In the Russian Federation taxes are calculated based on the cadastral value of immovable property, formed on market information, including information related to the economic characteristics of using of a real estate object. This creates conditions for the rational and efficient use of land plots and capital construction projects (capital construction object). However, it is worth noting that today these conditions are poorly implemented due to biased cost indicators forming the base real estate taxation. The purpose of the study is to test methodological tools for calculating the cadastral value of a capital construction object, taking into account adjusted effective age in the context of sustainable development of the region. When performing repair and restoration work, physical wear is compensated only partially. In this regard, the cost of a constructed building and the cost of a building that was overhauled or reconstructed in the same year are not equivalent to each other. The proposed by the authors corrected effective age allows us to reflect the content of difference between the year of construction and the year of reconstruction or overhaul as a whole. This makes it possible to resolve the issue of using such a pricing factor as a date of overhaul (reconstruction). At the moment, regions do not have a unified position in a practical approach to this issue. To demonstrate the applicability of methodological tools, the assessment of cadastral value was carried out within the framework of the cost approach. The sample used includes 132 objects, residential and non-residential buildings located on the territory of the city of Tomsk, in respect of which reconstruction was carried out. The results showed that the calculation models of physical depreciation of a building based on corrected effective age become more flexible because partial compensation of physical depreciation is taken into account during the renovation. In total, these measures lead to the accuracy increase while calculating the cadastral value.

The authors consider the cadastral valuation system in the Russian Federation. There is a variety of studies, but there is an active contestation of the results of the cadastral assessment, which leads to citizens' dissatisfaction with the overestimated tax burden, as well as unstable budget planning in terms of tax collection due to biased cost indicators. In this connection, the category "disproportion" has been clarified in the context of the assessment of the cadastral value, which affects the formation of the tax base for real estate objects. The purpose of the study is to develop methodological tools to calculate the cadastral value, taking into account the adjusted effective age of a capital construction facility. The cost of a constructed building and the cost of a building that underwent overhaul or reconstruction in the same year are not equivalent to each other, because repair and restoration work reduces wear and tear only partially. The use of tools that shows the difference between the year of construction and the year of reconstruction or overhaul as a whole makes it possible not only to reduce the information imbalance in determining the cadastral value, but also the methodological disproportion in relation to the use of such a pricing factor as “the date of the overhaul (reconstruction) ", because the regions do not have a unified position in practice. Also, the use of the parameter "effective age" allows you to reasonably apply the methods of income, cost and comparative approaches.
