Abstract
<jats:p>This article examines international taxation as an important tool for regulating global economic and financial processes in the context of globalization, the digitalization of the economy, and increased international coordination of tax policy. It is argued that modern international taxation goes beyond the traditional fiscal approach and is taking on the characteristics of a systemic regulator of international capital flows, investment flows, tax competition among states, income redistribution among jurisdictions, and the assurance of financial stability. Scientific approaches to interpreting the essence of international taxation are summarized, and its main functions are identified: fiscal, regulatory, coordinating, redistributive, and stabilizing. It is demonstrated that international tax agreements, transfer pricing mechanisms, and the concept of a global minimum tax play a special role in the transformation of the international tax environment. It is determined that these instruments form a new architecture of international tax coordination aimed at reducing destructive tax competition, increasing the transparency of international financial flows, and ensuring a more equitable distribution of taxing rights among states. Particular attention is paid to the impact of the digitalization of the economy on international taxation, as the growing role of digital platforms, intangible assets, and virtual business models complicates the application of traditional approaches to determining tax presence and necessitates the modernization of tax administration. It is argued that international taxation is of fiscal and strategic importance for Ukraine, as it involves adapting national legislation to European and global standards, strengthening control over transfer pricing, improving the network of tax treaties, and enhancing the country’s financial security. The practical significance of the results lies in the possibility of using the formulated provisions to improve tax policy, develop international tax coordination, and enhance the effectiveness of state regulation of global financial processes.</jats:p>
