In the conditions of permanent capital outflow and business registration by residents in other jurisdictions, the issue of developing a country’s marketing strategies for doing business and identifying the most effective mechanisms for increasing international tax attractiveness is urgent. The prerequisite of these processes should be the determination of the level of international tax competitiveness followed by identifying the most significant factors of its growth. The purpose of the study is to assess the level of international tax competitiveness as an element of marketing strategies of Ukraine and some EU countries during 2011–2021. The methodological tools are correlation-regression analysis, the Fisher method, and the multiplicative convolution method. The paper assessed the level of international tax competitiveness as a comprehensive indicator that considers procedural, institutional, moral-ethical, and economic components. The calculations showed that the most competitive are the tax systems of Estonia, Latvia, Lithuania, Croatia, Finland, the Czech Republic, and Hungary. Based on hierarchical and non-hierarchical (k-means method) clustering, 3 clusters of regions were identified. For each of them, based on an analysis of the features of the tax system construction and the comparison of marginal and average values, the criteria for the identification of competing countries and those with common development trends were formed. This makes it possible to determine the most effective mechanisms for the implementation of marketing strategies reforming tax policy from the point of view of increasing its international tax attractiveness.
