducted a qualitative content analysis of 107 studies on auditing in the European Union published between 2012 and 2023. Findings: The results indicate increased auditing literature in the European Union from 2012 to August 2023. Around 40% of the papers were focused on six nations: Germany, Spain, Italy, the UK, Sweden and France. Additionally, 35.5% of papers have been published in three major journals: Accounting in Europe, International Journal of Auditing and the European Accounting Review. Moreover, 82.24% of papers used quantitative methods, with a few using qualitative or mixed methods. Also, most of the studies in the sample endorsed the European Union’s auditing reforms, which included implementing a cap on nonaudit fees and enhancing the independence of audit committees. Contrary to this viewpoint, multiple studies have expressed disagreement with enforcing a total prohibition on nonaudit services, as certain services can enhance auditing quality. Similarly, other studies have contested the necessity of mandatory auditor rotation every 10 years, citing the significant additional expenses associated with this practice. Finally, further studies supported the European Union’s decision to make the joint audit voluntary, as it is related to high audit fees and low audit quality. Research limitations/implications: The limitations of this research primarily stem from the authors’ choices in selecting the database and defining the criteria for searching the studied papers. Practical implications: This paper offers valuable insights into the future research prospects in the European Union’s auditing field. Hence, this analysis can be helpful for researchers and practitioners in developing this field based on future research recommendations and the identified themes. Originality/value: To the best of the authors’ knowledge, this paper is the first study to systematically review the developments of the European Union auditing literature over the past decade.

Purpose: The objective of the study is to highlight the relevant contexts and problems of the Hungarian tax administration from the aspects of digitalisation, communication and education between 2018 and 2022. Methodology/approach: The article is based on the statements from the professional literature and analysis of secondary data from national and international authorities and institutions. The article makes several comparisons. Findings: The article shows how Information and Communications Technology (ICT) is used in tax administration in Hungary, filling the research gap. Based on the comparison, the digital development of Hungary is similar to that of the EU average. However, there are some impediments, such as the complexity of tax regulations and the numerous communication channels that exist. They could be simplified, and our proposed modifications in terms of communication and education could improve the use of ICT in the Hungarian tax system. Research limitations: The research does not provide an in–depth examination of Hungarian tax legislation and lacks any primary research. Originality/value: The article deals with some aspects of tax administration in Hungary; it describes the current situation and gives proposals for its development.

The eXtensible Business Reporting Language (XBRL) digital reporting system presents the annual accounts and financial data in a standardized format, thus producing comparable reports. This study examines how new sustainability reporting requirements proposed by the recent International Financial Reporting Standard (IFRS) S2 exposure draft could affect current reporting conditions of public listed European automotive manufacturers, from a taxonomical perspective. It was attempted the IFRS taxonomy to be linked with the ISSB's (International Sustainability Standards Board) proposed factors. Based on the changes in the regulatory environment and the existing digital reporting methodology, the paper proposed the inclusion of climate-related disclosure of automotive companies in the existing IFRS Taxonomy. In the taxonomical assessment, it was found that the recent sustainability reporting prototypes will likely affect certain financial statement sections, mostly the Notes to the financial statements. At present, there is no direct information available to investors and consumers on the environmental performance, which could be verified in the financial statements. There is no detailed emissions data that the company produces, as it is mainly the emissions compliance of the final product that is declared, especially in the automotive industry.
