Abstract
<jats:p>The article examines current problems that necessitate updating the tax legislation of Ukraine. The purpose of the article is to analyze the problems of adapting Ukrainian tax legislation to the legislation of the European Union in the context of modern challenges (the legal regime of martial law and post-war reconstruction) with the identification of individual ways to solve them. The study of this issue was conducted using various methods (comparative law, analysis, synthesis, interpretation, and others). The relevance of updating tax legislation in accordance with the Association Agreement between Ukraine and the European Union is emphasized. It is argued that Ukraine, despite martial law, continues to reform the tax administration mechanism (using the example of the National Revenue Strategy until 2030, amendments to the Tax Code of Ukraine). Attention is focused on the importance of adopting the Law of Ukraine “On Amendments to the Tax Code of Ukraine and Other Legislative Acts of Ukraine Regarding Payment Services” dated January 12, 2023 No. 2888-IX. In particular, to update the norms of the Tax Code of Ukraine regarding the opening and closing of taxpayer accounts in banks, other financial institutions, non-bank payment service providers and electronic wallets in electronic money issuers. The need for such changes is justified due to a certain inconsistency of the norms of the previous version of Articles 69 and 20 of the Tax Code of Ukraine with European standards. The amendments to Chapters 11 and 12 of the Tax Code of Ukraine and their adaptation to the norms of European law were separately analyzed. Some gaps in the norms of these chapters and the terminological apparatus of Article 14 were identified. In order to comply with the European principle of legal certainty, the following changes have been proposed: to apply only one financial sanction for a committed tax offense - a financial fine, and to consider the penalty as a means of ensuring tax payment. Other ways of updating the norms of the Tax Code of Ukraine and formulating them in compliance with European standards and rules of legal technique (reduction of duplicate norms, redundant and unfounded norms, etc.) are also outlined. The main conclusions obtained are to determine ways to improve the Tax Code of Ukraine and, separately, its terminology by adapting it to the law of the European Union.
