Architectonics of individual taxation system

Transformation of national economies caused by globalization and digitalization of business processes leads to changes in the whole chain of relationships at the levels of "state-individual", "employee-employer", "tax authority-taxpayer". The following research goal is to develop a unified construct of the taxation system, taking into account modern transformation processes and system economy principles. The research applies a comprehensive approach, which includes three main analysis methods: qualitative comparative analysis, simulation modeling, and interpretative qualitative research. Qualitative comparative analysis was used to identify the elements of individual taxation. Simulation modeling was used to visualize taxation main parameters and limitations. Interpretative research was used to describe the interaction of the system elements. The scientific novelty of the research is the presented architectonics of individual taxation system, which develops the theory of system economy of Kleiner and includes 4 elements (subsystems), classified by the criterion of definiteness of time and space. First, objects – exist in the uncertainty of time and the certainty of space. Second, projects - exist in limited time and defined space. Third, environments – exist in the indefiniteness of time and the uncertainty of space. Fourth, processes - exist in limited time and uncertainty of space. The elements of the objective subsystem include taxpayers individuals and individual entrepreneurs, tax authorities, tax agents, other participants of tax legal relations, and the territory. The project subsystem includes tools and mechanisms of tax regulation, which are experimental and temporary in nature. Tax functions implementation was visualized in the context of the presented system.
