Abstract: The subject. The subject of the research is the grounds for improving individual taxation system (taxation of residential property) based on the development of models for their cadastral valuation and prediction of consequences of individual taxation decisions. The object of the research is the mutual relations and mutual influence arising in the process of individual property taxation based on state cadastral valuation. The purpose. The purpose of the research is to make recommendations on how to improve procedures of calculation and collection of individual property (residential property) tax based on state cadastral valuation. Methodology. The theoretical and methodological basis of the research is the concepts and fundamental provisiosn in the sphere of taxation theory, theory of property valuation, theory of public finances reflected in monographs, researches and practice-oriented findings of foreign and Russian authors, publications of research centers, and legal acts and laws of the Russian Federation and its constituents. The adequacy of conclusions is guaranteed by the combination of approaches and methods such as systems approach, analytical method, method of documentary sources analysis, and method of comparative analysis. Based on the crtical analysis of the Methodological Guidelines on State Cadastral Valuation (2016) the authors have discovered provisions that are not sufficiently grounded and thus do not allow to perform a correct calculation and collection of individual property tax. Based on the systems approach, the authors have made recommendations on how to improve the method of residential property valuation as well as to reform the existing system of property taxation in general. At the present Russia has made serious steps towards developing an efficient individual property (residential property) taxation system. However, the results of the author's analysis demonstrate that there is still much to be done to develop the theoretical, methodological and instrumental basis of the reform.
