This article provides a comprehensive analysis of the theoretical, methodological, and institutional aspects of implementing a mass property valuation system in the Republic of Uzbekistan. The study substantiates the limitations of traditional cadastral valuation methods in an economy based on market mechanisms and reveals the necessity of introducing a transparent and automated mass valuation system aligned with international best practices. The paper presents a comparative analysis of individual and mass valuation approaches, highlighting their role in tax base formation and functional differences. The advantages of using GIS technologies, mathematical and statistical models, large-scale data (Big Data), and multiplicative valuation models in the mass valuation process are demonstrated. In addition, ongoing reforms, the regulatory and legal framework, institutional structures, and step-by-step implementation mechanisms of the valuation system are analyzed. The research findings contribute to fair and economically justified property tax assessment, stabilization of budget revenues, and increased transparency in the real estate market.

In this article, the economic importance of real estate, the fact that real estate taxation increases the competitiveness of property and has an important place in determining the tax base, are developed based on the analysis, and relevant recommendations are developed.

This article examines the key policy decisions related to the tax base and rates of real estate tax, as well as the important tax administration functions–valuation, calculation, and collection. It also focuses on reforming both the traditional annual property tax (levied on the assessed value of buildings and land plots) and transaction taxes (collected as a tax or state fee [stamp duty] upon the transfer of real estate ownership). The article provides proposals and recommendations for successfully implementing real estate tax reforms and improving tax administration. Based on the analysis of scholarly literature and international experience, detailed recommendations are offered on the practical aspects of reforming real estate taxes in Uzbekistan.
